Introduction

GB/T 41782 "Internet of Things System Interoperability" aims to specify the Internet of Things system interoperability framework, network connectivity, data semantics, the requirements of syntax and entity behavior make the Internet of Things system more widely used. GB/T 41782 is planned to consist of five parts.

constitute.

--- Part 1: Framework. The purpose is to guide the design of a framework for the interaction between IoT systems and their internal entities.

--- Part 2: Network connectivity. The purpose is to guide the internal network of the Internet of Things system and the different networks of the Internet of Things system.

interoperability and interconnection.

--- Part 3: Semantic interoperability. The purpose is to specify the interoperability requirements for implementing data semantics in IoT systems.

--- Part 4: Syntax interoperability. The purpose is to specify the interoperability requirements for data syntax in IoT systems.

--- Part 5: Behavioral interoperability. The purpose is to guide the behavioral specifications of entities in interoperable systems of the Internet of Things.
