New description: [New technical field] This creation has an identification system, especially about the intelligent bookcase recognition system. [Prior Art] Radio Frequency Identification (RFID) technology uses an RFID reader with an antenna to generate an electromagnetic field or emit electromagnetic waves to a radio frequency identification tag (RFIDtag). The radio frequency identification tag receives electromagnetic waves or senses The electromagnetic field or electromagnetic wave that can be generated after the electromagnetic field is recognized by the RFID reader. The method of wireless identification through RF identification technology has been widely used for automated production noise, storage management, electronic charging and other purposes. On the other hand, bookcases are equipment used in libraries or individual study rooms to store large amounts of vouchers. When the user's collection increases, the management of the book is also more important. Traditionally, the technique of shooting is based on the book pivot. Each book can be placed with a radio frequency identification tag to identify the RFID reader in the bookcase for book management purposes. ...,: The RFID reader may not be able to read all the books or cough up books that are not placed on the bookcase. For example, when the book in the bookcase is continuously discharged in the bookcase in two or thirty, the density of the two sheets of the book is high and may contain part of the moisture due to the change of moisture in the air. It is difficult for electromagnetic waves or electromagnetic fields to penetrate books, resulting in a decrease in the recognition rate. For another example, because of the electromagnetic field (or electromagnetic wave) reflection caused by the environment, the RFID reader in the bookcase may also read the RFID tag of the book that is not placed on the bookcase. Therefore, the use of radio frequency identification M439861 technology to design a bookcase that is easy to manage books is the goal of research and development in this field. [New Content] The present invention provides a smart bookcase identification system for recognizing books placed in a bookcase, and the books in each bookcase unit are respectively identified by a radio frequency identification reader in the bookcase unit. . The smart bookcase recognition system provides a good book recognition rate. The present creative embodiment provides an intelligent bookcase identification system comprising at least two bookcase units and at least one isolation structure. The bookcase units are arranged adjacent to each other, and each bookcase unit is used to place a plurality of books. Each book has a radio frequency identification tag. Each bookcase unit includes a first RFID reader. The first RFID reader has an antenna. The first RFID reader is placed on the first side of the bookcase unit for reading the RFID tags of the plurality of books placed in the bookcase unit. Each isolation structure is disposed between two adjacent bookcase units, the isolation structure has at least three metal plates, and the metal plates are stacked in a three-layer structure, and the length of one side of each metal plate is greater than the operating frequency of the antenna. One-half wavelength. The books in the bookcase unit are arranged in the side direction. In summary, the smart bookcase identification system provided by the present embodiment is for identifying a book placed in a bookcase, and each book in the bookcase unit is read by radio frequency identification in the bookcase unit. To identify. The smart bookcase recognition system provides a good book recognition rate. In order to further understand the characteristics and technical content of this creation, please refer to the detailed description and drawings of 4/12, but these instructions and the cups are used to clarify the creation, not the right to this creation. [Function] u F [Embodiment] [Embodiment of the intelligent bookcase identification system] The system is only 1 in the figure 1 Figure 1 is the smart bookcase identification = 7^, figure ° smart bookcase identification of the creation example The system 1 comprises at least two books = 70 1, 1 and at least one isolation structure] 2. Each bookcase unit 11 includes a first-Lylang read H (1). To help (4), in the figure! = two bookcases % u and _ an isolation structure 12 is taken as an example, but in this creation = therefore limited. The bookcase units U can be arranged adjacent to each other, as shown in Figure 1 = from top to bottom as an example 'but this creation is not limited, when narrow = In the implementation, according to the design requirements of the smart bookcase, the book can be arranged from left to right (or from right to left). The system 1 can have a plurality of weaving units η and plural; =, the bookcase unit η Arranged from top to bottom, each bookcase unit is used to place a plurality of books 2. Each 蚩 2 1 # π The mother-in-law 2 has a radio frequency identification (not shown). Each-book #unit u includes the first-radio frequency identification read. The younger one radio frequency identification reader] is placed in the (four) unit]] 】The right side of the side shown. Each of the isolation structures I] is placed between two phased bookcase units. In this embodiment, each of the bookcase units 1 can have a full frame and The book cabinet unit U arranged in the bottom can also be integrated into a 5/12 M439861 type structure to form the body of the book cabinet. For example, when the body of the book cabinet or the bookcase unit 11 has a metal frame, or when the body of the book cabinet or the bookcase unit 11 is metal When manufactured, the bookcase unit 1 and the bookcase body can reduce the electromagnetic wave generated by the first RFID reader 111 and the RFID tag of the book from being reflected outside the book cabinet body, thereby reducing the error rate of recognition. When the body or bookcase unit 11 of the bookcase has a metal frame, or when the body of the book or the bookcase unit 11 is made of metal, the electromagnetic field (or electromagnetic wave) outside the bookcase is caused by the first RFID reader 111 of The interference can also be reduced. Please refer to FIG. 1 and FIG. 2 simultaneously, which is a schematic diagram of the main radiation beam of the antenna of the first RFID reader of the present embodiment. The first RFID reader 11 has an antenna. (not shown) for reading the radio frequency identification tag of the plurality of books 2 placed in the bookcase unit 11. The first radio frequency identification reader 11 further includes a radio frequency circuit and a control circuit (for example, a microcontroller (Micro Controller) Unit, MCU)), etc., those skilled in the art should be able to easily understand the implementation of the RF circuit and control circuit of the RFID reader, and will not be described again. In addition, each book 2 has a radio frequency identification tag which usually has Dipole antennas and related circuits are not described here. The antenna of the first RFID reader 111 may be an array antenna. The angle 0 shown in Fig. 2 is the angle between the direction in which the strongest beam of the main radiation beam of the antenna is halved and the direction in which the intensity of the main radiation beam is halved. The half-power width 20 (i.e., 3 dB Beamwidth) of the main radiation beam of the antenna of the first RFID reader 111 may be preferably between 40 and 50 degrees, but the present creation is not limited thereto. In addition, the maximum gain value of the antenna of the first RFID reader 111 may be at least 9 dBi. Please refer to FIG. 3. FIG. 3 is a schematic diagram of a 6/12 M439861 of the isolation structure of the present embodiment. Since the mother-isolation structure 12 is placed between two adjacent bookcase units η, the number of isolation structures 12 is the number of bookcase units u minus! . The isolation structure 12 has at least three metal plates 121 which are stacked in a two-layer structure as shown in FIG. According to the principle of the parallel plate waveguide, the isolation structure 12 allows the electromagnetic waves propagating to the isolation structure 12 to be suppressed without being easily radiated. The electromagnetic waves in the isolation structure 12 can be propagated in a Transverse Magnetic (TM) or Transverse Electric (TE) mode. In other words, the isolation structure 2 can block electromagnetic waves from being transmitted between adjacent bookcase units 11. In addition, the distance between the metal plates 121 can be designed according to requirements, and the present invention does not limit the distance between the metal plates 121. In other words, when the metal plates 121 are stacked into the isolation structure 12, the thickness of the isolation structure 12 can also be adjusted according to actual needs. Referring to Figure 3, the length of one side of each of the metal plates 12i (i.e., the side of the χ axial direction) is greater than one-half the wavelength of the operating frequency of the antenna of the first RFID reader u. For example: When the antenna is operated at 9 〇〇 MHz, the length of the side of the X-axis of the metal plate 12 may be greater than about 167 mm. The book 2 in the bookcase unit u is along the side X axis) arranged and placed. . . Referring to the drawings and FIG. 4A, FIG. 4A is a schematic diagram of the housing portion of the book cabinet of the present embodiment. The smart bookcase identification system 4 is substantially the same as the smart bookcase identification system, and the only difference is that each of the bookcase units 41 of the knowledgeable bookcase 4 has a plurality of portions 412. The accommodating portion 4 2 is for accommodating books, and the accommodating portion 412 is arranged along the side of the metal plate=X axial direction (that is, the accommodating portion 4 is arranged along the χ axis direction) 2 may be adapted to accommodate books The outer frame, in other words, the 7/12 M439861 accommodating portion 412 has an accommodating space for accommodating the book. The accommodating portion 412 allows the user to put the book in accordance with the position of the accommodating portion 412. The recognition rate can be effectively improved. The accommodating portion 412 can be made of a non-conductive material to allow the electromagnetic field generated by the first RFID reader 411 and the RFID tag of the book to easily pass through. Referring to FIG. 4A, The two adjacent accommodating portions 412 have a predetermined spacing d, and the space formed by the predetermined spacing d can avoid the problem that the electromagnetic waves generated by the continuous arrangement of the books are not easily penetrated, thereby preventing the recognition rate of the books from decreasing. When the operating frequency of the antenna of the first RFID reader 411 is 900 MHz, the predetermined pitch d may be 2 cm to 5 cm, but the present creation is not limited thereto. In other words, the reservation of the adjacent housing portion 412 is not limited. The space within the spacing d is not pendulum The book can be placed in such a way that the recognition rate of the book can be improved. It is worth mentioning that the accommodating portion 412 in Fig. 4A is only for help, and the number of the accommodating portions 412 is adjustable according to the actual size of the book cabinet body. Please refer to FIG. 4A and FIG. 4B and FIG. 4B , which are schematic diagrams of the accommodating portion and the spacing portion of the book cabinet unit of the present embodiment. The smart bookcase identification system 4 ′ is substantially the same as the smart book cabinet recognition system 4 , and the difference is only Each of the bookcase units 411 of the smart bookcase identification system 4' has a plurality of spacers 413, and the spacers 413 are disposed between two adjacent receiving portions 412. The spacers 413 may be made of an electromagnetic field. (or electromagnetic wave) penetrating material, for example: non-conductive plastic, styrofoam, wood, etc. The partition 413 may also be a hollow casing, and the hollow portion of the casing only has air, so that the electromagnetic wave propagates. It is not easy to be affected. It is worth mentioning that the shape of the spacer 413 in Fig. 4B is not limited to 8/12 412M439861, as long as the spacer 4 is placed adjacent to the benefit date. The space within the pre-twisting distance d of the accommodating portion may be used. [Another embodiment of the smart bookcase identification system]
