They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantial technical significance.

Changes or adjustments in their relative relationships should also be considered as the scope of the implementation of the present invention without substantially changing the technical content.

[0021] First, let's explain the original intention of this invention: Currently, there's a lack of equipment on the market that directly checks the markings on power banks, relying instead on manual identification and comparison. Furthermore, existing technology struggles to accurately scan very small text, and struggles to analyze the varying colors, surface materials, and silkscreen font sizes of power banks. Therefore, there's a need for an automated device that can automatically check the markings on power banks.

[0022] In order to make the above-mentioned objectives, features and advantages of this application more obvious and easy to understand, the specific implementation methods of this application are described in detail below with reference to the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of this application.

[0023] In this embodiment of the present invention, Figure 1-Figure 3 As shown, a tool for mobile power compliance inspection is provided, including: Shell 1; A light-transmitting panel 2 is provided on the upper portion of the housing 1 and is used to carry the mobile power supply to be inspected and transmit light; A light source 7 is arranged along the edge of the light-transmitting panel 2 to provide uniform illumination for the information surface of the mobile power supply; A high-definition camera 6 is fixed below the light-transmitting panel 2 and is used to capture images of the mobile power supply information surface; A display panel 3 , which is integrated on the surface of the housing 1 and is used to display the compliance inspection results and information of the mobile power supply; and The prompt light source 4 and the audio component 5 are both arranged on the shell 1, and are used to feedback the compliance inspection results of the mobile power supply through light color and sound respectively.

[0024] The processing module is arranged in the housing 1 and is used to perform image preprocessing, mobile power compliance judgment and control the coordinated operation of various components.

[0025] Through the above scheme, the present invention has built a complete and integrated mobile power compliance inspection hardware system. Through the collaboration of various components, it realizes the full process of automated inspection from image acquisition and processing to result feedback, adapting to market demand and actual inspection scenarios, and can improve inspection efficiency and accuracy, and reduce human intervention errors. The housing 1 provides a physical foundation, the light-transmitting panel 2 ensures load bearing and light transmission, the light source 7 improves lighting uniformity, the high-definition camera 6 accurately captures images, the display panel 3 realizes human-computer interaction and displays the compliance inspection results of the mobile power supply, the prompt light source 4 and the audio component 5 provide multi-dimensional feedback, and the processing module coordinates the algorithm and hardware collaboration, covering the entire "acquisition-processing-judgment-feedback" link.

[0026] Specifically, the shell 1 serves as the "frame" of the device, and is selected with a size and material suitable for the inspection scene (such as lightweight, drop-resistant plastic / metal). Space is reserved inside for installing processing modules, power supplies, etc., and component installation positions are planned on the outside (transparent panel embedded in the upper part, display panel integrated surface, etc.).

[0027] The translucent panel 2 is made of acrylic material (the requirements of translucency and flatness are mentioned in the briefing), embedded in the upper part of the shell 1, forming an operating surface for placing the mobile power supply. The thickness / transmittance is adapted to the optical requirements of the light source 7 and the high-definition camera 6, ensuring uniform light transmission and clear image capture.

[0028] The light source 7 is arranged along the edge of the transparent panel 2 (such as surrounding it), using COB LED or independently controllable lamp body, connected and controlled by a circuit board. After power is turned on, it projects uniform light to the transparent panel 2 in a specific direction, covering the mobile power supply information surface.

[0029] The high-definition camera 6 is fixed directly below the light-transmitting panel 2 (such as through a bracket / card slot), and the focusing distance matches the operating area of ​​the light-transmitting panel 2 (such as 120mm×160mm). It uses a high-pixel sensor (such as 10 million pixels) to capture the information surface image of the mobile power supply, and transmits data through a data cable to the processing module.

[0030] The display panel 3 integrates an LCD screen and a touch layer, and is connected to the processing module via a cable. The display interface includes an "inspection result area" (displaying OK / abnormal), an "information display area" (presenting 3C, model, etc.), and an "operation area" (manually triggering inspection, etc.). The touch signal is analyzed by the processing module to execute the corresponding instructions.

[0031] The prompt light source 4 (such as RGBLED) is installed on the top / conspicuous place of the shell 1, connected to the processing module through a wire, and lights up the corresponding color after receiving the "compliance / abnormality" signal; the audio component 5 (speaker) is built into the shell 1, connected to the processing module, and plays the preset prompt sound / alarm sound after being triggered.

[0032] The processing module uses an embedded motherboard (such as ARM+FPGA architecture) with built-in image processing algorithms (OCR, image enhancement, etc.), database retrieval logic, and hardware control programs. It connects various components through interfaces (GPIO, USB, etc.) and coordinates image acquisition triggering, pre-processing execution, compliance judgment, and result feedback instruction sending.

[0033] In summary, the present invention can realize automatic inspection of mobile power supply identification information, and improve lighting uniformity through the light source 7, and the high-definition camera 6 accurately captures images. At the same time, it can accurately scan very small text, and can also scan and analyze the different characteristics of the mobile power supply in terms of color, surface material, silk screen font color, and size.

[0034] In one embodiment of the present invention, the prompt light source 4 is a multi-color light source, which is used to indicate different compliance inspection results of the mobile power supply. For example, two light sources, red and green, are used, where one color indicates that the mobile power supply compliance inspection result is compliant, and the other color indicates that the mobile power supply compliance inspection result is abnormal.

[0035] It should be noted that the present invention corresponds to different mobile power compliance inspection results through different colors, allowing inspectors to quickly and intuitively identify the results, improve information transmission efficiency, and adapt to the efficiency requirements in inspection scenarios.

[0036] Specifically, if the hardware of prompt light source 4 supports color switching (e.g., an RGB LED capable of controlling dual-color outputs of red and green), the processing module can send a corresponding control signal to prompt light source 4 (e.g., a high level triggers green, a low level triggers red) based on the compliance judgment result (a Boolean value: compliant / abnormal). This allows for simple and efficient hardware and algorithm collaboration. Hardware Selection: Prompt light source 4 uses a dual-color controllable LED (e.g., a common-anode RGB LED that switches between red and green by controlling the pin voltage). This LED is soldered to the device's circuit board and has a reserved control interface for connecting to the processing module.

[0037] In one embodiment of the present invention, the light source 7 includes a plurality of independently controllable lamp bodies, and the brightness of the lamp bodies can be adjusted to adapt to the difference in reflectivity of the mobile power supply surface.

[0038] It should be noted that due to the diverse surface conditions of power banks (such as materials, colors, text printing / engraving methods, and areas), the reflectivity of these surfaces varies significantly. Traditional single-brightness light sources can easily lead to overexposure or underexposure of images, affecting recognition accuracy. This invention utilizes an independently controlled, brightness-adjustable lamp to dynamically adapt to the reflective properties of different power bank surfaces, optimizing image acquisition quality, ensuring the accuracy of subsequent OCR recognition and model matching, and improving the device's compatibility with complex scenarios.

[0039] Specifically, the light source 7 is composed of multiple independent lamps (e.g., LED strips distributed along the four edges of the light-transmitting panel 2). The processing module adjusts the brightness of each lamp using PWM (pulse width modulation) technology. Combined with recognition logic (automatically analyzing image exposure characteristics), the algorithm outputs corresponding brightness parameters, and the hardware performs dimming, automatically adapting to the surface conditions of the power bank.

[0040] Specific implementation method: Hardware design: The light source 7 adopts segmented COB LED, each segment of the lamp body is equipped with an independent driving circuit, and receives the PWM dimming signal of the processing module.

[0041] Control logic: The processing module automatically identifies the image exposure characteristics through image preprocessing and feeds back to the light source 7 to readjust the lighting.

[0042] Brightness adjustment: The processing module outputs a PWM signal (different duty cycles correspond to different brightness) based on the recognition results, and the drive circuit adjusts the lamp current to achieve brightness adaptation.

[0043] In one embodiment of the present invention, a wireless communication module is further included, which is disposed in the housing 1 and is used to: Synchronize the compliance inspection results of mobile power supplies to the mobile terminal for display; Receive updated data from the cloud-based mobile power model library; Remotely trigger the alarm feedback of the audio component 5.

[0044] It's important to note that traditional inspection equipment operates in isolated data zones, making it difficult to synchronize the latest market data (such as 3C status updates and recall batch additions). Furthermore, feedback is limited to local locations, making it unable to meet the needs of remote monitoring and multi-terminal collaboration (such as airport inspectors working with backend data centers). This invention, however, establishes a data exchange channel between the equipment and external devices (mobile terminals and the cloud), enabling cross-terminal display of results, dynamic market data updates, and remote alarm triggering. This improves the intelligence and collaboration of the equipment and adapts to the needs of modern inspection management.

[0045] Specifically, the wireless communication module (such as a 4G / 5G / Wi-Fi module) establishes a connection between the device and the external network. The processing module interacts with the module via AT commands and network protocols (HTTP / MQTT) to send and receive data. Combined with the development of a cloud server and mobile terminal app, data synchronization and remote control are achieved. Specifically, the wireless communication module uses an industrial-grade module compatible with the device (such as a 4GCat.1 module), connected to the processing module via an SPI / USB interface, and a built-in SIM card / network configuration module enables network access. After generating inspection results, the processing module invokes a network communication program to encapsulate the result data (including mobile power bank information and compliance status) in JSON format and send it to the cloud server via an HTTP POST request. The mobile terminal app (pre-bound to the server) polls / receives push notifications, parses the data, and displays it. The cloud server pushes database update packages (including 3C status and recall information) on a scheduled or on-demand basis. The device pulls the update packages via HTTP GET requests. The processing module verifies the updates and writes them to local storage, updating the database. The cloud server or authorized mobile terminal sends an "alarm command" (such as detecting a high-risk violation batch), and the device subscribes to the command topic through the MQTT protocol. After the processing module receives the command, it calls the audio component 5 control program to trigger an alarm feedback.

[0046] like Figure 1-Figure 4 As shown, the present invention also discloses a method for mobile power compliance inspection, which is based on a tool for mobile power compliance inspection and includes the following steps: S1, place the information surface of the mobile power supply on the light-transmitting panel 2; S2, start the light source 7 and the high-definition camera 6 to collect the image of the mobile power supply information surface; S3, performing pre-processing operations on the mobile power supply information surface image through the processing module and extracting key content information; S4, searching a preset mobile power supply model library using the extracted key content information, performing a mobile power supply compliance check according to preset rules, and obtaining a mobile power supply compliance check result; S5, the compliance inspection result of the mobile power supply is synchronously fed back through the display panel 3, the prompt light source 4 and the audio component 5.

[0047] S6. Prosecutors make final judgments based on the compliance inspection results of mobile power supplies.

[0048] It's important to note that existing inspection processes lack standardized methods, leading to arbitrary manual operations that can easily lead to missed inspections and misjudgments. Furthermore, the various steps (collection, processing, judgment, and feedback) are loosely connected, making it impossible to efficiently collaborate with device hardware to achieve automated inspections. This invention, however, establishes a standardized inspection process based on device hardware, standardizing all steps from "power bank placement" to "result feedback." By deeply collaborating algorithms and hardware, it achieves automated and precise inspections, improving inspection efficiency and consistency and meeting market demands.

[0049] Specifically, a manual operation involves placing the power bank's information surface against the translucent panel 2, triggering the device's "Waiting for Inspection" state. (Optional: Click "Start Inspection" on the display panel 3, or the device automatically recognizes the placement action via a pressure sensor.) Upon receiving the "Start Inspection" signal, the processing module sends a "lighting command" to the light source 7 and a "photographing command" to the high-definition camera 6. The light source illuminates, and the camera captures an image and transmits it to the processing module. The processing module invokes built-in algorithms (such as image enhancement and target detection) to pre-process the image. It then uses optical character recognition (OCR) to extract key information and store it in memory for subsequent analysis. Using the extracted key information as search criteria, the processing module accesses a local database of pre-set power bank models (including 3C certification status, recall status, manual rejection, and manual release), executes matching logic, and generates inspection results. The processing module then sends a "result display command" (containing the results and power bank information) to the display panel 3, a "color command" to the prompt light source 4, and a "sound command" to the audio component 5, providing simultaneous multi-dimensional feedback.

[0050] In one embodiment of the present invention, the steps of starting the light source 7 and the high-definition camera 6 to capture the image of the mobile power supply information surface include: Obtaining exposure features of the mobile power supply information surface image; According to the exposure characteristics of the mobile power supply information surface image, the brightness of the light source and the exposure time of the high-definition camera are adjusted to adapt to the difference in reflectivity on the mobile power supply surface.

[0051] It should be noted that the present invention introduces an adaptive mechanism in the image acquisition link to adjust the brightness of the light source and the exposure time of the high-definition camera according to the exposure characteristics of the mobile power supply information surface image, dynamically adjusts the brightness of the light source and the exposure time of the high-definition camera, optimizes the image quality, provides a clear data source for subsequent preprocessing and identification, and improves inspection accuracy.

[0052] Specifically, before step S2, the processing module calls the image preprocessing algorithm to automatically adjust the exposure time of the high-definition camera 6 and the brightness of the light source 7 according to the image exposure characteristics. When the image is too bright, the exposure time of the high-definition camera 6 is first reduced. If the exposure time of the high-definition camera 6 is reduced to the minimum value and is still too bright, the image exposure is further adjusted by reducing the brightness of the lighting source. When the image is too dark, conversely, the brightness of the light source 7 is first increased, and then the exposure time is increased.

[0053] In one embodiment of the present invention, the steps of performing a pre-processing operation on the mobile power supply information surface image by the processing module and extracting key content information include: Enhance the details of the mobile power supply information surface image by adjusting sharpness, brightness, and contrast; Locate the mobile power area in the mobile power information surface image through target inspection; Rotation correction adjusts the image of the mobile power supply information surface to the horizontal positive direction; Use OCR recognition to extract key content information from the mobile power supply information surface image; Correct key content information based on a preset library of common recognition errors.

[0054] It should be noted that this invention utilizes standardized and refined image preprocessing and OCR recognition processes to enhance image detail, eliminate interference, correct angles, and accurately extract key information, providing an accurate data source for compliance judgment and reducing recognition errors. Specifically, the processing module possesses algorithmic execution capabilities (the embedded motherboard supports image processing and OCR engines). Preprocessing operations can be implemented using libraries such as OpenCV, while OCR recognition can integrate engines such as Tesseract. Combined with a pre-set library of common recognition errors (built based on common recognition issues), the hardware and software collaboratively cover the entire "image-to-text-to-information" conversion process.

[0055] Specifically, the processing module calls the OpenCV library function to perform the following operations on the acquired image: Sharpening: Enhance the edge clarity of text using the UnsharpMask algorithm (e.g., parameter settings: radius 1.0, amplitude 1.5); Brightness / contrast adjustment: CLAHE (Contrast Limited Adaptive Histogram Equalization) is used to improve overall contrast and enhance details.

[0056] Target Inspection (ROI): Use a deep learning-based target inspection model (such as YOLOtiny) to select the mobile power bank area in the image, crop it, and remove the background to reduce interference.

[0057] Rotation correction: Use Hough transform to check the edge straight lines of the mobile power information surface in the image, calculate the tilt angle (such as -30°~30°), and use affine transformation to rotate the image to the horizontal positive direction.

[0058] OCR recognition: Integrates the Tesseract OCR engine, loads a custom-trained mobile power character recognition model (adaptive to small text and diverse fonts), performs text recognition on the corrected image, and outputs the recognition results.

[0059] Content correction: The processing module loads the "common recognition error library", matches the OCR recognition results with the error library, corrects errors caused by similar characters and fuzzy characters, and outputs accurate key content information.

[0060] In one embodiment of the present invention, the step of extracting key content information from the mobile power supply information surface image using OCR includes: Locate the text distribution area in the mobile power supply information surface image; Key content information is extracted from the text distribution area. The key content information includes the mobile power compliance identification and the mobile power product identification, such as the 3C logo, mobile power brand, mobile power model and mobile power capacity.

[0061] It should be noted that since the OCR recognition engine supports area positioning and text classification, the processing module can identify the meaning of the text in the image (such as keywords such as "3C" and "capacity") through training models (such as text classification models based on deep learning), and combine coordinate information to screen the core area. The software and hardware work together to achieve precise extraction. The present invention can accurately locate the text area related to compliance inspection in the image, extract core key information (3C logo, mobile power brand, mobile power model and mobile power capacity), provide direct and necessary data support for compliance judgment, avoid interference from irrelevant information, and improve judgment efficiency.

[0062] Specifically, the OCR recognition engine scans the preprocessed image and outputs the coordinates (x, y, w, h) and recognized content of all text areas. The processing module loads a "key information keyword library" (including "3C," "capacity," "model," "brand," etc.), matches the recognized content with the keywords, and filters out related areas (for example, areas containing "3C" are identified as 3C logo areas). For these filtered areas, the text content is extracted and categorized and labeled: "3C" keywords → 3C logo information; "capacity" and "mAh" keywords → capacity information; "model" and "Model" keywords → model information; the rest can be identified as brand information (such as continuous characters without clear keywords), and finally outputs structured key content information.

[0063] In one embodiment of the present invention, the steps of determining compliance of a mobile power supply according to preset rules and obtaining a compliance inspection result of the mobile power supply include: If the key information meets the compliance status in the preset mobile power model library, the mobile power compliance check result is output as compliant. Otherwise, the mobile power compliance check result is output as abnormal. Compliance status includes: valid 3C certificate, non-recalled batch, and complete labeling.

[0064] It should be noted that the present invention converts market requirements into algorithmic logic to ensure that the inspection results accurately adapt to regulatory requirements and assist in the compliance execution of inspection scenarios.

[0065] Specifically, the processing module can access the local / cloud-based preset mobile power model library (including 3C status and recall information). Through keyword matching (3C identification validity, whether the model is on the recall list) and logical judgment ("AND" operation: 3C valid ∧ not recalled ∧ complete identification), the algorithm can efficiently execute the rules and output the judgment results.

[0066] Specific implementation method: The preset mobile power model library stores the status corresponding to the mobile power model, 3C certificate status (valid / invalid); recall status (yes / no); identification complete status (yes / no).

[0067] The processing module uses the extracted "brand + model" as the search key to query the preset mobile power model library. If the 3C status is "valid", the recall status is "no", and the identification complete status is "yes", then the output is "compliant". Otherwise (any one of the items is not met), then the output is "abnormal" to generate the inspection result.

[0068] In one embodiment of the present invention, the step of synchronously feeding back the compliance inspection result of the mobile power supply through the display panel 3, the prompt light source 4 and the audio component 5 includes: Display panel 3 shows the compliance inspection results and information of the mobile power supply; The compliance inspection result of the mobile power supply is displayed through the prompt light source 4; The audio component 5 plays the prompt tone of the mobile power supply compliance inspection result.

[0069] It should be noted that the present invention realizes multi-dimensional and synchronized result transmission through feedback from the display panel 3, prompt light source 4, and audio component 5, ensuring that inspectors can quickly obtain accurate inspection results in complex scenarios such as noisy environments at airports.

[0070] Specifically, after the processing module generates the inspection results, it sends instructions in parallel to: The display panel 3 displays the formatted result (such as "Inspection result: Compliance" + mobile power supply information); the prompt light source 4 lights up the corresponding color (Compliance → green, Abnormality → red); the audio component 5 plays a preset voice (such as "Inspection passed" or "Inspection abnormality, please check").

[0071] Each component executes instructions independently, achieving synchronous feedback of vision (display panel + light source color) and hearing (sound), and improving the efficiency of information transmission.

[0072] The above are merely preferred embodiments of the present application and do not constitute any form of limitation to the present application. Any person skilled in the art can, without departing from the scope of the technical solution of the present application, utilize the methods and technical contents disclosed above to make many possible changes and modifications to the technical solution of the present application, or modify it into an equivalent embodiment with equivalent changes.
