Embodiment 1

[0031] Such as figure 1 , 2 As shown, a kind of anti-daze device in class of the present invention comprises controller 1, camera device 2 with facial recognition function, and electric sprayer 3; Camera device 2 and electric sprayer 3 are electrically connected with controller 1 respectively; Controller 1 Compare the facial information successively collected by the camera device 2 and control the electric sprayer 3 to spray.

[0032] The electric sprayer 3 includes a liquid storage tank, an electric pump, a connecting pipe, a spray pipe, and a spray nozzle. The electric pump is installed at the mouth of the liquid storage tank. The input port of the electric pump is connected with the nozzle; the output port of the electric pump is connected with the nozzle through the nozzle; the electric pump is electrically connected with the controller 1.

[0033] Irritant liquid is housed in this liquid storage bucket, and irritant liquid is made up of 70 parts of water, 20 parts of vi...

Embodiment 2

[0037] Based on the anti-trance device in class of embodiment 1, its anti-trance method in class is:

[0038] Step 1: Fix the camera device 2 on the edge of the front of the desk, the camera device 2 automatically sets the face and focuses on the face;

[0039] Step 2: The camera device 2 takes a photo of the face for the first time, and sends the photo to the controller 1; the controller 1 stores the photo and starts timing;

[0040] Step 3: After the timing is over, the controller 1 controls the camera device 2 to take a second photo of the face; the controller 1 compares the pictures taken on both sides and executes the setting action according to the comparison result;

[0041] Step 4: When the controller 1 judges that the face is in a trance state according to the comparison result, the controller 1 controls the electric sprayer 3 to spray; when the controller 1 judges that the face is in a non-trance state according to the comparison result, the controller 1 stores the s...

Abstract

The invention relates to a device for preventing a daze in class, and belongs to the field of student supplies. The device comprises a controller, a camera device with a facial recognition function and an electric sprayer; the camera device and the electric sprayer are electrically connected with the controller separately; the controller compares facial information sequentially collected by the camera device and controls the electric sprayer to conduct spraying. The human face is recognized, the picture information of the human face is sequentially compared, and whether a human body is in a daze state or not is judged by comparing the contact ratio of pictures; the daze time is often three minutes or above when the human body is in the daze state, the position of the human face cannot change in the daze process, the condition that the human face does not change can be judged through before and after comparison on the pictures, therefore, whether the human body is in the daze state or not can be judged through the camera device, and the daze state is interrupted by stimulating the human body through electric spraying.

Description
