【摘要】：移动终端的定位和导航功能是移动互联的核心内容，在军事和民用各个领域对于定位导航服务都提出了更高的要求。但是目前没有一种导航卫星系统能够独立满足室内、室外环境中无缝定位的要求，因此定位导航系统必然会由单一信号转变为多种模式信号融合的导航模式。本课题针对以上分析并结合实际需求，计划研究和实现融合北斗与GPS以及无线信号定位功能的移动定位导航系统，在室外环境中通过GPS和北斗系统双模精确定位，在室内环境中根据无线信号定位，实现移动终端多模式无缝定位。本文开展研究内容如下： 1)研究了现有定位技术和定位系统，对目前无线定位技术工作原理以及混合定位技术进行了研究； 2)构建了系统终端部分的平台架构，根据实际需求选取的三星S5E4412开发板，GYM多模卫星接收模块；软件平台采用Android操作系统。 3)分析定位数据从硬件接收模块到电子地图显示以及上报服务平台的整个流程，设计实现了多模无缝定位模式，以及自主选取定位模式； 4)对Apache MINA通信架构和基于Spring、Struts、Hibernate的Java EE开源架构进行了研究和整合，实现具有高并发请求处理能力的TCP服务器，和高兼容性的WEB服务器。 5)研究了终端和定位服务平台的通信过程，实现安全、高效的数据通信。本系统创新之处在于实现了移动设备的多卫星接收模式，摆脱了定位终端对于GPS系统的过度依赖，解决单独依赖于GPS系统的定位终端设备可靠性低、安全性受限的问题，同时采用多模混合定位模式实现了定位精度的进一步提升；本系统实现了在室内环境中的无线信号定位，，使用户能够在任何时间、任何位置获取定位导航服务，满足了更高的定位导航服务要求；本系统可用于定位导航的同时还可以通过定位服务平台实现终端位置监控和安全通信，具有很好的应用价值。
[Abstract]:The location and navigation function of mobile terminal is the core content of mobile interconnection. In military and civilian fields, positioning and navigation services have been put forward higher requirements. But at present, no navigation satellite system can independently meet the indoor and outdoor environment seamless positioning requirements. Therefore, the positioning and navigation system will change from a single signal to a multi-mode signal fusion navigation mode. According to the above analysis and the actual needs, this paper plans to research and implement the mobile positioning and navigation system which integrates Beidou and GPS and wireless signal location function. In the outdoor environment by GPS and Beidou system dual-mode accurate positioning in the indoor environment according to the wireless signal location the mobile terminal multi-mode seamless positioning. The contents of this paper are as follows: 1) the existing positioning technology and positioning system are studied, and the working principle of wireless positioning technology and hybrid positioning technology are studied. 2) the platform architecture of the terminal part of the system is constructed, and the GYM multi-mode satellite receiving module is selected according to the actual demand of the Samsung S5E4412 development board. The software platform adopts Android operating system. 3) analyzing the whole flow of location data from hardware receiving module to electronic map display and reporting service platform, designing and realizing the multi-mode seamless positioning mode, and choosing the localization mode independently; 4) Research and integration of Apache MINA communication architecture and Java EE open source architecture based on Spring Struts hibernate. Implementation of high concurrent request processing capacity of TCP server, and high compatibility of WEB server. 5) the communication process between terminal and location service platform is studied to realize secure and efficient data communication. The innovation of this system lies in the realization of the multi-satellite receiving mode of mobile equipment, which gets rid of the excessive dependence of positioning terminal on GPS system, and solves the problem of low reliability of positioning terminal equipment relying solely on GPS system. At the same time, the multi-mode hybrid positioning mode is used to improve the positioning accuracy. The system realizes the wireless signal positioning in the indoor environment, enables the user to obtain the positioning and navigation service at any time and any location, and meets the higher requirements of the positioning and navigation service. This system can be used to locate navigation and realize terminal position monitoring and secure communication through positioning service platform, which has good application value.
