Abstract
The utility model discloses a vehicle license number automatic identification system. In the system, a control host is connected with and controls a display screen, a gate, a camera and a ground induction coil, thereby achieving the judgment on the characteristics of a vehicle. Then the vehicle license number is recognized through the control host and is compared with a database. Vehicle types are obtained through being compared with the database of a memory card, and then the arriving time of the vehicle is recorded and the gate is opened to release the vehicle. If the vehicle is the internal vehicle, the expiry date is shown and the vehicle is released. The vehicle is inducted through the ground induction coil when leaving and the license is shot by the camera. The control host recognizes the license number and compares the license plate with the database, computes parking time and shows the charge. After the charge is paid, the vehicle is automatically released. If the vehicle is the internal vehicle, the effective deadline is shown and the vehicle is released. After the vehicle leaves, the system records the leaving time. The vehicle license number automatic identification system provided by the utility model is simple in structure, simple in operation and the like, and is suitable to widely be used and applied.

[brief description of the drawings]
Fig. 1 is principle schematic of the present utility model.
[embodiment]
Can explain in more detail the utility model by the following examples, the utility model is not limited to the following examples;
A kind of number plate of vehicle automatic recognition system described in 1 by reference to the accompanying drawings, comprise main control system, display screen, gate, camera and ground induction coil, described main control system is by human-machine interface controller control, described human-machine interface controller model is TPC7062K, wherein main control system is single-chip microcomputer, and wherein main control system connects respectively by circuit and controls at least one display screen, gate, camera and ground induction coil; Described ground induction coil rolls to main control system and sends the signal that vehicle will be come in and gone out by line connection control main frame and according to vehicle; Described camera is captured picture by line connection control main frame the signal that sends to main control system according to ground induction coil to vehicles passing in and out, the picture of now capturing can be distant view photograph, also can be the number plate information of vehicle, and the picture of candid photograph is transferred to main control system, main control system, by internal arithmetic, sends start signal to gate; Described gate is realized opening and closing by line connection control main frame the signal that provides according to main control system; Described display screen connects main control system and shows the output information of main control system, and in order better to realize function of the present utility model, main control system connects voice device or warning horn.
Embodiment of the present utility model is:
In the time that vehicle enters:
1, vehicle sails car plate camera into and captures region, triggers ground induction coil, and ground induction coil sends signal to main control system.
2, camera according to the signal providing of main control system capture vehicle close-up image (also can simultaneously capture panoramic picture according to client) and identify the number-plate number, then draw class of vehicle (inner car or interim car etc.) by the database in retrieval main control system.
3, main control system shows the result of retrieval the term of validity (inner car) of this car by display screen by display screen.
4, voice device is play the car plate identifying, and welcome the signal language of Denging.
If 5 non-full positions or this car belong to fixed vehicle situation, gate is let pass, and writes down vehicle entry time simultaneously.Vehicle is crossed import, sails in parking lot, and whole process completes automatically, need not personnel intervention.Vehicle, always in transport condition, suspends without section.
