Embodiment three
See also Fig. 4, the structural representation of a kind of intelligent light irradiation apparatus of cultivating for blue-green algae that provides for the utility model embodiment, this intellectuality light irradiation apparatus comprises: memory module 100, parameter acquisition unit 401, judge module 101, trigger module 402, obtain dutycycle module 102, light source module 103, illumination control module 403, wherein:
Obtain dutycycle module 102 and link to each other with memory module 100, parameter acquisition unit 401, light source module 103, illumination control module, judge module 101 and trigger module 402 respectively, illumination control module 403 links to each other with light source module 103.
The blue algae growth parameter comprises: growth characteristics parameter and blue green light dutycycle and the ruddiness dutycycle corresponding with the growth characteristics parameter.The growth characteristics parameter comprises that biomass is interval.
The parameter of outside input comprises the classification of blue-green algae.
The classification of blue-green algae can comprise the kind of blue-green algae and/or the kind of blue-green algae.
The kind of blue-green algae comprises: basketball algae (chroococcoid), nostoc (delivering vegetables), the algae that quivers, Microcystis aeruginosa, anabena, spirulina, plan Anabaena, chamber ball algae, tip algae, broken face algae, glue sheath algae, joint ball algae and Shu Maozao etc.
Other blue-green algae of same class also has different kind (comprising such as spirulina: spirulina plalensis, spirulina maxim and salt pool spirulina), the blue-green algae of same classification different varieties may be different in the needed illumination of same growth conditions (light quality, light intensity and light dark period).
The growth conditions of blue-green algae comprises the biomass of blue-green algae.
The function of parameter acquisition unit 401 and judge module 101 can or be part of functions in the micro-control unit (MCU) for micro-chip, and parameter acquisition unit 401 and judge module 101 can or be a part in the micro-control unit (MCU) for micro-chip.
When the biomass of blue-green algae falls into current biomass interval, illustrate as long as light source module 103 is kept current illumination, do not need to change, obtain dutycycle module 102 so need not trigger.
Concrete, trigger module 402 can be triggering device.
Obtain dutycycle module 102, be used for obtaining corresponding growth characteristics parameter according to the classification of current biomass and blue-green algae, and draw blue green light dutycycle corresponding to blue green light and ruddiness dutycycle corresponding to ruddiness according to the growth characteristics parameter;
Because the blue-green algae classification is a lot, different classes of blue-green algae is different in the intensity of illumination threshold value of the required blue green light of same biomass and ruddiness, so need the classification by parameter acquisition unit 401 collection blue-green algaes.If only need cultivate other blue-green algae of same class, so can there be parameter acquisition unit 401 yet, obtain dutycycle module 102 this moment, be used for judging that biomass corresponding to described current biomass is interval, and obtain the dutycycle module according to what the biomass interval drew ruddiness dutycycle corresponding to blue green light dutycycle corresponding to blue green light and ruddiness.
General, little algae is in different growth phases, the dutycycle of pwm signal need to change, corresponding light wavelength (light quality) also can change, be that the intensity of illumination threshold value changes, but in the light dark period of same blue-green algae, light quality and light intensity generally can not change, and namely the ratio of different wave length and intensity of illumination threshold value are constant.The growth characteristics parameter of blue-green algae can also comprise: with the intensity of illumination threshold value of the intensity of illumination threshold value of the interval corresponding blue green light of biomass and ruddiness, with blue green light drive current corresponding to the intensity of illumination threshold value of the intensity of illumination threshold value of described blue green light and ruddiness and ruddiness drive current and with blue green light dutycycle corresponding to described blue green light drive current and the ruddiness dutycycle corresponding with described ruddiness drive current.Accordingly, can store in the memory module 100 biomass interval with blue green light the intensity of illumination threshold value and the relation curve of the intensity of illumination threshold value of ruddiness, the relation curve of the intensity of illumination threshold value of blue green light and the intensity of illumination threshold value of ruddiness and blue green light drive current and ruddiness drive current, the relation curve of blue green light drive current and ruddiness drive current and blue green light dutycycle and ruddiness dutycycle, corresponding relation between parameters can obtain by corresponding curve, certainly also can directly store the corresponding relation of parameters in the memory module 100.
In above-described embodiment, increase along with blue alga biomass, the working current of light source module 103 strengthens thereupon, this moment, the photon overall consistency of the light that light source module 103 sends increased, and in the process that the photon overall consistency increases, the 3rd glow peak intensity of illumination threshold value amplification degree is less in the spectrum, and the intensity of illumination threshold value increasing degree of the first glow peak and the second glow peak is larger, and ratio strengthens in total intensity of illumination threshold value.The intensity of illumination threshold value of the light that light source module 103 sends is larger, the drive current that needs is just larger, while is based on the proportional relation of dutycycle and drive current, make and obtain the corresponding dutycycle of dutycycle module 102 outputs, the dutycycle of the larger correspondence of required drive current is higher, wherein, dutycycle changes between 0%-100%, and namely light source module 103 can be as required changes between maximum exportable light intensity at zero-sum in the intensity of illumination threshold value of the first glow peak to the four glow peaks.
