The principle of work of this tracking control system: the optical devices 32 on the said sunlight inductor 3 are sent to described controller 5 with the solar irradiation intensity data of collecting; When sunlight intensity reaches the threshold values of setting in the controller 5; Two groups of right-angle prisms 34 are differentiated solar azimuth; Controller 5 gets into light-operated tracing mode, and guiding deceleration topworks 4 follows the tracks of the sun; When optical devices 32 were sensed sunlight intensity and are lower than in the controller 5 threshold values of setting, controller 5 got into the time control tracing modes, according to sun travelling speed, and 4 operations of guiding deceleration topworks.
During use, see shown in Fig. 3-5, the prism angle A=arcsin (1/n) of right-angle prism 34 in the described sunlight inductor 3, wherein, n is the refractive index of prism, promptly A is the cirtical angle of total reflection of prism.The purpose of glass for infrared rays is to let the infrared light of the sun see through as far as possible, and the short wavelength light below the visible lights such as environment and cloud layer scattered light has just strengthened the ratio of direct sunlight so comparatively speaking as far as possible by the moon retaining.According to total reflection principle, when sunlight inductor 3 over against the solar time, about corresponding right-angle prism 34 simultaneously to direct light generation total reflection, at this moment, solar battery sheet 35 receives light identical, sends identical electric signal.And when the sun appears at the left side; The right-angle prism 34 suffered sunshines on the right arrive hypotenuse after reflecting, its incident angle is less than the cirtical angle of total reflection, and light has transmitted prism; And the right-angle prism 34 suffered sunshines on the left side are when refraction arrives hypotenuse; Incident angle is greater than the cirtical angle of total reflection, and light is through being totally reflected to solar battery sheet 35, and corresponding two battery sheets 35 produce the electric signal that differs greatly.In like manner, when the sun appears at the right, left side sunshine will be gone out from right-angle prism 34 transmissions, and the sunshine on the right will arrive the right solar battery sheet 35 down owing to the effect of right-angle prism 34, and at this moment, the right produces higher electric signal.
In this; When sunlight reached the threshold values of controller 5 settings, corresponding, one group of right-angle prism 34 just can clearly be distinguished sun on the left side or the right; And convert light signal to electric signal in high sensitivity; With the motion of control deceleration topworks 4, to reach the purpose of following the tracks of the sun, this becomes light-operated tracing mode.Because the cirtical angle of total reflection is a sudden change turning point, so can reach very high tracking accuracy.
In addition; The situation of various complicacies can appear in weather; The photodiode 36 of the utility model middle-jiao yang, function of the spleen and stomach optical inductor 3 can be judged sun light intensity; When sun light intensity reached controller 5 and sets threshold values, the signal controlling deceleration topworks 4 that controller 5 sends through right-angle prism 34 was to follow the tracks of the sun; When sun light intensity is set threshold values less than controller 5; Block etc. such as overcast and rainy or cloud layer; When the pickup electrode that right-angle prism 34 sends is weak; Single-chip microcomputer in the controller 5 moves the operation of formula with control deceleration topworks 4 according to the clock chip timing and the sun wherein, the simulation tracing sun, and this is called the time control tracing mode.When the sun one comes out, the utility model gets into light-operated tracing mode again.
No matter whether the sun occurs, and the photodiode 36 in the sunlight inductor 3 all can get into corresponding light-operated and time control tracing mode by guide controller 5, therefore can realize the round-the-clock high precision tracking sun.
Certainly; The above is merely the specific embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
