[0023] Example:

[0024] To address the problems of complex operational processes and low manual efficiency, this invention provides an intelligent simulation verification device for railcar equipment. The device includes a computer unit, a railcar unit, an analog signal unit, and a power supply unit. The railcar unit is equipped with CAN3 and CAN4 connectors for communication and data transmission between the device and external systems. The computer unit includes an industrial control computer (ICC) and an LCD display. The ICC connects to the LCD display via a touchscreen interface, allowing users to operate and monitor the system, greatly simplifying its use. By integrating multiple functional modules, this invention achieves intelligent simulation and data verification of railcar equipment, effectively improving work efficiency and reducing errors and inconvenience caused by manual operation.

[0025] The industrial control computer uses an x86 Windows system, designed to handle complex data interpretation, verification, and image display tasks. Based on Windows, the industrial control computer not only possesses powerful computing and processing capabilities but also easily interfaces and integrates with other software systems, ensuring the accuracy and reliability of data verification. It can also display the real-time operating status of the equipment and various parameters and image information during the simulation process, which users can clearly and intuitively view on an LCD screen. The railcar unit includes a main control board, communication recording board, output board, and DMI baseboard. These boards perform different functions: the main control board is responsible for the core control and management of the entire system; the communication recording board records and analyzes the data flow during communication; the output board transmits analog or control signals to external devices; and the DMI baseboard is used for interface management and data integration. Through the coordinated operation of these boards, the entire system can perform comprehensive simulation verification of the railcar equipment, ensuring that the equipment maintains a stable and efficient working state during actual operation.

[0026] In addition, the analog signal unit generates various analog signals to simulate the operating state of the equipment under different working conditions, thereby verifying the equipment's response and performance in different scenarios. The power supply unit provides a stable power supply to the entire intelligent simulation verification device, ensuring that all parts of the system can operate normally.

[0027] In summary, this utility model, through the close integration of the computer unit and the railcar unit, and with the support of the analog signal unit and the power supply unit, realizes efficient and intelligent simulation verification of railcar equipment, solves the problems of cumbersome operation and inefficiency in the traditional disclosure process, and greatly improves work efficiency and data processing accuracy.

[0028] The analog signal unit comprises a main control board, a vehicle signal board, and a motherboard. The motherboard connects the analog signal unit and the railcar unit. The analog signal unit simulates various signal systems, uplink / downlink traffic conditions, operating conditions, locomotive signal light types, speed, pipe pressure, and braking status. It also receives signals from the railcar unit, such as pressure holding, normal operation, emergency, engine shutdown, and unloading, and executes related actions. The DMI baseboard controls and displays the entire DMI. DMI button control is achieved by sending button data to the DMI via a serial port, while control of the analog signal unit is achieved via Ethernet. The DMI display is achieved by an industrial computer acquiring the HDMI signal output from the DMI. The analog signal unit's external interfaces include a GMS interface, an expansion communication interface, an analog signal unit USB port, and a DMI USB port. The DMI USB port uses a USB switching circuit to automatically upgrade display data. Figure 2 As shown, the USB control circuit is connected to the DMI by default. When there is display data that needs to be upgraded, a USB flash drive is connected to the USB port, and the USB is switched to the industrial control computer through the GPIO port of the industrial control computer. The display data is stored in the USB flash drive, and then the USB flash drive is switched to the DMI to upgrade the display data by sending simulated button data.

[0029] The LCD display is a crucial component of this intelligent simulation verification device. It not only provides a display function but also integrates a touch module, further enhancing the convenience of human-computer interaction. The LCD display includes an LCD screen with a touch module and a human-computer interaction interface, enabling users to operate and interact with the system intuitively and conveniently.

[0030] The human-computer interface features virtual buttons, which allow users to input commands via touch on the screen. Unlike traditional physical buttons, virtual buttons can be simulated and defined by computer programs, offering high flexibility. Users simply touch the buttons on the screen, and the system simulates the button signals through the computer unit, thereby driving the device to perform the corresponding operation.

[0031] This touch-based operation allows users to easily access basic data from the device, further simulating its operation and verification. In practice, users can utilize these virtual buttons to manage various device functions, view operating status, and adjust parameters, greatly simplifying the operation process and enhancing system usability and human-computer interaction. Furthermore, the introduction of the touch module reduces reliance on external control devices, making the system more integrated and intelligent.

[0032] The industrial control computer unit's communication interfaces include two CAN channels, one HDMI channel, one RS422 channel, one RS232 channel, and one LAN channel. The analog DMI communicates with the railcar unit board, and automated testing is achieved through host computer software. The LAN channel connects to the analog signal unit to execute analog signal commands. The design and configuration of these interfaces enable the system to perform various forms of communication and control operations, thus supporting complex automated testing processes.

[0033] Two CAN communication channels connect to CAN3 and CAN4 to simulate communication between the DMI and the railcar unit board, and automated testing is achieved through host computer software. One RS422 channel connects to the analog signal unit, simulating BTM host signals for communication with the analog signal unit via a computer. One HDMI channel connects to the computer unit to capture the actual image output from the DMI and display it on the screen. One RS232 channel connects to the railcar unit to simulate DMI button operations.

[0034] First, two CAN interfaces are used to connect to the CAN3 and CAN4 buses in the railcar unit, respectively. These two CAN buses are responsible for communicating with the core boards of the railcar equipment, ensuring data exchange and synchronous operation between devices. This communication method is widely used in industrial automation equipment and has advantages such as strong anti-interference and high communication efficiency. Through this interface, the industrial control computer can directly transmit data with the railcar unit boards, and work with the host computer software to realize automated testing tasks, greatly reducing the complexity and error of manual operation.

[0035] Secondly, a LAN interface is used to connect to the analog signal unit. The analog signal unit is responsible for generating various analog signals to test the equipment's response and performance under different operating conditions. Through the LAN interface, the industrial control computer can send commands to the analog signal unit to execute various analog signal generation and control tasks. This connection method ensures the stability and high speed of signal transmission, enabling the system to maintain efficient operation in complex testing environments.

[0036] One RS422 interface also connects to the analog signal unit, used to simulate BTM (Balise Transmission Module) host signals via computer. This interface is used to simulate communication signals between trains and tracks in specific test scenarios. Through cooperation with the analog signal unit, the accuracy and reliability of signal transmission can be verified. The RS422 interface has a long communication distance and strong anti-interference capability in industrial communication, making it ideal for use in complex testing environments.

[0037] In addition, the industrial control unit is equipped with an HDMI interface, which is mainly used to connect to the computer unit. Through the HDMI interface, the industrial control unit can capture the actual images output from the DMI (Driver Machine Interface) and transmit them in real time to the LCD display. This allows users to intuitively view the equipment's operating status and various parameter information on the screen, thus better monitoring the entire simulation testing process.

[0038] One RS232 interface is used for direct communication with the railcar unit, primarily to simulate button operations on the DMI. Through this interface, the industrial control computer can control the virtual button operations on the DMI and simulate actual button input signals via computer. This design enables the entire system to automatically execute a series of operational steps without human intervention, achieving a fully automated testing process.

[0039] The audio signal from the industrial control computer is mixed by a power amplifier in the analog signal unit before being output. This process involves processing the audio signal generated by the industrial control computer using a specific circuit structure to ensure that the audio signal meets the required sound quality and volume requirements. Specifically, the industrial control computer, as the core control unit of the system, generates and transmits the audio signal to the analog signal unit, which is responsible for amplifying, mixing, and other processing operations on the audio signal. Through the amplification effect of the power amplifier, the intensity of the audio signal is enhanced, ensuring better and clearer audio output in practical applications. At the same time, the mixing function can synthesize multiple audio signals, allowing signals from multiple audio sources to be output collaboratively, thereby meeting the audio needs in complex scenarios.

[0040] The hardware and software of the railcar unit are consistent with those used in actual railway bureaus. This means that testing and debugging conducted in a laboratory environment can be seamlessly integrated with equipment in real-world application scenarios, ensuring high reliability and compatibility for use in critical infrastructure such as railway bureaus. The hardware design of the railcar unit covers multiple aspects, including signal processing and data transmission, while its software is responsible for controlling, monitoring, and optimizing the operation of the entire system. This tight integration of hardware and software ensures efficient operation of the equipment in practical applications and enables it to cope with complex and ever-changing field environments.

[0041] The industrial control computer (ICC) unit and the analog signal unit are connected, ensuring not only stable signal transmission but also seamless data exchange between different units. The ICC acts as the control core, coordinating the work of each unit, while the analog signal unit focuses on processing and outputting audio signals. This close collaboration enables the entire system to maintain efficient and stable operation in complex working environments. In practical applications such as railway bureaus, this connection and collaboration effectively meet on-site communication and control needs, ensuring system reliability and stability.

[0042] The power supply unit includes a power logic control system and a power supply system. The power control board, as the power control unit of the entire circuit board, enables safe shutdown. The power logic control principle is as follows: Figure 3 As shown, upon receiving a power-on signal, the logic circuit on the power control board controls relay 1 to engage, turning on the power to the industrial computer. This logic circuit maintains the power supply on. The power to the track vehicle and analog signal units is controlled by the industrial computer via relay 2. During shutdown, the industrial computer receives a shutdown signal through the logic circuit on the power control board, first shutting down the power to the track vehicle and analog signal units, and finally shutting down the industrial computer. The power supply system uses two switching power supplies with different output voltages: 12V for the computer unit and 24V for the track vehicle and analog signal units. These two units can be powered on and off independently.

[0043] This invention provides an intelligent simulation verification device for railcars. First, it ensures that the basic data set in the verification software is consistent with the basic data in the railcar simulation equipment; if inconsistent, the GYK data needs to be upgraded. Verification data is generated and compiled using verification editing software, downloaded to the DMI, and read by the software. After setting parameters, the verification data is automatically verified. Upon completion, the verification results are displayed and printed. Users can also query and export historical verification results, enabling automatic batch verification of railcar runs, significantly improving verification efficiency and meeting the time requirement of completing verification before release. Additionally, it features a railcar learning and examination function, automatically generating exam papers and allowing for querying and printing of exam results. When automatic verification is not performed, data can be manually retrieved, and pipe pressure, speed, operating conditions, and locomotive signal information can be set to simulate operation based on actual site conditions. The specific operation is the same as for railcars. Messages can also be sent sequentially to the DMI interface to achieve automatic BTM simulation verification.
