[0018] 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 of the embodiments.

[0019] Reference Figure 1-3 A portable barcode scanner gun is shown, comprising:

[0020] Shell 1, which contains a circuit board and a K230 chip. The K230 chip adopts a new multi-heterogeneous unit acceleration computing architecture, integrates two RISC-V high-efficiency computing cores, and has a built-in new generation KPU (Knowledge Processing Unit). ProcessUnit) intelligent computing unit, with multi-precision AI computing power, widely supports general AI computing frameworks, and the utilization rate of some typical networks exceeds 70%. The shell 1 is set as a rectangular parallelepiped, and a gripping handle 2 is arranged in parallel on one side of the shell 1. The two ends of the gripping handle 2 are respectively fixedly connected to the upper and lower ends of the shell 1 to form an integrated structure with a small volume. A groove is arranged on the lower side of the shell 1, and a camera 3 and an LED light 4 are arranged in the groove. A display screen 5 and an operation button 6 are arranged on the upper end of the shell 1. The code can be scanned reversely by holding it, which is convenient to operate. A rechargeable power supply is also arranged in the shell 1, which uses the existing technology to play a power supply role. A charging socket 7 electrically connected to the rechargeable power supply is fixedly arranged on the shell 1. When the device is in use, pressing the operation button 6 can light up the LED light 4, and the camera 3 is activated to start collecting images. The image information is transmitted to the K230 chip through the circuit board to complete the two-dimensional code recognition. Finally, the K230 chip displays the information on the display screen 5.

[0021] When not in use, in order to protect the camera 3, a sealing plate 8 is matched in the opening of the groove. One end of the sealing plate 8 extends through the shell 1 to the outside and is fixedly connected to a strip block 9. Two sliders are symmetrically fixed on both sides of the other end of the sealing plate 8. Two sliding grooves matching the sliders are symmetrically arranged on the two inner walls of the groove. The sealing plate 8 can be slid to control the opening and closing of the groove. The position of the sealing plate 8 is limited by the friction between the slider and the sliding groove. The slider can be set to be a rubber material and placed in the sliding groove.

[0022] The internal components of the overall device are highly integrated, so better heat dissipation is required. Therefore, a number of heat dissipation fins 10 connected to the inside are evenly fixedly arranged on the end surface of the shell 1 away from the gripping handle 2 to facilitate the heat dissipation operation.

[0023] In order to facilitate the holding of the entire device, a plurality of holding grooves are provided on the holding handle 2, and a rubber anti-slip sleeve is fixedly provided on the holding handle 2.

[0024] In some embodiments, an OpenMV embedded image processing module is provided in the shell 1. The OpenMV embedded image processing is a low-cost open source machine vision module. The AI ​​model is developed and trained through the Openmv platform, and is equipped with a low-power K230 processing chip with AI algorithm to achieve higher scanning code recognition rate and repeatability at a lower cost, while reducing costs and providing higher installation flexibility.

[0025] In order to place it stably and avoid wear, a ring-shaped placement pad 11 is fixedly provided at the bottom of the shell 1 so as not to affect the camera 3 and the LED light 4 in the groove.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
