The intelligent oxygenation system uses the power carrier mode mode to form a local area network. The dissolved oxygen sensor of the fluorescence method is used to measure dissolved oxygen in the water body, and the dissolved oxygen signal is sent to the intelligent control board in the automatic cleaning device, which is linked with the frequency conversion board to adjust the running speed of the permanent magnet synchronous motor, thus achieving the purpose of scientifically adjusting the oxygenation power according to the dissolved oxygen value in the water body. The relevant data is transmitted to the cloud platform through 4G communication. Realize mobile phones, computers and other terminal monitoring, control and other operations, offline state can also run automatically.
