Title:
FAILURE DETECTION DEVICE, METHOD FOR CONTROLLING FAILURE DETECTION DEVICE, INFORMATION PROCESSING PROGRAM AND RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP2020045924
Kind Code:
A
Abstract:
To detect a failure in an actuator using displacement time of a movable part regardless of a surrounding temperature and a type of the actuator.SOLUTION: A failure detection device executes processing of determining whether a failure is present by using a feature amount (Wand W) that is a value obtained by dividing a value obtained by subtracting the minimum value (Tand T) of actuator's piston movement time from the maximum value (Tand T) by an initial value (Tand T) of the movement time.SELECTED DRAWING: Figure 4
