Research On Warning And Location Of Mobile Phone Client In Landslide Monitoring System

Sudden landslide hazards bring the landslide area residents of the production and life of a serious threat.With the popularity of smart phones,with the rapid development of modern wireless sensor network technology,Internet technology,mobile communication technology and mobile development technology,the establishment of a mass,real-time,fast,interactive,full-featured mobile terminal landslide Monitoring system has become the people's livelihood and social development needs,to protect the lives and property of residents and economic construction is of great significance.In order to establish a landslide monitoring system for the majority of residents,the paper has made in-depth research and application development for mobile client alarm and resident orientation.Firstly,in the mobile client alarm module,the paper analyzes the characteristics of real-time,risk and diversity of landslide data and the portability,timeliness and versatility of smart phones,and designs the model and strategy of landslide monitoring system data alarm.Landslide data characteristic data threshold and set disaster prevention command effect to divide the level of alarm,by listening to SMS,stealing process,interrupted call,audio broadcast,vibration,flash and other ways and means of landslide monitoring area near the residents grading early warning,Using Android mobile phone development platform and application components to achieve mobile phone alarm module function.Landslide residents can access real-time data in real time and are reminded by the powerful warning means on the mobile phone to check the landslide dynamics and take emergency measures.Secondly,a kind of multi-fusion residential localization algorithm is proposed,and the matching algorithm used in WiFi fingerprint positioning technology is proposed.The advantages of the three positioning methods,such as resident positioning module,comprehensive GPS positioning,WiFi positioning and pedestrian flight estimation,Improve,increase the positioning accuracy and speed.Through the GPS outdoor maskless positioning and WiFi indoor networking positioning complement each other,coupled with the use of sensor positioning of theresident path estimation algorithm for the initial position of the correction,to expand the landslide area near the residents to obtain coverage and improve the accuracy of real-time location To facilitate the monitoring system and the government's mastery and management of the location of the population.Finally,the design and development of landslide mobile client data monitoring functions,map functions,database modules and communication modules.Landslide monitoring system mobile phone client alarm function and diversified location of the residents to improve the residents of the landslide monitoring awareness rate,and enhance the residents of the landslide information access timeliness,increased residents to respond to landslide disaster initiative,accurate location of the residents And status information to assist the monitoring system in reducing and preventing the loss of life and property caused by the disaster.
