中文摘要:针对目前温室植物补光无法针对植物生长状况实时反馈控制的问题,以LED补光系统为基础,设计了基于FluorMonitor叶绿素荧光传感器的植物补光测控系统。通过SDI-12和MODBUS通信协议实现对叶绿素荧光参数和光温参数的采集;并根据叶绿素荧光参数Ft、Fm、光化学量子效率Yield的测量流程和采集周期,设计了自动采集模式和手动采集模式;通过PWM调光模块的设计,完成对LED发光强度的精确调控;通过设计人机接口,实现了对光温参数和叶绿素荧光参数的显示和人机交互操作。以生菜为研究对象,进行了不同调光方式的补光调控试验,试验结果表明,基于叶绿素荧光的LED补光控制系统可以实现对光强、ETR和Yield的稳定控制,增加生菜对光能的利用效率,实现了基于作物生理信息的反馈控制。

Abstract:In order to realize real time feedback control for plant supplementary lighting based on the plant growth status, the LED lighting control system based on the FluorMonitor chlorophyll fluorescence sensor was designed. By the SDI-12 and MODBUS communication protocols, the parameters of chlorophyll fluorescence, light intensity and temperature acquisition were realized. According to the measurement process and acquisition cycle of chlorophyll fluorescence parameters of Ft, Fm and Yield, the automatic acquisition mode and manual acquisition mode were designed. Using the pulse width modulation (PWM) control mode, the LED light intensity control model was designed to realize the plant lighting accuracy control, and the display of light, temperature and chlorophyll fluorescence parameters and human computer interaction were realized through the design of man machine interface. The supplementary lighting control experiment for lettuce was carried out. The results showed that the LED lighting control system based on chlorophyll fluorescence sensor can realize the stable control of light intensity, ETR and Yield. The system can improve the light utilization efficiency of lettuce, and the lighting real time feedback control based on plant growth status was realized.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
