摘　　要：设计了一种大棚内植物紫外(UV-B)照射智能控制系统,并研究了设备在棚内的照度分布.系统分为硬件和软件部分,其工作包括了单机和联机模式(均有恒定和室外同步UV-B两种控制模式).硬件系统以单片机为控制核心,采用TCL1345进行模数转换,通过905将数据发送给电脑进行处理;软件控制界面主要由操控部分,数据显示部分和其他设置构成.系统的受照面照度分布为一系列近似于椭圆的同心等照度区域.随高度的减小,照度值增大,中心等照度区域面积也增大,但相邻等照度带之间的照度差值也越大,即整体均匀程度降低.An intelligent control system of plant ultraviolet （UV-B） irradiation inside the greenhouse was designed, and distribution of the equipment＇s inside illumination was studied. The system included hardware part and software part, its working mode including stand-alone mode and online mode （ both of them included constant mode and out- door synchronous UV-B mode）. SCM was the key of the hardware system. TCL1345 was used to finish analog-to- digital conversion. The data was send to the computer for processing by 905. The control interface of the software included control, display and other parts. Distribution of the system＇s illumination was like ellipse. With the de- creasing of the height, the value of the illumination would increase and the area of the same illumination would in- crease, but the difference of the same illumination area would increase and the uniformity would decrease.
