摘要: 铁路上道作业过程中,当有列车接近时,为避免列车与人员、机具发生碰撞,施工人员须停工下道,因此,准确可靠地列车接近预警对铁路施工安全非常重要。将二次雷达技术应用于列车接近预警,对系统应用场景进行分析,对雷达通信模块工作原理及通信方案进行了重点阐述,对车载、地面装置结构进行设计。经过试验,基于二次雷达的列车接近预警系统满足铁路施工作业要求。

Abstract: During on-track railway construction operation, the construction personnel have to leave the track when a train approaches, to avoid collision between the train and the personnel and machinery. Therefore, accurate and reliable train approach early warning is critical for railway construction safety. This paper describes the application of the secondary radar technology to train approach early warning. It presents an analysis of the system application scenarios, a description of the working principles and communication scheme of the radar communication module, and proposes a design of the onboard and wayside devices. The test results show that the train approach early warning system based on secondary radar meets the requirements in railway construction operation.

Key words: secondary radar, train, approach early warning
