Research On Intelligent Parking Lot Control System Based On PLC

With the improvement of the economic level of our country,more and more peop le in order to meet the travel convenience and the choice of the purchase of vehicles,However due to urban development and population density increased,the city of idle land more and less,Traditional ground and underground parking field has already cann ot satisfy the increasing vehicle,So "parking difficult" has become a major problem in the city now travel.Intelligent car-park is dedicated to realize all kinds of vehicles of the automatic parking and scientific storage facilities,can make full use of the land resources,make full use of its advantages in the space,maximum limit parking vehicles,become the important way to solve the problem of urban static traffic.At first,this paper analyzes the current development status of domestic and abroad intelligent parking areas and existing problems,Then introduces the main research contents of this paper:(1)Clarify the design scheme,using the PLC as controller,design 3x3 up-down and translation stereo parking lot control system.(2)The research on the parking lot queuing algorithm and access vehicle strategy,the operation indexes of the system are obtained,Which provide sufficient basis for the evaluation and optimization of the operation efficiency.(3)According to intelligent parking field function implementation requirements and takes the applicability and economy principle to determine types of PLC and industrial control computer,and then chooses the motor and motor drive,And describes the system structure and equipment power supply wiring way.The monitoring interface using the SIEMENS S7-200 programming software and King View design and simulation.This paper studies can be realized by hardware and software system car-park intelligence operations,and improving the stability and economy of the parking lot,can effectively solve the problem of urban parking.
