Intelligent substation network message recording and analysis method and system

Abstract

The present invention disclosed a recording and analysis method and system of the intelligent substation network message, including: build the SCD file model; the receiving packets are optimized and stored;Data; based on the obtained message data data, online results analysis is performed.The present invention can improve the storage capacity of the packet, improve the reading method, reduce the damage of the disk by the magnetic head movement, improve the service life, improve user interaction, and save costs.

Description

technical field [0001] The invention relates to the technical field of communication message analysis, in particular to a method and system for recording and analyzing network messages of an intelligent substation. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, the analysis and display of the communication messages in the substation can check the integrity of the messages during the transmission process, which is convenient for judging whether there is frame loss during the communication process between devices and devices, and at the same time, analyzing the network connection status of devices and devices , providing strong support for the entire packet analysis. [0004] The network message analysis process in the substation is to use the network message analysis device of the intelligent substation to operate all the coll...

Problems solved by technology

In the process of reading and writing, the disk is damaged and the life is shortened, which is not conducive to economy and usability, and will also lead to high maintenance costs and obvious defects

[0005] When performing message analysis, the prior art analyzes the entire communication message collected to determine the integrity of the message and the bit error rate of the message; when performing message analysis, it is necessary to traverse the frame numbers in the entire message And judge the length of each frame of the message to determine whether the message is complete and whether there is a frame loss. Among them, if there is a message missing or out of sequence, it is necessary to traverse the internal sequence number of the entire message, the code reusability is not strong, and the work efficiency Low, high maintenance cost, heavy workload, resulting in a lot of waste of manpower and resources

[0006] When displaying messages, the existing technology parses the collected communication messages frame by frame and displays them in a list. It only parses and displays information such as the value and validity corresponding to the current channel in the message, but cannot visually display the multi-frame chain. Changes of channel data; when you need to view the numerical changes of channel values, you need to click each frame of the SV link to view the corresponding numerical changes. The work efficiency is very low, the display is not intuitive, and the user interaction is poor.
