基于新一代北斗的中欧班列铁路集装箱定位追踪技术研究OA

Based on an investigation of the current application status of the BeiDou Navigation Satellite System in railway container transportation,this paper addresses the challenges of real-time tracking and positioning of China Railway Express containers under conditions of metal-shielding,cross-border long-distance transportation,and harsh environments.A container positioning device design scheme based on BeiDou-3 positioning technology was proposed.By integrating antenna optimization,radio frequency enhancement,and intelligent algorithm technologies,the solution resolved multipath interference caused by the container structure and the difficulty of rapid satellite acquisition at startup.Furthermore,the integration of high-efficiency photovoltaic charging,intelligent precision power management,and low-temperature charging technologies resolved the critical challenges of achieving ultra-low power consumption and ultra-long endurance of the positioning device.Based on data collected from China Railway Express operations,key performance indicators of the positioning device,including transmission integrity,satellite acquisition time,acceleration,battery level,and ambient temperature,were evaluated.The results show that the new-generation BeiDou-based positioning technology provides strong technical support for container asset management,transportation safety,logistics services,and operational management.
