Problems solved by technology

The second is to prevent technical opening, and the ability of mechanical locks to prevent technical opening is very poor
[0004] When detecting the state of the door lock, an additional door lock state detection mechanism needs to be installed, resulting in high installation costs; at the same time, the existing alarm method is to realize the alarm when the smart door lock is damaged. There may be safety issues including personal safety even if the smart door lock is not damaged

Embodiment 1

[0107] Door lock state detection module 2 detection method provided by the present invention comprises:

[0108] (1) Acquiring the first signal detected by the inner bolt state detection component of the door lock and the second signal detected by the door rotation detection component.

[0109] (2) Judging the state of the bolt of the door lock by the first signal, and judging the switch state of the door where the door lock is located by the second signal.

[0110] (3) According to the state of the dead bolt and the state of the switch, it is judged whether the door lock is locked correctly.

[0111] The first signal provided by the present invention is magnetic flux, and the step of judging the bolt state of the door lock through the first signal, and judging the switch state of the door where the door lock is located through the second signal includes:

[0112] It is judged according to the magnetic flux whether the state of the dead bolt is fully extended.

[0113] The s...

Embodiment 2

[0124] Alarm module 7 alarm methods provided by the present invention include:

[0125] 1) Receive the request information to open the smart door lock.

[0126] 2) Make an inclusion judgment:

[0127] Judgment 1: judging whether there is request content in the request information that matches the preset unlocking information that triggers unlocking of the smart door lock.

[0128] Judgment 2: judging whether there is request content in the request information that matches the preset trigger alarm information of the smart door lock. If the first judgment and the second judgment are both yes, then execute the next step.

[0129] 3) Start the unlocking program of the smart door lock and start the alarm program of the smart door lock.

[0130] According to the present invention, when the first judgment is yes and the second judgment is no, only the unlocking procedure for starting the smart door lock is executed.

[0131] The unlocking information of the preset smart door lock...

Embodiment 3

[0136] The invention uses a matching program to match the input door lock password through the password matching module. Specifically include:

[0137] Step 1, carry out wavelet transformation on the image n times and retain the sub-image of the low-frequency part after wavelet transformation, then the width and height of the sub-image are the same as the original image The area of ​​the sub-image is equal to the area of ​​the original image Match within subimages. The improved normalized cross-correlation measurement method is used to traverse and search on the sub-images, and several matching points with high similarity are retained during the search process. After the search is completed, the matching points with high similarity are mapped to the search sub-region of the original image to be matched.

[0138] In step 2, the following steps are used for matching in each search sub-region, specifically: the width M and height N of the original image to be matched, and th...

Abstract

The invention belongs to the technical field of door lock alarm, and discloses a simple door lock alarm reminding system and method. The method comprises the steps of: collecting image data of a dooropener by a camera; detecting a door lock state by a door lock detection component; recognizing the collected human face by a recognition program; matching the input door lock password by a matching program; determining whether face recognition and door lock matching are correct or not by a determination program; performing alarm notification by an alarm according to determination of illegal invasion; and displaying the collected image data of the door opener by a display. Through the door lock state detection module, other door lock detection mechanisms do not need to be additionally installed on a door body or a door frame, the installation cost of door lock state detection is greatly reduced, and the original use environment of a door is not affected; and alarm can be completed by the alarm module on the premise that personal safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of door lock alarms, and in particular relates to a simple door lock alarm and reminder system and method. Background technique [0002] Electronic door locks emerged with the development of electronic technology. They are incomparable to mechanical locks in terms of convenience of use, anti-illegal opening, and intelligent management. Therefore, they are widely used in industries with high safety requirements. The common ones on the market are mainly magnetic cards, IC cards, TM cards, and radio frequency card electronic door locks. As a security product, door locks must be safe and stable. Safety can be measured from two aspects: one is resistance to vandalism, pranks and deliberate violent damage such as prying and drilling. In this regard, the mechanical strength of mechanical locks and electronic door locks can generally meet the requirements. Among all kinds of locks, only the rf card electronic loc...
