Study On Information Control And System Development Of Roller Compaction Process Of Rock Fill Dam Based On WebGIS

With the continuous improvement of rock fill dam construction management,more and more projects begin to use information technology to improve the dam construction process.Visual monitoring platform of roller compaction quality for rock fill dam is widely used in large-scale rock fill dam construction management for its comprehensive data and rich display effect.The traditional rolling monitoring platform adopts C/S asynchronous,which cannot realize the quick view and sharing of the rolling status on the network.In response to solve this problem,this paper will use B/S asynchronous to build monitoring platform of roller compaction quality.The web server,node.j s server and database server are built in this paper to realize the information management and visual display,combining Cesium,Bootstrap and ThinkPHP frameworks with iot technology and WebSocket technology.This research mainly involves the followings:(1)WebGIS Platform:Visual monitoring platform of roller compaction quality for rock fill dam is built by Cesium open-source framework.Three-dimensional effect display of terrain data,model information,rolling monitoring information and historical data can be realized through data processing and interface interchange,which provide effective monitoring and management for manager.(2)Real-time transmission for Web data:Using WebSocket technology,real-time data transfer from server to client is achieved by node.js server and socket.io framework.In order to call data conveniently for Visual monitoring platform,data supported by Cesium is processed real-timely through this server.(3)Hardware platform construction and monitoring management mode:According to the rolling standard developed by rolling compaction experiment based on relevant specifications,a set of construction management mode suitable for rolling monitoring platform is designed,which can publish non-standard construction information timely and accurately.By means of real-time positioning technology and information query function,non-standard construction can be identified and processed timely by manager to ensure the quality of rolling compaction and improve construction management.(4)System development:Combining with the relevant construction regulations of engineering information management platform,this article designed the system architecture and function framework and developed the WebGIS-based Visual monitoring and information management platform of roller compaction quality for rock fill dam.
