Design of earthquake emergency information quality control system based on remote sensing GIS

摘要:

由于现有系统受聚集路线延迟影响，导致地震应急信息质量控制效果不明显，为了解决这个问题，设计了基于遥感GIS的地震应急信息质量控制系统。设计遥感GIS的地震应急信息总体架构，通过地震应急信息管理模块控制属性信息库进行空间控制。硬件部分设计带有物理超分辨率显示模块的存储服务器，通过用户交互界面建立网络消息驱动的显示程序，并与用户直接交互。设计带有秒启动环网功能的WEB服务器，避免系统出现故障停机情况。采用主从式方式，以GIS平台为支撑，设计全景操作端，显示GIS程序屏幕地震应急信息。考虑地震应急信息传输通道冲突概率，将多路地震应急信息聚集结果有效返回到Sink上，根据基于同心圆并行路线，避免额外增加应急信息传输通道量，计算聚集路线延迟。通过同心圆并行路线维护聚集地震应急信息表，并设计信息聚焦控制实现步骤，完成软件部分的设计。由实验结果可知，该算法在60s聚集时间内，地震应急信息传输量为6.2G，这些地震应急信息全是可观测信息，具有明显地震应急信息质量控制效果。

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.
