COMMAND INPUT DEVICE Russian patent published in 2019 - IPC B61C17/12 H01H19/60 G05G1/04 

FIELD: engineering; control systems.

SUBSTANCE: invention relates to a control device for locomotives. Command input device contains two actuators, each of which is equipped with a disk with a handle, a mechanism for fixing the positions of the handle with a spring-loaded roller and recesses for the roller. Additionally, the device contains a self-return mechanism with a torsion spring, a holder of two magnets mounted on the rotary axis of the handle, three channels of contactless angle sensors, where each channel consists of a chip using Hall sensors and a magnet. Microchips with Hall sensors are placed on the boards of the angle sensors and integrated into a three-channel block of angle sensors. All three channels of the angle sensors of each drive are connected to one common controller module board, which consists of three controller channels with their own power sources, a majoritarian scheme in two out of three states, electronic command generation keys.

EFFECT: technical result is to increase the reliability and increase the service life of the command input device.
