【摘要】：光照對植物、菌類等生物的生長起著至關(guān)重要的作用,對作物干物質(zhì)形成與積累、作物抗凍性等特性存在較大的影響。由于不同波段對菌類的生長效果存在差異,傳統(tǒng)單波段定量閾值調(diào)控對菌類的生長無法實現(xiàn)最優(yōu)效益,人工精準(zhǔn)調(diào)光技術(shù)可有效改善菌類的生長光環(huán)境,實現(xiàn)菌類高效優(yōu)質(zhì)栽培和規(guī)模化優(yōu)化生產(chǎn)。針對上述問題,本文設(shè)計一種基于LED的菌類光響應(yīng)測試系統(tǒng),系統(tǒng)由主控設(shè)備、LED驅(qū)動設(shè)備、光照檢測設(shè)備組成,光照檢測模塊實現(xiàn)特定波段光照信息采集,主控設(shè)備實現(xiàn)對光照強度信息接收處理和LED驅(qū)動設(shè)備的按需控制,LED驅(qū)動設(shè)備實現(xiàn)微處理器至LED光源的控制信號放大與亮度控制,以期為探明食用菌光響應(yīng)特性提供基礎(chǔ)測試平臺。本文主要完成的工作與結(jié)論如下:(1)為實現(xiàn)高效光環(huán)境調(diào)控,依據(jù)菌類所需設(shè)計光源強度可調(diào)的補光設(shè)備。通過選用LED驅(qū)動芯片,實現(xiàn)對控制信息放大;LED燈組排列串、并交錯,實現(xiàn)菌類生長環(huán)境的光強均勻分布;不同菌類所需光質(zhì)存在差異,相同菌類不同生長期下需光量也具有差別,設(shè)計紅、黃、藍、綠四種LED燈組作為補光燈;由于四種LED光源電氣參數(shù)存在差異,設(shè)計四種不同驅(qū)動能力的LED驅(qū)動模塊。(2)根據(jù)菌類光環(huán)境差異性需求,研發(fā)菌類特定波段光照度檢測設(shè)備,實現(xiàn)對不同波段光源強度的定量檢測。選用光照度傳感器作為檢測四種類指定波段光源強度的傳感器,在光照度傳感器表面貼附四種顏色的濾光片,實現(xiàn)特定波段光質(zhì)的檢測;四種類光源檢測除濾光片不同之外,其余電氣參數(shù)設(shè)置均相同。(3)通過在培養(yǎng)室內(nèi)實地部署菌類光響應(yīng)測試系統(tǒng),開展系統(tǒng)有效性與節(jié)能試驗驗證。試驗結(jié)果表明,系統(tǒng)可以長期部署于菌類栽培環(huán)境內(nèi),實現(xiàn)設(shè)施不同波段光照的按需調(diào)控。
[Abstract]:Light plays a vital role in the growth of plants and fungi, and has a great influence on the characteristics of crop dry matter formation and accumulation, and the frost resistance of crops. Due to the difference in the growth effect of different bands on the growth of fungi, the traditional single band quantitative threshold regulation can not achieve the optimal benefit for the growth of the fungus. Technology can effectively improve the growth light environment of bacteria, achieve high efficiency and quality cultivation and scale optimization of production. Aiming at the above problems, this paper designs an optical response test system based on LED, the system consists of main control equipment, LED drive equipment, light detection equipment, illumination detection module to realize the specific band light information collection, main. The control equipment realizes the reception processing of light intensity information and the on-demand control of the LED driving device. The LED drive device realizes the control signal amplification and the brightness control of the microprocessor to the LED light source, in order to provide the basic test platform for the detection of the light response characteristic of the edible fungi. The main work and conclusion of this paper are as follows: (1) in order to achieve the high efficiency of the light environment Control, according to the need to design the light intensity adjustable equipment of light source, LED drive chip is selected to enlarge the control information; the LED lamp group is arranged and interlaced to realize the uniform distribution of the light intensity of the fungus growth environment; the light quality of the different fungi is different, the light quantity of the same fungus in different growth period is also different, and the design red is also designed. Four kinds of LED lamp groups of yellow, blue and green are used as light lights. Because of the differences in electrical parameters of the four kinds of LED light sources, four kinds of LED driving modules with different driving abilities are designed. (2) according to the difference demand of the light environment of the fungus, the light illumination detection equipment of the specific band of the fungus is developed to realize the quantitative detection of the intensity of the light source in different bands. In order to detect four kinds of sensor with specified band light intensity, four kinds of filters are attached to the light sensor surface to detect the light quality in a specific band. The other electrical parameters are the same for the four kinds of light sources, except for the filter. (3) by deploying the light response test system in the cultured room, the system is carried out. The system effectiveness and energy saving test proved that the system can be deployed in the bacterial culture environment for a long time and realize the regulation of the light in different wavelengths of the facility.
