POWER SUPPLY CONTROL SYSTEM

摘要

A power supply control system includes: a current sensor as a first detector detecting current flowing in each controller in an operating state of each controller; a first current controller turned on to supply a driving current to each controller in the operating state of each controller and turned off to disconnect the driving current supply to each controller based on a determination result; a second current controller turned on to supply a dark current to each controller in a power-saving state of each controller and turned off to disconnect the dark current supply to each controller in the operation state of each controller; a dark current sensor as a second detector detecting a voltage drop amount in the power-saving state of each controller; and an anomaly determinator determining existence of anomaly in the power-saving state of each controller based on a detection result obtained from the second detector.

1. A power supply control system, comprising:
a predetermined number of controllers which can transfer between an operating state in which operations performed by a plurality of electronicses are respectively controlled and a power-saving state in which control of the electronicses is suspended according to a predetermined condition; a monitoring controller for respectively monitoring and controlling current supplied to each of the controllers; a first detector which detects current that flows in each of the controllers in the operating state of each of the controllers; a first current controller which, by controlling of the monitoring controller, supplies a driving current to each of the controllers in the operating state of each of the controllers, and when current that exceeds a predetermined threshold value is detected at the first detector, disconnects the driving current supply to each of the controllers; a second current controller which, by controlling of the monitoring controller, supplies a dark current to each of the controllers by being switched from the first current controller in the power-saving state of each of the controllers, and disconnects the dark current supply to each of the controllers in the operating state of each of the controllers; a second detector which detects a voltage drop amount based on change of the dark current in the power-saving state of each of the controllers; and an anomaly determinator which determines existence of anomaly in the power-saving state of the controllers based on whether or not a predetermined voltage drop amount has been detected by the second detector.
