摘要
本文介绍了一种由ＰＣ２８６和多台单片机构成的分布式数据采集系统。本系统能有效地抑制共模噪声，具有较高的传输速率、传输距离和可靠性，解决了ＣＰＵ速度快而串口速度慢的矛盾。
A distributed data acquisition system composed of PC 286 and several 8098 single chip computers is introduced in this paper This system is able to decrease effectively common mode noise and is of relatively high transmission speed long transmission distance and reliability This system solves the problem between the high speed of CPU and low speed of serial communication interface.
