Judge module 101 can be strength of fluid optical detecting sensor or IMAQ and treatment unit.The growth conditions of diatom can embody with the biomass of diatom, or embodies by the organic concentration in the water body of cultivation diatom.
The growth phase of diatom roughly can divide three phases: vegetative period, peak period and aging time, and in vegetative period, the biomass of diatom is less, and in some dulling of water of cultivation diatom, water body, organic (organic matter can be secondary metabolite) concentration is high; In peak period, the biomass of diatom can sharply rise many, and diatom occurs in a large number, because diatom quantity is more, so frond is orange-yellow or tawny, and diatom to consume organism speed fast, so organic concentration is lower; At aging time, diatom integral body is in succession of the old by the new period, overall activity a little less than, now organic concentration is minimum, the collagen on frond surface or cellulosic protective capability also decline greatly, so being a bit darkish in color of water body no longer manifests vivid green.
Above-mentioned the growth phase of diatom has roughly been divided to three phases, in the embodiment of the present invention, the growth phase of diatom is not limited to three phases, the growth phase of different classes of diatom can be different, growth phase such as diatom can be divided into the double teachers such as lag phase, exponential phase of growth, allometry decrement phase, stationary phase and decline phase, wherein, the secondary metabolite in each stage as the content of chrysolaminaran and grease and composition different, and each stage have corresponding number of days.
From the foregoing at different growth phases, the biomass of diatom is different, the water body color of diatom is different, some organic concentration is different, so can judge by some organic concentration in the water body of strength of fluid optical detecting sensor detection cultivation diatom the current growth conditions of diatom.Also can to cultivating the water body of diatom, take, and the image of taking is processed by IMAQ and treatment unit, according to the color of water body, obtain the current biomass of diatom, thereby learn the current growth conditions of diatom.
Because each growth phase of diatom has the corresponding time, for example, be the tenth day of lunar month sky of growth of diatom algae vegetative period, peak period is the centre ten days of growth of diatom algae, aging time is last ten days of growth of diatom algae, so judge module 101 can also be timing module, growth characteristics parameter comprises time interval, growth characteristics parameter is corresponding with this time interval, and now the growth conditions of diatom refers to the time of judge module 101 records.
Obtain dutycycle module 102, for obtain corresponding growth characteristics parameter according to current growth conditions, and draw according to this growth characteristics parameter royal purple light dutycycle and ruddiness dutycycle corresponding to ruddiness that the required royal purple light of diatom is corresponding.
