Description

Solar tracking reflection cumulative tans by the sun experimental machine and employed sunlight tracing method
Technical field
The invention belongs to simulating natural environment accelerated material senile experiment control system technical field, be specifically related to the environmental aging of a kind of sun light tracking reinforcement nonmetallic materials and quicken to tan by the sun experimental machine and employed sunlight tracing method.
Technical background
Utilize the man-made derice that material for test is carried out the accelerated deterioration experiment, relevant report is all arranged both at home and abroad, but carry out often abroad, its principle all is to follow the tracks of sunshine, utilizing sunshine to carry out many times evenly assembles, the projection non-metal material surface, with the temperature humidity environment of setting, the simulating natural environment condition wears out and quickens this process.The overseas utilization sunshine is strengthened senile experiment to the field of nonmetallic materials and has also been formed standard, and the corresponding open-air report of strengthening senile experiment device and sunlight tracking system is also arranged simultaneously.But all there is certain defective in the external various open-air senile experiment device of strengthening.
The one, the external various open-air senile experiment device of strengthening does not have consideration protection problem to host computer system under the big dust storm condition in special areas such as desert, so these devices are restricted in uses of desert area.
The 2nd, the external various open-air experimental provision of strengthening is not seen relevant report to the protection of level crossing water smoke as yet, and these experimental provisions can be stained with water smoke inevitably, thereby can influence level crossing to sun reflection of light when simulation rain, mist condition on the catoptron.
The 3rd, domestic and international various sun light tracking modes adopt the light sensors intensity of illumination more, and with this as following the tracks of foundation, such as the radiometer that uses in meteorology detects, its one dimension track just adopts this mode.The patent No. is that electronic control part was just controlled the work of sunshine tracking device, reaches the purpose of automatic tracks sunlight after the Chinese patent of CN2040257 " full-automatic sunshine tracking device " by name had adopted the power and direction of photoreceptor sensing light.But owing to the influence of meteorologic phenomenas such as the influence of not considering other light sources and cloud layer, this tracking mode is subjected to external interference bigger in tracing process, can not realize the tracking to sunshine very accurately.
Summary of the invention
The objective of the invention is at having the deficiency that inside and outside device exists now, invent the environmental aging of a kind of sun light tracking reinforcement nonmetallic materials and quicken to tan by the sun experimental machine, main frame protective cover and level crossing water smoke protective device have been designed, has good preventive means, and the method that has adopted day point trajectory equation to be used to follow the tracks of daylight as the benchmark route, antijamming capability strengthens.
Ultimate principle of the present invention is: by day point trajectory equation tracking daylight, measure and the record intensity of illumination, measure test specimen and environment temperature simultaneously, and by cold wind unit adjusting test specimen oven temperature, degree, the misty rain of water spray/mist system simulation physical environment, the signal that the control system assembly receives each system carries out Long-distance Control, thereby the conditions such as solar irradiation in the simulating natural environment, rain, mist that reach are carried out the accelerated deterioration experiment to the nonmetallic materials test specimen.
Its technic relization scheme is as follows:
Solar tracking reflection cumulative of the present invention tans by the sun and includes frame, plane mirror, test specimen case, water supply unit, main control cabinet and computer control system on the experimental machine structure.Install in the frame Gear trainComputer control system includes the solar tracking control module, radiant quantity record measuring unit, temperature control unit, water spray/mist control module.The place that the present invention is different with existing apparatus is: computer control system also includes the protective cover control module, and the guard shield of setting up defences outside whole main frame is controlled its keying automatically by the protective cover control module; On plane mirror, be provided with bucker in addition, control its keying by the water spray control module.
It is to adopt a day point trajectory equation to be used to follow the tracks of daylight as the benchmark route that solar tracking reflection cumulative of the present invention tans by the sun the employed sunlight tracing method of experimental machine, it is specifically realized by the solar tracking control module in the computer control system, adds that by the mean value of proxima luce (prox. luc) equation of locus the influence at declination angle is as back one day day point initial track.Its control principle is: the angle that is provided day locus of points by the solar time clock, driving circuit sends signal, rotating drive sun reflection frame reaches given day point position, the day point tracker of reflection on the frame regularly provides day point tolerance orientation values and the given day locus of points comparison every day, if error greater than 5%, is revised a day point trajectory equation.
Therefore and both at home and abroad related invention is compared and be the invention has the advantages that:
The present invention is directed to the use of experimental machine, increased the main frame protective cover, be used under the excessive natural conditions of wind-force, preventing wind, husky destruction main frame in special areas such as deserts.
The present invention is provided with the level crossing bucker on level crossing, when system begins water spray when (mist), bucker is opened, and prevents that level crossing is infected with water smoke.
The present invention adopts day point trajectory equation as the sun light tracking foundation, just can get rid of the influence of these factors, exactly level crossing is aimed at the sun.On the error concealment mode, adopt day some parameter of collection at interval of fixing time to be used to adjust day mode of some track, with the interference of effective opposing environment.
