METHOD OF AUTOMATIC CONTROL OF TEMPERATURE-LIGHT REGIME 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 of automatic control of light and temperature and humidity regime in greenhouses or other structures of protected ground. Automatic control system for light and temperature humidity regime in a greenhouse, which is carrying out the claimed method, contains a control circuit of temperature in a greenhouse, including a temperature sensor, whose output is connected with the object of regulation by the comparing element with a set point adjuster, signal multiplier of the current and the calculated temperature disagreement, as well as an actuating mechanism maintaining in the facility the calculated temperature, and the computer unit which calculates the optimum temperature. At that the system also provides additional control loops of lighting and humidity in a greenhouse.

EFFECT: invention enables to ensure the autonomy of temperature, air humidity adjustment inside the greenhouse and of operation of supplementary lighting equipment independently of each other, although at that their mutual influence on plant productivity remains.
