摘要
为了实现电能表读数的远程自动抄表。本文介绍了基于民用CDMA无线网络,采用由WAVECOME公司开发的Q2358C模块而设计的一种新型远程自动抄表系统。该系统由电能表、微控制器、无线收发模块、CDMA网络和计算机等部分组成。无线收发模块是实现信息无线传输的关键部件,通过AT指令与计算机和微控制器通讯,电表数据以短信息方式传输。在详细描述远程自动抄表系统的结构后,研究了短信收发平台及其实现方法。系统具有成本低、实时性好、安全方便等特点。
To transmit the data of the electricity meters remotely and automatically, a new remote automatic metering system for power meter with the module of WAVECOME Q2358C module and the civil CDMA networks is introduced. The system compose of power meter,micro-control unite,CDMA module,CDMA networks and computer etc.The CDMA module is a key device that transmits the signal wirelessly and communicates with PC and micro-control unites through AT command. In this system the data of the electricity meters are transmitted as SMS.After describe the remote Auto-transcription system elaborately, this paper states the SMS-platform and the approach of how to realize the function of the SMS-module.The system has many properties such as low-cost, good real time, safe and convenient.
