Hog house sow oestrus identification system and application method thereof

The invention relates to the field of livestock breeding equipment, and discloses a hog house sow oestrus identification system and an application method thereof. The hog house sow oestrus identification system comprises a plurality of sow single fences, a controller, fixing pipes and a plurality of ultrasonic sensors, and the fixing pipes are transversely arranged at the upper ends of the sow single fences; and the ultrasonic sensors are arranged in the length direction of the fixing pipes, each sow single fence corresponds to one pair of ultrasonic sensors, the ultrasonic sensors are used for obtaining distance information data between sows in the corresponding sow single fences and the ultrasonic sensors, and the ultrasonic sensors are electrically connected with the controller. The ultrasonic sensors are arranged in all single sow houses, so that the hog house sow oestrus identification system is high in accuracy, fast in time efficiency, simple to operate, small in labor amount of workers and low in cost
