Abstract. There exist such problems as high cost, difficult construction and low automation degree of existing landslide monitoring system. To treat these problems, a high-speed railway landslide monitoring system based on Zigbee wireless network technology is designed. In this system, high-speed railway landslide information is obtained by wireless sensor network location technology. Its monitoring data is transmitted by rail side room to remote monitoring center. According to the characteristics of the landslide, location coordinate system is improved. Plan of the system structure and program based on weighted Received Signal Strength Indicator (RSSI) location algorithm is introduced. The simulation experimental results show that the monitoring system can monitor effectively high-speed railway landslide. Keywords: Landslide monitoring Wireless sensor network (WSN) Zigbee Received Signal Strength Indicator (RSSI) Location algorithm
1 Introduction There are many railways that are in complicated geology and frequent scourge mountain areas in China, and the safety of railways is a problem that the operating administration has to face. Through the high-speed railway landslide monitoring, we can know the feature information of the change of landslide mass timely so that we can provide scientific basis to the safe operation of high-speed railway. Up to now, the technologies used to landslide monitoring are mainly include hand gaging [1], GPS positioning system, the disaster sensor detection system [3]. Although the detection technologies that mentioned above can monitor the dynamic information of landslide with efficiency in different ways, there exist such problems as high cost, difficult construction and low automation degree. The WSN based on ZigBee has such advantages as self-organization, low power dissipation, low cost, quicker deploy ability and strong expansibility, which are very appropriate to structure network and set up infrastructure which is used to gather and transmit information in areas that are along the high-speed railway landslide environment.

we can attain the information of the ground movement in the slippery area with efficiency, and response the movement of the surface of the landslide timely, which are very important to the detection of high-speed railway landslide and the safe operation of railway. As an important technology in wireless sensor network, wireless sensor network positioning technology is widely used in landslide detection. According to the need to measure the distance between nodes, we divide the positioning algorithm into distance based and not. Up to now, the distance measuring technology includes RSSI [4], TOA [5], AOA [6], TDOA [7] and so on. And the positioning that don’t need to measure distance
