Research And Design Of The Control System Of The 3-Dimensional Lifting And Transversing Garage Based On CPLD

With the rapid development of China’s economy,the national income level continues to increase,and people’s living standards are constantly improving,which makes more motor vehicles enter tens of millions of families.The increasing number of cars in China has also made parking a difficulty in urban management and development today.The three-dimensional parking garage is under rapid development in recent years.It is an effective solution to parking difficulties in urban residential areas and shopping malls.It can effectively use limited land resources to store more vehicles to the maximum extent.A sixstory,two-row,seven-seat,three-story parking garage is taken as the research object in this thesis.Based on in-depth analysis of the working principle and control system structure of the three-story parking garage,a complex programmable logic device(CPLD)is used as the core processor of the parking garage control system.Software and hardware of the threedimensional parking garage control system is studied and designed.Contents of this thesis are as follows:1.Taking the six-story,seven-car parking space ascending and descending type threedimensional parking garage as a model,system components of the entire three-dimensional parking garage control system and its operating principle are studied in detail.2.Hardware design of the three-dimensional parking garage control system is completed and introduced,which includes selection of the CPLD processor,analysis of the peripheral input and output signals of the control system,and design of the main circuit modules of the CPLD controller,including the power supply module,the JTAG download port module,and signal isolation design of circuit module and relay drive module.3.Design of the software program of the parking garage control system is done and introduced,which includes the control principle of the parking inventory pickup,analysis of manual control and automatic control process,and control algorithm design.4.In order to verify the feasibility of the control system plan of the three-dimensional lifting and lateral moving parking garage and the correctness of the control algorithm designed,a simulation debugging platform for the parking garage control system is established.The rationality and correctness of the design are verified through simulation and experiment debugging.At the same time,it also proved the feasibility of the scheme design of the parking garage control system through on-site debugging.An intelligent model of the three-dimensional parking garage control system is established through research and design of the three-dimensional lifting and lateral moving parking garage control system.This model can achieve accurate,stable,and reliable access to the parking spaces.This type of three-dimensional parking garage has the advantages of less floor space and simple structure.It can be expanded according to the on-site land resources to effectively solve parking difficulties in residential areas and shopping malls.
