摘要
M-Bus是一种专门用于公共事业仪表的总线结构。智能水表数据采集器是智能水表远程抄表系统中的重要组成部分。简单地介绍了M-Bus通信协议以及基于M-Bus总线的数据传送工作原理,并根据原理进行了相关的电路设计,具体包括发送电路和接收电路,所设计的两种电路简单实用。采用的控制器是STC系列的双串口单片机STC11F04E,并给出了主程序流程所做的数据采集器具有实时性好,成本低,稳定性高等优点,在具体的应用中有比较好的效果。
M-Bus is a special bus organized structure for meter public utilities.Data acquisition unit of intelligent water meter is an important component of the intelligent water-meter remote reading system.Firstly,the communication protocol and working principle of data transmission based on M-Bus are briefly described,then a related circuit design in accordance with the principle is given.The design includes sending and receiving circuits,which are simple and practical.The controller is dual-port STC11F04E.The main program flow chart is also depicted in the paper.This data collector is of good real-time performance,low-cost,and high stability,and has good effects in the concrete application.
