The intelligent shower method for pig farm personnel according to claim 8, characterized in that: Four ultrasonic sensors are distributed in four corners, and the calculation process of the total effective shower time X is as follows: (B1) The value of the ultrasonic sensor at the upper left corner is num1(i); the value of the ultrasonic sensor at the upper right corner is num2(i); the value of the ultrasonic sensor at the lower left corner is num3(i); the value of the ultrasonic sensor at the lower right corner is num4(i); the values ​​required by ultrasonic sensors at different positions at different times i are inconsistent; the total effective time of the shower is Shower spray time and after The effective time of free shower is calculated as follows: when hour, 25≤num1(i)≤40 25≤num2(i)≤40 25≤num3(i)≤40 25≤num4(i)≤40 when hour, (B1) g1 and g2 are greater than g3 and g4 are greater than 10. The intelligent shower method for pig farm personnel according to claim 9, characterized in that: The environmental temperature control controller receives the shower start signal from the shower controller through the CAN bus, and after a delay of Y seconds, turns on the bathroom heater or fan according to the temperature and humidity of the changing room inside the house and the changing room outside the house.
