The Research And Application Of Multistorey Parking Garage Intelligent Control And Optimization Methods

With the rapid development of economy in our country,the surge in car ownership,stereoscopic parking lot more and more get the favour of people.Automated garage made the body with its advantages of convenient operation,safe and reliable,efficient,low consumption,is the attention of domestic and foreign enterprises.However the domestic parking lot of the communication network,the core control technology such as motor control lags behind that of developed countries for a long time,lead to the parking lot core control part localization rate is low.So this article with automatic lifting and moving type stereoscopic parking lot as the research object,the key technology and the control system scheduling algorithm is studied,and design a set of relatively complete stereoscopic parking solution.Combining automated parking lots actual work of research and development projects,on-site parking motor closed-loop control,the fuzzy control theory is applied to three-dimensional parking.According to the fuzzy control theory and motor control accuracy requirements,the paper identifies the motor-dimensional fuzzy controller program and membership functions for the error,the error rate changes and output a fuzzy rule table,fuzzy controller design of the motor,and the motor blur control simulation and compared with traditional control methods.Fuzzy closed-loop control based on the motor small overshoot,fast response,greatly improves the dynamic performance of the system,not only to reduce the impact of inertia when the motor starts and jitter,but also improve car garage access speed,with high practical value.The thesis introduced with constraint-based breadth-first search algorithm as the parking scheduling algorithm,designed a complete lifting and transferring parking solution for the intelligent and highly automated garage,improved resource utilization.Parking spaces occurs when the failure,the vehicle cannot move normally,the target parking spaces cannot successfully import and export arrival,the entire parking operation of the system is not working properly.Thesis on how to use the scheduling algorithm with constraints,to avoid a certain parking spaces or into them,is to let failure parking spaces do not enter the target path of movement among.Meanwhile,the thesis also application process three-dimensional parking and parking in the multi-dimensional breadth-first search algorithm were compared and analyzed in detail,with the constraints of scheduling algorithms in a single-dimensional and multidimensional parking in the parking lot applications are designed and Case Analysis.
