Aquaculture water quality PH value multi-parameter control system and control method thereof

Abstract

The invention discloses an aquaculture water quality PH value multi-parameter control system. The control system includes an aquaculture area (1), T water quality detection bodies (2) are arranged inthe aquaculture area (1), each of the water quality detection bodies (2) is connected with a PH value controller (3), and the PH value controller (3) is also connected with an oxygen supply system (4), a water exchange system (5) and a top application and fertilizer supply system (6); and the PH value controller (3) predicts and controls the oxygen supply system (4), the water exchange system (5)and the top application and fertilizer supply system (6) according to aquaculture data detected by the water quality detection bodies (2), thereby adjusting the PH value of a water body in the aquaculture area (1). The beneficial effects are that the aquaculture water quality PH value multi-parameter control system is high in data precision, is reliable and safe, adopts automatic control, does notneed artificial participation, and is intelligent and convenient.

Description

technical field [0001] The invention relates to the technical field of aquaculture water quality detection, in particular to an aquaculture water quality pH value multi-parameter data acquisition device and a data acquisition method. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. The requirements for water quality are particularly important in aquaculture, among which the PH value, oxygen content, algae content, light, temperature, transparency, salinity, ammonia nitrogen content, etc. of water quality all have an impact on the growth of aquatic animals and plants. [0003] In particular, in the water quality of aquaculture, the pH value is particularly important for the growth of aquatic animals and plants. An unsuitable pH value will destroy the supply of phosphate and inorganic nitrogen compounds in water production. If the pH value of aquaculture water is alkali...

AI Technical Summary

Problems solved by technology

[0005] When the method of topdressing is used, artificial control is adopted, and the amount of fertilizer cannot be grasped, which may easily cause low or high pH value, poor control accuracy, and the implementation method also adopts the method of manual sprinkling, which is uneven and untargeted.

The PH value of different locations and different water levels in the breeding area is also different. The use of topdressing special fertilizer for aquatic products will easily cause changes in the ammonia nitrogen content of the water body, and topdressing will easily cause excessive topdressing, which will cause irreversible losses.

[0006] The method of changing water cannot be applied frequently. Frequent water changes will destroy the living environment of aquatic animals and plants. Although the PH has been adjusted, the content of other substances in the water body has undergone tremendous changes, which is prone to large-scale aquatic animal and plant living environments. Affected, ranging from slow growth to death

[0007] In summary, in view of the defects of the existing technology, it is necessary to propose a technology to overcome the problem that the pH value of aquaculture water is difficult to control
