集中抄表系统中的握手联络式串行通信协议

Handshaking serial communication protocol of centralized meter reading system

介绍了集中抄表系统中的握手联络方式的PC机与多单片机的串行通信设计方法,具有通信可靠性高的特点。并可应用于下位机并非一直处于接收就绪状态的场合,如实时控制、实时信号处理应用中。最后给出了通信协议及PDL语言的程序设计流程。

In this paper,a handshaking serial communication protocol between PC and multi MCU is introduced. It is applied to some occasions,such as real time control and signal processing with high reliability.The communication protocol and program flow of PDL are also given.
