摘要
在轨道交通领域,如何提升列车运行净空安全成为目前运营的迫切需求。当前快速发展的人工智能技术、传感器技术以及无人驾驶技术为解决上述问题奠定技术基础。文章介绍一种轨道交通远程瞭望系统,其基于车载感知系统,采用障碍物识别、列车速度测量和三维地图构建3种技术感知列车周围的环境,并运用车路协同感知系统实现路侧与车侧协同感知,判断前方线路情况,从而指导司机行车或采取防护措施,提高列车的运行安全性。
In the field of rail transit,how to improve the safety of train operation clearance has become an urgent need for the operation.The rapid development of artificial intelligence technology,sensor technology and FAO driving technology has laid a technical foundation for solving the above-mentioned problems.This paper introduces a long-distance observation system of rail transit.Based on the on-board sensing system,it uses three technologies to perceive the environment around the train by using obstacle identification,train speed measurement and three-dimensional map construction.The train-track cooperative sensing system is used to realize the collaborative perception of trackside and vehicle-borne,judge the situation of the tracks ahead,and guide the driver to operate or take protective measures,in order to improve the train operation safety.
