Claims (1)

The invention relates to railway automation, in particular to devices for preventing the entry of vehicles into the intersection of the highway with the railway track. The technical result - ensuring the safety of trains and vehicles. Sequential rise at an angle away from the railway track of the covers of the barriers, blocking the highway across its entire width and preventing the vehicles from entering the crossing zone as the train approaches it, as well as ensuring that vehicles leave the area in any situations, automatically monitoring the presence of vehicles in the area above using a ultrasonic sensor to prevent the switch of the electric motor and the possibility of lifting the barrier of the barrier at the time of following vehicles moving through the mouth. If the vehicle is located in the area above the barrier of the barrier, the sensor blocks the motor to turn on to lift the barrier cover. When a vehicle is removed from the lid surface area or when the sensor is disconnected, such a lock is removed. Control of the presence of obstacles to the movement of the train in the area of the crossing is carried out automatically using microwave sensors (microwave sensors) located on supports mounted on the verges of the crossing. If there are no signals on the train approaching, the outputs of these sensors are blocked and the lamps do not light up at the barriers.
