Abstract

The present invention discloses an intelligent aerator control system based on a two-stage filter circuit. The system is mainly formed by a central processor, a power supply, a display, a data memory, an analog to digital converter, an electromagnetic vibrating air pump, an oxide concentration sensor which is connected to the analog to digital converter, and a surge current limiting circuit connected between the central processor and the power supply in series, wherein the display, the data memory, the analog to digital converter and the electromagnetic vibrating air pump are connected to the central processor. The system is characterized in that: the two-stage filter circuit is connected to the analog to digital converter and the central processor and is formed by a first-order filter circuit and a second-order filter circuit which is connected to the first-order filter circuit. The intelligent aerator control system has strong controllability, the start and stop of an aerator can be automatically controlled, the oxygen production performance is stable, the oxygen production rate is high, the service life is long, and the resources can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of intelligent electronic equipment, in particular to an intelligent aerator control system based on a double-stage filter circuit. Background technique [0002] With the improvement of people's quality of life, more and more people like to buy a fish tank to raise small goldfish. Indoor use of fish tanks to raise small goldfish usually results in insufficient oxygen supply to the small goldfish. At present, the aeration machine is usually used to increase the oxygen in the fish tank, so as to create a good oxygen environment for the small goldfish. Insufficient oxygen supply or excessive oxygen supply will harm fish when using oxygen increasing machine to increase oxygen for fish tank. Therefore, when using oxygen increasing machine to increase oxygen for fish tank, it is necessary to ensure the stability and accuracy of the oxygen amount of fish tank. However, most of the existing aeration machines use a ...
