Background technology
Because the irradiating angle of the sun changes, utilize at present in the method for solar electrical energy generation, in order to improve generating efficiency, reception sunlight as much as possible in limited area, all relate to sunshine tracking problem, how to allow sunshine incident direction parallel with receiver normal direction.Current sunshine tracking scheme is mainly that track of sun calculates, photoelectric sensor is followed the tracks of and current detecting is followed the tracks of, and wherein photoelectric tracking mainly contains shadow method and electric signal analytical comparison.Existing photoelectric sensing scheme generally needs multiple sensors, precision is poor, acquisition range is narrow, not strong to environmental suitability, generally need independent linear optics sensing element that intensity of illumination is gathered and just can be determined whether as the cloudy day, so not only improve energy consumption, also made cost increase.
Summary of the invention
Exist defect to the present invention proposes a kind of sunlight tracing scheme based on diffuse scattering in order to solve above-mentioned photoelectric sensing scheme, it can gather direct sunlight and scattered light (surround lighting) simultaneously, and only use single linear sensing element, cost is low, precision is high, energy consumption low to good environmental adaptability, can realize continuous location.
Technical scheme of the present invention is: a kind of diffuse scattering sunlight tracing sensor, comprise lighting cylinder, light absorbent, diffuse scattering layer, reflection horizon, photoelectric sensor and substrate, lighting cylinder is arranged on substrate, diffuse scattering layer is positioned at lighting cylinder inside surface medium position, lighting cylinder inwall more than diffuse scattering layer scribbles light absorbent, and on diffuse scattering layer, have a center light hole, photoelectric sensor is positioned at the below of center light hole, and be arranged on substrate, the lighting cylinder inwall below diffuse scattering layer scribbles reflection horizon.
As preferably, described diffuse scattering sunlight tracing sensor, is characterized in that lighting cylinder inside surface is cylindrical shape.
As preferably, described diffuse scattering sunlight tracing sensor, is characterized in that center light hole axis and the dead in line of lighting cylinder inside surface.
As preferably, described diffuse scattering sunlight tracing sensor, is characterized in that the surface that diffuse scattering layer contacts with light absorbent is plane, and has center light hole in this lip-deep geometric center position.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is made a detailed explanation.
Diffuse scattering sunlight tracing sensor as shown in Figure 1, comprises lighting cylinder (1), light absorbent (2), diffuse scattering layer (3), center light hole (3-1), reflection horizon (4), photoelectric sensor (5) and substrate (6).Lighting cylinder (1) is arranged on substrate (6), diffuse scattering layer (3) is positioned at lighting cylinder (1) inside surface medium position, lighting cylinder (1) inwall more than diffuse scattering layer (3) scribbles light absorbent (2), and on diffuse scattering layer (3), have a center light hole (3-1), photoelectric sensor (5) is positioned at the below of center light hole (3-1), and it is upper to be arranged on substrate (6), lighting cylinder (1) inwall below diffuse scattering layer (3) scribbles reflection horizon (4).
Sunlight is irradiated on lighting cylinder (1) at a certain angle, a part is sponged by light absorbent (2), another part is irradiated on photoelectric sensor (5) after by diffuse scattering layer (3), along with the difference of sunlight angle, intensity of illumination in diffuse-reflective cavity and the angle of incidence of sunlight degree relation that is inversely proportional to, realize direct sunlight and environment scattered light gathers simultaneously, and because sunlight is just irradiated on photoelectric sensor (5) through diffuse scattering layer (3), reduce intensity of illumination, solve ordinary optical sensor and in the time that solar radiation is sufficient, exceeded range phenomenon.Incide the reflection through reflection horizon (4) of light in diffuse-reflective cavity, can in diffuse-reflective cavity, carry out interreflection, thereby improve brightness in diffuse-reflective cavity.When the axis of lighting cylinder (1) is in the time that sunlight incident direction is parallel, sunlight is directly injected by center light hole (3-1), the intensity of illumination that photoelectric sensor (5) is subject to has a very large variation, thereby can realize in some cases quick and precisely location.System is only used a linear optics sensor, has reduced energy consumption and cost.What device had well solved that traditional photoelectric sensing scheme exists can not continuous acquisition, precision is low, cost is high, energy consumption is large, can not adapt to the problems such as multiple weather condition, is particularly suitable for being used in conjunction with track of sun calculating tracing.
The above embodiments are only a kind of concrete design, and the utility model should be not limited to the limitation of above-described embodiment, and all designs that meets the utility model spirit all should be included in protection domain of the present utility model.
