Abstract: Intelligent internet of things (IoT) system simulation is beneficial to the design and implementation of IoT systems.This simulation test adopted high-level Packet Tracer virtualization simulation software, and designed a system simulation model with intelligent perception, intelligent transmission and intelligent control functions,as well as a system control model with intelligent judgment,and introduced dynamic environment management.Then,through Python logic programming it realized the process simulation of the intelligent IoT in the perception layer,transmission layer and application layer.The simulation results showed that the IoT system obtained the environmental factors and the status of the execution device every 1 s,which were consistent with the test results of the control terminal equipment.Based on the control model,the IoT system could intelligently or manually control the state of the actuator through the remote terminal and the cloud server,and could adjust the environmental factors in real time.In the simulation,there was a many-to-many relationship in the impact of the execution device on the environmental factors. The simulation test achieved the purpose of the research.
