RFID identification method of pet water and food feeding machine

The invention discloses an RFID identification method for a pet water and food feeding machine, and the method comprises the steps: obtaining the positioning information of the pet water and food feeding machine, and constructing a signal field of an RFID signal along the outside through the positioning information; a first distance between the pet and the pet water and food feeding machine is monitored, and the staying time of the pet is measured and calculated; if the staying time of the pet exceeds a preset staying time threshold value, adjusting a radiation range of a signal field of the RFID signal based on the first distance so as to detect an RFID sensor of the pet; the feeding information of the pet is recognized based on the response of the RFID sensor of the pet, and the working state of the water and food feeding machine for the pet is adjusted according to the feeding information; when the water quantity of the water and food feeding machine for the pet reaches a preset water quantity threshold va
