基于DSP+CPLD的新型智能监测系统设计与开发

A new system of intelligent monitor design based DSP+CPLD

在对电力系统大型设备智能在线监测中,传统基于单片机的智能仪器系统暴露出系统灵活性不高软硬件通用性不强等诸多弊病。本文以WSM2000DSP智能电动机保护装置项目为背景,提出DSP+CPLD新型智能监测系统的设计方案,它以DSP为底层主处理器,把所有控制电路、地址分配等设计在CPLD中,使整个系统结构简单化,体积小型化,功能多样化,为测控仪器向高层次智能化方向发展提供了充分的现实可行性。

In the intelligent online monitoring of electric power system giant equipment, the traditional intelligent equipment based on SCM（single chip machine）divulge several disadvantages such as insignificant system agility and low software and hardware currency. A new system of intelligent monitor design integrated DSP＋CPLD is put forward about the WSM2000 DSP intelligent electromotor protecting equipment. The DSP is put as its main bottom processor, integrate all command and address distributing circuit in CPLD. The system has a simple structure, mini-cubage and muhi-function. It provides sufficient flexibility for the development of intelligent equipment to the advanced intelligentization.
