基于LPC2214的电参数采集系统

Design of Electrical Parameter Acquisition System Based on LPC2214

为掌控电力系统的运行情况,必须实时准确地采集系统的各项电参数。设计了一种新型电参数采集系统,以ARM7处理器LPC2214为核心并结合高精度16位芯片AD7656来实现。给出了二者的接口,同时描述了系统硬件部分的存储器扩展模块、显示模块及通讯模块的结构。移植了嵌入式实时操作系统μc/OS-II来管理不同的任务模块,提高了系统的实时性及可靠性。该系统有良好的实用性,可用于诸多需要实时高精度监测电压或电流的领域。

To monitor the working status of power system,the electrical parameters must be sampled precisely at real time.A novel design of electrical parameters acquisition system was presented,using LPC2214 ARM7 and high precise 16-bit AD7656.The interface between them was designed.Meanwhile,the structure of system that included the memory expending part,the display part and the communication part was introduced.The embedded real-time operating system μc/OS-II was transplanted to manage various task modules,which im...
