摘　　要：开发了一套断路器运行状态在线监测系统,能实现包括机械、绝缘、温升等多种断路器运行特性的综合监测。该系统采用上、下位机结构,下位机是一个基于96单片机的数据采集系统,并拥有简单的人机接口,硬件设计中采用了PSD器件,大大提高了软件维护的灵活性。基于任务调度的下位机软件结构,保证了系统的稳定性和实时性。上位机实现数据的存储、状态量的显示和波形的显示;上下位机之间采用485串行通讯总线进行通讯。The designed system is capable of on-line monitoring the temperature rise, insulation and mechanical characteristic of circuit breakers. It has a local monitoring unit and a computer, the former collecting local data and showing users the condition report on LCD, indicating the condition of exceeding the threshold value that can be preset by user through keyboard, and sending the data to computer through RS-485 communication interface. The application of PSD device and a software method called task schedule makes the local monitoring unit more stable and more flexible.
