LED植物补光源光量子通量密度的数据采集系统
Design of Photo Flux Density Data Collection System for LED Plant Lighting
摘要
Abstract
Urban agriculture, such as LED plant factory, based its research and development on the measurement of luminous environment for plants growth. Plant mainly absorbs red and blue light to grow, therefore,LED plant factories and research institutions use monochrome LED lights for plant supplemental lighting. The PAR quantum sensors, which could measure the photon flux of radiation in the spectral interval 400~700 nm, can't measure photon flux of red and blue LED simultaneously. This blocks the further research on real time measurements and system feedback control. Therefore, this paper presents a data acquisition system for measuring the amount of red and blue light in the LED light sourcerespectively, to solve the above problems. This paper describes the LED light quantum data acquisition system, the overall structure and the hardware design of each part and the host computer design. And the system monitors the red and blue light quantum number in real time, and then compares the data with the actual value. The results show that the measured data in the system is within the error tolerance range.关键词
