Design of Internet of Things Training Platform Integrating Multi-source Perception and Digital Transmission

Aiming at the problems existing in current Internet of Things (IoT) practical teaching, such as single equipment function, separated technical links, and disconnection from real industrial applications, a set of IoT teaching and training platform integrating multi-source perception and digital transmission is designed. At the hardware level, the platform integrates a variety of sensors and digital communication modules. At the software level, a system scheme based on the three-layer architecture of "perception-network-application" is designed, and interfaces for cloud platform and mobile applications are installed in the application layer. The overall design has clear structure, distinct modules, complete functions and high flexibility. It is intended to provide students with a full-chain and project-based training environment from data collection, transmission to processing, so as to effectively cultivate their comprehensive application ability of digital technology and system integration ability.
