【摘要】：随着互联网的持续火热以及线上线下电子商务(O2O)市场日益火爆,我们即将迎接数据时代的到来,人们对数据的要求越来越高,这迫切的催生出无线定位精度不断地提升以满足市场对室内终端无线定位的需求,新一代室内无线定位系统的开发迫在眉睫。传统的室内无线定位系统对终端的定位精度不够完美,很难满足企业对终端的管理,为了更好地服务客户,企业需要及时了解客户终端的实时数据,在这种背景下,丘比特(CUPID)无线定位系统应运而生,通过应用目前比较前沿的过滤技术和相关算法来满足企业对终端定位的一系列需求。本文研究了国内外目前无线定位系统的发展现状,并详细介绍了一些市面上主流的无线定位产品,阐述了无线定位系统的相关基本概念、原理和方法,介绍了无线定位的相关技术;分析了CUPID无线定位系统一系列业务和性能需求,并针对这些需求进行详细的分析,确定CUPID无线定位系统提供的一系列服务,并对系统功能模块进行划分;给出了系统的应用架构设计,设计了系统多个不同功能模块的实现方法。CUPID无线定位系统分为数据收集功能模块、数据处理功能模块和数据过滤功能模块,其中数据收集功能模块又细划分为AP信道切换和部署、定位AP选择以及数据收集三部分,数据处理模块包括傅里叶变换、RSSI距离和RTT距离计算以及终端坐标计算三部分,数据过滤模块由RTT过滤和卡尔曼滤波两部分组成,各模块协调合作,共同完成CUPID无线定位系统对终端的定位。本文是结合自己所参与的H3C公司CUPID无线定位系统项目的开发,在数据收集模块作者详细介绍了AP信道切换和部署和AP选择功能,在数据处理模块详细介绍了RSSI距离计算中衰减公式中衰减系数的计算,在数据过滤模块详细介绍了根据一系列过滤准则过滤出有效地RTT。本文最后详细的介绍了一系列对CUPID无线定位系统的各项功能的测试结果,各项测试结果表明CUPID无线定位系统能够满足目前市场上各种类型终端的定位要求,并且定位精度在接收范围之内,尤其对于IPhone终端定位精度超过预期的效果,很好的满足目前企业对各种终端定位数据的采集。目前CUPID定位系统在国内一些大型广场已投入使用,并且实践效果得到用户的一致认可,在国外某些国际机场也已投入使用,取得了良好的效果。
[Abstract]:With the continued popularity of the Internet and the increasing popularity of the online and offline electronic commerce (O2O) market, we are about to welcome the arrival of the data age, and people are demanding more and more data. This urgent birth of wireless positioning accuracy to meet the market demand for wireless positioning of indoor terminals, the development of a new generation of indoor wireless positioning system is imminent. The traditional indoor wireless positioning system is not perfect enough to locate the terminal, so it is difficult to meet the management of the terminal. In order to better serve the customer, the enterprise needs to know the real-time data of the customer terminal in time. The Cupid Cupid wireless positioning system emerges as the times require. By using the advanced filtering technology and related algorithms, the enterprise can meet a series of requirements for terminal location. This paper studies the development of wireless positioning system at home and abroad, introduces some mainstream wireless positioning products in the market, and describes the basic concepts, principles and methods of wireless positioning system. The related technologies of wireless positioning are introduced, a series of business and performance requirements of CUPID wireless positioning system are analyzed, and a series of services provided by CUPID wireless positioning system are determined by analyzing these requirements in detail. The system function modules are divided, and the application architecture design of the system is given, and the realization method of several different function modules of the system is designed. The CUPID wireless positioning system is divided into data collection function modules. Data processing function module and data filtering function module, in which data collection function module is divided into AP channel switching and deployment, positioning AP selection and data collection. The data processing module includes three parts: Fourier transform RSSI distance and RTT distance calculation and terminal coordinate calculation. The data filtering module consists of RTT filter and Kalman filter. Joint completion of CUPID wireless positioning system to the terminal positioning. Combined with the development of CUPID wireless positioning system project of H3C company, this paper introduces the function of AP channel switching and deployment and AP selection in detail in the data collection module. In the data processing module, the calculation of the attenuation coefficient in the attenuation formula of the RSSI distance calculation is introduced in detail. In the data filtering module, the effective RTT filtering based on a series of filtering criteria is introduced in detail. At the end of this paper, a series of testing results of CUPID wireless positioning system are introduced in detail. Each test result shows that CUPID wireless positioning system can meet the positioning requirements of various types of terminals in the market at present. And the positioning accuracy is within the receiving range, especially for the IPhone terminal positioning accuracy exceeding the expected effect, which is very good to meet the current enterprise to a variety of terminal positioning data collection. At present, the CUPID positioning system has been put into use in some large squares in China, and the practical effect has been unanimously recognized by the users, and has also been put into use in some international airports abroad, and good results have been obtained.
