[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0015] See also Figure 1-3 The present invention provides a technical solution: a license plate recognition cloud screen integrated machine, comprising a cabinet 1, a rectangular mounting hole a is provided on the front side of the upper end of the cabinet 1, a license plate recognition camera 3 is installed on the back of the mounting hole a, a rain shield 2 is welded on the upper side of the mounting hole a, the width of the rain shield 2 is greater than the width of the mounting hole a, and the rain shield 2 is used to prevent rain from falling on the lens of the license plate recognition camera 3.
[0016] A rectangular installation frame 12 is fixedly installed on the front side of the cabinet 1. The front opening of the installation frame 12 is inserted with an LED display screen 8. Positioning grooves 14 that penetrate up and down are provided on the left and right sides of the LED display screen 8 (the positioning grooves 14 are provided on the frame). A plurality of glass bead screws 15 are respectively installed on the left and right sides of the installation frame 12. After the LED display screen 8 is installed, the front end of the glass bead screws 15 press into the positioning grooves 14. A plurality of through screw tubes are welded on both sides of the installation frame 12. The glass bead screws 15 are screwed into the screw tubes and penetrate axially, so that the LED display screen 8 is convenient for overall disassembly and assembly, and the modular structure is convenient for inspection and maintenance. The installation frame 12 is made of sheet metal bending and welding. Folding edges 13 are respectively provided on the left and right sides of the installation frame 12. The folding edges 13 are used for welding and fixing with the cabinet 1. The back of the installation frame 12 is a hollow structure for easy wiring. The LED display screen 8 can be used to publish public service advertisements, unit introductions and other information. The large size of the LED display screen 8 makes the entire screen ratio reach more than 75%.
[0017] A mounting hole b is provided on one of the left and right sides of the cabinet 1. A wide-angle camera 4 is installed on the back of the mounting hole b. A call button is installed on the side of the cabinet 1 above the wide-angle camera 4. The wide-angle camera 4 is used for two-way intercom. Symmetrical blinds a5 are provided on both sides of the upper part of the cabinet 1, and symmetric blinds b6 are provided on both sides of the bottom of the cabinet 1. The blinds a5 and b6 are formed by stamping. The blinds ensure ventilation and heat dissipation while preventing rain from entering. A cabinet door 7 is installed on the back of the cabinet 1 through a hinge. After the cabinet door 7 is opened, it is convenient to carry out installation, wiring, maintenance and other operations.
[0018] A horizontal partition 9 is fixedly connected to the bottom of the inner cavity of the cabinet 1, and the lower part of the partition 9 forms an air intake cavity. The shutter b6 connects the air intake cavity with the outside. Filter cotton 11 is pasted on the side walls of the air intake cavity to cover the inner side of the shutter b6. A through hole is provided in the middle of the partition 9, and a fan 10 is installed at the through hole. When the fan 10 is running, air is blown upward to force heat dissipation from the back to the LED display screen 8 (large-sized display screens have higher power and generate more heat, and the back is located in a closed cavity, which is prone to overheating). Forced heat dissipation is adopted in summer to avoid damage to internal components of the LED display screen 8 due to excessive internal temperature.
[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
