Example 2:
example 2 is the same as example 1 except that:
After sunrise in the morning, the solar radiation intensity is gradually increased, the output of the solar panels 14 is increased, and when the output power required by the inverter task is reached, the inverter is started to operate actively.

The stronger the sunlight intensity is, the higher the temperature in the granary 1 can rise, and meanwhile, the stronger the sunlight intensity is, the more electric energy generated by the solar panel 14 is, so that the circulation grain cooling machine 7 can work in a high-power state, the better the cooling effect of the circulation grain cooling machine 7 is, the temperature rise caused by sunlight in the granary 1 can be just made up, and the temperature in the granary 1 is always kept in a lower state.
Example 5:
example 5 is the same as example 4 except that:
