The invention relates to the field of livestock and poultry breeding environment control, and particularly discloses a sheep house environment intelligent regulation and control system and method based on multiple sensors. The core of the method is that sheep house environment parameters are collected in real time through a sensor array, and meanwhile sheep flock behavior posture proportion characteristics are continuously extracted through a video analysis module; performing space-time fusion on the environment data and the behavior characteristics, inputting the environment data and the behavior characteristics into a pre-trained behavior-environment coupling model, and calculating a sheep flock discomfort index reflecting a real stress state of the sheep flock; based on the numerical value, the change direction and the rate of the index, a control strategy generator dynamically generates a staged and multi-device cooperative time sequence control instruction sequence to drive ventilation, cooling, heating and other devices to execute combined actions; the system performs effect evaluation according to behavior feedback after regulation and control, and optimizes a subsequent strategy accordingly. The system synchronously realizes accurate decision based on biological feedback, anti-collision control of multi-device cooperation and dynamic regulation and control with early warning capability.
