COMPLETE SPECIFICATION
The following specification particularly describes the invention and the manner in which it
is to be performed.

BACKGROUND
[0001] Owing to the necessity and complexity involved with the
functions performed by railway, it may be crucial to periodically perform the maintenance and electrification operation to keep the railway standards up to the mark. Examples of maintenance and railway electrification work includes, but are not limited to, installation or repairing of overhead electrical equipment, such as transmission lines, distribution lines, transformers, switches, and the like. Typically, the railway electrification work is performed at a portion of a railway track or near the railway track, such as at a worksite or a construction site. These worksites are located either near the railway track or on the railway track, and may require large number of workers due to their labour intense nature. Due to the presence of large number of workers at these worksites and the worksite is located near the railway track that it may pose serious accidental scenarios and drawbacks. To this end, during such railway electrification work, close monitoring of such worksite location along with monitoring of the movement of trains/locomotives on the railway track is required to prevent unsafe conditions and fatalities of workers at the worksite location.

The figures are not necessarily to scale, and the size of some parts may be exaggerated to more clearly illustrate the implementation shown. Moreover, the drawings provide implementations and/or examples consistent with the description, however, the description is not limited to implementations provided in the drawings.
DETAILED DESCRIPTION
[0007] A worksite refers to an area where work, such as electrical
work, construction work, and the like, is done by a plurality of workers. In certain cases, such worksite may be in vicinity of a vehicular track, such as a railway track, a road, and the like. As would be understood, a number of heavy machinery and tools may be present or may be operated at the worksite that may be in vicinity to the vehicular track. For example, the workers at the worksite may perform electrification of the railway track, specifically, electrification of a part of the existing railway track. In this regard, electrical work and civil work may be performed on the part (i.e., at the worksite) of the existing railway track. Examples of the electrical work and civil work may include, but is not limited to, installation of electrical masts, meter box, Overhead Equipment (OHE), power system, over-head electrification system, and any maintenance operation of any electrical equipment or of the railway track.
[0008] Owing to the continuously operating nature of the railway
track, i.e., presence of railway vehicles such as trains or locomotives on the vehicular track , there may be vehicular movement or railway traffic thereon. In such a case, the workers working at the worksite require accurate information or scheduling information regarding movement of the railway

vehicle over the railway track which may be provided by providing access to the railway network. However, the railway authority does not provide access of the railway network to the workers working at the worksite location. In such a case, to perform maintenance and electrification work, a predictive time window is provided to workers to carry out the work on the worksite based on the tentative schedule of railway vehicles on the railway track by an authority, such as railway authority. Due to the inaccurate nature of the information pertaining to the movement of railway vehicles, work to be performed on the worksite may be affected during, for example, delay in incoming railway vehicle, or diversion of a railway to and/or from the railway track.
[0009] To this end, manual supervision of the railway track in
upstream and downstream directions of the worksite may need to be performed. Conventionally, supervisors, such as safety marshals, safety inspectors, or security personnel may be positioned in proximity to the railway track, away from the worksite location, in both the upstream and downstream directions to monitor any movement of railway vehicles on the railway track. On detecting an incoming railway vehicle on the railway track, the supervisors may alert the workers on the worksite via communication devices, such as mobile phone, walkie-talkie, and the like to timely evacuate the worksite.
[0010] The alert provided by the supervisor indicating movement of
the railway traffic towards the worksite location needs to be communicated in timely manner so that the workers working at the worksite may timely evacuate the worksite to provide a free passage for the railway traffic and itself moves instantly to a safe zone. For example, workers installing an overhead electrical equipment (OHE) on the railway track may require about 10-20 minutes to disassemble or move electrical equipment, ladder, platform or other tools, away from the railway track. Therefore, the supervisors may be positioned about 5kms to about 10 kms away from the worksite in both the directions for receiving such alert in time.

[0011] However, manual supervision of the railway track is prone to
human error. Supervisors may not be able to provide or monitor the railway track closely in view of the coming railway traffic thereby failing to provide the alert in a timely manner. In certain cases, the supervisors may not have information about demographics of entire area, i.e., the railway track, the worksite and nearby area. In such a case, the supervisors may not raise alert in time or raise false alert thereby putting workers on the worksite at risk and risking progress of work at the worksite as well.
[0012] Further, even if the supervisor timely alert workers at the
worksite but it may be noted that the railway traffic operating on the railway
track is imperceptible and unpredictable. Therefore, it is difficult for the
manual supervisor to provide information regarding speed of the railway
traffic on the railway track and may fail to reliably and promptly communicate
the alert thereby giving the worker very small time for vacating the worksite.
Further, in certain cases, the worksite may be in a remote area, lacking
reliable communication channel. In such a case, providing prompt alert
using conventional communication devices may become even more
difficult. Therefore, manual supervision fails to ensure safety of the workers
and may hamper stability of work to be performed at the worksite. Moreover,
such lack of reliability on manual supervision may result in fatal accidents
on the worksite. Therefore, workers at such worksites near or along the
railway track are at increased risk of worksite accidents and hazards.
[0013] Example approaches for monitoring vehicular movement, i.e.,
railway traffic over a vehicular track and alerting workers at a worksite location, are described. Such monitoring of the vehicular track and providing alert to the workers at the worksite location may be implemented using a monitoring device. In one example, the monitoring device is positioned near the worksite location and is communicatively coupled over a network with plurality of sensor devices, which may be positioned near the vehicular track. In an example, the worksite location may be a part of the vehicular

track or is situated near the vehicular track, i.e., at an extension of the vehicular track.
[0014] Further, the plurality of sensor devices may be positioned at a
distance apart from the worksite location in upstream as well as downstream
direction. In one example, the sensor device nearest to the worksite location
in upstream and downstream direction is positioned at 5 to 10Kms from the
worksite location. Further, each of the sensor devices positioned near
vehicular track may be spaced apart from each other with a predefined
distance, e.g., 1-2 Kms. In an example, each of the sensor device of the
plurality of sensor devices is a fusion sensor device including combination
of different sensors. Examples of such sensors include, but may not be
limited to, a vibration sensor, a noise sensor, a pressure sensor, thermal
sensor, a photoelectric sensor, an accelerometer sensor and many more.
[0015] In operation, each of the plurality of sensor devices may
monitor the vehicular track to detect any railway traffic thereon. The sensor devices deployed at a specific location near the vehicular track may monitor the specific location or portion of the vehicular track to detect the presence or movement of the railway traffic. In an example, the sensor device may monitor track parameters within the corresponding location or portion of the vehicular track to detect any vehicular movement due to an incoming or outgoing railway traffic on the vehicular track. Examples of such track parameters include, but may not be limited to, vibration value indicative of the vibration in the vehicular track due to the movement of the railway traffic, sound value indicating sound of the railway traffic detected by the noise sensor, photoelectric value indicating presence of the railway traffic on the vehicular track, pressure value indicating pressure applied by the railway traffic over the vehicular track, temperature value indicating variation in temperature due to the movement of the railway traffic over the vehicular track.
[0016] Thereafter, the plurality of sensor devices may transmit the
monitored track parameters to the monitoring device deployed at or near

the worksite location. Specifically, each of the sensor devices of the plurality of sensor devices may transmit track parameters for their corresponding location, to the monitoring device at the worksite location. On receiving the track parameters from the sensor devices, the monitoring device may process the track parameters. The monitoring device processes the track parameters based on worksite parameters associated with the worksite location where the workers are working for any maintenance or electrification work. For example, the monitoring device 108 may interface with a user to obtain the worksite parameters or obtain the worksite parameters automatically, for example, using location services.
[0017] In an example, the worksite parameters may include, but may
not be limited to, geographical location of the worksite, worksite location identifier, monitoring device identifier, locations of sensor devices, distance between sensor devices, sensor devices identifiers, demographic information associated with the worksite, demographic information associated with the vehicular track, and identifier associated with user devices associated with the worksite location. For example, the monitoring device may ascertain, based on the worksite parameters and the track parameters, movement information including, distance between the moving railway traffic and the worksite location, speed of the upcoming railway traffic, and direction of movement of the railway traffic on the vehicular track. Based on this, the monitoring device may generate an alert signal if the railway traffic is determined to be approaching towards the worksite location.
[0018] Based on the processing of the track parameters to ascertain
movement information, the monitoring device may decide to generate an alert signal for alerting workers to evacuate the worksite location. For example, on ascertaining that the railway traffic on the vehicular track is approaching towards the worksite location, the monitoring device may generate the alert signal to alert workers at the worksite location so that the workers may timely evacuate the worksite location. In one example, the

monitoring device may transmit the alert signal to an alarm system to appropriately alert the workers. For example, the alert signal may be a digital signal which may be used by the alarm system which includes a loudspeaker, a light indicator, a display device, or combination thereof to alert the workers. In such a case, the alarm system may receive the alert signal from the monitoring device and accordingly provide the alert to the workers of the worksite location based on the type of component included in the alarm system. For example, an audio message for alerting is provided for a siren or a loudspeaker, a light indicating alert is switched on for a light indicator, and a time of response or a time of evacuation is displayed for a display device. In another example, the monitoring device may be in communication with user devices of the workers and sends an alert message or indication directly to each of the user devices. In this manner, safety of operation at the worksite location may be ensured.
[0019] On receiving the alert, the workers may evacuate the worksite
and move to a safe zone. In one example, in addition to the alert signal, the
monitoring device may also generate a time of response for evacuation of
the worksite location. On the other hand, on determining that the railway
traffic on the vehicular track is moving away from the worksite location, the
monitoring device decides not to generate the alert signal. In this manner,
the combination of plurality of sensor devices and monitoring device
provides a railway traffic monitoring system (referred to as monitoring
system) which ensures that the workers at the worksite are aware about any
vehicular movement, such as incoming railway traffic on the vehicular track.
[0020] The monitoring system including combination of sensor
devices and monitoring device as described in the present subject matter provides alert to the workers working at the worksite location in autonomous manner, without any manual intervention. Such monitoring system reduces possibility of accidents at the worksite location that is near the vehicular track and eliminates need for manual surveillance of the vehicular track. The monitoring system detects vehicular movement or incoming railway traffic

on the vehicular track that may be far away from the worksite location. In this manner, the monitoring system provides alert to the workers at the worksite in timely manner.
[0021] Further, the monitoring system operates on self-powered
mode without any external power supply. Due to simple and robust construction of the monitoring system, the monitoring system may be setup quickly and operates efficiently under extreme weather conditions at remote locations. In addition, since the monitoring system works on a separate network other than normal communication network, the monitoring system effectively provides the alert at remote location where mobile connectivity may be unreliable or not available.
[0022] Although the present subject matter is explained in
conjunction with a specific implementation pertaining to electrification of a running railway track. However, such implementation of the present subject matter should not be construed as a limitation. The monitoring system described in the present subject matter may be used for monitoring any incoming railway traffic on a vehicular track that is in vicinity of a worksite location.
[0023] Aspects of the present subject matter are further described in
conjunction with the accompanying figures FIGS. 1-3. The above examples are further described in conjunction with appended figures. It should be noted that the description and figures merely illustrate the principles of the present subject matter. It will thus be appreciated that various arrangements that embody the principles of the present subject matter, although not explicitly described or shown herein, may be devised from the description and are included within its scope. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific examples thereof, are intended to encompass equivalents thereof. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The same numbers are used throughout the figure to reference like features and components.

[0024] FIG. 1 illustrates an exemplary environment 100 in which a
monitoring system for monitoring vehicular movement on a vehicular track 102 is implemented, as per an example. In one example, the vehicular track 102 may be a railway track. Further, a worksite location 104, where an electrification work is being performed, is in vicinity of the vehicular track 102. For example, if a part of the vehicular track 102 which due to any failure or routine maintenance cycle may need electrification work which may corresponds to the worksite location 104. To this end, installation of overhead masts, overhead electrical equipment, power transmission lines, and the like, may be performed for such electrification of the vehicular track 102 at the worksite location 104.
[0025] The monitoring system for monitoring vehicular movement on
the vehicular track 102 may include a plurality of sensor devices 106-1, 106-2, 106-3, 106-4, and 106-5 (collectively referred to as sensor devices 106). Each of the sensor device of the plurality of sensor devices 106 may be a fusion sensor which includes a combination of sensors. Examples of sensors included in each of the sensor devices 106 may include, but are not limited to, noise sensor, vibration sensor, photoelectric sensor, accelerometer, pressure sensor, thermal sensor, and many more. Each of the sensor devices 106 may further include a transceiver for enabling communication of sensed data to remote locations.
[0026] As depicted in FIG. 1, the sensor devices 106 are positioned
along the vehicular track 102 away from the worksite location 104. In an example, the sensors devices 106 may be deployed in both directions, i.e., left (or upstream) as well as right (or downstream) of the worksite location 104 with at least 5Kms distance from the worksite location 104. For example, for worksite location 104, the sensor devices present to its left are 106-1, 106-2, and 106-3, and to its right are 106-4, and 106-5. It may be noted that, the number of sensor devices 106 indicated in FIG. 1 is exemplary and any number of sensor devices 106 may be deployed without deviating from the scope of the present subject matter. Moreover, the

sensor devices 106 either left or right of the worksite location 104 are also spaced apart from each other. In one example, a distance between consecutive sensor devices, such as sensor devices 106-1 and 106-2, or 106-2 and 106-3, may be about 5kms to about 10kms.
[0027] As described above, each of the sensor devices 106 may
include a combination of sensors, such as a piezoelectric sensor, a sound sensor, an accelerometer, a photoelectric sensor, and many more. Further, each of the sensors included in the sensor devices 106 may have its own sensing power to ascertain presence of the railway traffic on the vehicular track 102. For example, the piezoelectric sensor or vibration sensor may be configured to sense vibrations on the vehicular track 102 that may be caused due to the vehicular movement of the railway traffic over the vehicular track 102, thus enabling detection of movement of railway traffic on the vehicular track 102. The sound sensor may be configured to sense noise generated by the railway traffic on the vehicular track 102. Further the photoelectric sensor may be configured to sense the railway traffic on the vehicular track 102 by using a light transmitter. Moreover, the accelerometer as one of the sensors in the sensor devices 106 may be configured to sense acceleration of the railway traffic on the vehicular track 102. Such vibration value, noise value, photoelectric sensor value, and acceleration value may constitute the track parameters detected by the sensor devices 106 for corresponding location.
[0028] Once the sensor devices 106 sensed data, it may be
communicated to a remote location for further processing and to ascertain
a movement information of the railway traffic. For example, based on the
location covered by each sensor devices 106, the movement information
including direction of railway traffic, speed of the railway traffic, and a time
of response for evacuation of worksite location 104 may be determined.
[0029] Continuing further, the monitoring system may include a
monitoring device 108. As depicted in FIG. 1, the monitoring device 108 is deployed at or near the worksite location 104. The monitoring device 108

may be implemented as a combination of hardware and programming, for example, programmable instructions to implement a variety of functionalities of the monitoring device 108. For example, the programming for the monitoring device 108 may be executable instructions. Such instructions may be stored on a non-transitory machine-readable storage medium which may be coupled either directly or indirectly (for example, through networked means) to the monitoring device 108. In an example, the monitoring device 108 may include a processing resource, for example, either a single processor or a combination of multiple processors, to execute such instructions.
[0030] In operation, each of the sensor devices 106 deployed at a
specific location on the vehicular track 102 may monitor a corresponding
portion or location of the vehicular track 102 to detect changes in the
conditions of the vehicular track 102 due to the movement of any vehicular
traffic, or railway traffic thereon. For example, each of the sensor devices
106 may monitor track parameters within the corresponding portion of the
vehicular track 102 to detect the vehicular movement due to an incoming or
outgoing railway traffic on the vehicular track 102. In such a case, the
railway traffic may be due to a railway, a train, a locomotive or a wagon.
[0031] Examples of track parameters monitored by the sensor
devices 106 include, but are not limited to, vibration parameter indicating vibration in the vehicular track 102 due to the movement of the railway traffic, sound parameter indicating sound of the railway traffic detected by the noise sensor, photoelectric parameter indicating presence of the railway traffic on the vehicular track 102, pressure parameter indicating pressure applied by the railway traffic over the vehicular track 102, temperature parameter indicating variation in temperature due to movement of railway traffic over the vehicular track 102 and many more. To this end, each of the sensor devices 106 may sense track parameters for the corresponding portion or location of the vehicular track 102 which may be changed due to the movement of the railway traffic over the vehicular track 102. In an

example, in response to the movement of the railway traffic over the vehicular track 102, the track parameters increase from a first value to a second value. Such increment in track parameters from first value to second value may be monitored by the sensor devices 106 and are transmitted to monitoring device 108 to ascertain movement information of the railway traffic on the vehicular track.
[0032] Thereafter, the sensor devices 106 may transmit the
monitored track parameters to the monitoring device 108. In an example,
the sensor devices 106 may further include a transceiver module which
enables transmission of track parameters or other data to the monitoring
device 108. The transceiver module of the sensor devices 106 may
establish a communication channel between the sensor devices 106 and a
transceiver module of the monitoring device 108. For example, the
transceiver modules of the sensor devices 106 and the monitoring device
108 may enable wireless communication using wireless technology, such
as Bluetooth, Bluetooth Low Energy (BLE), Wi-Fi, Wi-Fi Direct, Near-Field
Communication (NFC), Zigbee, Z-wave, Low-power Wireless Personal
Area Network (LoWPAN), Long Term Evolution (LTE), General Packet
Radio Service (GPRS), Global System for Mobile communication (GSM),
LoRa (Long Range Wi-Fi), Long Range Wide access network (LoRaWAN).
Pursuant to present subject matter, the sensor devices 106 and the
monitoring device 108 may communicate using LoRa to ensure low power
consumption by the sensor devices 106 and the monitoring device 108.
[0033] In response, the monitoring device 108 receives the track
parameters from the sensor devices 106. In one example, the monitoring
device 108 receives the track parameters from the sensor devices 106
periodically, such as in every 1 minute, in every 5 minutes or every 10
minutes, or when the sensor devices 106 detects the vehicular movement.
[0034] Thereafter, the monitoring device 108 processes the track
parameters received from the sensor devices 106. In an example, the monitoring device 108 may process the track parameters associated with

the vehicular track 102 based on worksite parameters associated with the worksite location 104 to ascertain movement information of the railway vehicle over the vehicular track 102. Examples of worksite parameters include, but may not be limited to, geographical location of the worksite location 104, worksite location identifier, monitoring device identifier, locations of sensor devices 106, distance between sensor devices 106, sensor devices identifiers, demographic information associated with the worksite location, demographic information associated with the vehicular track, and identifier associated with user devices associated with the worksite location.
[0035] Based on the ascertained movement information, the
monitoring device 108 may determine if an alert is to be provided at the worksite location 104. For example, if the movement information depicts that the railway traffic is moving away from the worksite location 104 on the vehicular track 102 or when the railway traffic is moving through a different railway line, the alert may not be required.
[0036] On the other hand, when the monitoring device 108 ascertains
that the determined movement information depicts that railway traffic is moving towards the worksite location 104 on the same vehicular track 102, the monitoring device 108 may generate an alert signal in order to alert the workers to evacuate the worksite location 104. In another example, the monitoring device 108 may be coupled to an alarm system 110 at the worksite location 104. In an example, the alarm system 110 may be a loudspeaker, a light indicator, a display device, or combination thereof. The monitoring device 108 may transmit the generated alert signal to the alarm system 110 for triggering the alarm system 110. Once the alarm system 110 is triggered, the alarm system 110 may provide the alert to the workers at the worksite location 104. In such a case, the alarm system 110 may receive the alert signal from the monitoring device 108 and accordingly provide the alert to the workers of the worksite location 104 based on the type of component included in the alarm system. For example, an audio message

for alerting is provided for a siren or a loudspeaker, a light indicating alert is switched on for a light indicator, and a time of response or a time of evacuation is displayed for a display device. In another example, the monitoring device 108 may be in communication with user devices of the workers and sends an alert message or indication directly to each of the user devices. In this manner, safety of operation at the worksite location 104 may be ensured.
[0037] An example procedure to be implemented by the monitoring
device 108 to process the track parameters to ascertain the movement information and determining the need to generate the alert signal based on the ascertained movement information is explained below. For example, as depicted in FIG. 1, if railway traffic approaches worksite location 104 from left side, then initially it passes through the first sensor device 106-1. In response to the movement of the railway traffic over the vehicular track 102, the conditional parameters, such as track parameters associated with the vehicular track 102 changes and the first sensor device 106-1 monitors those changes and transmits the sensed track parameters to the monitoring device 108. The monitoring device 108 receives the track parameters and processes it with the worksite parameters to identify the presence of the railway vehicle at the location where the first sensor device 106-1 is positioned. However, such identification of presence of railway vehicle at location of the first sensor device 106-1 may not be enough for the monitoring device 108 to identify the direction, speed, and a time of arrival of the railway traffic to the worksite location 104. Since, the monitoring device 108 by way of worksite parameters knows location of sensor devices 106 and other route related information, it waits for the track parameters from the second sensor devices, i.e., 106-2.
[0038] To this end, the monitoring device 108 waits for receiving track
parameters from the second sensor device 106-2. Once the railway vehicle passes through the second sensor device 106-2, the sensor device 106-2 monitors the change in track conditions and transmit the track parameters

indicating those conditional changes in the vehicular track 102 to the
monitoring device 108. Now, the monitoring device 108 processes received
track parameters from second sensor device 106-2 to ascertain movement
information for the railway vehicle. For example, with the worksite
parameters available, the monitoring device 108 already know the locations
of sensor devises 106, distance of sensor devices 106 from the worksite
location, and distance between the different sensor devices 106.
[0039] By ascertaining that the similar changes have been reflected
in both the track parameters received from first sensor device 106-1 and the second sensor device 106-2, the monitoring device 108 confirms or set the direction of the railway vehicle, i.e., the railway vehicle is approaching towards worksite location 104. Further, by knowing distance between different sensor devices 106, the monitoring device 108 calculates or determines the speed of the railway traffic. Subsequently based on the calculated speed and the distance between the second sensor device 106-2 and the worksite location 104, it calculates the time of arrival (or the time of response) of the railway traffic to the worksite location 104. As depicted in FIG. 1, after passing second sensor device 106-2, there are two possible paths on which the railway vehicle may go. For example, if railway traffic goes straight (referred to as path 1) then it goes in the direction of worksite location 104, on the other hand, if it turns on the other path (referred to as path 2), then it may go to a different railway line.
[0040] Since the monitoring device 108 knows worksite parameters,
it also knows about the location of third sensor device 106-3 and information regarding track routes. Therefore, the monitoring device 108 waits for the track parameters from the third sensor device 106-3 to make a final decision regarding generating the alert signal. In an example, if train chooses path 1 then the track parameters sensed by the third sensor device 106-3 are transmitted by the third sensor device 106-3 to the monitoring device 108. The monitoring device 108 in response, processes the received track parameters with the worksite parameters to ascertain movement

information. For example, the monitoring device 108 may update the speed based on the time lapsed to reach from second sensor device 106-2 to third sensor device 106-3 and finally determines time of arrival of the railway vehicle to the worksite location 104. On the other hand, if railway vehicle chooses path 2, then there are no changes being recorded in track parameters sensed by the third sensor device 106-3 and monitoring device 108 after a period of time drops the collected information and assumes that the railway traffic may have chosen different path.
[0041] Thereafter, based on the determined movement information,
the monitoring device 108 generates the alert signal. In one example, the alert signal may include time of arrival of railway vehicle or time or response to evacuate the worksite location 104. In this way, the monitoring device 108 monitors the movement of the railway traffic over the vehicular track 102 and alert the workers at the worksite location 104 to evacuate the worksite location 104. It may be noted that similar monitoring of track parameters is also performed by the sensor devices present on right (i.e., 106-4, 106-5) of the worksite location 104 and transmitted to monitoring device 108 to process the track parameters and generate the alert signal to alert the workers at the worksite location 104.
[0042] FIG. 2 illustrates a detailed block diagram of a monitoring
device, such as the monitoring device 108, for processing track parameters indicating vehicular movement on a vehicular track, such as vehicular track 102, and alerting workers at a worksite, such as worksite location 104, as per an example. The monitoring device 108 may be any processor enabled device which performs certain specific functions. The monitoring device 108 may be in communication with a plurality of sensor devices, such as the sensor devices 106. The monitoring device 108 may further be in communication with user devices (not shown in FIG. 2) which may be carried by workers at the worksite location 104, or supervisor of the worksite location 104.

[0043] In an example scenario, as may be depicted in FIG. 1, the
worksite location 104 may be in vicinity of the vehicular track 102 or a part of the vehicular track 102. Further, a plurality of sensor devices such as the sensor devices 106 may be deployed or positioned along the vehicular track 102. In an example, the sensor devices 106 are installed on a raised platform at corresponding locations. In another example, the sensor devices 106 may be positioned on poles which may be running on both sides along the vehicular track 102. Further, the monitoring device 108 may be deployed in vicinity of the worksite location 104. In an example, the monitoring device 108 may be either a standalone device or in communication with other systems (not shown in FIG. 2) over a communication network. The present approaches may also be implemented in other types of the system without deviating from the scope of the present subject matter.
[0044] The monitoring device 108 may include interface(s) 202,
processor(s) 204, and memory(s) 206. The interface(s) 202 may allow the connection or coupling of the monitoring device 108 with one or more other devices, through a wired (e.g., Local Area Network, i.e., LAN) connection or through a wireless connection (e.g., Bluetooth, Wi-Fi). The interface(s) 202 may also enable intercommunication between different logical as well as hardware components of the monitoring device 108.
[0045] The processor(s) 204 may be implemented as a combination
of hardware and programming, for example, programmable instructions to implement a variety of functionalities. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor(s) 204 may be executable instructions. Such instructions may be stored on a non-transitory machine-readable storage medium which may be coupled either directly with the monitoring device 108 or indirectly (for example, through networked means). In an example, the processor(s) 204 may include a processing resource, for example, either a single processor or a combination of multiple processors, to execute such instructions. In the

present examples, the non-transitory machine-readable storage medium may store instructions that, when executed by the processor(s) 204, implement various functionalities.
[0046] The memory(s) 206 may be any computer-readable medium
known in the art including, for example, volatile memory, such as Static Random-Access Memory (SRAM) and Dynamic Random-Access Memory (DRAM), and/or non-volatile memory, such as Read-Only Memory (ROM), Erasable Programmable ROMs (EPROMs), flash memories, hard disks, optical disks, and magnetic tapes.
[0047] The monitoring device 108 may further include module(s) 208
and data 210. The module(s) 208 may be implemented as a combination of hardware and programming logic (for example, programmable instructions) to implement one or more functionalities of the module(s) 208. In examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the module(s) 208 may be executable instructions. Such instructions in turn may be stored on a non-transitory machine-readable storage medium which may be coupled either directly with the monitoring device 108 or indirectly (for example, through networked means). In an example, the module(s) 208 may include a processing resource (for example, either a single processor or a combination of multiple processors), to execute such instructions. In the present examples, the processor-readable storage medium may store instructions that, when executed by the processing resource, implement module(s) 208. In other examples, module(s) 208 may be implemented as electronic circuitry.
[0048] The module(s) 208 may include a transceiver module 212 for
enabling communication between the monitoring device 108 and other devices, such as the sensor devices 106, an analysis module 214 for processing track parameters to ascertain movement information and alerting the workers at the worksite location 104 and other module(s) 216. The other module(s) 216 may further implement functionalities that

supplement applications or functions performed by the monitoring device 108 or any of the module(s) 208.
[0049] The data 210 includes data that is either stored or generated
as a result of functionalities implemented by the module(s) 208 or the monitoring device 108. It may be noted that information stored and available in the data 210 may be utilized by the module(s) 208 for processing track parameters to ascertain movement information and alerting the workers on the worksite location 104. The data 210 may include track parameters 218, worksite parameters 220, movement information 222, alert signal 224 and other data 226. The track parameters 218 may be indicative of the change in track conditions due to the movement of the railway traffic on the vehicular track 102, worksite parameters 220 may be indicative of location, demographic and identity related information of the worksite location 104 and the plurality of sensor devices 106, movement information 222 may indicate direction, speed, and a time of response for evacuating the worksite location 104, and the alert signal 224 may include information regarding time of response or a time of arrival of the railway traffic on the worksite location 104.
[0050] In operation, once the sensor devices 106 are set-up along
the vehicular track 102 at specified location, the sensor devices 106 may now monitor the corresponding locations or portions of the vehicular track 102 to detect any vehicular movement or railway traffic thereon. The sensor devices 106 may monitor the track parameters 218 corresponding to the vehicular track 102 to detect the railway traffic on the vehicular track 102. Examples of track parameters 218 include, but are not limited to, vibration parameter indicating vibration in the vehicular track 102 due to the movement of the railway traffic, sound parameter indicating sound of the railway traffic detected by the noise sensor, photoelectric parameter indicating presence of the railway traffic on the vehicular track 102, pressure parameter indicating pressure applied by the railway traffic over the vehicular track 102, temperature parameter indicating variation in

temperature due to movement of railway traffic over the vehicular track 102. In an example, in response to the movement of the railway traffic over the vehicular track 102, the track parameters increase from a first value to a second value. Such increment in track parameters from first value to second value may be monitored by the sensor devices 106 and are transmitted to monitoring device 108 to ascertain movement information of the railway traffic on the vehicular track.
[0051] Thereafter, the monitored track parameters are transmitted to
the monitoring device 108. In an example, the sensor devices 106 may be configured to transmit the track parameters 218 to the monitoring device 108 based on the identifier associated with the monitoring device 108. In response, the transceiver module 212 of the monitoring device 108 may receive the track parameters 218 from each of the sensor devices 106. For example, the transceiver module 212 of the monitoring device 108 receives the track parameters 218 from the sensor devices 106 periodically, such as in every 1 minute, in every 5 minutes or every 10 minutes, or when the sensor devices 106 detects the vehicular movement. The transceiver module 212 of the monitoring device 108 may receive the track parameters 218 from each of the sensor devices 106, for example, via LoRA technology. The monitoring device 108 may store the track parameters received from the sensor devices 106 as the track parameters 218.
[0052] Once received, the analysis module 214 of the monitoring
device 108 may process the track parameters 218 with the worksite information 222 in real-time to ascertain movement information 222 of the railway traffic. Examples of worksite parameters 220 include, but may not be limited to, geographical location of the worksite, worksite location identifier, monitoring device identifier, locations of sensor devices 106, distance between sensor devices 106, sensor devices identifiers, demographic information associated with the worksite location 104, demographic information associated with the vehicular track 102, and identifier associated with user devices associated with the worksite location

104. For example, the monitoring device 108 may interface with a user to obtain the worksite parameters 220 or obtain the worksite parameters 220 automatically, for example, using location services.
[0053] Based on the processing, the analysis module 214 may
ascertain movement information 222 including, for example, presence of the
railway traffic, direction of the railway traffic, speed of the railway traffic,
distance between the railway traffic and the worksite 104, time of arrival of
the railway traffic at the worksite location 104, and predicted route of the
railway traffic. Thereafter, based on the ascertained movement information,
the analysis module 214 generate the alert signal 224 for alerting workers
working at the worksite location 104 to evacuate the worksite location 104.
In an example, if the movement information 222 indicates that the railway
vehicle is approaching worksite location 104, then the alert signal 224 is
generated. On contrary to this, if the movement information 222 indicates
that the railway vehicle is either moving away from the worksite location 104
or moving on different railway line, then no alert signal 224 is generated.
[0054] On ascertaining that the alert has to be provided at the
worksite location 104, the analysis module 214 of the monitoring device 108 may generate the alert for the worksite location 104. In another example, the monitoring device 108 may be coupled to an alarm system (such as the alarm system 110) at the worksite location 104. In such a case, the analysis module 214 may transmit the alert signal 224 to the alarm system 110 to generate a trigger for the alarm system 110. After receiving the trigger, the alarm system 110 may provide the alert to the workers on the worksite. The alarm system 110 may include, for example, a siren or a hooter, a flashlight, an emergency light, a display device, or a combination thereof. Specifically, the alarm system 110 may activate any of the above disclosed means to provide the alert to the workers. In an example, the siren or loudspeaker may be activated for a pre-defined time period, such as 30 seconds, 1 min, 5 minutes, or until the passage of the railway traffic from the vehicular track 102 under supervision is cleared.

[0055] In an example, the analysis module 214 may also determine
a response time for evacuating the worksite location 104 or a time of arrival of the railway traffic on the worksite location 104. In such a case, the display associated with the alarm system 110 may display the response time or the time of arrival.
[0056] In another example, the monitoring device 108 may store the
track parameters 218 and/or the worksite information 220 at a remote storage associated with the monitoring device 108. The monitoring device 108 may then provide interface for accessing the track parameters 218 and/or the worksite information 220 through web platforms. The monitoring device 108 may further include a prediction module for processing the track parameters 218 and/or the worksite information 220 to predict future railway traffic flow on the vehicular track 102, railway traffic flow on a track associated with the vehicular track 102, and visualize future occurrences of railway traffic on the vehicular track 102. The monitoring device 108 may also aid planning, management and execution of tasks or activity at the worksite location 104, based on the track parameters 218 and the worksite information 220.
[0057] FIG. 3 illustrates a method 300 for monitoring vehicular
movement on a vehicular track and alerting workers at a worksite, as per an example. Although the method 300 may be implemented by a variety of devices, for the ease of explanation, the present description of the example method 300 is provided in reference to the above-described monitoring device 108 which is in communication with the plurality of sensor devices 106. The order in which the method 300 is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method 300, or an alternative method.
[0058] It may be understood that blocks of the method 300 may be
executed based on instructions stored in a non-transitory computer-readable medium, as will be readily understood. The non-transitory

computer-readable medium may include, for example, digital memories, magnetic storage media, such as magnetic disks and magnetic tapes, hard drives, or optically readable digital data storage media.
[0059] Referring to FIG. 3, at block 302, worksite parameter
indicative of the location, demographic and identity related information of
the worksite location and the plurality of sensor devices is obtained. For
example, the monitoring device 108 may interface with a user to obtain the
worksite parameters 220 or obtain the worksite parameters 220
automatically, for example, using location services. The worksite location
104 may be in vicinity of the vehicular track 102 or a part of the vehicular
track 102. In an example, the vehicular track 102 may be a railway track.
[0060] At block 304, track parameters associated with the vehicular
track are received. In an example, the track parameters are indicative of the changes in the track conditions due to the movement of the railway traffic on the vehicular track. For example, the transceiver module 212 of the monitoring device 108 receives the track parameters 218 monitored by the plurality of sensor devices 106. In an example, the sensor devices 106 may be positioned along the vehicular track 102 away from the worksite location 104, wherein the sensor devices 106 monitor track parameters 218 for corresponding location. The sensor devices 106 may detect the track parameters 218 for the vehicular track 102 to detect any vehicular movement or railway traffic thereon. The sensor devices 106 may transmit the track parameters 218, periodically or on detecting the railway traffic, to the monitoring device 108 deployed at the worksite location 104. In one example, the sensor devices 106 and the monitoring device 108 may employ low power communication technology, such as LoRaWAN or LoWPAN, to communicate. Thus, power consumption of the sensor devices 106 and the monitoring device 108 may be optimized making it viable for remote locations.
[0061] At block 306, the track parameters are processed using the
worksite parameters to ascertain movement information of the railway traffic

on the vehicular track. For example, the analysis module 214 of the monitoring device 108 may process the track parameters 218 using the worksite parameters 220 to ascertain the movement information 222 of the railway traffic on the vehicular track 102. Based on the processing, the analysis module 214 may ascertain movement information 222 including, for example, presence of the railway traffic, direction of the railway traffic, speed of the railway traffic, distance between the railway traffic and the worksite location 104, time of arrival of the railway traffic at the worksite location 104, and predicted route of the railway traffic.
[0062] At block 308, an alert signal for alerting workers to evacuate
the worksite location is generated based on the ascertained movement information. For example, when the ascertained movement information 222 indicate that the railway traffic on the vehicular track 102 is approaching towards worksite location 104, the analysis module 214 of the monitoring device 108 may generate the alert signal 224 for alerting workers to evacuate the worksite location 104. In another example, the monitoring device 108 may be coupled to an alarm system, such as alarm system 110 on the worksite location 104. In such a case, the alarm system 110 may receive the alert signal 224 from the monitoring device 108 and accordingly provide the alert to the workers of the worksite location 104 based on the type of component included in the alarm system. For example, an audio message for alerting is provided for a siren or a loudspeaker, a light indicating alert is switched on for a light indicator, and a time of response or a time of evacuation is displayed for a display device. In another example, the monitoring device 108 may be in communication with user devices of the workers and sends an alert message or indication directly to each of the user devices. In this manner, safety of operation at the worksite location 104 may be ensured.

been described in language specific to structural features and/or methods, it is to be understood that the appended claims are not necessarily limited

to the specific features or methods described. Rather, the specific features and methods are disclosed and explained as implementations of the present disclosure.
