Communication expansion method based on interconnection and intercommunication broadband carrier

Abstract

The invention discloses a communication expansion method based on interconnection and interworking broadband carriers. The method comprises the following steps: S1, selecting a transformer area; s2, on-site transformation is carried out, a gradual transformation mode is adopted, and two communication modes coexist during transformation; and S3, mixed meter reading. According to the invention, 485 channel data of the concentrator is modulated into interconnection and intercommunication broadband carrier channel data to communicate with an interconnection and intercommunication broadband carrier scheme electric energy meter, so that the problems of single centralized reading scheme of the original equipment and incompatibility of different communication technology protocols in a single transformer area are solved, the collection success rate is ensured, and the cost is reduced. The improvement cost of installing two concentrators or replacing an electric energy meter communication module is avoided, and marketing asset management is facilitated.

Description

technical field [0001] The invention relates to a communication expansion method based on an interconnected broadband carrier, belonging to the technical field of electric power communication. Background technique [0002] At present, there are various communication methods such as non-interconnected broadband carrier, interconnected broadband carrier, narrowband carrier, dual-mode, and micro-power between the concentrator and the electric energy meter in the low-voltage station area of ​​the power grid in Guizhou. Only one communication method can be used between tables, and different communication methods cannot communicate with each other. [0003] In various communication modes such as non-interconnected broadband carrier, narrowband carrier, dual-mode, micropower, etc., it is necessary to install corresponding non-interconnected broadband carrier, narrowband carrier, dual-mode, micropower and other communication modules in the concentrator and the energy meter at the sa...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a communication expansion method based on interconnection and intercommunication broadband carrier, so as to solve the problem that different electric energy meters in the same station area are mixed with multiple communication methods, resulting in a low success rate of user electric energy meter collection, which is inconvenient for marketing Asset Management Issues
