The invention relates to the technical field of control and adjustment, in particular to an efficient control method for a hog house ventilator. The method comprises the following steps: according to the use time of each ventilator, the air pressure of each sub-region at the current moment and the air pressure outside the hog house, calculating the influence factor of the effective work of each ventilator; according to the temperature, the humidity and the ammonia concentration of each sub-region at the current moment, calculating the required intensity of each sub-region; classifying the sub-regions according to the demand intensity to obtain target regions; according to the demand intensity of each sub-region in each target region, judging whether each target region needs ventilation or not; for any target area needing ventilation, according to the maximum value of the demand intensity of ventilation in the target area, the initial power of each ventilation fan corresponding to the target area is calculated; and obtaining the target power of each ventilator according to the actual rotating speed corresponding to the initial power of each ventilator and the influence factor of effective work. The method provided by the invention can effectively improve the environment in the pig house.
Description
technical field [0001] The invention relates to the technical field of control and regulation, in particular to an efficient control method for a ventilation fan in a pig house. Background technique [0002] A ventilating fan is a type of air-conditioning appliance that is driven by a motor to drive the fan blades to rotate and drive the airflow to exchange indoor and outdoor air, also known as ventilation fans. The purpose of ventilation is to remove the dirty air in the room and adjust the temperature, humidity and sensory effect. Ventilation fans are widely used for ventilation, dust removal and cooling in pig houses, chicken houses, factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Pig farms attach great importance to the environmental hygiene conditions of pig houses, because environmental conditions not only determine the growth rate of pigs and the quality of meat, but also are often related to various diseases. The ventilation fans of tradit...
