Design of Subsidence Monitoring System Based on Wireless Sensor Networks

In view of tradition monitoring method for land subsidence existence insufficiency, such as wiring is difficulty and work load is big, and so on. It proposed a new long-distance monitoring method for land subsidence based on the wireless sensor networking (WSN) so as to solve the difficult problem, which the GPS(Global Position System) technology and the InSAR(Interferometer Synthetic Aperture Radar) technology are difficulty to gain various strata micro-deformation characteristic. The micro-data of stratum were wireless long-distance gathered and transmitted by using ZigBee & the GPRS wireless communication technology. It introduced the monitor principle for land subsidence, and discussed hardware architecture and the software realization of Three Gorges Reservoir Region land subsidence observation system based on the ZigBee wireless sensor network. Finally, it introduced with emphasis the observation system terminal node and the wireless gateway node part´s software programming realizes.
