文章介绍了一种基于Siemens公司的GSM模块TC45的无线监控系统的设计,系统采用主从式结构,PC作为主控机进行可视控制,显示等操作,单片机用于对数据采集及预处理,PC和单片机通过对GSM Modem(TC45)发送AT指令来实现相互之间的通信。实践证明,利用GSM短信实现远程传输是一种经济、可行的方案。 This paper introduces a design of wireless monitoring system based on Siemens GSM module TC45. The system uses master-slave structure, PC as the main control machine for visual control, display and other operations. The single chip microcomputer is used for data acquisition and preprocessing, PC and SCM through the GSM Modem (TC45) send AT commands to achieve mutual communication. Practice has proved that the use of GSM messaging remote transmission is an economical and feasible solution.
