Dynamic plug-in type protocol parsing method of substation equipment

The invention discloses a dynamic plug-in type protocol parsing method of substation equipment. The method includes the steps of (1) initialization, wherein configuration initialization of coefficients of measuring points is conducted, and initialization of commands issued by the protocol is conducted, (2) waiting to send a command, (3) message authentication, (4) message parsing and (5) obtaining the equipment address. According to the dynamic plug-in type protocol parsing method, the problem of new equipment on-line is solved by additionally arranging a plug-in program related to the equipment protocol under the situation that an acquisition framework program is not revised, and using whiling plugging is achieved in a true sense. A dynamic protocol parsing technology divides development into two parts, one is application platform and the other part is a function expansion or supplement module, namely a dynamic plugin. A plugin interface is completely achieved through a plugin, and the application platform only responds for calling and using. The plugin interface is one-way communication of the application platform in the plugin direction, the platform calls the function achieved by the plugin through the plugin interface, and the protocol parsing is conducted.
