[0001] The present invention belongs to the technical field of smart bookshelves, and in particular relates to a multifunctional smart bookshelf. Background Art

[0002] With the widespread adoption of RFID (Radio Frequency Identification) technology in libraries, smart bookshelves have become standard equipment in many large and medium-sized libraries. Smart bookshelves enable real-time location, inventory, and search of books on shelves, making it easier for readers to find books, reducing the workload of librarians, and improving the library's technological advancement and user satisfaction.

[0003] Existing bookshelves are provided with multiple groups of support plates from top to bottom, and the storage height above each layer of support plates is different, so books of different heights are placed on different support plates; however, in most cases, after readers take out a book, if they are not going to take it away, they will simply put it in a grid of the bookshelf when putting it back, without considering or being able to know whether the book is on the corresponding layer of support plates. Summary of the Invention

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the present invention is a multifunctional intelligent bookshelf, whose frame is composed of a bottom frame 1, a top frame 12 and vertical beams 11 on both sides; each layer of the supporting structure is composed of two supporting longitudinal beams 2 and a supporting cross beam 13, and a book carrying plate 21 is laid on the supporting longitudinal beams 2.

[0028] At the same time, a groove is opened on the surface of the supporting crossbeam 13 and a pressure sensor of model FSR402 is installed. The top of the pressure sensor is covered with a rubber elastic block. The positioning blocks 15 set at both ends of the supporting longitudinal beam 2 are inserted into the groove so that the bottom surface of the positioning blocks contacts the rubber elastic block, completing the construction of the mechanical conduction path.

[0029] Install the installation assembly 3 between the two vertical beams 11 on both sides of each layer of the support structure; Figure 5-6 As shown, the mounting assembly 3 is an I-shaped slot plate 30, with a "["-shaped cover plate A31 and a "["-shaped cover plate B32 respectively engaged on both sides of the slot plate 30; and a plurality of mounting holes A301 for mounting infrared distance sensors A are provided along the length direction of the slot plate 30. When in use, an infrared distance sensor A model E3F-DS30P1 is fixed in the mounting hole A301 of the slot plate 30 above each layer of the supporting structure, and the transmitting end of the infrared distance sensor A is aligned with the transparent window 311 provided on the "["-shaped cover plate A31;

[0030] A linear module of model XYL-4010 is installed just above each layer of book carrying plate 21, and the slider of the linear module is equipped with an infrared distance sensor B of model E3F-DS30P1;

[0031] The infrared distance sensor model E3F-DS30P1 has a measurement accuracy of ±1mm.

[0032] Based on the above, in order to detect whether the books are placed on the corresponding layer of support structure after being placed, and to broadcast the detection results, a controller with model STM32F407 is also provided, and the controller is connected to the pressure sensor, infrared distance sensor A, and infrared distance sensor B; and the controller is also connected to the alarm module and the strip light strip arranged on the frame above the corresponding layer of support structure through the RS485 bus; and the alarm module includes a speaker and an LED warning light.

[0033] Based on the above settings, when using

[0034] The pressure sensor monitors the load changes of the supporting longitudinal beam 2 in real time and triggers the positioning process when it detects an increase in the weight of a certain layer;

[0035] The infrared distance sensors A on both sides of the layer are activated synchronously to determine the horizontal position coordinates of the books;

[0036] The controller starts the linear module, drives the infrared distance sensor B to move to the horizontal position coordinate, and detects the height of the book;

[0037] The scanned book height data is compared with the preset floor height threshold: if the detected book height exceeds the design tolerance of the floor, for example, if the floor height is 200mm and the detected book height is 220mm, the speaker is triggered and the LED warning light of the floor is lit to indicate misalignment;

[0038] At the same time, in the above, when the pressure sensor detects that the weight of a certain layer increases, the light strip is controlled to light up for illumination, which not only makes it convenient to return books in a dim environment, but also makes it convenient for users to observe books during the borrowing process.

[0039] It can be known that in the wiring harness space formed between the slot plate 30 and the cover plate B32, a wiring harness fixing member is provided on the bottom side of the slot plate 30, such as Figure 6-7 The wiring harness fixing part includes a base plate 33, on which a wiring harness fixing pressure plate 334 is provided to form a gap with the base plate 33; one end of the wiring harness fixing pressure plate 334 is connected to the base plate 33 through a connecting portion 333; and a compression layer 335 is provided on the inner wall surface of the wiring harness fixing pressure plate 334, and the compression layer 335 adopts a 3mm thick silicone layer to prevent wire wear.

[0040] like Figure 1-5 The supporting longitudinal beams 2 form an integral frame through the connecting beams 22. The limit blocks 14 are made of elastic rubber, ensuring structural stability while allowing for micro-deformation to transmit pressure. The wiring harness retention system in the mounting assembly 3 can simultaneously secure 12 cables. The mounting holes B331 on the base plate 33 are precisely aligned with the sensor holes, ensuring that any sensor can be removed independently during maintenance without affecting the overall wiring.

[0041] like Figure 6-7 A bending portion 332 is integrally formed on one edge of the base plate 33 and abuts against the inner wall of the slot plate 30 ; a mounting hole B331 is provided on the base plate 33 for use with the mounting hole A301 .
