摘　　要：设计一种具有可编程、自动化测量、智能分析、数字通讯等功能的智能三相综合电力参数监测系统。该系统底层设计采用DSP作为中央处理器,实现对前端采集数据的处理;用CPLD完成整个系统的逻辑控制,简化了系统的硬件设计并提高其稳定性;通过异步通信单元与上位机构成分布式实时监控系统,实现电力参数在线监测、分析。测试表明,该系统能够很好地满足要求。An intelligent three-phase monitoring system is developed for the real-time monitoring of voltage, electric current, frequency, power and other parameters. Adopting the DSP as its CPU in its first floor design, it can process the data collected before hand. Realizing the logic control of the whole system by CPLD, it simplifies the hardware design and upgrades the system stability. Composing the real-time monitoring system by the combination of de-synchoronous communication units and the computer with which they are connected, we realize on-line monitoring and functional analysis of different power parameters. Testing shows that the system can satisfy different monitoring requirements.
