Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1, according to a first aspect of the present invention, there is provided an automatic lock breaking method, comprising the steps of: and after the unlocking verification is successful, judging whether the intelligent door lock generates displacement, and if so, executing the lock breaking operation of the intelligent door lock.
Specifically, the lock breaking operation includes: the linkage between the door handle and the door lock actuator is disconnected.
At present, the existing intelligent door lock can be actively/automatically unlocked after the user successfully unlocks and verifies the lock and delays for five seconds. The reason for this is that these five seconds are the door open time left for the user. However, if the user opens the door slowly, for example, the door opening time is longer than 5 seconds, that is, the door is not opened, the intelligent door lock automatically breaks, and in this case, the user needs to re-verify; conversely, if the user opens the door faster, for example, the door opening time is less than 5 seconds, i.e., the door has been opened, but the intelligent door lock has not been automatically disconnected, the intelligent door lock may be used by a malicious person, and the security of the intelligent door lock may be reduced. In the invention, when the unlocking verification of the user is successful, as long as the operation of displacing the door is detected, namely the user finishes the unlocking operation, the linkage device between the door handle and the door lock execution mechanism is disconnected, so that the door lock execution mechanism does not act when the door handle is operated, and the problems of repeated verification and safety caused by too fast or too slow unlocking of the user can be effectively avoided.
In one embodiment, whether the intelligent door lock displaces or not is judged through the measured parameters of the acceleration sensor. The acceleration sensor is generally composed of a mass, a damper, an elastic element, a sensing element, an adaptive circuit and the like. In the acceleration process, the sensor obtains an acceleration value by measuring the inertial force borne by the mass block and utilizing a Newton's second law, and the moving mode of the equipment can be obtained by analyzing the dynamic acceleration, and meanwhile, the acceleration generated by the traction force can be measured. Common acceleration sensors include capacitive type, inductive type, strain type, piezoresistive type, etc. according to the sensing element of the sensor.
The measured parameter of the acceleration may be a speed or an acceleration in a certain direction, etc. The measurement method of the acceleration sensor can refer to the measurement method in the prior art, and the invention is not described herein again. In addition, the displacement is angular displacement, namely the angular displacement generated when the intelligent door lock rotates by taking the door shaft as a rotating shaft and is opened.
In one embodiment, the operation of warning by an indicator light is added, and the operation is to avoid the phenomenon that the intelligent door lock is always in an unlocked state when the user passes the verification and the unlocking operation is not executed.
Specifically, when the unlocking verification is successful, the indicator light displays a first color, for example, the first color may be green. After the unlocking verification is successful, if the intelligent door lock does not produce displacement, the indicator light is changed from the first color to the second color, for example, the color of the indicator light is changed from green to red, so that the function of warning the user is achieved, and the user is reminded to take further operation.
In addition, if the intelligent door locks, the indicator light does not display any color.
In summary, the present invention replaces the operation of controlling the intelligent door lock by software in the prior art with the operation of controlling the intelligent door lock by hardware, so as to cancel the sticking time in the prior intelligent door lock, and execute the lock breaking operation as long as the intelligent door lock is displaced, thereby improving the security of the intelligent door lock.
According to a second aspect of the present invention, the present invention provides an intelligent door lock, which comprises a door handle 1 and a door lock actuator, wherein the door handle 1 controls the door lock actuator through a linkage device; the linkage device is connected with the processor, and the processor is used for executing the automatic lock breaking method. In addition, the processor is also connected to the acceleration sensor 2, as shown in fig. 2, the acceleration sensor 2 is a three-axis acceleration sensor, which includes a gyroscope 21, a rotating shaft 22, a balance ring 23, and a rotating wheel 24. An acceleration sensor 2 is provided in the door handle 1. The dashed arrows shown in fig. 3 are the movement paths of the doors.
According to a third aspect of the present invention, the present invention provides a computer readable storage medium having stored thereon a computer program which, when executed by a processor, implements the automatic lock breaking method as described above.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
