摘要
本文论述了在集散型测控系统中，通过PC机串行口实现与多台单片机实时通信的原理、接口电路以及波特率的选择和主从通信程序的协调配合等实现可靠通信的重要措施。
This paper exposed the important measures for implement of reliable communication between IBM PC and 8031 single chip microcomputers by the asynchronous serial adapter, such as the communication ptinciple, the interface the main subordinate communication programs. They are adopted in the concentration distribution system for measurment and control.
