可自定义的无线远程监控终端的原理与设计

本文介绍了一种基于GSM（全球移动通信系统）网络SMS（短信业务）的无线远程监控终端的原理及设计实现。它由一个无线GSM模块（Siemens公司的TC35T模块）和一个以单片机（AT89S52）为核心的监控单元组成，监控单元利用AT指令通过串口和GSM模块进行交互。它借助GSM模块TC35T，使用户能够通过手机中文短信便捷地对相关设备进行监控。它具有让用户根据具体的监控对象进行自定义的功能，使用户的操作变得更加直观、方便。

The Principle and Design of Wireless Remote Monitor and Control Terminal Self-defined

This paper introduces the principle and design of a wireless remote mo nitor and control terminal base on SMS of GSM. The terminal consists of a wirele ss GSM module (TC35T module produced by Siemens company) and a monitoring and co ntrol unit taking single-chip microcomputer (AT89S52) as the core. Using the AT commands,the monitoring and control unit can communicate with the GSM module th ough serial interface. The terminal let people monitor and control the equipment s easily and conveniently by Chinese short message of mobile phone,using GSM mo dule TC35T. It has the function that people can self-define the terminal accordi ng to idiographic object monitored and controlled,and makes the operation of pe ople more intuitive and convenient.
