Description

QR code door lock

This creation is about an electronic door lock, especially a QR code door lock that unlocks after scanning the QR code displayed on the mobile device.

By the way, access control is the first gate of home security. The purpose of access control is to allow legitimate people to enter and keep illegal people out of the door.

The traditional door lock is the most convenient access control construction method used by most people. It has the advantages of being simple, easy to install, and does not require additional electricity, and it is also convenient to find someone who can unlock the lock in case the key is lost. Its most obvious disadvantage is that it is easy to be invaded, and an experienced thief can easily open almost all door locks. Secondly, the key is also one of the items that are easily forgotten or lost. In case of loss, you need to ask others for help. For fear of forgetting or losing the key, some people hide a spare key in an appropriate place near the door, and usually the thief knows this, so it provides a more convenient way for the thief to enter.

When microcomputers, especially microcontrollers, became popular, in order to avoid the trouble of key loss, increase the difficulty for thieves to unlock, and allow others to enter without keys, electronic locks appeared. At present, electronic locks can be roughly divided into three categories: button-type combination locks, chip-type and magnetic card-type electronic locks. Among them, although the button-type combination locks have the convenience of not having to carry the key and will not lose the key, the price of the combination lock is high. Paying for the extra waiting time, or even paying a fee, is quite an inconvenience indeed.

In view of the above-mentioned shortcoming in common use, creators research ways of improving at the above-mentioned shortcoming, finally have this creation to produce.

The main purpose of this creation is to provide a QR code door lock that can generate QR code graphics and transmit them to mobile devices.

The secondary purpose of this creation is to provide a QR code door lock that scans the QR code graphic displayed on the mobile device and unlocks it.

In order to achieve the above purpose and effect, the technical means adopted in this creation include a host, which includes: an electronically controlled lock unit, which receives a control signal to unlock; a photographing unit, which scans a QR code pattern; a microprocessor, which is electrically connected with the photographing unit and the electric control lock unit, receives and recognizes the QR code pattern, and generates the control signal, and the microprocessor internally stores the QR code pattern in advance; a wireless transmission unit, which is electrically connected to the microprocessor, receives and transmits the QR code pattern; thereby The wireless transmission unit transmits the QR code pattern to a preset mobile device, the photographing unit scans the QR code pattern displayed on the mobile device and transmits it to the microprocessor, and the microprocessor recognizes the QR code pattern to correctly generate the control signal to make the electronically controlled locking unit unlock.

According to the above structure, the mobile device may be a portable mobile device such as a smart phone, a tablet computer, a notebook computer, or a digital camera.

According to the above structure, the microprocessor can further update the QR code pattern periodically, and automatically transmit the updated QR code pattern to the wireless transmission unit, so that the wireless transmission unit transmits the updated QR code pattern to the mobile device.

In order to obtain a more specific understanding of the above-mentioned purposes, functions and characteristics of this creation, the explanations are as follows according to the accompanying drawings:

1: Host

11: Electric lock unit

12: Photography unit

13: Microprocessor

14: Wireless transmission unit

15: QR code graphics

2:Mobile device

〔Fig. 1〕 is the system block diagram of the preferred embodiment of this creation.

Referring to Fig. 1, it can be seen that the structure of this invention mainly includes a host 1, and the host 1 includes: an electric control lock unit 11, a photographing unit 12, a microprocessor 13 and a wireless transmission unit 14, wherein: the electric control lock unit 11 receives a control signal to unlock; the photographing unit 12 scans a QR code pattern 15; R code pattern 15; the wireless transmission unit 14 is electrically connected to the microprocessor 13 to receive and transmit the QR code pattern 15 to the outside.

In this way, the wireless transmission unit 14 transmits the QR code pattern 15 to the preset mobile device 2, and the camera unit 12 scans the QR code pattern 15 displayed on the mobile device and transmits it to the microprocessor 13. The microprocessor 13 recognizes that the QR code pattern 15 is correct and generates a control signal, so that the electronically controlled lock unit 11 unlocks.

It should be noted that the microprocessor 13 can further update the QR code pattern 15 periodically, and automatically transmit the updated QR code pattern 15 to the wireless transmission unit 14, so that the wireless transmission unit 14 transmits the updated QR code pattern to the mobile device 2; meanwhile, the mobile device 2 can be a portable mobile device such as a smart phone, a tablet computer, a notebook computer, or a digital camera.

Based on the above, the QR code door lock of this creation is indeed a novel and progressive creation, and an application for a new type patent is filed in accordance with the law; however, the content of the above description is only a description of the preferred embodiment of this creation, and all changes, modifications, changes or equivalent replacements based on the technical means and scope of this creation should also fall within the scope of patent applications for this creation.
