Description

Technical Field

[0001] This invention relates to the field of intelligent book management technology, specifically to an intelligent bookshelf device, system, and control method based on a carrier communication camera. Background Technology

[0002] The core function of a library is the collection, organization, preservation, and transmission of documentary resources, as well as providing readers with services such as inquiry and borrowing. In the daily operation of a library, a large number of bookshelves are typically deployed to achieve centralized storage and classified management of the collection. With the advancement of library informatization and intelligentization, machine vision-based intelligent management solutions are gradually being applied to scenarios such as collection management, book inventory, shelving inspection, and security assistance. To achieve real-time perception of the status of books on shelves, existing technologies often involve deploying surveillance cameras within the library to capture images of the bookshelf area. These cameras are usually fixed in place, such as by installing rails or cantilever structures on walls, ceilings, or bookshelves. Some solutions also utilize mobile robots carrying cameras that move between bookshelves to achieve image capture and coverage of the bookshelf area.

[0003] However, the aforementioned methods of fixed camera deployment or mobile robot acquisition are often highly dependent on the library's environment. For example, they require specific conditions regarding floor flatness, bookshelf spacing, ceiling height, and spatial layout. In practice, these methods are prone to issues such as obstructed views, blind spots, or incomplete data acquisition, making it difficult to achieve comprehensive and stable image acquisition of the library's collection. Furthermore, large-scale camera deployments often involve complex network cabling and construction modifications, resulting in high initial construction costs. Subsequent expansion and redeployment are necessary as the collection grows or bookshelves are adjusted, leading to a heavy workload and insufficient flexibility in operation and maintenance. Therefore, existing technologies still have shortcomings in terms of coverage completeness, deployment convenience, initial construction costs, and flexibility in subsequent expansion and maintenance of library images, requiring further improvement. Summary of the Invention

[0004] To address the aforementioned deficiencies in existing technologies, this invention provides an intelligent bookshelf device, system, and control method based on a carrier communication camera. By integrating a quick-connect camera module into the front end of the bookshelf top panel and utilizing the mains power supply line for power supply and data transmission, stable acquisition of images of books on the shelves is achieved, reducing deployment and maintenance costs.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A smart bookshelf device based on a carrier communication camera includes a smart bookshelf and a quick-connect camera module; The smart bookshelf includes a bookshelf body and power supply lines arranged in the bookshelf body. The bookshelf body has a multi-layer structure, with the front end of the top plate of each layer extending forward relative to the book placement area of ​​each layer to form an installation area for installing the quick-connect camera module. The installation area is provided with a fixing part for positioning and installing the quick-connect camera module, the fixing part including quick-connect terminals and fixing structure; The quick-connect camera module includes a housing and an ultra-wide-angle camera, a control module, a carrier communication module, and quick-connect terminals disposed within the housing. The ultra-wide-angle camera faces the direction of the books on the current layer and is used to collect image data of the books on that layer. The quick-connect camera module is electrically connected to the power supply line through the quick-connect terminal to provide power to the quick-connect camera module, and data is transmitted through the power supply line via the carrier communication module.

[0006] Preferably, the quick-connect terminal is a pluggable connector to enable hot-swap installation and replacement of the quick-connect camera module; the fixing structure adopts at least one of the following: slot structure, slide rail structure, and magnetic structure, for fixing, disassembling, and adjusting the position of the quick-connect camera module.

[0007] Preferably, the fixing structure is a slide rail structure, and the housing of the quick-connect camera module is provided with a guide groove that cooperates with the slide rail structure.

[0008] Preferably, the ultra-wide-angle camera has a field of view of 120° or greater to achieve coverage and capture of books on a single bookshelf.

[0009] Preferably, the power supply line in the bookshelf body is a pre-fabricated line inside the bookshelf body or a line added to the bookshelf body. The power supply line is connected to a universal socket to draw power for supplying power to the quick-connect camera module.

[0010] On the other hand, this invention discloses a library smart bookshelf system based on a carrier communication camera, comprising: Multiple of the aforementioned smart bookshelf devices, power supply lines, and at least one control gateway; The power supply line is the mains power supply line in the library, and the intelligent bookshelf device obtains power through the power supply line. The control gateway includes a carrier communication module and a network communication module. The carrier communication module communicates with the carrier communication module in the smart bookshelf device through the power supply line to realize the control of the quick-connect camera module and the transmission of image data. The network communication module is used to upload the image data to a data center or Internet platform.

[0011] Preferably, the control gateway is used to link with the library management system to control the quick-access camera module of the corresponding bookshelf layer to perform real-time image acquisition when a book borrowing behavior occurs; the control gateway is used to perform regional polling control on multiple smart bookshelf devices during system idle time or according to a preset cycle, so as to control the corresponding quick-access camera module to acquire images of books on the shelf for book inventory or shelf arrangement inspection.

[0012] Preferably, the control gateway is used to control the quick-connect camera module to switch between active and dormant states, and to adjust the image or video acquisition cycle of the quick-connect camera module; the control gateway is used to perform bandwidth management control on multiple quick-connect camera modules to avoid multiple quick-connect camera modules from simultaneously performing image acquisition and data transmission.

[0013] Preferably, the control gateway is communicatively connected to several IoT sensors deployed in the library. The control gateway is used to link the sensing data of the IoT sensors with the image data collected by the quick-connect camera module to achieve personnel trajectory tracking, reader profiling, fire safety monitoring, or intelligent management of the venue.

[0014] Furthermore, this invention also discloses a control method for a library intelligent bookshelf system based on a carrier communication camera, applicable to the aforementioned library intelligent bookshelf system based on a carrier communication camera. The control method includes the following steps: S1, the control gateway sends control commands to the quick-connect camera module through the power supply line to control the quick-connect camera module to enter the active state and collect book image data; S2, the quick-connect camera module transmits the acquired image data back to the control gateway via the power supply line; S3 controls the gateway to aggregate and process image data, and uploads the image data to the Internet or data center or receives information from the Internet or data center through the network communication module, thereby realizing the management and control of the library's intelligent bookshelf system. Compared with the prior art, the advantages of the present invention are as follows: (1) By placing the quick-connect camera module at the front end of the top plate of each layer of the smart bookshelf and using the mains power supply line to realize power supply and carrier communication data transmission, the camera deployment and image acquisition system can be quickly completed in the library, which significantly simplifies the integrated wiring project of strong and weak current. The system operation does not rely on the wireless network, avoiding the problem of unstable acquisition due to signal quality or insufficient network coverage. At the same time, the camera is installed on the bookshelf itself, without the need for construction and modification on the wall, ceiling or floor, reducing the dependence on the building structure, space conditions and decoration environment of the venue, which helps to reduce obstruction and coverage blind spots, and improve the integrity and adaptability of image acquisition of books on the shelf.

[0015] (2) This invention supports customized bookshelves with pre-embedded cables and fixing devices, and can also modify existing bookshelves. Combined with a modular quick-connect structure, it enables quick disassembly and assembly, hot-swappable replacement and on-demand deployment of cameras, so that the investment in system construction increases linearly with the scale of the book collection, and can achieve smooth expansion and upgrade as the book collection increases. Furthermore, since this invention uses a modular plug-in method to achieve image acquisition, compared with the solution that relies on mobile robots, robotic arms or complex sliding rail mechanisms, it reduces moving mechanical parts, reduces the failure rate, simplifies the operation and maintenance management process, and facilitates the rapid replacement of faulty equipment, thereby effectively reducing subsequent operation and maintenance costs and saving manpower investment.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the present invention.

[0019] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0020] like Figure 1-4 As shown, this embodiment discloses an intelligent bookshelf device based on a carrier communication camera, including an intelligent bookshelf 1 and a quick-connect camera module 2. The intelligent bookshelf 1 serves as the basic carrier for carrying books and deploying cameras, and is used to complete the installation of cameras and power supply on the bookshelf. The quick-connect camera module 2 serves as an image acquisition unit, and is used to acquire images of the books on the shelf and interact with data from an external control gateway.

[0021] The intelligent bookshelf 1 includes a bookshelf body and power supply lines arranged within the bookshelf body. The bookshelf body has a multi-layer structure, with the front end of the top plate 3 of each layer extending forward relative to the book placement area of ​​each layer, forming an installation area for mounting the quick-connect camera module 2. The installation area formed by the extension of the front end of the top plate 3 provides installation space for the quick-connect camera module 2 and allows the camera to face the books inside the bookshelf for shooting. The installation area is provided with a fixing part 4 for positioning and installing the quick-connect camera module 2. The fixing part 4 includes a quick-connect terminal 5 and a fixing structure 6. The quick-connect terminal 5 is used to realize the electrical connection between the quick-connect camera module 2 and the power supply lines, and the fixing structure 6 is used to realize the positioning and installation of the quick-connect camera module 2 within the installation area. The fixing structure 6 adopts at least one of the following: a slot structure, a slide rail structure, and a magnetic structure, for fixing, disassembling, and adjusting the position of the quick-connect camera module 2. Preferably, the fixing structure 6 is a slide rail structure. The housing of the quick-connect camera module 2 is provided with a guide groove that cooperates with the slide rail structure. The guide groove and the slide rail structure can limit the movement direction of the quick-connect camera module 2 and improve the stability of the installation process. At the same time, it is convenient for the quick-connect camera module 2 to be positioned in the installation area at the front end of the top plate 3, so that the camera can obtain a more suitable shooting angle and coverage.

[0022] The quick-connect camera module 2 includes a housing and an ultra-wide-angle camera, a control module, a carrier communication module, and quick-connect terminals 5 disposed within the housing. The ultra-wide-angle camera faces the direction of the books on the current shelf and is used to collect image data of the books on that shelf. Preferably, the ultra-wide-angle camera has a field of view greater than or equal to 120° to achieve coverage acquisition of books on a single shelf. The control module is used to control the working state of the quick-connect camera module 2, and the carrier communication module is used for data transmission based on the power supply line. The quick-connect camera module 2 is electrically connected to the power supply line through the quick-connect terminals 5 to provide power to the quick-connect camera module 2, and data transmission is carried out through the power supply line via the carrier communication module, thereby completing the acquisition and transmission of book images without laying additional network cables.

[0023] The quick-connect terminal 5 is a pluggable and dockable structure, including a bookshelf-side terminal located in the installation area of ​​the smart bookshelf and a module-side terminal located on the quick-connect camera module. The two are electrically connected through plugging and unplugging, thus enabling power supply to the quick-connect camera module and supporting hot-swapping installation and replacement. Furthermore, the power supply line within the bookshelf body is either pre-installed inside the bookshelf or added to the bookshelf body. This power supply line connects to a universal socket to supply power to the quick-connect camera module 2. This pre-installed or added method is compatible with both new bookshelf construction and existing bookshelf renovation applications, allowing the smart bookshelf 1 to provide stable power to the quick-connect camera module 2 when only connected to mains power. It also works with the carrier communication module to achieve a unified link for power supply and data transmission.

[0024] like Figure 5-6As shown, another embodiment of the present invention discloses a library intelligent bookshelf system based on a carrier communication camera, comprising: multiple intelligent bookshelf devices, a power supply line, and at least one control gateway. The multiple intelligent bookshelf devices can be deployed in the library according to bookshelf areas. Each intelligent bookshelf device can function as an independent image acquisition unit to acquire images of books on the shelves. The control gateway serves as the centralized management and data aggregation node of the system, used for unified control of the multiple intelligent bookshelf devices and receiving transmitted data. The power supply line is the mains power supply line within the library. The intelligent bookshelf devices obtain power through the power supply line, providing a power supply foundation for the quick-connect camera module 2, thereby completing the system power supply deployment without laying additional dedicated power cables. The control gateway includes a carrier communication module and a network communication module. The carrier communication module communicates with the carrier communication module in the intelligent bookshelf device through a power supply line to control the quick-connect camera module 2 and transmit image data. The carrier communication method can utilize existing power lines to complete the issuance of control commands and the transmission of image data, reducing network cabling workload and improving the system's adaptability in complex venue environments. The network communication module is used to upload image data to a data center or Internet platform. The network communication module can further forward the image data collected by the control gateway to external platforms for storage, analysis, or business processing, thereby providing data support for intelligent library management applications such as book inventory, shelving inspection, and security assistance.

[0025] In this embodiment, the power supply line includes two parts: the power supply line in the bookshelf body and the mains power supply line in the library venue. The power supply line in the bookshelf body is used to introduce and distribute the mains power to the installation areas on each floor. The mains power supply line in the library venue is the existing building power pipeline of the venue. After the two are electrically connected, they together form a power supply and carrier communication link.

[0026] Furthermore, the control gateway can be used to link with the library management system. When a book borrowing occurs, it controls the quick-access camera module 2 of the corresponding bookshelf layer to perform real-time image acquisition. Through data interaction with the library management system, it can obtain borrowing event information or trigger signals, enabling the control gateway to quickly locate the corresponding bookshelf layer and schedule the quick-access camera module 2 of that layer to perform image acquisition when a borrowing occurs. This achieves timely recording of the status of books on the shelves and business linkage. The control gateway is also used to perform regional polling control of multiple smart bookshelf devices during system idle time or according to a preset cycle, so as to control the corresponding quick-access camera module 2 to acquire images of books on the shelves for book inventory or shelving checks. Through regional polling, periodic image acquisition of the library's collection can be completed without affecting the normal operation of the library, forming an image data foundation that can be used for inventory, shelving verification, or anomaly identification.

[0027] In this embodiment, the control gateway can be used to control the quick-connect camera module 2 to switch between active and sleep states, and to adjust the image or video acquisition cycle of the quick-connect camera module 2. By controlling the switching between active and sleep states, the working time of the camera can be reduced during periods when continuous high-frequency acquisition is not required, thereby reducing energy consumption and extending the service life of the device. At the same time, by adjusting the acquisition cycle, the acquisition strategy can be flexibly set according to the usage frequency or management needs of bookshelves in different areas. The control gateway is also used to perform bandwidth management control on multiple quick-connect camera modules 2, avoiding multiple quick-connect camera modules 2 from simultaneously performing image acquisition and data transmission. By staggered scheduling or batch transmission, the instantaneous data pressure of power line carrier communication can be reduced, transmission congestion can be reduced, and the stability of image data transmission can be improved.

[0028] In some embodiments, the control gateway communicates with several IoT sensors deployed in the library. The control gateway is used to link the sensor data from the IoT sensors with the image data collected by the quick-connect camera module 2 to achieve personnel trajectory tracking, reader profiling, fire safety monitoring, or intelligent venue management. For example, it can incorporate data from environmental monitoring, access control, smoke, infrared, and positioning sensors with the image acquisition results for correlation analysis, enabling the system to further expand beyond book image acquisition to smart venue application scenarios such as personnel behavior analysis, risk warning, and comprehensive management. Furthermore, the library's intelligent bookshelf system has an anomaly detection function, which can serve as a supplement to security monitoring. By scheduling the quick-connect camera module 2 through the control gateway to acquire images of the book-on-shelf area of ​​the intelligent bookshelf 1, it can obtain image information of the corresponding area when an abnormal event occurs. This information can be used for fire hazard identification, recording of abnormal personnel behavior, or collection of rodent signs, thereby providing auxiliary data support for library security management.

[0029] like Figure 7 As shown, another embodiment of the present invention also discloses a control method for a library intelligent bookshelf system based on a carrier communication camera, applied to the aforementioned library intelligent bookshelf system based on a carrier communication camera. The control method includes the following steps: S1, the control gateway sends a control command to the quick-connect camera module 2 through the power supply line to control the quick-connect camera module 2 to enter the activation state and collect book image data; in this step, the control command can be used to trigger the quick-connect camera module 2 corresponding to the specified layer of the specified smart bookshelf 1 to start image acquisition, so that the quick-connect camera module 2 enters the working state and outputs book image data when it is needed, thereby avoiding redundant data and increased energy consumption caused by long-term continuous acquisition; S2, the quick-connect camera module 2 transmits the acquired image data back to the control gateway through the power supply line; in this step, the image data is transmitted in the power supply line based on carrier communication and transmitted back to the control gateway, realizing data interaction between the image acquisition end and the control end, so that the control gateway can receive and aggregate image data from different smart bookshelves 1 and different layers; S3, the control gateway aggregates and processes image data, and uploads the image data to the Internet or data center or receives information from the Internet or data center through the network communication module, thereby realizing the management and control of the library's intelligent bookshelf system. In this step, the aggregation and processing may include operations such as image data collection, caching, identification association and basic analysis. The network communication module is used to further transmit image data or processing results to an external platform for storage, recognition or business processing, or to receive processing results and management strategies returned by an external platform, thereby completing the unified scheduling and operation management of the library's intelligent bookshelf system.

[0030] It should be noted that in recent years, technologies such as ultra-wide-angle cameras and power line carrier communication have matured, and the modularity and miniaturization of related equipment have continuously improved while manufacturing costs have continued to decrease. This has made it possible to adopt a larger number of denser image acquisition methods in library settings. Compared to traditional solutions that typically deploy only a few cameras in an area and rely on long-distance shooting for coverage, resulting in inaccurate book image acquisition and susceptibility to obstruction, this invention uses quick-connect camera modules 2 arranged close to the smart bookshelf 1 to achieve close-range, directional acquisition of books on the shelves. This significantly improves the clarity and coverage of the acquired images. Simultaneously, combined with the power line carrier communication transmission method, it reduces network cabling workload and facilitates rapid addition of cameras or replacement of faulty modules, thus better adapting to the actual needs of library collection changes and intelligent management. The deployment of cameras can be flexibly adjusted according to the number of books and the size of the bookshelves. Cameras can be installed only on bookshelves with books, while those on empty bookshelves can be temporarily left uninstalled, achieving full coverage of books and avoiding camera idleness.

[0031] In summary, this invention discloses an intelligent bookshelf device, system, and control method based on a carrier communication camera. By installing quick-connect camera modules 2 at the front end of the top plate 3 of each layer of the intelligent bookshelf 1, and connecting them to the internal power supply lines using quick-connect terminals 5, image data transmission is completed via the power supply lines using the carrier communication module built into the quick-connect camera modules 2. The data is then uniformly controlled and aggregated by a control gateway, thus constructing a rapidly deployable intelligent bookshelf system for libraries. This technical solution enables the nearby deployment and stable acquisition of cameras without damaging the original building structure and decoration of the library, reducing the workload of integrated power and low-voltage wiring, supporting the rapid installation, replacement, and maintenance of the quick-connect camera modules 2, and facilitating on-demand expansion and upgrades, thereby reducing system failure rates and subsequent maintenance costs. Through the implementation of this invention, the coverage integrity and management efficiency of image acquisition of books on library shelves can be effectively improved, providing reliable data support for rapid book inventory, shelving inspection, and smart security, demonstrating significant promotional value and industry application significance.

For the sake of brevity, they are not provided in detail. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
