Research On UWB High Precision Positioning Technology Based On Internet Of Things

To assist the smart park to establish a comprehensive management platform to realize information integration and sharing,ultra-wideband technology and indoor positioning technology are used to realize real-time monitoring of personnel,materials and equipment inside the park and improve the management level inside the park.In this paper,the three-dimensional positioning model is studied in combination with the Internet of Things technology,the location information collection terminal is designed,and the real-time location monitoring cloud platform is designed to monitor the location information in real time.The main research contents of this thesis are as follows:(1)Research on ultra-wideband positioning model,and realize the research and simulation of 3D positioning model.The Fang and traceless Kalman filter synthesis algorithm is studied,and the positioning accuracy is verified by Matlab experiments.(2)Complete the design of the location information acquisition terminal.The terminal uses XR-50 A module as the main control core and UWB module uses DWM1001,completes the basic circuit design and the program design of the work of each module,realizes the acquisition of location information and the logical realization of data uploading into the network based on Io T network layer.(3)Complete the design of the real-time location monitoring cloud platform based on the Io T application layer.Firstly,the demand analysis of the cloud platform system is carried out and B/S architecture is adopted.The back-end is responsible for various logic processing and database storage inside the system,using Spring Boot framework to complete the back-end design,using My Sql database to store data,the system provides user management,device management,map management and location information display and other functions;the front-end is designed and completed using Java Script,CSS,HTML and other languages to realize the visualization of system information.Through testing the functional modules and positioning effect of the system,the feasibility of the design scheme of this paper is verified,and the real-time collection and dynamic monitoring of the location information is realized.
