The invention relates to the technical field of license plate recognition, in particular to a license plate recognition device which comprises a stand column, a lower cavity, a middle cavity and an upper cavity are formed in the stand column, a rotating shaft is rotationally connected between the inner walls of the front side and the rear side of the lower cavity, and the end, penetrating and extending out of the stand column, of the rotating shaft is fixedly connected with a guard bar. And the outer wall of the rotating shaft located in the lower cavity is coaxially and fixedly connected with a straight gear. According to the license plate recognition device, when no vehicle passes, two semi-rectangular covers can protect a camera, when an infrared sensor senses that the vehicle arrives, a gear motor drives a bidirectional threaded rod to rotate, the bidirectional threaded rod drives two movable plates to move outwards, and under the elastic force effect of a first spring, an L-shaped plate is driven to move outwards; the two semi-rectangular covers move towards the two sides respectively, the camera is exposed, the camera can shoot the license plate of the vehicle under the control of an external controller, and the guard bar is lifted up subsequently.
本发明涉及车牌识别技术领域,具体为一种车牌识别装置,包括立柱,所述立柱的内部开设有下部空腔、中部空腔和上部空腔,所述下部空腔的前后侧内壁之间转动连接有转轴,所述转轴贯穿延伸至立柱外部的一端固定连接有拦杆,位于下部空腔内部的所述转轴的外壁同轴固定连接有直齿轮。该种车牌识别装置,当没有车辆经过时,两个半矩形罩可以对摄像头进行保护,当红外线感应器感应到车辆到来,减速电机带动双向螺纹杆转动,双向螺纹杆带动两个活动板向外侧移动,在第一弹簧的弹力作用下,带动L型板也向外侧移动,两个半矩形罩分别向两侧移动,将摄像头露出,摄像头即可在外部控制器的控制下对车辆牌照进行拍摄,以及后续的拦杆抬起。
