On-line monitoring system for the temperature of the contact of circuit breaker and busbar based on bluetooth technique

A monitoring piconet, which is made up of the circuit breaker contact monitoring system and the bus temperature monitoring system based on Bluetooth technique, is introduced in this paper. Using the contact-type method of measuring, the equipment temperatures in high potential are converted to wireless signals, which are transmitted to the center monitoring main-controlled computer directly. The systematic hardware circuit construction principle and the software realized methods of PC, SCM and Bluetooth module HCI interface are proposed.
