The Design Of Mountain Landslide Real-Time Monitoring System Based On Wireless Sensor Network

This system unifies the wireless sensor network technology and the GPS localization technology and the GSM wireless communication technology, according to the needs of the landslide monitoring techniques. The design completes the landslide region real-time monitoring.According to the shape of mountain, the design proposes a new topology frame of wireless sensor network, which is named "Grade and Sequence Faveolate Topology frame". This topology overcomes the shortcoming of star model and reticulation structure. The design realizes the network communication process of collection data from sensor node to sink node using the mode of multi-jump-router.In hardware aspect, the print curcuit board design of the sensor node, the sink node and their emulator are implemented. The sensor node is composed of MSP430F169 and CC1100. The sink node is composed of S3C44B0X, GPS module and GSM module. The print circuit board of sensor node and sink node provides physical realization for the whole design.In software aspect, the software design of sensor node and sink node is the main task. The sensor node takes IAR as sonftware development platform. The topic design the application of every model.The topic designes wireless sensor network's topology frame, and ensure the reliability of data acquisition and transmission. In the paper BootLoader is designed for the sink node. The real time operation system, which is namedμC/OS-Ⅱhas been transplanted successfully into the ARM process on the sink node board. Meanwhile, the task schedule has been set up according to the system structure. The module driver is designed on the basis ofμC/OS-Ⅱoperating system. The data is integrated, such as RF received information, GPS orientation information, collection time, and so on. The data is transmited through the SMS. Remote terminal is auxiliary to display the data. It provides no graphical interfaces.Following standard development process, the debugging of the mountain landslide real-time monitoring system based on wireless sensor network is successed. Using this system, landslide is real-time monitored. This new method supplies a gap of the traditional monitor methods. Good results have achieved.
