Rotary intelligent bookcase and method for controlling and reducing rotary torque of motor

Abstract

The invention relates to a rotary intelligent bookcase and a method for controlling and reducing the rotary torque of a motor. A rotary body is arranged in a shell and comprises a driving shaft, the driving shaft is provided with multiple rotary discs side by side in the axial direction of the driving shaft, and the rotary discs are provided with multiple book case plates. The lower end of the driving shaft is connected with the servo motor through a speed reduction device. An electromagnetic stabilizing device comprises an electromagnet which is located on the lower side of the rotary disc at the lowest end and has controllable magnetic force, and at least the rotary disc at the lowest end is made of a magnetic material. The magnitude of currents of the electromagnet is adjusted in real time according to the load change of the servo motor to control the magnitude of the magnetic force of the electromagnet, and electromagnetic attraction between the electromagnet and the corresponding rotary disc offsets the rotary inertia generated in the speed reduction process of the rotary body. An RFID intelligent rotary recognition unit is further included, and the RFID intelligent rotary recognition unit controls a system to record and store book cases corresponding to RFID tags when books are placed and regards the corresponding relationship between the RFID tags and the book cases as the reference for judging whether book placement positions are correct or not.

Description

technical field [0001] The invention relates to the field of intelligent storage cabinets, in particular to a rotary intelligent bookcase, its control and a method for reducing the rotary torque of a motor applied thereto. Background technique [0002] In the smart book or file automatic storage cabinets we come into contact with every day, fixed bookcases are basically used in a way similar to express cabinets, which store a small number of books and occupy a large space; while the existing rotary bookcases store a small number of books and have low positioning accuracy. Intelligently identify each book so that it must be put in according to the book grid number when it is placed, which is time-consuming, labor-intensive, and error-prone. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a revolving intelligent bookcase with reasonable structure, compact structure, large volume of books, high precision of revolvin...
