Abstract
Description
Technical Field
[0001] This disclosure relates to the field of smart terminal equipment technology, and more specifically, to a contractor data verification terminal device. Background Technology
[0002] In the daily operations of a company, contractor document review is a crucial step in ensuring compliance and the validity of qualifications. Traditional manual review of paper documents is inefficient when dealing with large volumes of contractor data. Reviewers need to expend significant time and effort sifting through the documents, and manual operation is prone to errors. Furthermore, the review process lacks transparency and fails to meet the demands for efficient and accurate review.
[0003] With the advent of the digital age, some companies are attempting to combine general-purpose scanning equipment with software for document review. They use ordinary scanning devices (such as scanners and document cameras) to collect contractor information, and then perform OCR recognition and rule verification through a backend system. While this approach improves efficiency to some extent, the equipment has limited functionality, cannot be optimized for specific review scenarios, and poses security risks during data transmission and storage. Furthermore, the equipment's user interface is complex, requiring training for non-professional users, and the hardware maintenance costs are high. Utility Model Content

[0032] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description
[0033] Figure 1 This diagram illustrates the structure of a contractor data review terminal device provided in an embodiment of the present disclosure.
[0034] Figure 2 A schematic diagram of another contractor data review terminal device provided in an embodiment of this disclosure is shown.
[0035] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0036] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0037] The following is combined with Figures 1 to 2 This invention describes a contractor data verification terminal device according to some embodiments of the present invention.
[0038] like Figure 1 As shown in the figure, one embodiment of this utility model proposes a contractor data review terminal device. The terminal device adopts a three-dimensional layered design, which is divided into an upper user operation area and a lower data processing area. The height of the upper user operation area can be designed within the range of 1.2 to 1.5m to fully adapt to the ergonomic principle, so that the user can maintain a comfortable posture and reduce operation fatigue during use.
[0039] Specifically, the upper user operation area integrates multiple modules, including a replaceable scanning module 10 and an adaptive touchscreen display 20. The replaceable scanning module 10 uses a magnetic quick-release interface (similar to the modular design of the Fujitsu ScanSnap iX1600) for easy module replacement, allowing for quick module switching and significantly improving the device's flexibility and maintenance efficiency. The replaceable scanning module 10 integrates an RGB color scanning head and a dedicated OCR tilt scanning head. The RGB color scanning head has a resolution of up to 600 dpi, enabling color scanning of paper documents and ensuring accurate color reproduction. The dedicated OCR tilt scanning head supports tilt scanning from 10° to 45°, making it well-suited for various applications such as IC card chip reading and electronic screen scanning. OCR technology converts text information in scanned images into editable text formats, and the tilt scanning head expands the application scope of OCR technology.
[0040] Here, the RGB color scanning head can use a JAI prism camera (such as the LT-400CL), employing prism beam splitting technology. After the incident light is split by the prism, three CMOS / CCD sensors capture the red, green, and blue light respectively, forming R / G / B images with the same field of view and angle of view. The dedicated OCR tilt scanning head can refer to the tilt scanning technology implementation of the Epson DS-790WN (such as a built-in angle sensor and automatic image correction algorithm). The tilt scanning function can be implemented in the Epson DS-790WN (supporting 30° tilt shooting), and the IC card reading function complies with the ISO / IEC 14443 standard (such as the ACS ACR39U card reader).
[0041] Meanwhile, the magnetic quick-release interface also features anti-misinsertion positioning pins and flexible conductive contacts. The anti-misinsertion positioning pins provide positioning during module installation, preventing damage to the equipment or affecting its performance due to improper installation. Its magnetic positioning combined with flexible contact design is similar to Apple's MagSafe interface and the anti-misinsertion structure of industrial scanners (Honeywell Captuvo SL22 handheld scanner). The flexible conductive contacts ensure a stable and reliable electrical connection between the module and the device body, avoiding equipment malfunctions or data transmission errors caused by poor contact, thus guaranteeing the stability and reliability of the device connection.
[0042] Understandably, the adaptive touch display 20 integrates a motorized height-adjustable stand and a gravity sensor on the back. The motorized height-adjustable stand uses a rack and pinion mechanism with a damping buffer. Rack and pinion height-adjustable structures are widely used in medical monitors (such as the height-adjustable stand of the EIZO FlexScan EV2780), and the damping buffer technology can be referenced from the Ergotron LX monitor stand. The rack and pinion mechanism is a mechanical structure that transmits power and motion through the meshing of gears and racks, converting the rotational motion of the motor into the linear height-adjustable motion of the display screen. The damping buffer provides smooth damping force during the height-adjustment process, preventing the display from shaking or impacting during rapid height changes, ensuring a smooth and stable adjustment process. This allows the display to support a height adjustment range of 30cm and a tilt adjustment range of 15° to 60°, allowing users to flexibly adjust the position and angle of the display according to their height and usage habits for the best visual experience. Meanwhile, a gravity sensor is a sensor that can sense the direction and magnitude of gravity. It calculates the tilt angle or height of an object by measuring its acceleration in a gravitational field. In the adaptive touch display 20, the gravity sensor is used to automatically identify the user's height information (similar to the automatic rotation technology of mobile phones and tablets, such as the MEMS gravity sensor in the iPhone). When a user stands in front of the display, the gravity sensor can sense the pressure distribution or tilt angle changes exerted by the user's body on the display, and then use algorithms to calculate the user's height, automatically adjusting the height and angle of the display to achieve personalized visual adaptation.
[0043] Furthermore, the adaptive touch display 20's screen surface is covered with anti-glare tempered glass and a viewing angle control film. Anti-glare tempered glass (such as Corning Gorilla Glass) is a tempered glass material with anti-glare properties that effectively reduces light reflected from the screen surface, minimizing glare and improving screen visibility and comfort. The viewing angle control film (such as the 3M PF15.0 series) is a thin-film material with special optical properties that limits the screen's visible angle range. This ensures that only users positioned directly in front or at specific angles can clearly see the screen content, while users viewing from the side cannot see the content or only see a blurry image. This effectively prevents the risk of data leakage from side views and ensures data security. Simultaneously, the display's viewing angle reaches 120°, meaning that users can obtain a relatively clear visual effect within a 120° viewing angle range, further enhancing ease of use and comfort.
[0044] In some possible embodiments, the adjustable height and adjustable angle of the adaptive touch display 20 can also be set according to specific needs, such as a height of 40cm and an angle of 30° to 75°, etc., without being specifically limited here.
[0045] Understandably, the lower-level data processing area is used for analyzing and reviewing the collected data, including the intelligent review module 30, the dual-level data encryption module 40, and the invoice printing module 50. The intelligent review module 30 (which can use an embedded chipset, such as the DS-200) incorporates relevant AI review algorithms, supporting OCR recognition of qualification certificates, logical verification (such as validity period and qualification level matching), and anomaly marking. In actual review processes, this module can complete the review of a single document in a short time, significantly reducing review time and improving work efficiency.
[0046] For example, the intelligent review module 30 can refer to the core technology architecture of Hanvon Technology's Hanvon DS-200 intelligent review terminal or Alibaba Cloud's Intelligent Document Processing Platform (IDP). This module is based on an embedded chipset (such as the NPU acceleration unit built into the DS-200) and integrates deep learning-driven AI review algorithms (such as the OCR-V3 model and rule engine based on the Transformer architecture). Specifically, it implements the following functions: OCR recognition technology, using the Hanvon HW-OCR 12.0 engine or Alibaba Cloud IDP OCR, can support multimodal document parsing (such as PDF, images, scanned documents), achieving an accuracy rate of ≥99.6% for printed / handwritten text recognition on qualification certificates, and automatically extracting key fields (such as certificate number, issuing authority, and validity period). Regarding the logical verification part, it uses NLP to parse natural language expressions such as "expiration date" and automatically compares the current date (e.g., identifying "2025-12-31" and verifying whether it has expired). It also uses a knowledge graph to associate qualification levels with business types (e.g., "Level 1 Construction Engineer" corresponds to "Level 1 General Contracting Qualification for Building Construction"). It connects to the industrial and commercial / regulatory system API to verify the consistency between the company name and the certificate holder in real time. Finally, regarding the anomaly marking part, Hanvon Technology's Hanvon DS-200 intelligent audit terminal can also mark PS modification areas using image tampering detection algorithms (e.g., generation trace recognition based on GAN); it automatically generates red highlight prompts for logical conflicts (e.g., "Level 2 qualification" applying for "Level 1 project") and associates them with specific clauses in the rule base.
[0047] Specifically, the dual-level data encryption module 40 is used to ensure data security. This module includes a hardware-level key generator (which can use an independent security chip, such as model SE-05) and a data encryption chip (such as model AES-256). The data output from the replaceable scanning module 10 is first encrypted by the hardware encryption chip, and then transmitted to the dual-level data encryption module 40 via the encryption bus (with a hardware authentication interface). In the dual-level data encryption module 40, the data undergoes dynamic key verification and data storage area locking again, thus forming a three-level protection system of "data acquisition end encryption → link verification → storage locking," providing comprehensive protection for data security.
[0048] Specifically, referencing the adaptive paper feed control technology of the Fujitsu FP-9000 series industrial document printer and incorporating the structural design innovations of this invention, the document printing module 50 adopts a dual-roller paper clamping mechanism. The drive shaft is equipped with a rubber anti-slip layer, and the driven shaft is equipped with an elastic pressure adjustment mechanism. The roller spacing between the drive and driven shafts can be adjusted from 0.1mm to 3mm. This adaptive paper clamping mechanism can effectively reduce the paper jam rate. When a paper jam occurs in the document printing module 50, it will automatically reverse the paper feed and display the fault location on an adaptive touchscreen display, facilitating timely troubleshooting by the user. Furthermore, the document printing module 50 supports A4 report printing and can complete report output in a short time (e.g., 30 seconds), meeting the user's need for rapid access to review results.
[0049] In one embodiment of this utility model, the upper user operation area and the lower data processing area are connected by a metal heat dissipation partition. The partition is provided with honeycomb heat dissipation holes. Together with the bottom silent fan, it can effectively dissipate the heat generated in the data processing area, keep the data processing area at a low temperature (such as less than 40°C), ensure that the equipment operates in a stable temperature environment, and extend the service life of the equipment.
[0050] In one embodiment of this utility model, to facilitate daily maintenance and troubleshooting, a quick-release maintenance hatch can be installed in the lower data processing area, allowing operators to quickly open the hatch for necessary inspections and repairs. Simultaneously, to improve the efficiency of circuit board replacement and maintenance, a drawer-type circuit board guide rail structure can be introduced into the lower data processing area. This structure allows circuit boards to be easily pulled out, reducing the complex disassembly steps required in traditional maintenance methods and improving maintenance speed and accuracy.
[0051] In one embodiment of this invention, the terminal device's casing can adopt an inverted trapezoidal design, which enhances the device's stability and anti-interference capabilities. The inverted trapezoidal shape helps optimize airflow inside the device, improves heat dissipation, and ensures the device maintains good performance even during prolonged operation. Furthermore, the bottom of the device can be equipped with magnetic anti-slip feet, which effectively prevent the device from sliding during use and provide better stability in environments requiring a fixed position. The magnetic feet facilitate the placement and movement of the device, enhancing its applicability and operational flexibility.
[0052] This utility model's contractor document review terminal equipment, through the collaborative operation of a replaceable scanning module and an adaptive touch screen, achieves rapid digital acquisition of multi-format documents and real-time height adjustment, ensuring operational comfort for users of different heights and the accuracy of data acquisition. Simultaneously, the intelligent review module, through OCR recognition and logical verification functions, can automatically mark abnormal documents, improving the efficiency and accuracy of document review. A dual-level data encryption module ensures data security and avoids the risk of information leakage. The invoice printing module can immediately output a report after review, simplifying the document processing workflow.
[0053] Compared with the existing technology of manually reviewing paper documents for document review, this utility model realizes an intelligent and automated workflow, improves the efficiency and accuracy of contractor document review, solves the problems of cumbersome, inefficient and error-prone manual operation in document review, and also solves the problems of insufficient data security and inconsistent document processing flow.
[0054] like Figure 2 As shown, in one embodiment of this utility model, preferably, the contractor document review terminal device further includes a document inlet 60, which is an inlet component for receiving documents to be reviewed. It has a built-in pressure sensor. When a document to be reviewed is inserted into the inlet, it generates pressure inside the inlet. Upon detecting this pressure change, the pressure sensor automatically triggers the initialization of the replaceable scanning module, preparing it for scanning. This eliminates the need for the user to manually operate the scanning module's start button, simplifying the operation process and improving work efficiency. For example, in practical applications, the contractor only needs to insert the paper document to be reviewed directly into the document inlet, and the scanning module will automatically begin initialization and then scan the document. The entire process is fast and convenient.
[0055] Here, the document feed slot 60 has broad compatibility, supporting the feeding of A4, A3, and irregularly shaped documents. A4 and A3 are common office document sizes, while irregularly shaped documents include some special-shaped or sized materials, such as certain certificates and reports. The maximum width of the feed slot can reach 30cm or 45cm. This design fully considers the feeding needs of different sized documents, ensuring that both narrower documents and wider special-shaped documents can smoothly pass through the feed slot into the device for processing.
[0056] In one embodiment of this utility model, preferably, the contractor data review terminal device further includes a multimodal guidance component 70, integrated into the terminal device housing, which transmits information to the user through multiple sensory channels (such as vision, hearing, and touch), enabling the user to understand the device's status and operational requirements more quickly and accurately. Here, the multimodal guidance component includes a ring-shaped status light strip, a bone conduction speaker, a Braille operation panel, and a vibration feedback module.
[0057] Specifically, a ring-shaped status light strip, located on the front of the terminal device, uses red, yellow, and green lights. Different colors and their breathing frequencies indicate the status of the submitted documents. A flashing red light indicates the documents are under review, meaning the device is processing the uploaded materials, and the user needs to wait patiently for the result. A solid green light indicates the documents have passed review, meaning they meet the requirements, and the user can continue with subsequent operations. A flashing yellow light indicates the documents need correction, meaning there are some non-compliant parts that require modification or supplementation. In this way, users can quickly understand the review progress by observing the color changes and breathing frequency of the light strip, without needing to constantly monitor the device's detailed interface, thus improving operational convenience.
[0058] Specifically, the bone conduction speaker, located at the top of the terminal device, utilizes bone conduction technology, a method of transmitting sound waves by converting sound into mechanical vibrations of different frequencies. These vibrations are transmitted through the skull, bony labyrinth, inner ear fluid, cochlea, auditory nerve, and auditory center. This speaker uses bone conduction technology to transmit voice prompts directly to the user's inner ear. It can also automatically adjust the volume according to ambient noise, with an error margin of ±3dB. For example, in a noisy office environment, the speaker will automatically increase the volume to ensure the user can clearly hear voice prompts such as "Documents have been uploaded and are under review"; while in a quiet environment, the speaker will appropriately decrease the volume to avoid disturbing the user.
[0059] Furthermore, to ensure that visually impaired users can operate the contractor data review terminal independently, conveniently, and accurately, achieving barrier-free information interaction and functional use, this invention also proposes a Braille operation panel located on the right side of the terminal device. This panel includes eight raised buttons, the shape and arrangement of which conform to Braille standards. Visually impaired users can identify different functions by touching the buttons. The button surface can be coated with an antibacterial coating, a material that inhibits bacterial growth and reproduction, effectively preventing bacterial growth on the button surface and ensuring hygienic operation, especially in equipment used in public places. Here, the buttons incorporate a built-in pressure sensor (selectable with an accuracy of 0.5N). When the user presses a button, the pressure sensor detects the pressure change; when the pressure reaches 0.5N, the corresponding operation is triggered, avoiding inconvenience caused by misoperation.
[0060] Here, vibration feedback is also triggered when the user presses a button. The vibration feedback module is part of the multimodal guidance component and works in conjunction with the Braille control panel. When the pressure sensor in the raised button of the Braille control panel is triggered, the vibration feedback module immediately activates and generates vibration feedback. This vibration feedback is a tactile signal that allows the user to more intuitively feel the effectiveness of the button operation. For example, when a visually impaired user presses a button on the Braille control panel, the vibration feedback module generates a low-frequency (e.g., 20Hz) vibration. The user feels the vibration in their hand and knows that the button has been successfully pressed. Simultaneously, with the voice announcement from the bone conduction speaker, such as "Audit function selected," the user can more accurately understand the result of their operation, further improving the accuracy and convenience of fully blind operation.
[0061] For example, the intelligent contractor document review terminal device proposed in this utility model can be divided into a document upload stage, an intelligent review stage, and a result output stage. In the document upload stage, contractors can insert paper documents through the document input port 60 and scan them using an RGB color scanner, or switch to IC card mode using the replaceable scanning module 10 to read electronic qualifications. The adaptive touch display screen 20 will show a document type selection interface, supporting multiple methods such as photo upload and QR code upload. The pressure sensor at the input port triggers the scanning module to start, completing document digitization in a short time and ensuring high-quality document acquisition. After document digitization, the intelligent review stage begins. The digitized documents are encrypted by a dual-level data encryption module 40 and transmitted to the intelligent review module 30 via a dedicated bus. This module automatically identifies the document type, such as a business license or safety production license, and calls the corresponding review rules. For example, the business license validity period verification rule is that the current date ≤ the expiration date. The review result (pass / correction / fail) can be output in a short time (e.g., within five seconds). Abnormal items will be highlighted in red, such as "qualification certificate expired," allowing users to quickly locate problems.
[0062] Furthermore, during the results output stage, the audit results will be displayed in real time on the adaptive touch display screen 20. Users can select "Print Report" on the adaptive touch display screen 20, and the report content can include audit conclusions and details of anomalies; or they can select "Scan to Download," and the system will generate an encrypted QR code or encrypted link, valid for 12 hours or 24 hours. The invoice printing module 50 will complete the report printing output. If a paper jam occurs at this time, it will automatically reverse the paper and indicate the fault location through the adaptive touch display screen 20, such as "Paper jam at print exit, please remove page 3 of the document," providing users with convenient troubleshooting guidance.
[0063] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
