In this paper, application layer protocol of C12.22 node, defined by ANSI C12.22 is implemented. ANSI C12.22 defines application layer only among the OSI 7 layers and recommends using the existing protocols for the 1~4 layer to transmit the information. TCP/IP which is one of the generally used protocols has been applied for the transport and network layer protocol in this paper. ANSI C12.19 defines the parameters for the watt-hour meter, and C12.22 application layer defines the network services and data structures networking the watt-hour meter parameters at a minimum. This kind of services and data structures are used for the configuration, programming, monitoring of the networked watt-hour meter or collecting information of the watt-hour meter. A embedded board has been used to implement the C12.22 application layer and a test program for the AMI application server has been developed for the functional test.

In this paper, a smart meter applying the international communication protocols has been developed. A smart meter requires communication protocols for two-way communication and control technology, registration and deregistration of electronic devices between electric power suppliers to exchange data. Standardization for communication protocols of a smart meter has been proceeding both in the US and Europe. The smart meter developed in this paper applied ANSI C12.22 as a communication protocol which is a north american standard. A smart meter should also provide the electric consuming information and electricity charge information to the customer in real time. Thus, the customer can behave the demand response based on this information. In this paper, the measured electricity from the smart meter is reported to the customer, and IHD(In Home Display) implemented with the windows software presents the reported real time data.
