Multistep fishpond dissolved oxygen control system and control method thereof

Abstract

The invention discloses a multistep fishpond dissolved oxygen control system and a control method thereof. The system comprises a multistep fishpond, a variable frequency pump, a PLC controller and adissolved oxygen probe, wherein the multistep fishpond comprises multiple fishponds which are arranged in parallel from a high position to a low position; the variable frequency pump is arranged in the highest fishpond and is electrically connected to the PLC controller and controlled to supply water to the fishpond so as to form a waterfall flow from the higher fishpond to the lower fishpond; thedissolved oxygen probe is arranged in the lowest fishpond to detect the oxygen content in the fishpond, and is electrically connected to the PLC controller and transmits a detection signal to the PLCcontroller. According to the invention, the waterfall flow is formed in a manner of adoption of the variable frequency pump and water, and therefore, the mobility of water in the fishpond is increased and then the oxygen content is increased, not only is the water quality of water in the fishpond ensured, but also the fishpond is attractive.

Description

technical field [0001] The invention belongs to the technical field of fish farming equipment, and in particular relates to a stepped fish pond dissolved oxygen control system and a control method thereof. Background technique [0002] With the improvement of living standards, people pay more attention to spiritual needs. Tourism and leisure industries are booming. Generally, there will be fish ponds in scenic spots or temples to form a landscape. This kind of fish pond breeding is generally more expensive. For landscape fish, it is necessary to strictly control the living environment of the fish pond, especially the oxygen content in the fish pond. Many methods are directly oxygenated in the water. Poor, it is not good for the survival of landscape fish. Therefore, it is urgent to propose a fishpond dissolved oxygen control system and its control method. Contents of the invention [0003] Aiming at the state of the prior art, the present invention overcomes the above-me...
