作物光照智能调控技术研究

Study of Light Intelligent Control Technology

为了解决现有作物光照控制系统不可调、易造成能源浪费或补光不足的问题,根据作物光合速率公式,分析作物生长环境温度、CO2浓度与自然光照对作物生长需求的影响,推导建立基于自适应性原理的作物补光数学模型。以此数学模型为原则,采用PLC为控制核心,以Zig Bee技术进行无线传输,完成光照系统的软硬件设计。调控结果表明:该系统不仅可以完成作物自适应性补光智能控制,而且可以在最大限度满足作物生长需要的同时,尽量避免光照能源的浪费。

The existing crop light supplement system has some deficiencies such as energy waste. Based on crop photo- synthetic rate formula, the influences of temperature, CO2 concentration and natural light on crop growth are analyzed. And the mathematical model of crops light based on adaptive principle is derived. According to the model, the supplement system uses PLC as the control core and Zigbee for wireless transmission to complete the software and hardware of supple- mental lighting system. The control results demonstrates that it not only can complete the intelligent control system of crop light based on adaptive principle, but also can avoid the lighting energy waste while satisfy the maximum light requirement of crop growth.
