Abstract

Kroz ovaj rad, prikazano je softversko i hardversko rješenje automatizacije zaštićenoga prostora, konkretno plastenika za uzgoj biljaka. U uvodu je iznesen značaj i uloga zaštićenoga prostora te različiti mogući načini automatizacije istoga. Zatim se iznose i opisuju potrebne komponente automatiziranog sustava, te njihov značaj za biljke. Naglasak je na programibilnom logičkom kontroleru i senzorima čiji je rad detaljnije opisan. Za opisane komponente predložen je popis uređaja i senzora dostupnih na tržištu pa je za iste izrađen troškovnik. Također se prikazuje primjer rasporeda i shema spajanja uređaja na skici plastenika. S time se prelazi na upravljački kod, gdje se najprije ukratko opisuju korišteni softveri. Nadalje se detaljno opisuje cijeli upravljački kod i dizajn korisničkoga sučelja. Nakon toga se opisuje laboratorijski postav na kojemu je izvršena simulacije, te se prikazuju rezultati simulacije. Naposljetku iznosi se zaključak cijeloga rada i moguća poboljšanja u sustavu.

Abstract (english)

This paper has presented the software and hardware solution for the automation of a growhouse. In introduction, the importance and function of growhouse and various ways of automating one is presented. It is followed by the description of the required components of automated system, and their imporatance for plants. Accent is on programmable logic controller and sensors whose operating principles are described in detail. For described components a list of commercially available devices and sensors is proposed, and a cost estimate has been made. Moreover, an example of the layout and the device connection scheme is outlined on the dimensional drawing of the considered greenhouse. In the second part of this work, the development of the control program is presented, starting with the software environment used for programming, followed by the actual control code development and the design of the graphical user interface (GUI). This is followed by the description of the laboratory setup which is used for process control simulation, which has been used for actual process simulation within the proposed control framework. Final chapter gives the concluding remarks and possible improvements of systems.
