The invention provides a greenhouse environment control method and system and a greenhouse, and belongs to the technical field of greenhouse planting.The method comprises the steps that the outdoor temperature and the indoor temperature are obtained; and when it is determined that any one of the outdoor temperature and the indoor temperature is larger than the target temperature and the other one is smaller than the target temperature, the ventilation opening is opened, indoor and outdoor heat exchange is achieved, and the indoor temperature tends to the target temperature. And when it is determined that the outdoor temperature and the indoor temperature are both smaller than or larger than the target temperature, the ventilation opening is closed to prevent indoor and outdoor heat exchange, and the indoor temperature is not affected by the outdoor temperature. Through the control method, the indoor temperature is always in a better temperature range.
Description
technical field [0001] The invention relates to the technical field of greenhouse planting, in particular to a greenhouse environment control method, system and greenhouse. Background technique [0002] The cultivation of crops in the greenhouse is less affected by external weather changes, which can ensure the growth of plants in different seasons, but it is difficult for economical solar greenhouses to ensure that the internal temperature is always controlled within the optimum growth temperature range of plants. Therefore, it is an urgent technical problem for those skilled in the art to provide a greenhouse environment control method, system and greenhouse that can solve the above problems at least to a certain extent. Contents of the invention [0003] The present invention provides a greenhouse environment control method, system and greenhouse capable of solving the above problems at least to a certain extent. [0004] A kind of greenhouse environment control method...
