In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Fig. 1 is a schematic view showing the construction of the door lock system of the present invention. As shown in fig. 1, the door lock system includes: a door lock main body 101, a distance sensing module 102, a camera module 103, a door lock management module 104 and a mobile device 105;
the distance sensing module 102 and the camera module 103 are both connected with the door lock management module 104 fixed on the door lock main body 101; the distance sensing module 102 and the camera module 103 are adjacent to each other, and the distance between the two is small, and the distance data detected by the distance sensing module 102 can be equivalent to the distance of the object from the camera module 103. The image output end of the camera module 103 is connected with the data input end of the door lock management module 104.
The distance sensing module 102 is configured to detect whether an object such as a mobile device is near the door lock main body 101. When the distance sensing module 102 and the camera module 103 are located on the door lock main body, distance data obtained by the distance sensing module is the distance between an object such as a mobile device and the door lock main body 101; when the distance sensing module 102 and the camera module 103 are not located on the door lock main body 101, the distance of the mobile device from the door lock main body 101 can also be determined according to the distance data obtained by the distance sensing module 102, so as to detect whether an object such as the mobile device is close to the door lock main body. The distance sensing module 102 can be implemented by an ultrasonic sensor, and can also be implemented by other methods according to actual requirements, for example, an infrared distance sensing method. When an object such as a mobile device is within a set distance range from the periphery of the door lock main body 101, the door lock management module 104 controls the camera module 103 to turn on the camera function.

After receiving the installation package of the door key application program returned by the management background, the user installs the installation package on the mobile equipment. When the lock needs to be unlocked, the user operates the door key application program on the mobile equipment, after the user identity authentication is successfully carried out, the door key application program generates a door key bar code, and the bar code is displayed to the door lock main body, so that the unlocking operation can be realized. In the whole unlocking process, the mobile equipment does not need to be networked, the leakage risk caused by network transmission is avoided, and the use safety performance is improved.
Implementations of the door lock body 101 include, but are not limited to, an embedded system. For example, a raspberry development board can be used as a control core of a door lock main body, an SD memory card is loaded into an SD card slot on the raspberry development board for installing an operating system, application software (including but not limited to a door lock management module) and storing data, and functions of distance detection, barcode scanning and analysis, door key data verification, door lock opening and the like are realized by connecting a distance sensor, a camera, a relay and the like on pins or a USB interface of the raspberry development board and matching with the door lock management module.
