[0002] With the acceleration of urbanization and the continuous increase in the number of cars, the problem of parking difficulties has become increasingly prominent. As an effective means of efficiently utilizing space and alleviating parking pressure, the stereo garage has received widespread attention and application. As the core component of the stereo garage, the large car device is responsible for carrying and transporting vehicles. The stability and reliability of its control system directly affects the operating efficiency and user experience of the entire stereo garage.

[0003] As the number of vehicles in the garage increases, the amount of data that the wireless communication control system of the large car unit in the stereo garage needs to process simultaneously will also increase accordingly. In addition, multiple large cars need to continuously report their location, status and other information to the central control system while moving. The transmission volume of this data is large, which will also increase the amount of data transmitted. When the amount of data in the network exceeds the network's processing capacity, network congestion will occur, which will cause data transmission delays or losses, thereby affecting real-time and stability. Summary of the invention
