The efficiency and stability being wirelessly transferred.
Below in conjunction with the accompanying drawings, the Vehicle License Plate Recognition System provided according to the present utility model application is described in detail.
As shown in Figure 1 and Figure 2, a kind of Vehicle License Plate Recognition System, it is characterised in that the Vehicle License Plate Recognition System includes camera
Component 1, support 2 and server 3, wherein, the CCD camera assembly 1 include housing 10, camera body 11, recognition unit 12,
Radio communication unit 13, Signal Booster 14 and antenna 15；Described one end of housing 10 sets opening, and the camera body 11 is set
It is placed in the inside of the housing 10 and towards the opening, the recognition unit 12, the radio communication unit 13 and the signal
Booster 14 may be contained within inside the housing 10；The camera body 11, the recognition unit 12, the wireless telecommunications list
Member 13, the Signal Booster 14 are sequentially connected electrically；The antenna 15 is arranged at the top of housing 10, the antenna 15 and institute
Signal Booster 14 is stated to electrically connect；Wherein, the recognition unit 12 includes DSP recognition units；The housing 10 and the support 2
Connection, the radio communication unit 13 are connected with the radio communication of server 3.
Camera body 11 uses high-definition camera, and recognition unit 12 obtains real-time video from high-definition camera, and knows
Car plate in other video, after identifying successfully, license board information is processed into the character string of JSON forms or XML format, wireless telecommunications
License plate number is sent to clothes by unit 13 by LAN or wide area network according to the network transmission protocol preset with character string forms
Business device 3, the special interface of server 3 carry out relevant treatment after receiving.
The application integrates recognition unit 12 in camera one end, and the captured in real-time image information of camera body 11 is simultaneously sent to
Recognition unit 12, recognition unit 12 are analyzed image information, avoid a picture recognition failure, it is necessary to repeatedly transmit picture
Situation about being identified occurs, and more rapidly, efficiently identifies license board information.
After analyzing successfully, character string is sent to server 3 by radio communication unit 13, with transmission picture to the phase of server 3
Than the size of picture file is much larger than the size of character string, is transmitted using character string, and bandwidth resources take few, character string transmission
Speed is fast, can reduce the requirement to bandwidth and network stabilization, reduces cost, improves efficiency.
License board information is sent to by server by radio communication unit 13, compared with wired forms, Wireless transceiver is reduced
A large amount of hardwires, cost is advantageously reduced, while be advantageous to later maintenance.In addition, transmitting license board information using wireless telecommunications, take the photograph
As the position that head assembly 1 is set can be more flexible.
The transmission of license board information between radio communication unit 13 and server 3, network signal is bad to influence Car license recognition
The operating efficiency of system, it can also influence the application such as follow-up Car park payment, traffic administration.The application is also integrated with camera one end
Signal Booster 14 and antenna 15, improve license board information transmits between radio communication unit 13 and server 3 speed and stably
Property.Antenna 15 can be arranged at the top inside housing 10；Antenna 15 can also be arranged at the top outside housing 10, in housing
10 top drillings, electric wire through the top of housing 10 perforate by the Signal Booster inside electric wire housing 10 outside and housing 10
14 electrical connections.
Server 3 can include home server and director server, and the car plate after identification is sent to home server, this
Ground server does subsequent treatment for car plate, can directly use the result after processing, or will be handled by home server
As a result send to director server.
Wherein, the recognition unit of Vehicle License Plate Recognition System is DSP recognition units, and camera body 11 is by the image information of shooting
DSP recognition units are sent to, license board information is fast and accurately identified in DSP recognition units, and license board information is sent to wirelessly
Communication unit.DSP recognition units have the characteristics of arithmetic speed is high, addressing system is flexible, communication mechanism is powerful.
Wherein, radio communication unit 13 is 2G communication units, 3G communication units, 4G communication units, Zigbee communication units
In any one.
, can using wide area network when radio communication unit 13 is using 2G communication units, 3G communication units or 4G communication units
To realize remote collection license board information, subsequent treatment is carried out to car plate, it is possible to reduce hardware setting quantity, reduce cost.
Zigbee communication units have the advantages that low energy consumption, price are low, safe.
Again as shown in figure 1, CCD camera assembly 1 can also include shielding cover, the shielding cover is connected with the top of housing 10.
Shielding cover exceeds the open at one end of housing 10, and 4~6 centimetres are could be arranged to beyond length, can also be according to shell
The size adjusting of body 10, camera body are arranged at the inside opening one end of housing 10, and shielding cover can be with beyond the part of housing 10
Camera body is further protected, avoiding direct sunlight from entering the camera lens of camera causes fogging image, while avoids housing 10
Openend intakes, and causes other devices in camera body or housing not work；In addition, shielding cover can keep the sun off and rain
Water, sunlight long-term irradiation housing is avoided, housing is heated, accelerate housing aging；Avoid rainwater from drenching housing, cause enclosure interior
Intake or make moist, reduce the housing life-span, influence CCD camera assembly work.The connection of shielding cover and housing 10 can be detachably to connect
Connect, maintain easily and change.
Wherein, housing 10 and the support 2 are be hinged.Housing 10 can rotate up and down, to adjust shooting angle.
Wherein, support 2 is hollow cylindrical structure, and housing 10 is connected with the middle and upper part of the support 2 or top.It is hollow
Structure is advantageous to mitigate weight, reduces material cost.Support 2 can also be cuboid or other structures.
Wherein, the height of support 2 is 1.5 meters~2 meters.Housing 10 and the ground terminal of the tie point distance bracket of the support are
1.2 meters~1.5 meters.
Vehicle License Plate Recognition System is set in traffic intersection, or the place such as the gateway in parking lot, realizes charge or violating the regulations
The function such as take pictures.Support 2 is set perpendicular to the ground, and the ground terminal of the support 2 is one end that support 2 fixes on the ground, shooting
Head assembly 1 is arranged on the other end of support.The height of oversize vehicle, although car plate position is relatively low, is taken the photograph at 1.8 meters~2.2 meters
As head assembly set it is too low easily shelter from camera lens by other material objects, the angle of CCD camera assembly 1 can be adjusted to have reached
Shooting effect.Therefore, it is 1.5 meters~2 meters to choose support height, the housing 10 of CCD camera assembly 1 and the tie point distance of support 2
The ground terminal of support 2 is 1.2 meters~1.5 meters.
The application provide Vehicle License Plate Recognition System, simple in construction, cost is low, can realize it is simple, quick, stably, bandwidth
Resource occupation identifies license board information less, by license board information it is rapid, be stably sent to server, server is directed to license board information
It is further processed, realizes the functions such as intelligent charging, intelligent traffic administration system, adapts to the development of the intelligent transportation of high speed.
Descriptions above can combine implementation individually or in a variety of ways, and these variants all exist
Within the protection domain of the present utility model application.
