摘要
介绍AD7891和DSP结合的车辆称重采集系统的设计方案,选用AD7891实现多路数据的高速采集,根据AD7891的工作时序图,采用TMS320LF2407实现时序控制,介绍系统软件和硬件设计。结果表明该系统设计满足要求,且硬件电路易于实现。
The design of vehicle weighing system which is combined with AD7891 and DSP is introduced in the paper. AD7891 is adopted to realize multi-channel data acquisition.Based on AD7891 timing sequence,the timing sequence control is realized through I/O ports of DSP TMS320LF2407.The design of hardware and software are introduced.The result shows the design can satisfy the system requirement, and the hardware circuit is simple.
