The intelligent cattle barn achieves automated functions such as automatic water changing, automatic feeding, and intelligent monitoring and reporting, enabling unattended intelligent farming. This intelligent cattle barn includes an inner shed and an outer shed. The inner shed is enclosed by four walls and a roof, with one side featuring an inner door that connects to the outer shed. The inner shed is equipped with an infrared temperature sensing device, a temperature regulation device, and an automatic feeding and control system. Both the infrared temperature sensing device and the temperature regulation device are signal-connected to the control system. The automatic feeding system includes water supply and feed replenishment. This utility model patent utilizes automation technology to automatically provide water and feed, while also enabling real-time recording, achieving unattended operation, reducing labor costs in cattle farming, and facilitating large-scale breeding.
