The invention discloses an intelligent stereo garage system based on the Internet of Things. The intelligent stereo garage system comprises a vehicle detection module, a service timing module, a guide lamp module, a garage lifting module, an adjusting steering module, a positioning module, a conveying belt, a parking prompt module, a regulation and control center, an information feedback module, a long-term parking layer and a temporary parking layer. According to the intelligent stereo garage system based on the Internet of Things, the intelligent stereo garage system is in a fan-shaped design, the garage only needs to ascend and descend, compared with a traditional cube-shaped garage, and vehicle bodies are inconvenient to take out, the vehicle bodies do not interfere with one another, vehicles can be well parked, the self-running efficiency of the garage is improved, and the practicability is high. And a conveying belt in the garage lifting module has the same operation effect, parked vehicles can be well helped to be rapidly taken out and parked, the use effect can be further improved, the long-term storage layer and the temporary storage layer are located in the transverse direction and the vertical direction, and the vehicles can be more conveniently and accurately parked.
