Introduction

At present, energy conservation, emission reduction, low-carbon, environmental protection and the establishment of a sustainable society have become a global consensus. Countries are actively building regional energy

management system to promote the efficient and scientific use of energy. On this basis, IEC /TC57, TC13 and EN/TC294 jointly established

DLMS/COSEM energy measurement system transmission protocol, in which the electric energy part is defined by IEC 62056 "Electrical measurement data exchange DLMS/

COSEM Components" was completed, and the non-electric part was completed by EN13757 "Instrument Communication System". In order to establish a global unified and open interoperability

As a result, countries around the world have successively transformed IEC 62056 into their own national standards. my country converts IEC 62056-XY into

communication configuration standard.

This communication configuration standard specifies how the COSEM data model and DLMS/COSEM application layer can be

used on the body-specific protocol layer.

The specification of the communication configuration follows the rules specified in Appendix A of IEC 62056-5-3.2016.

The main driving force behind the introduction of smart metering is to provide consumers with appropriate metering information to optimize energy consumption and/or production. for

Therefore, smart meters are equipped with local interfaces to provide billing data to consumers.
