FIELD: railway automation.
SUBSTANCE: invention relates to means of railway automation for monitoring emergency situations at unguarded level crossings. The system has a crossing part, which includes an optocoupler (1), a rail circuit (3) and a control device (2), a transmitting device (4) of the Automatic Locomotive Signalling system and a locomotive part including a receiving device (5) of the ALS system and a locomotive traffic light (6). Moreover, the outputs of the optocoupler (1) and the track circuit (3) are connected to the inputs of the control device (2), connected by its output to the input of the transmitting device (4) of the ALS system, connected by its output to the input of the receiving device (5) of the ALS system, connected by its output to the entrance of the locomotive traffic light (6).
EFFECT: increased reliability of the control system at unguarded level crossings through the use of a standard als system for information transmission.
