Abstract
Description
Technical Field
[0001] This utility model relates to the field of license plate recognition technology, specifically to a license plate recognition cloud screen all-in-one machine. Background Technology
[0002] With the rapid development of smart technology, license plate recognition in parking lots is becoming increasingly convenient. Currently available integrated license plate recognition machines can directly identify license plates and display the remaining parking spaces on a screen. They can also automatically calculate parking time and fees. Furthermore, the license plate recognition system identifies and matches the extracted license plate number with vehicle information in the community database to determine if the vehicle has permission to enter the community, greatly facilitating parking information management. However, existing license plate recognition machines have relatively small screens and are generally only used to display text information such as parking duration and payment details, thus limiting their functionality. Utility Model Content
[0003] The purpose of this utility model is to provide a license plate recognition cloud screen all-in-one machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a license plate recognition cloud screen integrated machine, including a cabinet, a license plate recognition camera, and a wide-angle camera. A rectangular mounting hole a is provided on the upper front side of the cabinet. The license plate recognition camera is installed on the back of mounting hole a. A rectangular mounting frame is fixedly installed on the front side of the cabinet. An LED display screen is inserted into the front opening of the mounting frame. Positioning grooves running vertically through the LED display screen are provided on both the left and right sides. Multiple glass ball screws are installed on the left and right sides of the mounting frame. After the LED display screen is installed, the front ends of the glass ball screws abut against the positioning grooves. A mounting hole b is provided on one of the left or right sides of the cabinet. A wide-angle camera is installed on the back of mounting hole b. Symmetrical louvers a are provided on both sides of the upper part of the cabinet. Symmetrical louvers b are provided on both sides of the bottom of the cabinet. A horizontal partition is fixedly connected to the bottom of the inner cavity of the cabinet. The lower part of the partition forms an air intake chamber. The louvers b connect the air intake chamber to the outside. A through hole is provided in the middle of the partition. A fan is installed at the through hole. When the fan operates, it blows air upwards to force heat dissipation from the back of the LED display screen.
[0005] Preferably, filter cotton is pasted onto the sidewalls of the air intake chamber to cover the inner side of the louver b.
[0006] Preferably, both louvers a and b are formed by stamping, and the cabinet door is installed on the back of the cabinet via hinges.
[0007] Preferably, the mounting frame is made of sheet metal bending and welding, and the left and right sides of the mounting frame are respectively provided with folded edges, which are used to weld and fix to the cabinet. The back of the mounting frame has a hollow structure to facilitate cable routing.
[0008] Preferably, multiple through-hole screw tubes are welded to both sides of the mounting frame, and the glass ball screws are screwed into the screw tubes and pass through axially.
[0009] Compared with the prior art, the advantages of this utility model are: the use of a large-size LED display screen on the front of the device can achieve a better visual experience when displaying pictures and videos, and the use of a fan for forced heat dissipation can prevent overheating damage. The LED display screen is installed in a snap-fit manner, which facilitates subsequent maintenance and disassembly. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Please see Figure 1-3 This utility model provides a technical solution: a license plate recognition cloud screen integrated machine, including 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 cover 2 is welded on the upper side of the mounting hole a. The width of the rain cover 2 is greater than the width of the mounting hole a. The rain cover 2 is used to prevent rainwater from splashing onto the lens of the license plate recognition camera 3.
[0016] A rectangular mounting frame 12 is fixedly installed on the front side of the cabinet 1. An LED display screen 8 is inserted into the front opening of the mounting frame 12. The LED display screen 8 has vertically penetrating positioning grooves 14 on both the left and right sides (the positioning grooves 14 are opened on the frame). Multiple ball screws 15 are installed on the left and right sides of the mounting frame 12. After the LED display screen 8 is installed, the front end of the ball screws 15 abuts into the positioning grooves 14. Multiple through-hole screw tubes are welded to both sides of the mounting frame 12. The ball screws 15 are screwed into the screw tubes and pass through axially, so that the LED display screen 8 can be easily disassembled and assembled. The modular structure facilitates inspection and maintenance. The mounting frame 12 is made of sheet metal bending and welding. The left and right sides of the mounting frame 12 are respectively provided with folded edges 13, which are used for welding and fixing to the cabinet 1. The back of the mounting frame 12 has a hollow structure to facilitate wiring. The LED display screen 8 can be used to display public service advertisements, unit introductions, and other information. The large size of the LED display screen 8 results in a screen-to-body ratio of over 75%.
[0017] One of the left and right sides of the cabinet 1 has a mounting hole b. A wide-angle camera 4 is mounted on the back of the mounting hole b. A call button is mounted on the side of the cabinet 1 above the wide-angle camera 4. The wide-angle camera 4 is used for two-way intercom. The upper two sides of the cabinet 1 have symmetrical louvers a5, and the bottom two sides of the cabinet 1 have symmetrical louvers b6. Both louvers a5 and b6 are formed by stamping. The louvers ensure ventilation and heat dissipation while preventing rainwater from entering. The back of the cabinet 1 is fitted with a cabinet door 7 via hinges. When the cabinet door 7 is opened, it facilitates 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. The lower part of the partition 9 forms an air intake chamber. The louver b6 connects the air intake chamber to the outside. Filter cotton 11 is pasted on the side wall of the air intake chamber to cover the inside of the louver b6. A through hole is provided in the middle of the partition 9. A fan 10 is installed at the through hole. When the fan 10 is running, it blows air upwards from the back to force heat dissipation of the LED display screen 8 (large-sized displays have high power and generate a lot of heat. The back is located in a closed cavity, which is prone to overheating). Forced heat dissipation is adopted in summer to avoid damage to the 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 understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
