【摘要】 四川省的地震活动主要发生在西部地区,四川由于地形原因,一旦发生破坏性地震,极易造成震区通信、交通等联系方式的全部中断,形成"信息孤岛"。为了解决"信息孤岛"问题,系统采用智能手机终端与分体式北斗终端链接,通过北斗卫星信道与移动通信网络连通的方式,将人员伤亡和房屋建筑破坏情况等关键灾情信息编码后以短报文形式回传后方指挥部,为地震灾情快速初步判断提供及时、可靠的第一手资料。更多还原

【Abstract】 Seismic activities in Sichuan province occurred mainly in the western Sichuan province. Because of the terrain,once the devastating earthquake occurred,it’s very easy to interrupt all contact ways such as communication and road traffic in earthquake area,forming " information isolated island". To solve the problem of "information isolated island",by using smartphone terminal linked with split-type Beidou terminal,the casualties and building damage and other key disaster information were encoded in short message to transfer back to command,through the connectivity way of the Beidou satellite channel and the mobile communication network. It will provide reliable first-hand information for quick disaster preliminary judgment.更多还原
