Description

Technical Field

[0001] This invention relates to the field of security equipment technology, and in particular to a shielded cabinet for wireless charging mobile phones with facial recognition. Background Technology

[0002] With the increasing demands for information security and confidentiality, mobile phone shielding cabinets have become standard security equipment in government agencies, classified research institutes, standardized examination rooms, military enterprises, and confidential meeting venues. Their core function is to block the transmission of communication signals between mobile phones and the outside world through electromagnetic shielding structures, thereby preventing mobile phone leaks, illegal communications, and cheating by electronic devices. They are key hardware facilities for implementing confidentiality management regulations and maintaining order in venues.

[0003] Existing mobile phone shielding cabinets are mostly constructed with pure metal cabinets and mechanical locks. Some upgraded products use IC card or ID card swiping unlocking methods. Although they can meet the basic needs of mobile phone storage and signal shielding, there are still many technical defects and pain points in actual application.

[0004] First, the identity verification mechanism has obvious management loopholes and insufficient rigor in confidentiality control. Traditional mechanical locks rely on physical keys to open and close cabinet doors, which are generally prone to key loss and duplication, unclear management responsibilities, and are highly susceptible to unauthorized access and unauthorized opening. Furthermore, it is impossible to accurately trace the identity of the person accessing the lock and the time of operation, which does not meet the confidentiality management requirements of "person-to-person and full traceability" in classified locations. Although card-swipe unlocking is an improvement over mechanical locks, the card itself is also at risk of loss, lending, and theft. Identity verification only verifies the card, not the person, and cannot fundamentally prevent unauthorized opening and impersonation. The control measures are insufficient to meet the standards of high-level confidentiality scenarios.

[0005] Secondly, the equipment has limited functionality and cannot meet the needs of smartphone users, thus restricting its practicality. Existing mobile phone shielding cabinets only provide electromagnetic shielding and storage functions, completely neglecting the issue of battery replenishment during phone storage. Smartphones are used frequently and have high battery life requirements. When personnel enter confidential areas to store their phones, they often have limited remaining battery power. After prolonged storage, phones frequently fail to power up or shut down automatically, directly impacting subsequent work communications and equipment use, resulting in a poor user experience. If external charging cables are installed through openings in the shielding cabinet to address the charging issue, it would directly compromise the integrity of the cabinet's electromagnetic shielding, causing signal leakage and significantly reducing shielding effectiveness, violating the core design purpose of the shielding cabinet. Furthermore, exposed charging cables pose safety hazards such as messy wiring, short circuits from pulling, dust accumulation, and water ingress, making them unsuitable for compliant use in confidential locations.

[0006] Furthermore, the equipment has a low level of intelligence and low management efficiency, making it difficult to match the development trend of smart security. Most traditional mobile phone shielding cabinets operate offline and independently, lacking network management capabilities. Personnel access registration relies on manual paper records, which is not only inefficient and prone to errors and omissions, but also makes it difficult to store data for the long term and quickly trace it. Managers cannot remotely configure personnel permissions in batches, monitor the cabinet's operating status and compartment occupancy in real time, or receive timely alarms for abnormal events. The management and maintenance costs are high, making it unsuitable for the current industry upgrade direction of smart security and digital security.

[0007] In addition, the emergency protection mechanisms of existing shielded cabinets are generally inadequate. When encountering emergencies such as power outages or electrical control system failures, it is often impossible to open the cabinet and retrieve the equipment normally, which affects the normal work arrangements of personnel. Moreover, most products lack intuitive compartment status indicators, making it impossible for users to quickly identify available compartments and charging status, and there is still considerable room for improvement in ease of use. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a face recognition wireless charging mobile phone shielding cabinet.

[0009] One of the objectives of this invention is achieved through the following technical solution: A shielding cabinet for wireless charging mobile phones with facial recognition includes a cabinet body. The interior of the cabinet body is divided into several independent shielding compartments, each equipped with an openable and closable door. The cabinet body and the closed compartment doors together form a closed cavity with electromagnetic signal shielding function. The front of the cabinet is equipped with a facial recognition module. The cabinet interior integrates a control unit and several sets of electronic locks. The facial recognition module is electrically connected to the control unit. Each set of electronic locks is set one-to-one with each shielded compartment to lock the corresponding compartment door. The control unit pre-stores the facial feature information of authorized personnel and the compartment permission mapping relationship. It is used to receive facial images collected by the facial recognition module and complete identity comparison. After the identity verification is passed, it controls the electronic locks within the corresponding authorized range to unlock, and at the same time generates and stores the record information of this access operation. Each of the shielded compartments is equipped with a wireless charging module. The wireless charging module is electrically connected to the power supply line inside the cabinet through a shielded wiring structure with electromagnetic filtering function. The charging emitter of the wireless charging module is attached to the inner wall surface of the shielded compartment, and the installation point of the wireless charging module is separated from the electromagnetic shielding sealing structure of the compartment. Under the premise of maintaining the integrity of the electromagnetic shielding of the shielded compartment and not reducing the shielding effectiveness, it provides wireless charging for the smartphone placed in the compartment.

[0010] Furthermore, the wireless charging module is embedded in the bottom inner wall of the shielding grid, the inner wall of the shielding grid is a continuous metal shielding layer, and the outer side of the charging transmitting surface of the wireless charging module is covered with a non-metallic wave-transparent protective panel. The edge of the non-metallic wave-transparent protective panel is seamlessly sealed to the surrounding metal shielding layer to maintain the conductive continuity and electromagnetic shielding performance of the inner wall of the shielding grid.

[0011] Furthermore, the face recognition module integrates a liveness detection subunit, which is used to perform liveness verification during the face image acquisition process to identify non-live forgery media such as photos, videos, and masks; the control unit is also equipped with a permission configuration module, which supports assigning different numbers and different numbers of shielded grid usage permissions to different authorized personnel, realizing one-to-one or one-to-many permission binding between personnel and grids.

[0012] Furthermore, the control unit is communicatively connected to each wireless charging module, and each wireless charging module is equipped with a foreign object detection unit and a power identification unit. The foreign object detection unit is used to detect whether there are any metal foreign objects in the shielded slot. When a foreign object is detected, the charging output is stopped and a prompt is triggered. The power identification unit is used to identify the power status of the device to be charged and automatically disconnects the charging output after the device is fully charged.

[0013] Furthermore, a beryllium copper conductive shielding strip is provided at the mating frame of the compartment door and the cabinet body. When the compartment door is closed, the beryllium copper conductive shielding strip is tightly pressed against the metal frame of the cabinet body to form a continuously conductive electromagnetic sealing ring. Each shielded compartment is separated from each other by a metal partition, so that each shielded compartment forms an independent electromagnetic shielding space.

[0014] Furthermore, each shielded compartment on the front of the cabinet is equipped with a status indicator light. The status indicator light is electrically connected to the control unit and is used to indicate the idle / occupied, charging / charging complete, and locked / unlocked status of the corresponding compartment through different light colors and on / off states. The side of the face recognition module is also equipped with an operation prompt area to display the verification status and operation instructions.

[0015] Furthermore, the control unit has a built-in local storage module and a wired / wireless networking module. The local storage module is used to persistently store face verification logs, grid switch records, charging operation data, and abnormal event records. The wired / wireless networking module is used to synchronously upload local records to the remote management platform and receive permission updates, parameter settings, and operation control commands issued by the remote management platform.

[0016] Furthermore, the cabinet is also equipped with a mechanical emergency lock assembly and an emergency power supply interface. The mechanical emergency lock assembly is mechanically linked to each compartment door and is used to manually open the corresponding compartment door when the electrical control system loses power or malfunctions. The emergency power supply interface is used to connect an external backup power source to provide emergency working power for the face recognition module, control unit, and electronic lock when the external mains power is interrupted.

[0017] Furthermore, the wireless charging module is compatible with the Qi standard wireless charging protocol, and the output power supports adaptive adjustment from 5W to 15W. The control unit can automatically match the optimal charging power according to the charging protocol of the connected smartphone. The non-metallic wave-transparent protective panel is made of tempered glass or high-strength insulating resin, and its surface is flush with the inner wall of the shielding grid and has wear-resistant and scratch-resistant properties.

[0018] Furthermore, the remote management platform has functions such as personnel access control, access record tracing, charging status monitoring, and abnormal alarm push. When abnormal scenarios such as continuous unauthorized face verification failure, abnormal opening of the grid, charging failure, or power failure occur, the control unit pushes alarm information to the remote management platform in real time through the wired / wireless network module.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: First, this invention employs a high-precision facial recognition module combined with binocular liveness detection technology, using personnel biometrics as the sole basis for identity verification. This fundamentally eliminates management loopholes caused by the loss, lending, or misuse of keys, cards, or other media, effectively preventing unauthorized access and other violations. Combined with the control unit's permission mapping mechanism, it allows for flexible one-to-one or one-to-many permission binding between personnel and storage compartments, adapting to the needs of different levels of personnel. Simultaneously, all access operations automatically record personnel identity, operation time, and compartment number, ensuring full traceability and fully complying with the confidentiality management requirements of "clear responsibilities and complete record-keeping" in classified locations, significantly enhancing the security level and control rigor of the equipment.

[0020] Secondly, this invention embeds an integrated wireless charging module within each independent shielded compartment. A shielded wiring structure with electromagnetic filtering achieves a smooth shielding transition for the power supply lines. Furthermore, a seamless seal between the non-metallic wave-transparent protective panel and the metal shielding wall ensures unobstructed wireless charging for stored smartphones without disrupting the conductive continuity of the shielded compartments or reducing electromagnetic shielding effectiveness. This completely resolves the technical contradictions of traditional shielded cabinets, where charging is impossible and external charging cables compromise shielding performance. The device eliminates the need for external charging cables, avoiding safety hazards such as messy wiring, short circuits, and fires. The compartments are clean and tidy, ensuring sufficient power for users to retrieve their phones, significantly improving the device's practicality and user experience.

[0021] Third, the control unit of this invention integrates local storage and network communication modules, enabling it to connect to a remote management platform. This allows for remote configuration of personnel permissions, batch tracing of storage and retrieval records, real-time monitoring of charging status, and proactive alarms for abnormal events. It replaces the traditional manual registration management model, ensuring accurate and traceable data that is retained long-term. Management personnel can remotely perform batch maintenance and risk management, significantly improving management efficiency and aligning with the industry trends of smart security and digital security. Simultaneously, the multi-status indicator lights on the charging bay provide intuitive feedback on bay occupancy, charging progress, and fault status, reducing the learning curve and operational threshold for users.

[0022] Fourth, each shielding compartment of this invention adopts an independent metal cavity structure, combined with a full-circumference beryllium copper conductive shielding strip, to ensure high shielding efficiency over a wide frequency band and meet national confidentiality standards. The wireless charging module integrates foreign object detection and power identification functions, which can automatically avoid the risk of overheating from metal foreign objects. After the battery is fully charged, it automatically switches to trickle charging mode, balancing charging safety and battery life. In addition, the device is equipped with a mechanical emergency lock group and an emergency power supply interface, which can ensure normal access to mobile phones in extreme scenarios such as power outages and electrical control failures. The device has strong fault tolerance and emergency support capabilities, and can be stably adapted to various high-requirement application scenarios such as government agencies, examination rooms, and military enterprises. It has the ability to completely replace traditional mobile phone shielding cabinets, and its market promotion and industrial application value are outstanding.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] I. Overall Cabinet and Electromagnetic Shielding Structure Cabinet 1 is constructed from 1.2mm thick high-quality cold-rolled steel sheet, CNC bent and integrally welded, with an outer surface treated with electrostatic powder coating for corrosion protection. It features a vertical cabinet structure with standard dimensions of 1800mm height, 800mm width, and 450mm depth. The number of compartments and overall dimensions can be adjusted to suit different scenarios such as confidential locations and examination rooms. The interior of Cabinet 1 is divided into 24 independent shielded compartments 2 by vertical and horizontal metal partitions. Each compartment measures 180mm × 100mm × 200mm, accommodating the flat storage of mainstream smartphones up to 6.7 inches in size. All metal partitions and the inner wall of Cabinet 1 are a continuous conductive metal structure, ensuring no electromagnetic interference between the shielded compartments 2, each forming an independent Faraday shielding cavity.

[0030] Each shielding compartment 2 has a compartment door 3 hinged to its front opening via a damping hinge. The compartment door 3 is also made of metal sheet, and its four-sided frame, which mates with the cabinet body 1, is inlaid with a beryllium copper conductive shielding strip 10. In this embodiment, the beryllium copper conductive shielding strip 10 is made of 0.8mm thick tin-plated beryllium copper spring sheet, which is continuously and fully distributed along the frame of the compartment door 3 without any splicing or breaks. When the compartment door 3 is closed and locked, the beryllium copper conductive shielding strip 10 is tightly pressed against the metal door frame of the cabinet body 1 to form a full-circumference conductive sealing ring, ensuring that the electromagnetic shielding effectiveness of the shielding compartment 2 is ≥65dB in the 10MHz~3GHz frequency band, meeting the effectiveness requirements of mobile phone shielding cabinets in the national security standards, and can completely shield various mobile phone communication signals such as 2G / 3G / 4G / 5G, WiFi, and Bluetooth.

[0031] II. Facial Recognition Intelligent Lock Control System A face recognition module 4 is embedded in the center of the upper front of cabinet 1. In this embodiment, the face recognition module 4 adopts an FM210 binocular face recognition module, equipped with a 2-megapixel RGB camera and an infrared supplementary light camera. It has a built-in binocular liveness detection algorithm, which can effectively identify non-liveness spoofing attacks such as paper photos, electronic screens, and 3D masks. The recognition distance covers 0.3m~1.2m, the single recognition response time is ≤0.5s, and it can still recognize stably in low light environments. The face recognition module 4 is electrically connected to the control unit 5 in the electrical compartment at the top of cabinet 1 through a shielded signal cable, and transmits the collected face image data to the control unit 5 in real time for comparison processing.

[0032] The control unit 5 is fixedly installed in an independent electrical compartment at the top of cabinet 1. The main control chip is an STM32F407ZGT6 industrial-grade microcontroller, with integrated facial feature comparison algorithms, access control logic, and lock drive circuitry. It operates within a temperature range of -20℃ to 60℃, adapting to various indoor and outdoor scenarios. The control unit 5 pre-stores a database of authorized personnel's facial features, as well as an access mapping relationship between personnel identities and the numbers of shielded compartments 2. It supports flexible one-to-one and one-to-many access control configurations, allowing for the allocation of individual compartments to ordinary personnel or the allocation of access to all compartments to management personnel, meeting the needs of hierarchical management.

[0033] Each shielded compartment 2 is equipped with a set of electrically controlled locks 6. The electrically controlled locks 6 adopt a DC12V small electromagnetic latch structure and are fixedly installed on the inner door frame of the compartment. When the latch extends, it engages with the latch of the compartment door 3 to achieve reliable locking. The anti-pry performance meets the security equipment standards. Each set of electrically controlled locks 6 is electrically connected to the control unit 5 and is uniformly driven and controlled by the control unit 5. When the control unit 5 verifies the facial information and confirms that the person has the corresponding compartment access, it outputs a drive signal to retract the latch of the corresponding electrically controlled lock 6. The compartment door 3 automatically opens with the help of the damping hinge. At the same time, the control unit 5 automatically records the personnel information, operation time, compartment number and operation type of this operation and stores it in the local operation log.

[0034] Each shielded compartment 2 on the front of the cabinet 1 is equipped with a status indicator light 11 embedded above it. The status indicator light 11 uses RGB three-color LED beads and is electrically connected to the control unit 5. The status of the compartment is intuitively reflected by different light states: a solid green light is displayed when the compartment is idle and available; a solid blue light is displayed when the compartment is occupied and charging is in progress; a green light flashes slowly when the mobile phone is fully charged; and a red light flashes rapidly when the compartment is abnormal or there is a charging failure. This makes it easy for users and managers to quickly identify the status of the equipment.

[0035] III. Embedded Wireless Charging System Each shielded compartment 2 has a wireless charging module 7 embedded in its bottom inner wall. In this embodiment, the wireless charging module 7 adopts a Qi 1.3 standard wireless charging transmission scheme based on the IP6806 main control chip, supporting four power adaptive adjustments of 5W, 7.5W, 10W, and 15W. It is compatible with the wireless charging protocols of mainstream smartphone brands such as Apple and Android, and can automatically identify the device protocol and match the optimal charging power. The charging transmission coil of the wireless charging module 7 is arranged horizontally, with the transmitting surface facing upwards and directly towards the inside of the compartment. The back of the phone can be placed flat to fit against the charging area.

[0036] The bottom metal wall of the shielding grid 2 has an adapter mounting hole corresponding to the position of the wireless charging module 7. The wireless charging module 7 is embedded in the hole, and its transmitting surface is covered with a non-metallic wave-transparent protective panel 9. The non-metallic wave-transparent protective panel 9 is made of 3mm thick high-strength tempered glass with a wireless signal transmittance of ≥90%. The surface is treated with anti-scratch, wear-resistant and anti-slip treatment. The panel is seamlessly bonded to the surrounding metal shielding wall with conductive sealant around its perimeter. This ensures the normal penetration and transmission of the wireless charging magnetic field while maintaining the conductivity continuity of the inner wall of the shielding grid 2. It avoids the destruction of electromagnetic shielding effectiveness due to structural openings, thus structurally resolving the conflict between charging function and shielding performance.

[0037] The power supply line of the wireless charging module 7 needs to pass through the metal wall of the shielded compartment to connect to the main power supply circuit of the cabinet. A shielded wiring structure 8 with electromagnetic filtering function is installed here. In this embodiment, the shielded wiring structure 8 adopts an MF-02 type feedthrough capacitor filter component with a built-in multi-level LC filter network, which attenuates electromagnetic interference in the 10kHz~1GHz frequency band by ≥40dB. The power supply line passes through the metal shielded wall through the feedthrough capacitor, which not only realizes the stable transmission of DC power, but also blocks the electromagnetic signal from leaking into or out of the cabinet through the line gaps, ensuring that the overall shielding performance of the shielded compartment is not affected by the power supply line.

[0038] Each wireless charging module 7 integrates a foreign object detection unit and a power identification unit. The foreign object detection unit, based on the Q-value detection principle, can accurately identify metallic foreign objects such as coins, keys, and metal jewelry within the charging slot. When a foreign object is detected, charging output is immediately stopped, and a corresponding status indicator 11 flashes red to indicate this, preventing the metallic foreign object from heating up in the alternating magnetic field and causing safety hazards. The power identification unit can interactively identify the phone's battery status via the charging protocol. When the phone is fully charged to 100%, it automatically cuts off high-power charging output and enters a low-power trickle charging mode, ensuring sufficient power for the phone when it is used while preventing damage from prolonged overcharging.

[0039] IV. Network Management and Emergency Response Function Module The control unit 5 has a built-in local storage module and a network communication module: The local storage module uses a 32GB industrial-grade Flash storage chip, which can store no less than 100,000 facial verification records, grid switch records, and charging operation data. The data is not lost when power is off, meeting the needs of long-term traceability; The network communication module integrates a W5500 Ethernet chip and an ESP8266 WiFi module, supporting wired and wireless dual network modes. It can synchronously upload local operation data to the remote management platform, and at the same time receive remote commands issued by the platform, such as adding / deleting personnel permissions, setting charging parameters, and upgrading system firmware.

[0040] The remote management platform can be deployed on a cloud server or a local computer room, and has four core functions: personnel access management, access record tracing and querying, real-time monitoring of charging status, and abnormal alarm push notifications. When abnormal events such as five consecutive failed face verifications, abnormal opening of the charging slot, charging failure, or power outage occur, the control unit 5 immediately pushes alarm information to the management platform through the network module, and simultaneously triggers local audio and visual prompts, facilitating immediate response by management personnel and achieving intelligent control across all scenarios.

[0041] The side of cabinet 1 is equipped with a mechanical emergency lock assembly 12 and an emergency power supply interface 13. The mechanical emergency lock assembly 12 contains a dedicated lock cylinder corresponding to each shielded compartment 2 and is equipped with a management-level dedicated key. When the power control system fails or the hardware fails and cannot be unlocked electrically, the corresponding compartment door 3 can be manually opened with the mechanical key to ensure that the mobile phone can be used normally in extreme scenarios. The emergency power supply interface 13 adopts a standard DC12V DC interface and can be connected to an external mobile backup power supply. When the mains power is interrupted, it provides emergency working power for the face recognition module 4, control unit 5 and electric lock 6 to maintain basic identity verification and unlocking functions.

[0042] V. Equipment Working Principle When storing a mobile phone, the user stands in the front recognition area of ​​cabinet 1, facing the face recognition module 4. The face recognition module 4 automatically captures the facial image and completes the liveness verification, transmitting the facial feature data to the control unit 5. The control unit 5 retrieves the pre-stored facial feature database for feature comparison. After confirming that the user's identity is legitimate and that they have the corresponding access rights to the compartment, it outputs a drive signal to unlock the corresponding electronic lock 6, and the compartment door 3 automatically pops open. The user places the mobile phone screen-up, back against the non-metallic wave-transparent protective panel 9, and smoothly into the shielded compartment 2. The user then manually closes the compartment door 3, and the electronic lock 6 automatically locks. At this time, the wireless charging module 7 detects the charging load and automatically starts the wireless charging function. The corresponding status indicator 11 switches to a solid blue light. The control unit 5 simultaneously records the personnel, time, and compartment number information of this storage operation, generating a storage log.

[0043] When retrieving the phone, the user completes face collection and identity verification through the face recognition module 4. After successful verification, the control unit 5 unlocks the electronic lock 6 of the corresponding compartment, and the compartment door 3 pops open. After the user retrieves the phone, they manually close the compartment door 3, and the electronic lock 6 automatically locks. The wireless charging module 7 detects the removal of the load and stops charging output. The status indicator light 11 returns to a solid green. The control unit 5 records the retrieval operation log, completing a full storage and retrieval process.

[0044] Throughout the charging process, the wireless charging module 7 continuously monitors the load status and foreign object detection. If a metal object is detected, the charging output is immediately cut off and an alarm light is triggered. After the object is removed, it automatically returns to standby mode. Once the phone is fully charged, it automatically switches to trickle charging mode, balancing battery life and endurance. All operation records, charging data, and device status are synchronized to a remote management platform in real time. Administrators can remotely manage permissions in batches, trace personnel access records, and monitor device operation status through the platform. This achieves integrated operation of confidentiality control, intelligent verification, and battery replenishment, completely replacing traditional single-function phone shielding cabinets.
