Portable intelligent plant physiological state detection system and method

Abstract

The invention discloses a portable intelligent plant physiological state detection system and method. The portable intelligent plant physiological state detection system comprises a lighting module and a camera unit used for collecting fluorescent images of a to-be-detected plant, the lighting module comprises an LED array providing excitation light for lighting and an optical thin film arranged on a light emitting side of the LED array, reflectivity, to fluorescent light of the to-be-detected plant, of the optical thin film is smaller than 5%, and reflectivity, to LED light, of the optical thin film is larger than 95%. By the portable intelligent plant physiological state detection system and method, a user can perform chlorophyll fluorescence detection on plants in field conditions in a portable manner, the fluorescent images acquired by measuring can be processed and analyzed in realtime, a measuring result can be matched with plant physiological states in a database of a remote cloud sharing server in realtime, and updating and machine learning of new samples of the database can be realized.

Description

technical field [0001] The invention relates to the field of chlorophyll fluorescence detection, in particular to a method and system device capable of carrying out plant chlorophyll fluorescence detection under field conditions and realizing intelligent real-time data analysis. Background technique [0002] Photosynthesis is one of the most important chemical reactions on the earth. It uses sunlight to split water to release most of the oxygen needed on the earth, and at the same time fixes carbon dioxide in the atmosphere to provide glucose for metabolism. In the light reaction process of photosynthesis, the absorbed light energy is transferred. In the process of converting into electrical energy, part of the light energy loss is released in the form of longer-wavelength fluorescence. Under natural conditions, chlorophyll fluorescence has a very close relationship with photosynthesis. Many changes in the photosynthesis process can be reflected by chlorophyll fluorescence....

Problems solved by technology

However, because the uniform illumination area is limited to a specific illumination distance, the uniformity of the excitation light becomes worse after leaving this distance, and due to the divergence characteristics of the light source, the excitation light intensity becomes weaker after the distance increases, which cannot meet the measurement requirements

For the whole plant, due to the different heights of different leaves, it is impossible to measure these leaves at the same time
