Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of interlocking system data accuracy detection method based on version verification in order to overcome the above-mentioned defective existing in the prior art, judge by its CRC check value, the configuration file and data file that it uses Whether the content is consistent with what is expected, and whether the expected software version is used is determined by checking its version number. The method for confirming the correctness of the interlocking data in the present invention can get rid of the inability to view the interlocking operation machine MMI online and the interlocking lower level It can realize the function of real-time online verification of MMI and IPS data and configuration files, and can verify the software version number of MMI and IPS; and further realize online configuration management, thus ensuring software , data and configuration files consistency, so that the interlocking system is more secure

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, this embodiment includes a set of station interlocking system: interlocking lower computer IPS, interlocking operation machine MMI, and interlocking maintenance station SDM.

[0024] Such as figure 2 As shown, the SDM sends a version request message frame to the IPS / MMI through the TCP protocol. After the IPS / MMI receives the version request message frame, it sends the calculated data file and the CRC check value and software version number of the configuration file to the SDM through the TCP protocol. After receiving the reply message, SDM compares the received CRC check value with the CRC check value calculated from the local archive file, and displays the comparison result and IPS / MMI software version number on the SDM interface.

[0025] Such as image 3 As shown, on the one hand, IPS / MMI receives th...

Abstract

The invention relates to an interlocking system data accuracy detection method based on version verification. The method comprises the following steps that (1) an SDM sends a version request message to an IPS / MMI; (2) after receiving the request message, the IPS / MMI calculates a CRC value, used by a current node, of interlocking data and a configuration file and sends the CRC value and a version number of software of the IPS / MMI to the SDM; (3) after receiving a reply message, the SDM calculates a CRC value, backuped on a local disk, of the interlocking data and the configuration file of the IPS / MMI and compares the CRC value with the received CRC value; (4) if the two CRC values are equal, it is shown that a data file / configuration file adopted in a target node is consistent with a data file / configuration file backuped in the SDM, and a software version number of an opposite-side node is displayed on the SDM. Compared with the prior art, the interlocking system data accuracy detection method based on version verification has the advantages that the maintenance efficiency of field personnel is effectively improved, and the field personnel are not prone to making mistakes during project implementation.

Description

technical field [0001] The invention relates to a method for detecting interlocking system data, in particular to a method for detecting the accuracy of interlocking system data based on version verification. Background technique [0002] A complete set of interlocking system includes interlocking lower computer IPS, interlocking operation machine MMI, and interlocking maintenance station SDM. Each interlocking node device uses its own interlocking system software as well as data files and configuration files. Interlocking maintenance personnel need to check the software version numbers, data files and configuration files of all equipment interlocking systems at any time. Among them, the data, configuration files and programs of the interlocking lower computer IPS cannot be viewed after burning into the VLE chip. Although the data, configuration files and programs of the interlocking operation machine MMI can be viewed, it is inevitable to make mistakes when switching machi...
