Smart door lock with color recognition

The invention relates to a smart door lock, in particular to a smart door lock with color recognition.

According to the general common intelligent door lock, the access control identification system includes a QR code, a radio frequency identification system and a biometric identification system. The combination with the back-end device can be applied to the access control and personnel access control, and also used in general family access control. System and building access control, vehicle thresholds and other applications. It can replace the access control of traditional door lock keys or magnetic stripe cards, and combine with the functions of existing items in life to reduce the carry-on items and solve the complicated problems of carrying items.

However, the conventional intelligent door locks need to be combined with the back-end equipment to be used, and cannot be operated independently by a single machine, so the cost is relatively increased. Moreover, the wisdom of the smart door lock verification method and the lack of cipher code coding are limited, and the code is easy to copy, so it is easy for the person concerned to snoop and crack, and its security and confidentiality are obviously insufficient. Therefore, the customary intelligent door locks need to be improved.

The main object of the present invention is to provide a smart door lock with color recognition, which can combine the access control service and image color recognition, thereby improving the security and confidentiality of the intelligent door lock.

A secondary object of the present invention is to provide a smart door lock that is color-coded and capable of operating independently, thereby reducing the cost of access control.

In order to achieve the above objective, the invention provides a color-recognition smart door lock, which mainly comprises an input device, has a screen, and can input a password and provide conversion and coding into a color code through a software, and The color code is displayed on the screen. The color code displayed on the screen is captured by a capture module, and the camera device is coupled to a decoding device to decode the captured color code. And output one of the decoded cryptographic signals after decoding. At the same time, the capture output module is connected to an identification comparison module, which can recognize the identification cryptographic signal outputted after decoding the color code, and can output a comparison result signal. The control unit connected to the identification comparison module is capable of receiving the comparison result signal. And the control unit is connected to a door lock, which has an electronic access control unit, and the electronic access control unit is controlled by the control unit, thereby controlling the door lock to be opened or locked.

The smart door lock provided by the invention is color-coded, and the backlight color on the screen of the input device is converted into a password as a password for the access control. Its high plasticity for color coding makes color image layout and transformation methods more diverse, thus providing higher security and confidentiality. The individual identification rate is high and can be operated independently. It can be applied to various access control measures and save the cost of general access control.

Please refer to the first and second figures, which are schematic diagrams and schematic diagrams of a preferred embodiment of the present invention, including:

An input device 10 is a smart phone 11 having a screen 12 and inputting a password and providing a transfer through the APP application software of the smart phone 11 The code is transcoded into a color code and the color code is displayed on the screen 12. The color code displayed on the screen 12 is displayed according to the color code, and a single color or a plurality of colors can be displayed on the screen 12 at the same time, and the color arrangement is used as the identification, wherein when the plurality of colors are simultaneously displayed on the screen 12 The password content may be represented by different gradation diagrams according to the coding. In the embodiment of the present invention, the gradation diagram may be a concentric circle or a rectangular strip, but this is only an embodiment, not a limitation. The implementation of the creation.

The output module 20 has an imaging device 21 that captures the color code displayed on the screen 12 of the input device 10, and the camera device 21 is coupled to a decoding device 22, which can capture the image. The color code is decoded, and one of the decoded identification cipher signals is output.

An identification comparison module 30 is connected to the capture output module 20 to identify the identification cryptographic signal after decoding the color code, and can output a comparison result signal.

A control unit 40 is connected to the identification comparison module 30 and is capable of receiving the comparison result signal.

A data storage module 50 is connected to the identification comparison module 30 and to the control unit 40 for storing passwords and basic function messages.

A door lock 60 has an electronic access control unit 61 connected to the control unit 50 for controlling the electronic access control unit 61 and controlling the door lock 60 to be opened or locked by the electronic access control unit 61. In the preferred embodiment of the present invention, the electronic access control unit 61 is an electromagnetic lock, and the electromagnetic lock is controlled by the control unit 50, and the electromagnetic lock is further controlled to open or lock the door lock 60.

For a further understanding of the structural features of the present invention, the application of the technical means, and the intended effect, the manner of use of the present invention will be described. It is believed that the present invention may be further understood and understood as follows: As shown in the second figure, the input device 10 of the present invention is the smart phone 11 having the screen 12, and can input a password, and convert and encode the color code into an color code through an APP application software, and the color code is It is displayed on the screen 12 by its backlight color.

Referring to the first figure, and referring to the third figure, which is a flow chart of the preferred embodiment of the present invention, the input device 10 is first placed in the capture device of the capture output module 20. Before 21, the color code is captured, and the captured color code is decoded, and the decoded identification code signal is outputted to the identification comparison module 30 connected to the capture output module 20, and the recognition ratio is After the color code is decoded, the identification password signal determines whether the password is consistent. If the password does not match, the password is not activated. If the password is consistent, the comparison result signal is output to the control unit 40. The electronic access control unit 61 is controlled by the control unit 40, and the door lock 60 is unlocked by the electronic access control unit 61. And the data storage module 50 connected to the control unit 40 can determine whether the door lock 60 is opened by setting the basic function message, and automatically lock the door lock 60 if it is not opened for a time. .

Hereafter, the features of the present invention and the achievable expected effects thereof are as follows: the intelligent door lock of color identification of the present invention is combined with a smart mobile phone application commonly used in living, and converted into a password by its backlight color. As the access control password, it can not only operate independently, but also save the cost of general access control. The high degree of plasticity of color coding makes the color image arrangement and transformation method more diverse, so it has a considerable degree of protection for confidentiality and cracking, and provides high security and confidentiality.
