[0002] The railcar control system (GYK) is a crucial component for the safe operation of rail vehicles. Its stability and reliability directly impact the safety of rail vehicles, making the maintenance and repair of GYK equipment extremely important. GYK equipment maintenance and repair is a highly specialized and technically demanding task. To improve the technical skills and emergency response capabilities of maintenance personnel, appropriate training is necessary.

[0003] The utility model patent with prior art publication number CN219777831U discloses a simulation system for simulating GYK operation, including a GYK host, a first DC regulated power supply, a braking isolation device box, a control component, a first DMI, a second DMI, a first locomotive signal, a second locomotive signal, a first speaker, a second speaker, a first prompt button group, a second prompt button group, a sensor component, an output component, and a working condition simulation component. Utility Model Content

[0004] Currently, maintenance training for GYK equipment largely relies on traditional classroom teaching and on-site practice. Classroom teaching often emphasizes theoretical knowledge and lacks practical training, resulting in trainees lacking practical experience in actual operation. On-site practice is limited by the number of actual equipment and site conditions, which cannot meet the needs of large-scale training. Furthermore, due to the complexity of GYK equipment, various unexpected situations may occur during actual operation, posing safety hazards when practicing on real equipment.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a GYK maintenance and inspection teaching and training integrated device, including an operating console and a cabinet. A locomotive signal is provided at each of the two ends of the top of the operating console; a computer is provided in the middle of the top of the operating console; an on-board computer and two sets of human-machine interaction systems are embedded in the operating console; large and small gates and a driver controller are provided on the surface of the operating console; a power supply box is provided at the top of the cabinet; a GMS device is provided in the middle of the cabinet; a GYK host is provided below the GMS device; a fault simulation box and a signal simulation box are provided below the GYK host; and a terminal block is provided on the back of the cabinet.

[0006] Specifically, the human-machine interaction system embedded in the control panel includes a DMI (Digital Machine Interface), an MMI (Multi-Machine Interface), and a transmitter / receiver; a speaker is installed at each end of the top of the control panel, below the locomotive signal.

[0007] Specifically, the signal analog plug-in box is connected to the GYK host via a cable, the GYK host is connected to the DMI and the locomotive signal via a cable, and the DMI is connected to the speaker via a cable.

[0008] Specifically, the connecting cables between the various devices are connected to the output end after exiting from the input end, passing through the terminal block and the fault simulation box; the terminal block is connected in series in the middle of the cables of each device, and the terminal block and the fault simulation box are connected in parallel.

[0009] Specifically, the signal simulation box provides various vehicle signals to the GYK host, simulating pipe pressure, speed, and operating conditions, and displays the corresponding pipe pressure values, speed values, and operating condition information on the DMI. At the same time, it receives braking information fed back by the GYK host. The signal simulation box has a built-in communication switch. In manual mode, various analog signals can be set to output through the buttons on the signal simulation box. In automatic mode, analog output commands can be set through a computer.

[0010] Specifically, the fault simulation box contains several fault simulation components. These components control the high and low level signals of the microcontroller's I / O port to drive relay coils to close and open, control the continuity of signal cables between devices, and detect the status of the relays. Each fault simulation component has multiple relays that can control multiple signals. The fault simulation components use a CAN module to communicate with the computer, which controls the relays and detects their status. The fault simulation component interfaces are configured with different pin states. The microcontroller identifies different pins through an optocoupler module to obtain different addresses and distinguish each component.

[0011] Specifically, the two ends of the terminal block are connected to the signal input and output respectively. When a fault is set, the user can measure and check the signal connection status through the terminal block; or short-circuit the terminal block with a special tool to force the relay to close and restore the faulty signal.

[0012] Specifically, the vehicle computer is connected to the computer via a 232 serial port, the signal simulation box is connected to the GYK computer via a 232 serial port, the fault simulation box is connected to the computer via CAN communication, and the GMS device is connected to the computer via a 422 serial port.

[0013] Specifically, the power supply box has a built-in switching power supply module. After 220V is input to the power supply box, it is converted into multiple 24V outputs by the switching power supply to power other devices.

[0014] Specifically, the brakes and driver's controller are mechanical structures composed of a handle and a potentiometer. When the handle is rotated, it drives the potentiometer to rotate through gears, supplying power to the brakes and driver's controller. When the resistance of the potentiometer changes, it can output a continuously changing voltage value. The vehicle's computer collects the continuously changing voltage values ​​of the brakes and driver's controller through its built-in microcontroller I / O and sends them to the computer for data processing. The computer converts the voltage values ​​into corresponding pressure values, speed values, operating conditions, and time information, which are then sent to the vehicle's computer and displayed on the screen.

[0015] The beneficial effects of this utility model are as follows: Through integrated design, it realizes functions such as fault simulation, parameter setting, and data acquisition for GYK equipment. Employing a combination of simulated operation drills and teaching simulation training, it provides training and assessment for maintenance personnel in the electrical section on the working mechanisms of track vehicle operation control equipment and related electrical equipment, equipment fault repair, and standardized operations. By controlling the disconnection of different cable connection points, it can specifically simulate common fault phenomena and provide an intuitive operating interface and real-time feedback. This not only effectively improves teaching and training results but also helps enhance the professional skills and adaptability of maintenance personnel. Attached Figure Description
