Solar automatic aeration system and control method thereof

The invention relates to a system for aerating water body, in particular to a solar automatic aeration system and a control method thereof. The solar automatic aeration system charges a storage battery by using solar energy and the combination of a solar photovoltaic component, the storage battery, a control device, the aeration device and an oxygen content testing device, and supplies power to an aeration device to realize aeration. The control method is used in the control device for processing the signal of oxygen content in the water body detected by the oxygen content testing device, comparing the processed signal with an initial value set in a single-chip of the control device and then immediately sending a signal for aeration or stopping aeration. The system and the method have the advantages of solar power generation with renewable resources, energy saving, environment protection, labour saving, labour cost saving and timely control over oxygen content of water environment.
