摘　　要：低压断路器是应用于供配电系统中的一种重要的开关电器。本文介绍以80C196KC单片机为核心的智能型断路器的硬件设计和软件实现。该断路器通过连接在单片机I/O口上的三位拨码开关,实现对断路器额定电流、脱扣方式的设定。通过RS-485接口与上位机相连,可由上位机设定断路器的额定电流、脱扣方式,并使上位机获得断路器的各种参数信息,控制断路器的工作状态。The low voltage circuit breaker is an important kind of switch used in power system. This thesis introduces the hardware design and the software realization for the intelligent circuit breaker on the central of microprocessor 80C196KC. Through three bits dial switches connecting on the input or output interface of the microprocessor, the circuit breaker can set rated current and breaking mode. Moreover,the interface RS-485 which is used to communicate the circuit breaker with the upper computer is set, through this interface the upper computer also can set the rated current and the breaking mode, and the upper computer can get multi parameters information, control the working state of the circuit breaker.
