摘要
光合有效辐射传感器可测量可见光波段400nm^700nm的光量子流密度,不能准确区分LED组合光源的各种光质比例,已无法满足光生物学研究和植物工厂生产的实际需要。本文提出一种多通道光合有效辐射传感器,通过模拟植物窄带光谱响应的传感器同时测量红光、蓝光光量子流密度,其成本低、便携,适用于应用LED补光的光伏农业大棚和植物工厂应用。大量传感器组网,可以采集植物生长的光配方数据和实现光照智能控制、对规模化的植物工厂光质需求数据积累与降低能耗意义重大。
Photosynthetic active radiation sensors only response to the light between 400 nm ~ 700 nm. The red light quantum and blue light quantum cannot be identified directly for LED light. In this paper,a multichannel photosynthetic active radiation sensor which has a narrow-band spectral response matching with plant absorption peak is proposed. The red light and the blue light are measured with quantum density directly. It can be applied to plant factory with low cost and portable. It is also easy to create sensor network,collect the plant growth light recipe data and realize intelligent control of light. This sensor can play a key role on the plant light recipe accumulation and the energy consumption reduction for plant factory.
