Communication protocol record analysis apparatus and its analysis method

Abstract

This invention relates to communication rules record and analysis device and its method, which records all abnormal materials for each situation during whole process and provides record analysis device and method for back data analysis. This invention device is one distribution structure, which comprises each communication point recorder and one analysis management machine connected by single high speed Ethernet, wherein, series interface module, Ethernet interface module, CAN interface module, LONMORK module, GPS module output end are separately connected to CPU module input end.

Description

technical field [0001] The present invention is a recording and analyzing device and analysis method for providing reliable data for future analysis of accident causes by recording the first-hand on-site data of various abnormalities and faults through recording the entire communication process. The invention belongs to the technical field of the conformity test of the telecontrol protocol between the dispatching master station and the plant station by the maintenance personnel of the dispatching master station of the electric power system. Background technique [0002] With the continuous development of electronic technology and computer technology, the intelligence level of the secondary equipment of the power system is continuously improved, so that the communication ability between the equipment is becoming more and more important in the substation automation system and dispatching automation system. Judging from the actual situation of the current substation automation ...

AI Technical Summary

Problems solved by technology

In terms of secondary equipment, since there is no relatively uniform specification, each power equipment supplier acts independently and forms its own system, and has its own communication specification, which causes great inconvenience to power users and affects the safe and stable operation of the entire power grid. is also a disadvantage

[0004] 2. The technical strength of power equipment suppliers is different, resulting in different robustness and realization of communication functions of power automation products

[0006] 3. The data at the moment of abnormality and failure are not recorded

There is no original record in the current automation system, and the cause of the fault can only be inferred by querying the processed data at the system end, so it is impossible or difficult to find out the real cause of the fault

[0007] 4. Security issues

With the continuous update of power communication technology and the popularization and application of the Internet, the issue of network security has increasingly become a problem that needs to be considered. At present, there is a lack of monitoring records for data exchange on the network, which is not conducive to the control and analysis of network security.
