摘要

针对现有植物工厂采用的植物培养架照度、混色均匀度差导致农产品作物品质参差不齐的现状，提出一种高混光、高混色均匀度的植物培养架设计方案。不同于光源在上种植面在下的培养架设计模式，将红、蓝LED灯珠间隔排列阵列光源安装在植物种植平面上的凸台上，并把培养架顶部设计成漫反射面。漫反射面的引入起到增加混光距离的作用，提高光线耦合程度，从而达到了提高混光、混色均匀度的效果。进一步引入光量子通量密度均匀度以及混色均匀度共同作为考察指标，利用Taguchi方法设计并进行实验，研究不同因子对植物种植区光源均匀性的影响，再利用ANOVA理论分析了各因子对品质的影响程度多次优化后，最终获得照度均匀度为94.58%、混色均匀度为90%、能量利用率为41.42%的最优系统设计方案。然后研究了不同配光曲线的灯珠对培养架均匀度的影响，最后通过测量植物在不同高度时种植面和植物表面的照度及光谱的分布情况检测植物的生长是否会遮挡光线。结果表明该植物照明系统可以在植物生长过程中提供均匀的照明，遮挡问题几乎可以忽略不计。

Abstract

Aiming at the present situation of the uneven agricultural product quality which is caused by the poor illuminance uniformity and the poor mixed color uniformity in plant growing shelf adopted by existing plant factory plant cultivation

we put forward a kind of design scheme of plant growing shelf with high light mixed evenness and high color mixed uniformity. Different from the design scheme whose light source is above the planting plane

red and blue LEDs were arranged at regular intervasl installed in the boss club of planting plane

and a diffuse surface was designed on the top of the plant growing shelf. The import of the reflection surface plays the role of increasing mixed light distance

improves the ray coupling degree

so as to achieve high light mixed uniformity and high color mixed uniformity. Photosynthetic photon flux density uniformity and color mixed uniformity were further introduced as examining index. The Taguchi method was used to design and conduct experimental exploration to study the influence of different levels of factors on the uniformity of light source in plant planting area

and ANOVA theory was used to analyze the influence degree of each factor on the quality. After multiple optimizations

we finally obtained the best system design scheme whose intensity of illumination uniformity is 94.58%

the color mixed uniformity is 90% and the energy utilization rate is 41.42%. Then

the effects of different light distribution curves on the uniformity of the culture frame were studied. Finally

by measuring the illuminance and spectral distribution of the plant surface at different heights

it is detected whether the growth of the plant will block the light. The results show that the plant lighting system can provide uniform illumination during the growth of the plant

and the occlusion problem is almost negligible.
