Technical Field

[0001] The present invention relates to the field of intelligent filing cabinets, and in particular to an intelligent filing cabinet and a management method thereof. Background Art

[0002] As metrology and calibration laboratories continue to increase their requirements for test data traceability, quality system compliance, and audit preparation, the traditional manual file management model can no longer meet the laboratory's needs for efficient management of massive files. The complexity of laboratory files (such as the coexistence of paper and electronic data, and the mixing of multi-source files), strict compliance requirements (such as CNAS, JJG and other standards), and the need for rapid retrieval of historical data during audits have become key bottlenecks restricting laboratory operating efficiency and quality assurance. Equipment verification records, interim verification reports, original data, calibration certificates, etc. need to be preserved for a long time, and paper files are prone to aging, while electronic files have problems such as outdated formats and poor system compatibility.

[0003] In order to adapt to the process of informatization, smart filing cabinets have been increasingly popularized and applied. Smart filing cabinets usually use high-frequency RFID technology, which can identify high-frequency RFID tags in the cabinet to accurately locate each file box. They support multiple identity authentication methods such as fingerprints, card swiping, passwords, and faces. Electronic locks control the opening and closing of doors, and achieve seamless docking with the marketing system to realize the functions of shelving and locating files to the grid, removing files from the shelves and automatically clearing the location, automatic inventory function, automatic LED light reminder for file retrieval, reminder of wrong file location, reminder of file expiration, operation process backtracking, multi-cabinet linkage, multi-level authority management, etc.

[0041] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0042] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0043] Reference Figures 1 to 3, this embodiment provides an intelligent filing cabinet, comprising a cabinet body 1, including a plurality of equipment cavities 11 and filing cavities 12 opened on an end surface thereof, and a cabinet door 13 for closing the filing cavities 12;

[0044] An air inlet assembly 21 and an air outlet assembly 22 are provided in the equipment cavity 11;

[0045] The inside of the equipment cavity 11 is also provided with a temperature control component 31 and a refrigeration component 32 for circulating a coolant into the temperature control component 31;

[0046] The archive chamber 12 is connected to the equipment chamber 11, and air is transported from the equipment chamber 11 to the archive chamber 12 for temperature control.

[0047] As an optional embodiment, the air intake assembly 21 includes an air intake branch pipe 211 connected to the archive chamber 12; a stop valve 212 is provided on the air intake branch pipe 211, and a driven wheel 213 for controlling the on-off of the stop valve 212 is provided on the stop valve 212;

[0048] The air outlet assembly 22 includes an air outlet branch pipe 221 communicating with the archive chamber 12 .

[0049] In this embodiment, the cabinet 1 is constructed of metal and equipped with a variety of intelligent devices, including a surveillance camera, facial recognition, fingerprint recognition, a widescreen touchscreen display, a QR code scanner, a high-frequency card reader, a keyboard and mouse operation platform, and a QR code sticker printer, to efficiently support file management. The cabinet 1 is equipped with multiple chambers, specifically one equipment chamber 11 and ten file chambers 12. The equipment chamber 11 is used to accommodate and install relevant electronic equipment and temperature control components; the file chambers 12 are used to store file boxes containing paper files.

[0050] An air intake assembly 21 and an air outlet assembly 22 are located within the equipment chamber 11 to facilitate air circulation. A driven fan is installed within the air intake assembly 21, drawing in external air or air from within the equipment chamber and delivering it to each archive chamber 12. The air intake assembly 21 is connected to each archive chamber 12 via air intake manifolds 211. Each air intake manifold 211 is equipped with a shutoff valve 212 for controlling air flow. The shutoff valves 212 are also equipped with a driven pulley 213, enabling automated control.

[0051] The air outlet assembly 22 is also connected to each file cavity 12 , and discharges the air heated by the electronic equipment in the file cavity out of the cabinet through the air outlet branch pipe 221 , thereby forming an effective air circulation path.

[0052] Furthermore, a temperature control assembly 31 and a refrigeration assembly 32 are provided within the equipment chamber 11. The refrigeration assembly 32 circulates coolant to the temperature control assembly, thereby cooling the air entering the archive chamber 12. As a result, the air delivered from the equipment chamber 11 to the archive chamber 12 is cooled and low-temperature air, which helps lower the ambient temperature of the archive storage environment and prevents damage to paper archives caused by high temperatures, thereby effectively extending the service life of the archive boxes and the archives themselves.

[0053] In summary, this device not only has the functions of file positioning, identity authentication, permission management, automatic inventory, etc. that traditional smart filing cabinets have, but also solves the problem of excessively high file storage environment temperature due to continuous heating of electronic equipment in the existing technology through an integrated temperature control system, thereby improving the security and reliability of long-term file storage.

[0054] Reference Figure 2 and Figure 3 A temperature control assembly 31 is provided within the equipment chamber 11. Specifically, the temperature control assembly 31 is a temperature control box with an open top. A horizontally positioned temperature sensing tube 311 is provided within the temperature control assembly 31. The ends of the temperature sensing tube 311 are connected to the air inlet assembly 21 and the air outlet assembly 22, respectively. Driven by a fan, air circulates continuously along the air inlet assembly 21, the archive chamber 12, the air outlet assembly 22, and the temperature sensing tube 311, achieving continuous exchange of air between the temperature sensing tube 311 and the archive chamber 12. A refrigeration assembly 32 is installed within the equipment chamber 11 to circulate coolant into the temperature control assembly 31, thereby lowering the temperature of the air passing through the temperature sensing tube 311.

[0055] Reference Figure 4 In some embodiments, the temperature regulating assembly 31 includes a temperature sensing tube 311 disposed inside the temperature regulating assembly 31;

[0056] The temperature sensing tube 311 is in a spiral shape as a whole.

[0057] In this embodiment, the temperature sensing tube 311 is spirally shaped as a whole, which increases the contact area between the temperature sensing tube 311 and the coolant and the contact area between the air and the temperature sensing tube 311, thereby helping to improve the heat exchange efficiency and thus improve the cooling efficiency.

[0058] Reference Figure 2 and Figure 3 In some embodiments, the refrigeration assembly 32 includes a cooling machine 321, a water storage tank 322 disposed on one side of the cooling machine 321, and a water return pipe 323 disposed on one side of the water storage tank 322;

[0059] The water inlet pipe of the cooling machine 321 extends into the water storage tank 322 , the water outlet pipe of the cooling machine 321 is connected to the temperature adjustment component 31 , and both ends of the return pipe 323 are connected to the temperature adjustment component 31 and the water storage tank 322 respectively.

[0060] In this embodiment, the refrigeration assembly 32 includes a chiller 321, a water tank 322, and a return pipe 323. The chiller 321 is installed within the equipment cavity 11 and is used to cool the coolant. The chiller 321 has an inlet pipe and an outlet pipe. The inlet pipe extends into the water tank 322 and is used to draw cooling water from the tank. The outlet pipe is connected to the temperature control assembly 31 and delivers the cooling water, which has been cooled by the chiller 321, to the temperature control assembly 31.

[0061] Preferably, the two ends of the return pipe 323 are connected to the thermostat assembly 31 and the water tank 322, respectively, forming a cooling water circulation loop. It is worth noting that the connection point between the return pipe 323 and the water tank 322 is higher than the connection point between the outlet pipe of the chiller 321 and the water tank 322. This design facilitates the smooth return of cooling water to the water tank under the action of gravity, thereby improving system operating efficiency.

[0062] During operation, the cooling water in the water tank 322 is cooled by the cooling machine 321 and then transported to the temperature control assembly 31. Within the temperature control assembly 31, the cooling water exchanges heat with the temperature sensing tube 311, absorbing heat and increasing its temperature. The water then returns to the water tank 322 through the return pipe 323, completing a cooling cycle. The cooling water continuously circulates under the action of the cooling machine 321, thereby achieving continuous cooling control of the air within the archive chamber 12.

[0063] The refrigeration structure is reasonably designed and the cooling cycle is stable and reliable. It can effectively reduce the heat generated by the continuous operation of electronic equipment inside the smart filing cabinet, provide a constant and suitable storage environment for paper files, and further extend the storage life of the files.

[0064] Reference Figure 4 In some embodiments, the air intake assembly 21 includes an air intake branch pipe 211 connected to the archive chamber 12; the air intake branch pipe 211 is provided with a stop valve 212, and the stop valve 212 is provided with a driven wheel 213 for controlling on and off;

[0065] The air outlet assembly 22 includes an air outlet branch pipe 221 connected to the archive chamber 12.

[0066] As an optional embodiment, the temperature control component 31 includes a temperature sensing tube 312 fixedly arranged on one side of the side wall thereof. One end of the temperature sensing tube 312 is open and located inside the temperature control component 31. The temperature sensing tube 312 is in communication with the outside of the temperature control component 31.

[0067] A piston 3121 is slidably connected to the interior of the temperature sensing tube 312 , and mercury is filled between the piston 3121 and the bottom wall of the temperature sensing tube 312 ; a temperature regulating rack 3122 is fixedly connected to the end of the piston 3121 away from the mercury.

[0068] As an optional embodiment, the cabinet door 13 includes a door body 131, a rotating shaft 132 penetrating the side wall of the door body 131, a driving wheel 133 fixedly disposed on the axis of the rotating shaft 132, and a synchronous belt 134 disposed between the driving wheel 133 and the driven wheel 213;

[0069] When the cabinet door 13 is in the fully open state, the stop valve 212 is in the closed state;

[0070] When the cabinet door 13 is in a fully closed state, the stop valve 212 is in an open state.

[0071] In this embodiment, the temperature within the archive chamber 12 is also affected by the room temperature, resulting in certain fluctuations that affect the archive storage environment. A temperature-sensing cylinder 312 is fixedly connected to the side wall of the temperature-regulating assembly 31. The temperature-sensing cylinder 312 is generally hollow cylindrical with one end open and located within the temperature-regulating assembly 31. The temperature-sensing cylinder 312 is connected to the outside of the temperature-regulating assembly 31. A piston 3121 is slidably connected within the temperature-sensing cylinder 312. Mercury is filled between the piston 3121 and the bottom wall of the temperature-sensing cylinder 312. To prevent mercury leakage, a seal is formed between the piston 3121 and the inner wall of the temperature-sensing cylinder 312. A thermostatic rack 3122 is fixedly connected to the end of the piston 3121 facing away from the mercury. A flow control valve 3211 is mounted on the water outlet pipe of the cooler 321. This flow control valve 3211 is equipped with a thermostatic gear 3212 for controlling the opening and closing of the flow control valve 3211. The thermostatic gear 3212 meshes with the thermostatic rack 3122. When the coolant temperature within the thermostatic assembly 31 rises, the mercury expands and drives the piston 3121 and the thermostatic rack 3122 to move, causing the thermostatic rack 3122 to rotate in a direction that increases the opening and closing of the flow control valve 3211, thereby increasing the cooling capacity. When the coolant temperature within the thermostatic assembly 31 decreases, the mercury contracts and drives the piston 3121 and the thermostatic rack 3122 to move in the opposite direction, causing the thermostatic rack 3122 to rotate in a direction that decreases the opening and closing of the flow control valve 3211, thereby reducing the cooling capacity. This achieves automatic regulation of the cooling water flow rate in response to temperature changes.

[0072] Preferably, when the cabinet door 13 is opened, the corresponding file chamber 12 is connected to the outside environment. At this time, the air intake branch pipe 211 continues to output low-temperature air, which will cause a certain amount of waste. The air intake branch pipe 211 is installed with a stop valve 212, and the stop valve 212 is equipped with a driven wheel 213 for controlling the opening and closing of the stop valve 212. When the cabinet door 13 is opened, the stop valve 212 is closed to prevent the continued output of low-temperature air, thereby avoiding waste of low-temperature air and saving energy.

[0073] The cabinet body 1 is provided with a cabinet door 13 for closing the filing chamber 12. The cabinet door 13 includes a door body 131 and a rotating shaft 132. A driving wheel 133 is coaxially fixedly connected to the rotating shaft 132. The operator manually controls the stop valve 212, which increases the operating steps and workload. A synchronous belt 134 is provided between the driven wheel 213 and the driving wheel 133. When the cabinet door 13 is in a fully closed state, the stop valve 212 is in an open state for normal cooling. When the cabinet door 13 is opened, the rotating shaft 132 drives the driving wheel 133 to rotate. The driving wheel 133 drives the driven wheel 213 to rotate through the synchronous belt 134, so that the stop valve 212 gradually closes. When the cabinet door 13 is in a fully open state, the stop valve 212 is in a closed state. Linking the opening and closing actions of the cabinet door 13 with the opening and closing actions of the stop valve 212 helps to simplify the operating steps of the management personnel.

[0074] Reference Figure 6 In some embodiments, a dehumidifier 135 for dehumidifying the interior of the archive chamber 12 is provided on the cabinet door 13, and a detection and control circuit is provided on the cabinet door 13, which includes a sensing module 6, a comparison module 7 and a control module 8;

[0075] The sensing module 6 includes a humidity sensor 61, which is disposed on the inner side of the cabinet door 13 and is used to detect the humidity in the file chamber 12 and output a sensing signal;

[0076] The comparison module 7 is electrically connected to the sensing module 6 and is used to receive the sensing signal from the sensing module 6. When the comparison module 7 receives the sensing signal, it compares the voltage value corresponding to the sensing signal with the preset voltage value. If the voltage value of the sensing signal is greater than the preset voltage value, the comparison module 7 outputs a start signal.

[0077] The control module 8 is electrically connected to the comparison module 7 . The control module 8 is configured to receive a start signal from the comparison module 7 . When the control module 8 receives the start signal, it outputs a control signal. The control signal controls the dehumidifier 135 to start.

[0078] In this embodiment, a dehumidifier 135 for dehumidifying the interior of the file chamber 12 is provided on the cabinet door 13. A detection and control circuit is provided on the cabinet door 13. The detection and control circuit includes a sensing module 6, a comparison module 7 and a control module 8;

[0079] The sensing module 6 includes a humidity sensor 61, which is disposed on the inner side of the cabinet door 13 and is used to detect the humidity in the file chamber 12 and output a sensing signal;

[0080] The comparison module 7 is electrically connected to the sensing module 6 and is used to receive the sensing signal from the sensing module 6. When the comparison module 7 receives the sensing signal, it compares the voltage value corresponding to the sensing signal with the preset voltage value. If the voltage value of the sensing signal is greater than the preset voltage value, the comparison module 7 outputs a start signal.

[0081] The control module 8 is electrically connected to the comparison module 7. The control module 8 is used to receive the start signal of the comparison module 7. When the control module 8 receives the start signal, it outputs a control signal. The control signal controls the dehumidifier 135 to start.

[0082] In this embodiment, the detection and control circuit includes a sensing module 6, a comparison module 7 and a control module 8:

[0083] The sensing module 6, a humidity sensor is provided on the inner side of the cabinet door 13, and is used to detect the humidity in the file cavity 12 and output a sensing signal;

[0084] The comparison module 7 includes: a comparator T, wherein the positive input terminal of the comparator T is electrically connected to the output terminal of the humidity sensor; a transistor Q, wherein the base of the transistor Q is electrically connected to the output terminal of the comparator T; a resistor R1, wherein one end of the resistor R1 is electrically connected to the collector of the transistor Q, and the other end of the resistor R1 is electrically connected to the power supply VCC; an electromagnetic coil KA1 of the relay, wherein one end of the electromagnetic coil KA1 of the relay is electrically connected to the emitter of the transistor Q; and a resistor R2, wherein one end of the resistor R2 is electrically connected to the end of the electromagnetic coil KA1 of the relay away from the transistor Q, and the other end of the resistor R2 is grounded.

[0085] The control module 8 includes: a normally-open switch KA1-1 of a relay, one end of which is electrically connected between the electromagnetic coil KA1 of the relay and the resistor R2; a dehumidifier 135 installed on the cabinet door 13 and used to dehumidify the interior of the file chamber 12, one end of the dehumidifier 135 being electrically connected to the end of the normally-open switch KA1-1 of the relay away from the resistor R2; and a resistor R3, one end of the resistor R3 being electrically connected to the end of the dehumidifier 135 away from the normally-open switch KA1-1 of the relay, and the other end of the resistor R3 being grounded.

[0086] Preferably, the humidity sensor senses and detects the humidity in the archive chamber 12 and outputs a sensing signal. The comparison module 7 receives the sensing signal and compares the voltage value of the received sensing signal with a preset voltage value. The preset voltage value corresponds to the voltage value of the maximum value of the standard environmental humidity for archive storage. If the voltage value corresponding to the sensing signal is greater than the preset voltage value, that is, the environmental humidity exceeds the maximum value of the standard environmental humidity for archive storage, a start signal is output. The control module 8 receives the start signal and outputs a control signal. The control signal controls the dehumidifier 135 to start, reduce the humidity in the archive chamber 12, and realize automatic adjustment of the humidity in the archive chamber 12.

[0087] The working principle is as follows: the fan is driven to start and continuously drive the air to circulate along the air inlet component 21, the file cavity 12, the air outlet component 22 and the temperature sensing tube 311, thereby realizing the air exchange between the temperature sensing tube 311 and the file cavity 12. The refrigeration component 32 circulates the coolant into the temperature control component 31, and the coolant realizes heat exchange with the air through the temperature sensing tube 311, thereby reducing the air temperature in the temperature sensing tube 311. The circulating air can reduce the ambient temperature of the files in the intelligent filing cabinet, which helps to extend the service life of the file box and the files.

[0088] This embodiment also provides a management method, including verifying identity through a biometric module when entering the warehouse, the system generating an encrypted QR code and printing a label;

[0089] Automatically allocate storage space based on RF positioning results, light up the LED indicator and open the cabinet door;

[0090] Update inventory data after confirming the placement status of files through weight, infrared and photoelectric sensors;

[0091] During inventory, RFID reading, visual inspection and sensor cross-verification are used to generate inventory reports and upload them to the cloud.

[0092] As an optional embodiment, a two-person verification mechanism is activated according to the file classification when leaving the warehouse, triggering camera recording; information is compared through multi-spectral scanning, and an alarm is triggered and the cabinet door is locked in case of abnormality; the operation log is sent to the supervision terminal via the wireless module.

[0093] In this embodiment, a management method includes a file storage operation process, a file storage operation process and a file inventory process.

[0094] The operation process of file storage: identity verification is carried out through the biometric module integrated into the cabinet. The biometric module includes but is not limited to a multi-verification combination consisting of a fingerprint recognition unit, a face recognition camera, an IC card reader and a numeric keypad;

[0095] After verification, the central processing unit retrieves the user rights configuration file and activates the human-computer interaction interface of the archive management system;

[0096] The file metadata information is input through the scanning device, and the system generates an encrypted QR code containing the file number, storage time, and storage period, and drives the label printer to output a thermal QR code label;

[0097] Based on the radio frequency positioning system to detect the occupancy status of each file cavity, the control module automatically allocates the optimal storage location and activates the LED indicator of the corresponding file cavity, and simultaneously controls the drive motor to open the designated cabinet door;

[0098] After the weight sensor confirms that the file box has been taken out, the infrared detection device monitors the file placement operation, and the pressure sensor detects the load-bearing changes of the storage space in real time;

[0099] When the photoelectric sensor detects that the file box is fully returned to its original position, the central processing unit updates the inventory database and turns off the storage position indicator light;

[0100] After the cabinet door magnetic lock detects that the door is closed, it recalculates the environmental parameters through the temperature compensation algorithm and starts the thermostat and dehumidifier to adjust the environment.

[0101] Identity identification ensures that the operation is performed by an authorized administrator, who enters the system and enters the file information. The file information QR code label is printed and affixed to the file cover to complete the information entry, which helps to optimize the file management process and improve the file management level.

[0102] Archive outbound operation process: The system initiates differentiated management modes based on the type of outbound request. When confidential archives are involved, a two-person verification mechanism is activated and the built-in camera recording device in the cabinet is started.

[0103] A multi-spectral scanning head is used to deeply analyze the QR code, and the operation timestamp is recorded through the blockchain evidence storage module. If a mismatch between the file number and the requested information is detected, an audible and visual alarm is triggered and the cabinet door opening and closing function is frozen;
