【摘要】：位置信息服务在人们的日常生活与工作学习中扮演着重要的角色。随着信息技术的发展,人类对位置信息服务的需求也达到了一个前所未有的高度。位置信息服务提供导航与定位功能,包括室外导航定位和室内导航定位。目前,基于GPS全球定位系统的室外导航定位技术已经十分成熟,且得到了广泛应用。但与GPS功能类似、有着自主知识产权的北斗导航定位系统在定位终端的小型化设计方面效果仍然不够理想。此外,建筑物内部等导航卫星信号无法覆盖到的室内一直以来都是导航定位技术的盲区。即当前室内导航定位技术的研究与发展不够成熟,仍然处于早期功能不够完善的初级阶段。室外导航定位与室内导航定位是一个有机体,但目前缺乏一个系统的平台将室内外导航定位完全地整合在一起。本文尝试将室内外导航定位技术融合在一起,结合当前主流的服务器开发与定位终端Android应用开发技术,设计与实现了一个室内外无缝导航定位系统演示平台。为了实现上述系统,本论文做了如下工作:搭建一个能够提供Web服务的服务器。通过该服务器,普通用户可以在线查看定位终端的室外位移轨迹在Google Maps等电子地图上的显示,以及室内位移轨迹在建筑物平面图上的显示;开发一款基于Android智能手机的定位终端应用程序,用于采集和上传定位终端的GPS坐标信息和室内位置信息至上述Web服务器;设计与实现了基于微带线技术的小型化北斗天线,该天线有助于实现定位终端的便携性等特性。其中,服务器端的开发基于开源的GPS定位系统Traccar,采用了Web应用程序开发框架GWT,从而大大地降低了开发的难度和成本。定位终端的Android应用程序,能够同时采集室内外位置数据,并上传到服务器的数据库中。既方便了对位置数据的管理,又可以通过网页浏览器实时在线查看,从而实现对定位终端位置信息的监控和追踪。通过上述工作,本系统良好地展示了室内外无缝导航定位技术。
[Abstract]:Location information service plays an important role in people's daily life and work and study. With the development of information technology, human demand for location information services has reached an unprecedented height. Location information services provide navigation and positioning capabilities, including outdoor navigation and indoor navigation. At present, outdoor navigation and positioning technology based on GPS global positioning system has been very mature, and has been widely used. But similar to the function of GPS, Beidou navigation and positioning system with independent intellectual property rights is still not ideal in miniaturization design of positioning terminal. In addition, navigation satellite signals such as buildings can not cover the indoor has always been the blind spot of navigation and positioning technology. That is, the current research and development of indoor navigation and positioning technology is not mature, still in the early stage of incomplete function. Outdoor navigation and indoor navigation is an organism, but there is a lack of a systematic platform to integrate indoor and outdoor navigation. This paper attempts to combine the indoor and outdoor navigation and positioning technology together, combined with the current mainstream server development and positioning terminal Android application development technology, designed and implemented a seamless indoor and outdoor navigation and positioning system demonstration platform. In order to realize the above system, this paper has done the following work: build a server that can provide Web service. Through the server, the ordinary users can view the display of the outdoor displacement track of the positioning terminal on the electronic map such as Google Maps and the display of the indoor displacement track on the building plan. A positioning terminal application program based on Android smart phone is developed to collect and upload the GPS coordinate information and indoor position information of the positioning terminal to the above-mentioned Web server, and a miniaturized Beidou antenna based on microstrip line technology is designed and implemented. The antenna is helpful to realize the portability of the positioning terminal. Among them, the server-side development based on the open source GPS positioning system Traccar, adopts the Web application development framework GWT, which greatly reduces the difficulty and cost of development. Location terminal Android application, can simultaneously collect indoor and outdoor location data, and upload to the server database. It not only facilitates the management of location data, but also can be viewed online in real time through the web browser, thus realizing the monitoring and tracking of location information of positioning terminal. Through the above work, the system well demonstrated the indoor and outdoor seamless navigation and positioning technology.
