METHOD FOR AUTOMATIC DIAGNOSTICS OF SYSTEM WITH ELECTRIC ACTUATOR Russian patent published in 2014 - IPC G05B23/02 

FIELD: measurement equipment.

SUBSTANCE: invention relates to diagnostics of a technical state of systems with an electric actuator. The invention proposes a method for automatic diagnostics of a system with an electric actuator, which includes a control device connected via communication channels to the electric actuator containing a control unit and an electric motor based on subsequent supply of test signals; with that, the system is changed over to a diagnostic mode; with that, first, information communication channels of the control unit are diagnosed by supply of test signals from outputs of the control unit to inputs of the control device and by analysing by means of the control device the received test signals at their inputs; with that, those information communication channels of the control unit are considered to be serviceable through which all test signals have passed within the specified period of time and in the specified sequence; then, provided that information communication channels of the control unit are considered to be serviceable, control communication channels of the control unit are diagnosed by supplying test signals from the outputs of the control device to the inputs of the control unit by analysing by means of the control unit the received test signals at their inputs; with that, those control communication channels of the control unit are considered to be serviceable through which all test signals have passed during the specified period of time and in the specified sequence, and the diagnostic mode is finished.

EFFECT: control of a technical state of a control system of an electric actuator.
