铁路专用北斗定位测试:从需求、愿景到挑战、机遇
Testing of BDS-based positioning for railway:From requirements,vision to challenges,opportunities
摘要
Abstract
With the continuous evolution of intelligent railway systems,novel railway applications based on spatiotemporal information from the BeiDou Navigation Satellite System(BDS)have gar-nered significant attention.However,the lack of dedicated testing systems tailored to specific railway applications makes it difficult to meet the full lifecycle requirements of BDS-based railway systems.To address this problem,this paper focuses on exploring the requirements and development potential for specialized testing and evaluation of BDS-based railway applications.It investigates how to lever-age effective mechanisms to build dedicated testing instruments and system environments that address the unique characteristics of the railway industry,thereby meeting the full lifecycle needs of BDS-based railway systems.First,existing relevant work is surveyed and summarized,outlining the devel-opment needs and vision for dedicated testing of BDS-based positioning in railway.Second,a compre-hensive overall architecture for a dedicated railway BDS positioning testing system is established,cen-tered on the concept of"zero-on-site testing".This architecture aims to adopt a modular approach and inter-connected collaborative mechanisms to forge a new pathway that balances conventional satellite positioning testing paradigms with the application characteristics of the railway industry.Third,this pa-per uses the train positioning unit of a specific type of train control system as a test subject example,detailing the setup of the dedicated test system and the implementation of testing.Finally,this paper analyzes and summarizes the research challenges that may arise in providing comprehensive and reli-able testing and evaluation for the progressively developing applications of BDS in railway,offering corresponding approaches.The research results indicate that constructing a dedicated railway BDS po-sitioning testing system can effectively enhance testing coverage,flexibility,adaptability,and compat-ibility,thereby providing strong support for the deep application of BDS in the railway industry.关键词
