The invention discloses a historical moving trajectory and Beidou navigation integrated positioning method and device. The method comprises the following steps: receiving longitude and latitude information sent by a Beidou navigation system; judging the validity of the historical track information by combining the received longitude and latitude information and the corresponding historical track information; when the historical track information is valid, searching alternative sections according to the type of the terminal; traversing the alternative sections, and converting longitude and latitude to section position information; judging whether the converted section position information in the alternative sections is valid or not according to the terminal type; and when the converted section position information is valid, outputting the section position information. The method has the advantages that the historical track information of the terminal is fully utilized for calculation, the calculation amount of processor equipment is greatly reduced, and the compression rate can reach 98% or higher; and meanwhile, the CPU utilization rate is also improved, the server with the same configuration can perform calculation tasks of a larger station, more stations and more terminals, and the hardware investment cost is saved.

    本发明公开了一种融合历史运行轨迹和北斗导航的定位方法及其装置,该方法包含:接收北斗导航系统发送的经纬度信息;结合接收的经纬度信息和对应的历史轨迹信息,判断历史轨迹信息的有效性;当历史轨迹信息有效时,根据终端的类型搜索备选区段;遍历备选区段,进行经纬度向区段位置信息的转换;根据终端类型,判断备选区段中转换的区段位置信息是否有效;当转换的区段位置信息有效时,输出此区段位置信息。其优点是:该方法充分利用终端的历史轨迹信息进行计算,大幅减少了处理器设备的计算量,压缩率可达到98%或更高;同时其还提高了CPU利用率,同样配置的服务器可以进行更大车站、更多车站、更多终端的计算任务,节省了硬件投入成本。
