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
GB/T 17215.6XY.

4 Summary
4.1 Basic terms
All communications involve two sets of equipment, denoted by the terms "calling system" and "called system". The caller is the one who decides to originate with the far
A system that communicates with another party system (called the called party). These designations remain in effect throughout the correspondence.
Communication is broken down into a certain number of transactions. Each transaction is represented by a transmission from a sender to a receiver. In these transaction sequences
During this period, the calling party and the called party act as sender and receiver in turn.
The terms "client" and "server" have the same meaning as in the DLMS model (see DL/T 790.441-2004). The server is acting as
The VDE (Virtual Distribution Equipment, see DL/T 790.441-2004) system is used to submit all special service requests, and the client computer is through a
A system in which one or more services request the use of a server for a specific purpose.
The case involving the calling party client and the called party server is undoubtedly the most common case, but based on the calling party server and the called party
Communication with remote clients is also possible, especially for reporting emergency alert events.
4.2 Sublayer and protocol
The described application layer model is subdivided into three sublayers of transport, application and DLMS. The names of each sublayer and protocol are shown in Table 1.
