摘要
针对智能低功耗直读水表为主的集中抄表系统,设计一种基于STC12C1052单片机控制的分立元件M-BUS适配器,完成对连接到M-BUS总线上智能表数据的收发并通过集中器上传到监控计算机,从而实现远程抄表。介绍M-BUS总线及适配器的工作原理,详细阐述在单片机控制下的M-BUS总线信号收发电路,过流及短路保护,故障检测及故障信号发送,远程唤醒及其在远程抄表中的应用。由于采用分立元件设计,不受知识产权限制,大大增加了M-BUS接收电路的运用。
Aiming at the centralized meter reading system based on intelligent low-power direct reading water meter,a discrete component M-BUS adapter based on STC12C1052 microcontroller is designed to complete the data sending and receiving of the intelligent meter connected to M-BUS and upload the data to the monitoring computer through the concentrator,so as to realize remote meter reading.This paper introduces the working principle of the M-BUS and the adaptor,and expounds in detail the M-BUS signal transceiver circuit,over current and short circuit protection,fault detection and fault signal transmission,remote wake-up and its application in remote meter reading.As the discrete components design is not limited by intellectual property rights,the circuit designed greatly increased the use of M-BUS receiving circuit.
