【摘要】 针对边疆公共安全与应急反应应用需求与具体特点,基于北斗终端、GPS终冬端、智能PDA、北斗卫星通信网络和移动通信网络,构建移动应急位置服务网,实现基于北斗的移动应急监控与指挥技术。以车载型北斗终端作为服务中心接入模块(代替指挥型北斗用户机),接入其它北斗应用终端上报的位置与信息,以降低北斗的应用组网成本。基于通信服务器研发北斗终端与GPS终端的位置与信息融合与交互技术,实现应急反应友邻互视、信息交互、移动指挥等功能,实现移动通信覆盖盲区(沙漠、戈壁、边境等)的人员、车辆、物资监控与指挥。在应急位置服务网中,PDA可与北斗终端进行通信;基于移动GIS可对北斗终端及其它GPS终端进行位置监控和指挥,从而为应急管理中存在的现场位置共享、团队协作和移动指挥等问题提供可行解决方案。结合新疆兵团某师开展了技术验证与示范,试运行表明,系统与技术可满足边境应急反应的基本需求,并具有较好的灵活性、性价比和可推广性。更多还原

【Abstract】 Location-based service network for mobile emergency management is constructed according to the application requirements and specific features of border public safety and emergency responding.The network realizes mobile emergency monitoring and commanding based on the Beidou terminal,GPS terminal,intelligent PDA,Beidou satellite communication networks,and China GSM network.Beidou vehicle-type receiver is used as the access module in the service center(instead of Beidou command-type receiver) to receive other Beidou terminals’ location and information,in order to reduce the Beidou networking applications cost.The location and information fusing and exchanging technology between Beidou terminal and GPS terminal is developed and the networking method is studied to realize the functions such as task forcing,information exchanging, neighborhood location exchanging,command dispatching,etc..So the personnel,vehicles, and materials can be monitored in none ground mobile communication signal coverage areas(such as deserts,Gobi,border,etc.).In the emergency location-based service network, PDA terminals can communicate with Beidou terminals,and can monitor and command other GPS and Beidou terminals based on mobile GIS.The network provides the viable solution for emergency management,which in face of the problems of location sharing, team cooperation,and mobile commanding in the accident and disaster site.The system and technology has been used in X divisions of the Xinjiang Production and Construction Corps. The trial run shows that the systems and technology can meet the basic needs of the border emergency response,and has good flexibility,high cost-effective and good replicability.更多还原
