The invention discloses a rail train approach alarm device and method, and relates to the technical field of rail train detection. The device comprises ground end equipment and vehicle-mounted end equipment, the ground end equipment and the vehicle-mounted end equipment can measure the distance between a ground construction area and a traveling train in real time, and the distance measurement limit is not less than 3.5 km; and when the distance measured by the ground end equipment and the vehicle-mounted end equipment is smaller than or equal to the early warning distance, respective alarms are started to give an alarm, so that a train driver is reminded to control the train to slow down in time, and constructors on the road get off the road to avoid danger. According to the method, positioning beacons do not need to be additionally laid, a train operation monitoring system does not need to be matched, cost is reduced, meanwhile, train-ground distance measurement is achieved through radar secondary inquiry, and measurement inaccuracy caused by environmental interference is avoided.
本申请公开了一种轨道列车接近报警装置和方法,涉及轨道列车检测技术领域。所述装置包括地面端设备和车载端设备;所述地面端设备和车载端设备均能够实时测出地面施工区和行进列车之间的距离,且距离测量极限不小于3.5km;且所述地面端设备和车载端设备在测量得到的距离小于等于预警距离时,均会启动各自的报警器进行报警,以及时提醒列车驾驶员控制列车减速,道上施工人员下道避险。本申请无需额外铺设定位信标,也不需要配套列车运行监控系统,降低了成本,同时利用雷达二次问询实现车地距离测量,避免了环境干扰造成的测量不准确。
