METHOD OF AUTOMATIC CONTROL OF TEMPERATURE AND LIGHT MODES IN GREENHOUSE AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2010 - IPC A01G9/26 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery, namely to methods and systems for automatic control of temperature and light modes in greenhouses or other structures of a protected ground. Automatic control system for temperature and light regime in greenhouse, implementing the claimed method, contains the control loop of temperature in a greenhouse, including a temperature sensor which output is connected with the object of regulation through the comparing element with the adjuster, a signal multiplier of maladjustment the current and the calculated temperatures, as well as an actuator supporting at the facility the calculated temperature, as well as the computing unit, which calculates an optimum temperature. Also the system contains an additional control loop of lighting.

EFFECT: invention enables to improve accuracy of maintaining temperature and lighting in cultivating area and stability of the system operation, as well as increase efficiency of photosynthesis mechanism in plants due to adjustment of such environmental factors as temperature and irradiance.
