同样采用ISO/IEC 21823 1:2019，其中概述了适用于物联网系统的互操作性，以及物联网系统互操作性框架。它使物联网系统能够以这样一种方式构建，即物联网系统的实体能够以高效的方式交换信息和相互使用信息，以及独立物联网系统之间的对等互操作性。关键词:互操作性；物联网；系统框架。

Identically adopts ISO/IEC 21823 1:2019, which provides an overview of interoperability as it applies to IoT systems and a framework for interoperability for IoT systems. It enables IoT systems to be built in such a way that the entities of the IoT system are able to exchange information and mutually use the information in an efficient way and peer-to-peer interoperability between separate IoT systems. KEYWORDS: Interoperability; Internet of Things; System framework.
