DEVICE FOR proximity alert TRAIN TO THE PLACE OF REPAIR WORK TRACK

摘要

The utility model is aimed at improving the reliability of the device and reducing injuries in the manufacture of repair track work indicated technical result is achieved in that the device for warning of the train approaching the place of repair trackworks comprises a fixed terminal installed on the locomotive and a mobile terminal located at the repair team that connected to each other by radio. The stationary terminal includes a transmitter to transmit antenna, the sensor current locomotive coordinates, receiver, control unit, display unit, a signaling unit and emergency braking connected to each other as follows. Yield sensor current locomotive coordinates connected to the transmitter input and to the input of the control unit, the receiver output coupled to an input of control unit, first control unit output is connected to the input of the alarm unit, the second output of the control unit - to the input of the indication unit, the third output - to the input of the emergency unit inhibition, fourth output of the control unit via switches "even" or "odd" direction is connected to the input of the transmitter. The mobile terminal includes a sensor current position track brigade, a transmitter, a control block, the even and odd direction indication unit receivers alarm unit, the output of the track team sensor current coordinates connected to the input of the control unit and the input of the transmitter output unit "even" receivers and "odd" direction is connected to an input of control unit, first control unit output is connected to the input of the indication unit, the second output of the control unit - to the input of the alarm unit, the third output block simp phenomenon - the first input of the transmitter, the fourth output of the control unit through switch "free path" is connected to the second input of the transmitter.
