Technical Field

[0001] The invention relates to the maintenance and upgrading of monitoring equipment, and in particular to a system for remote burning of MCU software supporting status display in a railway system. Background Art

[0002] Monitoring systems are widely used in my country's existing railway systems. However, due to the special environment of the railway system, monitoring equipment is often large in number and widely distributed. During the use of the system, these devices need to be continuously upgraded according to user needs. How to upgrade the software of these devices is a difficult problem.

[0003] The upgrade method of the railway monitoring equipment software system is also gradually evolving. From the initial time-consuming and manpower-consuming upgrade by dedicated personnel to the equipment, to the basic stateless display remote upgrade, there are still problems such as inconvenience and non-intuitiveness in use.

[0005] The object of the present invention is achieved in this way, and relates to a system for remote burning of MCU software supporting status display in a railway system: It includes one or more monitoring information sources (including MCU), a monitoring server, and one or more monitoring terminals.

[0006] The monitoring information source and the monitoring server transmit information in both directions, and the monitoring server and the monitoring terminal transmit information in both directions.

[0007] The monitoring information source has two working modes, normal mode and upgrade mode. In normal mode: monitoring information is generated or output; in upgrade mode, software upgrade is performed; The monitoring server is used to collect monitoring information from monitoring information sources; send data to monitoring information sources, receive monitoring terminal data, and publish data to monitoring terminals; The monitoring terminal provides a user interface, sends data to the monitoring server, and receives data from the monitoring server.

[0008] When the software is burned to the MCU remotely, the monitoring server sends the upgraded software to the monitoring information source, the monitoring terminal subscribes to the software upgrade status message from the monitoring server, displays the upgrade status according to the upgrade status message, and the monitoring information source sends the software upgrade status message to the monitoring server. The specific workflow is as follows: Monitoring terminal: 1) Open the monitoring terminal; 2) Monitor the "Software Upgrade Status Event" topic and notify the monitoring server; 3) The operator selects the device to be upgraded and the upgrade version, and submits the upgrade task; 4) Wait to receive the monitoring server's upgrade status information for the monitoring information source, and change the status on the interface after receiving it.

[0009] Monitoring Server: 1) Confirm the monitoring terminal's notification of starting monitoring; 2) After receiving the upgrade task from the monitoring terminal, send a "start upgrade command" to the corresponding monitoring information source; 3) After receiving the "Start Upgrade Command Confirmation" from the monitoring information source, send the upgrade status information to the "Software Upgrade Status Event" topic, and start sending the upgrade file and file verification code to the monitoring information source; Cut the upgrade file into file slices according to a fixed size, number them in order from small to large, and send them to the monitoring information source in the format of "upgrade file slice content" frame one by one; The "Upgrade File Slice Content" frame includes: 1. Total number of file slices; 2. Current file number; 3. File slice content; 4. File slice content verification code; 4) After receiving the "Confirmation of File Batch Receiving" from the monitoring information source, send the upgrade status information to the "Software Upgrade Status Event" topic according to the file sending progress; 5) After receiving the "file verification passed message" from the monitoring information source, send the upgrade status information to the "software upgrade status event" topic; 6) After receiving the "software upgrade completion message" from the monitoring information source, send the upgrade status information to the "software upgrade status event.

[0010] Monitoring information sources: 1) After receiving the "start upgrade command" from the monitoring server, enter the upgrade mode; 2) After receiving the "upgrade file slice content" from the monitoring server, save the file slice content and return the "file batch reception confirmation" signaling, where the number is the current file number in the received signaling; 3) After receiving all the upgrade file slices, assemble all the received file slices into one file in the order of numbering, and compare and verify with the overall file verification code. If it passes, a "file verification passed message" will be sent and the file will be burned 4) After burning is completed, enter the normal mode; likeFigure 3 As shown in the figure, the software upgrade status is divided into the following categories: 1) In preparation: preparing for upgrade; 2) Downloading: When downloading the burning file, the download progress is displayed in percentage; Whether all file slices are downloaded successfully, if successful, proceed to the next step, otherwise return to step 6); 3) Download successfully, burn the file; 4) Upgrade completed: Upgrade completed; 5) Upgrade failed: Upgrade failed.

[0011] The advantages of the present invention are: solving the problems of low efficiency, time-consuming and labor-intensive burning methods. The program can be upgraded remotely without going to the device location for upgrading; Multiple devices can be upgraded at the same time; You can check the upgrade status in real time; Good reliability.
