Research and application of HMI terminal for tobacco primary processing line based on cloud computing environment

This study focuses on the problems of hardware failure, complex maintenance and data security risk in tobacco primary processing HMI terminal centralized control system. This paper presents an HMI terminal solution based on cloud computing and simplified client. The system consists of three core layers: infrastructure, virtualization management, and terminal user layer. By introducing a desktop cloud architecture and multi-replica storage technology, this solution realizes centralized management of computing resources, rapid fault recovery and enhanced data security of HMI terminals. The practical application in Wuhu Cigarette Factory shows that the solution has excellent performance in software compatibility, system performance and fault recovery capabilities. The HMI terminal fault recovery time is reduced from 160 minutes to 12 minutes.
