摘要
本文介绍了用红外线实现上位单片机和多个单片机间的无线串行通信的新方法,并基于该方法设计实现了新型无线抄表系统,给出了硬件线路图、通信协议和程序流程图及用MCS51汇编语言编写的部分串行通信程序。
This paper describes a new method to realize the master slave mode communication through serial ports between master microchip and other microchips by using infrared .Base on the method a new wireless meter reading system was proposed. Circuit , protocol ,flow chart and part source codes of MCS51 are also presented for serial communicating,
