基于GPRS/GMS管道燃气泄漏监控系统的设计

Design Based on GPRS/GMS Pipeline Gas Leaking Monitoring System

针对目前燃气泄漏检测中存在的问题,设计了一种基于GPRS/GSM混合通讯的管道燃气泄漏检测装置及报警系统,重点介绍了监控终端的结构和原理,以及通信软件的设计流程。采用ARM7CPU控制GPRSmoder接入Inter-net,实现无线数据传输,数据传输以GPRS为主,辅之以GSM,采用气压与气敏两种传感器进行检漏,提高了系统的可靠性和实时性,这对管道燃气的推广使用有一定现实意义。

In connection with the problems in gas leaking test at present, the paper designs a kind of pipeline gas leaking testing device and alarmreporting system based on GPRS/GSM mixed communication and mainly introduces the structure and principle of the control terminal and the design procedure of the communications software. It uses ARMTCPU to control GPRSmoder connecting with Intemet to realize wireless data transfer. The data transfer has mainly focused on GPRS and makes only a little attention to GSM. It uses two kinds of examining leaking methods including atmospheric pressure and gas sensing to improve the reliability and real - time pefformanee of the system, which has some practical significance to the extension of the pipeline gas.
