It should also be understood that terms such as those defined in a general dictionary should be understood to have meaning consistent with the meaning in the context of the prior art, and will not be idealized or excessive unless specifically defined as here. The formal meaning is explained.

Referring to Figure 1, an embodiment of an automatic feeding method of the present invention is proposed, the method comprising the steps of:

S11. Detect whether a pet is close. When a pet is approaching, the process proceeds to the next step S12.

S12. Detect the height of the pet.

S13. Adjust the height of the feeding box according to the height of the pet.

In the embodiment of the present invention, the automatic feeding device includes a base 100, a strut 200 and a feeding box 300. The feeding box 300 is movably connected to the strut 200 and can slide up and down along the strut 200.

In step S11, the automatic feeding device detects whether a pet is approaching in real time or at a time. The automatic feeding device can detect the distance between the pet and the automatic feeding device through the distance detecting device such as the sensor unit and the camera, thereby determining whether the pet is close.

Optionally, the struts 200 of the automatic feeding device are provided with a sensor unit, and the sensor unit detects whether there is a pet approaching, and the sensor unit may be an ultrasonic sensor, an infrared sensor or the like. Specifically, the automatic feeding device detects whether there is an obstacle within a preset distance (for example, within 1 meter) through the sensor unit, and when there is an obstacle in the preset distance, it is determined that the pet is close. For example, infrared rays can be emitted by an infrared sensor and infrared rays reflected from an obstacle can be received, and the distance between the obstacle and the automatic feeding device can be calculated from the time difference between the emitted and received infrared rays.

In a preferred embodiment, the automatic feeding device detects whether there is an obstacle within a preset distance (for example, within 1 meter) through the sensor unit; when there is an obstacle within the preset distance, the plurality of detections are continued, according to the distance of multiple detections. It is judged whether the distance of the obstacle gradually decreases; when the distance of the obstacle gradually decreases, it is determined that the pet is approaching. That is to say, the automatic feeding device determines that the pet is close to the automatic feeding device only when it detects that the pet is within a preset distance and gradually approaches, thereby improving the accuracy of the judgment and preventing misjudgment.

Optionally, a camera 200 is disposed on the pillar 200 of the automatic feeding device, and the camera detects whether a pet is approaching. For example, adjusting the angle of the camera so that the camera is aligned with the preset area, the automatic feeding device collects the image in the preset area through the camera, and determines whether there is a pet in the image through image recognition technology, and when there is a pet in the image, it is determined. There are pets close by.

Further, in other embodiments, when a pet exists in the image, the automatic feeding device further continues to detect whether the distance between the pet and the automatic feeding device is gradually decreased, and when the distance is gradually decreased, it is determined that the pet is approaching, thereby improving The accuracy of the judgment is to prevent misjudgment.

In step S12, when a pet approaches, the automatic feeding device detects the height of the pet.

Specifically, the automatic feeding device controls all the sensor units to perform pet detection, determines which sensor units detect the pet, detects the pet sensor unit as a reference unit, and determines the height of the pet according to the height of the reference unit from the highest ground. For example, the height of the reference unit that is the highest from the ground is directly determined as the height of the pet.

Taking the sensor unit as an infrared sensor as an example, the automatic feeding device activates all the infrared sensors, and controls all the infrared sensors to emit infrared rays outward, and then determines whether the infrared sensor is within a preset time (eg, infrared rays are required to travel within 0.2-0.3 meters). Time) receiving the reflected infrared rays; if an infrared sensor receives the reflected infrared rays within a preset time, it is determined that the infrared sensor detects the pet. Finally, the highest infrared sensor from the ground is found from the infrared sensor that detects the pet, and the height of the infrared sensor is determined as the height of the pet.

Those skilled in the art can detect the height of the pet by using a plurality of sets of sensor units with different position heights, and can also detect by using other technical means in the prior art. For example, the height of the pet can be detected by the binocular camera. The description of the present invention will not be repeated here.

In step S13, after detecting the height of the pet, the automatic feeding device adjusts the height of the feeding box according to the height of the pet, such as controlling the feeding box to slide up or down along the pillar of the automatic feeding device for a distance to make the feeding box The height matches the height of the pet, making it easier and more comfortable for the pet to eat.

Further, when at least two pets are in close proximity, the automatic feeding device adjusts the height of each pet to adjust the height of the feeding box. For example, adjust the height of the feeding box based on the height of the lowest pet, or adjust the height of the feeding box based on the average height of all pets, or adjust the height of the feeding box based on the height of the highest priority pet. ,and many more.
