6. The intelligent pig house environment monitoring and control system according to claim 4 or 5, characterized in that: The data adjustment module, under the condition that it is determined that the proportion of areas with slow wind flow in the pig house does not meet the standard, determines to increase the opening of the vent by the first preset opening adjustment coefficient based on the comparison result that the difference between the gas infrared data value and the preset gas infrared data value is less than or equal to the preset difference.

7. The intelligent pig house environment monitoring and control system according to claim 4 or 5, characterized in that: When determining that the proportion of slow-flowing areas in the pig house does not meet the standard, the data adjustment module determines to increase the opening of the vent by a second preset opening adjustment coefficient based on a comparison result that the difference between the gas infrared data value and the preset gas infrared data value is greater than the preset difference.

8. The intelligent pig house environment monitoring and control system according to claim 7 is characterized in that: The feeding monitoring module determines that the feeding situation of the pigs in the pig house does not meet the standard after the vent opening is adjusted based on the comparison result that the total amount of food eaten by the pigs in the pig house is less than the total amount of food eaten threshold under the condition of determining to adjust the vent opening.

9. The intelligent pig house environment monitoring and control system according to claim 8 is characterized in that: When it is determined that the eating conditions of the pigs in the pig house after adjustment do not meet the standards, the data optimization module determines to increase the fresh air intake rate in the pig house by a preset air intake rate adjustment coefficient based on the comparison result that the relative difference between the total food intake threshold and the total food intake is less than or equal to the preset relative difference.

10. The intelligent pig house environment monitoring and control system according to claim 8 is characterized in that: When it is determined that the eating conditions of the pigs in the pig house after adjustment do not meet the standards, the data optimization module determines to increase the fresh air intake rate in the pig house by a preset air intake rate adjustment coefficient and to increase the turbid air outlet rate by a preset air outlet rate adjustment coefficient based on the comparison result that the relative difference between the total food intake threshold and the total food intake is greater than the preset relative difference.
