Description

Technical Field

[0001] This application relates to the technical field of data processing, and particularly relates to a method, device, and electronic device for reading files in an RFID intelligent file cabinet. Background Art

[0002] As an efficient file management system, the RFID intelligent file cabinet relies on the non-contact communication between RFID tags and antennas to achieve fast file inventory, real-time tracking, and information management. However, in practical applications, the RFID intelligent file cabinet often faces complex file reading environments, such as file occlusion.

[0003] File occlusion is a typical problem. When a file is partially occluded by other folders, metal clamps, or cabinet materials, the radio frequency signal will be weakened due to multipath attenuation or shielding effects, resulting in the inability to effectively activate the tags on the file. The tag stacking caused by file occlusion further exacerbates the signal conflict problem. When multiple files are stacked closely, the signals reflected by the tags interfere with each other, forming a complex reading environment that makes it difficult for the system to distinguish the unique identifiers of each tag, thus being unfavorable for reading files.

[0004] Therefore, there is an urgent need for a method, device, and electronic device for reading files in an RFID intelligent file cabinet. Summary of the Invention

[0005] This application provides a method, device, and electronic device for reading files in an RFID intelligent file cabinet, which is convenient for reading the files stored in the RFID intelligent file cabinet.

[0006] In a first aspect of the present application, a method for reading files of an RFID intelligent filing cabinet is provided. The method includes: obtaining the correspondence between a radio frequency induction device and an RFID tag, where the radio frequency induction device is disposed on the RFID intelligent filing cabinet, and the RFID tag is disposed on a file stored in the RFID intelligent filing cabinet; controlling a first radio frequency induction device to send a first radio frequency signal to a first file and controlling a second radio frequency induction device to send a second radio frequency signal to a second file according to the correspondence to obtain a target coupling field, where the radio frequency induction device includes the first radio frequency induction device and the second radio frequency induction device, the file includes the first file and the second file, a first radio frequency distance between the first radio frequency induction device and the first file and a second radio frequency distance between the second radio frequency induction device and the second file both meet preset conditions, and signal frequencies and signal amplitudes corresponding to the first radio frequency signal and the second radio frequency signal are different; obtaining a first resonance signal sent by a first RFID tag corresponding to the first file and obtaining a second resonance signal sent by a second RFID tag corresponding to the second file according to the target coupling field; and reading the first file and the second file based on signal characteristics corresponding to the first resonance signal and the second resonance signal.

[0007] By adopting the above technical solutions, by establishing a one-to-one correspondence between the radio frequency induction devices and the documents, each device can emit radio frequency signals for specific documents, reducing the probability of interference problems that may be caused by multiple induction devices simultaneously emitting signals to all documents, and achieving precise control. Each radio frequency signal has a unique frequency and amplitude, ensuring that the signals of different documents do not have spectral conflicts in the target coupling field, thus greatly improving the signal separation ability. The system dynamically adjusts the signal power and coverage range according to the distance between the document and the induction device to ensure that the signal intensity is suitable for the reading requirements of the document. Multiple radio frequency devices work together to generate a complex target coupling field through cross signals to adapt to the complex environment inside the file cabinet. Even when the documents are stacked or partially blocked, the blocked RFID tags can be excited through the multipath effect. Each RFID tag has a specific resonant frequency, which is an inherent property of the tag. Even if the signal is blocked, it may still generate a response within a specific frequency range. The system extracts signals based on the resonant characteristics of the tags, can effectively distinguish weak signals from noise, and thus improves the robustness of reading. The radio frequency induction devices are distributed at different positions in the file cabinet. Through reasonable layout, the reading range of the entire cabinet is covered. Any document in the cabinet, whether located in the corner or in the center, can be covered by the signals emitted by different devices, thus reducing the reading blind area. The coupling field can indirectly excite the blocked tags through the multipath effect and reflected signals. By simultaneously reading different documents with multiple radio frequency devices, parallel reading of multiple documents is achieved, improving the overall reading efficiency. Therefore, it is convenient to read the documents stored in the RFID intelligent file cabinet.

[0008] Optionally, obtaining the correspondence between the radio frequency induction device and the RFID tag specifically includes: constructing a spatial coordinate system according to the RFID intelligent file cabinet; obtaining the installation position of the radio frequency induction device and the storage position of the file corresponding to the RFID tag; marking the installation position and the storage position in the spatial coordinate system to obtain a file cabinet model; calculating the relative position relationship between the radio frequency induction device and the RFID tag through the file cabinet model; and constructing the correspondence according to the relative position relationship.

[0009] By adopting the above technical solution, the physical structure of the RFID intelligent file cabinet is mapped into a mathematical model, so that each position of the file cabinet can be accurately described by coordinates. This way enables the storage position of the file and the installation position of the radio frequency induction device to be unified under the same coordinate system, laying a foundation for subsequent reading and control. Marking the radio frequency induction device and the file storage position in the space model can clarify the coverage range of each induction device and its relative relationship with the file, reducing the reading blind area. By updating the file storage position in the space coordinate system in real time, it can adapt to the scenarios of random placement or dynamic adjustment of files. Even if the positions of some files in the file cabinet change, only the coordinate data of the file positions need to be updated, without re-arranging the hardware devices. By calculating the relative position relationship between the induction device and the file, the signal power and beam direction can be adjusted according to the distance and angle, improving the signal weakening problem caused by file stacking or occlusion. The file cabinet model in the space coordinate system can be used for visualizing the position relationship between the radio frequency induction device and the file, facilitating the maintenance personnel to view the internal layout and reading status of the file cabinet.

[0010] Optionally, controlling the first radio frequency induction device to send a first radio frequency signal to the first file and controlling the second radio frequency induction device to send a second radio frequency signal to the second file according to the corresponding relationship to obtain a target coupling field specifically includes: responding to an operation request for the first file and the second file stored in the RFID intelligent file cabinet; based on the operation request, determining the first radio frequency induction device corresponding to the first file and the second radio frequency induction device corresponding to the second file through the corresponding relationship; based on the operation request, sending a first radio frequency instruction containing the first radio frequency signal to the first radio frequency device and sending a second radio frequency instruction containing the second radio frequency signal to the second radio frequency induction device, where the first radio frequency instruction is used to control the first radio frequency induction device to send the first radio frequency signal to the first file, and the second radio frequency instruction is used to control the second radio frequency induction device to send the second radio frequency signal to the second file; generating the target coupling field after a preset time period or after a preset number of operation requests.

[0011] By adopting the above technical solution, the system sends RF commands to specific devices, clarifies the command content, and achieves high-precision control of the devices. The commands received by different devices can be executed simultaneously, thus supporting parallel operations of multiple files and improving the reading efficiency of the overall system. During the reading process, the system generates a target coupling field through the interaction of different RF signals. This field not only activates the RFID tags of the target files but also utilizes reflection and multipath effects to cover file tags that may be blocked. Especially in the case of file stacking or when some tag signals are blocked, the coupling field can compensate for signal losses and improve the comprehensiveness of reading. The system generates the coupling field after a preset time period or when a certain number of operation requests are reached, ensuring that the reading operation is completed within a reasonable range and avoiding energy waste that may be caused by long-term generation of the coupling field. Through the generated coupling field, multi-signal interaction can cover files in complex scenarios and improve the reading ability in cases of file occlusion or signal weakening.

[0012] Optionally, the reading of the first file and the second file based on the signal characteristics corresponding to the first resonance signal and the second resonance signal specifically includes: obtaining the frequency, amplitude, and phase corresponding to the first signal characteristic of the first resonance signal; obtaining the frequency, amplitude, and phase corresponding to the second signal characteristic of the second resonance signal; determining a first resonance point and a second resonance point based on the first signal characteristic and the second signal characteristic; and mapping both the first resonance point and the second resonance point to the file cabinet model to read the first file and the second file.

[0013] By adopting the above technical solution, frequency, amplitude, and phase are the basic characteristics of signals. By accurately obtaining these characteristics of each resonance signal, the system can ensure a high degree of accuracy in the reading process. By comparing the resonance signal characteristics of different files, multiple file tags can be accurately identified and distinguished, avoiding signal cross-interference and improving the reading success rate. The resonance point is the point where the signal reaches the best response. By measuring and determining the resonance point corresponding to each file, the reading efficiency and accuracy can be maximized. Since the working principle of RFID tags is based on the resonance principle, this method can ensure that the RF signal is fully activated and the response of the file tag is obtained. Even if the file is partially blocked, the ability to accurately identify the resonance point enables the system to read the blocked or stacked files more effectively. The system can adjust the signal according to the resonance response of different files, thereby compensating for signal losses caused by occlusion. Through coordination using the mapping model, the efficiency of parallel reading is optimized. Even if the storage positions and signal characteristics of the files are different, the system can effectively identify multiple files through the relative position relationship and signal characteristics.

[0014] Optionally, the method further includes: controlling a third radio frequency sensing device to send a third radio frequency signal to a third file, where the third radio frequency sensing device is any one of the plurality of radio frequency sensing devices, the third file is any one of the plurality of files, and the third RFID tag corresponding to the third radio frequency sensing device and the third file satisfies the corresponding relationship; after a preset sensing duration, if it is confirmed that the third resonance signal sent by the third RFID tag is not received, a random pulse signal is generated; the random pulse signal is sent to the third RFID tag to activate the third RFID tag.

[0015] By adopting the above technical solution, under normal circumstances, after the third radio frequency sensing device sends a radio frequency signal to the third file, the resonance signal sent by the third RFID tag should be received. However, due to various reasons, the RFID tag may not respond in time. By generating and sending a random pulse signal, the system can effectively activate the tag and make it respond. This way enables the system to intelligently perform failure recovery, avoid waiting for too long, and thus improve the operation fluency of the entire filing cabinet. Since the communication between the radio frequency sensing device and the RFID tag may be affected by factors such as distance, angle, and environmental factors, a single device or tag failure may lead to a reading failure. By designing the random pulse signal as a supplement, the system can avoid interrupting the file reading process due to accidental failures between devices. If a certain radio frequency sensing device fails to correctly activate the tag after sending a signal, reactivation through the random pulse signal can ensure the normal reading of other devices or tags, thereby enhancing the robustness of the entire system.

[0016] Optionally, the method further includes: obtaining a fourth resonance signal sent by the third RFID tag after being activated by the random pulse signal, where the fourth resonance signal includes the file data corresponding to the third file, and one resonance signal corresponds to one file data; inputting both the fourth resonance signal and the file data corresponding to the third file into a convolutional neural network to obtain a prediction result, where the prediction result is used to verify the authenticity between the file data corresponding to the third file included in the fourth resonance signal and the actual data.

[0017] By adopting the above technical solution, when the fourth resonance signal sent by the third RFID tag contains the file data of its corresponding file, the convolutional neural network can process and analyze these signals, and judge whether the data is consistent with the actual stored data based on its features. In this way, even if the RFID tag is tampered with or misread, the system can identify and filter out untrue signals through the deep learning characteristics of the convolutional neural network. The convolutional neural network has a powerful pattern recognition ability, which can automatically extract important features from the input signals and perform classification or regression prediction. In this application, by comparing the fourth resonance signal with the actual file data through the convolutional neural network, potential data inconsistencies or errors can be automatically detected. By using the convolutional neural network, more refined judgments can be made based on complex signal features. In practical applications, RFID tags may be affected by external interference, resulting in signal distortion or partial data loss. By comparing the prediction results of the convolutional neural network on the signals with the actual data, the system can still tolerate errors through the learned features when the data is interfered, automatically correct errors, and improve the robustness of the system. The convolutional neural network can identify irregular patterns. Even if the signal is affected by noise or damage, it can maintain a high-accuracy prediction of the file data through the trained features.

[0018] Optionally, the method further includes: obtaining the reading results of multiple files stored in the RFID intelligent file cabinet; sending the reading results and the file cabinet model to the AR glasses worn by the user, so as to display the reading results and the file cabinet model to the user through the AR glasses.

[0019] By adopting the above technical solution, through the AR glasses, the user can see the file reading results and the file cabinet model of the RFID intelligent file cabinet in real time. This enables the user not to rely on traditional simple text or other two-dimensional information display methods, and can obtain information in a more intuitive and vivid way. The user can interact with virtual data in the physical space, making file management more intuitive and efficient. The AR glasses can superimpose virtual content onto the real environment, allowing the user to see the real-time status of the file cabinet, the reading situation of each file, and the specific location where the file is stored. This visual enhancement significantly improves the interactivity and user experience of file management.

[0020] In a second aspect of the present application, a file reading device for an RFID intelligent file cabinet is provided. The file reading device includes an acquisition module and a processing module. Among them, the acquisition module is used to acquire the correspondence between a radio frequency induction device and an RFID tag. The radio frequency induction device is arranged on the RFID intelligent file cabinet, and the RFID tag is arranged on the file stored in the RFID intelligent file cabinet. The processing module is used to control a first radio frequency induction device to send a first radio frequency signal to a first file and control a second radio frequency induction device to send a second radio frequency signal to a second file according to the correspondence, so as to obtain a target coupling field. The radio frequency induction device includes the first radio frequency induction device and the second radio frequency induction device. The file includes the first file and the second file. The first radio frequency distance between the first radio frequency induction device and the first file and the second radio frequency distance between the second radio frequency induction device and the second file both meet preset conditions. The signal frequencies and signal amplitudes corresponding to the first radio frequency signal and the second radio frequency signal are different. The processing module is further used to acquire a first resonance signal sent by a first RFID tag corresponding to the first file and a second resonance signal sent by a second RFID tag corresponding to the second file according to the target coupling field. The processing module is further used to read the first file and the second file based on the signal characteristics corresponding to the first resonance signal and the second resonance signal.

[0021] In a third aspect of the present application, an electronic device is provided. The electronic device includes a processor, a memory, a user interface, and a network interface. The memory is used to store instructions. The user interface and the network interface are both used to communicate with other devices. The processor is used to execute the instructions stored in the memory so that the electronic device executes the method described above.

[0022] In a fourth aspect of the present application, a computer-readable storage medium is provided. The computer-readable storage medium stores instructions, and when the instructions are executed, the method described above is executed.

[0023] In summary, one or more technical solutions provided in the present application have at least the following technical effects or advantages: By establishing a one-to-one correspondence between the radio frequency induction devices and the documents, each device can emit radio frequency signals for specific documents, reducing the probability of interference problems that may be caused by multiple induction devices simultaneously emitting signals to all documents and achieving precise control. Each radio frequency signal has a unique frequency and amplitude, ensuring that the signals of different documents do not cause spectrum conflicts in the target coupling field, thus greatly improving the signal separation ability. The system dynamically adjusts the signal power and coverage range according to the distance between the document and the induction device to ensure that the signal intensity is suitable for the reading requirements of the document. Multiple radio frequency devices work together to generate a complex target coupling field through cross signals to adapt to the complex environment inside the filing cabinet. Even when the documents are stacked or partially blocked, the blocked RFID tags can be excited through the multipath effect. Each RFID tag has a specific resonant frequency, which is an inherent property of the tag. Even if the signal is blocked, it may still generate a response within a specific frequency range. The system extracts signals based on the resonant characteristics of the tags, can effectively distinguish weak signals from noise, and thus improves the robustness of reading. The radio frequency induction devices are distributed at different positions in the filing cabinet. Through reasonable layout, the reading range of the entire cabinet body is covered. Any document in the cabinet, whether in the corner or in the center, can be covered by the signals emitted by different devices, thus reducing the reading blind area. The coupling field can indirectly excite the blocked tags through the multipath effect and reflected signals. By simultaneously reading different documents with multiple radio frequency devices, parallel reading of multiple documents is achieved, improving the overall reading efficiency. Therefore, it is convenient to read the documents stored in the RFID intelligent filing cabinet. Description of the Drawings

[0032] An RFID intelligent file cabinet is an efficient file management system. Through the non-contact communication between RFID tags and antennas, it can achieve rapid inventory, real-time tracking, and information management. However, in practical applications, RFID intelligent file cabinets often face complex reading environments, especially the problem of file occlusion.

[0033] File occlusion is a typical challenge. When a file is occluded by other files, metal fixtures, or parts of the cabinet structure, the radio frequency signal may be affected by multipath attenuation or shielding effects, resulting in the inability to effectively activate the tags on the file. At the same time, the problem of file stacking further exacerbates signal conflicts. When multiple files are stacked closely, the signals reflected by the tags will interfere with each other, causing the reading system to be unable to distinguish the unique identifiers of each tag, which is not conducive to reading the files.

[0034] To solve the above technical problems, this application provides a file reading method for an RFID intelligent file cabinet. Referring to Figure 1 , Figure 1 is a schematic flowchart of a file reading method for an RFID intelligent file cabinet provided in the embodiments of this application. This method is applied to a server and specifically includes steps S110 to S140. The above steps are as follows: S110. Obtain the correspondence between the radio frequency induction device and the RFID tag. The radio frequency induction device is set on the RFID intelligent file cabinet, and the RFID tag is set on the file stored in the RFID intelligent file cabinet.

[0035] Specifically, in the RFID intelligent file cabinet, the server is used to control the interaction between the RFID intelligent file cabinet and the radio frequency induction device, which can be a computer system or a server cluster. The radio frequency induction device, that is, the RFID reader or antenna, is used to transmit radio frequency signals and receive response signals from the RFID tag. The RFID tag is attached to the file stored in the file cabinet. The server is responsible for tracking the spatial position and mapping relationship between the radio frequency induction device and the RFID tag. In other words, the server needs to know which radio frequency induction device corresponds to the RFID tag in which file in order to accurately identify and read these files. The radio frequency induction devices are installed at appropriate positions on the RFID intelligent file cabinet, in specific areas of the cabinet body or around the door frame. These devices communicate with the tags via wireless signals. For example, each drawer, storage area, or specific folder of the file cabinet may be equipped with a radio frequency induction device for scanning the RFID tags of the files in the corresponding area. An RFID tag is attached to each file, and the unique identification information of the file, such as the file number, file type, etc., is embedded in the tag. When the radio frequency induction device sends a signal, these tags receive the signal and respond by reflection, transmitting the relevant information of the file. For example, in a file cabinet, documents may be identified with RFID tags, and the relevant information of the file is stored on each tag. The radio frequency induction device can receive the information of the tag during the scanning process. The server needs to obtain the exact positional relationship between the radio frequency induction device and the RFID tag in each file through means such as spatial coordinate positioning. This step is to ensure that the file can be correctly identified and tracked when being read. For example, the server will record the correspondence between radio frequency induction device 1 and file A, and radio frequency induction device 2 and file B. In this way, when a file needs to be read, the server knows which device to activate to read the tag of which file.

[0036] In a possible implementation manner, obtaining the correspondence between the radio frequency induction device and the RFID tag specifically includes: constructing a spatial coordinate system according to the RFID intelligent file cabinet; obtaining the installation position of the radio frequency induction device and the storage position of the file corresponding to the RFID tag; marking the installation position and the storage position in the spatial coordinate system to obtain a file cabinet model; calculating the relative positional relationship between the radio frequency induction device and the RFID tag through the file cabinet model; and constructing the correspondence according to the relative positional relationship.

[0037] Specifically, the spatial coordinate system refers to establishing a coordinate system within the space of the RFID intelligent filing cabinet, that is, based on the physical structure of the filing cabinet. This means that each area inside the filing cabinet can be represented by coordinates, such as using three axes X, Y, and Z to mark the positions in space. In this way, the specific positions of all radio frequency sensing devices and RFID tags can be accurately represented in this coordinate system. For example, if each drawer of the RFID intelligent filing cabinet has a different radio frequency sensing device, and each folder is placed at a different location, the spatial coordinate system can help determine the positions of each drawer and folder. For example, drawer 1 may be located at (X = 10, Y = 20, Z = 0), while drawer 2 is located at (X = 20, Y = 20, Z = 0). The server needs to obtain the positions of each radio frequency sensing device, that is, the installation positions, and the positions of each RFID tag, that is, the storage positions of the files. The positional relationship between these two will directly affect the transmission and reading effect of radio frequency signals. Suppose in drawer 1 of the filing cabinet, radio frequency sensing device 1 is installed, and file A is placed in this drawer, corresponding to the RFID tag. At this time, the installation position of radio frequency sensing device 1 is marked as (X = 20, Y = 20, Z = 0) in the spatial coordinate system, while the storage position of file A is (X = 20, Y = 20, Z = 1).

[0038] Marking the positions of radio frequency sensing devices and RFID tags in the spatial coordinate system constitutes a filing cabinet model. The filing cabinet model is a virtual spatial representation that helps the server or user understand the spatial relationship between radio frequency sensing devices and RFID tags. After establishing the filing cabinet model, the next step is to calculate the relative positional relationship between radio frequency sensing devices and RFID tags. The relative positional relationship can help the server understand which devices are responsible for reading which tags, and then optimize the signal transmission path. If the relative distance between radio frequency sensing device 1 and the tag of file A is 1 meter, the server can know that device 1 is responsible for reading the tag of file A. Calculating parameters such as these distances and angles can ensure the accurate transmission and reading of signals. The corresponding relationship refers to the mapping relationship between devices and files calculated through the spatial coordinate system and the filing cabinet model. The server uses these relationships to determine which radio frequency sensing device should communicate with the RFID tag of which file. Constructing this corresponding relationship can ensure that the RFID intelligent filing cabinet can accurately identify and read the tags of each file. Suppose there are multiple files in the filing cabinet, and each file has an RFID tag. By establishing a spatial coordinate system and calculating the relative positional relationship between devices and tags, the server will know that radio frequency sensing device 1 should read the tag of file A, radio frequency sensing device 2 should read the tag of file B, and so on. Each radio frequency sensing device is only responsible for scanning the tags of files within a specific area.

[0039] S120. According to the corresponding relationship, control the first radio frequency induction device to send a first radio frequency signal to the first document, and control the second radio frequency induction device to send a second radio frequency signal to the second document, to obtain a target coupling field. The radio frequency induction devices include a first radio frequency induction device and a second radio frequency induction device, the documents include a first document and a second document, the first radio frequency distance between the first radio frequency induction device and the first document, and the second radio frequency distance between the second radio frequency induction device and the second document both meet preset conditions, and the signal frequencies and signal amplitudes corresponding to the first radio frequency signal and the second radio frequency signal are different.

[0040] Specifically, by calculating the relative position relationship between each radio frequency induction device and the RFID tag in the document, the server knows which radio frequency induction device should communicate with the tag of which document. The server controls the radio frequency induction devices to send different radio frequency signals to different documents according to the position of each document. The first radio frequency induction device sends a signal to Document A, and the second radio frequency induction device sends a signal to Document B. In this way, the server can process the reading requests of multiple documents simultaneously. The target coupling field refers to the area where the radio frequency signal interacts with the document and the tag in space. When the radio frequency induction device sends a signal, the signal propagates between the document and the tag and forms a coupling field. This coupling field is the interaction area between the signal and the tag, which determines whether the RFID tag can receive the radio frequency signal and respond. Among them, the propagation distance of the radio frequency signal must also meet certain preset conditions to ensure that the signal can be effectively transmitted to the document and activate the tag. For example, the preset conditions may require that the distance between the radio frequency induction device and the document cannot be too far, otherwise the signal strength may not be sufficient to read the tag. The preset conditions may also include the signal attenuation amount, the signal strength, etc. To avoid signal interference, the first radio frequency signal and the second radio frequency signal have different frequencies and amplitudes. By using radio frequency signals with different frequencies and amplitudes, the mutual interference between multiple radio frequency signals can be avoided, that is, the signal crossover between different devices can be avoided. This can ensure that each radio frequency induction device can communicate with the target document independently and accurately.

[0041] For example, radio frequency signals are emitted from Radio Frequency Induction Device 1 and Radio Frequency Induction Device 2 respectively, and the signals propagate in the areas of Document A and Document B and interact with their respective RFID tags to form a coupling field. This coupling field is the interaction area between the radio frequency signal and the tag, where the RFID tag will respond and send back corresponding data. To ensure the reading effect, the server sets distance conditions. For example, the distance between Radio Frequency Induction Device 1 and Document A is 50 cm, and the distance between Radio Frequency Induction Device 2 and Document B is 40 cm. The server confirms that these distances meet the requirements of the signal strength to ensure that the signal can be effectively transmitted and the document information can be read.

[0042] In a possible implementation, according to the corresponding relationship, control the first radio frequency induction device to send a first radio frequency signal to the first file, and control the second radio frequency induction device to send a second radio frequency signal to the second file to obtain a target coupling field, which specifically includes: responding to an operation request for the first file and the second file stored in the RFID intelligent file cabinet; based on the operation request, through the corresponding relationship, determine the first radio frequency induction device corresponding to the first file and the second radio frequency induction device corresponding to the second file; based on the operation request, send a first radio frequency instruction containing the first radio frequency signal to the first radio frequency device, and send a second radio frequency instruction containing the second radio frequency signal to the second radio frequency induction device, where the first radio frequency instruction is used to control the first radio frequency induction device to send the first radio frequency signal to the first file, and the second radio frequency instruction is used to control the second radio frequency induction device to send the second radio frequency signal to the second file; after a preset time period or after a preset number of operation requests, generate a target coupling field.

[0043] Specifically, when the server receives an operation request for file reading, it starts to execute the next operation. The operation request can be that the user hopes to read the information of a certain file, or the server's reading requirements for multiple files. Suppose the user hopes to read file A and file B stored in the RFID file cabinet. After the server receives this request, it will start to process. According to the previously established corresponding relationship between the radio frequency induction device and the RFID tag, the server determines which radio frequency induction device needs to communicate with which file. For example, file A is read by radio frequency induction device 1, and file B is read by radio frequency induction device 2. For example, the RFID tags of file A and file B correspond to radio frequency induction device 1 and radio frequency induction device 2 respectively. The server determines to use radio frequency induction device 1 when reading file A and radio frequency induction device 2 when reading file B according to this corresponding relationship. According to the operation request, the server sends corresponding instructions to the radio frequency induction device. After receiving the first radio frequency instruction, the first radio frequency induction device sends a first radio frequency signal to file A; the second radio frequency induction device sends a second radio frequency signal to file B. For example, the server controls radio frequency induction device 1 to send a signal to file A and controls radio frequency induction device 2 to send a signal to file B. In this way, the two files will simultaneously receive different radio frequency signals, thereby activating their RFID tags.

[0044] Among them, the radio frequency instruction tells the radio frequency induction device when to send a signal to the document and the nature of the signal. For example, the first radio frequency instruction causes the radio frequency induction device 1 to send a radio frequency signal of a specific frequency to Document A, and the second radio frequency instruction causes the radio frequency induction device 2 to send a radio frequency signal of a different frequency to Document B. The differences in these signals help distinguish different documents and their tags. After the server sends out a radio frequency signal, the signal propagates between the document and the tag. After a certain time or a certain number of signal transmissions, the server generates a target coupling field. This coupling field refers to the interaction area between the radio frequency signal and the tag, and the signal will activate the tag within this area. For example, after the radio frequency signal is sent for a certain time, a stable coupling field will be formed between the radio frequency induction device and the tags of Document A and Document B. In this coupling field, the tag will respond to the radio frequency signal and send data back to the radio frequency induction device.

[0045] S130. According to the target coupling field, obtain the first resonance signal sent by the first RFID tag corresponding to the first document, and obtain the second resonance signal sent by the second RFID tag corresponding to the second document.

[0046] Specifically, the server will receive the signal sent by the RFID tag corresponding to the first document, and this signal is a resonance signal. When the RFID tag is excited by an external radio frequency signal, a resonance effect will be generated inside it, and the signal will be emitted back in a specific frequency and amplitude. In this case, the first resonance signal refers to the signal sent by the RFID tag of Document A, and this signal contains the relevant data or identification information of Document A. For example, after the RFID tag of Document A receives the radio frequency signal, it will reflect a resonance signal of a specific frequency, and this signal contains the unique identification information of Document A. By receiving this signal, the server knows the location or content of Document A. Similarly, the server will also obtain the signal sent by the RFID tag corresponding to the second document, such as Document B. This signal is also a kind of resonance signal, containing the relevant data or identification information of Document B. For example, the RFID tag of Document B will also reflect a resonance signal, and this signal contains the unique identification of Document B. By receiving this signal, the server knows the specific information of Document B.

[0047] S140. Based on the signal characteristics corresponding to the first resonance signal and the second resonance signal, read the first document and the second document.

[0048] Specifically, the resonant signal characteristics refer to the reflected signals emitted from the RFID tags. There are multiple characteristics that can describe it, such as frequency, amplitude, phase, etc. These characteristics are determined by factors such as the physical structure of the tag, the electromagnetic environment it is in, and its coupling relationship with the radio frequency signal. The server obtains two different signals reflected from the RFID tags in File A and File B: the first signal is the first resonant signal, and the second signal is the second resonant signal. Each signal has its own unique characteristics, such as frequency, amplitude, etc., and these characteristics will be used to distinguish File A and File B. The server identifies the specific information of File A and File B based on the characteristics of the received first and second resonant signals, such as frequency, amplitude, phase, etc. This means that the server can read the corresponding file data according to the unique identifier of each signal. The process of file reading not only involves obtaining the identifier of the tag, but may also include other metadata of the file, such as file status, storage location, etc.

[0049] In a possible implementation manner, based on the signal characteristics corresponding to the first resonant signal and the second resonant signal respectively, the first file and the second file are read. Specifically, it includes: obtaining the frequency, amplitude, and phase corresponding to the first signal characteristic of the first resonant signal; obtaining the frequency, amplitude, and phase corresponding to the second signal characteristic of the second resonant signal; determining the first resonant point and the second resonant point based on the first signal characteristic and the second signal characteristic; mapping both the first resonant point and the second resonant point to the file cabinet model to read the first file and the second file.

[0050] Specifically, the first resonant signal is the signal emitted from the RFID tag. After being excited by the radio frequency induction device, this signal will form a resonance effect between the tag and the radio frequency device. The resonant signal has unique characteristics, including frequency, amplitude, and phase. Frequency refers to the frequency at which the signal oscillates, measured in Hertz. In the RFID server, the frequency is a key feature used to identify and distinguish tags. Amplitude refers to the intensity of the signal, measured in decibels. The signal amplitude affects the transmission distance and reflection effect of the signal. Phase refers to the phase shift of the signal, reflecting the shift in position within the signal cycle. Similarly, the second resonant signal is the signal from another RFID tag, and its characteristics include frequency, amplitude, and phase. These characteristics may be different from those of the first tag because the physical properties of each tag, the environment, and the interaction with the radio frequency signal all affect the characteristics of the resonant signal. The resonance point refers to a specific characteristic point of the signal, based on parameters such as frequency, amplitude, or phase. By analyzing the frequency, amplitude, and phase of the signal, the server can determine the resonance point of each signal, which is the key characteristic point of the signal. The first resonance point and the second resonance point respectively represent the unique characteristic points of the reflected signals of the RFID tags corresponding to the two files. These resonance points help identify and distinguish the tags of each file. Mapping the first resonance point and the second resonance point to the filing cabinet model means that the server can associate the signal characteristics of each file with the actual position and storage status of the file. By mapping these signal characteristics to the filing cabinet model, the server can accurately identify the status and position of each file, thereby realizing the file reading operation. This reading method is not only based on tag identification but also associates the signal characteristics with the spatial structure of the filing cabinet, making the reading process more accurate and efficient.

[0051] In a possible implementation, the control unit controls the third radio frequency induction device to send a third radio frequency signal to the third file. The third radio frequency induction device is any one of the multiple radio frequency induction devices, and the third file is any one of the multiple files. The third radio frequency induction device and the third RFID tag corresponding to the third file satisfy the corresponding relationship. After a preset induction duration, if it is confirmed that the third resonant signal sent by the third RFID tag is not received, a random pulse signal is generated. The random pulse signal is sent to the third RFID tag to activate the third RFID tag.

[0052] Specifically, the third radio frequency induction device means that there are multiple radio frequency induction devices in the filing cabinet, and the server will select one of them to communicate with the target file. The third file represents a file in the filing cabinet, which is affixed with an RFID tag and communicates with the induction device through radio frequency signals like other files. Among them, the third file may be the first file or the second file, or other files. The third radio frequency signal is the signal sent by the radio frequency induction device to the third file, used to activate or communicate with the RFID tag on the file.

[0053] For example, assume there are three files in a filing cabinet: File A, File B, and File C, and File C is selected as the target file. The radio frequency induction device 3 sends a radio frequency signal to File C to attempt to activate the RFID tag on File C. The server has pre-established the correspondence between the radio frequency induction device and the files, that is, it knows which radio frequency induction device corresponds to which file. The server has clarified the matching relationship between the device and the tag through methods such as spatial coordinates and tag positions. For example, there is a predetermined relationship between the RFID tag on File C and the radio frequency induction device 3, and the server has confirmed that device 3 corresponds to File C, so as to ensure that the signal can be accurately sent to the RFID tag of File C.

[0054] The preset induction duration means that the server waits for a period of time to wait for a response signal from the RFID tag on File C. If no response signal from File C, that is, the resonance signal of the third RFID tag, is received within this time, the server considers that File C may be in a non-responsive state. If no valid signal is received, the server will automatically generate a random pulse signal. The purpose of this pulse signal is to activate the RFID tag because the tag may not respond correctly due to certain reasons, such as signal interference or other factors. For example, the RFID tag on File C fails to respond in time, perhaps because the signal is interfered with or the tag is in a dormant state. After the server waits for the set time and fails to receive a response signal, it generates a random pulse signal and sends it to the RFID tag on File C. The purpose of this random pulse signal is to wake up the RFID tag, activate it, and make it start responding to the signals of the radio frequency induction device. This process is usually used to solve the situation where the tag enters a dormant state or cannot respond normally in a harsh environment. Assume that the RFID tag of File C fails to respond to the radio frequency signal due to low battery power or other reasons. The server reactivates the tag by sending a random pulse signal, making it enter the working state so that it can receive and respond to subsequent radio frequency signals.

[0055] In a possible implementation manner, obtain the fourth resonance signal sent after the third RFID tag is activated by the random pulse signal. The fourth resonance signal includes the file data corresponding to the third file, where one resonance signal corresponds to one file data; input both the fourth resonance signal and the file data corresponding to the third file into a convolutional neural network to obtain a prediction result, and the prediction result is used to verify the authenticity between the file data corresponding to the third file included in the fourth resonance signal and the actual data.

[0056] Specifically, the third RFID tag refers to the RFID tag located on a certain file in the filing cabinet, and the server communicates with this tag through radio frequency signals. In the previous step, the server sent a random pulse signal to the third RFID tag to activate it. After activation, the RFID tag sends out a signal, and this resonance signal contains data related to this file. This signal will be received by a radio frequency induction device, representing the relevant information of the third file. Suppose the RFID tag of File C is activated, and it will send out a signal containing the data of File C. These data may include information such as the unique identifier of the file, the storage location, and the summary of the file content. The content carried by the resonance signal emitted by each RFID tag corresponds one-to-one to the specific file data. For example, the fourth resonance signal emitted by the tag of File C will only contain the data of File C and will not be confused with the data of other files. If File C contains the document "Contract A", then the RFID tag on File C will send out a signal, and the file data carried by this signal is the relevant information of "Contract A", such as the file number, creation date, etc.

[0057] The convolutional neural network is used to process and analyze signal data in the embodiments of the present application. The fourth resonance signal and the actual data of the file are input into the convolutional neural network for analysis. The convolutional neural network will analyze these input data and generate a prediction result. This result will be used to determine whether the fourth resonance signal is consistent with the actual file data, that is, to determine the authenticity of the file data. Suppose the fourth resonance signal contains the data of the RFID tag of File C. After the convolutional neural network inputs the data, it will analyze the features in the signal and compare them with the actual data of File C. The prediction result of the convolutional neural network may be "file data matches" or "file data does not match", that is, to judge the correctness of the file data. The output result of the convolutional neural network will be used to verify whether the file data in the fourth resonance signal is consistent with the actually stored file data. Through this method, the server can detect whether the file data has been tampered with, damaged, or has errors. The signal emitted by the RFID tag of File C is compared with the information of File C actually stored in the database. If the prediction result of the convolutional neural network shows that the file data does not match, the server can find that the data of this file may have been modified or there is an abnormality, thus triggering an alarm.

[0058] In a possible implementation manner, refer to Figure 2 , Figure 2 which is another process schematic diagram of a file reading method for an RFID intelligent filing cabinet provided by the embodiments of the present application. Specifically, it includes steps S210 to S220, and the above steps are as follows: S210, obtain the reading results of multiple files stored in the RFID intelligent filing cabinet; S220, send the reading results and the filing cabinet model to the AR glasses worn by the user, so as to display the reading results and the filing cabinet model to the user through the AR glasses.

[0059] Specifically, the server of the RFID intelligent filing cabinet has read the relevant information of multiple files through RFID technology. Each file has an RFID tag, and the server obtains the status, location, or other identification information of the file through a radio frequency induction device. Assume that there are multiple files stored in the filing cabinet, such as File A, File B, and File C. Through the radio frequency induction device, the server has successfully obtained the reading results of these files, such as the number of File A, the location of File B, the creation time of File C, etc. The reading results and the filing cabinet model refer to the file information in the RFID intelligent filing cabinet and the 3D model of the filing cabinet itself. These data are transmitted to the AR glasses worn by the user. As an intelligent device, the AR glasses can superimpose this information on the real world for display.

[0060] For example, the user wears AR glasses, and the server transmits the reading results of File A, such as the number, location, etc., and the 3D model of the entire filing cabinet to the AR glasses. The AR glasses will display this information, perhaps by means of augmented reality, superimposed on the filing cabinet seen by the user, to help the user understand the location and status of the file. What the user sees through the AR glasses is a view that combines virtual and real, showing the file information stored in the filing cabinet and the 3D structure of the filing cabinet. The AR glasses can update the status or location of the file in real time according to these data. For example, in actual operation, the user may want to find File A. When the user views the filing cabinet through the AR glasses, the AR glasses will display the specific location where File A is located according to the previously transmitted filing cabinet model and mark the relevant information of File A in the view, such as the file number, creation date, etc. The user can then directly locate and find File A based on this information.
