CONTROL DEVICE, POWER USAGE CONTROL SYSTEM AND CONTROL METHOD
First Claim
1. A control device controlling an operation of each of a plurality of devices connected to house wiring, said control device comprising:
- a storage device storing reference power, device priority information showing a control priority representing a degree for determining a control order of said plurality of devices and room priority information showing a priority of each room in which said plurality of devices are disposed;
an acquisition unit acquiring power usage of said plurality of devices;
a changing unit changing said control priority based on said room priority information;
a determination unit determining whether or not said acquired power usage has exceeded said reference power; and
a transmitting unit transmitting, to a device of said plurality of devices that is relatively high in said control priority after change, an instruction to reduce the power usage of the device, based on determination that said acquired power usage has exceeded said reference power.

9. A power usage control system including a control device controlling an operation of each of a plurality of devices connected to house wiring, and the plurality of devices,
said control device comprising: -
a storage device storing reference power, device priority information showing a control priority representing a degree for determining a control order of said plurality of devices, and room priority information showing a priority of each room in which said plurality of devices are disposed; an acquisition unit acquiring power usage of said plurality of devices; a changing unit changing said control priority based on said room priority information; a determination unit determining whether or not said acquired power usage has exceeded said reference power; and a transmitting unit transmitting, to a device of said plurality of devices that is relatively high in said control priority after change, an instruction to reduce the power usage of the device, based on determination that said acquired power usage has exceeded said reference power, in response to reception of said instruction, said plurality of devices each performing an operation based on said instruction.

10. A control method for a control device for controlling an operation of each of a plurality of devices connected to house wiring, said control method comprising the steps of:
-
a processor of said control device storing, in a memory of said control device, reference power, device priority information showing a control priority representing a degree for determining a control order of said plurality of devices and room priority information showing a priority of each room in which said plurality of devices are disposed; said processor acquiring power usage of said plurality of devices; said processor changing said control priority based on said room priority information; said processor determining whether or not said acquired power usage has exceeded said reference power; and said processor transmitting, to a device of said plurality of devices that is relatively high in said control priority after change, an instruction to reduce the power usage of the device, based on determination that said acquired power usage has exceeded said reference power.
