DEVICE FOR AUTOMATIC CONTROL OVER MECHANISM OF AUTO-ENGAGING DEVICES OF FREIGHT CARS FROM SELF-DISENGAGEMENT DURING MOVEMENT OF TRAIN Russian patent published in 2006 - IPC G01B21/16 

FIELD: engineering of railway vehicles, in particular, stationary equipment for controlling auto-engagement parts of freight cars from self-disengagement during movement of train.

SUBSTANCE: device has emitters and photo-receivers, information channel blocks, which are connected to photo-receivers, mounted in angles of photo-matrix sectors. The latter are made in form of parallelograms, identical to projections on photo-matrix of controlled hollows between end surfaces of locks and striking surface of opening of each pair of adjacent automatic-engagement parts. Outputs of information channels are connected to inputs of block, commutating transmission of powering voltage onto electric engines of module drives with mounted laser emitters, maintaining reverse operation of electric engines of drives, moving the module in directions not pointed out by laser emission of photo-detectors prior to moment of their lighting. Automatic closing hatch with screen cleaning assembly of input window of photo-detector is controlled by signals from wheels passage registration indicators.

EFFECT: improved safety of trains movement.
