IEC 62056的本部分规定了对象识别系统（OBIS）的总体结构，以及计量设备中所有常用数据项到其识别码的映射。 OBIS为计量设备内的所有数据提供唯一标识符，不仅包括测量值，还包括用于配置或获取计量设备行为信息的抽象值。本文件中定义的ID代码用于识别: -IEC 62056-6-2:2021中定义的各种IC实例或对象的逻辑名称； -通过通信线路传输的数据； -计量设备上显示的数据，见第A.2条。 本文件适用于所有类型的计量设备，如全集成仪表、模块化仪表、电费附件、数据集中器等。 为了涵盖测量除电力以外的能源类型的计量设备、测量多种能源的组合计量设备或具有多个物理测量通道的计量设备，引入了介质和通道的概念。这允许识别来自不同来源的仪表数据。虽然本文件充分定义了其他介质的识别系统结构，但非电能相关数据项到ID代码的映射是单独完成的。 注EN 13757-1:2014定义了除电以外的计量设备的标识符:热成本分配器、热能、燃气、冷水和热水。

This part of IEC 62056 specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes. OBIS provides a unique identifier for all data within the metering equipment, including not only measurement values, but also abstract values used for configuration or obtaining information about the behaviour of the metering equipment. The ID codes defined in this document are used for the identification of: - logical names of the various instances of the ICs, or objects, as defined in IEC 62056-6-2:2021; - data transmitted through communication lines; - data displayed on the metering equipment, see Clause A.2. This document applies to all types of metering equipment, such as fully integrated meters, modular meters, tariff attachments, data concentrators, etc. To cover metering equipment measuring energy types other than electricity, combined metering equipment measuring more than one type of energy or metering equipment with several physical measurement channels, the concepts of medium and channels are introduced. This allows meter data originating from different sources to be identified. While this document fully defines the structure of the identification system for other media, the mapping of non-electrical energy related data items to ID codes is completed separately. NOTE EN 13757-1:2014 defines identifiers for metering equipment other than electricity: heat cost allocators, thermal energy, gas, cold water and hot water.
