Description

Technical Field

[0001] The present invention relates to the technical field of book management, and in particular to an intelligent book lending vehicle based on RFID and VR. Background Art

[0002] The library intelligent lending vehicle is designed to protect and improve the service quality and user experience of the library, and to realize the convenient borrowing and returning of books through intelligent and automated methods. Under the current technological background, library intelligence has become an important trend in the development of the industry, and more and more libraries have begun to introduce various intelligent equipment and technologies to improve service efficiency and user satisfaction.

[0003] At present, the development status of library intelligent technology is as follows:

[0004] Application of RFID technology: RFID technology has become one of the core technologies for intelligent library management. By attaching RFID tags to books, libraries can quickly identify, track and locate books. At the same time, RFID technology can also be combined with the self-service borrowing and returning system to realize self-service borrowing and returning of books, greatly improving the operational efficiency of the library.

[0005] Intelligent retrieval system: The intelligent retrieval system can quickly find relevant book information based on user input, including the location of the book, borrowing status, etc. This system is usually based on big data and artificial intelligence technology, and can provide users with more accurate search results and personalized recommendations.

[0006] Self-service equipment: In addition to the self-service borrowing and returning system, the library has also introduced various self-service equipment, such as self-service card processing machines, self-service printing and copying machines, etc. These devices not only improve the service efficiency of the library, but also provide users with a more convenient service experience.

[0007] Although library intelligent technology has made significant progress, there are still some technical problems in the existing solutions:

[0008] Limitations of one-dimensional barcode technology: One-dimensional barcode reading requires the scanning device to be precisely aligned with the barcode, and has strict restrictions on the scanning angle and distance. Once it is partially blocked, such as stained with dust, stains, or partially covered by other objects, it is likely to cause scanning failure. And as a static information carrier, it cannot interact deeply with VR technology.

[0009] Accuracy of intelligent retrieval systems: As far as the current situation is concerned, most intelligent retrieval systems rely mainly on manual operations in the information sorting process. Manual sorting requires a lot of time and manpower costs. When faced with a huge amount of information data, the staff are often unable to cope with it, resulting in slow progress of the entire sorting process and difficulty in meeting users' needs for quick access to accurate information.

[0010] Low intelligence: The current book sorting system is not smart enough. For example, during the book inventory process, staff still need to manually scan the barcode of each book, which is cumbersome and inefficient, and prone to omissions or repeated scanning. When returning books, the system cannot intelligently plan the optimal placement based on the real-time bookshelf space distribution and book categories, resulting in unreasonable placement of books and increased difficulty in subsequent searches. Moreover, when books are misplaced or randomly placed, the system cannot automatically identify and prompt the specific location in a timely manner. Summary of the invention

[0011] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide an intelligent book lending vehicle based on RFID and VR, which solves the problems of poor convenience of book lending and low library service efficiency in the prior art.

[0044] The sensor module 8 is installed on the side of the RFID reader;

[0045] The sensor module 8 is used to obtain sensor data, wherein the sensor data includes: surrounding environment data and obstacle position information;

[0046] The bookshelf module 2 is used to store books, the RFID reader 3 scans and reads the RFID tag information on the books, the battery compartment 6 is used to power the bookshelf module 2, the RFID reader 3, the interaction module 5, the battery compartment 6, and the drive module 7, the drive module 7 is used to realize the movement of the intelligent book lending vehicle, the control module 4 is used to match the library information according to the RFID tag information to confirm the book borrowing status, perform identity authentication on the borrowing user to obtain the verification result and generate a borrowing request according to the verification result, update the borrowing status and determine the optimal book search route according to the RFID tag information and sensor data, generate a movement instruction and send the execution movement instruction to the drive module 7, and the interaction module 5 is used to display the optimal book search route.

[0047] Specifically, 1. Chassis 1 and bookshelf module 2: The bookshelf module 2 is fixed to the chassis 1 by bolts or welding to ensure the stability and load-bearing capacity of the bookshelf. 2. RFID reader 3 and bookshelf module 2: The RFID reader 3 is installed in front of or on the side of the bookshelf module 2 by a bracket or a fixing to ensure that the RFID tag on the book can be accurately scanned. 3.

Control system: As the "brain" of the intelligent lending vehicle, it is responsible for processing various information, controlling the coordinated work of various components, and ensuring the normal operation of the entire device.

[0049] Furthermore, Figure 2 As shown, the RFID reader 3 of the smart borrowing car: the RFID reader 3 installed on the bookshelf module 2 of the smart borrowing car is used to transmit radio frequency signals and receive signals returned by RFID tags, so as to read the information in the RFID tags. The reader sends radio frequency signals of specific frequencies to the surrounding space through the antenna. When the user places the book in the scanning area of ​​the smart borrowing car, the RFID tag enters the working area of ​​the reader, and the RFID reader 3 automatically starts. The RFID tag uses the energy obtained by the induced current to send out the product information stored in the chip (passive tag), or actively sends a signal of a certain frequency (active tag). After receiving the signal, the reader decodes and processes it to obtain the information in the RFID tag. The unique identifier of the book is obtained to provide basic data for subsequent borrowing operations.

[0050] Furthermore, the control module 4 includes:

[0051] Information matching submodule, identity authentication submodule, update submodule, route generation submodule and detection submodule;

[0052] The information matching submodule is used to read the RFID tag information to obtain the book information and match the book information with the library management system for verification and determine the borrowing status of the book after the verification is passed. The identity authentication submodule is used to authenticate the identity of the borrower to obtain the verification result. The updating submodule is used to complete the borrowing operation and implement the update of the borrowing status according to the borrowing request of the borrowing user after confirming that the verification result is correct. The route generation submodule is used to determine the optimal book search route according to the RFID tag information. The detection submodule is used to determine whether the current intelligent book borrowing vehicle has a fault according to the sensor data.

[0053] Furthermore, the information matching submodule includes:

[0054] A first information acquisition unit, an information preprocessing unit, a communication unit, a status confirmation unit, and a status display unit;

[0055] The first information acquisition unit is used to read the unique identification information of the book stored in the RFID tag information to obtain the book information, the information preprocessing unit is used to check the format and integrity of the book information to obtain the preprocessed book information, the communication unit is used to match and verify with the library management system and communicate with the library management system through a local area network or a wireless network, the status confirmation unit is used to confirm the target book and the status of the current book according to the library data in the library management system and the current preprocessed book information, and the status display unit is used to display the borrowing status of the target book.

[0056] Furthermore, the control system of the intelligent lending vehicle and the library management system:

[0057] The RFID reader / writer 3 sends the read book information to the control system of the intelligent lending vehicle, and the control system then matches and verifies the information with the book information in the library management system.

[0058] The specific process of book information matching and verification between the intelligent lending vehicle control system and the library management system:

[0059] The RFID reader / writer 3 reads the book information and transmits it. The RFID reader / writer 3 equipped on the smart lending vehicle communicates with the RFID tag attached to the book through radio frequency signals, and quickly reads the book's unique identification information (such as ISBN code, collection number, etc.) stored in the tag. After successful reading, this information is sent to the control system of the smart lending vehicle in a specific data format.

[0060] The intelligent lending vehicle control system receives and pre-processes information. The control system of the intelligent lending vehicle receives book information from the RFID reader 3. First, the information is preliminarily formatted and checked for integrity to ensure that the received information is accurate and that there is no data loss or error. For example, check whether the number of data bits meets the specified ISBN code length, whether the data format is consistent with the preset encoding rules, etc.

[0061] Establish a connection with the library management system. The intelligent lending car control system establishes a communication connection with the library management system through a network (such as a local area network, wireless network, etc.). This process may involve identity authentication and authorization to ensure the security and legitimacy of the connection. For example, the intelligent lending car control system uses a pre-configured user name and password, or authenticates the library management system through a digital certificate, and a connection can only be established after verification.

[0062] Send book information for matching verification. After the connection is established successfully, the intelligent borrowing car control system will send the pre-processed book information to the library management system. After receiving the information, the library management system will perform accurate retrieval in its huge collection database based on the received book identification information.

[0063] Library management system matching verification process, information matching: the library management system searches the library's database for records that completely match the received book identification information. If no matching record is found, it means that the book may not be a book in this library, and the system will immediately return a verification failure message to the intelligent lending car control system. Borrowable status verification: If a matching record of this library's book is found, the system further checks the current status of the book. Confirm whether the book is in a borrowable state, that is, check whether the book has been borrowed, whether it is in a state that cannot be borrowed, such as being reported lost or damaged. For example, if the borrowing status field of a book is displayed as "borrowed", it means that the book is currently not available for borrowing, and the system also returns a verification failure message.

[0064] The verification result is returned. After the library management system completes the matching verification, it returns the verification result to the intelligent borrowing vehicle control system. If the book information matches and is in a borrowable state, the verification success information is returned; if the book is not a book of this library or cannot be borrowed, the corresponding failure reason is returned, such as "not a book of this library" or "the book has been borrowed".

[0065] The intelligent borrowing car control system processes the verification results. After receiving the verification results, the intelligent borrowing car control system performs corresponding processing according to different results. If the verification is successful, the VR device will display a prompt message to the staff that the book can be borrowed normally, and may be accompanied by a voice prompt to guide the staff to continue the subsequent borrowing operation; if the verification fails, the VR device will display the reason for the failure in detail to help the staff understand the situation, such as informing the staff that the book has been borrowed or does not belong to the library's collection, so that appropriate measures can be taken, such as putting the book back in place or communicating with the reader to explain the situation.

[0066] Purpose: Ensure that the scanned books are part of the library collection and are available for borrowing

[0067] Furthermore, user identity verification: user interaction interface and control system of the smart borrowing car: o The user enters personal information (such as borrowing card number, password, etc.) through the touch screen or voice recognition system of the smart borrowing car, and the control system verifies the user's identity.

[0068] Function: Ensure that the borrowing operation is initiated by a legitimate user.

[0069] Borrowing status update: Library management system: Once the user identity verification is successful and the book information matches correctly, the control system sends a borrowing request to the library management system, and the management system updates the borrowing status of the book and records the borrowing information.

[0070] Function: Complete the book borrowing operation and ensure the accuracy of the book status in the library management system. Book positioning and inventory: RFID reader 3 and book management system, RFID readers are installed on the bookshelves or specific areas in the library to monitor the location of books in real time. By regularly scanning the RFID tags of books on the bookshelves, the system can quickly determine whether the books are in the correct location, realize the book positioning function, and cooperate with the book management system to record the specific location of the books in the book management system, providing borrowers with the optimal path navigation option, so that borrowers can find the books they need.

[0071] When taking inventory of books, staff can use the RFID reader of the smart lending vehicle to move between bookshelves, quickly read book tag information, and compare it with the records in the library management system, thereby efficiently completing the book inventory work and reducing the time and errors of manual inventory. Borrowers can quickly find the required books and the optimal path to the book based on the specific location of each book recorded in the library management system.

[0072] Furthermore, the route generation submodule includes:

[0073] A second information acquisition unit and a path calculation unit;

[0074] The second information acquisition unit is used to acquire sensor data, and the path calculation unit is used to obtain the actual cost and the estimated cost according to the sensor data and book information and to obtain an evaluation function according to the actual cost and the estimated cost, so as to facilitate the evaluation function to determine the optimal book search route.

[0075] Specifically, environmental perception and data collection: sensors of smart lending vehicles (such as lidar, cameras, ultrasonic sensors, etc.);

[0076] The smart lending vehicle uses its onboard sensors to perceive the surrounding environment in real time, collect information such as the location and distance of obstacles, and provide necessary environmental data for smart navigation.

[0077] Specifically, o: A* algorithm is a heuristic search algorithm for solving path planning problems. It combines the advantages of Dijkstra algorithm (an algorithm that can find the shortest path, but the search range is wide) and greedy best-first search algorithm (exploring in the direction of the target first, but not necessarily guaranteeing the shortest path). During the search process, the A* algorithm will comprehensively consider the actual cost spent from the starting node to the current node (usually recorded as g(n)) and the estimated cost from the current node to the target node (usually recorded as h(n)), and then add these two costs to obtain the evaluation function f(n) = g(n) + h(n). The algorithm will preferentially select the node with the smallest f(n) value for expansion to find the optimal path. It guides the search of the entire library environment through the heuristic function, and can explore more quickly in the general direction of the target, avoiding wasting too much search time on some paths that are impossible to lead to the target or are obviously inefficient, greatly reducing the search space and improving the search efficiency. Provide the best route guidance for librarians to place books, so that administrators can easily go to the destination.

[0078] Ensure that the smart lending vehicle can move freely within the library while avoiding collisions with obstacles.

[0079] The control system converts the planned path and obstacle avoidance decisions into specific movement instructions, and sends them to the mobile chassis 1 and drive system of the intelligent lending vehicle to execute the movement operation.

[0086] Step description: The control system generates a personalized book recommendation list based on the user's historical borrowing records and preferences using a recommendation algorithm, and displays it to the user through a user interaction interface.

[0087] Function: Improve user experience and meet users' personalized reading needs.

[0088] Borrowing record query

[0089] Execution entity: Digital human + VR interactive interface and library management system of smart lending vehicle

[0090] Step description: AI digital human technology is an intelligent device based on a large model. It interacts with readers through natural language processing and image recognition capabilities. It has powerful information retrieval capabilities and can quickly obtain relevant information such as the library's opening hours, floor distribution, and the location of the collection's books. VR panoramic technology uses real-life modeling to fully replicate the library's real-life space, bringing readers a new digital space experience, supporting 3D bird's-eye view of each floor layout, and providing an electronic sandbox function to achieve an immersive navigation experience. Combining the voice interaction of AI digital human technology and the VR navigation function of VR panoramic technology, a three-dimensional space navigation solution is provided for library administrators, including the shortest route guidance and arrow markings for sorting books. Administrators can switch navigation functions independently, such as switching perspectives, zooming in and out, etc. VR real-life navigation can accurately locate the administrator's location and provide detailed navigation guidance to the destination, allowing administrators to easily reach the bookshelf where the books are placed.

[0091] It is convenient for administrators to see the location and placement of bookshelves at a glance, speeding up the efficiency of organizing books.

[0092] Intelligent maintenance and fault detection methods

[0093] Real-time monitoring and data collection

[0094] Execution entity: Sensors and control systems of smart lending vehicles

[0095] Step description: The sensors of the smart lending vehicle monitor the vehicle's operating status (such as battery power, motor temperature, sensor status, etc.) in real time and send the data to the control system.

[0096] Function: Provide real-time data support for fault detection.

[0097] Fault prediction and diagnosis

[0098] Execution entity: Control system and fault prediction algorithm of intelligent lending vehicle

[0099] Step description: The control system uses a fault prediction algorithm to analyze the real-time monitored data, predict potential fault points, and generate a fault diagnosis report.

[0100] Function: Discover potential faults in advance to avoid the impact of faults on borrowing services.

[0101] Maintenance reminders and remote repairs

[0102] Executing entity: Control system and remote maintenance platform of intelligent lending vehicle

[0103] Step description: Once the control system detects a fault or predicts a potential fault, it will remind the user or library manager to perform maintenance through the digital human + VR interactive interface. For some faults that can be repaired through remote operation, the control system will try to repair them through the remote maintenance platform.

[0104] Function: Ensure the long-term stable operation of smart lending vehicles and reduce service interruptions caused by failures.

[0105] More specifically, the working principle and specific process of borrowing a car are as follows:

[0106] 1. Data reception and integration: The control system of the smart loan vehicle receives data transmitted from sensors that monitor the vehicle's operating status in real time. These data cover multiple key aspects such as battery power, motor temperature, and sensor status. The control system integrates these different types of data to form a data set that fully reflects the vehicle's operating status, providing a basis for subsequent analysis.

[0107] 2. Algorithm selection and loading: The control system uses the deep learning long short-term memory network (LSTM) algorithm based on the vehicle's operating characteristics and historical fault data. LSTM is a special recurrent neural network that is good at processing time series data and can capture long-term dependencies in the data. The operating status data of the smart loan vehicle has time series characteristics. LSTM can learn the data of each component of the vehicle that changes over time and predict potential faults. The control system loads it into the data analysis module and prepares to analyze the integrated data.

[0108] 3. Data feature extraction: The algorithm performs feature extraction on the integrated data set. It will filter out key features related to potential faults from a large amount of data, such as the changing trend of battery power, the abnormal fluctuation frequency of motor temperature, etc. These features can more accurately reflect the relationship between the vehicle's operating status and potential faults.

[0109] 4. Model training and analysis: The algorithm trains the model based on the extracted feature data, comparing and analyzing the current vehicle operation data with the historical fault data. During the training process, the algorithm continuously adjusts the model parameters to improve the accuracy of predicting potential faults. Through this comparison, the algorithm is able to identify patterns and trends in the data that may indicate potential faults.

[0110] Fault prediction and report generation: After analysis, the algorithm determines whether there are potential fault points in the vehicle. If a potential fault is predicted, the control system will generate a detailed fault diagnosis report. The report includes information such as the location of the potential fault, possible fault type, probability of fault occurrence, and possible impact on vehicle operation. This report provides an important basis for subsequent maintenance work, helping staff to formulate maintenance plans in advance and take corresponding measures to avoid the impact of faults on borrowing services.
