Including transparent upper cover 5 and base 6；Above-mentioned terrace with edge 1 is fixedly mounted in transparent watertight shell.Solar energy automatic tracking sensor is whole
Body can be fixed on solar panel by base.
Embodiment 2
A kind of solar energy automatic tracking sensor of the utility model embodiment offer, as shown in Figure 1, 2, including shell, rib
Platform the 1st, shadow shield the 4th, 4 silicon photocell sensors, circuit board, operational amplifier and Aviation Connector 7.
Above-mentioned shell includes transparent upper cover 5 and base 6, and transparent upper cover 5 uses PMMA material, and base 6 uses ABS material system
Making, transparent upper cover 5 and base 6 are fixed by fluid sealant and seal, it is achieved the purpose of water proof and dust proof and protection internal sensor.
As in figure 2 it is shown, the silicon photocell sensor on the side of two, left and right constitutes one group of photoelectric measurement list working simultaneously
Unit, the silicon photocell sensor on upper and lower two sides constitutes another and organizes the opto-measurement unit simultaneously working, wherein left and right two
One group of photoelectric sensor of side is used for detecting the incident angle of sun North and South direction light, one group of photoelectric sensor of upper and lower both sides
It is used for detecting the incident angle of sun east-west direction light.Each silicon photocell sensor above-mentioned is blocked plate 4 coverage extent phase
With the shape of shadow shield is preferably identical with bottom surface with the upper bottom surface of terrace with edge 1, it is also possible to different, such as upper bottom surface and bottom surface
For square, shadow shield 4 is circle, it is only necessary to ensure that shadow shield 4 is identical to the coverage extent of each silicon photocell sensor.For
Playing the occlusion effect of necessity, the area of shadow shield 4 needs area more than upper bottom surface, and less than the area of bottom surface, as
Really the area of shadow shield 4 is more than the area of bottom surface, may cause when sunlight is approximately perpendicular to upper bottom surface, and each silicon photocell passes
The photosurface of sensor is all blocked the shadow occlusion of plate 4, causes losing the judgement to solar angle degree.
Above-mentioned 4 silicon photocell sensors are connected with the input of operational amplifier, and operational amplifier is connected with circuit board,
The output of circuit board connects Aviation Connector 7, and Aviation Connector 7 is connected with peripheral control unit.Solar energy automatic tracking sensor is whole
Body can be fixed on solar panel by base, and wherein terrace with edge 1 bottom surface is parallel to solar panel.
Under illumination condition, the photosurface of 4 silicon photocell sensors of solar energy automatic tracking sensor is respectively facing
Four direction, therefore in the case that the non-perpendicular upper bottom surface of sunlight is incident, the angle of the incident each photosurface of sunlight is different, causes 4
The light quantity that individual silicon photocell sensor receives is different, and then the voltage of output is also different, the output electricity of silicon photocell sensor
Pressure exports after operational amplifier operation amplifier, is connected with peripheral control unit through Aviation Connector 7.Controller is to 4 silicon photoelectricity
The output voltage of pond sensor compares, and determines the silicon photocell sensor of output voltage maximum, i.e. this silicon photocell sensing
Device is maximum with the angle of sunlight, and controller sends control instruction makes solar energy tracking mechanism drive solar panel to maximum
The direction motion at corresponding silicon photocell sensor place.Through the continuous angle measuring tracking adjustment solar panel,
Finally with sunlight close to vertical, now the output voltage of 4 silicon photocell sensors is consistent.
The above-mentioned mode being respectively provided with light sensor in each side of terrace with edge ensure that the incident from different directions equal energy of sunlight
Being received by light sensor, measurement angular range is big.Each side of terrace with edge can take with the angle of bottom surface and be less than more than 0 °
90 °, preferably 10 °～80 °, the measurement angle of now above-mentioned solar energy automatic tracking sensor and certainty of measurement are all preferable,
The present embodiment is specially 60 °.
As it is shown on figure 3, when the non-perpendicular upper bottom surface of sunlight is incident, in figure the silicon photocell sensor on right side photosurface with
The angle of sunlight is more than the photosurface of the silicon photocell sensor in left side and the angle of sunlight, therefore right side silicon photocell sensor
Output voltage more than the output voltage of left side silicon photocell sensor；Simultaneously because shadow shield 4 block effect, the silicon on right side
The photosurface of photocell sensor is blocked by less, the photosurface of the silicon photocell sensor in left side blocked by more greatly (as
Shown in Fig. 3, the photosurface almost all of the silicon photocell sensor on the left of this is in the shade of shadow shield), increase further
The output voltage of right side silicon photocell sensor and the difference of the output voltage of left side silicon photocell sensor, even if sunlight is inclined
I.e. considerable influence is produced to the output voltage of silicon photocell sensor from vertical minute angle, therefore sunlight can be accurately positioned
And tracking.
As shown in Figure 4, when the vertical upper bottom surface of sunlight is incident, shadow shield 4 is to the photosurface of each silicon photocell sensor
Coverage extent is identical, owing to each side and the angle of bottom surface of terrace with edge 1 are all identical, and now each silicon photocell sensor photosensitive
Face and the angle of sunlight are also all identical, and therefore the output voltage of each silicon photocell sensor also should equal or approximately equal.When
Output voltage is equal or approximately equal, then it is assumed that sunlight vertical incidence solar panel.
In sum, solar energy automatic tracking sensor of the present utility model had both had the scope of the bigger angle measured
There is again higher measurement tracking accuracy, finally improve tracking accuracy.Have simple in construction, with low cost, precision is high, work simultaneously
Make stable advantage.
