The invention discloses an early warning method and an early warning system, and belongs to the technical field of railway equipment. The method comprises the following steps: continuously receiving distance signals sent by a train in the process of driving towards a target point; monitoring the distance between the train and the target point in real time according to the distance signal; when the distance between the train and the target point is smaller than or equal to a first preset safety distance, a first warning signal is generated, and first-level early warning is carried out according to the first warning signal; and when the distance between the train and the target point is smaller than or equal to a second preset safety distance, a second warning signal is sent out, and secondary early warning is carried out according to the second warning signal. According to the method, multi-level early warning is set before the train arrives at the target point (construction site), and early warning is carried out in a linkage broadcast mode, so that the coverage and the receiving crowd of the alarm are expanded, the protection is more systematic and comprehensive, and the early warning effect is improved.

    本申请公开了一种预警方法及预警系统,属于铁路设备技术领域。所述方法包括:持续接收列车在向目标点行驶的过程中发送的距离信号;根据距离信号实时监测列车与目标点间的距离;当列车与目标点间的距离小于或等于第一预设安全距离时,生成第一警示信号,根据第一警示信号进行一级预警;当列车与目标点间的距离小于或等于第二预设安全距离时,发出第二警示信号,根据该第二警示信号进行二级预警。该方法,在列车到达目标点(施工现场)前设置了多级预警,并采用联动广播的形式进行预警,扩大了警报的覆盖面和接收人群,使得防护更系统、更全面,提高了预警效果。
