With the rapid development of railway freight transportation industry, it is imperative for information and intelligent logistics management to replace the traditional logistics management technology. This paper proposes the design of high-speed railway material positioning system based on UWB technology. Firstly, the difficulties of UWB implementation in high-speed railway freight positioning are analyzed. In order to solve the characteristics of nonlinear and non Gaussian distribution of multi-path interference, this paper presents a particle filter ranging calibration algorithm for serious multipath interference in train compartment, which has serious multipath interference, processes 25 sets of ranging data with particle filter. Finally, by arranging 6 base stations in the high-speed railway carriage, the multi-base station weighted least square method is used to locate the information of the material location in the carriage. The feasibility of the system is verified by comparing with the real location.
