MASTER CONTROLLER Russian patent published in 2002 - IPC

FIELD: railway transport; train control systems. SUBSTANCE: invention relates to master controller which has two turning angle transmitters putting out signals corresponding to each detent position of control handle coupled with transmitters. The handle can be set in one of the following positions: running at power consumption, neutral and braking. In addition to these transmitters controller is furnished with position transmitter which detents neutral position of handle and provides possibility of checking the signals put out by turning angle transmitters for compliance with neutral position of handle and bringing to zero the signal transmitter which does not confirm neutral position of handle which is actually in neutral position. Master controller of such design has two doubling systems providing possibility of normal control over locomotive even if turning angle transmitter of one system fails to operate which leads to disagreement in output signals of two transmitters. EFFECT: improved reliability of train control. 3 cl, 7 dwg
