Description

POSITIVE TRAIN CONTROL SIMULATION SYSTEM

WITH EMERGENCY AND HORN APPLICATIONS AND METHOD THEREFOR

TECHNICAL FIELD

[0001] The present disclosure relates generally to a simulation of locomotive emergency and horn enforcement events, and more specifically to systems and methods for simulating physical and electrical characteristics corresponding to Positive Train Control emergency and horn enforcement events.

BACKGROUND

[0002] Positive Train Control (PTC) systems use communication-based and processorbased train control technology to reliably and functionally prevent train -to-train collisions, overspeed derailments, incursions into established work zones, and movements of trains through switches left in the wrong position. PTC systems harmonize interoperability between electrical and mechanical systems to act in moments when a locomotive disregards a safety plan. For example, the PTC system operates in response to identifying speed of the locomotive is greater than the route speed allows enabling a penalty to the locomotive by applying the brakes. The

Federal Railroad Administration mandates PTC systems operating on every mile of railroad meaning every locomotive on the railroad includes a PTC system. [0003] Teaching how a PTC system operates on a locomotive currently lacks any ability to simulate the system components. While training on a locomotive with the PTC system is ideal, this is unlikely because of the inability for a trainer to obtain the locomotive for the time to properly train the upcoming engineers and conductors. Training engineers and conductors can take weeks, months, even years, so removing a locomotive from use can create dissatisfactory efficiency. Additionally, because trainees focusing on becoming an engineer or a conductor cannot practice in a practical environment, the trainees receive insufficient training. Engineers and conductors without proper training with the PTC system can frequently trigger the PTC system on the locomotive by traveling with unsafe locomotive handling. While the PTC system ensures for enhanced safety the risk continues for train derailments and train-to-train collisions.

SUMMARY

[0004] The present disclosure achieves technical advantages as a system and method for simulating PTC systems in a local environment using software and hardware, removing the training program from using an actual locomotive. The system can simulate various functionalities of the PTC system in a classroom environment using software and hardware components. For example, the system can couple the software of a train management computer (TMC) to electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). For example, the TMC enables the hardware and software of the system to communicate information relevant to analyzing warnings from the PTC system. The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing trainees to experience the PTC system for optimum training.

[0005] The present disclosure solves the technological problems of providing insufficient training for interacting with the PTC system and restricting trainees from experiencing the PTC system in action by simulating warnings and actions from the PTC system using stand-alone system components, which removes the locomotive from at least some of the training program. By removing the locomotive from at least some of the training program yields flexibility to the instructors while optimizing education for the trainees. Additionally, removing the locomotive from some of the training saves time for the training program while enabling immediate feedback to handling the locomotive in response to the PTC system warnings. Separating at least the initial PTC training for the novice engineers and conductors from operating on locomotives also minimizes liability and risk, such as breaking components on the locomotive and potentially causing a hazardous safety environment.

[0006] [0006] The present disclosure provides a technical solution to the technical problem by providing software and hardware components for instructional purposes. Particularly, the present disclosure focuses on optimizing training conditions for interacting with the PTC system. In a real-world environment, the PTC system can transmit warnings and instructions to the locomotive instructing it how to respond to certain situations. The present disclosure provides control mechanisms interacting between software and hardware components to simulate a locomotive environment. The simulated locomotive environment enables a user to practice interacting with the PTC system without physical repercussions, such as the PTC system applying the brakes to the locomotive. The present disclosure enables users to interact with locomotive components in a system coupling components corresponding to the PTC system in a classroom environment.

[0041] At step 1016, in one embodiment, the control logic 1000 can convert the first pressure to the second pressure. For example, convert the first pressure to the second pressure to simulate a train penalty condition. In an example, the control logic 1000 can control the air pneumatic components to reduce the first pressure to the second pressure at the service rate. For example, the service rate can correspond with a pressure change rate from the first pressure to the second pressure based on various mechanical factors.

The emergency application control logic 1100 can be implemented as an algorithm on the TMC, a machine learning module, a client, a database, or other suitable system. Additionally, the emergency application control logic 1100 can implement or incorporate one or more features of the PTC simulation system 200, including the display management system 202, communication system 204, locomotive control stand system 206, and simulation system 208. The emergency application control logic 1100 can be achieved with software, hardware, firmware, assembly language, machine instructions, an API, a network connection, a network transfer protocol, HTML, DHTML, JavaScript, Dojo, Ruby, Rails, other suitable applications, or a suitable combination thereof.

[0045] The emergency application control logic 1100 can leverage the ability of a computer platform to spawn multiple processes and threads by processing data simultaneously. The speed and efficiency of the emergency application control logic 1100 can be greatly improved by instantiating more than one process. However, one skilled in the art of programming will appreciate that use of a single processing thread may also be utilized and is within the scope of the present disclosure.

[0046] In one embodiment, commands or data can be received via user input generated on a display or client, such as a screen tap, swipe, mouse click, key press, voice command, or other suitable mechanism. In another embodiment, the inspection commands or data can include inspection data having one or more fields, parameters, characteristics, or metadata, related to an inspection. The emergency application control logic 1100 then proceeds to step 1102.

[0047] At step 1102, in one embodiment, the control logic 1100 can receive at least one input. For example, the at least one input can correspond to a train penalty condition. In another example, the train penalty condition can correspond to a PTC application for simulation purposes. The control logic 1100 proceeds to step 1104.

In an example, the control logic 1100 can receive the at least one input from a computer, such as the TMC 104. The control logic 1100 proceeds with step 1106. [0049] At step 1106, in one embodiment, the control logic 1100 can determine whether the at least one input is a penalty warning. For example, the penalty warning corresponds with the PTC simulation application. If the at least one input is the penalty warning, the control logic 1100 proceeds to step 1108. If the at least one input is not the penalty warning, the control logic 1100 proceeds to exit the process.

[0050] At step 1108, in one embodiment, the control logic 1100 can receive an instruction corresponding to the penalty warning. For example, the instruction can include information about the control logic 1100 taking an action corresponding to the PTC simulation application. In an example, the instruction can include the action corresponding to the penalty warning. For example, the instruction can instruct an air pneumatic system to activate. The control logic 1100 proceeds with step 1110.

[0051] At step 1110, in one embodiment, the control logic 1100 can determine whether a first cutout switch is closed. For example, the first cutout switch can indicate whether a circuit driving the penalty application is active. In an example, the first cutout switch can be closed when no errors exist corresponding to the PTC simulation. If the first cutout switch is closed, the control logic 1100 proceeds with step 1112. If the first cutout switch is open, the control logic 1100 proceeds to terminate the process.

For example, the air pneumatic components can include a pulse conversion relay, a penalty magnetic valve, an interval delay relay, and a vent magnetic valve. In another example, the control logic 1100 generate electrical signals to energize the air pneumatic components. The control logic 1100 then proceeds to step 1114. [0053] At step 1114, in one embodiment, the control logic 1100 can supply compressed air to the air pneumatic components at a first pressure. For example, the control logic 1100 can supply the compressed air to the air pneumatic components at the first pressure for a penalty period.

In another example, the second voltage can be 74 volts. The control logic 1100 the proceeds to step 1124.

[0058] At step 1124, in one embodiment, the control logic 1100 can convert the first pressure to the second pressure. For example, convert the first pressure to the second pressure to simulate a train penalty condition. In an example, the control logic 1100 can control the air pneumatic components to reduce the first pressure to the second pressure at the service rate. For example, the service rate can correspond with a pressure change rate from the first pressure to the second pressure based on various mechanical factors. The control logic 1100 proceeds to step 1126.

[0059] At step 1126, in one embodiment, the control logic 1100 can determine whether a second cutout switch is closed. For example, the second cutout switch can indicate whether a circuit driving the penalty application is active. In an example, the second cutout switch can be closed when no errors exist corresponding to the PTC simulation. If the second cutout switch is closed, the control logic 1100 proceeds with step 1128. If the second cutout switch is open, the control logic 1100 proceeds to terminate the process.

[0062] At step 1132, in one embodiment, the control logic 1100 can reduce the second pressure. For example, the control logic 1100 can reduce the second pressure to 0 psi. In another example, when the control logic 1100 vents the compressed air, a brake system of a locomotive or simulated locomotive engages applying the emergency application.

Tn an example, the electrical components can include conductive wire to transfer electrical signals (e.g., the electrical signals indicating a transfer of information and/or power). In another example, the air compressor 512, the penalty magnetic valve 516, the vent magnetic valve 518, and the penalty assembly 318 can interconnect with mechanical components to transfer compressed air (i.e., designated in FIG. 4 with dash dot lines). In an example, the mechanical components can include rigid or flexible hose, made of various types of material.

For example, the first cutout switch board 402 can include one of various materials commonly used as the insulating slab. In an example, the insulating slab can include materials such as polyester, teflon, silicon wafer, among other insulating materials. In another example, the electronic terminals can include inputs or outputs from various electronic components used in the simulation assembly 300. In an example, the inputs and outputs can include copper terminals from switches, relays, or some other electronic component. In another example, the first cutout switch board 402 can provide an interface between the TMC 104 and the cutout switches 1204.
