DEVICE FOR SWITCHING INPUT ANALOGUE SIGNALS OF DRILLING EQUIPMENT Russian patent published in 2019 - IPC G06F9/50 G05B19/42 

FIELD: physics.

SUBSTANCE: invention relates to control of production process. Device for switching input analogue signals of drilling equipment comprises controller consisting of controller module, input module and output discrete signals module, input module and output analogue signals module. There are also commanders on the driller console. In case of failure of input analogue signals module, it is taken out of operation, and functions of receiving analogue signals for setting rotation frequency of drilling winches and rotor are transmitted to control system of thyristor converters. Device is additionally equipped with an actuating unit for commutation of switches providing for removal of the damaged module of input analogue signals from the operation and supply of analogue signals for setting rotation frequency of the drill winch and the rotor to control systems of thyristor converters. Control systems of thyristor converters include terminals for receiving analogue signals and a signal is generated for an actuating unit and switching switches.

EFFECT: improving operating reliability.
