Problems solved by technology

Therefore, it has been formed for a long time: once a new communication protocol appears or an extension based on the original communication protocol, it is necessary to modify or newly develop a communication protocol analysis program, which leads to a large number of low-level software repeated development, and the portability is relatively low. At the same time, frequent software upgrades also bury certain hidden dangers for the stability of the monitoring system

Embodiment Construction

[0045] figure 1 In order to use the protocol description language to describe the overall process of the communication protocol and analysis, after obtaining the text of the communication protocol, analyze the communication protocol, decompose the communication protocol into several communication processes, and decompose each communication process into one or more communication activities. According to the protocol Describe the grammar, convert each communication activity into a protocol script, and submit all the protocol scripts to the protocol script parsing module, the protocol parsing module of the communication management machine reads the protocol scripts of all communication processes, analyzes the grammatical structure, and creates the matching of the protocol scripts The method is to control and analyze the communication process according to the protocol script, and complete the data exchange with the electric power intelligent equipment. In order to make the implemen...

Abstract

The invention discloses a communication protocol script analyzing method of electricity intelligent equipment, defines a communication protocol description language and provides a corresponding analyzing method. The communication protocol script analyzing method of the electricity intelligent equipment comprises: firstly, decomposing a communication protocol into a plurality of communication processes after the communication protocol is received; secondly, decomposing every communication process into a plurality of communication activities, and converting the communication activities into protocol scripts according to the communication protocol description language; and lastly, analyzing the protocol scripts through a protocol script analyzer. By controlling and analyzing the communication processes according to the scripts, the data exchange of the electricity intelligent equipment can be achieved, so that the redevelopment of a communication protocol analyzing module can be avoided.

Description

Technical field: [0001] The invention belongs to the field of automatic communication management machines for electric power systems and factories and mines, and in particular relates to a script analysis method for communication protocols of electric power intelligent equipment. Background technique: [0002] With the continuous improvement of the automation level of power systems and factories and mines, more and more power intelligent equipment, such as DC screens, small current grounding, arc suppression, harmonic elimination systems, photovoltaic inverters, etc., need to be connected through local communication management machines. into the local monitoring system. Although standard protocols such as MODBUS, IEC103, and IEC61850 have been widely used, due to the different technical strengths of various smart device manufacturers, many of the communication protocols used are still self-defined or extended on the basis of standard communication protocols, even if some man...
