Communication and control method and system for external circuit breaker of electric energy meter

Abstract

The embodiment of the invention provides a communication and control method and system for external circuit breaker of electric energy meter. The method comprises the steps that terminal equipment obtains a circuit breaker identity identifier of a corresponding circuit breaker, and receives broadcast data from a plurality of electric energy meters; the terminal equipment analyzes the received broadcast data to obtain an electric energy meter identity identifier corresponding to each electric energy meter; the terminal equipment determines a corresponding connection electric energy meter from the plurality of electric energy meters based on a preset rule according to the circuit breaker identity identifier ; the terminal equipment sends a connection request to the connection electric energymeter, so that the electric energy meter establishes connection with the terminal equipment according to the received connection request; and the terminal equipment sends the circuit breaker identityidentifier to the connection electric energy meter, so that the connection electric energy meter establishes connection with the circuit breaker corresponding to the circuit breaker identity identifier according to the circuit breaker identity identifier.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a method and system for communication and control of an external circuit breaker of an electric energy meter. Background technique [0002] With the development of my country's electric power industry, the electric energy meter fee control system has become the basis of the smart grid, and has been widely valued by the grid company. The basis of the electric energy meter fee control system is the use of circuit breakers. The circuit breakers are installed in the electric energy metering box and used with electric energy meters. They are the key components of the electric energy meter charge control system. The energy meter can open and close the circuit breaker through the control signal line and the feedback signal line. [0003] In the prior art, a wired connection is often used between the electric energy meter and the circuit breaker to realize the control ...
