Intelligent Controller Design of Circuit-Breaker Based on Advanced RISC Machine Cortex-M3

Introduction was made to intelligent controller design of a new kind of open-construction circuit-breaker, which was con- trolled by the microcontroller STM32F103 based on the core of Advanced RISC Machine （ARM） Cortex-M3. Hardware and software design of intelligent controller was set forth. The hardware included modules of signals collection, microcontroller, power supply, communication, user＇s interface. This design is high in accuracy, good in real-time performance and easy to alter the protection mode setting of three-stage design. Modbus protocol was used in the equipment to realize remote control and communication.
