Method for remotely communicating main station system and local communication module of concentrator

Abstract

Disclosed is a method for remotely communicating a main station system and a local communication module of a concentrator. Under existing technical conditions and communication protocols, the method for indirectly communicating the main station system of an upper computer and the local communication module of a far-end concentrator by the aid of a function of transparent transfer of the concentrator is provided, so that the main station system of the upper computer can interact with the local communication module of the concentrator directly. By the time-saving and labor-saving method, parameter setting and remote updating of the local communication module can be achieved, an operator does not need to go to mounting areas of the concentrator to set or update the local communication module, work load of field maintenance is reduced greatly, work efficiency is further improved, and operation and maintenance costs are reduced.

Description

technical field [0001] The invention relates to the field of power system communication, in particular to a method for remote communication between a master station system and a local communication module of a concentrator. Background technique [0002] In the electricity consumption information collection system of electric power users, the State Grid Corporation of China has mainly promulgated two kinds of communication protocols at present, one is "GB376. The other is "GB376.2 Concentrator Local Communication Module Interface Protocol", which is mainly used in the communication between the concentrator and the local communication module. The local communication module generally refers to the concentrator's carrier or wireless meter reading routing module . At present, each carrier routing module manufacturer has extended the 376.2 protocol, including the setting and reading of various extended parameters, and the local upgrade function of the carrier module by extending ...

AI Technical Summary

Problems solved by technology

At present, each carrier routing module manufacturer has extended the 376.2 protocol, including the setting and reading of various extended parameters, and the local upgrade function of the carrier module by extending the 376.2 protocol. They are not the same, and some extensions are the internal extensions of the carrier manufacturers, which are not publicly disclosed, resulting in the concentrator not being fully compatible or compatible with the extended protocol parts of each carrier manufacturer. For this situation, the current usual The method is to require professional technical engineers to go to the site where the concentrator is installed, and directly interact with the local communication module of the concentrator through certain technical means, so as to achieve the purpose of setting parameters or upgrading
