Description

Technical Field

[0001] This application relates to the field of intelligent book anti-theft, and in particular to a turnstile security gate and its book anti-theft method, as well as corresponding devices and media. Background Technology

[0002] In libraries and other book lending venues, anti-theft management of books is crucial for maintaining the safety of book resources and the normal circulation order. Traditional anti-theft methods mainly involve installing magnetic or electronic tags on books to achieve the anti-theft function. Specifically, when a book passes through the detection equipment, if the book has not gone through the normal borrowing process, the tag installed on the book will identify it and trigger an alarm.

[0003] However, when the detection equipment has multiple channels, traditional book theft prevention methods cannot accurately determine the specific gate channel where the unborrowed book is located. That is, when people pass through multiple channels at the same time, it is difficult to identify the specific person carrying the unborrowed book. This will result in the inability to quickly locate the specific channel when the unborrowed book is detected, and thus the inability to identify the person carrying the unborrowed book. This increases the time and effort for administrators to find and deal with the problem. Administrators need to check multiple channels, which not only reduces work efficiency but also increases management costs. Summary of the Invention

[0004] The purpose of this application is to provide a turnstile security gate, a book anti-theft method, and corresponding devices and media.

[0005] According to one aspect of this application, a method for preventing book theft is provided, comprising: Real-time monitoring of the sensing data of the human body detection device; when the sensing data indicates that there is human movement in the target space, the wireless sensing signal emitted by the book radio frequency identification tag received by the radio frequency identification device installed on each gate channel is obtained. The target gate channel where the corresponding book is located is determined based on the wireless sensing signal; The book attribute information obtained from the wireless sensing signal is verified. When the book attribute information indicates that the corresponding book has been borrowed, the corresponding gate release device is driven to open the target gate channel. When the book attribute information indicates that the corresponding book has not been borrowed, the alarm device corresponding to the target gate channel is controlled to issue an alarm prompt.

[0006] According to another aspect of this application, a book anti-theft device is provided, comprising: The sensing signal acquisition module is configured to monitor the sensing data of the human body detection device in real time. When the sensing data indicates that there is human movement in the target space, it acquires the wireless sensing signal emitted by the book radio frequency identification tag received by the radio frequency identification device set on each gate channel. The target gate channel determination module is configured to determine the target gate channel where the corresponding book is located based on the wireless sensing signal. The attribute information verification module is configured to verify the book attribute information obtained by parsing the wireless sensing signal. When the book attribute information indicates that the corresponding book has been borrowed, the module drives the corresponding gate release device to open the target gate channel. The alarm control module is configured to control the alarm device corresponding to the target gate channel to issue an alarm when the book attribute information indicates that the corresponding book has not been borrowed.

[0007] According to another aspect of this application, a turnstile security gate is provided, comprising multiple turnstile devices and a control center, wherein a gate passage is formed between adjacent turnstile devices, and the control center is used to execute the steps in the book anti-theft method to achieve anti-theft control of books.

[0008] According to another aspect of this application, a non-volatile readable storage medium is provided, which stores a computer program implemented according to the book anti-theft method in the form of computer-readable instructions, wherein the computer program, when invoked by a computer, executes the steps included in the method.

[0009] The technical solution of this application has many advantages, including but not limited to the following aspects: This application uses a human detection device to sense human movement within a target space, automatically acquiring the wireless sensing signal emitted by the book's RFID tag. Based on the signal characteristics of this wireless sensing signal, it determines the gate channel where the book is located. Then, it verifies the received book attribute information. When the book attribute information indicates that the book has been borrowed, it drives the corresponding gate release device to open the target gate channel, allowing the reader to pass smoothly. When the book attribute information indicates that the corresponding book has not been borrowed, it controls the alarm device corresponding to the gate channel where the book is located to issue an alarm reminder. At this time, it can accurately locate the specific gate channel of the unborrowed book, thereby identifying the reader carrying the unborrowed book.

[0010] Specifically, this application can directly lock the gate channel when it detects that a book has not been borrowed, avoiding the inefficiency of administrators having to check multiple channels when an alarm is issued, greatly saving management costs and time, and ensuring the safety and normal circulation of book resources.

Detailed Implementation

[0013] The book anti-theft method of this application can be programmed into a computer program product and deployed on a server for implementation. For example, in an exemplary application scenario of this application, the method is integrated into the control center of a turnstile security door to achieve management and control of book anti-theft. In a typical embodiment of this application, combined with... Figure 1The turnstile security gate includes multiple turnstile devices 100 and a control center 200. The multiple turnstile devices 100 are arranged side by side, forming a gate passage 300 between adjacent turnstile devices 100. Each turnstile device 100 includes a control board 110, a human body detection device 120, a radio frequency identification device 130, a gate release device 140, and a gate baffle 150. The gate baffle 150 includes a left gate baffle 151 and a right gate baffle 152. The left gate baffle 151 and the right gate baffle 152 are arranged opposite each other on the sides of adjacent turnstile devices 100, together forming the two side boundaries of the gate passage 300 for controlling the passage of personnel. Theoretically, only one gate baffle 150 can be used to control the passage of personnel, and those skilled in the art can implement it accordingly. The control center 200 is communicatively connected to the control board 110 corresponding to the plurality of turnstile devices 100. The control center 200 generates corresponding control commands based on preset logic rules or information sent by the control board 110, and sends the control commands to the control board 110 to drive the corresponding turnstile device 100 to complete the corresponding borrowing operation and gate control. The control board 110 is electrically connected to the human body detection device 120, the radio frequency identification device 130 and the gate release device 140. The output end of the gate release device 140 is connected to the gate baffle 150 to drive the gate baffle 150 to rotate and control the passage of personnel.

[0014] Specifically, when the human detection device 120 senses human movement within the target space, the control board 110 acquires the wireless sensing signals emitted by the book's RFID tag received by the RFID devices 130 installed on each gate channel 300. Based on these wireless sensing signals, the control board 110 determines the target gate channel 300 where the corresponding book is located. Next, the control board 110 verifies the book attribute information obtained from the analysis of the wireless sensing signals. When the book attribute information indicates that the corresponding book has been borrowed, the control board 110 drives the corresponding gate release device 140 to open the target gate channel 300; when the book attribute information indicates that the corresponding book has not been borrowed, the control board 110 controls the alarm device corresponding to the target gate channel 300 to issue an alarm.

[0015] In some embodiments, the gate device 100 further includes an identity recognition module, which includes a facial recognition device, a card recognition device, and / or a barcode recognition device. The identity recognition module can be selectively installed according to actual needs and is used to verify the identity of readers upon entry into the library, thereby opening the gate to allow readers to enter. Specifically, the facial recognition device can capture the reader's facial features through a camera and compare them with pre-stored facial information to achieve fast and accurate identity recognition; the card recognition device can read information from the reader's library card, ID card, or other valid documents to verify the reader's identity by confirming the validity of the document; the barcode recognition device can scan the barcode certificate provided by the reader, such as the electronic library card barcode on a mobile phone, thereby completing the identity verification process. The flexible configuration and combined use of the identity recognition module provides readers with multiple convenient ways to enter the library, while also enhancing the library's management efficiency and security regarding personnel access.

[0016] In another embodiment, see Figure 2 The radio frequency identification device 130 includes an antenna array 131 and a read / write module 132. The antenna array 131 and the read / write module 132 are electrically connected. Each antenna element in the antenna array 131 adopts an open-circuit coil design, and an electronic switch circuit is integrated at the open circuit for polling control of the working state of multiple antenna arrays 131. When the control board 110 verifies that the human identity information matches the preset legitimate user information, the main control module 200 issues a corresponding polling command based on a preset polling order. Based on the polling command issued by the main control module 200, the read / write module 132 controls the coil in the antenna array 131 of the current gate channel 300 to close through the electronic switch circuit, while keeping the electronic switch circuits of other gate channels open. At this time, the radio frequency excitation signal generated by the read / write module 132 is transmitted through the activated antenna array 131. After receiving the wireless sensing signal emitted by the book RFID tag, the read / write module 132 demodulates and decodes the signal, and uploads the decoded data to the control board 110, while suppressing signal interference caused by the operation of other antenna arrays 131. By polling multiple antenna arrays 131, the control board 110 obtains the wireless sensing signal emitted by the book RFID tag received by the antenna array 131 on each gate channel. Based on the wireless sensing signal, the control board 110 determines the target gate channel where the book is located.

[0017] The book anti-theft method of this application can be programmed into a computer program product and deployed on a server to run.

[0018] Please see Figure 3 A book anti-theft method according to this application, in a typical embodiment, includes the following steps: Step S5100: Real-time monitoring of the sensing data of the human body detection device; when the sensing data indicates that there is human movement in the target space, acquiring the wireless sensing signal emitted by the book radio frequency identification tag received by the radio frequency identification device installed on each gate channel. In libraries and other book lending facilities, anti-theft detection equipment is installed at the exits to prevent books or materials from being taken out without being checked out. However, when multiple people pass through the anti-theft detection equipment simultaneously, if the specific gate where the unchecked book is located cannot be accurately identified, it will be difficult to quickly locate the gate when the unchecked book is detected. Consequently, it will be impossible to identify the reader carrying the unchecked book, increasing the time and effort required for administrators to find and handle the problem.

[0019] To address the aforementioned issues, this application utilizes human body detection and radio frequency identification (RFID) technologies to locate unborrowed books, accurately determining their location within the gate passage and enhancing anti-theft efficiency. Specifically, this step involves a human body detection device that monitors the dynamic situation within the gate passage in real time. This device employs high-precision sensor technologies, such as infrared sensors, microwave radar sensors, or lidar sensors. These high-precision sensors can detect human movement non-contactly and possess high sensitivity and accuracy. For example, an infrared sensor detects infrared radiation emitted by a human body to determine if someone has entered the gate passage. When a person enters the detection range of the infrared sensor, the difference in body temperature compared to the surrounding environment causes a change in the intensity of infrared radiation received by the sensor, triggering a wireless sensing signal. A control board mounted on the gate controls the corresponding infrared sensor to collect these wireless sensing signals in real time and analyzes and processes the collected signals to determine if human movement has occurred.

[0020] When a human detection device senses human movement within the target space, it acquires the wireless sensing signals emitted by the book's RFID tag. In one embodiment, multiple RFID devices are installed on both sides or top of the gate channel. Each RFID device includes an antenna array and a reader / writer (hereinafter referred to as the read / write module). The RFID device utilizes a precise signal capture and processing mechanism to ensure efficient and accurate reception and parsing of the wireless sensing signals emitted by the book's RFID tag. Specifically, the antenna array transmits radio frequency signals at a preset frequency and power. When the RFID tag on the book enters the signal coverage area of ​​the antenna array, the RFID tag is activated and emits sensing signals. These sensing signals contain detailed attribute information of the book, such as its unique identifier (e.g., ISBN number), title, author, and publisher. After receiving these sensing signals, the read / write module demodulates and decodes them, extracts the valid information, and transmits it to the control board for further analysis and verification. It is easy to understand that each gate channel is equipped with a set of antenna arrays, and each set of antenna arrays is arranged in a specific layout to cover the entire channel area. When the antenna array receives the sensing signal emitted by the RFID tag of the book, the reader will analyze the received signal and extract the book attribute information.

[0021] In some embodiments, the sensing data from human detection devices installed on each gate channel is monitored in real time. When only one gate channel's human detection device detects human movement, that gate channel is directly identified as the target gate channel based on the sensing data. At this point, there is no need to further analyze the signal strength or other characteristics of the wireless sensing signals received by the RFID device to accurately locate the channel where the book is located. Subsequently, based on the determination of this target gate channel, the received book attribute information is further verified to determine the book's borrowing status and execute corresponding gate control or alarm operations.

[0022] Step S5200: Determine the target gate channel where the corresponding book is located based on the wireless sensing signal; Each gate is equipped with a Radio Frequency Identification (RFID) device. When a book passes through a gate, the wireless signal emitted by the book's RFID tag is captured by the RFID device located in each gate. The RFID device determines the distance between the book and the device by measuring the strength of the wireless signal, thus identifying the gate where the book is located. Specifically, each RFID device receives the signal emitted by the book's RFID tag and measures its strength. Signal strength is a parameter reflecting the degree of attenuation during signal propagation, measured in decibels (dB). The closer the book is to the RFID device, the stronger the signal; conversely, the farther the book is from the RFID device, the weaker the signal. Therefore, by comparing the signal strengths received by different RFID devices, the gate where the book is located can be determined.

[0023] In one embodiment, the location of the book is determined by analyzing the propagation direction and angle of the wireless sensing signal, specifically through phase difference measurement of a multi-antenna array. Each RFID device's antenna array can measure the phase of the received signal. By comparing the phase difference between signals received by different antenna arrays, the propagation direction and angle of the signal are calculated. Combined with the signal strength and propagation direction, the book's location is accurately determined.

[0024] Step S5300: Verify the book attribute information obtained based on the wireless sensing signal. When the book attribute information indicates that the corresponding book has been borrowed, drive the corresponding gate release device to open the target gate channel. When the RFID device receives the wireless sensing signal emitted by the RFID tag on a book, it demodulates and decodes the signal to extract the book's attribute information. This attribute information includes the book's unique identifier (such as ISBN), title, author, publisher, and other basic information, as well as crucial borrowing status information. The borrowing status information can be represented in various ways, such as through the status of the anti-theft tag (e.g., "borrowed" or "not borrowed"), or by matching the book's unique identifier with records in the library's borrowing database.

[0025] In some embodiments, the parsed book attribute information is first preliminarily verified to ensure the integrity and correctness of the data. For example, it checks whether the unique identifier of the book conforms to the preset encoding rules, or verifies whether the data checksum is correct. If data anomalies or missing data are found, the signal is re-acquired or an error message is issued. After the preliminary verification is completed, the borrowing status of the book is judged according to the preset verification rules. Specifically, the borrowing status is determined by checking the anti-theft flag bit in the book attribute information. The anti-theft flag bit is a specific data bit stored in the book's RFID tag, used to directly identify whether the book has been borrowed. When the status of the anti-theft flag bit is "borrowed", it is determined that the book has completed the legal borrowing procedure; conversely, if the status is "not borrowed", it is determined that the book has not been legally borrowed.

[0026] In another embodiment, the unique identifier of the book is used for interactive verification with the library's borrowing database. The parsed unique identifier of the book is sent to the library's backend database for querying to check if the book has a valid borrowing record. This embodiment can obtain more comprehensive borrowing information, such as borrower, borrowing time, and due date, thereby achieving more refined management. The database query process uses efficient indexing technology to ensure rapid response under large data volumes. At the same time, a strict concurrency control mechanism is implemented to prevent data inconsistencies when multiple users query simultaneously.

[0027] When the verification result shows that the book has been legally borrowed, a corresponding control command is generated to drive the gate release device of the target gate channel to perform the opening operation. In some embodiments, the gate release device consists of a motor, a transmission mechanism, and a gate baffle. The control command precisely specifies parameters such as the position of the target gate channel and the opening time to ensure that only the channel containing readers carrying borrowed books will be opened. Before sending the control command, a final confirmation check is performed, such as verifying whether the target gate channel is in an operable state or checking for other safety restrictions. After the opening operation is executed, the gate status is continuously monitored to ensure that the gate is fully open and remains open for an appropriate time for readers to pass through.

[0028] Step S5400: When the book attribute information indicates that the corresponding book has not been borrowed, control the alarm device corresponding to the target gate channel to issue an alarm prompt.

[0029] When the book attribute information is verified to indicate that the corresponding book has not been borrowed, the alarm device corresponding to the target gate channel will be immediately triggered to perform an alarm prompt operation. In one embodiment, the alarm device consists of multiple sub-modules, including a high-brightness LED warning light array, a high-decibel buzzer, and a digital voice broadcast unit. The LED warning lights will flash red light at a preset frequency, using a gradual frequency change from slow to fast to enhance the warning effect. At the same time, the buzzer emits an alarm sound at a specific frequency, the sound pressure level of which is precisely calibrated to ensure that it is sufficiently noticeable without causing excessive noise pollution. In other embodiments, the alarm information will also be displayed in real time on the display screen of the gate channel, including the title of the unborrowed book, location prompts, and solutions.

[0030] In another embodiment, a gate passage is blocked simultaneously with the alarm. The target gate passage is locked in the closed state by a gate release device to prevent readers from forcibly passing through with unborrowed books. Specifically, when abnormal pushing force is detected, the locking force is automatically increased to avoid injury to personnel. The alarm state remains in effect until authorized deactivation. Administrators can manually confirm and handle the situation through a verification interface on a dedicated terminal, recording a complete alarm event log, including trigger time, book information, passage location, and handling personnel, forming a traceable security event record.

[0031] As can be seen from the typical embodiments of this application, the technical solution of this application has many advantages, including but not limited to the following aspects: This application uses a human detection device to sense human movement within a target space, automatically acquiring the wireless sensing signal emitted by the book's RFID tag. Based on the signal characteristics of this wireless sensing signal, it determines the gate channel where the book is located. Then, it verifies the received book attribute information. When the book attribute information indicates that the book has been borrowed, it drives the corresponding gate release device to open the target gate channel, allowing the reader to pass smoothly. When the book attribute information indicates that the corresponding book has not been borrowed, it controls the alarm device corresponding to the gate channel where the book is located to issue an alarm reminder. At this time, it can accurately locate the specific gate channel of the unborrowed book, thereby identifying the reader carrying the unborrowed book.

[0032] Specifically, this application can directly lock the gate channel when it detects that a book has not been borrowed, avoiding the inefficiency of administrators having to check multiple channels when an alarm is issued, greatly saving management costs and time, and ensuring the safety and normal circulation of book resources.

[0033] Based on any embodiment of the method in this application, please refer to Figure 4 Determining the target gate channel where the corresponding book is located based on the wireless sensing signal includes: Step S5210: Determine the corresponding signal strength value and the unique identifier of the radio frequency identification device to which it belongs based on the wireless sensing signal; When a book passes through a turnstile, the wireless signal emitted by the RFID tag corresponding to the book is captured by the RFID devices installed on each turnstile. Each RFID device has a unique identifier to distinguish different turnstiles and turnstile equipment. The strength of the received wireless signal reflects the distance between the book and the RFID device and the clarity of the signal propagation. The higher the signal strength, the closer the book is to the RFID device, and the clearer the signal propagation. In one embodiment, the unique identifier of the RFID device is a string of numbers and letters. For example, the unique identifier of an RFID device might be "RFID-001-A," where "RFID-001" represents the device's serial number, and "A" represents the turnstile serial number. This identifier clearly indicates which RFID device on which gate captured the wireless signal.

[0034] Step S5220: When the wireless sensing signal is detected to be captured by the radio frequency identification device of a single gate channel, the gate channel to which the radio frequency identification device belongs is determined as the target gate channel where the book is located based on the unique identifier. When a book's wireless sensing signal is detected and captured only by an RFID device in a single gate channel, the gate channel containing the book is directly identified as the target gate channel based on the unique identifier of that RFID device. For example, when a reader carries a book through a turnstile, if the reader chooses to pass through the rightmost or leftmost gate channel, only the RFID device installed on the rightmost or leftmost gate can receive the wireless sensing signal emitted by the book. Since the rightmost or leftmost gate channel is located at the edge of the turnstile, the wireless sensing signal emitted by the book cannot be captured by RFID devices in other channels, or the signal strength is too weak to trigger other devices. In this case, the gate channel to which the receiving RFID device belongs is directly identified as the target gate channel containing the book based on the unique identifier of the RFID device that received the signal. For example, if the reader passes through the leftmost gate channel and the unique identifier of the RFID device corresponding to the received wireless sensing signal is "RFID-001-A", then channel A is identified as the target gate channel containing the book.

[0035] Step S5230: When the wireless sensing signal is detected to be captured by the radio frequency identification device of multiple gate channels, the gate channel to which the radio frequency identification device with the largest signal strength value belongs is determined as the target gate channel where the book is located.

[0036] When a book passes through a turnstile, the wireless signal emitted by its corresponding RFID tag is simultaneously captured by RFID devices in multiple channels. Since RFID signals have a limited propagation range, especially when channels are close together, the signal can be received by RFID devices in adjacent channels simultaneously. The actual gate channel location of the book is determined by measuring the signal strength of the received signals from each RFID device. Specifically, when the RFID tag's signal is captured by multiple RFID devices, the signal strength of each device is measured. For example, suppose that when a book passes through a turnstile, its RFID tag's signal is simultaneously captured by RFID devices in channels A and B. The signal strength in channel A is -35dB, while in channel B it is -45dB. In this case, the signal from channel A is stronger, indicating that the book is closer to channel A, and channel A is chosen as the target gate channel for the book.

[0037] In one embodiment, considering that signal strength can be affected by various factors, such as environmental interference and signal reflection, the received signal is sampled and analyzed multiple times. For example, the signal strength value is measured multiple times continuously within a preset time period, and its average value is calculated. If the results of multiple samplings show that the signal strength of channel A is the highest, then it is determined that the book is located in channel A.

[0038] In this embodiment, by combining signal strength and the unique identifier of the RFID device, the channel where the book is located can be quickly identified, and the actual position of the book can be accurately distinguished even when multiple channel signals overlap. This embodiment effectively avoids misjudgments caused by signal interference or close channel spacing.

[0039] Based on any embodiment of the method in this application, please refer to Figure 5 The process involves verifying the book attribute information obtained from the wireless sensing signal analysis. When the book attribute information indicates that the corresponding book has been borrowed, the corresponding gate release device is activated to open the target gate channel, including: Step S5310: Based on the status information of the anti-theft flag in the book attribute information, when the status information indicates that the corresponding book has been borrowed, drive the corresponding gate release device to open the target gate channel.

[0040] When the RFID device receives the wireless sensing signal emitted by the RFID tag of a book and parses it to obtain the book's attribute information, it checks the anti-theft flag bit in the book's attribute information. The anti-theft flag bit is a key information bit stored in the RFID tag of a book to identify the book's borrowing status, and its status information represents two situations: "borrowed" and "not borrowed".

[0041] Specifically, once a book is successfully borrowed, the library's borrowing system uses specific equipment to write the anti-theft flag to the book's RFID tag, setting its status to "borrowed." Conversely, when a book is not borrowed, the anti-theft flag's status remains "not borrowed." Therefore, by detecting the anti-theft flag's status, it's possible to quickly determine whether a book has gone through the normal borrowing process. When the anti-theft flag's status in the parsed book attribute information is "borrowed," it's determined that the book's borrowing procedure has been completed, and an opening command is sent to the corresponding gate release device. Upon receiving this command, the gate release device activates its internal drive mechanism, such as a motor, moving the gate baffle and opening the target gate channel, allowing the reader carrying the book to pass through smoothly.

[0042] In this embodiment, by directly checking the status information of the anti-theft tag, a decision can be made quickly without complex verification steps. This rapid response mechanism significantly improves the efficiency of readers passing through the gate, reduces waiting time, and optimizes the reader experience. Furthermore, since the status information of the anti-theft tag is directly written by the library system when books are borrowed, this verification method has high reliability and security, effectively preventing the possibility of unborrowed books being taken out.

[0043] Based on any embodiment of the method in this application, please refer to Figure 6 The process involves verifying the book attribute information obtained from the wireless sensing signal analysis. When the book attribute information indicates that the corresponding book has been borrowed, the corresponding gate release device is activated to open the target gate channel, including: Step S5320: Based on the unique book identifier in the book attribute information, determine from the book database whether there is a matching valid borrowing information for the unique book identifier; When the RFID device receives the wireless sensing signal emitted by the RFID tag of a book and parses it to obtain the book's attribute information, it further verifies the book's borrowing status using the unique identifier within the book's attribute information. Specifically, it uses the unique identifier in the book's attribute information to interactively query the library's book database to determine if there is matching valid borrowing information for the book. Specifically, firstly, the unique identifier of the book is extracted from the parsed book attribute information. This unique identifier is a pre-set unique code in the RFID tag used to accurately distinguish each book. Then, through a pre-set communication interface, the unique identifier is sent to the book database for querying. The book database is a system used by the library to store all book information, including basic information and detailed records such as borrowing status for each book. During the query process, a query request is constructed, using the unique identifier of the book as a key parameter, to retrieve matching borrowing records from the book database. If the query results show one or more valid borrowing records, and these records indicate that the book has been borrowed, the book's borrowing status is determined to be "borrowed".

[0044] In some embodiments, other relevant information can be combined for a comprehensive assessment. For example, other factors such as the reader's identity information and borrowing time can be considered to more comprehensively verify the borrowing status of the book.

[0045] Step S5330: If it exists, determine that the book attribute information indicates that the corresponding book has been borrowed, and generate a gate opening command; Once the book database query confirms the existence of valid borrowing information matching the book's unique identifier, the gate opening instruction generation stage begins. In this stage, a specific gate opening instruction is generated according to preset logical rules. This gate opening instruction contains signals with specific control parameters to instruct the gate release device to perform the opening operation. The gate generation instruction will clearly specify the gate channel to be opened, ensuring that only the channel where the reader with the borrowed book is located will be opened.

[0046] In some embodiments, a short delay mechanism is set so that the gate opening operation is not executed immediately after the gate opening command is generated, but a preset time interval is required. This delay mechanism is used to provide additional time to complete the final verification and inspection, ensuring the accuracy and security of the entire operation process.

[0047] Step S5340: Based on the location information of the target gate channel, send the gate opening command to the corresponding gate release device, and control the gate release device to unlock and open the target gate channel.

[0048] Based on the location information of the target gate channel, a gate opening command is sent to the corresponding gate release device to control the device to unlock and open the target gate channel. Specifically, it is necessary to accurately obtain the location information of the target gate channel. This location information is recorded in the database during initialization, and each gate channel has a unique identifier to distinguish different channels. In one embodiment, when it is determined that a specific gate channel needs to be opened, the location information of that gate channel is retrieved from the database, including the channel number, physical location, and the interface information of the corresponding gate release device. After obtaining the location information of the target gate channel, detailed control commands are constructed based on this information. These control commands not only include the command to open the gate but also the specific location information of the target gate channel, ensuring that the commands are correctly sent to the corresponding gate release device.

[0049] Specifically, control commands are sent to the corresponding gate release device via a pre-defined communication link. This communication link can be a wired network, such as Ethernet, or a wireless network, such as Wi-Fi or Bluetooth, depending on the actual deployment. During the command transmission process, various technical means are employed to ensure the quality of command transmission. For example, error detection and correction algorithms are used to prevent errors during data transmission, and encryption technology is used to protect the security of the commands and prevent unauthorized access and tampering.

[0050] In this embodiment, by accurately obtaining the location information of the target gate channel and sending the gate opening command to the corresponding gate release device, the opening of a specific gate channel can be precisely controlled, ensuring that only the channel where the reader carrying the borrowed book is located will be opened.

[0051] Based on any embodiment of the method in this application, please refer to Figure 7 The process involves verifying the book attribute information obtained from the wireless sensing signal analysis. When the book attribute information indicates that the corresponding book has been borrowed, the corresponding gate release device is activated to open the target gate channel, including: Step S6100: Monitor the signal strength value of the corresponding wireless sensing signal of the book in real time; After successfully verifying the book's attribute information and triggering the corresponding gate release device to open the target gate channel, the signal strength of the wireless sensing signal is monitored in real time. Specifically, the RFID device continuously measures the strength of the received wireless sensing signal and transmits this data to the control center in real time. The signal strength value reflects the distance between the book's RFID tag and the RFID device, as well as the quality of signal propagation. The signal strength value is higher when the book is close to the RFID device, and gradually decreases as the book moves away from the RFID device.

[0052] Step S6200: When the signal strength value is less than a preset strength threshold, control the gate release device to close the target gate channel.

[0053] When the signal strength value of the corresponding wireless sensing signal of the book is less than the preset strength threshold, it indicates that the book has left the effective monitoring range of the radio frequency identification device, that is, the reader has passed through the target gate channel. At this time, the gate release device is controlled to close the target gate channel.

[0054] In some embodiments, the monitored signal strength value is sampled multiple times to ensure that the signal strength value is less than the preset strength threshold and is not caused by short-term signal fluctuations or interference. If multiple sampling results show that the signal strength value is continuously lower than the threshold, it will be determined that the reader has passed through the target gate channel, and at this time the gate release device will be controlled to close the target gate channel.

[0055] In this embodiment, it is possible to ensure that the target gate channel can be closed in a timely manner after the book leaves the effective monitoring range or the reader passes through the target gate channel, thereby improving the reliability and security of the entire book anti-theft system and providing readers with a more convenient and efficient borrowing experience.

[0056] Based on any embodiment of the method in this application, please refer to Figure 8 The method acquires the wireless sensing signals emitted by the RFID tags of books received by the RFID devices installed on each gate channel, including: Step S7100: Control the antenna arrays located on multiple gate channels to be polled and activated. When the antenna array of the current gate channel is polled and activated, control the corresponding electronic switch circuit to close and control the corresponding electronic switch circuits of other gate channels to open, thereby stimulating the antenna array of the current gate channel to transmit radio frequency signals and receive wireless sensing signals emitted by the book radio frequency identification tag, while suppressing signal interference caused by the operation of other antenna arrays. An antenna array polling activation mechanism is employed to ensure that the RFID device can efficiently and accurately receive the wireless sensing signals emitted by the book RFID tags, while avoiding signal interference between multiple antenna arrays. Specifically, each gate channel is equipped with an antenna array consisting of multiple regularly arranged antennas. In one embodiment, each antenna in the array is composed of a coil, and the open-circuit design of the coil allows the antenna's operating state to be controlled by an electronic switching circuit. By controlling the electronic switching circuit of this channel to close, the antenna array can transmit radio frequency signals and receive the wireless sensing signals emitted by the book RFID tags. At the same time, the electronic switching circuits of other gate channels are kept open, thereby suppressing the operation of other antenna arrays and preventing their transmitted signals from interfering with the signals of the currently active antenna array.

[0057] By activating the antenna array of each gate channel in sequence, the wireless sensing signals emitted by the RFID tags of books on each channel can be acquired one by one, without signal overlap or interference caused by multiple antenna arrays working at the same time.

[0058] Step S7200: Poll the operation of multiple antenna arrays to obtain the wireless sensing signals emitted by the book RFID tags received by the antenna array on each gate channel.

[0059] Multiple antenna arrays are controlled by polling to acquire the wireless sensing signals emitted by the RFID tags on the books received by the antenna arrays on each gate channel. The control center activates the antenna arrays of each gate channel sequentially according to a preset order. When the antenna array of the current gate channel is activated, the corresponding electronic switch circuit is closed, while the electronic switch circuits of other gate channels are opened to ensure that only the currently activated antenna array can transmit and receive signals, thereby avoiding signal interference caused by the operation of other antenna arrays. Specifically, when the antenna array of a certain gate channel is polled and activated, an excitation signal is sent to that antenna array, causing it to transmit radio frequency signals. These radio frequency signals will excite the RFID tags on the books to emit wireless sensing signals. At the same time, the antenna arrays of other gate channels are kept silent to avoid interference between their transmitted signals and the signals of the currently activated antenna array.

[0060] In one embodiment, if the received wireless sensing signal has a weak signal strength or strong interference, various technical means are employed. For example, the transmit power of the antenna array is adjusted to enhance the signal strength; or more advanced signal processing algorithms, such as adaptive filtering algorithms, are used to better remove interference components from the signal.

[0061] In this embodiment, multiple antenna arrays are controlled by polling. The wireless sensing signals received by the antenna array on each gate channel are acquired sequentially, ensuring that only one antenna array is active at any given time. When an antenna array is activated, it transmits radio frequency signals and receives wireless sensing signals from the book RFID tag, while the other antenna arrays remain silent. This polling activation and electronic switching circuit control ensure that each channel's antenna array transmits and receives signals independently, thus avoiding signal overlap and interference problems that occur when multiple channels operate simultaneously.

[0062] Based on any embodiment of the method in this application, please refer to Figure 9 Determining the target gate channel where the corresponding book is located based on the wireless sensing signal includes: Step S5240: When the wireless sensing signal received by the radio frequency identification device is characterized as being emitted by the radio frequency identification tags of multiple books within a preset time period, determine the spatial distribution characteristics of the radio frequency identification tags of each book. When multiple RFID tags on books simultaneously emit wireless sensing signals, the RFID device receives multiple signals. The strength and propagation direction of these wireless signals are influenced by the spatial position and arrangement of the books. Based on the analysis of these wireless signals, the spatial distribution characteristics of the RFID tags for each book are determined. Specifically, when the RFID device receives multiple wireless sensing signals, it first records key parameters such as the strength, frequency, and phase of each signal. These parameters provide important information about the signal propagation path and the book's position. For example, signal strength reflects the distance between the book and the RFID device, and the phase difference provides clues about the relative positions of the books. In one embodiment, based on these parameters, a spatial distribution model is constructed to describe the spatial relationship between the RFID tags of each book, thereby determining the spatial distribution characteristics of the RFID tags for each book.

[0063] Step S5250: Determine the relative distance between each pair of RFID tags based on the spatial distribution characteristics. When the maximum relative distance exceeds a preset first distance threshold, identify the RFID tag closest to the RFID device as the target RFID tag. Based on the spatial distribution characteristics recorded in the previous step, the relative distance between each pair of RFID tags is calculated. Specifically, one approach is to utilize a signal strength attenuation model, which is based on the relationship between signal strength and distance, assuming that signal strength decreases with increasing distance. For example, a free-space propagation model can be used, which shows that signal strength is inversely proportional to the square of the distance. By measuring the signal strength of the two tags and combining this with known signal transmit power and antenna gain, the distance between the two tags can be estimated. Another approach is to utilize the phase difference of the signals. When two induced signals arrive at the RFID device simultaneously, the phase difference can determine information about the signal propagation path length. By measuring the phase difference and combining it with the signal wavelength, the relative distance between the two tags can be calculated.

[0064] The relative distances between all book RFID tag pairs are calculated and recorded to determine which RFID tags are adjacent and which are separate. If the relative distance between any two tags exceeds a preset first distance threshold, these tags are considered spatially separate. For example, if the preset first distance threshold is 1 meter, and the calculated relative distance between two tags is 1.5 meters, then the books corresponding to these two tags can be considered as being carried by different readers. After determining which tags are separate, the RFID tag closest to the RFID device is further identified by selecting the minimum distance value from the recorded distance values; this tag is the one closest to the RFID device.

[0065] Step S5260: The books corresponding to the RFID tags whose relative distance to the target RFID tag is less than a preset second distance threshold, and the books corresponding to the target RFID tags are taken as target books, and the target gate channel where the target books are located is determined, wherein the first distance threshold is greater than the second distance threshold.

[0066] In the previous step, the RFID tag closest to the RFID device was identified as the target RFID tag. Based on the relative distances between other RFID tags and the target RFID tag, these distance values ​​are compared with a preset second distance threshold. The preset second distance threshold defines which books can be considered "adjacent" to the target book, i.e., carried by the same reader. For example, if the preset second distance threshold is 0.1 meters, then all books corresponding to RFID tags with a relative distance of less than 0.1 meters from the target RFID tag are considered target books, where the target books are determined to be carried by the same reader. After determining all target books, the gate channel where these target books are located is further determined. The above embodiment has explained how to determine the gate channel where the book is located, and will not be repeated here. In this step, the gate channel where the target RFID tag corresponds to the book is located is the gate channel where the target book is located.

[0067] In this embodiment, by calculating the relative distance between multiple books sensed by the radio frequency identification device, it is possible to accurately distinguish the books carried by different readers and determine the target gate channel as the channel corresponding to the target book, so as to ensure that the alarm is only for the books actually carried by the reader who passed through the gate channel this time.
