The invention belongs to the field of safety early warning, and provides a laser correlation early warning system for preventing a train from derailing, which comprises a main control room, and a detection unit and a station alarm unit connected with the main control room, the method comprises the following specific steps that S1, the detection units are installed on the two sides of a track; s2, when the detection unit detects the derailing condition, data information is transmitted to a master control room; s3, after the master control room receives the derailment signal, warning is conducted through a station alarm unit; s4, the overall reliability of the detection unit is evaluated and detected; the reliability of the detection unit is calculated by combining a fault mode and an effect analysis result and adding an evaluation mechanism, the detection unit can be timely and accurately maintained without consuming more manpower and material resources, a threaded rod and a telescopic lead screw are matched to drive the laser correlation device to perform secondary lifting, and the reliability of the detection unit is improved. The heat dissipation performance during working is guaranteed, meanwhile, the sealing protection performance during non-working is improved, and the service life of the device is prolonged.
本发明属于安全预警领域,提供了防止列车脱轨激光对射预警系统,包括主控室,以及与主控室相连接的检测单元和车站报警单元;具体步骤如下:S1、将检测单元安装在轨道两侧;S2、检测单元检测到脱轨情况时将数据信息传输至总控室;S3、总控室在接收到脱轨信号后,通过车站报警单元进行示警;S4、对检测单元的整体可靠性进行评估检测;本发明通过结合故障模式和效果分析的结果加入评估机制来计算检测单元的可靠性,可以在不消耗更多人力物力的情况下,及时准确地进行检测单元的维护工作,通过螺纹杆与伸缩丝杆配合驱动激光对射器二级抬升,保证工作时散热性能的同时,提高不工作时的密封防护性能,延长装置的使用寿命。
