Design And Research Of Intelligent Stereo Garage Control System

With the increasing number of cars,the demand for parking spaces is increasing.Intelligent stereo garages can effectively improve space utilization and save more land.There are many stereo garages on the market,but the overall usage is not very good.Most of the current stereo garages have many problems such as high equipment maintenance costs,chaotic garage system management,and poor user experience.Relevant scholars and engineers are constantly designing and researching the control system of stereo garage in response to the above problems.Based on the key areas of current research,combined with the needs of actual stereo garages,this thesis studies stereo garage control system based on rolling optimization.At the same time,in order to improve the management and operation efficiency of the garage system,the garage scheduling strategy based on user behavior is studied.The functional structure of the stereo garage equipment was studied.Firstly,it analyzes the existing problems of the current stereo garage equipment,and chooses a vertical lift stereo garage for design.This type of garage is a larger stereo garage equipment and is one of the stereo garage equipment with the highest space utilization.Based on the characteristics of the vertical lifting stereo garage,this thesis carried out some structural innovations,and designed a hexahedral stereo garage equipment.Aiming at the complex structure of this type of equipment,the overall planning and design of the garage system was carried out using distributed control for easy management and maintenance.Secondly,in view of the chaotic management of large garages and the low operating efficiency,especially the long time of picking up the vertical lift stereo garage,this thesis proposes a series of improved optimization strategies.The efficient management of garage starts with the rational management of garage system data.Thegarage information is classified and different management rights are assigned.Considering the difference in the length of user’s reserved parking time,a fuzzy controller based on the parking time is established to allow reasonable parking space allocation for parked vehicles,to improve the efficiency of the garage.On this basis,when users experience parking overtime,this thesis designs a parking space readjustment strategy.According to the length of user’s overtime,parking space in the garage is readjusted during free time of the garage to shorten time for users to pick up the car.The simulation experiments on fuzzy decision maker in Simulink show that the algorithm can reasonably plan the parking spaces and readjust the overtime vehicles to achieve the effect of improving the overall operating efficiency of the garage.Thirdly,the control strategy of garage platform is studied.Garage transport platforms need to ensure stable and accurate platform operation for a long time under complex and variable loads.This requires the use of more reasonable control algorithms.Based on the stepper motor,this thesis designs a closed loop feedback controller based on rolling optimization.According to the characteristics of the number and frequency of pulses received by stepping motor determine the rotation angle and the speed.Combined with actual garage transportation system,a system model is established and used as a prediction model.After that,feedback correction is continuously performed in the rolling time domain,and the garage transportation platform is guided to track the desired speed trajectory,thereby realizing the motion control of the garage system.The simulation in Matlab and semi-physical model experiments have verified the practicability and advancedness of the algorithm.Finally,in order to verify the practicability of the above design content,a semi-physical model was made.When making an intelligent three-dimensional garage model,the entire control system was established according to the overall design of the previous design,and the main functions of the garage were physically verified.In terms of the carrying system,the system uses a certain stepping motor as the power source,which saves costs and controls more accurately.For the vertical movement,horizontal rotation and horizontal telescopic movement of the carrying platform,the platform lifting mechanism,Platform rotation mechanism and telescoping mechanism were designed.The structure design of this carrying system is reasonable and fully meets the actual needs of the garage model.In terms of intelligent systems,C ++ was used to write the MFC interface,and the human-computer interface was designed.Using radiofrequency technology,a vehicle identification system was built.An intelligent parking space selection and rescheduling system was subsequently designed.In terms of control system,on the basis of distribution,in addition to carrying other subsystems,the main controller of the stereo garage is also designed.For the actual needs of garage system,STM32 chip was selected as the main control chip.At the same time,the peripheral equipment was also designed,and the communication methods were mainly researched.Finally,it was decided to use CAN communication as the main,serial communication as the supplement,and cooperate with WIFI to realize the communication of the garage system.The above-designed functions run normally on the garage model and have a greater guiding effect on the actual stereo garage.This article analyzes the current status of the three-dimensional garage,focuses on the operational efficiency,intelligent management,and motion control of the garage system,and makes a semi-physical model for functional verification,which further improves the intelligence and operational stability of the garage system.The development of the stereoscopic garage has strong practical significance.
