Description

Technical Field

[0001] The present invention relates to the technical field of train training, and in particular to a rail train traction training system. Background Art

[0002] With the rapid development of the rail transit industry, the demand for skilled rail vehicle operators is growing. The traction system is a core, critical system of rail vehicles, directly determining their operational safety. It is a required course for students at relevant universities and newly hired professionals at vehicle-using companies. Because this program requires students to develop practical operational skills and hands-on skills, students require the use of teaching instruments for hands-on training. Currently, there are two main types of traction training devices. One utilizes the traction system of a real train for teaching and training. This allows students to get up close and personal with the actual traction system. However, due to the high voltage and current requirements of the traction system, students are generally limited to observation and learning, unable to operate independently. The other is a simplified training device that reduces the voltage and current of the actual traction system and uses simple electrical components instead of key equipment. While students can operate independently, the structure and principles of the training device are overly simplistic and limited, preventing them from gaining a comprehensive understanding of the traction system and the working principles of vehicle operation. Summary of the Invention

[0035] The assessment and scoring interface predefines a set of standardized operating steps. During the assessment process, the student's operating steps are monitored in real time. After the student completes the operation, the standardized operating steps are compared and the student's score, time taken and reason for the error are given; and

[0036] The AI-assisted learning interface guides students to relearn weak areas based on their assessment results;

[0037] The hardware unit includes:

[0038] a control module, communicatively connected to the software unit; and

[0039] The drive motor and the load motor are connected to the traction transmission, the drive motor is electrically connected to the control module through the power regulation module, and the load motor is electrically connected to the control module through the load control module. The drive motor simulates the traction motor of a real vehicle, and the load motor simulates the running resistance of a real vehicle;

[0040] The voltage and current of the hardware unit are proportionally reduced according to the rated values ​​of the real vehicle, but are restored to the operating voltage and current of the real vehicle in the software unit for display;

[0041] The control module is a PLC controller, and the power regulation module is a frequency converter; or the control module is a single chip microcomputer, and the power regulation module is a drive module using power electronic power devices.

[0042] In this embodiment, the software unit of this application is implemented using a development tool, and a parameter setting interface, an operation display interface, a circuit logic diagram display interface, and a real-time data display interface are built in the scene. Communication between the software unit and the hardware unit is achieved through a communication protocol, and operation information is sent to the control module in real time to achieve control of the actual hardware circuit.

[0043] The hardware unit includes a control module, drive motor, and load motor. It eliminates the need for actual high-voltage equipment or high-power motors, instead replicating the core control logic of the traction system through software algorithms. There are two implementation options for the control module: one using a PLC controller as the core controller, and the other using a single-chip microcomputer as the core controller.

[0044] (1) PLC controller is used as the core controller;

[0045] A PLC controller controls a frequency converter to simulate the traction converter of a real vehicle. The PLC controller controls the frequency converter's output frequency to adjust the drive motor's speed, simulating the operating conditions of a real vehicle's traction motor. A control program is written in the PLC controller and established communication with the software unit. When operating within the software interface, operational information is transmitted through the PLC controller and the frequency converter to control the traction motor, simulating different vehicle operating conditions. Using the frequency converter's real-time feedback circuit and the drive motor's operating data, standardized scaling instructions are written into the program, feeding the frequency converter's feedback values ​​to the PLC for processing. This feedback data is displayed according to real vehicle data, displaying not only current and voltage curves but also animated displays of the actual vehicle's traction motor speed.

[0046] (2) Using a single-chip microcomputer as the core controller;

[0047] A single-chip microcomputer (MCU) is used as the control and drive module to simulate the traction converter of a real vehicle. Control logic is written into the MCU and established communication with the software unit. When operating in the software interface, the operational information is transmitted through the MCU and the drive module via PWM signals to control the speed of the drive motor, simulating the different operating conditions of the traction motor of a real vehicle. Sensors are also used to detect the operating parameters of the drive motor and circuit. After geometric amplification, these parameters are fed back to the real-time data display interface of the software unit in real time, displaying not only the current and voltage curves but also the speed of the real vehicle's traction motor through animation.

[0048] The software unit communicates with the hardware unit, sending its operational instructions to the hardware unit via a communication protocol. The control module controls the operation of the drive motor to simulate the operating conditions of a real vehicle's traction system. The hardware unit uses two motors to simulate the vehicle's actual driving conditions. One drive motor simulates the traction motor on a real train, and the other load motor simulates the vehicle's resistance under different operating conditions. The voltage and current of all hardware circuits are scaled down proportionally to the rated values ​​of the real vehicle, but restored to the actual vehicle's operating voltage and current on the software display interface. The restored rotation of the traction motor and the working animation of the traction converter are displayed. The operation of the hardware unit is completely controlled by the operation buttons on the software interface, realistically restoring the workflow and principles of the vehicle's traction system.

[0049] The training system of the present invention adds a traction characteristic curve design interface, so that students can understand the source of the design requirements of the traction system. The train driver's operation and the traction system control operation are restored with high fidelity. Through the communication between software and hardware, the instructions of the software operation interface are conveyed to the hardware circuit, and the hardware operation data are fed back in real time on the software interface. By dynamically displaying the traction circuit schematic, students can understand the power transmission path when the traction system is working, and can more intuitively see the power transmission and recovery process when the students are driving. By using two motors to pull together, the working state of the real vehicle traction motor under different working conditions can be simulated, and the operation status of the train can be reflected in real time, making the teaching more realistic. By analyzing the learning and assessment scoring data of each student and using artificial intelligence analysis methods, reasonable personalized learning suggestions are given to different students to achieve teaching according to their aptitude. It is suitable for skill training of students in relevant majors in colleges and universities and vehicle users, which greatly improves the training efficiency.
