Specific embodiment
The present invention is further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1.
A kind of license plate recognition device, including host 11, camera 12, shield 13 and preventing atomization mechanism.Shield 13 is used for
Protect camera 12.Preventing atomization mechanism is used to eliminate the water mist that may influence the shooting of camera 12, to improve the shooting of camera 12
Clarity.Camera 12 is set to host 11, carries camera 12 by host 11.Shield 13 covers at camera 12 and is connected to host
11, shield 13 protects camera 12 and forms a cavity for accommodating camera 12.Preventing atomization mechanism of the invention includes semiconductor system
Cold 141 and cotton 142, semiconductor chilling plate 141 have chill surface 1411 and heating face 1412, and cotton 142 plays conduction
The effect of moisture.There is shield 13 of the invention first through hole 131 and the second through-hole 132, semiconductor chilling plate 141 to be embedded at
First through hole 131, inside surface is chill surface 1411, outside surface is heating face 1412；Cotton 142 is arranged in
Two through-holes 132, one end of the cotton 142 is connected to chill surface 1411, the other end is connected to heating face 1412.
Its working principle is that: semiconductor chilling plate 141 works, and is formed positioned at the intracorporal chill surface 1411 of 13 chamber of shield low
Temperature, so that the intracorporal condensate moisture of chamber forms water droplet and conduct along cotton 142 in the surface of chill surface 1411.Positioned at protection
Heating face 1412 outside cover 13 forms high temperature, is evaporated by the moisture that cotton 142 transfers out.To guarantee inside shield 13
Drying, prevent from forming water mist, to eliminate influence of the water mist to image-capturing resolution.
Shield 13 and host 11 of the invention surrounds an airtight cavity, and camera 12 is dissolved in the cavity.Preventing atomization mechanism
121 direction of camera lens of neighbouring camera 12 is arranged, and can not form water mist inside such shield 13, due to preventing for face camera lens 121
For shield 13 adjacent to semiconductor chilling plate 141, external heating face 1412, which forms high temperature, prevents 13 outer wall of face shield from being formed
Water mist.In this license plate recognition device, in order to facilitate the conduction of moisture, the second through-hole 132 is located under first through hole 131
Side, due to the effect of gravity, moisture flows to the second through-hole 132 along cotton 142, passes through the second through-hole 132 later by rainbow
It inhales effect and rises to the evaporation of 1412 heat of heating face along cotton 142.The fixed point of cotton 142 is set to chill surface 1411
Or the edge region in heating face 1412.Specifically, one end is fixed on chill surface 1411 with rivet using cotton 142
Surrounding makes its cotton yarn cover entire chill surface 1411, and the other end, which is fixed on 1412 surrounding of heating face with rivet, keeps the covering of its cotton yarn whole
A heating face 1412.
The host 11 of license plate recognition device of the present invention includes controller 15, and controller 15 is connect with semiconductor chilling plate 141,
Control the work of semiconductor chilling plate 141.The host 11 further includes temperature controller 16 and fan 18；Temperature controller 16 and controller 15 connect
It connects, controller 15 is connect with fan 18, acquires the humidity in shield 13 using temperature controller 16, and increase its sky using fan 18
Flow of air.The host 11 further includes power module 17, is connect by power module 17 with controller 15, provides electric energy.
In order to enhance the effect of preventing atomization, which is set as and covers, and distribution is set to shield 13.
The present invention adds preventing atomization mechanism on shield 13, can eliminate because license plate recognition device interior humidity is than outer
Portion's humidity is high, causes the moisture in inner air to evaporate and is attached on shield 13 and camera lens 121 so that generating atomization leads to mirror
First 121 is unintelligible, identifies difficult technical problem, is arranged after preventing atomization mechanism, reduces the humidity in shield 13, reduces anti-
Moisture in shield 13 eliminates the water mist outside 12 camera lens 121 of camera and shield 13, can be improved the identification of license plate recognition device
Precision.
A kind of Car license recognition glass of the present invention, including glass body, further include the preventing atomization mechanism such as above structure.Its glass
Glass ontology has first through hole 131 and the second through-hole 132；Semiconductor chilling plate 141 is embedded at first through hole 131, inside
Surface is chill surface 1411, outside surface is heating face 1412；Cotton 142 is arranged in the second through-hole 132, the cotton
142 one end is connected to chill surface 1411, the other end is connected to heating face 1412.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
