Research On Key Technologies Of Landslide Early Warning Based On High Precision Measurement

Early warning of landslide geological hazards is a worldwide problem.With the development and maturity of Beidou satellite navigation system in China,related products of Beidou satellite navigation system have been gradually applied and penetrated in all aspects of society and life.The high-precision measurement technology based on Beidou has also been greatly improved,providing new advanced methods for the study of geological disaster monitoring.This paper is based on the relevant research based on Beidou high-precision measurement,combining the advanced technology of Beidou satellite navigation system in China and the relevant frontier technology in the field of Internet of Things and applying it to the early warning of landslides.In this paper,a landslide early warning model is used to determine the stage of evolution of the landslide,so that when the landslide develops to the pre-failure stage,timely warning can be made to reduce the threat to people's lives and property safety when disasters occur.By studying the formation mechanism of landslides and related geology theories,this paper expounds the meaning and elements of landslides,and summarizes the factors of landslides.And by combining the research of high-precision measurement based on Beidou,especially the development of high-precision measurement in the field of deformation monitoring,the overall design of the high-precision measurement platform was carried out.Subsequently,the user,requirements and functional analysis of the platform were completed,and the advanced prototyping method in software engineering practice was used in the requirements development stage of the project.The high-precision measurement platform was prototyped using prototyping tools.This paper also designs the software of the high-precision measurement platform,including analyzing the software architecture of the platform,designing seven functional modules of the high-precision measurement platform in detail,and completing the server-side design of the platform.In terms of data,the platform's data acquisition and database are designed in detail,and the key technology of high-precision measurement data visualization based on the hybrid visualization method is used to visualize the measurement data uploaded by the measurement terminal devices.Based on the work above,this paper sorts out the basic ideas of the landslide warning model based on threshold judgment and the landslide warning model based on process tracking,and puts forward a universal landslide warning model under high-precision measurement conditions.Finally,taking the actual project case application of Niushou Mountain in Nanjing as an example,this paper puts forward an early warning model for early warning of landslides in high-risk areas of the mountain,and determines the evolution stage of landslides in the region through this model,and verifies the feasibility of the early warning model applied to the actual project.The high-precision measurement platform based on the Beidou satellite navigation system designed in this paper can realize the access and management of a variety of Internet of Things terminals and sensor devices.In this paper,through the actual deployment of a high-precision measurement terminal based on Beidou,solving and analyzing the real-time data reported by the terminal,we have successfully studied and designed a landslide warning model.Compared with the traditional method of geological disaster prevention,this study greatly reduces the waste of manpower in disaster early warning,so that relevant scientific researchers can have a basis for judging landslides without being on the scene,and provides new ideas for early warning of landslide disasters.
