, Description:TECHNICAL FIELD:
Present disclosure relates in general to a field of automobiles. Particularly, but not exclusively, the present disclosure relates industrial locomotives. Further embodiments of the present disclosure disclose a system and method for remote speed evaluation of a locomotive in an industrial zone.
BACKGROUND OF THE DISCLOSURE:
Locomotive is a complex system employed in many industrial and processing zones including metallurgical industries, manufacturing industries and the like for transporting the material. Locomotives may be used in various application including passenger hauling, goods hauling and also locomotives may be used within industries to haul materials from one location to other location within the industry. Locomotives in general include numerous subsystems, each subsystem interdependent on other subsystems. An operator aboard a locomotive applies tractive and braking effort to control the speed of the locomotive and its load of railcars to assure safe and timely arrival at the desired destination. Speed control must also be exercised to maintain in-train forces within acceptable limits, thereby avoiding excessive coupler forces and the possibility of a train break. To perform this function and comply with prescribed operating speeds that may vary with the train's location on the track, the operator generally must have extensive experience operating the locomotive over the specified terrain with various railcars.
Such small industrial locomotives are typically used to move one to several rail cars in and around a factory, a mine, a small rail yard, a shipping hub, and the like. These are typically small locomotives with two or more axles attached directly to the locomotive frame or by means of swiveling truck assemblies that are attached to the locomotive car body. For larger industrial applications new switcher locomotives or line-haul locomotives are often employed. Railcar movers are another alternative for moving rail cars about the industry yard. These are road-rail vehicles capable of traveling on both roads and rail tracks. They are fitted with couplers for moving small numbers of railroad cars around in a rail siding or small yard. These locomotives used in the industry are generally of unmanned type.
Unmanned locomotives can be guided in the industry along a desired route as long as the distance travelled by the vehicle and its driving direction can be determined. The vehicle direction can be found out with sufficient accuracy by means of a gyroscope. Conventionally, many different types of systems have been used to control or regulate the operation of trains. A typical system is to use wayside markers to indicate the condition of the track and the maximum speed allowable over that portion of the track. However, a wayside marker systems may be obeyed by the engineer of the train, or totally ignored depending on the engineer. While all industries emphasize safety first, they also emphasize the train schedule which may be difficult if optimum speed is not maintained.
While exceeding the speed given in the locomotive order is in violation of the safety regulations due to which the roadbed is being seriously damaged with each speeding locomotive that travels thereon. As the train exceeds the speed limit, the force of the wheels against the rails tends to loosen or bend the rails (in case of rail based industrial locomotives) thereby resulting in train derailments with the attendant damage to property and possible loss of material and productivity. Excessive speeds of trains are probably the leading cause of damage to the roadbeds, and consequently the leading cause of various problems during operation. The speed may be controlled by a remote controller offboard of the locomotives. However, over a period of time the remote controller does not show or depict the accurate speed of the locomotive which may provide wrong information to the train engineer or operator. Thus, leading to either increasing speed over the threshold limits or running the locomotive at lower speeds.
Numerous methods have been used in the past in an attempt to regulate or control the speed of trains without taking away the function of the train engineer or operator. However, in the conventional methods of regulating speed of locomotive, it is difficult for the train engineer/locomotive pilot determine the speed of the locomotive from a remote location in case of false information depicted by the remote controller. Due to the difficulty in determining speed by the train engineer, the chances of over speeding of the locomotive are prominent. Over speeding of the locomotive may cause unanticipated damages to the locomotive which halts the process related to it for a substantially longer period of time.
The problems discussed hereinabove are just some of the numerous problems with controlling and ensuring the proper operation of the train within the speed limits thereby ensuring the maximum safety as is emphasized by the industry. It becomes essential to have some type of system and method in place that ensures that the train is operating within the predetermined speed limits thereby decreasing the possibility of derailment and/or damage to the tracks.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional arts.

Embodiments of the present disclosure discloses a system for evaluating accuracy of a remote operating module of a locomotive in an industrial zone. The system may aid in calibrating the remote operating module i.e., remote control module used to remotely operate a locomotive within the industrial zone. The system of the present disclosure includes a control module and at least one speed sensor which may be communicatively coupled to the control module. The at least one speed sensor may be associated with a wheel of the locomotive. The at least one speed sensor may be configured to transmit a first speed signal of a wheel to the control module. The control module based on the first speed signal may determine a first speed of the wheel. In an embodiment, the at least one speed sensor is at least one of hall effect sensor, variable reluctance sensor and RF sensor. The at least one speed sensor is accommodated in a carrier defined proximal to the wheel and the at least one speed sensor faces a plurality of indicia such as extensions defined on the wheel.

Hereinafter, preferred embodiments of the present disclosure will be described referring to the accompanying drawings. While some specific terms directed to a specific direction will be used, the purpose of usage of these terms or words is merely to facilitate understanding of the present invention referring to the drawings. Accordingly, it should be noted that the meanings of these terms or words should not improperly limit the technical scope of the present invention.
Generally, a locomotive may be used in industrial applications to haul materials such as but not limiting to molten metal, raw materials, ore materials, and the like, from one part of the industry to another part of the industry. In some embodiments, the locomotive may also find its application in hauling materials within various sites. Also, the said locomotives in addition to hauling materials may also be structured to load materials. The locomotive may include a chassis supported on a plurality of wheels (2) of which at least one may be a drive wheel driven by an engine through power transmission. The engine may be an electric motor, a combustion engine, a hydraulic motor or any such devices for providing torque. In an embodiment, the power transmission may typically include a gear system, differential gear and other power transmission members that may be designed to transmit the torque from the engine to the drive wheels. The locomotives that are used in the industrial zones are typically unmanned and may be controlled from a remote location off-board of the locomotive. Such locomotives may be equipped with a control unit, which may be arranged to control the actuators provided in the locomotive for steering and operating.
Furthermore, the locomotive may include data transmission modules by means of which the control unit may be configured to establish a data transmission connection to a remote operating module (M) off-board of the locomotive. The remote operating module (M) may be handled by an operator also referred to as train engineer or it may be located in an enclosed space such as control room. In an embodiment, the control unit, and the remote operating module (M) may be a computer or similar device. The remote operating module (M) in addition to controlling the steering, coupling, decoupling and similar operations may be configured to control speed of the locomotive. The remote operating module (M) may be configured to send acceleration and deceleration speed signals to the control unit on-board of the locomotive to increase or decrease the locomotive speed. An indication unit (I) may be associated with the remote operating module (M) to indicate speed of the locomotive. Although, the remote operating module (M) may be used to control speed of the locomotive, over a period of time the remote operating module (M) requires calibration. Such remote operating modules (M) fail to evaluate and indicate the accurate speed levels of the locomotive due to various data transmission issues and other such factors.
Referring now to drawings, a system for evaluating accuracy of a remote operating module (M) of a locomotive in the industrial zone incorporating the principles of the present disclosure is illustrated in FIG.1. The system may be depicted by referral numeral (10) in the FIG.1. The system (10) of the present disclosure may be directed to determine the accuracy of the remote operating module (M) that may be used to control the speed and various such parameter of the locomotive. In an embodiment, the system (10) may be a simulator to determine accuracy of the remote operating module (M). The term simulator refers to a machine designed to provide a realistic imitation of the controls and operation of a vehicle or other complex system. Since the locomotives in the industrial zones are used to haul various materials, determining accuracy of the remote operating module (M) on the real-life locomotive would not be a feasible task. Hence, the system (10) of the present disclosure may be used with a replica of a wheel (2) of the locomotive to determine accuracy of the remote operating module (M). However, the system (10) may be employed on the working model of the locomotive.
As shown in FIG.1, the system (10) may include a skeletal structure or a frame defining a shaft or a hub (H) to accommodate the wheel (2) of the locomotive. In some embodiments, the wheel (2) mounted on the hub (H) may be a replica of the wheel of the locomotive and may be made of materials similar to that of the actual wheel of the locomotive. In an embodiment, the replica of the wheel (2) may also be made of any such materials which may serve the purpose including polymeric material, and composite materials. Further, the skeletal structure may be defined with a carrier (F) proximal to the hub (H). The carrier (F) may be a flange kind of structure defined with a slot. In an embodiment, the slot may be configured to accommodate at least one speed sensor (1). The at least one speed sensor (1) may be at least one of but not limiting to a hall effect sensor, variable reluctance sensor and a RF sensor. The carrier (F) ensures that the at least one sensor (1) is positioned proximal to the wheel (2). In an embodiment, a sensing module of the at least one sensor (1) may be positioned in a way it faces a plurality of indicia (E) defined on the wheel (2). The plurality of indicia (E) may be arranged along a circumference on side face of the wheel (2). That is the plurality of indicia (E) may be arranged radially around the hub of the wheel (2). In an embodiment, the plurality of indicia (E) may be extensions defined on the wheel (2). The extension (E) may be a plurality of bolts joined on along the circumference of the wheel (2) but not limiting to the same.
The at least one sensor (1) may be communicatively coupled to a control module (S) associated with the system (10). The control module (S) may be configured to determine speed of the wheel (2). In an embodiment, the remote operating module (M) may be operatively connected or interfaced with the wheel (2). The remote operating module (M) may be configured to determine speed of the wheel (2). As described hereinabove, the remote operating module (M) may be configured to perform various functions including determining speed, steering and the like of the locomotive. The method of determining the accuracy of the remote operating module (M) may be elucidated hereinafter with the aid of FIG.2.
FIG.2 is an exemplary embodiment of the present disclosure, illustrating a flowchart of a method for remote speed evaluation of the locomotive in the industrial zone.
As illustrated in FIG.2, the method comprises one or more blocks illustrating the method for remote speed remote speed evaluation of a locomotive in the industrial zone. The method may be described in the general context of computer-executable instructions. Generally, computer- executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform functions or implement abstract data types.
The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
Now referring to FIG.2 in conjunction with FIG.1, the at least one speed sensor (1) associated with the wheel (2) and communicatively coupled to the control module (S) may be configured to detect a first speed signal [as shown at block 200]. In an embodiment, the first speed signal may be indicative of speed of the wheel (2). The wheel (2) may be rotated by at least one of automatic means and manual means. The automatic means include actuators to initiate rotational motion of the wheel (2), or the wheel (2) may include a handle [not shown] to be rotated by the operator. The at least one speed sensor (1) may be configured to sense the speed between each of the plurality of indicia (E). Upon sensing the speed between each of the plurality of indicia (E), the at least one speed sensor (1) may generate a pulse wave indicating the first speed signal. In an embodiment and as shown at block 201, the control module (S) may be configured to receive and read the pulse wave generated by the at least one sensor (1). The control module (S) based on the received pulse wave determines a first speed of the wheel (2). The control module (S) may indicate the speed of the wheel (2).
At block 202, the remote operating module (M) may be interfaced with the wheel (2) and may be configured to determine second speed of the wheel (2). In an embodiment, the remote operating module (M) may detect the second speed simultaneously with the first speed which is being detected by the at least one speed sensor (1). As shown at block 203, the first speed and the second speed may be compared. The first speed and the second speed may be compared by a manual methods or automated methods. The second speed may be compared with first speed and the difference if any may be stored. Based on the comparison the accuracy of speed detection of the remote operating module (M) may be determined. If the first speed and the second speed is similar, the remote operating module (M) may be adjudged accurate. In case, the first speed and the second speed is not similar, the remote operating module (M) may be determined inaccurate. Based on the comparison the remote operating module (M) may be calibrated to read similar values to that of the first speed signal.
The system may aid in calibrating the remote operating module (M) used to remotely operate a locomotive within the industrial zone.
In an embodiment of the disclosure, the control module (S)/remote operating module (M) may be a centralized control unit, or a dedicated control unit associated with the system (10). The control module (S)/remote operating module (M) may be implemented by any computing systems that is utilized to implement the features of the present disclosure. The control unit may be comprised of a processing unit. The processing unit may comprise at least one data processor for executing program components for executing user- or system-generated requests. The processing unit may be a specialized processing unit such as integrated system (bus) controllers, memory management control units, floating point units, graphics processing units, digital signal processing units, etc. The processing unit may include a microprocessor, such as AMD Athlon, Duron or Opteron, ARM’s application, embedded or secure processors, IBM PowerPC, Intel’s Core, Itanium, Xeon, Celeron or other line of processors, etc. The processing unit may be implemented using a mainframe, distributed processor, multi-core, parallel, grid, or other architectures. Some embodiments may utilize embedded technologies like application-specific integrated circuits (ASICs), digital signal processors (DSPs), Field Programmable Gate Arrays (FPGAs), etc.
In some embodiments, the processing unit may be disposed in communication with one or more memory devices (e.g., RAM, ROM etc.) via a storage interface. The storage interface may connect to memory devices including, without limitation, memory drives, removable disc drives, etc., employing connection protocols such as serial advanced technology attachment (SATA), integrated drive electronics (IDE), IEEE-1394, universal serial bus (USB), fiber channel, small computing system interface (SCSI), etc. The memory drives may further include a drum, magnetic disc drive, magneto-optical drive, optical drive, redundant array of independent discs (RAID), solid-state memory devices, solid-state drives, etc.
It is to be understood that a person of ordinary skill in the art may develop a system of similar configuration without deviating from the scope of the present disclosure. Such modifications and variations may be made without departing from the scope of the present disclosure. Therefore, it is intended that the present disclosure covers such modifications and variations provided they come within the ambit of the appended claims and their equivalents.
Equivalents
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding the description may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated in the description.
