摘要
本文介绍利用PC机RS-232串口实现远程数据采集的方法,主要基于16C554、RS-422接口及RS-232电平转换,利用VisualC++编写数据采集程序,硬件部分主要利用了RS-422接口的长线传输能力及PC机RS-232串口方便性。
This thesis introduces the data communication implementation methods with PC and RS-232. Based on 16C554, RS-422 and RS-232 electrical level translation. Utilize Visual C＋＋ to write the procedure of developing. The hardware adopts RS-422 long distance transmission and RS-232 port of personal computer.
