基于PLC花卉种植温室小气候控制系统的设计

为实现对温室温的湿度和光照度等多项环境指数的智能化控制,有效地保障花卉的健康生长,针对花卉等植物在不同生长周期及单日不同时段对温室环境条件的要求,采用智能控制技术进行分季节控制模式的温室小气候控制系统设计。该系统控制核心由西门子S7-200SMART系列PLC和MCGS触摸屏组成,其能实时准确地采集温室温湿度和光照度等环境参数,上传至触摸屏进行分析、处理和集中化管理,并根据不同季节、生长周期及单日内不同时段自动调节温室环境,实现温室在多种模式下的自动控制,使温室环境保持在花卉的最佳生长条件范围内。

Design of the Micro-climate Control System in a Greenhouse for Flower Cultivation Based on PLC

The greenhouse micro-climate control system with the different season control patterns is designed by using the intelligent control technology according to demands of greenhouse environmental conditions to realize the intelligent control of some environmental indexes including temperature,humidity and light intensity in a greenhouse for healthy growth of flowers.The control core of the system is composed of PLC and MCGS touch screen of Siemens S7-200 SMART,which can collect the environmental parameters of temperature,humidity and light intensity in a greenhouse,transfer these data to the touch screen for analysis,processing and centralized management,automatically adjust the greenhouse environment according to different season,growth period and different time period in a day for realizing automatic control in a greenhouse under various modes and maintain the optimum conditions for flower growth in a greenhouse.
