detailed description

In order to make the purpose, technical solutions and beneficial effects of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Fig. 1, the new type of intelligent lock of the utility model, the lock includes a wireless communication module 101, a controller 102, a brake module 103, a camera 104, a power module 105, and a memory 106, wherein:

The power supply module 105 is connected to the wireless communication module 101, the controller 102, the braking module 103, the camera 104, and the memory 106;

The camera 104 is aimed at the position unlocked by the user, and the signal output end of the camera 104 is connected to the signal receiving pin of the controller 102;

The control signal output pin of the controller 102 installed with picture comparison software is connected to the control signal input end of the braking module 103;

The data exchange port of the wireless communication module 101 is connected to the data exchange pin of the controller 102, and the wireless communication module 101 is connected to the control terminal of the lock by wireless means;

A memory 106 that stores pictures in advance is connected to the controller 102 .
