According to look the daily motion track following then be by on the mathematics to the predictor formula of track of sun, accurately calculate running track from sun theoretically, drive topworks by certain procedure and follow the tracks of the sun, shortcoming is the accuracy requirement height to system, cumulative errors is arranged, after often moving a period of time, just departed from position of sun gradually, so need the regular manual synchronizing of high-level professional and technical personnel.Compare with the tracking of photoelectricity enclosed, obtained wider application relatively.
Summary of the invention
The present invention be directed to the tracking of photoelectricity enclosed and be subjected to the big problem of weather effect, proposed a kind of solar tracking sensing device and method of work, can adapt to and neglect the fine cloudy weather of neglecting, under broken weather, also can follow the tracks of the sun all the time.

Embodiment
Sun-tracking sensor apparatus structure synoptic diagram as shown in Figure 1, device comprises first photoelectric sensor 1, second photoelectric sensor 2, sunshading board 3, solar energy tracking device base 4, helioplant 5, controller, helioplant 5 is a semisphere, slot type, flat, sunshading board 3 places on the solar energy tracking device base 4, first photoelectric sensor 1 and second photoelectric sensor 2 are close to sunshading board 3 both sides, solar energy tracking device base 4 is positioned at middle, helioplant 5 bottom, first photoelectric sensor 1 and second photoelectric sensor, 2 signals are sent into controller, and the controller output command drives helioplant 5 to topworks.
The principle of work and the course of work of following the tracks of the sun are as follows: under the first, the fine state, if the direct solar radiation that first photoelectric sensor 1 receives is big, the direct solar radiation that second photoelectric sensor 2 receives is little because second photoelectric sensor 2 is blocked by sunshading board 3, illustrate that then the sun is in first photoelectric sensor, 1 one sides, the sun is delivered to controller with this signal, controller sends instructions to topworks, helioplant 5 is rotated, till the direct solar radiation that first photoelectric sensor 1 and photoelectric sensor b receive equates to first photoelectric sensor, 1 one sides; Otherwise, if the direct solar radiation that first photoelectric sensor 1 receives is little, because second photoelectric sensor 2 is blocked by sunshading board 3, the direct solar radiation that second photoelectric sensor 2 receives is big, the sun then is described in second photoelectric sensor, 2 one sides, the sun is delivered to controller with this signal, and controller sends instructions to topworks, helioplant 5 is rotated, till the direct solar radiation that first photoelectric sensor 1 and second photoelectric sensor 2 receive equates to second photoelectric sensor, 2 one sides.So under the sunny weather, the present invention makes helioplant correct tracking position of sun always, as shown in Figure 2.
The second, weather is by clear to overcast, and then the beam radia that receives of first photoelectric sensor 1 and second photoelectric sensor 2 is all very little, utilizes setting value less than the sun, and controller quits work according to this signal.Out-of-work reason is: because beam radia is very little, value is little, whether follows the tracks of utilizations of not overslaugh sun scattered radiation energy, i.e. the utilization of scattered radiation need not to carry out solar tracking, and not following the tracks of to influence solar energy heating efficient.
Three, weather is by under the overcast to clear situation, if the direct solar radiation that first photoelectric sensor 1 receives is big, the direct solar radiation that second photoelectric sensor 2 receives is little, because second photoelectric sensor 2 is blocked by sunshading board 3, illustrate that then the sun is in first photoelectric sensor, 1 one sides, the sun is delivered to controller with this signal, controller sends instructions to topworks, helioplant 5 is rotated, till the direct solar radiation that first photoelectric sensor 1 and photoelectric sensor b receive equates to first photoelectric sensor, 1 one sides; Otherwise, if the direct solar radiation that first photoelectric sensor 1 receives is little, because second photoelectric sensor 2 is blocked by sunshading board 3, the direct solar radiation that second photoelectric sensor 2 receives is big, the sun then is described in second photoelectric sensor, 2 one sides, the sun is delivered to controller with this signal, and controller sends instructions to topworks, helioplant 5 is rotated, till the direct solar radiation that first photoelectric sensor 1 and second photoelectric sensor 2 receive equates to second photoelectric sensor, 2 one sides.So weather is by identical under the course of work after overcast to clear and the fine condition, the present invention can make helioplant under sunny or rain or shine indefinite situation, always can search out position of sun voluntarily.
The present invention can be applied to the solar tracking of slot type, dish formula concentrating collector, can both guarantee that under any weather condition the collecting efficiency of slot light collection heat collector is the highest.Also can be applied to the solar tracking of photovoltaic generating system, can both guarantee that under any weather condition the generating efficiency of photovoltaic generating system is the highest.
