At present relative to water system process, nutrition bait, seedling-raising technique and disease control research, the influence research of China to the illumination of fish physiological function is relatively less and extensive.The spectrum intensity photoperiod demand that LED light source and intelligent control system can grow needed for gonad development according to fish species regulates, and the growth for marketable fish provides rational luminous environment condition, can significantly improve the yield and quality of fish; In order to reduce the incidence of circulating water cultivation factory Atlantic salmon sufferer and death and increase bait utilization as much as possible, now both at home and abroad increasing scholar begins one's study various illumination solution.
In addition, unexpected open and close lighting can make fish produce light and coerce emergency reaction, increases the death rate.Address this problem the Based Intelligent Control that can adopt LED, the process of open and close is completed in mode that is bright, that go out gradually (3-5 has divided) gradually, thus reduces the death rate of fish.
In sum, the artificial light source used in closed circulation clean water cultivation field mainly contains high-pressure sodium lamp, fluorescent lamp etc., the problems such as the outstanding shortcoming of these light sources is light efficiencies, classification of waterproof is low, energy consumption is large, operating cost is high, the light quality photoperiod can not regulate and control.In addition, the discarded meeting severe contamination water source of fluorescent lamp, the fluorescent tube of an electricity-saving lamp is on average containing the mercury of 0.5 milligram, to of low pollution 180 tons of water after fragmentation, because the boiling point of mercury is low, can evaporate under normal temperature, broken power saving fluorescent lamps, moment can make the mercury concentration over-standard hundreds of times in the humid air of workshop.Traditional gas charging source has been not suitable with environmental protection, energy-saving and emission-reduction and has optimized the requirement of optical parameter.So, for the weak point that existing fish Lighting Control Assembly exists, need to improve all sidedly on prior art basis.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming above-mentioned existing conventional light source existence, a kind of LED light source control system for crawl is provided, effectively can improve Atlantic salmon marketable fish output, increase economic efficiency, realize the object that volume increase reduces discharging with source.
For this reason, the invention provides a kind of LED light source control system being applied to crawl, it is characterized in that, comprise: light source controller, multiple LED projector lamp, computer, wherein, each LED projector lamp is made up of the LED chip of short wavelength, light source controller comprises microprocessor, the clock unit be connected with microprocessor and serial communication interface unit, microprocessor cultivates for storing in crawl the parameter that sashimi (raw fish) is long and grow, and the light intensity of LED projector lamp is regulated according to described parameter, computer is used for arranging the parameter stored in microprocessor.
For cultivation fish in the demand of Different growth phases to different light medium, different growth curve regulating parameter is set, parameter is stored in the internal storage E2PROM of microprocessor, after every subparameter stores, just computer can be withdrawn from the present invention (parameter is consistent in same growth phase, does not need to arrange again).Software model in microprocessor reads stored parameter from internal storage E2PROM, runs this software model, for control that is bright to lamp, that go out, thus realizes the adjustment to LED light intensity.
The present invention has following beneficial effect: from the utilance and photochromic and photoperiodic Modulatory character of energy-saving effect, environmental protection, degree of protection, luminous efficiency, light, the present invention has better performance characteristics than Traditional Man light source; Effectively improve marketable fish output and the quality of Atlantic salmon, increase economic efficiency, realize the object that volume increase reduces discharging with source.
