TECHNICAL FIELD
[0001] The present disclosure relates to the field of communication systems. More particularly, the present disclosure relates to a train communication system suitable for providing real-time information to various users of the proposed system.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In recent years, needs have grown for the passenger information services inside a train. At present, the trains are not equipped with a suitable communication channel between a driver of the train and fellow passengers inside the train coaches. If the train is delayed or late due to some work or other technical difficulties, the passengers are not aware about the issue. This situation creates a sense of frustration and anger in the passengers as they are not aware about the situation.
[0004] Existing solutions for providing a proper communication system in trains are based on systems having a microphone at driver’s end inside the driver cabin and speakers provided at designated place inside train coaches. In this type of system, only the driver can transmit the message to the passengers using the microphone and speakers. This type of system provides a communication channel but is limited only in this manner and can only provide messages to all passengers simultaneously. There are very high chances that one/ more passengers might miss the message altogether due to high ambient noise common in trains that may make the message inaudible. Besides, there may be situations requiring other entities besides the train driver to convey messages to passengers. Such entities could be, for instance the train guard or a train superintendent based at an approaching station (station master, for instant). Further, some messages may be meant for some passengers and not for others. Existing systems cannot cater to these situations.
[0005] Hence there is a need in the art for a system that can provide messages to recipients in a very noisy environment, can enable messages to be provided to specific recipients, and can enable more than one senders as required to send messages.
[0006] As used in the description herein and throughout the claims that follow, the meaning of “a,” “an,” and “the” includes plural reference unless the context clearly dictates otherwise. Also, as used in the description herein, the meaning of “in” includes “in” and “on” unless the context clearly dictates otherwise.
[0007] Groupings of alternative elements or embodiments of the invention disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all groups used in the appended claims.

[0041] The present disclosure relates to the field of communication systems. More particularly, the present disclosure relates to a train communication system for providing information pertaining to operation of a train to various persons in the train in an appropriate manner and in real-time.
[0042] In an aspect, proposed disclosure elaborates upon a communication system for a train. The system can include one or more processors coupled with a memory, the memory storing instructions executable by the one or more processors to: receive, from a first computing device associated with a first entity , a first message to be communicated to one or more communication devices associated with one or more second entities, and append the message with unique identifications (UIDs) of the one or more communication devices; convert the received first message into one or more second messages in formats suitable for transmission to the one or more communication devices ,each of the one or more second messages carrying UID of a communication device the each second message is directed towards; and transmit the one or more second messages to the one or more communication devices based upon UIDs carried in the one or more second messages.
[0043] In another aspect, the first entity can be any of driver of the train, guard of the train and station master monitoring the train and the second entity can be any of the train, a coach in the train, a seat row in the train and a seat in the train.

[0045] In an aspect, one or more of the first computing devices can function as one or more of the communication devices to enable communication among one or more of the first entities.
[0046] In another aspect, the one or more processors can include one or more Arduino Uno chipset microcontrollers.
[0047] In yet another aspect, the system can be configured in any or a combination of a server and cloud, and the computing devices can include any or a combination of a personal computer, a laptop, a tablet, and a mobile device.
[0048] In an aspect, receipt of the first message and transmission of the one or more second messages can use any or a combination of wired and wireless means.
[0049] In another aspect, present disclosure elaborates upon a method of communication for a train. The method can include the steps of: receiving, at a computing system, from a first computing device associated with a first entity, a first message to be communicated to one or more communication devices associated with one or more second entities, and appending, using the computing system, the message with unique identifications (UIDs) of the one or more communication devices.
[0050] The method can further include the step of converting, using the computing system, the received first message into one or more second messages in formats suitable for transmission to the one or more communication devices, each of the one or more second messages carrying UID of a communication device the each second message is directed towards; and transmitting, using the computing system, the one or more second messages to the one or more communication devices based upon UIDs carried in the one or more second messages.
[0051] FIGs. 1A to 1C illustrate an overall architecture of the proposed system to elaborate upon its working in accordance with an exemplary embodiment of the present disclosure.
[0052] As illustrated in FIG. 1A proposed system 100 can enable a first entity (for instance a train driver 102) to provide a message shown as M1 using his computing device 104 that is to be communicated to computing devices associated with one or more second entities ( for instance, one or more chairs, interchangeably termed as seats herein, in the train ).
[0053] For the purpose, chairs of the train can have associated communication devices shown as 106-1, 106-2…106-N ( one for each chair, collectively termed as 106 ) and each such communication device can have a unique identification (UID) that can be mapped, for example, to the chairs shown as C1, C2, C3…Cn.
[0054] In an exemplary embodiment, the chair numbers can in turn be mapped to corresponding passengers occupying each chair by operatively connecting the proposed system to a reservation system. In this manner, message to be sent a passenger can be sent to chair occupied by the passenger.
[0055] Various messages (such as M1) can carry information pertaining to a train for which the proposed system 100 is being used. System 100 can be configured within the train itself, or can be operatively connected to it, or some components can be in the train while others can be in operative connection with it using means well known in the art. Such means may well be provided as well by existing communication system of a train network in which the train is operating.
[0056] Proposed system 100 can receive a message, convert the received message into one or more other messages in formats suitable for transmission to one or more communication devices, can provide to each of the one or more messages UID of the communication device it is directed towards, and can accordingly transmit the message to the right communication device and accordingly to the right chair, and , as elaborated above , by appropriate mapping to the right passenger.
[0057] In an aspect, communication devices 106 can be display devices. Or some of them can be a loudspeaker, and some others can be both. Still some others can carry displays for the visually impaired.
[0058] In an exemplary embodiment, message M1 can carry information pertaining to the train relevant to all passengers. For example, message M1 can indicate approaching station, delay in train if any, train speed etc. and can be provided by train driver as an audio message using his computing device CD 104.
[0059] The passengers may be occupying chairs C1, C2 and C3. CD 106-1 associated with C1 may be a normal display device, similarly CD 106-2 may be a speaker and CD 106-3 may be a display for the visually impaired.
[0060] As shown in FIG. 1A, proposed system can convert can convert M1 into three messages M1d, M1v and M1b.
[0061] Format of M1d can be suitable for display on CD 106-1, and proposed system can transmit it to CD 106-1 where passenger in chair C1 can see it. Similarly, format of M1v can be suitable for speaker of CD 106-2, and proposed system can transmit M1v to CD 106-2 wherein can be announced over speaker therein. Format of M1b can be suitable for display CD 106-3 for visually impaired, and proposed system can transmit M1b to CD 106-3 wherein I can be seen by a visually impaired passenger sitting in chair C3 associated with CD 106-3.
[0062] In this manner, as can be understood, proposed system can convert a message into different messages of different formats suitable to communication devices where the message is to be sent so that the message can be properly seen/heard by all concerned.
[0063] In a similar manner, two or more formats may be required for one communication device (for instance, a communication device can have a speaker as well as a display), wherein the message sent to such a communication device can be a combination of both formats ( or be a combination of two messages, each of one format).
[0064] As can be readily understood, all communication devices associated with all chairs can have displays and an audio announcement can be displayed on such devices thereby eliminating problem of bad/no communication of information due high noise. Further, each coach can have one (or more) high level loudspeakers that can announce important announcements all through the coach.
[0065] In this manner, proposed system can transmit a message to all chairs/passengers using broadcast method.
[0066] In another exemplary embodiment, a train superintendent 108 can, using his computing device 110, provide a message M2 for chair C2 only ( for associated passenger P2, for example, such information being provided by a reservation system operatively connected to the proposed system) as shown in FIG. 1B. Proposed system can receive message M2, determine that it is meant only for chair C2, convert message M2 into format M2v suitable for communication device CD106-2 of C2, and can transmit message M2v to communication device of 106-2 of Chair C2 where passenger P2 can receive it.
[0067] In yet another exemplary embodiment, proposed system 100 can enable a train guard 112 to, using his computing device 114, generate a message M3 for only some chairs (say chairs C1 and C3 as shown in FIG.1C). Proposed system 100 can receive message M3, determine that it is meant for C1 and C3, convert message M3 into two messages M3 d and M3v wherein M3d is in format suitable for CD 106-1 of chair C1 and M3b is in format suitable for CD 106-3 of C3, and can transmit these messages to corresponding communication devices for use by associated passengers.
[0068] In an exemplary embodiment, passengers P1 and P3 in chairs C1 and C3 may have elected to receive message M3 during a prior procedure (for instance, during making a reservation). In this manner, proposed system can transmit a message to those passengers / communication devices interested in receiving the message, using a multicast method.
[0069] It can be understood that various computing devices can as well function as communication devices. In this manner, two -communication amongst the first entities (for instance train driver 102, train superintendent 108 and train guard 112) can be achieved.
[0070] For instance, train superintendent 108 may send a message to train driver 102 (or vice versa), or train superintendent 108 can send a message to train guard 112 (or vice versa), or train driver 102 can send a message to train guard 112 (or vice versa). Messages can be provided to corresponding computing devices that can be considered as communication devices for such purposes.
[0071] Various communication devices can be configured as display devices. Proposed system can convert messages being received into those of different formats necessary for displaying on such display devices. Hence, various messages can be displayed on the corresponding display devices. This can avoid / eliminate the problem of messages not being heard due to high noise levels in the train. For instance, train driver 102 can speak using his computing device 104 and this verbal message M1 can be received by system 100 and converted into format suitable for display on communication devices 106-1, 106-2 etc.
[0072] In an aspect, a communication devices 106 can include both a display as well as a loudspeaker and messages received can be converted into both formats as required by the proposed system. For instance, train superintendent 108 may provide message M2 in text format (for instance, by means of a keyboard on computing device 110) for communication device 106-2 of passenger P2. Proposed system 100 may receive message M2, determine that communication device 106-2 has a display as well as a loudspeaker, can create a copy of message M2, can display the original M2 on display of communication device 106-2, can convert the copy of message M2 into an audio format message (say Ma) and can play Ma on speaker of communication device 106-2. All such embodiments and their various combinations are fully a part of the present disclosure.
[0073] In this manner proposed system can communicate information pertaining to a train without being affected by noise, can enable specificity of message delivery, and can enable any of a train driver, a train guard and a train superintendent to communicate information in real-time to one or more passengers of the train. External communication systems (for example a train movement information system) as well as other systems ( a train reservation system, for instance ) can be operatively connected to proposed system and provide relevant information to it as needed.
[0074] FIG. 1D illustrates an example of working of the proposed system in a train in accordance with an exemplary embodiment of the present disclosure.
[0075] As illustrated, the proposed system can include a number of displays provided at various places inside a train. As shown in figure, a display 122-1 can be located inside a train engine 120 (also referred to as driver cabin 120) and can display messages/information received by a driver 124 (also referred to as train driver 124). Further, a plurality of displays (collectively referred as displays 122-2) can be provided at various locations inside the train coaches 126 of the train. The displays 122-2 can display messages /information for different passengers (either individual messages or collectively to all, as elaborated above, as well as a means of entertainment for the passengers of train coaches 126. The proposed system can be incorporated with an existing communication system 128 of the train provided in the driver cabin 120 for connecting the train driver 124 to a railway communication and signal system.
[0076] In an embodiment, the displays 122-2 can be provided on the gates of the train as well as on the back side of the seats of each of the train coaches 126.
[0077] FIG. 2A illustrates exemplary functional units of the proposed system in accordance with an exemplary embodiment of the present disclosure.
[0078] In one exemplary embodiment, proposed system 100 may include one or more processors 202, one or more input/output (I/O) interfaces 204, and a memory 206. The processor(s) 202 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, and/or any devices that manipulate signals based on operational instructions. Among other capabilities, the processor(s) 202 are configured to fetch and execute computer-readable instructions stored in the memory 206.
[0079] The I/O interfaces 204 may include a variety of software and hardware interfaces, for example, a web interface, a graphical user interface (GUI), and the like. The I/O interfaces 204 may allow the proposed system 100 to interact with a user directly or through the appropriately configured client devices (for instance computing devices CD 104 as illustrated in FIG.1). Further, the I/O interfaces 204 may enable proposed system 100 to communicate with other computing devices, such as web servers and external data servers (not shown). The I/O interfaces 204 can facilitate multiple communications within a wide variety of networks and protocol types, including wired networks, for example, LAN, cable, etc., and wireless networks, such as WLAN, cellular, or satellite. The I/O interfaces 204 may include one or more ports for connecting a number of devices to one another or to another server.
[0080] The memory 206 may include 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 ROM, flash memories, hard disks, optical disks, and magnetic tapes. The memory 206 may include modules, routines, programs, objects, components, data structures, etc., which perform particular tasks or implement particular abstract data types.
[0081] In an aspect, proposed system 100 can include a receiver 208, a convertor 210, a transmitter 212 and a database 214.
[0082] In an aspect, database 216 can store all pertinent data for operation of the proposed system. In an exemplary embodiment, database 216 can store for each train data such as unique identification (UID) for each communication device (CD) in the train. The UID can comprise in turn, for instance, train number, coach number and chair number so that the UID can be easily mapped to a chair. It can readily be appreciated that such CDs can as well be configured, in alternate exemplary embodiments for a complete coach/train compartment, for a train driver cabin, a train guard cabin, and a train superintendent’s room (that can be at a station or at a central monitoring place remote from a train configured with proposed system) and can themselves be computing devices.
Receiver 208
[0083] In an exemplary embodiment, receiver 208 can be any device, having a circuitry as further elaborated and a housing as appropriate. Or receiver 208 can be configured in a housing having other components of system 100 as well.
[0084] In another exemplary embodiment, receiver 208 can receive a message (for instance message M1) from a first entity (for instance train driver 102) desirous of sending the message to one or more second entities ( for instance chairs C1, C2…Cn). The first entity can have an associated computing device (such as CD 104) that it can use for providing the message (for instance message M1) to the proposed system. Proposed system 100 can enable necessary user interfaces ( using interfaces 206) on CD 104 of train driver 102 and using such interfaces train driver 102 can select chairs (second entities) to which message M1 can be sent. Such chairs can be represented, for instance, by their chair numbers and using this information proposed system can retrieve from database 216 UIDs of associated communication devices 106 of corresponding chairs.
[0085] In an exemplary embodiment, the interface can enable train driver 102 to send message M1 to all communication devices associated with different locations (or, for instance, all the communication devices of the train in which proposed system is configured, which may also include, for instance, a communication device in a coach, and another in train guard’s cabin.).
[0086] Accordingly, receiver 208 can append to message M1 UIDs of all communication devices to which message M1 is to be sent, and can provide message M1 with such UIDs to converter 210.
[0087] It can be appreciated that message M1 can be indifferent formats depending upon first entity 102 and its computing device 104. For instance, one CD 104 can enable a first entity to provide a text message, while another CD 104 can enable another first entity to provide a voice message.
[0088] In an aspect, receiver 208 can, based upon instructions stored in memory 206, enable the one or more processors 202 of system 100 to perform different functions of receiver 208 as elaborated above.
[0089] In an aspect, receiver 208 can, based upon instructions stored in memory 206, enable the one or more processors 202 of system 100 to perform different functions of receiver 208 as elaborated above. In an exemplary embodiment, receiver 208 can include one or more processors dedicatedly used to perform functionalities of receiver 208 as elaborated.
Converter 210
[0090] In an aspect converter 210 can, based upon instructions stored in memory 206, enable the one or more processors 202 of system 100 to convert the received first message into one or more second messages in formats suitable for transmission to the one or more communication devices, each of the one or more second messages carrying UID of a communication device the each second message is directed towards.
[0091] In an exemplary embodiment, converter 210 can convert the received one message M1 (first message) with a least one UID as elaborated above and make copies of message M1 (such copies being termed as second messages), each with one UID of the communication device it is to be sent to. Further, converter 210 can enable retrieval, from database 216 of format(s) required by a communication device and can convert corresponding message into the format(s) required.
[0092] For instance, converter 210 can determine that message M1 (or a copy of message M1, the two terms used interchangeably herein) has to be sent to a communication device 106-1 of chair C1 that has both a speaker and a display, while message M1 as provided by its first entity is in a text format. Converter 210 can accordingly convert message M1 both into a voice format (say M1v) as well as a display format (say M1d).
[0093] In a similar manner, converter 210 can convert each copy of message M1 per formats required by communication device to which it is to be sent. Further, converter 210 can append to each such converted message UID of the communication device it is to be sent to and provide such converted messages with appended UIDs to transmitter 212.
[0094] In an aspect, converter 210 can, based upon instructions stored in memory 206, enable the one or more processors 202 of system 100 to perform different functions of converter 210 as elaborated above. In an exemplary embodiment, converter 210 can include one or more processors dedicatedly used to perform functionalities of converter 210 as elaborated.
Transmitter 212
[0095] In an aspect, transmitter 212 can send the one or more second messages to the one or more communication devices based upon UIDs carried in the one or more second messages.
[0096] As can be readily understood from above, a voice based message M1 can be converted to a text based message and provided to a communication device having only a display. A text based message M2 can be converted to a voice based message as well as a text based message and can be provided to a communication device with both such abilities. This can eliminate problems associated with noise in trains since messages can be visually displayed on various communication device having displays.
[0097] In an exemplary embodiment, transmitter 212 can include one or more processors dedicatedly used to perform functionalities of transmitter 212 as elaborated above
[0098] In this manner, based upon UID of each communication device, a message can be addressed to specific communication devices and their associated chairs /locations (second entities) and various ways of transmitting a message such as unicast, broadcast and multicast can be deployed.
[0099] In an aspect, transmitter 212 can, based upon instructions stored in memory 206, enable the one or more processors 202 of system 100 to perform different functions of transmitter 212 as elaborated above. In an exemplary embodiment, transmitter 212 can include one or more processors dedicatedly used to perform functionalities of transmitter 212 as elaborated.
[00100] In an exemplary embodiment, proposed system can be operatively connected with other systems for various purposes. For instance a passenger while booking his ticket may have indicated that he requires a message indicating which platform the train is arriving on ( a his destination) so that he may inform his relatives accordingly.
