PROBLEM TO BE SOLVED: To provide a power supply monitoring device capable of easily detecting abnormality while simplifying a device configuration.SOLUTION: A power supply monitoring device includes: control signal reception means 1; sequence information storage means 2; and comparison means 3. The control signal reception means 1 receives a predetermined control signal that a voltage control device is using for the control of an output voltage from the voltage control device. The sequence information storage means 2 preliminarily stores the sequence information of the predetermined control signal when the voltage control device is normally operating as reference data. The comparison means 3 compares the sequence of the predetermined control signal received by the control signal reception means 1 with the reference data, and determines the presence/absence of the abnormality of the voltage control device as the transmission source of the predetermined control signal.SELECTED DRAWING: Figure 1 |
