Abstract

Provided are an AMI gateway apparatus and method for processing large AMI data and an application profile. The AMI gateway apparatus and method are associated with collecting meter data of smart meters measuring the amount of electricity or the like and transmitting the meter data to an AMI server. Disclosed is a method of reducing an ID type and a method of minimizing meter data to reduce the transmission rate of large AMI data including an ID value and meter data. A method of setting a gateway ID value according to locations and zones is also provided. Those three methods achieve the efficient transmission of large AMI data to an AMI server and is applicable to various gateway apparatuses processing various application profiles such as an HA profile controlling and sensing home appliances, an SE profile providing an AMI service, a TA profile providing mobile services or the like.

Claims

1. An Advanced Metering Infrastructure (AMI) gateway apparatus comprising:

a storage storing a second Identification (ID) value as a mapping table, the second ID value having a smaller data size than a first ID value, which identifies a meter, and mapped with the first ID value;

an ID data processing unit converting the first ID value into the second ID value on the basis of the mapping table;

a meter data processing unit calculating an increase in the meter value receiving from the meter; and

a processor receiving the second ID value and the increase in the meter value and transmitting the received second ID value and the increase in the meter value to an AMI server.

2. The AMI gateway apparatus of claim 1, wherein the ID data processing unit transmits only the lowest bytes of a Media Access Control (MAC) address included in the first ID value to the processor.

3. The AMI gateway apparatus of claim 2, wherein the lowest bytes are more than 2 bytes.

4. The AMI gateway apparatus of claim 1, wherein the ID data processing unit converts the first ID value into the second ID value of the minimum bytes mapped with the first ID value by using the mapping table, and transmitting the second ID value to the processor.

5. The AMI gateway apparatus of claim 1, wherein the ID data processing unit converts the first ID value into a string or a number by using the mapping table, and transmitting the converted string or number to the processor as the second ID value.

6. The AMI gateway apparatus of claim 1, further comprising a network controller connected to the processor, processing ZigBee and Power Link Communication (PLC) functions, and connected to an adjacent sensor network.

7. The AMI gateway apparatus of claim 1, further comprising a host controller performing data communication with the AMI server via a wired/wireless Internet Protocol (IP) network,

wherein the processor transmits the second ID value and the increase in the meter value to the AMI server through the host controller.

8. The AMI gateway apparatus of claim 1, further comprising:

a rule input user interface receiving a rule corresponding to a specific service profile according to a cluster, a command and an attribute value related to the specific service profile to receive the specific service profile existing in ZigBee;

a rule ZigBee profile converter converting the rule according to a ZigBee cluster, an attribute and a command;

a rule applier applying the rule, converted according to the ZigBee cluster, the attribute and the command, to a gateway; and

an application profile applier including a function of the rule applier and communicating with the processor.

9. The AMI gateway apparatus of claim 8, wherein the ZigBee service profile is a smart energy profile, a Home Automation (HA) profile or a Telecom Application (TA) profile.

10. An Advanced Metering Infrastructure (AMI) gateway apparatus comprising:

a storage storing a second Identification (ID) value and zone information corresponding to a gateway ID, the second ID value having a smaller data size than a first ID value, which identifies a meter, and mapped with the first ID value;

an ID value processing unit converting the first ID value into the second ID Value by using the mapping table, and classifying the converted second ID value according to the zone information;

a meter value processing unit calculating an increase in the meter value according to the zone information; and

a processor processing various control messages and transmitting the second ID value and the increase in the meter value to an AMI server as large AMI data.
