Description
Technical field
The invention belongs to the static intelligent transportation field in city, and in particular to one kind is realized using GSM/GPRS double frequencies module stops
Car pool information（Including remaining parking stall, total space, Freight Basis etc.）Upload server supplies the device that mobile phone A PP is inquired about.
Background technology
With the raising of the fast-developing living standards of the people of automobile industry, the construction speed of city parking position does not catch up with car
Growth rate, causing parking stall, supply falls short of demand, causes the problem of city parking is difficult.To alleviate city parking pressure, except adding
The planning and construction on fast parking stall, the intelligent stopping guide system of design are also a kind of effective come the utilization rate for improving existing parking stall
Approach.Traditional intelligent parking lot is managed using multiple computers constructing local network, and this management is disadvantageous in that parking lot
Information is closed, and extraneous car owner can not learn whether parking lot has vacant parking stall, and the parking of car owner's blindness adds parking difficulty
Problem.And the present invention accesses parking position information of park using mobile phone A PP, parking turnover rate is improved, is alleviated significantly
The problem of city parking is difficult.
Closest prior art is to think carefully that company puts into operation for 2009 in Suzhou Pingjiang District by Shanghai with the present invention
Vehicle guidance device, its technical scheme is as shown in Figure 1：Passed including magnetic card transceiver module 1, main controller module 2, GSM data
Transmission link 3 and data disaply moudle 4.Card taking or also block, magnetic card transceiver module 1 at banister magnetic card transmitting-receiving before vehicles while passing parking lot
By vehicles while passing information transfer to middle controller module 2, the information of vehicles received processing is obtained residue by main controller module 2
Parking stall number and pack the number that will be shown to data disaply moudle 4, data disaply moudle is transmitted by GSM data transmission links 3
Shown according to parsing by LED dot matrix screens.
The problem of vehicle guidance technology is present be：Some vehicles do not take card directly to march into the arena, and cause actual parking stall and display
Parking stall number is not inconsistent；Only car owner reaches the specified place that dot matrix screen is established, and just can know that the remaining parking space information in parking lot；Due to point
The size limitation of battle array screen, the parking lot number of display is very little；The cost of GSM data transfers is higher, and real-time is poor.
The content of the invention
The object of the present invention is to overcome the problems of the prior art, and meeting car owner, anywhere can be looked at any time
The requirement of parking position information of park is ask, a kind of new parking lot parking space information data upload server of design is inquired about for mobile phone A PP
