METHOD FOR AUTOMATIC CONTROL OF LIGHT-TEMPERATURE REGIME IN THE GREENHOUSE AND SYSTEM FOR ITS IMPLEMENTATION

摘要

1. A method for automatically controlling the light-temperature regime in a greenhouse, including dividing the vegetative period of plants into equal time intervals, the duration of which is an order of magnitude shorter than the time constant of the fastest disturbance, measuring for each time interval air humidity, air temperature and illumination in the greenhouse with receiving signals from air humidity, temperature and light sensors, respectively, measuring the age of plants with receiving a signal from a counter of age of races a meter and a counter that measures the duration of a given photoperiod, and this data is sent to a computer controller that calculates the average value of the night temperature, and then calculates and sets the optimal light-temperature parameters of the air inside the greenhouse, such as a multidimensional temperature and one-dimensional day temperature that is optimal according to the productivity criterion and keeps one of them constant depending on the prevailing conditions over the entire period of time, as well as optimal productivity criterion This multidimensional illumination and one-dimensional illumination and supports one of them with the help of illumination equipment included in the photoperiod set by the agricultural technician, characterized in that the total daily radiation during the day, obtained from solar radiation and from a moving light spot organized by mobile irradiators, is measured by a counter counter , compare it with the calculated computer set-up and provide multidimensional optimal total radiation, determined by the illuminating equipment, determined about
