The invention discloses an intelligent door lock based on a three-axis magnetometer and a control method thereof. The door lock comprises a three-axis magnetometer module which is used for detecting and feeding back an electric signal representing position information of the door lock to an MCU, the MCU used for receiving and processing the electric signal which is output by the triaxial magnetometer module and is caused by changes of a magnetic field, forming a triaxial magnetometer position tracking curve according to the output electric signal and generating a corresponding switch lock control signal to an execution module according to the triaxial magnetometer position tracking curve, the execution module used for receiving a lock opening and closing control signal sent by the MCU, executing a corresponding action according to the lock opening and closing control signal and feeding back states of a limiting switch to the MCU, and a power supply module used for supplying power to the triaxial magnetometer module, the MCU and the execution module.
Description
technical field [0001] The invention relates to the technical field of automatic door locks, in particular to an intelligent door lock based on a three-axis magnetometer and a control method thereof. Background technique [0002] With the improvement of living standards, more and more families pay more attention to the safety of the family, and the door lock plays a pivotal role as the first line of defense of the family. [0003] As the utilization rate of smart locks is increasing day by day, people's safety requirements for smart locks are also increasing day by day. In addition to preventing from the way of unlocking, it is also necessary to defend from the aspect of locking. [0004] In the prior art, smart door locks generally use infrared and magnetic induction to automatically close the door. However, due to infrared and magnetic induction, misjudgments are likely to occur, so that the automatic lock cannot accurately locate the closed state, and thus cannot be lock...
