摘　　要：针对当前城市事故频发,城市道路错综复杂,救援实时调度性差等问题,采用A-GPS定位技术,设计实现一种基于移动终端的搜救人员实时定位调度系统。其工作原理是在卫星,基站和A-GPS服务器的协同处理下确定搜救人员与灾害发生地两点位置,再结合地图匹配算法获取两点之间多条通道,为城市灾害救援过程提供科学依据。经测试,在模拟救援过程中,系统具有定位误差低,调度通信迅速,匹配路段效率高等特点。Provides the problems of the current city disaster situation, the perplexing city roads, the worse real-time dispatching of disaster rescue, uses the A-GPS positioning technology, designs and realizes a real-time positioning and dispatching system for rescuer based on the mo- bile terminal. The working principle of the system is that the satellites, base stations and the A-GPS server confirm the positioning of res- cuer and disaster place coordinated , and then combines with map matching algorithm to obtain a plurality of channels between two points, provides the scientific basis for the city disaster rescuing process. The test result shows that the system has low localization errors, high dispatching and communication speedily, effective matching optimization route at the simulation of the rescue process.
