Abstract: This paper designed an online monitoring and control system of permanent magnetic vacuum circuit breaker based on dual microcontroller (MCU). This system adopted the distributed architecture and the hardware system took two chips of microcontroller,STC12C5A32S2 as its core, extending the touch screen, RS485 and RS232 as communication interface, to realize circuit breakers action control and measurement of bus bar voltage and current, contact displacement, capacitance voltage, discharging current etc functions. The PC monitoring software was designed with Microsoft foundation class (MFC) software and the system communicated with the MCU through the serial port to realize remote control. The experimental results show that the system has upper stability.
       Key words: permanent magnetic vacuum circuit breaker; microcontroller; online monitoring; communication
