The characteristics of high-speed railway have wide geographic distribution and complicated natural conditions in China,part of the railways are in conditions of complicated,disaster-prone,climate changeful mountain area,how to ensure the operation security of high-speed railway has become severe,and the transport enterprises must face the issue.However,the existing methods adopted by the landslide monitoring technology have some disadvantages,which are high cost,poor performance,low real-time performance,it seriously affect the monitoring equipment of large scale arrangement and monitoring effect,so research and design a high-speed railway landslide monitoring system based on wireless sensor network(WSN)is extremely urgent.Based on the characteristics of the landslide along high-speed railway,in this paper proposes a landslide monitoring system using Zigbee wireless communications technology and related sensors to real-time monitor the landslide and transmit the information to the remote control center through the rail side room,this system can achieve effectively the remote monitoring of landslide along high-speed railway.In addition,to solve such problems as high cost,difficult construction and low automation degree of the existing landslide monitoring system,a 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 rather than landslide sensors,and proposes based on weighted Received Signal Strength Indicator(RSSI)location algorithm to improve the location accuracy,it can achieve effectively the landslide monitoring and disaster warning.In this paper,the design plan of the system structure,software and hardware based on the environmental characteristics of landslide along high-speed railway are introduced.The main research works in the thesis are as follows:The first chapter introduces the significance of application of WSNs in high-speed railway and the research status of landslide monitoring technology.The second chapter designs the overall structure of high-speed railway landslide monitoring system based on WSN,and introduces the hardware and software design of sensor nodes,routing nodes,gathering node and the remote monitoring center,and the function of each function module is introduced in detail.The feasibility of the system is verified by experiment.The third chapter introduces the research status of wireless sensor network location technology,and the improved based on weighted Received Signal Strength Indicator location algorithm is proposed to improve the location accuracy,the design plan of the system structure,software and hardware based on the location algorithm.The simulation experimental results show that the monitoring system can monitor effectively high-speed railway landslide.The fourth chapter make concludes and prediction about the future work.
