[0041] As the sun rises and solar radiation increases, but before reaching the conditions for the solar thermal collector system to operate independently, the solar heating system and the biomass heating system operate in combination. As solar radiation continues to increase and reaches the conditions for the solar thermal collector system to operate independently, the solar thermal collector system operates independently. Cloudy Conditions: When there is no solar radiation, the control and management platform 2 predicts in advance the heat output of biomass boiler 4. If the heat output of biomass boiler 4 is less than the heat required by the room, the biomass heating system and the wind power heating system will operate in conjunction. During the day, as the sun rises and solar radiation increases, the control and management platform 2 predicts in advance the heat output of solar collector 37 and biomass boiler 4. If the heat output of the solar collector system is less than the heat required by the energy-efficient building 17, and solar radiation continues to increase but the conditions for the collector system to operate alone during the day are never met, the solar heating system and the biomass heating system will operate in conjunction.
[0042] Cloudy day condition: There is no solar radiation, the solar collector 37 is in a stopped state, the control and management platform 2 predicts in advance that the heat output of the boiler is less than the heat required by the energy-saving building 17, and at this time the biomass energy heating system and the wind power generation heating system operate together for heating.
