Description

The present invention relates to a sun ray information providing system and a sun ray information providing program.

Recently, the influence of sunlight (for example, ultraviolet rays, visible rays and infrared rays) on the human body and living environment is known, and the amount of sunlight irradiation (for example, ultraviolet irradiation amount and solar radiation amount) has begun to attract attention.

For example, in the real world, the parts and places where you want to know the energy intensity such as the amount of ultraviolet irradiation and the amount of solar radiation are not necessarily the horizontal plane and the plane perpendicular to the sun's rays. In order to know the energy intensity of such various parts and places, it is conceivable to calculate the energy intensity on the actual irradiation surface from the energy intensity perpendicular to the horizontal plane and sunlight by using trigonometric functions.

The direction-specific sunlight intensity information includes the location information and the direction information indicating the direction in which the irradiation surface to be irradiated by the sunlight is directed, and the direction-specific sunlight intensity information is the date and time indicated by the date and time information and the location indicated by the location information. Information including the intensity of the sun's rays received by the irradiation surface indicated by the direction information, and the communication unit refers to the source of the sun's ray inquiry information with respect to the direction-specific sun's rays calculated by the second calculation unit. It is characterized by transmitting intensity information.

In this case, the client machine and the server machine may be the same device, or the client machine and the server machine may be connected by a bus, for example. When the client machine and the server machine are the same device, connecting the client machine and the server machine means that the program that realizes the function as the client machine and the program that realizes the function as the server machine are data via memory or the like.

The storage unit 13 has date and time information 14 which is information about the date and time, place information 15 which is information about the place, and sun rays which are information about the intensity of the sun rays at the place indicated by the date and time information 14 and the place information 15. The strength information 16 is stored in association with each other.

The communication unit 17 of the solar ray information providing system 10 is connected to a network 4 such as the Internet. Client machines 2 and 3 used by the user are connected to the network 4, and the client machines 2 and 3 communicate with the solar ray information providing system 10 via the network 4.

The sun ray inquiry information is transmitted from the client machine 2 or the client machine 3 to the sun ray information providing system 10 via the network 4. The sun ray inquiry information includes date and time information 14, location information 15, and direction information 16a indicating the direction in which the irradiation surface to be irradiated by the sun rays faces. The direction indicated by the direction information 16a is a direction orthogonal to the surface on which the irradiation surface to be irradiated by the sun's rays spreads. The direction information 16a will be described later with reference to FIGS. 2 to 5. The calculation result by the calculation unit 11 is transmitted from the solar ray information providing system 10 to the client machine 2 or the client machine 3 which is the transmission source of the solar ray inquiry information via the network 4.

Send to.

The direction information 16a will be described below. FIG. 2 is a diagram for explaining the irradiation direction of the sun's rays. FIG. 3 is a diagram for explaining the sun rays radiated to the irradiation surface A, which is a surface parallel to the ground. FIG. 4 is a diagram for explaining the sun rays radiated to the irradiation surface B, which is a surface forming an angle of 30 ° with the ground. FIG. 5 is a diagram for explaining the sun rays radiated to the irradiation surface C, which is a surface forming an angle of 90 ° with the ground. In FIGS. 3, 4 and 5, the direction in which the irradiation surface to be irradiated by the sun's rays faces, that is, the direction indicated by the direction information 16a is described as the “direction of the irradiation surface”.

As shown in FIG. 2, the sun rays radiated on the earth include direct solar radiation emitted from the direction of the sun and scattered solar radiation emitted from a direction other than the direction of the sun. Scattered solar radiation is emitted from the entire sky onto the irradiated surface. As shown in FIG. 3, the irradiation surface A, which is a surface parallel to the ground, is irradiated with scattered solar radiation and direct solar radiation from the entire sky.

Further, as shown in FIG. 4, the irradiation surface B forming an angle of 30 ° with the ground is irradiated with scattered solar radiation and direct solar radiation from the direction in which the irradiation surface B faces in the entire sky. Further, as shown in FIG. 5, the irradiation surface C forming an angle of 90 ° with the ground is not irradiated with direct solar radiation because the direction of the sun is the back side of the irradiation surface C, and the irradiation surface in the entire sky. Scattered solar radiation is emitted from the direction in which C faces. In addition to scattered sunlight and direct sunlight that are directly irradiated on the irradiated surface, there are also sunlight that is reflected on the ground and irradiated on the irradiated surface.

As can be seen with reference to FIGS. 3, 4 and 5, the intensity of the irradiated sun rays varies greatly depending on the direction in which the irradiation surface faces. Therefore, in this embodiment, different direction-specific solar ray intensity information is calculated for each direction in which the irradiation surface faces, and this is provided to the client machine 2 or the client machine 3 which is the transmission source of the solar ray inquiry information.

In this embodiment, in addition to scattered solar radiation and direct solar radiation, sunlight rays that are reflected by other irradiation surfaces such as the ground and wall surface and are applied to the irradiation surface can also be considered. This point will be described with reference to FIG. FIG. 6 is a diagram illustrating a sun ray that is reflected by the irradiation surface E and is applied to the irradiation surface D.

In an actual environment, the amount of solar radiation received by the irradiation surface D is not limited to the sunlight (direct solar radiation and scattered solar radiation) directly received by the irradiation surface D, but also the sunlight (direct solar radiation and scattered solar radiation) on the ground and wall surface. In addition, the sun rays (reflected light) reflected by the irradiation surface (irradiation surface E) are also included. In this embodiment, by including the intensity of the reflected light reflected by the irradiation surface in addition to the intensity of the sunlight rays received by the irradiation surface, the accuracy of obtaining the intensity of the sunlight rays received by the irradiation surface can be further improved.

Usually, the reflectance of the other irradiation surface is used for the calculation of the reflected light by the other irradiation surface. The reflectance of the surface of a substance is generally the reflectance of a typical specific wavelength, but it is desirable to calculate the reflectance using the spectral reflectance in order to calculate the energy intensity accurately. Here, how to obtain the spectral reflectance of the other irradiation surface will be described with reference to FIG. 7.

FIG. 7 is a diagram for explaining an example of how to obtain the spectral reflectance of the other irradiation surface, and FIG. 7A is a diagram showing a state of measuring the sunlight rays directly received by the irradiation surface E, and FIG. (B) is a figure which shows the state of measuring the reflected light by the irradiation surface E. As shown in FIGS. 7 (a) and 7 (b), the measuring instrument 50 is used here. The measuring device 50 is a measuring device that functions as a spectrophotometer. First, as shown in FIG. 7A, the spectral illuminance from above the irradiation surface E, which is another irradiation surface, (the spectral illuminance of the sun's rays irradiating the irradiation surface E) is measured using the measuring device 50. Further, the measuring instrument 50 is used to measure the spectral illuminance reflected on the irradiation surface E (the spectral illuminance of the reflected light reflected by the sunlight rays on the irradiation surface E). The spectral reflectance of the irradiation surface E is obtained by Equation 1 using the obtained spectral illuminance from above the irradiation surface E and the spectral illuminance reflected by the irradiation surface E.

Next, the calculation of the irradiation energy received by the irradiation surface using the spectral reflectance obtained in Equation 1 will be described. FIG. 8 is a diagram for explaining the light that enters the irradiated surface among the reflected light from the other irradiated surface. FIG. 8 shows a case where the irradiation surface G, which is another irradiation surface, is the ground, and the ratio of the reflected light from the irradiation surface G to the irradiation surface F is taken into consideration. The energy of light entering the irradiation surface F from the irradiation surface G (ground) can be calculated by Equation 2.

The irradiation energy received by the irradiation surface G in Equation 2 can be obtained, for example, by the method shown in FIG. 7A. As the reflectance in Equation 2, for example, the spectral reflectance obtained in Equation 1 can be used. The area ratio H in Equation 2 can be obtained as described below with reference to FIG. In FIG. 8, the visual field area of the ground (irradiation surface G) on the irradiation surface F is determined by the angle θ according to the direction of the irradiation surface F. If the irradiation surface G is the ideal ground (horizontal), the angle θ that determines the visual field area of the irradiation surface G, which is the ground, is geometrically an angle formed by the irradiation surface F and the horizontal direction. However, in reality, it is necessary to consider the change in topography, or to consider that the farther the irradiation surface G is from the irradiation surface F, the less reflected light is incident on the irradiation surface F, and the contribution is attenuated. Often, the angle θ should be determined according to the required accuracy.

The ratio of the visual field area of the ground on the irradiation surface F to the hemispherical area of the irradiation surface F is the area ratio H. In this embodiment, when the irradiation energy received by the irradiation surface F is obtained, the energy entering the irradiation surface F obtained in Equation 2 is added to the irradiation energy due to the scattered solar radiation and the direct solar radiation directly applied to the irradiation surface F. By adding it, it can be obtained with higher accuracy. Further, in Equation 2, the ground is considered as the other irradiation surface, but by considering not only the reflected light by the ground but also all other irradiation surfaces on which the reflected light can be incident on the irradiation surface F, the irradiation surface F can be changed. The irradiation energy to be received can be obtained with higher accuracy.

FIG. 9 is a diagram showing an example of information stored in the storage unit 13 shown in FIG. The storage unit 13 stores the information shown in FIG. 9, for example, in a database format. The storage unit 13 stores the date and time information 14 as the first primary key. The date and time information 14 may include a year, a month, a day, and an hour. The storage unit 13 stores the location information 15 as the second primary key. The location information 15 is information for identifying a position on the earth by using, for example, east longitude and north latitude.

The storage unit 13 stores the sun solid angle of the first primary key and the second primary key as the stored value of the sun ray intensity information 16. The storage unit 13 stores the direct solar radiation intensity of the first primary key and the second primary key as the stored value of the sunlight intensity information 16. The storage unit 13 stores the scattered solar radiation intensity of the first primary key and the second primary key as the stored value of the sunlight intensity information 16. The storage unit 13 stores the albedo values of the first primary key and the second primary key as the stored value of the sunlight intensity information 16. The albedo value is the ratio of the reflected sunlight intensity to the irradiated sunlight intensity. For example, in a certain area where the location information 15 is present, the ground is soil and the albedo value is low when the date and time information 14 is summer, and the ground is snow when the date and time information 14 is winter. The albedo value is high. For each value shown in FIG. 9, for example, actually measured values are collected and stored in the storage unit 13. The direction information 16a included in the sun ray intensity information 16 is included in the stored value shown in FIG. The information included in the sunlight intensity information 16 includes, for example, a value calculated by solving the radiation transmission equation and a value calculated in the process of solving the radiation transmission equation.

FIG. 10 is a flowchart showing the operation of the sun ray information providing system 10 shown in FIG. In step S71, it is determined whether or not the sunlight inquiry information from the client machine 2 or the client machine 3 has been received via the network 4. If the sun ray inquiry information is received (step S71: Yes), the process proceeds to step S72, and if the sun ray inquiry information is not received (step S71: No), the process returns to step S71.

Sunlight intensity information 16 which is information including the intensity of light rays is calculated and stored in the storage unit 13. The sunlight intensity information 16 is calculated using, for example, a radiation transfer equation.

In step S73, the solar ray intensity information 16 calculated in step S72 is mathematically calculated using the direction information 16 as an input value, so that the date and time indicated by the date and time information 14 is included in the sunlight inquiry information. At the place indicated by the information 15, the direction-specific solar ray intensity information, which is the sunlight ray intensity information received by the irradiation surface indicated by the direction information 16a, is calculated.

In step S74, the direction-specific sunlight intensity information indicating the direction-specific sunlight intensity calculated in step S73 is transmitted to the client machine 2 or the client machine 3 which is the source of the current sunlight inquiry information via the network 4. To do. The client machine 2 or the client machine 3 can obtain the direction-specific sunlight intensity information only by transmitting the sunlight inquiry information including the date / time information 14, the location information 15 and the direction information 16a to the sunlight information providing system 10. , More detailed sun ray information can be easily obtained. The client machine 2 or the client machine 3 can provide various applications to the end user by using the direction-specific sun ray intensity information obtained from the sun ray information providing system 10.

In this embodiment, in the configuration shown in FIG. 1, the solar ray information providing system 10 can calculate the irradiation heat amount. FIG. 13 is a graph showing the spectral irradiance. In FIG. 13, the horizontal axis is the wavelength of light and the vertical axis is the spectral irradiance. FIG. 13 shows the result of calculating the amount of heat applied to the irradiated surface after calculating the energy intensity of the sky with respect to the irradiated surface by simulation based on the above-mentioned Example 1. In addition, FIG. 13 is an example of calculating the amount of heat received by the irradiation surface arranged on Miyakojima from 12:00 to 1300 on June 20, 2016. According to this embodiment, the integrated value of the energy applied to the irradiated surface is found to be 1,029.8 [W / m ² ], and the amount of heat received by the irradiated surface is 3,707,358 [J / m]. ² ] is required.
According to this embodiment, it is possible to predict the amount of irradiation heat received by high-rise structures and forests, which were difficult to measure, and it can be used for defense design of structures and forest planting plans.

<Calculation of the amount of irradiation applied to the structure>
In this embodiment, in the configuration shown in FIG. 1, the solar ray information providing system 10 is the material to be irradiated (the material of the irradiation material having the irradiation surface) from the amount of heat received by the irradiation surface, which is the result obtained in Example 3. ) Can be predicted. In this embodiment, the temperature rise prediction of the irradiation surface will be described. FIG. 14 is a diagram showing a trial calculation condition regarding a temperature rise of the material to be irradiated. As shown in FIG. 14, in this embodiment, it is assumed that the sun's rays on the irradiation surface J2 of the irradiation material J1 are incident, and the reflectance of the irradiation surface J2 is 30%. Further, it is assumed that the heat radiation from the irradiation material J1 is zero. Further, it is assumed that the heat transfer and heat conduction from the irradiation material J1 are zero.

FIG. 15 is a diagram showing a trial calculation example of a temperature rise after 1 hour depending on the material. When a sun ray having a calorific value of 3,707,358 [J / m ² ] is incident on the irradiation material J1 having a reflectance of the irradiation surface J2 of 30%, the amount of heat reflected on the irradiation surface J2 is 1,112,207. It is [J / m ² ], and the amount of heat absorbed by the irradiation material J1 is 2,595,151 [J / m ² ]. Considering the thermal characteristics of each material shown in FIG. 15, as shown in FIG. 15, the temperature rise after 1 hour for each material can be estimated. For example, if the material of the irradiation member J1 is steel, since heat capacity is 18864 [J / K], the amount of heat experienced 1 hour, 2595.151 [J / m2] × 1 [m 2] / 18864 [ J / K] = 137.6 [K]. Therefore, the temperature of the steel material at 20 [° C.] initially rises to 20 [° C.] + 137.6 [K] = 157.6 [° C.] after 1 hour. Similarly, the temperature of the glass wool heat insulating plate at 20 [° C.] initially rises to 20 [° C.] + 2545.5 [K] = 2576.5 [° C.]. Here, it is assumed that the shape of the material model of the irradiation material J1 is 1 mx 1 mx thickness 5 mm. Further, this trial calculation is based on the assumption that there is no heat dissipation (heat radiation, heat conduction, heat transfer, etc.) from the irradiation material J1. In reality, since there is heat dissipation from the irradiation material J1, the temperature does not rise so much. In the trial calculation, heat dissipation may be considered as necessary. This trial calculation makes it possible to predict the temperature rise in structures that were difficult to measure due to high places and people not approaching, and on the irradiated surface such as land.According to this embodiment, it is possible to predict the deterioration of structures and , Can be used for forest planting plans.

The reflectance of the grassland can be determined, for example, by the method described with reference to FIGS. 7 (a) and 7 (b). FIG. 17A is a graph showing an example of the spectral irradiation intensity from each direction on the grassland. In FIG. 17A, the horizontal axis is the wavelength of light and the vertical axis is the irradiation intensity. FIG. 17B is a graph showing an example of spectral reflectance in grassland. In FIG. 17B, the horizontal axis is the wavelength of light and the vertical axis is the spectral reflectance. With reference to FIG. 17B, it can be seen that the spectral reflectance of the grassland is 5 to 10%. Further, referring to FIG. 17B, it can be seen that the reflectance in the grassland increases rapidly in the near infrared.
