Abstract
The utility model provides a sun orientation device comprising a normal polyhedron which is fixedly arranged in a space capable of receiving sunlight, wherein each face of the normal polyhedron is at least paved with a sunlight sensing element; and all the faces are commonly provided with P sunlight sensing elements; and P is more than or equal to 3. The sun orientation device disclosed by the utility model utilizes solar cell sheets paved on the normal polyhedron to sense a variation tendency of sunlight intensity, so that the direction of the sun is determined. Compared with the prior art, the sun orientation device has the advantages of full field and no need of movement adjustment, and can utilize a weakening direction of the sunlight intensity to judge the direction of the sun and the like. Furthermore, the sun orientation device can judge the east direction according to the variation of the sunlight intensity in different time periods. Moreover, the orientation can be realized by more accurately utilizing a light intensity difference, but not utilizing the quantitative light intensity (the same powder) and a vector direction; and 360-degree full-field orientation is provided under the precondition of not changing the position and the direction of the device.
Description
Technical field
The utility model belongs to the helioplant technical field, particularly relates to a kind of sun-orientation device.
Background technology
Sun power is as the green energy resource of the most direct environmental protection, playing crucial effects aspect modern society's energy structure changing, and at present mostly the application of sunshine is the power source of energy as modern mechanical; But using seldom such as other sides such as utilizing sun power location, navigation.And a precondition being arranged above-mentioned when using aspect these, that is exactly at first must carry out accurate orientation to the sun.
Adopt sun sensor at the device that is used for sun-orientation such as the devices such as satellite as space equipment at present more, they all are to adopt CMOS or APS as active photo-sensitive cell, all need light to introduce, the visual field restriction is arranged, all adopt electric rotation shaft adjust reciever to, and the device that is used for sun-orientation now nearly all is earlier to sun-orientation, adjusting miscellaneous equipment or device again makes it align the sun, that is to say that existing these sun-orientation devices all are the service of the tracking sun, and can't utilize the direction that weakens of sun light intensity to judge solar direction.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of reasonable in design, simple, and full visual field need not the sun-orientation device that moves and adjust.
In order to achieve the above object, the sun-orientation device that the utility model provides comprises a regular polygon that is fixedly installed in the space that can receive sunshine, at least be equipped with a sunshine primary element on each face of regular polygon, P sunshine primary element is set on all faces altogether, and P 〉=3.
Described sunshine primary element is solar battery sheet.
Described sunshine primary element links to each other with measurement mechanism.
Described sun-orientation device also comprises a bearing that plays fixation that is connected the regular polygon lower end.
The sun-orientation device that the utility model provides is to utilize the solar battery sheet of laying on the regular polygon to experience the variation tendency of sun light intensity, comes to determine solar direction thus.Than prior art, have full visual field, an adjustment of need not moving, can utilize the direction that weakens of sun light intensity to judge advantages such as solar direction.In addition, it can also judge east according to different time sun intensity variations.In addition, it is directed that this device can utilize light intensity difference rather than quantitative light intensity (same power) and direction vector more accurately, and can the position of modifier not and towards prerequisite under the full visual field orientations of 360 degree are provided.
Description of drawings
The sun-orientation apparatus structure synoptic diagram that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the sun-orientation device that the utility model provides is elaborated.
As shown in Figure 1, the sun-orientation device that the utility model provides comprises a regular polygon 1 that is fixedly installed in the space that can receive sunshine, at least be equipped with a sunshine primary element 2 on each face of regular polygon 1, P sunshine primary element 2 is set on all faces altogether, and P 〉=3.
Described sunshine primary element 2 is solar battery sheet.
Described sunshine primary element 2 links to each other with measurement mechanism.
Described sun-orientation device also comprises a bearing 3 that plays fixation that is connected the regular polygon lower end.
Be that regular dodecahedron is that example is described below the sun-orientation device principle of work that the utility model provides with regular polygon 1 now:
As shown in Figure 1, the regular polygon 1 in the sun-orientation device that present embodiment provides is regular dodecahedron, is arranged on the bearing 3, P solar battery sheet is housed altogether as sunshine primary element 2 on all faces, and the normal vector of P solar battery sheet is:
The form that the normal vector on each plane is put by regular polygon 1 determined, i=3 wherein, and 4 ..., P.
At first utilize the measurement mechanism measurement that links to each other with solar battery sheet and note the sunshine total intensity value of experiencing on each solar battery sheet, calculate the sunlight intensity value J that unit area is experienced on each solar battery sheet according to above-mentioned sunshine total intensity value then
i, i=1 wherein ..., P.
Utilize the sunlight intensity value J of the above-mentioned unit area that calculates
iDetermine at least S unit and experience the solar battery sheet of sun light intensity maximum, wherein 1≤S≤P calculates then
With
As solar direction; Utilize the sunlight intensity value J of the above-mentioned unit area that calculates
i, adopt statistical method can obtain equal strength band on this regular polygon 1, just can determine the direction of the sun by analyzing strength-enhanced direction on these intensity bands:
Further utilize
With
Calculate the source side of correction to vector
Be fixed solar direction.
Since utilize solar direction that this sun-orientation device makes for follow-up, utilize the sun to locate and navigation Service; it is not pure sun steady arm; therefore although the utility model claims restriction of enclosing is the sun-orientation device; but the those skilled in the art should be understood that; in the spirit and scope that do not break away from the whole claims of the utility model; the various variations of on any form and the details the utility model being made are protection domain of the present utility model.
