Abstract

There is provided an electronic appliance including a plurality of electrical parts having electrical characteristics that are different thereamong and for each electronic appliance, a characteristics measuring unit that measures the characteristics of at least one electrical part, a switch that switches between the electrical parts whose characteristics are to be measured by the characteristics measuring unit, and a control unit that controls the switch and causes the characteristics measuring unit to measure the characteristics of a predetermined electrical part, and that transmits, to a power management apparatus managing at least power supply to its own electronic appliance, information relating to the characteristics measured by the characteristics measuring unit and an appliance ID of its own electronic appliance.

Claims

1. An electronic appliance comprising:

a plurality of electrical parts having electrical characteristics that are different thereamong and for each electronic appliance;

a characteristics measuring unit that measures the characteristics of at least one electrical part;

a switch that switches between the electrical parts whose characteristics are to be measured by the characteristics measuring unit; and

a control unit that controls the switch and causes the characteristics measuring unit to measure the characteristics of a predetermined electrical part, and that transmits, to a power management apparatus managing at least power supply to its own electronic appliance, information relating to the characteristics measured by the characteristics measuring unit and an appliance ID of its own electronic appliance.

2. The electronic appliance according to claim 1, wherein the electrical characteristics are impedance characteristics of the at least one electrical part or transistor characteristics of a semiconductor device included in the at least one electrical part.

3. The electronic appliance according to claim 2,

wherein, when registering the characteristics of the predetermined electrical part in the power management apparatus, the control unit causes the characteristics measuring unit to measure the characteristics of the predetermined electrical part and transmits, to the power management apparatus, the information relating to the characteristics measured by the characteristics measuring unit and the appliance ID of its own electronic appliance, and

wherein the power management apparatus receives the information relating to the characteristics and the appliance ID transmitted by the control unit and holds the information relating to the characteristics in association with the appliance ID.

4. The electronic appliance according to claim 3,

wherein the power management apparatus

receives the information relating to the characteristics and the appliance ID transmitted by the electronic appliance,

holds, in a case the information relating to the characteristics corresponding to the appliance ID that has been received is not held, the information relating to the characteristics in association with the appliance ID that has been received,

checks, in a case the information relating to the characteristics corresponding to the appliance ID that has been received is held, the information relating to the characteristics that has been received against the information relating to the characteristics that is held, and

permits power supply to the electronic appliance of the appliance ID that has been received in a case both pieces of information match each other according to the check, and prohibits power supply to the electronic appliance of the appliance ID that has been received in a case both pieces of information do not match each other according to the check.

5. The electronic appliance according to claim 4, wherein, in a case of re-registering the information relating to the characteristics, the control unit switches the switch and causes the characteristics measuring unit to measure the characteristics of another electrical part different from the predetermined electrical part, and transmits, to the power management apparatus, the information relating to the characteristics measured by the characteristics measuring unit and the appliance ID of its own electronic appliance.

6. The electronic appliance according to claim 3, wherein, in a case the information relating to the characteristics and the appliance ID transmitted by the electronic appliance are received, the power management apparatus accesses a manufacturer server of the electronic appliance corresponding to the appliance ID that has been received, acquires the information relating to the characteristics corresponding to the electronic appliance from the manufacturer server, and holds the information relating to the characteristics that has been acquired and the appliance ID that has been received in association with each other.

7. A power management apparatus comprising:

a receiving unit that receives information relating to characteristics and an appliance ID from an electronic appliance including a plurality of electrical parts having electrical characteristics that are different thereamong and for each electronic appliance, a characteristics measuring unit that measures the characteristics of at least one electrical part, a switch that switches between the electrical parts whose characteristics are to be measured by the characteristics measuring unit, and a control unit that controls the switch and causes the characteristics measuring unit to measure the characteristics of a predetermined electrical part, and that transmits, to the power management apparatus managing at least power supply to its own electronic appliance, the information relating to the characteristics measured by the characteristics measuring unit and the appliance ID of its own electronic appliance;

a characteristics information holding unit that holds the information relating to the characteristics in association with the appliance ID received by the receiving unit; and

an appliance identifying unit that identifies the electronic appliance by using the information relating to the characteristics held by the characteristics information holding unit.

8. A method of identifying an appliance, comprising the steps of:

controlling a switch, by an electronic appliance including a plurality of electrical parts having electrical characteristics that are different thereamong and for each electronic appliance, a characteristics measuring unit that measures the characteristics of at least one electrical part, and the switch that switches between the electrical parts whose characteristics are to be measured by the characteristics measuring unit, and causing, by the electronic appliance, the characteristics measuring unit to measure the characteristics of a predetermined electrical part, and transmitting, by the electronic appliance, to a power management apparatus managing at least power supply to the electronic appliance, information relating to the characteristics measured by the characteristics measuring unit and an appliance ID of the electronic appliance;

receiving, by the power management apparatus, the information relating to the characteristics and the appliance ID transmitted by the electronic appliance;

holding, by the power management apparatus, the information relating to the characteristics in association with the appliance ID received in the step of receiving; and

identifying, by the power management apparatus, the electronic appliance by using the information relating to the characteristics held in the step of holding.
