METHOD OF AUTOMATIC TEMPERATURE CONTROL IN GREENHOUSE Russian patent published in 2010 - IPC A01G9/26 

FIELD: agriculture.

SUBSTANCE: greenhouse plant cultivation period is broken down into several time intervals, the required rate of plant development and the adequate daily average temperature are specified. Each time interval is described by the light conditions: day or night. If the system has identified a daytime, then illumination, indoor air humidity, age of plants, photoperiod duration and relative daytime are measured. The average last-night temperature is calculated to derive the optimum producing temperature. If the system has identified a night-time, the average last-day temperature and the night temperature are determined. The estimated optimum producing temperature and night temperatures are corrected with observing the acceptable values.

EFFECT: higher accuracy of the fructification start time planning on the one hand and from the other hand, well developed and strong plants by the moment by photosynthesis intensification.
