Communication protocol conversion method for master station in power system

Abstract

The present invention discloses a communication protocol conversion method for a master station in a power system. The method comprises that according to a communication protocol, user data is decomposed as data segments in accordance with function types; data type definiteness is carried out on the data segment to obtain a data model; the data model is matched with the communication protocol, and an XML configuration file is formed and annotated according to the matched data model; according to a user data identification, the XML configuration file is loaded, and the data segments are traversed to obtain a matching result; and the master station loads the XML configuration file according to the user data identification of the communication protocol needing to be converted, so as to obtain the matching result of the XML file and the data segments. The method disclosed by the present invention is applicable to all types of communication protocols, especially to the occasions of complex communication data, complex communication protocols, or communication protocols needing to be frequently converted; and the method is simple and easy to operate, and can rapidly complete conversion of the communication protocol.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a communication protocol conversion method of a main station of a power system. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source for people's production and life. As an instrument for measuring electric energy, the electric energy meter is distributed at each end user nearby to measure the user's electricity consumption and upload data, which is convenient for the power system personnel to conduct statistics on electricity consumption and collect electricity charges. [0003] At this stage, remote meter reading technology has been widely used in power system meter reading. Each terminal device transmits the information of each terminal device to the master station through a certain communication protocol through a common s...

AI Technical Summary

Problems solved by technology

The existence of so many protocol versions makes it extremely difficult to develop the communication system of the power system master station, which cannot be applied to multiple types of communication protocols, and once the protocol supported by the communication system needs to be modified, the later expansion of the master station communication system and The maintenance workload is huge and the cost is extremely high

[0005] At present, the general method of protocol processing is: analyze or package the binary data stream according to the frame structure combination of message header, address field, user data identifier, user data, and message trailer; but for the processing of complex user data However, it is extremely difficult. The general protocol processing method is often due to the variety of user data types and large differences in formats. It can only design a data structure for each type of data, which cannot be generalized and configurable.
