【摘要】：本论文主要设计基于超宽带UWB(Ultra Wideband)的室内定位平台,首先通过调研与分析国内外UWB定位平台的发展现状以及平台设计思想,提出了论文设计的超宽带室内定位平台的架构模型,并给出了定位服务端软件的设计思想和客户端应用控制软件的构建思想,描述了系统中各部分组成的功能模块和相互作用,并利用平台后端设计的定位算法来完成对室内移动目标的定位并在平台上实时显示和查看。定位服务软件的主要功能包括数据的接收与存储、网络中基站的注册与发现、与客户端应用层、客户端控制层的通信以及数据的处理。数据的存储结构主要采用红黑平衡树算法来存储基站与标签的信息,其中网络中基站的发现采用基于MDNS协议的网络发现功能。数据处理层获得TOA信息后,利用TDOA算法处理距离信息,最终得到移动标签在室内的位置坐标信息。客户端应用控制软件的构建,其主要应用Qt框架。控制接口用来建立与监控TCP Socket成功与定位服务器相连。TCP Socket编程的优势在于能够获得基于TCP/IP协议的可靠地通信。客户端显示窗口设计包括基站信息的配置窗口和标签的显示窗口,它主要由客户端控制层进行控制。而Qt Designer是一款配置并设计Qt组件和用户自定义组件的设计工具,它可以在QtCreator IDE工具中运行,也可以独立运行。通过测试表明,本论文设计的定位平台已经能够满足数据的传输以及定位精度的要求。
[Abstract]:This paper mainly designs the indoor positioning platform based on UWB UWB(Ultra Wideband. Firstly, by investigating and analyzing the current situation of UWB positioning platform at home and abroad and the design idea of the platform, the architecture model of UWB indoor positioning platform designed in this paper is put forward. The design idea of the software and the construction idea of the client application control software are given, and the function modules and interaction of each part of the system are described. The location algorithm designed by the back end of the platform is used to locate the indoor moving target and display and view in real time on the platform. The main functions of the location service software include the receiving and storing of the data. The registration and discovery of the base station in the network, the communication with the client application layer, the communication between the client control layer and the data processing. The data storage structure mainly uses the red-black balanced tree algorithm to store the information between the base station and the label. The discovery of the base station in the network adopts the network discovery function based on MDNS protocol. After the data processing layer obtains the TOA information, it uses the TDOA algorithm to process the distance information. Finally, the location of the mobile label in the indoor coordinate information. Client application control software construction. Its main application QT framework. The control interface is used to establish and monitor the TCP Socket success and locate the server. TCP. The advantage of Socket programming is that it can get reliable communication based on TCP/IP protocol. Client display window design includes configuration window of base station information and display window of label. QT Designer is a tool for configuring and designing QT components and user-defined components. It can run in QtCreator IDE tools or independently. The test results show that the positioning platform designed in this paper can meet the requirements of data transmission and positioning accuracy.
