Communication system for intelligent miniature circuit breaker and control method thereof

Abstract

The invention discloses a communication system for an intelligent miniature circuit breaker and a control method thereof, belonging to the technical field of low-voltage circuit breaker control. The communication system comprises a power supply module, a communication module, a control module, an indication module, a first wireless module, a second wireless module and a power supply output module; the two wireless modules work simultaneously; the control module is used for processing received data, and sending the data to the intelligent miniature circuit breaker; when one wireless module cannot normally work, the control module can cut off the power supply of the abnormal wireless module through the power supply output module, and give an alarm through the indication module to remind a person to replace the abnormal wireless module; and thus, the system can work continuously and stably.

Description

technical field [0001] The invention discloses a communication system of an intelligent miniature circuit breaker and a control method thereof, belonging to the technical field of low-voltage circuit breaker control. Background technique [0002] With the development of circuit breaker technology, miniature circuit breakers are becoming more and more intelligent, and the monitoring of smart miniature circuit breakers is also being strengthened. Wireless communication modules can realize this function. Generally, each smart miniature circuit breaker is equipped with only one wireless communication module. , but due to the complexity of the industrial site situation, in order to ensure the reliability of on-site data monitoring, wired communication and wireless communication can be arranged at the same time, for example, CN201210244003 discloses a wired and wireless hot standby redundant multi-master communication method and on-site network node The module uses a wired plus wi...

[0002] With the development of circuit breaker technology, miniature circuit breakers are becoming more and more intelligent, and the monitoring of smart miniature circuit breakers is also being strengthened. Wireless communication modules can realize this function. Generally, each smart miniature circuit breaker is equipped with only one wireless communication module. , but due to the complexity of the industrial site situation, in order to ensure the reliability of on-site data monitoring, wired communication and wireless communication can be arranged at the same time, for example, CN201210244003 discloses a wired and wireless hot standby redundant multi-master communication method and on-site network node The module uses a wired plus wireless working method. When the wireless communication fails to work normally, it switches to wired communication. However, this method is expensive, and when switching the communication method, the monitoring center will not be able to collect on-site data. , and the communication interface between most products and communication equipment is single and irreplaceable, resulting in poor versatility of communication modules
