technical field

The invention relates to an automatic control system and method for an aerator, in particular to an automatic control system and method for an aerator for aquaculture ponds.

Background technique

In recent years, the global aquaculture industry has developed rapidly, among which my country's development occupies an important position. According to FAO data, the current global marine and freshwater aquaculture production is as high as 45 million tons, of which China's aquaculture production is about 32 million tons, accounting for more than 71% of the global aquaculture production (FAO, 2002). The total output of aquaculture in my country accounts for more than 60% of the total output of my country's fishery, and it has become the only country in the world where the output of aquaculture exceeds the output of fishing.

The aquaculture industry has always been a labor-intensive industry, and labor costs account for 12-17% of the total production cost. With the continuous increase in employee wages, this ratio is still on the rise. Even so, the aquaculture industry still has difficulties in recruiting workers. question. Therefore, it is unsustainable to rely on low-cost labor to compete. It is necessary to increase the level of investment in technology and equipment, and promote enterprise expansion with low employment or even no employment growth, so as to buffer the impact of labor shortage on the operation of the breeding industry.

Aquaculture ponds In aquaculture, the dissolved oxygen parameter in aquaculture water is a key value in aquaculture, which directly affects the quality and even the survival rate of aquatic products. In the usual misunderstanding of production, it is believed that the aeration machine can solve the problem of dissolved oxygen by increasing the oxygen in the culture pond for a long time. However, the long-term operation of the aerator does not bring about the optimal oxygenation effect, but causes a waste of resources. It has been verified by experiments that turning on the water truck all day cannot provide the optimal oxygenation, and the intermittent and time-segmented water truck can maintain the optimal oxygenation effect. The commonly used oxygenation methods in the industry are through manual regular inspections, and the oxygenation operation is carried out regularly on the aquatic ponds. Although this can realize the regular oxygenation of the aquatic ponds, it is followed by an increase in the labor intensity of the operators, and Manual operation cannot effectively increase oxygen in aquatic ponds for a long time, so that the breeding environment of aquatic ponds cannot be effectively guaranteed.
