【摘要】 破坏性地震发生后,快速的地震灾情获取是地震应急救援工作的重要环节。借助"三网一员"体系,利用移动终端技术、无线通信技术、GIS技术、GPS技术等建成了基于个人数码助理(Personal Digital Assistant)的四川灾情速报系统。介绍了系统的结构框架、技术路线和主要功能,并就其中涉及的灾情分类编码、离线地图设计等关键技术进行了探讨。在4.20芦山7.0级强烈地震中,系统实现了震后2 h内的灾情的快速上报,有效缩短了"灾情黑箱期"。更多还原

【Abstract】 After the destructive earthquakes,the rapid acquisition of earthquake disaster information is very important for earthquake emergency and rescue work. With the help of "three nets and one person" system,by using the mobile terminal technology,wireless communication technology,GIS technology,GPS technology,the paper builds the Sichuan earthquake disaster rapid reporting system based on PDA. This paper introduces in detail the structure,technical route and main functions,and discusses the key technology of hazard information classification and offline map. The system achieves a rapid reporting within two hours after the earthquake,and effectively shortens the "disaster information black-box" stage in the 4.20 Lushan strong earthquake. It provides some experience and demonstration for the construction of similar systems.更多还原
