Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document replaces GB/T 35319-2017 "Internet of Things System Interface Requirements". Compared with GB/T 35319-2017, except for the structural adjustment In addition to the integration and editorial changes, the main technical changes are as follows.

a) Added terms and definitions of interface and external system (see 3.1 and 3.2);

b) Deleted the terms Internet of Things, domain, entity, sensor network, sensing object, basic service system, tag recognition system, and location information Terms and definitions of systems, audio and video information collection systems, and intelligent device interface systems (see 3.1, 3.2, 3.3, 2017 edition) 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10);

c) The figure in the overview was changed (see Chapter 5, Chapter 5 of the 2017 edition);

d) The number of interfaces has been changed (see Chapter 5, Chapter 5 of the 2017 edition);

e) Added basic requirements for interfaces (see Chapter 6);

f) Changed “interface requirements” to “interface transmission content” and changed the content (see Chapter 7, Chapter 6 of the 2017 edition).

5 Overview

This document defines the IoT system interface based on the IoT functional view in GB/T 33474.The IoT system interface is distributed with The interfaces are shown in Figure 1.These interfaces represent the domains connected at both ends (i.e., resource exchange domain, user interaction domain, service provision domain, sensor domain, etc.).

There is a logical association or physical connection between the knowledge control domain and the operation and maintenance management domain), objects (i.e., target objects, users, and external systems).
