摘要:
［目的］为解决现有被动式检测方法在检测轨行区侵限障碍物时的滞后性问题，给列车制动预留更多的反应时间，降低列车事故发生率，减轻事故后果，需研究列车车载轨行区障碍物主动式探测技术。［方法］通过多种传感器、多检测子任务组合同多个列车信号系统单元的联合，提出了一种主动检测轨行区是否有侵限障碍物的列车车载系统，并在平直轨行区内采用该系统对不同障碍物进行了试验，得到不同障碍物的有效识别距离。［结果及结论］该障碍物系统可为列车提供自主感知能力，在前方轨行区出现侵限障碍物时，能够及时发出报警信息或实施列车制动。

［Objective］ In order to solve the lag problem of current passive detection methods in detecting the obstacles in the area directly related to train running (hereinafter referred to as train running area or TRA), reserve more reaction time for train braking, reduce the incidence of train accidents, and mitigate the consequence of the train accidents, it is necessary to study the onboard active TRA obstacle detection technology. ［Method］ Through uniting the combination of multiple sensors and detection sub-tasks with the train signal system units, an active onboard detection system is proposed to actively detect whether there are obstacles intruding in the TRA boundary. Through testing the above system in the straight TRA with different obstacles, the effective identification distances of the obstacles are obtained. ［Result & Conclusion］ The above system can provide the train with autonomous perception ability, timely sending alarm messages or starting train braking when obstacles intruding in the boundary appear in the front TRA.
