[0016] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.

[0017] The embodiment of the present application discloses a detection and authentication information processing device. Referring to Figures 1-3 , a detection and authentication information processing device includes a handle 1, and a control button 6 is installed on the handle 1, allowing the user to manually input data when the barcode or QR code cannot be read, and can adjust the parameters of the device. The end of the handle 1 is hinged with a gun head 2 through a damping rotating shaft, and a display screen 4 is installed on the top of the gun head 2, and the scanned data can be directly displayed on the display screen 4, which is convenient for the user to immediately confirm the scanned data information.

[0018] Referring to Figure 2, a groove is provided on the side of the gun head 2, and the installation plate is installed in the groove through bolts. A scanning assembly 3 is installed on the installation plate. The scanning assembly 3 includes a scanning head 301 on the installation plate. An aperture stop 302 is installed outside the scanning head 301 on the installation plate. A polarizing plate 304 is installed inside the aperture stop 302. A plurality of LED lamp beads 303 are installed outside the scanning head 301 on the installation plate. The LED lamp beads 303 are connected in parallel with each other. A diffuser plate 305 is installed between the inner wall of the groove and the aperture stop 302. Among them, the polarizing plate 304 and the diffuser plate 305 can select appropriate material structures according to needs. For example, the polarizing plate 304 is installed with a transparent glass plate at a 45° inclination, and an anti-reflection coating is installed on the surface of the transparent glass plate to change the reflection path of light and reduce the light directly reflected into the lens of the scanning head 301. The diffuser plate 305 is selected as frosted glass, which can reduce the intensity of direct light and thus reduce the reflection phenomenon.

[0019] Refer to Figure 1 , a light intensity detection module 5 is installed outside the scanning assembly 3 on the gun head 2. The light intensity detection module 5 is used to detect the ambient light intensity, automatically adjust the number of lit and extinguished aperture stops 302, and further adjust the intensity of supplementary light. Through a control system equipped with an STM32 series single-chip microcomputer, cooperating with a gate circuit integrated with a MOSFET switch, the lighting and extinguishing of the LED lamp beads are controlled to automatically adjust the intensity of supplementary light.

[0020] The implementation principle of an authentication information processing device in an embodiment of this application is as follows:

[0021] The user adjusts the angle of the scanning gun head 2 through the handle 1 of the handheld device to align it with the barcode or QR code to be scanned. The scanning head 301 in the scanning assembly 3 starts to work and emits light through the built-in LED lamp beads 303 to illuminate the area to be scanned. During the scanning process, the light intensity detection module 5 continuously monitors the ambient light intensity. When the ambient light is too strong or too weak, the system controlled by the STM32 series single-chip microcomputer will automatically adjust the number of lit and extinguished LED lamp beads 303 according to the feedback of the light intensity detection module 5, so as to adjust the intensity of supplementary light and ensure the scanning quality. The light passes through the aperture stop 302 to limit the light path range, and then passes through the diffuser plate 305 to evenly distribute the light, reducing reflection and shadow. After the light is reflected back to the scanning head 301, it is converted into an electrical signal for decoding processing.

[0022] The decoded data is directly displayed on the display screen 4 for the user to confirm immediately. If the scanning is successful, the user can select further operations according to needs, such as data storage, printing, or transmission, etc. If the scanning fails, such as the barcode is blurred, damaged, or the QR code cannot be recognized, the user can manually input data or adjust the device parameters through the control button 6.

[0023] After the user has completed all operations, they can choose to turn off the device or put it into standby mode. Before shutting down, the device will clean up and save data to ensure that the data is intact and error-free when it is powered on again.

[0024] Finally, the following points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected.
