    摘要:

    由于現有系統受聚集路線(xiàn)延遲影響,導致地震應急信息質(zhì)量控制效果不明顯,為了解決這個(gè)問(wèn)題,設計了基于遙感GIS的地震應急信息質(zhì)量控制系統。設計遙感GIS的地震應急信息總體架構,通過(guò)地震應急信息管理模塊控制屬性信息庫進(jìn)行空間控制。硬件部分設計帶有物理超分辨率顯示模塊的存儲服務(wù)器,通過(guò)用戶(hù)交互界面建立網(wǎng)絡(luò )消息驅動(dòng)的顯示程序,并與用戶(hù)直接交互。設計帶有秒啟動(dòng)環(huán)網(wǎng)功能的WEB服務(wù)器,避免系統出現故障停機情況。采用主從式方式,以GIS平臺為支撐,設計全景操作端,顯示GIS程序屏幕地震應急信息。考慮地震應急信息傳輸通道沖突概率,將多路地震應急信息聚集結果有效返回到Sink上,根據基于同心圓并行路線(xiàn),避免額外增加應急信息傳輸通道量,計算聚集路線(xiàn)延遲。通過(guò)同心圓并行路線(xiàn)維護聚集地震應急信息表,并設計信息聚焦控制實(shí)現步驟,完成軟件部分的設計。由實(shí)驗結果可知,該算法在60s聚集時(shí)間內,地震應急信息傳輸量為6.2G,這些地震應急信息全是可觀(guān)測信息,具有明顯地震應急信息質(zhì)量控制效果。

    Abstract:

    Because the existing system is affected by the delay of gathering route, the quality control effect of earthquake emergency information is not obvious. In order to solve this problem, a quality control system of earthquake emergency information based on remote sensing GIS is designed. The overall framework of earthquake emergency information of remote sensing GIS is designed, and the attribute information database is controlled by the earthquake emergency information management module for spatial control. In the hardware part, a storage server with physical super-resolution display module is designed, and a network message driven display program is established through the user interface, which can interact with the user directly. Design a web server with the function of starting ring network in seconds to avoid system failure and shutdown. Using the master-slave mode, supported by the GIS platform, the panoramic operation terminal is designed to display the earthquake emergency information on the GIS program screen. Considering the collision probability of earthquake emergency information transmission channel, the multi-channel earthquake emergency information aggregation results are effectively returned to sink. According to the concentric circle based parallel route, the additional amount of emergency information transmission channel is avoided, and the aggregation route delay is calculated. Through the concentric circle parallel route, the earthquake emergency information table is maintained, and the information focus control implementation steps are designed to complete the software design. The experimental results show that the transmission amount of earthquake emergency information is 6.2g in 60s aggregation time, and all the earthquake emergency information is observable information, which has obvious effect of earthquake emergency information quality control.
