Abstract

Provided is a network system including an advanced metering infrastructure, an energy management system, a computer, and a diagnostic program. The advanced metering infrastructure interactively communicates with a power supply source and measures energy from the power supply source. The energy management system is connected to the advanced metering infrastructure to communicate with it and controls an operation of an electric product based on operation information of the electric product or energy information from the power supply source. The computer is connected to the electric product or energy management system to communicate with the electric product or energy management system. The diagnostic program is performed by the energy management system or computer and diagnoses a trouble of the electric product. An electric product having a trouble is remotely diagnosed to provide a quick countermeasure, thereby detecting the cause of the trouble without a service engineer and improving a user'"'"'s convenience.

Claims

1. A network system comprising:

an advanced metering infrastructure interactively communicating with a power supply source and measuring energy supplied from the power supply source;

an energy management system connected to the advanced metering infrastructure to communicate with the advanced metering infrastructure and controlling an operation of an electric product based on information about the operation of the electric product or energy information supplied from the power supply source,

a computer connected to the electric product or the energy management system to communicate with the electric product or the energy management system; and

a diagnostic program that is performed by the energy management system or the computer and diagnoses a trouble of the electric product.

2. The network system according to claim 1, further comprising a service center that is connected to the computer or the energy management system to communicate with the computer or the energy management system and diagnoses an anomaly of the electric product based on operation information of the electric product.

3. The network system according to claim 2, wherein the service center transfers a result of the diagnosing of the anomaly of the electric product or a countermeasure thereof to the computer or the energy management system.

4. The network system according to claim 2, wherein when it is determined that the trouble of the electric product is not removed by the diagnostic program, the service center diagnoses the trouble.

5. The network system according to claim 1, wherein the diagnostic program is provided to the energy management system, the computer, or an internet.

6. The network system according to claim 1, further comprising a memory that is removably installed on the electric product or the computer and stores operation information of the electric product.

7. The network system according to claim 6, wherein when the memory is installed on the computer, the operation information of the electric product is diagnosed by the diagnostic program.

8. The network system according to claim 1, wherein operation information of the electric product is transmitted to the energy management system or the computer, and the transmitted operation information is diagnosed by the diagnostic program.

9. A network system comprising:

an advanced metering infrastructure communicating with a power supply source and measuring energy supplied from the power supply source;

an energy management system connected to the advanced metering infrastructure to communicate with the advanced metering infrastructure and controlling an operation of an electric product based on information about the operation of the electric product or energy information supplied from the power supply source; and

a service center connected to the energy management system to communicate with the energy management system and remotely diagnosing a trouble of the electric product.

10. The network system according to claim 9, further comprising a computer configured to store operation information of the electric product.

11. The network system according to claim 10, further comprising a memory that is removably coupled to the computer and transfers the operation information of the electric product to the computer.

12. The network system according to claim 10, further comprising a diagnostic program using the operation information of the electric product to diagnose a trouble of the electric product, wherein the diagnostic program is stored in one of the energy management system, the computer, and a web page of an internet.

13. A method of controlling a network system, the method comprising:

recognizing an anomaly of an electric product in operation;

primarily diagnosing operation information of the electric product through a diagnostic program;

transmitting the operation information of the electric product to a service center, based on a result of the diagnosing through the diagnostic program; and

secondarily diagnosing the anomaly of the electric product at the service center.

14. The method according to claim 13, wherein the diagnostic program is stored in at least one of an energy management system controlling an operation of the electric product, a computer, and a web page of an internet, and the computer and the web page store the operation information of the electric product.

15. The method according to claim 14, wherein when an anomaly of the electric product is recognized, the operation information of the electric product is transferred to the energy management system, the computer, or the web page through a memory or a set communication method.

16. The method according to claim 13, wherein when a self diagnosis of the electric product is impossible according to the result of the diagnosing through the diagnostic program, the operation information of the electric product is transferred to the service center.
