Intelligent lock and unlocking/locking method

Abstract

The invention relates to the technical field of locks, and discloses an intelligent lock and an unlocking / locking method.The intelligent lock comprises a first sensor used for monitoring the motion state of the lock; the second sensor is used for receiving the instruction of the control module to start and detect the position of the lock; the driving module is used for receiving an instruction of the control module to drive a spring bolt of the lock to extend or retract; the control module is used for receiving the motion state of the lock and sending a starting instruction to the second sensor when the motion amplitude of the lock exceeds a preset first threshold value; when the position of the lock is within the calibration position range and the movement amplitude of the lock is lower than a first threshold value, an unlocking or locking instruction is sent to the driving module; the power supply is used for supplying power to the lockset. In the unlocking / locking process, the movement state of the lock is detected at first, then the second sensor is started to detect the position of the lock, unlocking / locking is conducted after the condition is met, energy consumption is reduced, and meanwhile accurate unlocking / locking can be achieved.

Description

technical field [0001] The present invention relates to the technical field of locks, in particular to an intelligent lock and an unlocking / closing method. Background technique [0002] When the smart lock used on the door realizes the automatic switch lock function, it needs to determine the position of the door first. For example, when it is determined that the position of the door is closed, and then combined with other conditions to determine that it needs to be locked, the smart lock controller will control the lock. The tongue pops out to complete the lock. In the prior art, there are the following three schemes for realizing automatic switch locks. One is to detect whether the door is closed through a mechanical switch, for example, to determine the position of the door by detecting whether the triangular tongue switch provided on the lock body is pressed, and then execute the switch lock. The second is to detect whether the door is closed through a magnet. Specifica...

Problems solved by technology

Usually, smart locks are powered by four 5# dry batteries, and can only have a quiescent current of <200uA when working. If you directly use MEMS chips such as geomagnetic sensors to detect the position of the door, you need to keep the geomagnetic sensor in the normal open state and continuously obtain geomagnetic signals for 24 hours. , its power consumption cannot meet the requirements of the industry standard

For the user, the number of times of opening and closing the door is limited every day, so continuous detection of the position of the door will cause unnecessary waste of battery power

[0004] In addition, in the third scheme, there is an error problem when closing the lock

The heading accuracy of the commonly used geomagnetic sensor can only reach 1 degree at present. If it is installed on a door with a width of 1m, its translation error is about 17mm. When closing the lock, an error of more than 3mm will cause the deadbolt to not be accurately introduced. Therefore, when the door has not fully reached the closed position or is not completely stationary, the lock action signal is issued, resulting in failure to lock.
