Design and application of intelligent control system for greenhouse environment

An intelligent greenhouse control system based on the (programmable logic controller) PLC and Kingview has been designed to meet the needs of crops greenhouse. Aiming at the problem of the greenhouse control system that is difficult to achieve a precise control performance, this paper focuses on the fuzzy logic algorithm to achieve an accurate prediction control. The Mitsubishi PLC is applied as the lower computer to fulfill real-time data collection and automation function in a greenhouse scenario. The configuration software set KingView 7.5 is employed as the upper computer to provide a friendly control interface and accomplish remote monitoring and control task, combining with the fuzzy logic algorithm, an intelligent greenhouse control system is established. Experimental results demonstrate that a better adjustable condition for crops can be achieved for the proposed greenhouse system. It also proves that the designed greenhouse intelligent control system has the characteristics of stable performance, convenience and versatility, etc., and the proposed scheme is worthwhile to be applied in the future.
