基于C8051F350的带有数据变送器功能的高精度数据采集系统

High Accuracy Data Acquisition System Based on C8051F350 with Transducer

介绍的系统CPU采用C8051F350,利用其24位A/D转换功能,实现了高精度模拟量数据采集,设计的变送电路可以直接测量交直流大电压信号,采用CAN总线协议与计算机进行通信可使数据传送距离达到10 km,有利于遥测功能的实现。

This system adopts C8051 F350 as CPU, and takes advantage of its 24-bit A/D converter to accomplish high accuracy data acquisition. The transducer in the system can measure great DC or AC voltage signal directly. The communication with PC can transmit up to 10 kin, because of used CAN bus,which is conventional to realize remote measure.
