Abstract

There is provided an analysis server including a first verifying unit that analyzes data acquired from a local power management system composed of an electronic appliance provided with a sensor and a power management apparatus managing power supply to the electronic appliance connected to a power network, by using history information of the local power management system or data acquired from another local power management system with a power usage state similar to that of the local power management system, a second verifying unit that analyzes the data acquired from the local power management system, by using an estimated value calculated by simulation using characteristics information and/or specification information of the electronic appliance, and a control unit that controls the first verifying unit and the second verifying unit.

Claims

1. An analysis server comprising:

a first verifying unit that analyzes data acquired from a local power management system composed of an electronic appliance provided with a sensor and a power management apparatus managing power supply to the electronic appliance connected to a power network, by using history information of the local power management system or data acquired from another local power management system with a power usage state similar to that of the local power management system;

a second verifying unit that analyzes the data acquired from the local power management system, by using an estimated value calculated by simulation using characteristics information and/or specification information of the electronic appliance; and

a control unit that controls the first verifying unit and the second verifying unit.

2. The analysis server according to claim 1,

wherein the first verifying unit includes

an operation judging unit that calculates a characterizing amount from the data acquired from the local power management system, and judges an operation of an apparatus within the local power management system based on the calculated characterizing amount,

a database management unit that stores the data acquired from the local power management system as a database, and

a virus definition file management unit that takes, as a virus definition file, a pattern which has been extracted by analyzing a pattern of data for which occurrence of an abnormal operation has been detected by the operation judging unit.

3. The analysis server according to claim 2, wherein the database management unit calculates, based on the data stored in the database, the characterizing amount used by the operation judging unit for judgment, and stores the calculated characterizing amount in a judgment dictionary used by the operation judging unit for judgment.

4. The analysis server according to claim 3,

wherein the data acquired from the local power management system is sensor information relating to a battery provided in the power management apparatus within the local power management system, and

wherein at least one of the first verifying unit and the second verifying unit analyzes the sensor information relating to the battery, and specifies the battery that is to be excluded from the local power management system.

5. The analysis server according to claim 4,

wherein the second verifying unit

calculates an estimated characteristic value of the battery based on the sensor information relating to the battery and electrical specifications of the battery, and

specifies the battery to be excluded according to a degree of discrepancy between the calculated estimated characteristic value and the sensor information.

6. The analysis server according to claim 2,

wherein the first verifying unit transfers to the second verifying unit the data for which occurrence of an abnormal operation has been detected by the operation judging unit, and

wherein the second verifying unit corrects a parameter of the simulation by using the data, for which occurrence of an abnormal operation has been detected, transferred from the first verifying unit.

7. The analysis server according to claim 1, wherein the control unit performs analysis of the data acquired from the local power management system, by using at least one of a verification process by the first verifying unit and a verification process by the second verifying unit.

8. A method of analyzing data, comprising the steps of:

analyzing data acquired from a local power management system composed of an electronic appliance provided with a sensor and a power management apparatus managing power supply to the electronic appliance connected to a power network, by using history information of the local power management system or data acquired from another local power management system with a power usage state similar to that of the local power management system; and

analyzing the data acquired from the local power management system, by using an estimated value calculated by simulation using characteristics information and/or specification information of the electronic appliance,

wherein the data acquired from the local power management system is analyzed by using at least one of the steps.
