Title:
POWER SUPPLY CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/072399
Kind Code:
A1
Abstract:
This power supply control system is provided with: a current sensor as a first detection unit for detecting a current flowing in each of control apparatuses when each of the control apparatuses is in an operation state; a first current control unit, which is turned on so as to supply a drive current to each of the control apparatuses when each of the control apparatuses is in the operation state, and which is turned off so as to interrupt the drive current supply to each of the control apparatuses on the basis of detection results; a second current control unit, which is turned on so as to supply a dark current to each of the control apparatuses when each of the control apparatuses is in a power saving state, and which is turned off so as to interrupt the dark current supply to each of the control apparatuses when each of the control apparatuses is in the operation state; a dark current sensor as a second detection unit for detecting a voltage reduction quantity when each of the control apparatuses is in the power saving state; and an abnormality determining unit that determines whether there is an abnormality or not in the power saving state of the control apparatuses on the basis of detection results obtained from the second detection unit.
