Research And Design Of Intelligent Monitoring System For Landslide

There are tens of thousands of landslides and other geological disasters of different scale in our country every year,causing huge losses to the natural environment,infrastructure building,even endanger people's lives and property safety,resulting in casualties.According to the relevant department statistics,every year due to landslides,landslides,landslides and other disasters caused by the annual economic losses of up to several billion yuan.Timely monitoring of landslide area,to master the trend of landslide change,to establish a reasonable and stable prediction and early warning system,which can minimize the losses caused by landslide disaster and protect the safety of people's lives and property.With the development of recent years,a variety of new landslide monitoring technology began to appear and applied to the actual,and gradually replace the past manual field monitoring methods.The overall goal of the new technology to achieve the goal is to achieve real-time monitoring of the process,remote,accurate.Under these background,this paper analyzes and studies the technology of landslide monitoring,and designs a kind of landslide monitoring system based on MMA8451 three axis speed sensor.The whole system with wireless transmission function,in the indoor PC can be measured to real-time image and landslide displacement parameters and other information,grasp the moving condition of the landslide,when to set warning threshold value,the system will alarm,so as to timely disaster prevention work.In this paper,we first study the factors that affect the landslide,classify the landslide according to different factors,and then give different methods to calculate the stability of the main accumulation layer(including soil)landslide and rock landslide.And give the early warning indicators,to facilitate the further completion of the system design.Secondly,the design of the system hardware circuit is completed,the design requirements of the analysis system,the selection of key components according to the actual demand,the circuit design of the main function modules,etc..Then is the system software programming,introduced the software design overall frame and the process,the data collection process,the data processing key step method as well as the human computer interaction interface design.At last,the testing and debugging of the monitoring system performance index are proved,and the reliability and accuracy of the system are verified.The whole block diagram,hardware module and software system of the landslide monitoring system are given in detail.The system can run stably in the laboratory environment and can achieve high detection accuracy.The problems such as high cost,long monitoring period,inconvenient operation and poor real-time dynamic performance are solved.
