Description

Technical Field

[0001] The present invention relates to the field of rail transportation, and in particular to a software deployment method, system and medium for a driver human-machine interface screen. Background Art

[0002] In the field of rail transit, the driver machine interface (DMI) screen is a key device for the interaction between onboard equipment and the driver. DMI usually consists of two parts: display hardware and supporting software, which together realize the display of driving information and the input of operating instructions.

[0003] At present, the software and data installation and deployment of DMI display screens are often carried out through Ethernet. However, there are many inconveniences and problems in this deployment process. During the first installation, the operator needs to get on the vehicle and manually install the software, deploy the data, and set up the system according to the specific model, operating system, and other information of the DMI device. This method is not only time-consuming and labor-intensive, but also requires high professional skills of the operator and is prone to errors.

[0004] To make matters more complicated, due to the particularity of the rail transit field, there are many types of DMI equipment, and they are often customized according to various actual needs. This customized production method leads to significant differences between different equipment, which are specifically manifested in the following aspects:

[0005] 1. Different initial IP addresses when leaving the factory: Different batches of DMI devices may be assigned different initial IP addresses when leaving the factory, which increases the complexity and error rate during installation and deployment.

[0006] 2. Different terminal connection and file transfer protocols: Different DMI devices may support different terminal connection (such as telnet, ssh) and file transfer (such as ftp, sftp) protocols, which requires operators to be proficient in the use of multiple protocols, increasing the difficulty of operation.

[0007] 3. Different software and data packages: Since DMI devices may run on different operating systems, or even if the operating system is the same, there may be differences in software and data packages due to factors such as dependency libraries. Such differences make software deployment complex and difficult to unify.

[0008] 4. Different system settings: For the same model of trains running on the same line, the system IP and routing settings of the DMI device may also be different depending on the train number. If the settings are wrong, the device will not be able to communicate with the on-board system, affecting the normal operation of the train. Summary of the invention

[0009] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a software deployment method, system and medium for a driver human-machine interface screen, which reduces the steps of manual input and configuration, improves the accuracy and efficiency of deployment, and reduces the requirements for the professional skills of operators.

[0053] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0055] Driver Machine Interface: Driver Machine Interface, DMI

[0056] Internet Control Message Protocol: Internet Control Message Protocol, ICMP

[0057] Transmission Control Protocol: Transmission Control Protocol, TCP

[0058] Example 1

[0059] This embodiment provides a software deployment method for a driver human-machine interface screen, such as Figure 1 As shown, the following steps are included:

[0060] S1. Scan the connected DMI device through the ICMP LAN host to determine the device address of the connected DMI device.

[0061] The steps to confirm the device address of a connected DMI device include:

[0062] Enter the initial IP address range of the device or use the built-in IP address of the tool. The software automatically selects to construct an ICMPECHO Request packet and sends it to the initial IP address of each model of DMI device. Based on the feedback ICMP ECHO Reply packet, the device address of the connected DMI device is determined.

[0063] like Figure 2 As shown, the initial IP address is set in a wizard-like manner, including two modes: using the built-in IP table in the software configuration file or entering an IP address range, such as entering 10.92.1-86.146.

[0064] S2. Sniff the available connection protocols through TCP full connection scanning, and establish the terminal control connection and file transfer connection of the connected DMI device.

[0065] You can use the connection protocol sniffing to perform TCP connection to the port of the connected DMI device through TCP full connection scanning, and establish the terminal control connection and file transfer connection of the connected DMI device based on the successfully connected port. Figure 3 As shown in the figure, perform port tests on each host: first, perform a TCP three-way handshake connection test on port 22 of the target host. If the connection test is successful, use ssh and sftp to establish a terminal control connection and a file transfer connection. If port 22 cannot be connected, continue to perform TCP three-way handshake connection tests on ports 20, 21, and 23 respectively. If all three ports can establish connections, use telnet and ftp to establish a terminal control connection and a file transfer connection. If any connection fails to be established, the corresponding port status and connection status information will be given on the upper computer graphical interface.

[0066] The terminal control connection includes a telnet connection or an ssh connection, and the terminal control connection is implemented through the telnetlib library and the Paramiko library.

[0067] File transfer connections include ftp connections or sftp connections, which are implemented through the ftplib library and the Paramiko library.

[0068] S3. Identify the device model and operating system of the connected DMI device through the terminal control connection, and determine the correct software version and data version.

[0069] The DMI devices supported by the present invention can obtain specific model information in the device information. The device model and system identification process are as follows: Figure 4 As shown, first send the uname-s command provided by POSIX through the control connection. If the command is executed successfully, proceed to the next step according to the operating system name in the standard output stream. If the command fails, it means that the target host may be running the Windows operating system. The control connection sends the ver command to verify whether the target host is Windows. If the host is a Linux or QNX operating system, send the uname-r command and uname-n command through the control connection, and search for keywords of the model name in the standard output stream, such as TX2037, HTWY, etc., to determine the device model.

[0070] like Figure 5 As shown, the software version, data version, and DMI device model to be deployed are displayed on the upper computer graphical interface, and the operator selects the train number, the first and last ends of the train, and other information and confirms it again. If the information is confirmed to be incorrect, the operator can choose to deploy some devices or go back to the previous step and scan again.

[0071] S4. Upload and expand the software package and data packet through the file transfer connection, set the operating system according to the device address, and complete the software deployment for the confirmed connected DMI device.

[0072] When setting up the operating system, upload the tar package, tar.gz compressed package, and zip compressed package to a temporary folder through the file transfer connection and decompress it to the DMI path of the device root directory.

[0073] Write the commands for setting the device address and route into the operating system startup script and network configuration file, send the software's built-in setting script through the terminal control connection and execute it to complete the operating system setting.

[0074] The specific software deployment process in this embodiment is as follows Figure 6 As shown in the figure, the control connection sends the slay or killall command (depending on the operating system) to stop the application; upload the software and data packets to the temporary directory of the DMI device through the file transfer module; call the corresponding decompression command under the control connection to extract them to the root directory of the device; execute the corresponding system setting scripts in sequence. If the above steps are completed successfully, the deployment is successful. If a step fails, the execution stops, the deployment fails, and the execution print log is displayed.

[0075] The operation results of each step of software deployment are displayed on the upper computer graphical interface. For steps with failed operation results, the upper computer graphical interface will display the operation log and error prompt information, which will help operators quickly locate the problem and take corresponding solutions.
