无线传感器网络在三峡库区滑坡远程监测中的应用

Application of Wireless Sensor Network in Three Gorges Landslide Remote Monitoring

为解决三峡库区滑坡监测中偏远山区公网信号无法满足远程监测的需求问题,将无线传感器网络引入到三峡库区滑坡远程监测中,并通过国内的北斗卫星通信技术解决偏远山区通信盲区问题,构建了三峡库区滑坡远程监测系统的模型,采用"预警上报,定时传输"的数据传输流程实现滑坡监测数据的传输。实验表明:基于无线传感器网络的监测系统可以满足三峡库区滑坡监测的应用需求;同时,"预警上报,定时传输"的数据传输流程可以有效降低节点能量消耗,延长网络生存周期。

In the landslide monitoring of three gorges reservoir, the public network signal can not meet the demand of remote monitoring. In order to solve the problem, wireless sensor network is introduced to the landslide monitoring system of three gorges reservoir, and it is also helped by beidou satellite commutation system to cover communication blind district, which construct the model of landslide monitoring system of three gorges reservoir. The monitoring data was implemented by the data transmission process of ＇ Alarm Reporting and On-time Transmission＇. Experiments show that the monitoring system, based on the wireless sensor network, can meet its application requirements. At the same time,the data transmission process of ＇Alarm Reporting and On-time Transmission＇ can reduce the energy＂ consumption effectively, and increase network＇ s life.
