Method for calculating water intake of pet water dispenser

The invention relates to a method for calculating the water intake of a pet water dispenser, which comprises the following steps of: S1, acquiring whether a pet arrives or not, and if not, acquiring an initial weight value and an initial stable timestamp; if yes, setting a countdown time and starting countdown; s2, setting a time interval needing to be monitored, and obtaining a weight difference value before and after each time interval; s3, judging whether the weight difference value is within a normal range or not, and if yes, resetting the countdown time and repeating the step S2; if not, abnormal values are calculated and superposed to obtain an abnormal total value; s4, whether the pet leaves or not is known, if yes, the current weight value and the current stable timestamp are obtained, and the difference value of the current weight value and the current stable timestamp is calculated to obtain the initial water intake; s5, judging whether the initial water intake is within a normal water intake range
