Multistory pig building could make full use of land resources, and had the advantages of improving production efficiency per unit area and reducing environmental pollution area. However, due to the different environmental requirements of different floors in the multistory pig building, it was difficult to accurately control the environment in the multistory pig building. In order to study the precise control scheme of multistory pig building environment, ANSYS FLUENT software was used to optimize and improve the airflow field distribution of multistory pig building based on computational fluid dynamics （CFD）. Based on the standard k-ε turbulence model, the airflow field in the multistory pig building was simulated, and the ventilation position in the piggery was adjusted and optimized. The results showed that the optimized design scheme could make the airflow field in the piggery more uniform and avoid large environmental deviation in the same piggery. Finally, based on the optimized design scheme, PLC was used to design and realize the precise control of the environment in the multistory pig building.
