基于北斗卫星通信的地震应急指挥系统研究

An Earthquake Emergency Command System Based on BeiDou Satellite Communication

摘要:

北斗卫星导航系统是我国自主建设、独立运行、具有完全知识产权的卫星导航系统。其兼具定位及通信功能的独有技术优势特别适用于大震后通讯中断的地震应急环境。本研究将北斗卫星通信技术及地理信息技术结合应用于地震应急指挥系统的建设中：基于北斗卫星定位技术解决灾害现场人员的位置追踪；利用北斗短报文技术解决盲区紧急通信问题；采用串口通讯、多线程、SHH2框架、Web GIS等技术构建数据采集、解析及综合呈现平台。最终完成集位置监控、灾情上报、统计展示、指挥调度于一体的北斗应急指挥系统建设，进一步提升了重大地震灾害的应急救助信息保障能力。

Abstract:

The BeiDou navigation satellite system was developed by China and operates independently with full intellectual property rights. With respect to position and communication, it is especially suitable for earthquake emergency environments in which communication is interrupted after a large earthquake. In this study, we constructed an earthquake emergency command system using BeiDou satellite communication technology and geographic information technology. Based on the BeiDou satellite position, the locations of rescue workers at a disaster site can be tracked. BeiDou short message technology is used to ensure emergency communication in blind areas. The platform for data collection, analysis, and comprehensive presentation uses serial communication, multi-threading, an SHH2 framework, Web GIS, and other technologies. Lastly, we constructed a BeiDou emergency command system whose functions include location monitoring, disaster reporting, statistical display, command, and dispatching. The results of this study further improve the ability of the emergency command to acquire information regarding major earthquake disasters.
