The railcar's operational data is of paramount importance, and comprehensive testing and verification of this data are essential to guarantee the reliability and safety of vehicle operation.

[0003] Currently, GYK data testing mainly relies on manual verification and field experiments. Manual verification is inefficient, time-consuming, prone to human error, and unable to simulate dynamic changes. Field experiments are costly, requiring actual track resources, increasing testing costs, and are limited by weather and time constraints. Existing technology CN220076381U, an automatic verification device for GYK reveal data, includes a PC and an automatic verification tester for GYK reveal data.

This device achieves automatic simulation verification during the verification of GYK reveal data, improving verification and review efficiency and avoiding the risk of incomplete simulation verification. However, it can only perform simulation testing on one set of data at a time, resulting in low data verification efficiency. Summary of the Invention

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Example 1: This embodiment is a GYK device data simulation and verification device, the overall structure of which is as follows: Figure 1As shown, it includes: a display control unit 1, a speaker 2, a switch 3, a CAN communication module 4, a simulation host 5, a power supply box 6, a start switch 7, an air switch 8, and a DMI unit 9. The display control unit is connected to the simulation host, the power supply box is connected to both the simulation host and the display control unit, the CAN communication module is connected to both the simulation host and the display control unit, the switch is connected to both the simulation host and the display control unit, the start switch is connected to the power supply box, the air switch is connected to the power supply box, the DMI unit is connected to the simulation host, and the speaker is connected to both the display control unit and the DMI unit.

[0020] It should be noted that in this embodiment, the operating state of GYK during the simulated operation of the railcar is simulated by hardware circuits, not by computer software. The improvements are only made to the circuit structure and do not involve any improvements to the computer program.

[0021] This embodiment addresses the current practice of relying primarily on manual verification and field experiments for GYK data testing. However, manual verification is inefficient, time-consuming, prone to human error, and unable to simulate dynamic changes. Field experiments are costly, requiring actual track resources and increasing testing costs, and are also limited by weather and time constraints. Furthermore, existing testing methods struggle to cover all possible operating scenarios, potentially leading to undetected technical issues. This embodiment provides a GYK equipment data simulation and verification device for verifying GYK data, improving the reliability and efficiency of data modifications. The device simulates the differences between the modified old and new versions of data, sending different simulation commands to two simulation hosts. The corresponding DMI displays different operating states. The display control unit receives the GYK operating status information and captures the interface data to the display control unit, visually displaying the data differences. Comparing the simulation results of the new data with the expected results verifies the accuracy of the data modifications, effectively improving the verification efficiency and accuracy of data modifications, and reducing errors from manual testing.

[0022] Specifically, this embodiment provides a GYK equipment data simulation and verification device, which includes a display control unit, four speakers, a switch, a CAN communication module, two simulation hosts, a power supply box, a self-reset switch, an air switch, and two DMIs. These components are interconnected via cables to form a simulation system for GYK operation. This system can simulate the GYK's operating state during railcar operation. The two simulation hosts and two DMIs operate independently. The simulation hosts can simultaneously simulate and test two different versions of data (old and new) and display the different operating states on the DMIs. By comparing the simulated results of the new data with the expected results, the correctness of the data modification can be determined.

[0023] The simulation host includes a first simulation host and a second simulation host, both with identical structures, including an analog signal unit 21 and some GYK boards 20 used in actual railway bureau operations. The analog signal unit has circuits for detecting pipe pressure, speed, operating conditions, lamp type, and valve signals. The DMI unit includes a first DMI unit and a second DMI unit, each connected to one simulation host.

[0024] The analog signal unit includes a pipe pressure signal detection circuit 15, a speed signal detection circuit 16, a lamp type signal detection circuit 17, a valve signal detection circuit 18, and a working condition signal detection circuit 19. The pipe pressure signal detection circuit can detect 6 pressure signals. Upon receiving a pressure value, the analog-to-digital converter converts the received data into a corresponding voltage, which is then output through a voltage-to-current module. Each current output range is 4–20 mA. The speed signal detection circuit can simulate 8 speed square wave signals, with a phase difference of 90°±30° between each pair of speed signals. The working condition signal detection circuit can simulate 4 working condition level signals, with an output voltage of 20–30V. The lamp type signal detection circuit can simulate 8 lamp type signals, controlling the indicator lights to turn on or off or flash. Additionally, it has 4 valve signal detection circuits, capable of detecting the normal, emergency, pressure holding, and engine shutdown indicator valve signals for each GYK-160 series. The analog signal unit also has analog communication capabilities, capable of simulating voice recording and locomotive communication protocols, and forwarding data between the GYK-160 and the analog signal unit. After receiving the instruction from the analog signal, the analog signal unit forwards the data to the GYK-160. The GYK-160 executes the instruction of the corresponding analog signal and forwards the braking command back to the analog signal unit, thereby determining whether the analog state is correct.

[0025] The power supply box includes a power module 13, a power control board 12, and an emergency switch 14. The power control board employs a three-way optocoupler drive and relay control circuit. The first optocoupler drive and relay control circuit is connected to the display control unit and is used to control the power supply to the display control unit. The second optocoupler drive and relay control circuit is connected to the first emulation host and is used to control the power supply to the first emulation host, which is connected to the first DMI unit. The third optocoupler drive and relay control circuit is connected to the second emulation host and is used to control the power supply to the second emulation host, which is connected to the second DMI unit. The power supply box is connected to the start switch, the display control unit, and the emulation host via cables.

[0026] The operation of the GYK-160 railcar during operation is simulated using a simulation method. Two simulation hosts are run simultaneously for comparison, which can intuitively display the operation status under different data conditions, effectively improving the verification efficiency of data verification and the accuracy of data modification.

[0027] Example 2: This embodiment, based on Embodiment 1, adds an overall structural element to provide a GYK device data simulation and verification device, the overall structure of which is as follows: Figure 1 As shown, the device includes a main body 10 and casters 11 mounted below it. The main body is divided into two layers. The upper layer includes a display control unit, two DMI units, and four speakers. Two speakers are located below the display control unit, and the other two speakers are located below each of the DMI units. The lower layer includes a CAN communication module, a switch, a emulation host, a power switch, an air switch, and a power supply box. There are two emulation hosts, which are installed side by side in the middle of the lower layer. On the left side of one emulation host, the switch and the CAN communication module are arranged sequentially. On the right side of the other emulation host, the power supply box is installed. The air switch and the power switch are mounted on top of the power supply box.

[0028] The display control unit, speakers, switch, CAN communication module, air switch, and start switch are all existing components. The display control unit and two simulation hosts are connected to the switch. The analog signal units of the two simulation hosts receive information such as pipe pressure, speed, and operating conditions sent by the display control unit and perform corresponding signal processing. The GYK board simulates operation according to instructions and feeds back braking information to the analog signal units. The two can forward data to each other. The DMI unit is connected to the simulation host to receive and display the vehicle's operating status. The two simulation hosts are connected in parallel with the CAN communication module and connected to the display control unit to obtain the GYK's operating status information. The display control unit is also connected to the two DMI units via serial port and HDMI respectively to acquire the DMI unit's operating display interface and perform simulated button operations.

[0029] The GYK device data simulation and verification device provided in this embodiment is used to verify and test GYK-160 data, improving the reliability and efficiency of data modification. This device simulates the differences between the old and new versions of modified data, sending different simulation commands to two simulation hosts. The corresponding DMIs will display different operating states. The display control unit receives the operating status information of GYK-160 and captures the interface data to the display control unit, visually displaying the data differences. Comparing the simulation results of the new data with the expected results verifies the accuracy of the data modifications, effectively improving the verification efficiency and accuracy of data modification, and reducing errors caused by manual testing.

[0030] Example 3: Based on Embodiment 1 or Embodiment 2, this embodiment adds specific circuit structures for the power supply box and the simulation host, providing a GYK device data simulation verification device.

[0031] Specifically: like Figure 2 As shown, the power supply box includes an emergency switch, a power module, and a power control board. The input terminal of the power control board is connected to the power input interface, and the output terminal of the power control board is connected to the power module. The emergency switch is connected to both the power input terminal and the power module. In this embodiment, there are two control methods after one power input. One method implements a soft switching function through the power control board and the self-resetting switch, while the other method uses a self-locking switch to enable the device to operate even when the soft switching function fails.

[0032] The power control board includes a first optocoupler drive and relay control circuit, a second optocoupler drive and relay control circuit, and a third optocoupler drive and relay control circuit, which are used to control the power supply of the display control unit 1 and the two simulation hosts 5, respectively. The three optocoupler drive and relay control circuits have the same structure.

[0033] Taking the first optocoupler drive and relay control circuit as an example, the specific structure of this circuit is explained as follows: The first optocoupler drive and relay control circuit includes resistor R52, first optocoupler IC, resistor R53, resistor R54, transistor Q12, resistor R51, diode D12, light-emitting diode D11, and first relay. One end of resistor R52 is connected to the start switch, and the other end of resistor R52 is connected to the positive terminal of the light-emitting diode in the first optocoupler IC. The collector of the phototransistor in the first optocoupler IC is connected to one end of resistor R53 and one end of resistor R54. The other end of resistor R54 is grounded, and the other end of resistor R53 is connected to the base of transistor Q12. The emitter of transistor Q12 is grounded. The collector of transistor Q12 is connected to the anode of diode D12, one end of resistor R51, and the control signal input terminal of the first relay. The other end of resistor R51 is connected to the cathode of LED D11. The cathode of diode D12, the anode of LED D11, and port 30 of the first relay are all connected to a 12V power supply. Port 87 of the first relay is connected to the power module, and port 85 of the first relay is connected to the power input port. The first optocoupler drive and relay control circuit is used for power supply control of the display control unit.

[0034] The second optocoupler drive and relay control circuit has the same structure as the first optocoupler drive and relay control circuit, but it adds a resistor R56. One end of resistor R56 is connected to one end of resistor R52, and the other end of resistor R56 is connected to the positive terminal of the LED of the second optocoupler IC. The second optocoupler drive and relay control circuit is used for power supply control of the first simulation host.

[0035] Although the third optocoupler drive and relay control circuit has the same structure as the first optocoupler drive and relay control circuit, it adds a resistor R61. One end of resistor R61 is connected to one end of resistor R52, and the other end of resistor R61 is connected to the positive terminal of the LED of the third optocoupler IC. The third optocoupler drive and relay control circuit is used for power supply control of the second simulation host.

[0036] In this embodiment, the power control board also includes a transistor-based switching circuit. This circuit includes a transistor Q11, resistors R47, R49, R48, and R50, and a capacitor C14. The collector of transistor Q11 is connected to a 12V power supply. The emitter of transistor Q11 is connected to one end of resistor R50 and one end of resistor R48, respectively. The other end of resistor R48 is connected to the base of transistor Q12, and the other end of resistor R50 is grounded. The base of transistor Q11 is connected to one end of resistor R47 and one end of capacitor C14, with the other end of capacitor C14 grounded. The other end of resistor R47 is connected to a start switch and one end of resistor R49, with the other end of resistor R49 grounded. Its main function is to use a small current / low voltage control signal to control the on / off state of a high voltage / high current power supply circuit; specifically, it uses a small 12V signal to control the on / off state of the 220V power supply connected to the relay contacts.

[0037] During operation, after turning on the air switch and pressing the start switch, the first optocoupler drive and relay control circuit is activated, controlling the first relay to close. This powers the display control unit via the power module and sends a start signal to the display control unit. Simultaneously, upon receiving the start signal, the display control unit outputs two I / O signals to the relays in the other two optocoupler drive and relay control circuits, controlling the power supply to the two emulators respectively. Pressing the start switch again disconnects the power to the display control unit from the first relay and sends a shutdown signal to the display control unit. Simultaneously, the display control unit outputs two I / O signals to the relays in the other two optocoupler drive and relay control circuits, controlling the power off of the two emulators respectively. The emergency switch's input and output bypass the power control board, directly controlling the power supply to the display control unit and the two emulators, ensuring the device can function normally even if the start switch fails.
