Further, the plane of the light source 300 that is set on lower wall 120 and setting light-transmitting plate 200 can be separated by least one away from From ds.Also that is, the plane on the surface substantially perpendicular to setting light-transmitting plate 200, light source 300 can preferably be separated by an at least distance ds.In particular, the plane on the surface substantially perpendicular to setting light-transmitting plate 200, at least one of the light-emitting surface 310 of light source 300 An at least distance ds can be separated by with the plane on the surface of setting light-transmitting plate 200 by dividing.This distance ds can further cooperate light-transmitting plate 200 Opening area, light source 300 the factors such as light source dispersion angle be adjusted cooperation, to promote the accuracy and/or spirit of measurement Sensitivity.Similarly, the plane of the first optical sensor 400 and setting light-transmitting plate 200 that are set on lower wall 120 can be separated by least One distance d1.Also that is, the plane on the surface substantially perpendicular to setting light-transmitting plate 200, the first optical sensor 400 can preferably be separated by An at least distance d1.In particular, the plane on the surface substantially perpendicular to setting light-transmitting plate 200, the light of the first optical sensor 400 At least part of receiving plane 410 and the plane on the surface of setting light-transmitting plate 200 can be separated by an at least distance d1.This distance d1 can Further adjustment, can receive with not covering penetrating from light-transmitting plate 200 or specular scattering light and close enough light-transmitting plate 200 To penetrating from light-transmitting plate 200 or specular scattering light.Whereby, the light that light source 300 is issued can be incident on light-transmitting plate 200, And institute's specular scattering or the light penetrated can be incident to the first optical sensor 400 from light-transmitting plate 200.

Here, light source 300 can be the directing light source with direction light-transmitting plate 200 as shown in Figures 1 and 2 or can be The ball-type light source or other suitable light sources to shine towards wide direction.In addition, light source 300 can be various types of light sources, such as It can be fluorescent lamp, light emitting diode (LED), laser or other suitable types.Correspondingly, the first optical sensor 400 can be The optical sensor of any size (also that is, intensity) that can receive and measure the light that above-mentioned specific light source 300 is issued.

An embodiment according to the present invention, in one sensing light 510 of the transmitting of light source 300, the first optical sensor 400 be can receive And it measures sensing light 510 and is incident upon the sensing scattering light 560 that the light-transmitting plate 200 is scattered, and the dust in environment space 1000 1050 dust fall amount or the dust fall amount of the dust 1050 ' in an object 15 being set in environment space 1000 and the sensing The size of scattering light 560 is positively correlated.

From the above, dust investigating 10 is described in detail hereinafter with reference to Fig. 3 A and Fig. 3 B and scatters light by sensing The method of 560 measurements and assessment dust fall degree.

Referring to Fig. 3 A, when the dust 1050 in environment space 1000 is not yet fallen on light-transmitting plate 200, dust investigating 10 light source 300 towards the sensing light 510 that light-transmitting plate 200 is emitted can significantly penetrate light-transmitting plate 200 and with emergent light 530 Form be directly emitted or scatter in environment space 1000.At this moment, only a small number of or even without sensing light 510 via saturating Tabula rasa 200 scatters and is incident to the first optical sensor 400 to sense the form of scattering light 560.Therefore, when dust fall amount is lower or When about zero, the first optical sensor 400 can receive and measure sensing scattering light 560 intensity it is smaller or be approximately close to zero.

Under opposite, referring to Fig. 3 B, when the dust 1050 in environment space 1000 falls within light-transmitting plate 200 and it is piled up in light transmission When on plate 200, the light source 300 of dust investigating 10 can be because of the powder accumulated towards the sensing light 510 that light-transmitting plate 200 is emitted Dirt 1050 and reduce and penetrate the intensity of the emergent light 530 being emitted in environment space 1000, and will increase sensing light 510 by saturating The dust 1050 accumulated on tabula rasa 200 stops and what is scattered senses the intensity for scattering light 560.At this moment, increase the sensing of intensity Scattering light 560 can be incident to the first optical sensor 400.Therefore, when having certain dust fall amount on light-transmitting plate 200, the first light is passed Sensor 400 can receive and measure the intensity increase of sensing scattering light 560, and the quantity for the dust 1050 accumulated or degree and sense The size for surveying scattering light 560 is positively correlated.In other words, the degree of sedimentating dust 1050 is higher, the size of sensing scattering light 560 (that is, intensity) will be higher.

Hold it is above-mentioned, can sensing scattering light 560 measured by the first optical sensor 400 by dust investigating 10 it is big The small accumulation degree to estimate the dust 1050 on the light-transmitting plate 200 for being stacked over dust investigating 10.Whereby, it please also refer to Fig. 1 can be corresponded to and be estimated the dust fall situation of the dust 1050 ' on the special object 15 in environment space 1000 and (such as fall Dust quantity or dust fall accumulate degree), or the dust fall for estimating the dust 1050 in this environment space 1000 is corresponded to according to the time cycle Situation (such as dust fall amount or dust fall frequency or dust fall opportunity).

The spectral region of an embodiment according to the present invention, the sensing light 510 that light source 300 is issued can be according to environment space Depending on the type of dust 1050 in 1000.For example, the particle of spectral wavelength and dust based on sensing light 510 is big It is small, it might have sensing light 510 and be directed through dust 1050 and be not easy to be scattered.Therefore, in order to promote measurement accuracy and/ Or sensitivity, the spectral region of sensing light 510 can be determined according to the type of the dust 1050 in environment space 1000, so that sense Survey light 510 can be predetermined the dust 1050 to be measured and be scattered.For example, Source of Dust may be, for example, greasy dirt, sea salt, Volcanic ash, black sand, flour, wood dust, soil etc., and an embodiment according to the present invention can according in environment space 1000 most Big Source of Dust, most possible Source of Dust are expected the type of detecting Source of Dust to determine or adjust the sensing light to be used 510 spectral region, and then improve the accuracy and/or sensitivity of measurement dust fall degree.

According to a preferred embodiment of the present invention, if light source 300 is light emitting diode, sensing that light source 300 is issued The spectral region of light 510 for example can be between about 300nm between about 1100nm.When the spectral region for the light that light source 300 is issued When falling within this range, many commercially available photoelectricity measurement instruments can be used as the first optical sensor 400.In addition, if required measurement dust fall degree Object 15 when being solar panel, to also correspond to solar panel mainly available for spectral region of this sensing light 510 Solar energy spectral region.For example, the size of sensing scattering light 560, which can more relevantly reflect, may reduce the sun The dust fall degree of the dust 1050 and 1050 ' of the generated output of energy solar panel.Also that is, can more relevantly reflect that those can be hindered The dust of the solar panel mainly particular size or type of available light (substantially ultraviolet light near infrared light) incidence 1050 and 1050 ' dust fall degree.Opposite, those do not easily cause the scattering of sensing light 510 can for the dust of sensing scattering light 560 Can reception sun light efficiency for solar panel and generating efficiency do not have too big influence.However, above-mentioned spectral region It is merely illustrative, and the invention is not limited thereto.

Then, the dust investigating of each alternate embodiment according to the present invention will be illustrated referring to Fig. 4 A to Fig. 4 D.Its In, and it may omit referring to figs. 1 to the same or similar details of Fig. 3 B or simply just illustrate, and will mainly illustrate it herein The difference different from dust investigating 10 shown in Fig. 1 to Fig. 3 B.

Hereinafter, Fig. 5 and Fig. 6 will be referred to further to illustrate dust investigating according to another embodiment of the present invention And its actuation of corresponding check and evaluation dust fall degree.

An embodiment according to the present invention can further be arranged one second optical sensor 600 and set with the first optical sensor 400 It is placed in not existing together in enclosed space 25, to measure the size for the sensing light being directly emitted from light source 300.For example, the second light passes Sensor 600 can be set on the first wall body in those wall bodies 110 to 160 with light-transmitting plate 200, and first optical sensor 400 It may be disposed in those wall bodies 110 to 160 on the second wall body for being different from the first wall body with light source 300.For example, referring to figure 5, it is similar to Fig. 1 and embodiment shown in Fig. 2, dust investigating 20 may include light source 300 and the setting of the first optical sensor 400 In on lower wall 120, and it can further include the second optical sensor 600 and be set on wall body 110.

It holds, light source 300 and the first optical sensor 400 can be respectively relative to light-transmitting plate 200 and be set to both sides, and the second light Sensor 600 can be set to different location with the first optical sensor 400, so that being emitted and scattering from light transmission from light source 300 The sensing scattering light 560 of plate 200 can be incident to the first optical sensor 400 without being incident to the second optical sensor 600.Citing and Speech, the second optical sensor 600 can be for example comprising matrix 620 and an at least light receiving surface 610, and light receiving surface 610 is towards light Source 300 and not towards light-transmitting plate 200.Also that is, referring to Fig. 6, the second optical sensor 600 is located at the sensing light 510 ' of light source 300 On possible path, but not position sensing on the possible path for scattering light 560 in light source 300.It configures according to this, the second optical sensor 600, which can receive the sensing light 510 ' that light source 300 directly emits, senses light 510 ' to measure, but not receives sensing and dissipate Penetrate light 560.

In addition, according to a preferred embodiment of the present invention, be not easy to accurately measure the size of sensing light 510 ' by Possibility incident light in the be incident to enclosed space 25 of light-transmitting plate 200 is influenced, and the second optical sensor 600 may be disposed at one Position, and (for example, Fig. 5 and Fig. 6 is to put down where upper wall body 110 when the position is projected in plane set by light-transmitting plate 200 Face) an at least distance d2 can be separated by with light-transmitting plate 200.In particular, the light receiving surface 610 of the second optical sensor 600 is projected in An at least distance d2 can be separated by when in plane set by tabula rasa 200 with light-transmitting plate 200.Also that is, the second optical sensor 600 is (special It is not light receiving surface 610) in 200 place plane of light-transmitting plate or in the upright projection range and light transmission of 200 place plane of light-transmitting plate Plate 200 can not be overlapped, so that being difficult to be incident to the second optical sensor 600 through the light of the scattering of light-transmitting plate 200 or incidence.Therefore, The size for the sensing light 510 ' for being received and being measured by the second optical sensor 600 will be more accurate.

In order to be emitted sensing light 510 and 510 ' simultaneously to light-transmitting plate 200 and the second optical sensor 600, according to the present invention one A little embodiments, light source 300 can be preferably a ball-type light source, and have the light-emitting surface 310 of curved surface or ball-type.It holds, the first light passes Sensor 400 can have an at least light receiving surface 410 to receive the sensing scattering light 560 scattered indirectly, and the second optical sensor 600 can With an at least light receiving surface 610 towards and in face of light-emitting surface 310 to receive and measure the sensing light 510 ' being directly emitted.Separately Outside, in the case where light source 300 is ball-type light source, as shown in figure 5, receiving the sensing being directly emitted to reduce by the first optical sensor 400 Light 510, the first optical sensor 400 can preferably be located on same wall body with light source 300, and in order to reduce the sense for receiving and scattering indirectly Scattering light 560 is surveyed, the second optical sensor 600 can be located on same wall body with light-transmitting plate 200.Therefore, the first optical sensor 400 with Second optical sensor 600 can be located separately on different wall bodies.However, above are only example, and the invention is not limited thereto.

It holds, referring to Fig. 6, when the one sensing light 510 of the transmitting of light source 300 of the dust investigating 20 configured as shown in Figure 5 When, which can be similar to described above be incident to light-transmitting plate 200 and scatter through light-transmitting plate 200, the sensing then reflected Scattering light 560 can be incident in the first optical sensor 400 and be received and measure.Meanwhile by same light source 300 towards different directions institute The sensing light 510 ' of transmitting can also be directly transmitted to the second optical sensor 600, and received and surveyed by the second optical sensor 600 Amount.Here, emitted by sensing light 510 and sensing light 510 ' by same light source 300, it is substantially visually same to sense light 510 and sensing light 510 ' be same emergent light, with being proportional between the emergent light of same intensity or its intensity or in just The emergent light of relationship.

According to some embodiments of the present invention, regulation light source 300 can be come by the second optical sensor 600 of above-mentioned configuration It is influenced brought by the luminous variation of body.For example, if light source 300 is unstable when shining and therefore intensity is fluctuated, or When person is light source 300 due to the factors such as decaying or deteriorating and luminous intensity is caused to reduce, it can be surveyed by the second optical sensor 600 The size of the sensing light 510 ' of amount scatters the dust fall degree that light 560 is estimated based on sensing to calibrate.Also that is, environment space 1000 In dust fall situation or the dust fall situation on the object in the environment space 1000 can be considered opposite with sensing scattering light 560 It is positively correlated in the ratio of sensing light 510 '.

Hereinafter, it will show that other include each alternate embodiment of the dust investigating of the second optical sensor 600.

Referring to Fig. 7 A, an alternate embodiment according to the present invention, dust investigating 20-1 and above-mentioned dust investigating 20 difference is that the second optical sensor 600 can be located in Different Plane with light-transmitting plate 200.Specifically, although the second light passes Sensor 600 can be equally set on upper wall body 110 with light-transmitting plate 200, but the second optical sensor 600 can be hung on hang On upper wall body 110, so that the light receiving surface 610 of the second optical sensor 600 is closer to light source 300.Therefore, it can more directly measure The intensity for the sensing light 510 ' that light source 300 is emitted, and reduce the deviation that may cause in transmittance process of sensing light 510 ' or Decaying.Under this arrangement, it is put down as where the second optical sensor 600 and light source 300 in the upper wall body 110 of setting light-transmitting plate 200 The upright projection range in face and the opposite both sides for being not located at light-transmitting plate 200, therefore light is scattered by the sensing that light-transmitting plate 200 is scattered 560 can't be incident to the second optical sensor 600.
