摘　　要：针对目前永磁机构真空断路器控制器的单一微控制单元(micro control unit,MCU)处理任务多、运行速度慢、故障率较高等现状,设计了一种新型的10 kV永磁机构真空断路器智能控制器。该控制器分为电源、保护和通信三大模块,分别设有单独的MCU实现相应的功能。硬件方面,保护单元以STM32f407单片机为微处理器,主要负责信号采集、处理、保护等功能,2片STM32f103单片机分别作为电源管理、通信及人机交互部分的硬件核心;软件方面,将μC/OS-Ⅱ实时操作系统和TCP/IP协议移植到该系统中,使系统具备高度的稳定性与实时性。经测试新型控制器的可靠性以及运算速度、精度都较旧型器有很大的提升,同时降低了故障率。According to the status of single micro control unit （MCU） of vacuum circuit breaker controller with permanent magnetic actuator： many processing tasks, slow running speed, higher failure rate and so on, this paper designed a new type of smart controller for 10 kV vacuum circuit breaker with permanent magnetic actuator. The controller was divided into three modules ： power, protection and communication, and each had MCU respectively to achieve corresponding functions. In terms of hardware, the protection unit used STM32f407 MCU as microprocessor, which could achieve the functions of signal acquisition, processing, protection and so on; two STM32f103 MCUs were used as the core hardware of power management, communications and human-computer interaction. In terms of software, μC/OS-Ⅱ real-time operating system （RTOS） and TCP/IP protocol were ported to the system, which could have a high degree of stability and real-time. The test results show that the reliability, computing speed and accuracy of the new controller have been greatly improved, and at the same time, the fault rate is reduced.
