摘　　要：随着电力工业的发展,电力供应的可靠性和电能质量越来越多地受到关注,对电力参数的检测也提出了更高的要求。研制了以单片机与DSP双CPU并行处理技术为基础的电力监控装置。该装置采用交流直接采样技术,充分利用87C196CB单片机的硬件资源和DSP强大的运算能力,并尽可能采用软件代替硬件,具有可靠性高、数据刷新速度快、关键信息不丢失等特点。还配置有串行通信接口和CAN现场总线接口,可方便地与计算机或其它电力监控装置通信,该电力监控器可以代替多种电力测量仪表、功率因数表及负荷控制器等实现电力系统的远程监控功能。With the development of electric industry, power supply reliability and power quality have been put more and more attention, and more effective monitoring equipment are needed to detect the power parameters. Using single chip microprocesser and DSP parallel processing technology, this paper designs power monitor equipment. The newly designed monitor uses the technology of AC sampling directly, exerts the hardware resource of 87C196CB and the capability of powerful data processing of DSP, and employs software instead of hardware as possible. So it has the merits of high reliability and data-update speed without losing key messages. It has both serial and CAN bus communication interface, which make it easy to communicate PC and other monitor equipment, so the power monitor can replace many kinds of power measure meters, power factor meter and burden controllers to perform the function of remote monitoring.
