Kontrola mikro klime u plastenicima
Microclimate control in greenhouses
Sažetak
Osnovni cilj kontrole mikroklime u plastenicima je postizanje optimalnih uslova za rast i razvoj useva. Uzimajući u obzir složenost ovog procesa, prekomerna kotrlola mikroklime može nepovoljno uticati na razvoj useva. Šta više, potrebna nam je optimalna kontrola kako bi ostvarili ove ciljeve, uključujući niske troškove proizvodnje i nisku emisiju štetnih gasova. U ovom radu, opisan je jedan praktičan način za konstrukciju savremenog sistema u plasteniku. Sistem za kontrolu, pri regulaciji mikroklime, uzima u obzir vrednost unutrašnjih i spoljašnjih klimatskih parametara. Kontrolna jedinica očitava podatke sa senzora i u skladu sa zahtevanim klimatskim uslovima u plastenicima, sprovodi određenu akciju na izvršnim uređajima. Formiranje kontrolnog algoritma je u ovom slučaju složen proces, zbog međusobnog uticaja klimatskih promenljivih u plastenicima.
Abstract
The main reason for applying microclimate control in greenhouses is to achieve optimal growing environment. Because of its complexity, excessive control in greenhouses can adversely affect the growing crops. Moreover, we need an optimal ambiental control to accomplish these complicated objectives, including low emissions and reduced production costs. This paper describes one practical approach to the real-time control system in a greenhouse. Control system considers internal and external ambient factors related to the regulation process. Control system cyclically reads the data from the sensors and implements appropriate response on the actuator, based on required greenhouse conditions. Most challenging was the design of the control algorithm for this kind of process, due to a complexity of influential greenhouse variables.
