基于DSP和CAN的现场总线数据采集系统

A field-bus data acquisition system based on DSP and CAN

针对传统的数据采集不能满足工业管道系统和楼宇自动化系统中采集量过多,信号复杂分散的问题,提出了基于DSP和CAN总线构成的现场数据采集存储系统的基本结构。介绍了利用DSP芯片TM320LF2407A实现下位的数据采集存储器的实现。同时重点给出了与DSP所带CAN控制器配合的接口的硬件电路和通讯软件的设计框架。

Aiming at the traditional data acquisition system which can not stand the huge number dispersed complex signals used in the oil pipeline system and the Building automation system, a field-bus data acquisition system based DSP and CAN Bus was put forward. TMS320LF2407A are applied to the underlayer data acquisition and store system. The hardware circuit of the CAN interface and the communication software structure is emphasized.
