On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] like Figure 1 As shown, in at least one disclosed embodiment, a library management system is provided, including: a plurality of placement devices, an identification device and a server; the placement device displays a color combination after placing a book, and if the same book is placed in two placement devices, the two placement devices can display the same color combination; the identification device is suitable for taking images of all placement devices; the server is connected to the identification device, and the server is suitable for receiving the image taken by the identification device, and the server determines the information of the book placed in the corresponding placement device through the color combination in the image, so as to build a book database in the server; the book database is built in the server, and the required books are found through the server, and there is no need to stick labels on the bookshelf, so as to avoid the difficulty in finding books due to falling.

[0027] like Figure 2As shown, in an optional embodiment, the identification device includes: a second control module, and a plurality of shooting modules and a second communication module electrically connected to the second control module; the placement device is arranged in each layer of the bookshelf; after the books are placed, the second control module is suitable for controlling the shooting module to shoot all bookshelves to obtain images of the bookshelves; the second control module is suitable for sending the images of the bookshelves to the server through the second communication module; the shooting module can use a camera, and the camera can be arranged in the library to clearly capture the images of all bookshelves, so as to accurately identify the color combination displayed by each placement device from the image; after the staff places the books in the placement device, the staff can manually operate the placement device to make it display a color combination, which can correspond to the type of books placed in the placement device, etc., and the color combination is identified after the image is captured by the shooting module, so that the server or the second control module obtains the type of book.

[0028] In an optional embodiment, a database is provided in the server, and the database stores a unique character or character group corresponding to each color; the second control module and / or the server is configured to obtain the position corresponding to the book according to the image of the bookshelf, and obtain the color combination displayed by each placement device, match the color combination with the corresponding unique character according to the unique character corresponding to each color in the database to form a unique character group, obtain the corresponding book information from the database according to the unique character group, and construct a new book database, wherein the book database includes the type of book corresponding to each placement device, the name of the book in the placement area of ​​the placement device, and the corresponding position of the book; the corresponding position of the book is the bookshelf where the book is located, the layer number of the book on the bookshelf, and the specific placement area where the book is located on the layer number.

[0029] Each book has its corresponding unique ISBN number. Each layer of the bookshelf is provided with a placement device. The placement devices of the same bookshelf can share a key module. The placement devices are switched by the keys provided on the key module, and then the devices to be controlled in each placement device are controlled respectively, such as the light-emitting modules in each placement device. The light-emitting modules can emit light of multiple colors such as purple, yellow, green, white and red. The purple, yellow and green lights are combined in pairs to match the values ​​1-9, and the white light is used to match the number 0. The ISBN number of each book is stored in the database of the server. After placing the book on the placement device, the light-emitting modules in a placement device can be manually lit up first through the key module, so that each light-emitting module emits a color of light. Lights of different colors form a color combination, which can reflect the category of books placed in the placement device, such as industrial books, etc. The book category corresponding to each color combination is pre-stored in the database. The book category can be obtained by simply identifying the color combination in the figure. There are not many categories of books, so they can be matched by sorting combinations of a few colors.After identifying the book category, the ISBN numbers of the books in a placement device can be manually input in sequence through the key module again. The input direction can be from left to right. After a book is placed, light guide plates 4 are set on the left and right sides. When entering the ISBN number corresponding to the book, when a number is entered, the light guide plates 4 on the left and right sides of the book will emit corresponding colors. The numbers corresponding to the color combinations are shown in Table 1 below. The first row in Table 1 represents the color transmitted by the left light guide plate 4, and the first column represents the color transmitted by the right light guide plate 4. For example, at this time, when inputting the ISBN number corresponding to the leftmost book in the placement device, when 9 is entered, the corresponding light-emitting module of the light guide plate 4 on the left side of the book emits green light, and the corresponding light-emitting module of the light guide plate 4 on the right side also emits green light. At this time, image recognition can be used to determine that the number entered at this time is 9. When the corresponding light-emitting modules of the light guide plates 4 on the left and right sides of the book emit white light, it means that the number entered at this time is 0. When the corresponding light-emitting modules of the light guide plates 4 on the left and right sides of the book emit red light, , indicating that the ISBN number of the book has been input, and the color emitted next time corresponds to the ISBN number of the next book. The key module can be provided with keys with numbers 0-9 and a switch key. The switch key can make the light module emit red to indicate that the ISBN number of the current book has been input. For books in the same placement device, the ISBN number input can be judged only by the color of light emitted by the light module corresponding to the two leftmost light guide plates 4. The ISBN numbers of two books are separated by red light. Image recognition is continuously performed during the process of inputting the ISBN number of the book. The ISBN number of each placement area is obtained according to the recognized color to obtain the book name corresponding to each placement area in the placement device. The bookshelf where the book is located, the number of layers of the book on the bookshelf, and the specific placement area of ​​the number of layers where the book is located can be obtained through image recognition. The book name is associated with the corresponding position of the book and stored in a new book database to facilitate subsequent search for the book. ;
