基于GPRS的热电远程监控系统开发应用

GPRS是在GSM体制上发展起来的新型无线分组数据业务，具有实时在线、按量计费、快捷登陆、高速传输、自如切换、资源共享和丰富带宽等优点。文中针对供热管网人工计量以及电台传输监控系统存在的问题，通过对比论证，利用中国移动通信GPRS数据传输网络平台，开发GPRS数据传输终端，设计编制了切实可行的通信协议和具有本项目特点的硬、软件，利用SIM卡绑定固定IP地址，建立了东方热电虚拟专用网，成功地实现了供热管网远程数据采集监控系统，并分析了这种体制的可行性、经济性和优越性。

The development and application of remote thermoelectric monitoring system based on GPRS

GPRS is a new type of wireless data packets technique,which is developed on the GSM system,and it has some advantages such as real-time on line,charging based on consumption,quickly landing,transmitting at high speed,switching freely,resource-sharing,abundant bandwidth. Through analyzing the problems,which existed in the manual measuring system of heating pipe network and the monitoring system of radio transmission,the thermoelectric virtual private network of Eastern Group is set up. We have developed the GPRS data transmission terminal and the feasible communication protocols,and designed suitable hardware and software system for this network. By utilizing SIM card provided by China Mobile GPRS,the regular IP address is tied,remote data transmission of heating pipe network monitoring system is successfully realized. The feasibility,economics and superiority of this network are analyzed too.
