【摘要】 随着无线网络的发展,地理信息突破了无法随身携带的限制,可以通过手持设备获取对象的地理信息。讨论了多用户GPS移动定位追踪系统的研究与设计。该系统的设计基于C/S结构,采用移动端智能系统、Socket通信、多线程等方法,把数据传输到中心数据库服务器;用户可以从屏幕上实时观察、精确定位多个对象(包括个人,车辆等)的地理位置,计算行进速度,并且可以看出运动轨迹等。这套系统可以应用于应急疏散、油气井、化工厂、军工等各个安全生产领域。更多还原

【Abstract】 The study and design of multi-user GPS mobile locating and remote tracking system based on C /S structure were discussed. By using Windows mobile,socket,and multi-thread methods,the client could acquire and locate the geographic positions and velocities of multi objects(including person,automobile and so on) precisely and real-time,then the data could be transferred to center database. The users could see the positions and moving tracks of all objects from map,and the multi-user monitoring and tracking were realized. The system could be applied to emergency evacuation,oil field,chemistry factors,war industry and other safety fields.更多还原
