【摘要】：随着信息时代的到来,通信和导航技术在相互交融中蓬勃发展,数据和多媒体业务也在快速增加,基于位置服务(LBS, Location-Based Services)在大众生活中扮演着越来越重要的角色。新时代纵横交错的道路网络和复杂的生存空间结构使得人们对位置服务的需求愈加强烈,迫切的需要众多智能化的应用和贴心化的一站式服务。基于位置服务在室外环境下的应用已经相对成熟,但是在某些复杂的室内环境下,现有的定位导航技术还很难达到室内位置服务的定位需求。本论文针对在动态WiFi-Mesh网络下的融合定位监视问题展开研究,提出了融合定位监视方法并实现了融合定位监视系统,提高了室内定位精度,并且简化了室内定位系统的构建复杂度。本论文的主要工作体现为以下三个方面：(1)提出了一种融合定位监视算法。本算法融合卫星导航定位、惯性导航定位以及高程定位等相关技术,并且运用了多种室内定位数据处理、目标追踪和信息融合算法。(2)组建了可用于室内定位的动态WiFi-Mesh网络。动态WiFi-Mesh网络指的是利用基于Open Wrt智能路由网关节点组建的无线网状结构的WiFi网络环境,可以向处在该网络环境下的网络节点提供WiFi上网服务和室内定位服务。(3)实现了融合定位监视系统。融合定位监视系统是融合定位监视的室内定位算法和动态的WiFi-Mesh网络架构运行的平台,该系统主要由无线网关定位节点、中心位置服务器及定位终端三大部分组成。系统可以实现处于动态WiFi-Mesh网络结构下的无线网关定位节点和定位终端的网络服务和定位服务。本论文的意义在于提高了室内定位的定位精度和简化了室内定位系统的构建复杂度,克服了传统室内定位技术单一化定位和离线式采集部署的缺点,突破了指纹库的在线采集和移动连续追踪等关键技术,实现了高精度的移动目标室内定位系统,可以在大部分的室内环境下灵活动态部署,拥有广阔的应用前景。
[Abstract]:With the arrival of the information age, communication and navigation technology in the blend of vigorous development, data and multimedia services are also rapidly increasing, location-based services LBS. Location-Based Services). New era crisscross road network and complex living space structure make people's demand for location service more and more intense. The application of location-based service in outdoor environment is relatively mature, but in some complex indoor environment. The existing positioning and navigation technology is difficult to meet the location requirements of indoor location services. This paper focuses on the problem of fusion location monitoring in dynamic WiFi-Mesh networks. The fusion positioning monitoring method is put forward and the fusion positioning monitoring system is implemented, which improves the indoor positioning accuracy. And simplify the complexity of the building of indoor positioning system. The main work of this paper is as follows: 1. A fusion positioning and monitoring algorithm is proposed. This algorithm fusion satellite navigation and positioning. Inertial navigation positioning and elevation positioning and other related technologies, and the use of a variety of indoor positioning data processing. Target tracking and information fusion algorithm. The dynamic WiFi-Mesh network which can be used for indoor positioning is constructed. The dynamic WiFi-Mesh network refers to the use of Open based network. The Wrt intelligent routing gateway node constructs the wireless mesh structure WiFi network environment. You can provide WiFi Internet access and indoor location services to network nodes in the network environment.). The fusion positioning and monitoring system is the platform of indoor positioning algorithm and dynamic WiFi-Mesh network architecture. The system is mainly located by wireless gateway. The system can realize the network service and location service of the wireless gateway location node and the location terminal under the dynamic WiFi-Mesh network structure. The significance of this paper is to improve the positioning accuracy of indoor positioning and simplify the complexity of building indoor positioning system. It overcomes the shortcomings of traditional indoor positioning technology, such as single localization and off-line acquisition and deployment, and breaks through the key technologies such as on-line acquisition of fingerprint database and mobile continuous tracking, and realizes a high-precision indoor positioning system for moving targets. It can be deployed flexibly and dynamically in most indoor environments and has a broad application prospect.
