Locking control method based on door leaf behavior state

Abstract

The invention discloses a locking control method based on a door leaf behavior state. The locking control method based on the door leaf behavior state comprises a lock body, a controller, a rate gyroscope sensor and an acceleration sensor, wherein the controller is used for controlling unlocking of the lock body, the rate gyroscope sensor and the acceleration sensor are in signal connection with the controller, the rate gyroscope detector provides an angular velocity change characteristic value to the controller when the rate gyroscope detector moves along with a door leaf, when the acceleration sensor moves along with the door leaf, the acceleration sensor provides an acceleration change characteristic value to the controller; and the controller is used for obtaining the current data table when the door leaf is continuously obtained in different states when the door leaf moves, and carrying out state analysis on the positions of the data in the current data table on the coordinates, and implementing corresponding locking control. In this way, the problem of sensing drift of the gyroscope can be well solved, and the data table is particularly a closed position data table, a door closing vibration data table or a door closing and moving data table, and whether the actual position of the door leaf is located at the correct locking position or not can be judged accurately.

Description

Technical field[0001]The invention relates to a door lock controlled by a gyroscope, in particular to a method and system for realizing lock control in a door lock by using a combination of a gyroscope chip and a controller.Background technique[0002]In the prior art smart door locks, the determination of whether the door leaf has been closed in place is suitable for locking action generally adopts infrared detection methods, door sensor detection methods, mechanical switch detection methods, etc. Infrared detection methods Infrared detection devices generally need to transmit infrared light, and an infrared transparent window needs to be set on one of the two sides of the door inner panel, which is not good-looking and because the door is divided on the left and right sides, the left and right sides of the inner panel are required. The same launch tube and window must be installed, the structure is complicated; in addition, an infrared reflection device must be installed on the side...
