Anti-interference method of intelligent door lock and intelligent door lock thereof

Abstract

The invention provides an anti-interference method of an intelligent door lock and the intelligent door lock thereof. The method is applied to the intelligent door lock, and the intelligent door lock comprises a front panel and a rear panel, wherein the front panel is provided with a touch screen and a touch chip. The method specifically comprises the following steps that a controller is awakened by pressing a key on a rear panel; the controller judges whether the touch screen has normal interference or not through the touch chip; the controller judges whether the pressing time of the key is within a preset shake elimination time range or not; the controller judges whether the fingerprint collected by the fingerprint module is a human fingerprint or not; and when the three judgment results are all yes, the controller executes the door opening action. Safety is improved, and abnormal door opening and closing caused by factors such as environmental interference or human attack or hardware abnormity can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to an anti-interference method for an intelligent door lock and the intelligent door lock. Background technique [0002] With the development of door locks, fingerprint locks with higher security are becoming more and more common. Compared with mechanical locks, fingerprint locks have added a fingerprint identification module and an action motor. The fingerprint identification module controls the action motor to start after successful identification, and then Drive the lock cylinder clutch mechanism for unlocking and locking actions. [0003] However, in the existing fully automatic door locks, the high and low level input of the door switch button is directly controlled by the MCU, and the door opening and closing action is directly executed when the trigger level is detected. When the working environment of the lock is abnormal and subject to electromagnetic interference and s...

Problems solved by technology

[0003] However, in the existing fully automatic door locks, the door open / close button is generally directly controlled by the MCU for high and low level input, and the door is opened and closed directly when the trigger level is detected.

When the working environment of the lock is abnormal and subject to electromagnetic interference and static electricity interference, the individual level signal is no longer stable, and it is prone to malfunction events, which will bring bad experience to users
