Description

A kind of smart city cloud computing parking management information system
Technical field
The present invention relates to parking management system technical field, specially a kind of smart city cloud computing parking management information system System.
Background technology
Many parking lots domestic at present use traditional labor management or combine the semi-automatic manager of IC-card Formula, the i.e. entrance and exit in parking lot are equipped with staff, manually control vehicles while passing, after parking position has been expired, The label of Occupied is then placed in porch.This way to manage not only inefficiency, user's turnover parking lot will stop Wait, and user has to drive at Entrance just learn the full state of parking stall sky.If parking stall is entirely occupied, use Parking lot is found at family again again, and this easily causes traffic jam, and user can not also predict the position in parking lot in advance.With Family both wastes the time during parking stall is found, and because the waste gas of discharge exacerbates air pollution.In traffic peak Phase finds the vehicle of parking stall and queued up when waiting and entering parking lot to outside garage road, also influences traffic unobstructed, and easily induce Traffic accident.And full automatic way to manage is with electronic tag automatic identification vehicle and charged, whole docking process is Automatically, user's turnover parking lot need not be stopped.Although this saves manpower, user needs to install the parking lot in advance The electronic tag that can be recognized, and bind the bank card of oneself and could use, it can only be mounted with identification electricity which has limited user Automatic stopping is realized in the parking lot of subtab equipment, parking difficulty problem still can be met with other parking lots.So this side Formula typically understands large-scale application in some region, the intelligent parking total management system that such as Wuhan City is now just being used.This mode Early investment is higher, and user stills need to after parking lot just know the full situation of parking stall sky, it is impossible to which active obtaining purpose is stopped The parking stall situation of field.There are some parking lots to improve parking stall management efficiency, electronic induction screen is set in Entrance, The empty parking space quantity that one piece of dynamic electron display screen shows parking lot is established at entrance or crossing.Although this is higher than manual type Imitate, but this induced screen can only be fixed and is built up in around parking lot, and car owner, which has to electrical screen, can just see.User Obtain parking space information still relatively more passive.The fact that except current parking stall shortage, parking contradiction also resides in many parking stalls In nobody shows any interest in the awkward state not high with utilization rate.For example:Some parking locations are more inclined, parking stall resource-sharing information Be difficult to obtain, it is known that user it is few, parking lot utilization rate is low;Also some parking lots due to parking price it is higher and Storing cycle is inconvenient and causes the problem of utilization rate is low.Furthermore, existing managing system of car parking is in charging, import and export identification Aspect research is more, for how to obtain real-time parking space information, the security of vehicle and hommization parking from the aspect of Deficiency, overall intelligence degree is not high.User can not obtain parking information on one's own initiative, it is impossible to independently select parking stall;Parking Field is it sometimes appear that one blocks many car phenomenons, i.e. user passes in and out parking lot repeatedly using the same card, stops so that many cars enter The situation in parking lot;And information of vehicles is not put on record, occur entering parking lot after car thief opens a low-grade car acquisition IC-card, stolen The situation for taking another luxury car to leave away, the security of vehicle is difficult to be protected.In summary, a unified parking is set up Service management information system is very important.It can not only improve parking stall management efficiency and the utilization rate in parking lot, moreover it is possible to allow User's active obtaining parking space information, provides the user facility, while the security of vehicle can also be protected, for above-mentioned Problem, spy proposes a kind of smart city cloud computing parking management information system.
