Study of Wireless Sensor Network(WSN) using for slope stability monitoring

摘要

The traditional monitoring equipment cannot satisfy the request of immediate response for slope instability. This study is aim to provide a simple, effective and immediate alarm system to reduce the damage as much as possible by real time before disasters happens, and take reaction at once. The advanced, high technology of Wireless Sensor Network (WSN) is firstly introduced for this application in Taiwan. MEMS tilt meter, sensitivity with 0.5 degree in X Y direction is used for monitoring the changes from features of slope stability IEEE standard of ZigBee is applied for wireless communication network. Since this intelligent WSN system contains sensors, wireless transmission, and low power supply, each single node becomes a data collection and transmission base. This study, a trial program has significant results show that for any movement from the slope surface, the sensor data can pass through all the nodes. And to reach the server station, then the reaction from management office can be taken at once.
