近几年来，全球通信技术的发展日新月异，尤其是无线通信技术的发展速度与应用领域已经超过了固定通信技术，呈现出如火如荼的发展态势。它具有无需架设传输线、网络部署迅速便捷、运行可靠和调试简单等优点。其中最具代表性的蜂窝移动通信技术，使人们可以随时随地实现语音通信、短信息传输等。但对于中短距离的自动化数据采集系统、计算机遥测遥控系统、车辆监控系统、小区智能管理和矿工定位等领域，移动通信系统的安装、运行成本是比较高的，因此笔者给出了一种低成本、具有短信息和语音传输功能的无线监控系统设计方案-In recent years, global communications technology is advancing rapidly, In particular, wireless communications technology development and application rate has exceeded the fixed communications technologies, showing the development trend in full swing. It is not set up transmission lines, the network quickly and easily deployed, reliable and simple debugging advantages. One of the most representative of the cellular mobile communication technology, it makes people realize voice communication anywhere, short message transmission. But for short distance from the automated data collection system, the computer remote monitoring and control systems, vehicle monitoring system, Intelligent Management Area miners and positioning, and other fields, mobile communication system for the installation, o
