Structural Analysis And Control Study Of A Large Carriage Type Lift-and-Shift Intelligent Three-Dimensional Garage

With the rising number of cars in China,the shortage of parking spaces in the city is gradually increasing,and the construction of three-dimensional parking garage has become an important way to solve the problem.In this paper,a hybrid car-type lift and shift intelligent garage is designed on the basis of vertical lift and flat mobile garage,and its structure and control system are analysed and studied.Firstly,the structure of the large carriage lift and shift type intelligent garage is analysed and its structural components and working principles are introduced.Based on the characteristics of the steel frame,the deformation and stresses of the steel frame under different working conditions are analysed using ANSYS software to verify its safety.Secondly,the access scheduling strategy is analysed based on the working characteristics of the large car-type lift-and-shift type intelligent three-dimensional garage,combined with the queuing theory.Using the access time as the objective function,the mathematical models of three strategies,namely storage priority,in-situ waiting and cross-access,are established,and the access efficiency of the three access strategies is simulated by MATLAB under peak storage,peak pick-up and comparable access scenarios to obtain the best access strategy.Again,the garage control system is studied based on edge computing and intelligent gateway,and a stereo garage control system with ARM+DSP controller as the core is designed.At the same time,based on the data processing capability of the system at the equipment side,a neural network model is combined to achieve the classification of users of the stereo garage.Finally,a semi-physical model of a large carriage lift-and-shift type intelligent stereo garage is built to test the control system and verify the rationality of the access strategy.The resulting edge computing-based garage system can be used as a basis for the future marketing of the garage and as a technical reference for future applications of the garage in smart city systems.
