Communication device, power management system having communication device and control method of communication device
First Claim
1. A communication device comprising:
- an acquisition unit configured to acquire an electrical quantity consumed by a power load from the power load;
a communication unit configured to wirelessly transmit a packet including the electrical quantity to a master unit which wirelessly transmits control signals that control electrical quantities consumed by a plurality of power loads; and
a controller configured to switch an operation of the communication unit from a first mode, in which the packet is wirelessly transmitted to the master unit by specifying a destination, to a second mode, in which the packet is wirelessly transmitted without specifying a destination, when the electrical quantity, consumed by the power load and acquired during the first mode, is equal to or greater than a first reference value,wherein the controller switches the operation of the communication unit, even if the acquired electrical quantity is equal to or greater than the first reference value, to a third mode, in which the packet is wirelessly transmitted at a frequency lower than that in the second mode and equal to or greater than that in the first mode and with a transmission power equal to or smaller than that in the second mode, when a packet wirelessly transmitted by another communication device through broadcast is received.

Abstract
Provided is a communication device including an acquisition unit configured to acquire the electrical quantity of a power load, a communication unit configured to wirelessly transmit a packet including the electrical quantity acquired to a master unit that wirelessly transmits a control signal that controls the electrical quantity of a plurality of loads, and a controller configured to switch operation of the communication unit to a second mode in which the packet is wirelessly transmitted without specifying a destination when the electrical quantity equal to or greater than a first reference value is acquired during operation of the communication unit in a first mode in which the packet is wirelessly transmitted to the base station by specifying a destination.

9. A control method of a communication device of a power management system that manages electrical quantity consumed by a power load, the method including:
-
wirelessly transmitting, to a master unit which wirelessly transmits control signals that control electrical quantities consumed by a plurality of power loads, a packet including an electrical quantity consumed by a power load; a first mode in which the packet is wirelessly transmitted to the master unit by specifying a destination; a second mode in which the packet is wirelessly transmitted without specifying a destination; and a control step for switching from the first mode to the second mode when the electrical quantity, consumed by the power load and acquired during the first mode, is equal to or greater than a reference value, wherein in the control step, even if the acquired electrical quantity is equal to or greater than the first reference value, when a packet wirelessly transmitted by another communication device through broadcast is received, the operation of the communication device is switched to a third mode in which the packet is wirelessly transmitted at a frequency lower than that in a second mode and equal to or greater than that in the first mode and with a transmission power equal to or smaller than that in the second mode. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A power management system comprising:
-
a communication device configured to communicate wirelessly with a master unit and manage an electrical quantity consumed by a power load; wherein the master unit wirelessly transmits control signals that control electrical quantities consumed by a plurality of power loads; and wherein the communication device comprises an acquisition unit configured to acquire an electrical quantity consumed by the power load, a communication unit configured to wirelessly transmit a packet including the acquired electrical quantity, and a controller configured to switch an operation of the communication unit from a first mode, in which the packet is wirelessly transmitted to the master unit by specifying a destination, to a second mode, in which the packet is wirelessly transmitted without specifying a destination, when the electrical quantity, consumed by the power load and acquired during the first mode, is equal to or greater than a first reference value, wherein the controller switches the operation of the communication unit, even if the acquired electrical quantity is equal to or greater than the first reference value, to a third mode, in which the packet is wirelessly transmitted at a frequency lower than that in the second mode and equal to or greater than that in the first mode and with a transmission power equal to or smaller than that in the second mode, when a packet wirelessly transmitted by another communication device through broadcast is received. - View Dependent Claims (18)
