基于GSM短信技术的大坝安全监测系统设计

A Dam Safety Monitoring System Based on GSM SMS Technology

有线介质传输网络存在架设及运营费用高、可扩展性差等问题,制约了大坝安全监测系统的推广与应用。设计一种基于GSM短信技术的大坝安全监测系统,主要由无线传感器网络、GSM短信中心和监测中心3部分组成,利用多线程技术,实现监测中心与网关之间实时双向短信通信。试验表明:该监测系统传输时延小,传输质量稳定可靠。

This paper presents a new dam safety monitoring system using GSM industrial module. The monitoring system consists of three major components such as wireless sensor networks, GSM SMS center and monitoring centers. In the case of simulating wireless sensor network gateway in commercial handsets, using multi-threading technology,the monitoring system can successfully implement a real-time two-way SMS communication between the monitoring center and gateways. The experiments show that the transmission delay of the monitoring system is small, and the transmission quality is stable and reliable. This new program solves well the wired media transmission network problems of wiring and rebuilding, lines easily damaged and so on.
