[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.
