The Design And Implementation Of Virtual Meter Based On IEC62056

The thesis aims to realize the virtual meter working in the environment of IEC 62056.First it put forward the metering model which is compliance of IEC 62056, then give the detailed analysis on the most important parts, like metering console, metering server, telecommunication subsystem and memory subsystem which form the infrastructure. Based on those, Demand analysis of virtual meter is made, so as to clarify and manage the function demard, no-function demard and design trstriction, and even more, point out that use HDLC-based DLMS protocol stack in which COSEM application layer is common as an optional instance of protocol, and realize the virtual meter which is compliance of IEC62056, and DLMS protocol which is seperatly packaged.At last, the test on phisical layer, HDLC layer and application layer are performed. The test and real application show that the virtual meter designed in this paper can satisfy all the requirements of project.
