The operation and maintenance mechanism of smart classrooms in universities based on the cloud-edge-end architecture of the Internet of Things

The Internet of Things technology has improved the accessibility and efficiency of educational resources while promoting innovation and the development of educational models. The Internet of Things technology has been widely applied in the operation and maintenance of smart classrooms in universities. However, the existing operation and maintenance mechanism of smart classrooms based on the Internet of Things technology have some problems such as insufficient system planning, stacking of intelligent devices, poor adaptability to technological iteration and updates, low efficiency in fault handling, and high complexity in operation and maintenance. Therefore, we proposed a cloud-edge-end architecture based on the Internet of Things and developed a digital twin visualization platform for the operation and maintenance of smart classrooms in universities. We offered integrated solutions for the supervision, testing, use, and service of intelligent devices and information systems, and provided a new approach for the operation and maintenance of smart classrooms in universities.
