Design And Implementation Of Remote Monitoring System For Rockburst Based On WebGIS

As the exploitation of coal resources is deeper and deeper,the impact of rock pressure is becoming more frequent,and real-time scientific monitoring of rock pressure is crucial.With the development of geographic information system(GIS)technology,it provides an advanced method for remote online monitoring and early warning of rock pressure.With the advent of the Internet era,the Web has become a new world of GIS theory and technology,which can be better on this platform.The use of GIS means to solve various problems in real production.In recent years,WebGIS technology has been applied more and more in the field of coal mines.Based on the national special project sub-project--multi-parameter comprehensive early warning platform for impact mine pressure remote monitoring,this paper studies the open source GIS development framework and spatial analysis based on GIS.Etc.,completed the development of the remote monitoring platform for impact rock pressure.The main research work is as follows(1)The development framework and key technologies of the rock pressure remote monitoring platform were studied.Researched the current mainstream open source GIS framework;based on the business needs,OpenLayers+Geoserver’s open source WebGIS solution;after analyzing the major mainstream integration platforms and development technologies,select the.NET-based MVC three-tier architecture development system,using JQuery Library,Highcharts library,asp.net,etc.,use sqlserver database to store and manage mine pressure monitoring data.(2)Spatial analysis based on GIS to solve the space warning model of the impact rock pressure monitoring system.The heatmap analysis is used to solve the visual expression of the focal point aggregation in the mining area;Spatial autocorrelation analysis based on geographic location of seismic pressure monitoring data;The spatial interpolation method of mine pressure monitoring data is studied,and the formula derivation of Kriging interpolation algorithm is carried out.Comparing the two types of interpolation methods,it is concluded that the local ordinary Kriging interpolation has the highest precision.(3)The system is developed.The whole system consists of three parts: basic function module,business function module and system management function module.The basic function module realizes the basic operations of the map and the functionsof data display;The business function module realizes the core function of the impact mine pressure monitoring and early warning;the system management module realizes the user’s hierarchical management and authority setting.
