Chongqing- The Internet of Things team of Chongqing University of Posts and Telecommunications (CQUPT) Industrial took the lead in formulating two national standards for the Internet of Things (IoT) recently, which also correspond to international standards ISO/IEC21823-2 and ISO/IEC21823-1.
ISO/IEC21823-2 has been adopted by China, the United Kingdom, Canada, Australia, Denmark, and the Netherlands, according to the released National Standards Announcement of the People's Republic of China (No. 13 of 2022).
The IoT is a network based on the Internet, sensor networks, and other information carriers to realize the interconnection of all things.
"At present, the development of IoT is accelerating, but its fragmentation has hindered the development of the entire industry," said Wei Min, deputy dean of the School of Automation, Chongqing University of Posts and Telecommunications.
Like a hundred kinds of mobile phones, there are a hundred kinds of charging interfaces, and users need to buy a hundred kinds of charging cables. This is also a key factor hindering the "Internet of Everything." The two national standards are proposed to solve the Internet interoperability problem, standardizing the IoT's interconnection and interoperability.

The national standard GB/T41782.2-2022 specifies the network connectivity model and the network connectivity requirements between IoT systems and the internal network connectivity requirements.
It aims to solve the specification problem of deploying different networks to realize network interconnection, transmission interface, and interaction between IoT systems.
The GB/T41782.1-2022 national standard describes the interoperability framework of the IoT system composed of various interoperability, and its purpose is to solve the design problem of the interaction between the IoT system and its internal entities. This part of the standard is expected to hold good industrialization significance and economic effect on the IoT, such as smart cities.
For example, in urban construction, the general requirements for interoperability and the national standards in terms of workflow and overall technical requirements are conducive to the effective management of the IoT system and promote the intellectual and digital development of urban construction.
Contributing its strength and wisdom to China's manufacturing power and the Digital China strategy, the Industrial IoT team of CQUPT has also formulated nine other national standards, covering broadband industrial buses, magnetic domain networks, and sensor networks.
