摘　　要：针对高压断路器机械特性监测的具体要求,设计了基于ARM+DSP主从处理器架构的分布式监测系统。基于模块化系统设计思想,提出了由ARM核心板、DSP协处理板和信号处理模块组成的硬件实现方案。采用通用的设备驱动器模型和柔性的软件架构,开发了易于扩展和移植的DSP协处理器固件程序,运用Windows CE操作系统构建嵌入式Web Server的方法,结合ASP+COM组件技术,设计实现了基于Web技术的远程服务功能。该系统具有可靠性高、组态灵活、传输距离远、易于部署、扩展方便等特点,能够在线实时分析高压断路器机械特性的多个特征参量,基于Web页面的远程服务功能使得分布式监测系统的易用性和易维护性得到显著提升。The prototype for distributed monitoring system is brought forward according to the demand of online monitoring system for mechanical characteristic of high voltage breaker. In this solution, architecture of ARM as host processor and DSP as co-processor is embodied. The hardware platform based on modular design is presented, which consists of ARM core board, DSP co-processing board, and signal-modulated module. The firmware that can be easily transplanted and extended for DSP board is developed based on general module of device driver and flexible software structure. Remote service for distributed monitoring unit is implemented based on web technology. It embodies ASP and COM component technology, and is built upon ARM processor which is transplanted with Windows CE. This system has the characteristic of high reliability, flexible configuration, long-distance transmission, as well as convenient installation and extension and many characteristic parameters of mechanical conditions in high voltage breaker can be obtained through it. Remote service based on web technology can facilitate distributed monitoring maintenance and utility.
