  • Abstract ( 32 ) HTML( 18 )   
  • With the continuous advancement of digital transformation throughout society, it has become a trend to use cloud computing, edge computing, artificial intelligence, big data, and the Internet of Things to empower various types of new smart parks. However, due to the large space occupation, the large number of settled units, and the long continuous construction period, many parks have problems in information system construction, such as redundant construction, information isolated island, complex network architecture, insufficient quantities of computing power, and the absence and shortage of a unified computing power scheduling system. Meanwhile, with the deepening application of various high-computing-demand technologies, the absence and shortage of a unified computing power scheduling system may become a fundamental issue restricting the digital transformation of a park. This paper studies the application of cloud-edge-device integrated computing network architecture in smart parks, from the dimensions of the current situation of computing networks, the computing network architecture of cloud-edge-device, and specific cases of integrated computing network architecture in smart parks.

  • Abstract ( 33 ) HTML( 16 )   
  • The standard digitization is a transformative development direction from textual form to data form, and it is also an inevitable trend in the digital transformation and development of the world today. As the academic community has not had a unified view on the key issues, core challenges, and countermeasures of standard digitization, the concepts and requirements of standard digitization have been sorted out, and 7 development needs, 4 practical logics, and 11 core challenges have been proposed. Suggestions for empowering national standardization development with standard digitization have also been proposed. The results show that standard digitization is an engineering problem, and it is necessary to judge whether it is necessary to carry out digital transformation of standards based on the actual situation. Besides, it is necessary to pay attention to data security and personal privacy protection. It is important to realize that standard digitization involves resilience across numerous industrial chains. It is necessary to promote the development of machine readable standards based on both stock standards and incremental standards.
