[Abstract]:Photosynthesis is an important way for green plants to get energy. Chlorophyll fluorescence can be used as a probe for plant photosynthesis, and a set of chlorophyll fluorescence online detection system is designed. The MINI-PAM fluorescence spectrometer can be detected in real time to plant chlorophyll fluorescence parameters, and through the LED light source radiation plant makes plants grow in different light conditions, measured the fluorescence parameters of the plant under different conditions and the rapid light response curve, as the effects of different environmental factors, research on plant photosynthesis and therefore designed a intelligent detection and control system to realize the detection of chlorophyll fluorescence parameters of plants. In this paper, the background, purpose and significance of the research on the design of chlorophyll fluorescence parameter detection system are introduced. The methods and inadequacies of the detection of chlorophyll fluorescence parameters at home and abroad are introduced. By designing a set of intelligent detection and control system to detect the chlorophyll fluorescence parameters, in the part of the hardware design of detection system, first introduced the detection system design, through the design of hardware principle diagram of detection module, environmental factors, sensor and the main chip selection, hardware design principle of liquid crystal display module and keyboard input module and design the Zigbee module hardware principle diagram, completed the hardware design principle of detection system of chlorophyll fluorescence parameters. Through the design of the hardware schematic of each part, the construction of the basic framework of the chlorophyll fluorescence parameter detection system is completed. The next part introduces the software design of detection system of chlorophyll fluorescence parameters, through the software design of detection system of the parameters of chlorophyll fluorescence detection, on the basis of the hardware design can be achieved on the environmental factor detection system of chlorophyll fluorescence parameters and chlorophyll fluorescence detection parameters, the control part adopts fuzzy control algorithm based on fuzzy design controller, fuzzy processing of input and output of the fuzzy rules, the completion of the design and implementation of fuzzy control system, finally, through the Matlab simulation module of Simulink simulation software, the fuzzy control system simulation, by observing the input of a step signal, observe the response ability of simulation system the stability judgment system. Finally, through the data acquisition system to detect environmental factors of chlorophyll fluorescence parameters of the host computer system, performance detection system to maintain the temperature, humidity and C02 concentration of environmental factors in size is relatively constant, by changing the programmable current source size changing plant environment light intensity, influence on chlorophyll fluorescence parameters in different light the strength of plants with light intensity are different. Through the design of chlorophyll fluorescence parameter detection system, we can realize the automatic monitoring, control, storage and display of environmental factors of chlorophyll fluorescence parameter detection system. At the same time, it can provide historical records and data of various environmental factors. The operation of the test results shows that the intelligent monitoring system is stable, accurate and reliable, and can meet the control requirements. It has a good application prospect in the study of plant photosynthesis.
