Detailed ways

The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , the alarm clock 10 provided by the embodiment of the present invention is used to wake up the user, especially the sleeping user.

The alarm clock 10 includes a main body 11 and an imaging module 12 , the imaging module 12 is arranged on the main body 11 and can rotate freely relative to the main body 11 .

The body 11 is generally square in shape with opposing front surfaces 111 and rear surfaces 112 . Wherein, there is a dial 110 in the middle of the front surface 111 to display the time and a reminder module 117 for reminding the user that the alarm clock time has arrived, and the rear surface 112 has an alarm clock button 113, a correction button 114, a battery box 115 and a start button 116 .

The prompting effect of the prompting module 117 can be voice prompting (for example, lazy insects get up, etc.), music, songs or bird calls.

Of course, the main body 11 can also be in other shapes, such as various shapes such as circle, triangle, trapezoid and so on.

The alarm clock button 113 is used to set the alarm clock time, the correction button 114 is used to correct the dial 110 to accurately display the time, the battery box 115 is used to accommodate the battery to provide electric energy to the dial 110 and the imaging module 12, and the start button 116 is used to start the acquisition. The imaging module 12 takes images, and the activation button 116 has two modes of automatic activation and manual control.

The dial 110 can display Arabic numerals, Roman letters, or numbers. The shape of the dial 110 may be various shapes such as a circle, a square, an ellipse, or a triangle.

The main body 11 has a processing unit 13 and a storage unit 14. The storage unit 14 is used to store the images obtained by the imaging module 12. The processing unit 13 is used to process the images in the storage unit 14 and control the prompting module 117 according to the processing results. Whether to continue prompting and whether the imaging module 12 continues to acquire images.

Please refer to Fig. 4, the working mode flow process of the alarm clock 10 of the embodiment of the present invention, it comprises the following steps:

S 1. Adjust the shooting direction of the imaging module and obtain the first image when there is no one in the preset viewfinder.

Specifically, adjust the shooting direction of the imaging module 12 so that its shooting range is focused on the area where the user wants to sleep on the bed, that is, the preset viewfinder. Then, the user manually presses the start button 116 to make the imaging module 12 obtain The first image when there is no one in the sleeping area is stored in the storage unit 14, the first image is the image that the user is not lying in the sleeping area.

S2, setting the alarm clock time.

Specifically, the user sets the alarm clock time through the alarm clock button 113, such as the time to be woken up at 6:00, 7:30, and so on.

After setting the alarm clock time, the user can lie down in the sleeping area and fall asleep.

Of course, the alarm clock can also be set first, and then the imaging module 12 can be activated to capture the first image.

S3, the alarm clock time is up, and the prompt module prompts that the time is up.

Specifically, when the alarm time is up, the prompt module 117 will automatically send out a prompt sound.

S4, the imaging module acquires a second image at a preset viewing position.

Specifically, as soon as the alarm clock time comes, the imaging module 12 will automatically start acquiring the second image of the sleeping area in real time under the control of the processing unit 13 and store it in the storage unit 14 .

S5, comparing the first image and the second image.

Specifically, the processing unit 13 analyzes and compares the first image stored in the storage unit 14 with the second image, and if the comparison result finds that there is a person's image (such as the user's image) in the second image, then return to S4 to control the prompt. The module 117 continues to remind the user that the time has come and the user should get up, and the imaging module 12 continues to obtain the second image of the sleeping area until the processing unit 13 analyzes the image of no one in the second image, which proves that the user has left the sleeping area After waking up, S6 is executed: the prompting module stops issuing prompts (specifically, the processing unit 13 controls the prompting module 117 to stop issuing prompts and the imaging module 12 stops taking pictures).

Specifically, the processing unit 13 can use, for example, image array comparison to determine whether there is a person in the second image. When the difference ratio between the first image and the second image exceeds a predetermined value, such as 70% or other values, it is determined There is a portrait in the second image.

Optionally, a plurality of predetermined values of the difference ratio can also be pre-stored in the processing unit 13, which depends on the distance between the alarm clock 10 and the sleeping area, for example, it is far away from the sleeping area, correspondingly the first image and the second image If the proportion of the sleeping area in the image is small, the difference ratio is small; otherwise, the difference ratio is large.

In short, when the alarm clock time comes, the imaging module 12 acquires the image of the sleeping area in real time, and the processing unit 13 compares the image pre-stored in the storage unit 14 with the image acquired in real time, and according to whether there is a person in the image acquired in real time image, thereby determining whether the reminder module 117 continues to send out the sound that the reminder time is up, and the image of someone continues to send out the reminder, otherwise, it stops sending out the reminder sound.

The alarm clock 10 of this embodiment can obtain the image of the sleeping area according to the imaging module 12, can determine whether there are people in the sleeping area, and then control whether the alarm clock emits a sound to wake up the sleeper. Therefore, the alarm clock can judge whether to send an alarm according to the environment .

It can be understood that those skilled in the art can also make other changes within the spirit of the present invention for the design of the present invention, as long as they do not deviate from the technical effects of the present invention. These changes made according to the spirit of the present invention should be included in the scope of protection of the present invention.
