基于DSP的远程数据采集系统设计

Design of Remote Data Acquisition System Based on DSP

多路数据远程采集系统在工业现场中用得越来越多。本文结合TMS320LF2407的自身优势,详细介绍了如何利用DSP自带的10位16通道的AD转换器和CAN总线控制器实现多路数据的远程采集,提供了系统实用的原理图和源代码,给出了系统信号调理和数据处理的方法。此系统结构简单,经济实用。

Nowadays more and more multi-channels＇data remote acquisition systems are applied in industry spots.With advantage of DSP（TMS320LF2407） itself,realization of remote dada acquisition with 16 channels utilizing 10-bit AD conversion and CANbus controller based on DSP（TMS320LF2407） is introduced in detail in this paper.Not only both hardware and software are discussed in detail,but also the schematic diagram and source code applied are offered,and signal adjusting and data processing are introduced as well.The system has low cost,simple structure and good practicality.
