Automatic ventilation system and automatic speed regulating and partitioning method thereof

Abstract

The invention provides an automatic ventilation system and an automatic speed regulating and partitioning method thereof. The automatic ventilation system comprises a plurality of fans and at least one environment detector, wherein each fan comprises a speed regulating device, and the speed regulating devices controllably regulate the rotating speed of the fans; the at least one environment detector detects an external environment and outputs environment information; the automatic ventilation system can process the environment information and output execution information; and the speed regulating devices are further controlled to regulate the rotating speed of the fans, so as to change the amount of ventilation of the automatic ventilation system.

Description

technical field [0001] The invention relates to the field of fan control, in particular to an intelligent ventilation system and its automatic speed regulation and partition method. Background technique [0002] In large-scale livestock farming, the farmer usually builds a large farm in which the livestock are raised. During the breeding process, the livestock in the farm produce some harmful gases, including carbon dioxide and ammonia, as well as the waste gas produced by the mixture of excrement and food residues produced by the livestock. The mixture of these harmful gases and the waste gas will cause certain damage to the growth of livestock Seriously, it can even lead to illness and even death of livestock. [0003] Therefore, in large farms, ventilation is an essential measure. Generally, a plurality of ventilators are arranged in the side wall of the farm, and when the ventilators perform ventilation operation, harmful gas and waste gas therein are discharged outsid...

AI Technical Summary

Problems solved by technology

Controlling the ventilation volume of the farm by the above method, on the one hand, consumes a lot of energy. The energy consumed by turning on and off the fan is often greater than that of running it all the time. On the other hand, it is difficult to adjust the fan in time. In other words, if there are a few days in the whole summer when the internal concentration of harmful gases is relatively high, but it cannot be adjusted in time

[0006]In addition, large-scale farms occupy a large area and the fans are widely distributed, which makes the overall operation and maintenance more inconvenient
