Abstract

The invention relates to the field of intelligent circuit breakers. The invention discloses an intelligent circuit breaker communication networking system, comprising a remote monitoring terminal, an RS485 / 232 converter, a Modbus communication module, a Modbus bus and an intelligent circuit breaker, and the RS485 / 232 converter is used as a remote monitoring terminal to communicate with the Modbus bus Interface to complete the conversion between the Modbus bus data level and the RS232 interface level. The intelligent circuit breaker includes a circuit breaker body and an intelligent controller, which is responsible for monitoring the status of the on-site line and performing breaking or closing operations, and through the communication interface. The Modbus communication module performs data interaction, and the Modbus communication module communicates with the remote monitoring terminal through the RS485 / 232 converter through the Modbus bus. The invention has stable communication, good real-time data interaction, strong anti-interference ability and wide versatility.

Description

technical field [0001] The invention relates to the field of intelligent circuit breakers, in particular to an intelligent circuit breaker communication networking system based on Modbus bus. Background technique [0002] As the basic component of low-voltage power distribution, the circuit breaker is responsible for the distribution and transmission of electric energy and the protection and control of electrical equipment, etc., and plays a pivotal role in the reliable operation of the power system; , in addition to the traditional functions, the circuit breaker also needs to realize real-time power quality monitoring, operation status monitoring, dynamic configuration and hierarchical protection functions. Therefore, high-speed, two-way, real-time and integrated technical requirements are put forward for the communication function of intelligent circuit breakers. However, in the long-term actual operation of the current intelligent circuit breaker, there are disadvantages ...
