Circuit breaker topology network identification method, circuit breaker, device and system

Abstract

The invention provides a circuit breaker topology network identification method, a circuit breaker, a device and a system, and relates to the technical field of low-voltage electric appliances. The method comprises the following steps: sequentially sending a control instruction to a plurality of circuit breakers according to a preset time interval, wherein the control instruction is used for instructing the circuit breakers to send topology signals; recording the time of sending the control instruction, wherein the time is used for indicating the sending time of sending the topology signal by the circuit breaker; sending a reading instruction to the plurality of circuit breakers; receiving record data fed back by the plurality of circuit breakers according to the reading instruction, wherein the record data comprises identification time when a topological signal of a lower-level circuit breaker is identified; and identifying and acquiring the topological network according to the recorded data and the locally recorded sending time. By recording the topology signal identification time of each subordinate circuit breaker in the circuit breaker and locally recording the topology signal sending time of the circuit breaker in the upper computer, the frequency of data acquisition from the circuit breaker by the upper computer can be effectively reduced, and the identification efficiency of the circuit breaker topology network is effectively improved.
