针对应急管理中对信息共享、团队协作和移动指挥的应用需求,研究了移动应急终端间的位置共享与信息交互方法和技术框架,初步构建了移动应急位置服务网.移动应急位置服务网包括移动应急终端、无线通信网络、中心服务器、监控终端和管理终端等组成部分.定义了位置、信息与指令传输格式,以实现移动应急终端和中心服务器之间的实时通信.制定了移动应急终端组网规则,以实现位置和信息在移动应急位置服务网内的交互.研发了友邻位置与信息交互技术,重点研究了终端位置报告、终端节电、北斗终端接入、友邻位置表达、信息推送等技术.针对具体应用需求,开发了原型系统,试验表明移动应急友邻互视技术可提高事发现场应急处置团队的协作能力和应急处置效率,具有实用性.%The method and technical frame of mutual visualization and information sharing technology among mobile emergency terminals were proposed, and the location-based service network for mobile emergency management was initially developed, in order to resolve the problems such as information sharing, team cooperation, and mobile commanding in face of the emergency management in the accident or disaster field. The transfer format for location,information, and command was defined for the network communication between the terminals and the server. The terminal networking rule for mobile emergency response was established to realize the location and information sharing in the mobile emergency location-based network. The rule consisted of three kinds of networking method:networking method by the commanding center, networking method by the single emergency response department, and networking method by the distance between the applicant and other terminals. The key technologies of mutual visualization and information sharing, such as terminal location real-time reporting, terminal power saving according to the received GPS status and working characteristics, Compass terminal accessing, neighbors' location displaying and information pushing, were mainly developed and resolved. A prototype system was constructed according to the practice requirements. The test run showed that the mutual visualization technology can improve the team cooperation capability and the efficiency. The technology has the practical applicability.
