[0002] The overhead contact line maintenance vehicle is a core piece of equipment for the maintenance and emergency repair of rail transit power supply systems. The DPT-type overhead contact line maintenance vehicle, due to its high efficiency and flexibility, is widely used in overhead contact line maintenance operations on high-speed and conventional railway lines. Because the operating environment of the overhead contact line maintenance vehicle is complex, involving the coordinated operation of multiple systems such as track, train control, and GYK (Gas Yard Control), it places extremely high demands on the professional skills and emergency response capabilities of the operators. Current training for DPT-type overhead contact line maintenance vehicles mainly relies on hands-on training on actual vehicles, which has the following drawbacks: 1) Hands-on training is costly, including vehicle depreciation, fuel consumption, and track occupancy fees; 2) The training process carries safety risks, especially during training on abnormal operating conditions and emergency response, which can easily lead to equipment damage or personnel injuries; 3) Hands-on training cannot simulate extreme scenarios such as complex weather, equipment failures, and emergencies, limiting the training coverage; 4) The evaluation of training effectiveness relies on instructors' manual observation, which is highly subjective, has inconsistent evaluation standards, and cannot fully record the entire operation process, making it difficult to accurately trace errors.

[0003] Existing simulation training systems often suffer from fragmented functionality and low fidelity: some systems focus only on scene simulation, lacking complete ground train control system support; some systems do not integrate GYK simulation and fault simulation functions, failing to achieve full-process practical training; and most systems lack automated and standardized evaluation modules, making it difficult to meet the needs of large-scale and precise training.

[0020] Figure 1 This is a schematic diagram of the framework of a DPT-type overhead contact line operation vehicle simulation training and evaluation system. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1 The present invention provides a DPT-type overhead contact line operation vehicle simulation training and evaluation system, including a line visual module, a sound simulation module, a ground train control simulation module, a driver's cab simulation module, a controller interface module, a GYK simulation operation and testing module, a communication server module, and an instructor monitoring and management module.

[0023] I. System Overall Structure In this embodiment, the communication server module serves as the core of the system's data interaction and scheduling. It is connected to the line visual module, sound simulation module, ground train control simulation module, driver's cab simulation module, controller interface module, GYK simulation operation and testing module, and instructor monitoring and management module. This allows for data interaction, status verification, data processing, and real-time monitoring between the modules, ensuring that all functional modules of the system operate collaboratively under a unified spatiotemporal logic and operating rules.

[0024] The controller interface module is used to receive operation commands input by trainees through operating devices during practical training, and transmit the operation commands to the corresponding functional modules. At the same time, it transmits the operating status and feedback information of each functional module back to the trainee's operating terminal in real time, so as to form a closed-loop response of operation and feedback, ensuring the real-time performance and consistency of the simulation training process.

[0025] The instructor monitoring and management module is used for overall system configuration, fault and emergency event settings, training process monitoring, personnel information management, and assessment. The line visual module, sound simulation module, ground train control simulation module, driver's cab simulation module, and GYK simulation operation and testing module work together under the coordination of the communication server module to construct a full-scene simulation driving environment for the DPT type catenary operation vehicle.

[0028] The line view module performs real-time data matching with the GYK simulation operation and testing module. It can automatically match the line view of the corresponding kilometer marker according to the selected training section and training starting point, and supports the adjustment of running speed. When the side track number is entered in the GYK system, the line view module automatically switches to the line video of the corresponding track to achieve a line display effect consistent with the actual working environment.

[0034] TSRS is used to receive temporary speed limit instructions issued by the dispatcher and distribute the temporary speed limit information to the train control center and the radio block center to adapt to the operational requirements of CTCS-2 or CTCS-3 train control systems.

[0035] The TCC includes a safety host subsystem, a drive and acquisition subsystem, a communication interface subsystem, a maintenance subsystem, and a power supply subsystem. It is used to control the track circuit coding and active transponder information based on the train's position, interlocking route status, and temporary speed limit information, thereby providing the train with operating permission.

It supports turnout switching control, red light strip simulation, signal opening, and train addition operations. It also supports infinitely zoomable interface and full-screen display of a single station or the entire line.

[0037] V. Driver's console simulation module The driver's cab simulation module simulates the indicator lights, buttons, switches, and dial functions of the DPT type overhead contact line operation vehicle driver's cab in pure software form. It is used to collect the trainee's operation commands and provide the corresponding status information to the trainee, enabling the trainee to complete the complete driving operation training without relying on the real vehicle.

[0038] VI. GYK Simulation and Testing Module The GYK simulation operation and testing module is used to simulate the speed, wind pressure, locomotive signals, operating condition control and display of the GYK system, and to collect GYK braking signals. It also supports the setting of speed, pipe pressure and track signal parameters.

[0039] Meanwhile, the GYK simulation operation and testing module also has functions such as ground data verification and graphical display, disclosure and review, equipment inspection and maintenance, and voice dumping and playback, so as to meet the training needs of GYK system operation and interpretation capabilities during training and assessment.

[0040] VII.

The fault and accident simulation submodule is used to realize weather and time simulation, emergency event simulation, and emergency event and fault management. The weather and time simulation supports the simulation of changes in rain, snow, fog, light and visibility. The emergency event simulation supports preset or real-time setting of emergency events, and the visual system responds instantly. The emergency event and fault management supports the addition, modification and deletion of events, and supports offline setting during the course development stage or real-time activation and cancellation during practical training, thereby realizing full-process management of faults and emergencies. The instructor management submodule is used for daily system maintenance, course and assessment content development, monitoring of practical training and assessment processes, and student guidance. The personnel information management submodule is used to manage the employee ID, name, station / section, workshop, position, and contact information of flight attendants and system users, and to assign permissions.
