Specific embodiment
Embodiment 1
As shown in Figure 1-3, the present embodiment provides a kind of license plate recognition device, including pedestal 1, waterproof cabinet 2, high definition license plate
Identify video camera 3, shield 4, auxiliary lighting apparatus 5 and display screen 6, be equipped in waterproof cabinet 2 loudspeaker arrangement 7, controller 8 and
Information recognition device 9, waterproof cabinet 2 are set on pedestal 1, and display screen 6 is set in waterproof cabinet 2, high definition Car license recognition video camera 3
It is fixed on 6 upper end of display screen by rotary driving machine frame 10, rotary driving machine frame 10 includes chassis 11, turntable 12 and rotary electric machine
13, chassis 11 and turntable 12 are connected by bearing 14, and bearing 14 is connect with the rotary electric machine 13 being set to inside chassis 11, turntable 12
