Soil Moisture Collection Of Wireless Sensor Use For Landslide Prediction

A number of expert researches indicate that soil humidity is the key factor that causes landslide. Therefore, it’s necessary to monitor the soil on the slope in order to reduce the damage and loss of landslide which means the method study of collection of soil humidity has a practical significance.This paper firstly studies the mechanism and characteristics of landslide occurrence,then discusses the change and impact of soil humidity resulting from the change of rainfall and groundwater mass. All these not only confirm certain required principal elements of landslide monitoring but also provide the vital basis for humidity collection.The emphasis of this thesis is soil humidity collection in the method research of landslide monitoring. The project would be achieved by the support of the hardware of Zig Bee sensing nodes, node writing, data storage and the monitoring interface of upper computer.CC2530 is adopted as a node processor to establish Zig Bee network. The node consists of host node and deputy node for its each different use. In other word, they conduct their respective relevant periphery circuit design and node writing by using IAR software. Host node plays a part in the wireless network construction and data transmission of upper computer while the deputy one deals with the data acquisition with the help of the humidity sensor.Serial port can be read, data can be saved and some other this kind of complex operations can be finished only by simple programs since Labview software is selected to design the interface of the upper computer. In addition, cheer and bright interface come into being because of Labview.There are plenty of related distinct and intact charts which have good reference value to landslide monitoring such as structure charts, flow charts, circuit design charts, program codes of the master and vice nodes.
