基于FPGA和MC35I的远程数据采集系统

数据采集系统一般采用CPU控制，有线传输，成本较高，监控距离受限，故很难达到多路数据采集的实时性，因此考虑采用硬件直接控制，实现实时数据采集，并充分利用现有的网络通信资源，达到成本较低的无线远程监控目的。提出了采用由FPGA（现场可编程门阵列）控制多路A／D转换和数据存储，并采用GPRS（通用分组无线电业务）网络数据传送方式的设计方案，介绍了其硬件组成和信号流程，阐述了主要软件模块的实现过程。目前该系统已应用于某污水处理系统。

The Remote Data Collect System Based on FPGA and MC35I

The data collection and wired transmission usually are controlled through CPU,therefore it is difficult to achieve timeliness Multi-channel data collection.And monitoring distance will be limited,as well as cost is high,so it could be advantageous to considere that the data collection control is carried out directly by hardware,and to make full use of network and communications resource,to realize the remote wireless monitoring at low cost.A design plan is proposed in this paper that the A/D Conversion and ...
