Document Type and Number:
Japanese Patent JP2020125996
Kind Code:
A
Abstract:
To avoid the simultaneous stoppage of a plurality of systems of redundant configuration due to a common cause.SOLUTION: Provided is a control device 1 for controlling a device to be controlled and having a first system and a second system which is redundant to the first system. The control device 1 comprises: a first abnormality detection unit 120 for detecting the abnormality of a first-system circuit 110 constituting the first system; and a second abnormality detection unit 220 for detecting the abnormality of a second-system circuit 210 constituting the second system. The first abnormality detection unit compares the detection value of a first prescribed portion (e.g., a PA1) of the first-system circuit with a first threshold and thereby detects the presence of abnormality in the first-system circuit. The second abnormality detection unit compares the detection value of a second prescribed portion (a PA2) of the second-system circuit, which is a portion equivalent to the first prescribed position, with a second threshold different from the first threshold and thereby detects the presence of abnormality in the second-system circuit.SELECTED DRAWING: Figure 1
