基于Unity3D的微震监测分析虚拟现实系统研发
|
摘要
微震监测对矿山安全生产具有重要意义,也得到了广泛应用。针对微震监测数据数量庞大、内容冗杂、实时显示弱、与采掘工程集成度低等问题,开发了一种基于Unity3D平台的微震监测数据分析平台。其主要过程是:收集矿山三维地质坐标、地层岩性等数据建立矿山三维模型,导入到Unity3D引擎当中,对模型添加材质,进行渲染并实现模型坐标数据与现实坐标数据整合,在此基础上利用C#语言编写脚本实现采掘进度的实时模拟,再通过连接SQL Server数据库将矿井微震监测数据进行调用,完成整个系统地质数据、采掘数据与微震数据的集成和实时显示。通过调用系统数据,可实现微震数据的相关统计、分析,并分析其与地质条件、采掘活动的相关性。系统在河南义马煤田跃进、常村两矿进行了实际应用,实现了矿井群开采微震监测数据的联合分析。
Microseismic monitoring is of great significance to mine safety and has been widely used. In view of the problems of large amount of microseismic monitoring data,redundant content,weak real-time display and low integration with mining engineering,a microseismic monitoring data analysis platform based on Unity3D platform was developed. The main process is as follows: 3D geological coordinates of the mine,the lithology of the formation and other datas are collected to build a 3D model of the mine,then they are imported into the Unity3D engine. After that,materials are added to the model,and the model coordinate data with the real coordinate data are rendered and integrated.Based on this,C# language scripting is employed torealize the real-time simulation of mining progress,and then calls the SQL Server data base to call the mine microseismic monitoring data to complete the integration and real-time display of the whole system geological data,mining data and microseismic data. By calling the system data,the relevant statistics and analysis of the microseismic data can be realized,and the correlation with the geological conditions and mining activities can be analyzed. The system has been applied in Yuejin and Changcun mines of Yima coalfield,and the joint analysis of microseismic monitoring data of mine-group mining has been realized.
