The invention discloses an intelligent alarm method for a flat aisle of a goods yard. The method comprises the following steps: respectively detecting approaching information of locomotives on two sides of the flat aisle through two groups of vehicle detection sensors, sending a locomotive approaching signal to a receiving controller, and controlling lifting of a grade crossing handrail, wherein the sensors comprise a first sensor and a second sensor; when the first sensor firstly detects a locomotive coming signal, sending the signal to the receiving controller, and controlling the grade crossing handrail to fall off; when any sensor detects a locomotive coming signal, locking the output of the other sensor in the same group, and releasing the locked state of the other sensor in the same group until the detection signal disappears for 5 seconds; and when the last section of the locomotive is driven away from the grade crossing, sending a locomotive leaving signal to the receiving controller after a detection signal of a third sensor disappears for 5 seconds, and controlling the handrail to rise.The coming direction of the locomotive can be monitored in real time, the coming signal can be intelligently alarmed, the false alarm condition is prevented, and the safety of the flat aisle is guaranteed.
本发明公开了一种货场平过道智能报警方法,通过两组车辆探测传感器分别探测平过道两侧机车接近信息,并将机车来临信号发送给接收控制器控制道口栏杆升降,包括第一传感器和第二传感器;当第一传感器首先探测到机车来临信号时,信号发送至接收控制器控制道口栏杆落杆;当任意一个传感器检测到机车来临信号时,同组的另一个传感器输出锁死,直至检测信号消失5秒后,解除同组另一个传感器锁死状态;当机车最后一节车辆驶离道口时,第三传感器检测信号消失5秒后,向接收控制器发送机车离开信号,控制栏杆升起,本发明能够实时监测机车来临方向,智能的对来临信号进行报警,且防止误报情况的发生,保障了平过道的安全性。
