[0009] Preferably, in S4, when the validity check of various types of log data information and its format information is invalid, an alarm message is output to the engineering maintenance personnel, and after the alarm message processing is completed, S2 is turned to re-read the log data information generated by the train control center.

[0010] Preferably, in S5, if there is error log data information, an alarm message is output to the engineering maintenance personnel and an intelligent troubleshooting direction and solution are provided. After the error log data information is processed, the process goes to S2 and is read again.

[0030] Figure 1 It is a flowchart of a multi-faceted analysis method for a train control center maintenance log in an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 , the present invention is further explained by describing a preferred specific embodiment in detail.

[0032] It should be noted that the drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the embodiments of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present invention.

[0033] It should be noted that, in the present invention, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] like Figure 1 As shown, the present invention provides a multi-faceted analysis method for the maintenance log of a train control center, which specifically includes the following steps:

[0035] S1. The train control center maintenance log tool is powered on and started, and the parsing content template corresponding to the binary data information of the ciphertext is loaded in ciphertext form;

[0036] S2. The train control center maintenance log tool reads the log data information generated by the train control center;

[0037] S3, judging whether the log data information in S2 is read successfully; if yes, go to S4 and continue to run; if no, go to S2 and read it again;

[0038] S4, check the validity of each type of log data information and its format information in S3 to determine whether it is valid; if yes, go to S5 and continue running; if no, output alarm information to the engineering maintenance personnel, wait for the alarm information to be processed, and then go to S2 to re-read the log data information generated by the train control center;

[0039] S5. Classify, organize and merge each type of log data information that passes the validity check in S4 and then analyze the data information. If there is error log data information, output alarm information to the engineering maintenance personnel and intelligently provide troubleshooting directions and solutions. After the error log data information is processed, go to S2 and read it again; if it does not exist, end the operation.

[0040] Furthermore, in the above S1, the parsing content template corresponding to the binary data information of the ciphertext is loaded in ciphertext form, which can effectively prevent the erroneous data information analysis caused by the external intrusion and erroneous modification of the parsing content template.

[0041] Furthermore, in S4, the validity check includes checking of cyclic redundancy check (CRC), data length and message type.

[0042] Furthermore, in S4 and S5, the log data information generated by the train control center includes plain text system error information, cipher text binary data information, data information of each interface interaction and communication status information.

[0043] Furthermore, the plain text system error information includes verification word errors, virtual CD-ROM (VRD) errors, logical operation errors, virtual private server (VPS) errors, self-protection variable errors, drive collection errors, etc. that occur during the operation of the train control center system.

[0044] Among them, every time a check word error, VRD error, VPS error, or drive acquisition error occurs, an alarm prompts the engineering maintenance personnel that the system is running abnormally and there is a risk of downtime and restart; specifically: if it is a VRD error, it prompts to check the VRD relay; if it is a VPS error, it prompts to check the VPS board; if it is a drive acquisition error, it prompts to check the corresponding drive acquisition board; if it is a main check word error, it prompts to check the system logic operation board; if it is a re-check word error, it prompts to check the corresponding drive board and replace the board if necessary.

[0045] Each time a logic operation error occurs, an alarm is issued to remind the engineering maintenance personnel that the system is operating abnormally and that the logic operation board needs to be checked and manually restarted.

[0046] Every time a self-protection variable error occurs, an alarm will alert the engineering maintenance personnel that there is an abnormal synchronization between systems. They need to check the logic operation board and try to manually reverse the machine or restart it manually.

[0047] Furthermore, the binary system operation information errors of the ciphertext include inter-system synchronization data packet loss problems, data type / data length / source address / destination address verification errors in the communication protocol, message scrambling / descrambling errors, etc.

[0048] When analyzing the binary system operation information of the ciphertext, the quantity and frequency of different types of operation information in each time period need to be recorded. It is understandable that the key nodes of the system operation and the problems found in the operation process of this node are recorded in binary form.

[0049] When the frequency of packet loss of the inter-system synchronization data exceeds a certain threshold, an alarm message is output to the engineering maintenance personnel, prompting the engineering maintenance personnel that there may be network interference, network delay and other faults, so that they can intervene and deal with the fault point as soon as possible.

[0050] Among them, when the data type / data length / source address / destination address verification error occurs in the communication protocol, the time and number of occurrences should be recorded. When the above errors occur a certain number of times (such as 6 times) within a certain fixed time (such as 10s), an alarm message is output to the engineering maintenance personnel, reminding them that there may be network interference, network delays, hidden dangers in the communication board, and other faults, so that they can intervene and deal with the fault point as soon as possible.

[0051] Among them, the message scrambling / descrambling error is associated with the train speed limit position and speed limit size. When a message scrambling / descrambling error occurs, an alarm message is output to the engineering maintenance personnel to intervene and deal with the fault point as early as possible to avoid the message scrambling / descrambling error affecting the sending of the default message and affecting the train operation.

[0052] Furthermore, the data information of each interface interaction includes application data and process packages specified by the communication protocol for interaction between the train control center device and the external communication device; the communication status information includes the communication status of each communication connection device.

[0053] Among them, when analyzing the communication status information and the data information of the interaction of each interface, it is necessary to record the inspection results of different types of communication status and the corresponding process packages in the communication protocol. By combining the occasional errors in the communication protocol process package with the communication status information and dividing the time slices and error types, the communication status affected by different error types in each time period is analyzed, and the engineering maintenance personnel are promptly alerted to intervene and handle the problem.

[0054] It should be noted that, in a preferred embodiment of the present invention, the application data information of each interface interaction is analyzed to obtain error data that may affect the operation of the train control center, such as direction information, restart information, data recording freeze information, etc.

[0055] Among them, after obtaining the direction information, it is necessary to analyze the interlocking / temporary speed limit server interface. When it is found that the direction information sent by the backup system is no direction, an alarm will be issued to remind the engineering maintenance personnel that there is an inter-system synchronization interruption, resulting in the backup system sending no direction information, which will affect the message data and train driving. It is recommended to check the inter-system synchronization channel or replace the synchronous communication board.

[0056] Among them, after obtaining the restart information, it is necessary to analyze the timestamp in the server-sent events (SSE) data packet sent by the lineside electronic unit (LEU). When the timestamp changes from a large value to a small value, it can be determined that the LEU has restarted. Then an alarm will be issued to remind engineering and maintenance personnel of the LEU restart phenomenon and replace the LEU equipment in time.

[0057] Among them, after obtaining the data recording jam information, it is necessary to judge whether the data is jammed during the recording process based on the data recording time and the cycle number in the data packet, according to the principle of increasing every 500ms cycle. When data recording jams, an alarm prompts the engineering maintenance personnel to check whether the CPU usage of the industrial computer is too high and restart the industrial computer.

[0058] To sum up, the present invention provides a multi-faceted analysis method for the maintenance log of the train control center, which has the ability to process ciphertext and can protect against erroneous analysis caused by external intrusion; it can timely and reliably summarize and integrate the log data information, so as to intelligently analyze the analysis results and troubleshooting directions of the system from multiple angles and in multiple directions, so as to provide engineering and maintenance personnel with the opportunity to solve problems and reduce the scope of impact after problems occur; it can provide early warning and intervene in the processing of problems that may occur in the future found in the log data information, thereby eliminating unknown hidden dangers, and has great practical value.
