FIELD: railway automatics and telemechanics.
SUBSTANCE: control device of automatic crossing warning system comprises two distributed fibre-optic sensors. Sensors are located at approach section on both sides of railway track. Outputs of fibre-optic sensors are connected to input of polling module. Output of polling module is connected to input of control unit of train movement and control of crossing signalling. Output of the parameter control unit is connected to the input of the interface device. Output of the interfacing device is connected to automatic crossing signalling devices.
EFFECT: higher accuracy of determining parameters of train movement when approaching intersection with highway and reduced time of closed crossing state.
