Description

Technical Field

[0001] The present invention relates to the technical field of library management, and in particular to a self-service book borrowing and returning management method and system based on NFC technology. Background Art

[0002] With the rapid development of the information society, digital technology has penetrated into all aspects of daily life, from electronic payment to smart home, to smart transportation and health management. The popularization and application of technology has greatly improved the efficiency of social operation. As an important place for knowledge transmission and cultural dissemination, libraries are also gradually facing the pressure and challenges of technological innovation. In this context, intelligent and automated borrowing systems have become a major trend in the development of libraries. Especially in modern society with accelerated urbanization and increased population density, the demand for library borrowing is growing, and the traditional manual borrowing management model can no longer meet the needs of modern readers for convenience and efficiency. Therefore, how to improve library management efficiency, improve borrowing experience and strengthen resource utilization through technical means has become an urgent problem to be solved. At the same time, with the continuous maturity and popularization of NFC technology, with the help of this efficient, low-power and easy-to-integrate wireless communication technology, the library's borrowing and returning management has a more intelligent and automated upgrade space. By introducing NFC technology, libraries can realize the automation of book borrowing and returning and the real-time update and sharing of book information, so as to better adapt to the modern society's demand for efficient public resource management.

[0003] Although the traditional library lending system has gradually achieved digital transformation, there are still many efficiency bottlenecks. At present, many libraries still use manual registration and traditional barcode scanning to borrow and return books, which not only increases the workload of staff, but also easily leads to inaccurate or missing book information due to information entry errors and equipment failures. At the same time, due to the lack of dynamic analysis and personalized management of readers' borrowing behavior, many libraries fail to set reasonable borrowing restrictions based on readers' credit status, resulting in some readers with poor credit frequently borrowing books but not returning them on time, further increasing the management burden. This situation not only affects the reasonable allocation of library resources, but also reduces the readers' user experience, and may even cause readers to be dissatisfied with and complain about the borrowing system. Therefore, there is still room for improvement in the information processing speed and data accuracy in the borrowing process, especially when dealing with high-concurrency borrowing scenarios, which may lead to low efficiency in borrowing and returning books, increase the burden on readers and library management systems, and make it difficult to meet the increasing demand for borrowing and returning books. It also fails to fully consider the compliance of book borrowing and the credit management of readers in the borrowing process. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a self-service book borrowing and returning management method and system based on NFC technology, which solves the problems in the above-mentioned background technology.

S2, the client device communicates with the NFC tag on the book in close proximity through the NFC protocol, and transmits the communication signal to the library management system through the wireless network for verification, and extracts the book borrowing and returning information related to the reader's identity, and processes it dimensionlessly to obtain the book borrowing data set; S3, calculate based on the obtained book borrowing data set, obtain the borrowing reputation score index jpf, and evaluate the reputation with the first reputation score threshold A and the second reputation score threshold B. When the reader meets the reputation condition, set the borrowing quantity and borrowing time limit according to the reader's reputation score, and then notify the book borrowing information according to the book borrowing status information and the book borrowing and returning information in the reader's account, generate the borrowing record and update the inventory information of the library management system; S4. When a reader returns a book, the NFC tag embedded in the book is automatically scanned and read by the equipped NFC reader, and data is coordinated with the library management system and the reader's client device to obtain the book return information. After dimensionless processing, the return compliance data set is obtained. Based on the return compliance data set, summary calculations are performed to obtain the book return compliance coefficient ghg to conduct real-time evaluation of readers' non-compliant borrowing behaviors, and the evaluation results are recorded.

[0006] Preferably, said S1 includes S11 and S12; S11. An NFC chip tag compatible with the book's appearance design is installed on the inner side of the spine of each book. The NFC tag contains a micro integrated circuit IC for storing book information, including the book's unique identifier ID, title, international standard book number ISBN, author and borrowing status. The book information and the ID number of the NFC tag are then stored in the library management system. S12. The reader uses a client device with NFC support, installs a borrowing and returning application compatible with the library management system, and enters the reader information to create a personal account. The reader information includes name, identity and contact information. After creating the personal account, the user is authorized to log in using a PIN code authentication method, and a dynamic verification code is generated through SMS and application to increase the security level. The code is then associated with the personal account in the library management system through a wireless network. The library management system generates a unique client device identifier ID for each reader.

The library management system performs reader identity authentication through the NFC device and the borrowing and returning application. After successful authentication, the library management system loads a personalized borrowing and returning interface according to the reader's identity and extracts book borrowing and returning information related to the reader's identity, wherein the book borrowing and returning information includes a list of borrowed books, borrowing history records, and overdue records; S22, performing dimensionless processing on the obtained book borrowing information to obtain a book borrowing data set; The book borrowing dataset includes the number of books returned on time nr, the total borrowing time tr, the number of overdue days do, the registered borrowing time tb and the number of damaged books fd.

[0008] Preferably, said S3 includes S31 and S32; S31, performing summary calculation based on the obtained book borrowing data set to obtain a borrowing credit score index jpf; The borrowing credit score index jpf is calculated by the following formula: .

[0009] Preferably, the S32 includes S321 and S322; S321. Collect the historical book borrowing data and comprehensive credit scores of all library borrowers in the first quarter cycle, sort the credit scores of all borrowers from low to high, use statistical methods to perform quantile analysis, obtain the percentile of the borrower's credit score, divide it into four equal parts of 25th percentile, 50th percentile and 75th percentile according to the score distribution of the borrower, and preset the credit score of the 25th percentile borrower as the first credit score threshold A, and the credit score of the 75th percentile borrower as the second credit score threshold B, and then evaluate the borrower's credit with the obtained borrowing credit score index jpf. The specific evaluation plan is as follows; When the borrowing credit score index jpf is less than the first credit score threshold A, it means that the reader's credit value is unqualified, and the reader is added to the blacklist, and the client device displays that the borrowing of books is prohibited; When the first credit score threshold A≤borrowing credit score index jpf≤the second credit score threshold B, it means that the reader has overdue behavior, and the number and duration of borrowed books are restricted; When the borrowing credit score index jpf> the second credit score threshold B, it means that the reader has no overdue behavior, has a good credit, and maintains normal monitoring.

[0010] Preferably, S322, when the reader meets the credit condition, the library management system sends a borrowing signal to the client device through the wireless network, and reads the book information and borrowing status information on the NFC tag. When the book is borrowed, the library management system sends a message to the reader's client device that "this book has been borrowed, please reselect other books". When the book is borrowed, the library management system matches the identity information in the reader's device with the reader's account information in the library management system, and reads the book borrowing and returning information in the reader's account. When there is a problem with the reader's account, the library management system informs the reader through a feedback mechanism that the book cannot be borrowed, and provides prompts and suggestions; When there is no problem with the reader's account, the library management system sets different borrowing quantity limits and borrowing time limits according to the reader's credit score, and records and confirms the reader's borrowing information, which includes the borrowing time, due date, name of the borrowed book, number, book barcode, reader ID and borrowing status; The loan quantity jys and loan duration jsc adjustment mechanism are adjusted by the following formula; , , where sx represents the upper limit of the number of books currently borrowed by the reader, and jy represents the upper limit of the current borrowing time of the reader; When the reader completes the book borrowing operation, a book borrowing record is generated and the inventory information of the library management system is updated, and the status of the book is updated to borrowed. The library management system sends the borrowing information to the reader's client device via SMS notification, and displays the borrowing success, borrowing time, due date, name and number of the borrowed book, and then re-evaluates the reader's credit score, updates their borrowing permissions and restrictions in real time, and feedbacks the current borrowing restrictions and borrowing status through the client device.

[0011] Preferably, S4 includes S41, S42 and S43; S41. After the reader has borrowed the book, the NFC technology is used to continuously track the location and status of the book during the borrowing period. If the book is not returned after the specified time, the library management system automatically sends a reminder to the borrower via SMS; S42. When a reader returns a book, the borrowed book is placed in the designated return area of ​​the book. The area is equipped with an NFC card reader. The NFC card reader automatically scans and reads the NFC tag embedded in the book. After successfully reading the book tag, the library management system uses the unique identifier to find the corresponding borrowing record and matches it with the tag information. The library management system, the NFC tag and the reader's client device perform data collaboration to obtain the reader's book return information, and perform dimensionless processing to obtain a return compliance data set, which includes the number of books returned on time nr, the total number of books borrowed js, the number of overdue days do, the number of borrowed days jt, the number of books returned without damage wh and the total number of books borrowed zs; When the library management system confirms that the book matches the borrowing record, it immediately sends confirmation information of the successful return to the reader's client device, cancels the borrowing record in the reader's account, marks the book as returned, updates the reader's borrowing history, records the return time and date, changes the book's status to available for borrowing in the library management system, and updates the book's location and quantity.

[0012] Preferably, the S43 includes S431 and S432; S431. Analyze the compliance of readers' book returns based on the obtained return compliance data set, and construct a compliance formula through the library management system. When readers return books, input the obtained reader return compliance data set into the compliance formula for summary calculation to obtain the book return compliance coefficient ghg; The book return compliance coefficient ghg is calculated by the following formula; ; In the formula, e represents the exponential function, k1 represents the correction constant for adjusting the impact of overdue days on the compliance assessment of book returns, and k2 represents the correction constant for adjusting the interaction effect between overdue days and book integrity.

[0013] Preferably, S432, using the obtained book return compliance coefficient ghg to evaluate the reader's non-compliant borrowing behavior in real time, and record the evaluation results. The specific evaluation scheme is as follows; When the book return compliance coefficient ghg≥1, it means that the reader returns the book on time and the book is in good condition, maintains a good borrowing record, and is evaluated by S3 for credit score; When the book return compliance coefficient ghg is less than 1, it means that the reader does not return the book on time and the book is damaged, which is a non-compliant behavior. The credit score is evaluated through S3, and the reader is reminded of the borrowing violation through SMS to improve the borrowing behavior.

[0014] A set-top box user behavior intelligent collection and analysis system, including a device association module, an information verification module, a reputation analysis module and a compliance analysis module; The device association module is used to install an NFC chip tag on the inside of the book spine to store book information. Readers use a client device with NFC support to create a personal account, and then associate it with the personal account in the library management system through a wireless network; The information verification module connects the client device and the NFC tag on the book through the NFC protocol, and then transmits the communication signal to the library management system through the wireless network for verification, and extracts the book borrowing and returning information related to the reader's identity, performs dimensionless processing, and obtains the book borrowing data set; The reputation analysis module is used to calculate based on the acquired book borrowing data set, obtain the borrowing reputation score index jpf, and perform reputation evaluation with the first reputation score threshold A and the second reputation score threshold B. When the reader meets the reputation condition, the borrowing quantity and borrowing time limit are set according to the reader's reputation score, and then the book borrowing information is notified according to the book borrowing status information and the book borrowing and returning information in the reader's account, and the borrowing record is generated and the inventory information of the library management system is updated; The compliance analysis module is used to automatically scan and read the NFC tag embedded in the book through the equipped NFC card reader when the reader returns the book, and to coordinate data with the library management system and the reader's client device to obtain the book return information. After dimensionless processing, the return compliance data set is obtained, and summary calculations are performed based on the return compliance data set to obtain the book return compliance coefficient ghg to evaluate the reader's non-compliant borrowing behavior in real time, and record the evaluation results.

[0015] The present invention provides a self-service book borrowing and returning management method and system based on NFC technology. It has the following beneficial effects: (1) This method significantly improves the efficiency and convenience of the book borrowing process by combining wireless communication and smart devices. An NFC chip tag is installed on the inner spine of each book, which stores the book's unique identifier ID, title, International Standard Book Number (ISBN), author, and borrowing status. Readers create a personal account through an NFC-enabled client device, enter their identity information and authenticate, and then associate it with their personal account in the library management system. When borrowing a book, readers only need to bring the client device close to the NFC tag on the book to automatically read the book information and complete the borrowing operation. This self-service borrowing and returning mode greatly simplifies the traditional manual borrowing and returning process and improves the automation and intelligence level of library management.

[0016] (2) Based on the borrowing history of readers, this method extracts the book borrowing and returning information related to the reader's identity, performs dimensionless processing, and generates a book borrowing dataset. On this basis, the reader's borrowing credit score index jpf is calculated and compared with the first credit score threshold A and the second credit score threshold B, so as to evaluate the reader's borrowing credit. When the borrowing credit score index jpf is lower than the first credit score threshold A, the system will put it on the blacklist and prohibit borrowing books; when the borrowing credit score index jpf is between the first credit score threshold A and the second credit score threshold B, the borrowing quantity and borrowing time will be restricted; and when the borrowing credit score index jpf is higher than the second credit score threshold B, it means that the reader has a good credit and will be allowed to enjoy more borrowing rights. This credit evaluation mechanism not only promotes readers to comply with borrowing regulations and reduce the occurrence of overdue and damaged books, but also enhances the accuracy and flexibility of library management.

[0017] (3) This method also has the function of real-time tracking of book return compliance. When a reader returns a book, the NFC card reader automatically scans and reads the NFC tag on the book. The library management system compares the tag information with the reader's borrowing record to confirm the return status of the book. The book return compliance coefficient ghg is calculated based on the book return compliance data set. When the book return compliance coefficient ghg is greater than or equal to 1, it means that the book is returned on time and in good condition, and the reader's credit score will be improved; when the book return compliance coefficient ghg is less than 1, it means that there is overdue or damaged books, which will remind readers to improve their borrowing behavior and may affect their credit score. Through this mechanism, the library can monitor the reader's borrowing compliance in real time and deal with borrowing violations in a timely manner. At the same time, it can also effectively maintain the good status of library resources and further improve the library's service quality and management efficiency. Through the combination of intelligent equipment and data analysis, this method not only simplifies the library's borrowing process and improves the reader experience, but also effectively optimizes resource management and supervision of borrowing behavior. This innovative management approach enables the library to operate more efficiently. At the same time, through real-time monitoring and scoring mechanisms, it improves readers' borrowing compliance and the library's service quality, and promotes the library management model to develop in a more modern and refined direction.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1 The present invention provides a self-service book borrowing and returning management method based on NFC technology. To achieve the above purpose, the present invention is implemented through the following technical scheme: comprising the following steps: S1. Install an NFC chip tag on the inside of the book spine to store book information. Readers use NFC-enabled client devices to create personal accounts, and then associate them with personal accounts in the library management system through wireless networks. S2, the client device communicates with the NFC tag on the book in close proximity through the NFC protocol, and transmits the communication signal to the library management system through the wireless network for verification, and extracts the book borrowing and returning information related to the reader's identity, and processes it dimensionlessly to obtain the book borrowing data set; S3, calculate based on the obtained book borrowing data set, obtain the borrowing reputation score index jpf, and evaluate the reputation with the first reputation score threshold A and the second reputation score threshold B. When the reader meets the reputation condition, set the borrowing quantity and borrowing time limit according to the reader's reputation score, and then notify the book borrowing information according to the book borrowing status information and the book borrowing and returning information in the reader's account, generate the borrowing record and update the inventory information of the library management system; S4. When a reader returns a book, the NFC tag embedded in the book is automatically scanned and read by the equipped NFC reader, and data is coordinated with the library management system and the reader's client device to obtain the book return information. After dimensionless processing, the return compliance data set is obtained. Based on the return compliance data set, summary calculations are performed to obtain the book return compliance coefficient ghg to conduct real-time evaluation of readers' non-compliant borrowing behaviors, and the evaluation results are recorded.

[0021] In this embodiment, by installing an NFC chip tag on the inside of the spine of each book and binding the book information to the reader's personal account, the seamless connection between the book information and the reader's identity is achieved. The reader creates a personal account through a client device that supports the NFC protocol and associates it with the library management system through a wireless network. This process effectively converts the manual operation in the traditional borrowing process into a fast automated operation. Compared with the traditional library borrowing method, this method avoids the cumbersome steps of manual code scanning, registration and information verification, and improves the convenience and accuracy of borrowing. An intelligent credit scoring mechanism is introduced in the borrowing process. By collecting and analyzing the reader's borrowing behavior, the borrowing credit scoring index jpf is calculated. This mechanism combines the reader's historical borrowing data, evaluates the reader's borrowing credit, and sets limits on the number of borrowings and the length of borrowing time. Through this credit-based evaluation method, the borrowing authority can be automatically adjusted to ensure that readers who abide by the borrowing rules can enjoy greater borrowing freedom, while readers with poor credit are subject to appropriate restrictions. Compared with the traditional manual approval process, this mechanism can more efficiently manage readers' borrowing behavior and effectively reduce the occurrence of bad behaviors such as overdue and damaged books. In the book return process, the system realizes automatic return verification through the application of NFC technology, and evaluates the reader's return behavior in real time by calculating the book return compliance coefficient ghg. By dimensionless processing of return information, it can evaluate whether readers return books on time and whether there are non-compliant behaviors such as damage, and through the real-time feedback mechanism, it helps library managers to timely discover and deal with illegal borrowing behaviors. This method not only reduces the time cost of manual inspection, but also improves the utilization rate of library resources. Compared with the traditional manual recording and verification method, this method has significant advantages in accuracy and real-time performance, thereby further improving the management efficiency and service quality of the library. The automation of the borrowing and returning process not only reduces the interaction time between readers and library staff, but also improves the accuracy and efficiency of operations. At the same time, the introduction of borrowing credit scoring and return compliance evaluation enables the library to manage borrowing behavior more accurately and ensure the rational allocation and use of resources. Compared with the traditional manual management method, this solution based on NFC technology significantly improves the library's operating efficiency and service quality, can meet the needs of modern information management, and promotes the development of library management in a more intelligent and refined direction.

[0022] Example 2 This embodiment is explained in Example 1, please refer to Figure 1 , specifically: the S1 includes S11 and S12; S11. An NFC chip tag compatible with the book's appearance design is installed on the inner side of the spine of each book. The NFC tag contains a micro integrated circuit IC for storing book information, including the book's unique identifier ID, title, international standard book number ISBN, author and borrowing status. The book information and the ID number of the NFC tag are then stored in the library management system. S12. The reader uses a client device with NFC support, installs a borrowing and returning application compatible with the library management system, and enters the reader information to create a personal account. The reader information includes name, identity and contact information. After creating the personal account, the user is authorized to log in using a PIN code authentication method, and a dynamic verification code is generated through SMS and application to increase the security level. The code is then associated with the personal account in the library management system through a wireless network. The library management system generates a unique client device identifier ID for each reader.

[0023] In this embodiment, by installing an NFC chip tag compatible with the book's appearance design on the inner side of the inner spine of each book, an intelligent combination of book information and borrowing management is achieved. Each NFC tag stores the book's unique identifier, title, ISBN, author and borrowing status, making the book borrowing process more efficient and accurate. At the same time, readers create personal accounts through NFC-enabled client devices, and ensure account security through multiple verification methods such as PIN code authentication, SMS and dynamic verification codes. Through the wireless network, the reader's account is associated with the personal account in the library management system, and a unique client device identifier ID is assigned to each reader, realizing the unique identification and management of the reader's identity. This process not only simplifies the operation process of book borrowing, but also improves the convenience and safety of borrowing through intelligent identity authentication and book information management. Compared with the traditional manual registration and verification process, this method greatly reduces the occurrence of human errors, improves the intelligence level of the management system, and provides a more accurate and efficient borrowing management method for the library.

[0024] Example 3 This embodiment is explained in Example 2. Please refer to Figure 1 , specifically: S2 includes S21 and S22; S21, the reader brings the client device close to the NFC tag on the book, performs close-range communication with the NFC tag on the book through the NFC protocol, and transmits the communication signal to the library management system through the wireless network. The library management system performs reader identity authentication through the NFC device and the borrowing and returning application. After successful authentication, the library management system loads a personalized borrowing and returning interface according to the reader's identity and extracts book borrowing and returning information related to the reader's identity, wherein the book borrowing and returning information includes a list of borrowed books, borrowing history records, and overdue records; S22, performing dimensionless processing on the obtained book borrowing information to obtain a book borrowing data set; The book borrowing dataset includes the number of books returned on time nr, the total borrowing time tr, the number of overdue days do, the registered borrowing time tb and the number of damaged books fd.

[0025] In this embodiment, the reader brings the client device close to the NFC tag on the book, quickly completes the identity authentication through the NFC protocol, loads a personalized borrowing and returning interface, and automatically extracts the borrowing information related to the reader's identity. This process greatly simplifies the traditional book borrowing process, does not require manual intervention, avoids possible identity verification errors and data delays, and thus improves the convenience and accuracy of the book borrowing operation. The book borrowing data is converted into a unified borrowing data set through dimensionless processing, making the evaluation of borrowing behavior more comprehensive and accurate. Through this automated data analysis and processing, the system can evaluate and track readers' borrowing behavior in real time, providing a reliable basis for subsequent decisions such as borrowing restrictions and credit evaluation. Overall, this NFC-based intelligent borrowing and returning process not only improves operational efficiency, but also ensures the real-time and accuracy of borrowing information, helps to better manage book resources and reader behavior, and improves the library's management level and user experience.

[0026] Example 4 This embodiment is explained in Example 3, please refer to Figure 1 , specifically: S3 includes S31 and S32; S31, performing summary calculation based on the obtained book borrowing data set to obtain a borrowing credit score index jpf; The borrowing credit score index jpf is calculated by the following formula: .

[0027] The S32 includes S321 and S322; S321. Collect the historical book borrowing data and comprehensive credit scores of all library borrowers in the first quarter cycle, sort the credit scores of all borrowers from low to high, use statistical methods to perform quantile analysis, obtain the percentile of the borrower's credit score, divide it into four equal parts of 25th percentile, 50th percentile and 75th percentile according to the score distribution of the borrower, and preset the credit score of the 25th percentile borrower as the first credit score threshold A, and the credit score of the 75th percentile borrower as the second credit score threshold B, and then evaluate the borrower's credit with the obtained borrowing credit score index jpf. The specific evaluation plan is as follows; When the borrowing credit score index jpf is less than the first credit score threshold A, it means that the reader's credit value is unqualified, and the reader is added to the blacklist, and the client device displays that borrowing books is prohibited; When the first credit score threshold A≤borrowing credit score index jpf≤the second credit score threshold B, it means that the reader has overdue behavior, and the number and duration of borrowed books are restricted; When the borrowing credit score index jpf> the second credit score threshold B, it means that the reader has no overdue behavior, has a good credit, and maintains normal monitoring.

[0028] S322. When the reader meets the credit condition, the library management system sends a borrowing signal to the client device through the wireless network, and reads the book information and borrowing status information on the NFC tag. When the book is borrowed, the library management system sends a message to the reader's client device saying "This book has been borrowed, please select another book". When the book is borrowed, the library management system matches the identity information in the reader's device with the reader's account information in the library management system to ensure the uniqueness of the identity, and reads the book borrowing and returning information in the reader's account to check whether the borrowing limit is exceeded, whether there are overdue books, and whether there is an outstanding balance. When there is a problem with the reader's account, the library management system informs the reader through the feedback mechanism that the book cannot be borrowed, and provides prompts and suggestions. When there is no problem with the reader's account, the library management system sets different borrowing quantity limits and borrowing time limits according to the reader's credit score, and records and confirms the reader's borrowing information, which includes the borrowing time, due date, name of the borrowed book, number, book barcode, reader ID and borrowing status; The loan quantity jys and loan duration jsc adjustment mechanism are adjusted by the following formula; , , where sx represents the upper limit of the number of books currently borrowed by the reader, and jy represents the upper limit of the current borrowing time of the reader; When the reader completes the book borrowing operation, a book borrowing record is generated and the inventory information of the library management system is updated, and the status of the book is updated to borrowed. The library management system sends the borrowing information to the reader's client device via SMS notification, and displays the borrowing success, borrowing time, due date, name and number of the borrowed book, and then re-evaluates the reader's credit score, updates their borrowing permissions and restrictions in real time, and feedbacks the current borrowing restrictions and borrowing status through the client device.

[0029] In this embodiment, by summarizing and calculating the reader's book borrowing data set, the borrowing credit score index jpf is obtained, which ensures that the library can set personalized borrowing permissions according to the credit status of each reader. This data-driven evaluation method can dynamically adjust the borrowing quantity and borrowing time limit, avoid excessive borrowing or improper borrowing, and improve the fairness and utilization of book resources. Secondly, by setting a clear first credit score threshold A and a second credit score threshold B, the library can automatically identify and restrict readers with more overdue or bad borrowing behaviors, thereby effectively reducing the risk of overdue and damaged books. Compared with the traditional model that relies on manual management, the application of NFC technology makes this process more efficient, accurate and real-time, and the management of readers' borrowing behavior can be automated, greatly reducing the workload of manual review. In addition, through timely feedback, the library can monitor the reader's borrowing status and credit in real time during the borrowing process, ensure a smooth borrowing experience, and help readers improve their own borrowing compliance. This method not only optimizes the borrowing process and improves management efficiency, but also enhances the service quality of the library, making the entire borrowing process more intelligent and personalized.

[0030] Example 5 This embodiment is explained in Example 4. Please refer to Figure 1 , specifically: the S4 includes S41, S42 and S43; S41. After the reader has borrowed the book, the NFC technology is used to continuously track the location and status of the book during the borrowing period. If the book is not returned after the specified time, the library management system automatically sends a reminder to the borrower via SMS; S42, when the reader returns the book, the borrowed book is placed in the designated return area of ​​the book, which is equipped with an NFC card reader. The NFC card reader automatically scans and reads the NFC tag embedded in the book. After successfully reading the book tag, the library management system uses the unique identifier to find the corresponding borrowing record, and matches it with the tag information to confirm the borrowing status of the book, and check whether the book is borrowed by the current reader. The library management system, NFC tags and reader client devices perform data collaboration to obtain the reader's book return information, and perform dimensionless processing to obtain a return compliance data set, which includes the number of books returned on time nr, the total number of books borrowed js, the number of overdue days do, the number of borrowing days jt, the number of books returned without damage wh and the total number of books borrowed zs; When the library management system confirms that the book matches the borrowing record, it immediately sends confirmation information of the successful return to the reader's client device, cancels the borrowing record in the reader's account, marks the book as returned, updates the reader's borrowing history, records the return time and date, changes the book's status to available for borrowing in the library management system, and updates the book's location and quantity.

[0031] The S43 includes S431 and S432; S431. Analyze the compliance of readers' book returns based on the obtained return compliance data set, and construct a compliance formula through the library management system. When readers return books, input the obtained reader return compliance data set into the compliance formula for summary calculation to obtain the book return compliance coefficient ghg; The book return compliance coefficient ghg is calculated by the following formula; ; In the formula, e represents the exponential function, k1 represents the correction constant for adjusting the impact of overdue days on the compliance assessment of book returns, and k2 represents the correction constant for adjusting the interaction effect between overdue days and book integrity.

[0032] S432. Use the obtained book return compliance coefficient ghg to evaluate the reader's non-compliant borrowing behavior in real time and record the evaluation results. The specific evaluation plan is as follows; When the book return compliance coefficient ghg≥1, it means that the reader returns the book on time and the book is in good condition, maintains a good borrowing record, and is evaluated by S3 for credit score; When the book return compliance coefficient ghg is less than 1, it means that the reader does not return the book on time and the book is damaged, which is a non-compliant behavior. The credit score is evaluated through S3, and the reader is reminded of the borrowing violation through SMS to improve the borrowing behavior.

[0033] In this embodiment, by continuously tracking the location and status of books, the borrowing situation of books can be grasped in real time, and overdue books can be automatically reminded in time, reducing the need for manual intervention and ensuring that books are returned on time. This tracking mechanism greatly enhances the library's ability to control the borrowing process and avoids the waste of resources caused by overdue returns. Secondly, the automated verification during the return process ensures that the return information of the book accurately matches the borrowing record by scanning the book tag with an NFC card reader, avoiding errors and delays in manual verification. Through dimensionless processing, a return compliance data set is generated, and a summary calculation is performed to obtain the book return compliance coefficient ghg, effectively evaluate the reader's return compliance, and perform real-time evaluation of the reader's borrowing behavior based on the book return compliance coefficient ghg. This evaluation mechanism can not only accurately identify non-compliant borrowing behaviors, but also encourage readers to improve their borrowing habits through timely feedback, reduce overdue returns and damaged books, and effectively optimize the resource utilization efficiency of the library. This method realizes the automation and intelligent management of book borrowing and returning through the application of NFC technology, greatly improving the library's operational efficiency and service quality. The automation of the borrowing and returning process reduces the cost of manual management, and ensures the efficient use and management of book resources through real-time tracking and accurate evaluation. Compared with the traditional manual management method, it not only improves the management accuracy and transparency of the library, but also improves the experience and satisfaction of readers, ultimately bringing higher management efficiency and better service quality to the library.
