Intelligent miniature circuit breaker based on Zigbee wireless communication

Abstract

The invention provides an intelligent miniature circuit breaker based on Zigbee wireless communication. The intelligent miniature circuit breaker includes a power supply module, an electric quantity detection module, a relay output module, an MCU control module, a Zigbee wireless communication module and a buzzer alarm module. According to the intelligent miniature circuit breaker device, power consumption information of a user is measured, and then the power consumption information of the user is sent throughZigbee wireless communication or a control command of the user is received throughZigbee wireless communication. The power consumption information of the user includes a voltage, an electric quantity, a power, a power factor and the like; the control command of the user is mainly used for completing controlling over the on-off state of the intelligent miniature circuit breaker by the user. Moreover, when the intelligent miniature circuit breaker detects that the current of the device is too large, a to-be measured circuit is cut off by controlling the relay module and an audible alarm is given, so that the intelligent miniature circuit breaker ensures the electrical safety of the rear end of the intelligent miniature circuit breaker device and reminds the user that the electricity failure of the rear end of the intelligent miniature circuit breaker device causes the off state of the to-be measured circuit of the device.

Description

technical field [0001] The present invention relates to an intelligent miniature circuit breaker device, in particular to an intelligent miniature circuit breaker device based on Zigbee communication protocol capable of realizing wireless communication, that is, an intelligent miniature circuit breaker device based on Zigbee wireless communication. Background technique [0002] Energy issues are the core issues restricting the national economy today, among which electric energy is the most important, and how to save electricity is the core of today's research. With the promotion of smart grid and the implementation of national ladder electricity price, scientific electricity use has been paid more and more attention by electricity users. If power users can keep abreast of the power consumption information of their various devices at any time, then power users can reduce the burden on the power supply system, protect the environment, and save electricity costs by saving elect...
