基于J2EE的煤层顶板突水预警WebGIS系统设计与实现

介绍了一种基于J2EE规范的煤层顶板突水预警WebGIS系统的设计思想和实现方案,实现互联网上的煤层顶板突水监测预警作业。系统采用了基于J2EE三层架构的设计思想,利用Ajax技术和EJB组件技术实现系统的表现层和业务逻辑层,实现了煤矿井下实时水情数据监测和分析,包括历史数据曲线、实时数据曲线;水情监测数据的存储与检索;先进的地图浏览功能,矿图监测、水质监测;各类矿图信息的地图化管理,方便用户浏览、查询等;应急预警等功能。系统将前端表现和业务逻辑分离,拓宽了传统模式中多用户并发访问和海量空间数据传输的瓶颈。本系统的开发对煤层顶板突水预警系统的研究具有理论意义和工程实用价值。

Design and Practice of WebGIS System Based on J2EE to Alarm Water Inflow into Mine Roof

This paper discussed the design method of WebGIS system based on the J2EE model to alarm water inflow into the mine roof,and the scheme of practices,which can alarm the risk of water inflow into the mine roof on the internet.The WebGIS system utilized the J2EE model and built the presentation and business logic by applying the Ajax and EJB techniques,and can monitor and analyze the real time water data in the underground coal mine,including following functions: the curves of history and real time data,save and search of data,advanced mapping techniques for mining operations and water monitoring,convenient mapping functions for transforming the text information,emergent alarming.The system separates the presentation and business logic,and provides a wider band for concurrent visits of users and the transmission of data.The study of this system has theoretical significance and practical value for alarming the risk of water inflow into the coal mine roof.
