备注

通过建立云南省IP地址定位与状态变化数据基础数据库,使用互联网信报控制协议,研发基于互联网信报控制协议的灾情信息收集系统,实现对云南省IP地址主机设备震前、震后的在线状态比对,短时间内生成震区灾情判断数据,为震害评估及应急决策提供依据。经过2017年云南2次地震检验,该系统收集数据及分析结果满足地震应急相关工作需求。

In this paper,we firstly built a foundation database of the IP address information of on-line equipments and their dynamic state,then taking the advantage of Internet Message Control Protocol(IMCP),we developed a system for disaster-information acquisition,which was capable of comparing the state of the on-line equipments before and after an earthquake,and outputting the estimated situations in the earthquake-stricken area,to help the emergency personnel to assess the losses and make decisions. The system was applied into the emergency work for the magnitude 4.9 earthquake occured on 8th,Feb. and magnitude 4.5 earthquake on 12th,Mar.,2017,which was proved to be practicable.
