Power control device for home appliances
First Claim
1. A communication device for transmitting and receiving data to and from a communication terminal device by transmitting a signal during a transmission period for establishing transmission and reception of the data to the communication terminal device when the communication terminal device, which alternately switches between an active state and a sleep state, is switched to the active state, the active state being triggered by receipt of the signal and is a state in which communication is possible, and the sleep state being a state in which communication is not possible, the communication device comprising:
- a power saving control unit configured to control the transmission period used for transmitting the signal used for switching the communication terminal device from the sleep state to the active state in such a manner that the transmission period during which the signal is transmitted is increased as a power value difference increases, the power value difference being a value obtained by subtracting a total power consumption value of a power consumption appliance including the communication terminal device from an available power supply value for power available to the power consumption appliance; and
a communication interface unit configured to transmit the signal containing information indicating the transmission period to the communication terminal device so as to set the communication terminal device in the active state with a period according to the transmission period determined by the power saving control unit.

Abstract
An energy controller, as a communication device, transmits and receives data by transmitting a signal for establishing transmission and reception of the data to network-connected home appliances. The energy controller includes a power saving control unit that determines a transmission period such that the transmission period during which the signal is transmitted is increased as a power value difference increases, which is a value obtained by subtracting the total power consumption value of a power consumption appliance from available power supply value to the power consumption appliance including the network-connected home appliances; and a wireless communication IF for transmitting the signal containing the information indicating the transmission period to the network-connected home appliances in order to set the network-connected home appliances in an active state with a period according to the transmission period.
