基于微处理器的经济型数据采集平台设计

Design of Economic Data Acquisition Platform based on the DSP Microprocessor

本文研制了一种低成本基于微处理器的经济型数据采集平台。完成了总体方案设计与数据采集平台各部分的硬件设计工作,对系统DSP最小系统,AD转换电路、以及系统显控和上位机通讯电路三部份进行了详细的设计,开发设计了基于微处理器的经济型数据采集平台的监控软件,包括AD采样软件、键盘接口显示软件、以及串行口通讯软件。最后,对采集到的信号进行了数字滤波预处理。

In this paper,a low cost,economic data acquisition system based on the DSP microprocessor is developed.It designs the frame structure and the hardware of the data acquisition platform,especially design the basic DSP system,A/D transfer circuit,the DCI driver and the communication circuit with the computer in detail.Then,that monitoring and control software of the economic data acquisition platform based on the DSP microprocessor,including A/D sampling,Keyboard interface,and serial port communicationsoftware...
