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
【課題】冗長化された複数の系が共通原因により同時に停止することを回避する。【解決手段】第1の系および第1の系に対する冗長系である第2の系を有し、被制御装置を制御する制御装置1であって、第1の系を構成する第1系統回路110の異常を検出する第1異常検出部120と、第2の系を構成する第2系統回路210の異常を検出する第2異常検出部220と、を備え、第1異常検出部は、第1系統回路の第1所定部位(PA1等)の検出値と第1閾値とを比較することにより第1系統回路の異常の有無を検出し、第2異常検出部は、第2系統回路において第1所定部位に相当する部位である第2所定部位(PA2)の検出値と第1閾値とは異なる第2閾値とを比較することにより第2系統回路の異常の有無を検出する制御装置1を提供する。【選択図】図1
