在铁路事故救援过程中,能快速了解事故发生地的地形、地貌、天气、线桥情况,对路局领导指挥事故救援工作提供了极大的帮助,在没有赶到现场时就能对事发地了如指掌,尽快作出救援方案,节约了时间,使损失减到最小,这是开发地理信息查询系统意义所在。 地理信息查询系统包含了铁路沿线的视频资料和与其一一对应的工务信息,可以查询相关位置的录像和工务信息,同样还能从曲线、桥梁的资料定位到相应的录像。能查询领导所关心的站场图资料,具有放大、缩小、打印的功能。该系统利用数据库技术、多媒体技术、网络技术来完成各项功能,以文字、图片、录像、照片四种信息模式表现,检索方便,实用性强。系统开发采用SQLServer数据库和Visual Basic编程工
In the course of the railway accident rescue, it can quickly understand the terrain, landform, weather and bridge situation where the accident happened, and it is very helpful to the rescue work of the command and command leading by the railway bureau. When the accident happened, Well aware of the rescue plan as soon as possible to save time and minimize the loss, which is the development of geographical information query system where. Geographic information system includes the video along the railway line and its corresponding one of the public works information, you can query the relevant location of video and public information, but also from the curve, the bridge data to locate the corresponding video. Can check the leadership of the station map data, with zoom in, zoom out, print function. The system uses the database technology, multimedia technology, network technology to complete the various functions, text, pictures, videos, photos, four kinds of information mode performance, retrieval convenience, practicality. System development using SQLServer database and Visual Basic programming
