The invention discloses an intelligent alarm device and method for avoiding train collision, and belongs to the technical field of intelligent alarm. The device comprises an ultrasonic sensor, a PLC control system and a broadcasting system; the two sets of ultrasonic sensors are arranged at the train stopping position in a working area and the edge of an early warning area outside the working area respectively, keep a preset distance from a track and are used for detecting whether obstacles exist on the track or not. The PLC control system is connected with the ultrasonic sensor through a control cable and is used for judging whether the obstacle is a train or not and judging whether the train moves or not; the broadcasting system is in signal connection with the PLC control system, and when the broadcasting system receives an alarm signal sent by the PLC control system, a warning sound is given out; the implementation cost is reduced, the construction difficulty is reduced, and the service life of the sensor is prolonged; workers can be timely notified to effectively and quickly evacuate, and safety accidents are avoided.

    本发明公开了一种避免火车碰撞的智能报警装置及方法,属于智能报警技术领域,所述装置包括超声波传感器、PLC控制系统、广播系统;超声波传感器设有两组,分别设置在工作区域中火车停靠位置及工作区域外的预警区域边缘,且与轨道保持预设距离,用于检测轨道上是否存在障碍物;PLC控制系统通过控制线缆和超声波传感器连接,用于判断所述障碍物是否为火车,以及判断火车是否移动;广播系统和PLC控制系统信号连接,当广播系统接收到PLC控制系统发来的报警信号时,发出警示音;降低了实施费用,降低了施工难度,延长了传感器的使用寿命;能够及时通知工作人员有效快速撤离,避免安全事故的发生。
