Design of Landslide Warning System

In recent years, the frequent occurrence of landslide disasters, caused great harm to people´s lives and properties. This paper designs some wireless sensor monitoring nodes distributed on the hillside, they construct a wireless data collection network based on the ZigBee protocol. This design combines GSM wireless communication technology and wireless sensor network, it have completed the work from the system solution to the whole process of software and hardware design. The result proves that each node works stably and the status of network communication is good. This design can collects the depth of water in the mountain and the slope angle of the hillside, and provides the monitoring center with warning information in time, so related departments can take effective measures rapidly to protect people´s lives and properties.
