Description

[Technical field]

[0001] The present invention relates to a forecast information providing system and a forecast information providing program. [Background technology]

[0002] Recently, the effects of sunlight (e.g., ultraviolet light, visible light, and infrared light) on the human body and living environment have become known, and attention has begun to be paid to the amount of sunlight exposure (e.g., ultraviolet light exposure and solar radiation). For example, in the exposure amount estimation system described in Japanese Patent No. 5524741, location information indicating a location and environmental information indicating the amount of an exposure target such as ultraviolet light present at the location are stored in an environmental information storage unit in association with each other, and the exposure amount is estimated based on the environmental information acquired from the environmental information storage unit and an exposure rate determined according to the user's behavior, etc., and the estimated exposure amount is provided to the user. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5524741 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the exposure estimation system described in Patent No. 5524741 estimates the amount of exposure using environmental information (pollen dispersion amount, ultraviolet radiation amount, aerosol amount) identified by location information stored in an environmental information storage unit. However, there is a problem in that the environmental information identified by this location information does not allow the user receiving the information to easily obtain more detailed information.

[0005] For example, in the real world, the parts and places where one wishes to know the energy intensity of ultraviolet radiation, solar radiation, etc. are not necessarily limited to horizontal planes or planes perpendicular to the sun's rays, but are various. In order to know the energy intensity of such various parts and places, it is conceivable to calculate the energy intensity on the actual irradiated surface from the energy intensity on the horizontal plane or perpendicular to the sun's rays using trigonometric functions, etc. However, since the energy intensity from the real sky scattered and reflected by atmospheric components differs for each direction, there is a problem that calculations using trigonometric functions, etc., cannot obtain sufficient accuracy.

[0006] In addition, it is known that sunlight affects the exterior coating of buildings. For this reason, there is a demand for predicting the effect of sunlight on exterior coating, but no system for predicting the effect of sunlight on exterior coating has been provided so far.

[0007] The present invention has been made to solve the above-mentioned problems, and has an object to provide a prediction information providing system for predicting the effect of sunlight on exterior paint. [Means for solving the problem]

[0008] In order to solve the above problem, the present invention includes a storage unit that stores date and time information, which is information on a date and time, location information, which is information on a location, and sunlight ray intensity information, which is information on a date and time and a location indicated by the location information, in association with each other; a communication unit that performs communication; a first calculation unit that calculates the sunlight ray intensity information associated with sunlight ray inquiry information included in prediction information inquiry information input via the communication unit; a second calculation unit that calculates direction specific sunlight ray intensity information using a calculation result of the first calculation unit; and a third calculation unit that calculates prediction information that predicts an influence of sunlight on an exterior coating indicated by exterior coating type information included in the prediction information inquiry information input via the communication unit, using a calculation result of the second calculation unit, wherein the sunlight ray inquiry information includes the date and time information, the location information, direction information indicating a direction in which an irradiation surface that is irradiated with sunlight faces, The spectral intensity,the direction-specific sunlight ray intensity information is information including an intensity of sunlight ray received by an irradiation surface indicated by the direction information at a date and time indicated by the date and time information and at a location indicated by the location information, The third calculation unit calculates prediction information for predicting an effect of sunlight on the exterior coating according to the spectral intensity, The communication unit transmits the prediction information calculated by the third calculation unit to a sender of the prediction information inquiry information. Effect of the Invention

[0009] According to the present invention, it is possible to provide a prediction information providing system and a prediction information providing program for predicting the effect of sunlight on exterior paint. [Brief description of the drawings]

Therefore, the description of the embodiments shown below does not limit the content of the invention described in the claims.

[0012] In the following embodiment, the present invention is applied to a forecast information providing system to provide a user with information on sunlight, such as the amount of solar radiation, but the present invention may also provide a user with individual information on ultraviolet rays, infrared rays, visible light, or other electromagnetic waves contained in sunlight. In the following embodiment, the intensity of sunlight is also referred to as solar radiation intensity. EXAMPLES

[0013] 1 is a block diagram showing a configuration of a prediction information providing system according to a first embodiment of the present invention. A prediction information providing system 10 of the present embodiment is, for example, a server machine made up of a computer.

[0014] As shown in Fig. 1, the forecast information providing system 10 includes a storage unit 13 that stores sunlight ray intensity information 16 and other various information, which will be described later in detail, a communication unit 17 that performs communication, a first calculation unit 11 that calculates sunlight ray intensity information 16 associated with sunlight ray inquiry information included in forecast information inquiry information received via the communication unit 17, a second calculation unit 12 that calculates direction-specific sunlight ray intensity information using the calculation result of the first calculation unit 11, and a third calculation unit 21 that calculates forecast information that predicts the influence of sunlight on the exterior coating indicated by the exterior coating type information included in the forecast information inquiry information input via the communication unit 17, using the calculation result of the second calculation unit 12. The communication unit 17 communicates with, for example, the outside. The forecast information inquiry information includes sunlight ray inquiry information and exterior coating type information. The sunlight ray inquiry information includes date and time information 14, location information 15, and direction information 16a that indicates the direction in which the irradiated surface that receives sunlight ray irradiation, i.e., solar radiation, faces. The direction-specific sunlight intensity information is the intensity of sunlight received by the irradiated surface indicated by the direction information 16a at the date and time indicated by the date and time information 14 and the location indicated by the location information 15, and the communication unit 17 transmits the prediction information calculated by the third calculation unit 21 to the sender of the prediction information inquiry information. Each component shown in FIG. 1 may be configured with hardware. Also, each component shown in FIG. 1 may be realized by the prediction information providing system 10 executing a program, and the storage unit 13 may store the program executed by the prediction information providing system 10. The storage unit 13 has a volatile storage device or a non-volatile storage device depending on the use of the data.

[0015] The communication unit 17 may be configured to transmit direction specific solar ray intensity information indicating the direction specific solar ray intensity calculated by the second calculation unit 12 to the sender of the forecast information inquiry information.

[0016] In addition, in the forecast information providing system 10, the communication unit 17 may be configured to transmit the sunlight beam intensity information calculated by the first calculation unit 11 to the sender of the forecast information inquiry information. In this case, the client machine 2 or 3 may have a configuration corresponding to the function of the second calculation unit 12. That is, the present invention is a forecast information providing system in which a server machine and a client machine are connected via a network, and the server machine includes a storage unit 13 that stores date and time information 14, which is information related to date and time, location information 15, which is information related to a location, and sunlight beam intensity information 16, which is information related to the date and time indicated by the date and time information and the sunlight beam intensity at the location indicated by the location information, in association with each other, a first communication unit that communicates with the client machine, and a first calculation unit 11 that calculates the sunlight beam intensity information 16 associated with the sunlight beam inquiry information included in the forecast information inquiry information input via the first communication unit, The first communication unit transmits the sunlight ray intensity information 16 calculated by the first calculation unit 11 to the client machine, and the client machine includes a second communication unit that communicates with the server machine 1 and a second calculation unit (corresponding to the function of the second calculation unit 12) that calculates direction-specific sunlight ray intensity information using the sunlight ray intensity information 16 input through the second communication unit, and the second communication unit (corresponding to the function of the second calculation unit 12) transmits sunlight ray inquiry information to the server machine, and the sunlight ray inquiry information may include date and time information 14, the location information, and direction information 16a indicating the direction in which the irradiation surface that is irradiated with sunlight faces. The client machine and the server machine may be in the same terminal device without a network. In this case, the client machine and the server machine may be in the same device, or may be in a configuration in which the client machine and the server machine are connected by a bus, for example. When the client machine and the server machine are in the same device, connecting the client machine and the server machine may refer to data transfer between a program that realizes the function of the client machine and a program that realizes the function of the server machine via a memory or the like.

[0017] The memory unit 13 stores date and time information 14, which is information regarding date and time, location information 15, which is information regarding a location, and sunlight beam intensity information 16, which is information regarding the date and time indicated by the date and time information 14 and the intensity of sunlight at the location indicated by the location information 15, in association with each other.

[0018] A communication unit 17 of the prediction information providing system 10 is connected to a network 4 such as the Internet. Client machines 2 and 3 used by users are connected to the network 4, and the client machines 2 and 3 communicate with the prediction information providing system 10 via the network 4.

[0019] From the client machine 2 or 3, forecast information inquiry information is transmitted to the forecast information providing system 10 via the network 4. The forecast information inquiry information includes sunlight inquiry information and exterior coating type information. The sunlight inquiry information includes date and time information 14, location information 15, and direction information 16a indicating the direction in which the irradiated surface receiving the sunlight faces. The direction indicated by the direction information 16a is a direction perpendicular to the plane in which the irradiated surface receiving the sunlight spreads. The direction information 16a will be described later with reference to Figs. 2 to 5. The calculation result by the first calculation unit 11 is transmitted from the forecast information providing system 10 to the client machine 2 or 3, which is the sender of the forecast information inquiry information, via the network 4.

[0020] The first calculation unit 11 calculates sunlight ray intensity information 16, which will be described later in detail, using the date and time information and location information included in the sunlight ray inquiry information. The second calculation unit 12 calculates direction specific sunlight ray intensity information, which is information including the intensity of sunlight ray received by the irradiation surface indicated by the direction information 16a, using the calculation result by the first calculation unit 11. The communication unit 17 transmits the direction specific sunlight ray intensity information, which indicates the direction specific sunlight ray intensity calculated by the second calculation unit 12, via the network 4 to the client machine 2 or the client machine 3, which is the sender of the forecast information inquiry information.

[0021] 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's rays irradiated onto irradiation surface A, which is a surface parallel to the ground. FIG. 4 is a diagram for explaining the sun's rays irradiated onto irradiation surface B, which is a surface that forms an angle of 30° with the ground. FIG. 5 is a diagram for explaining the sun's rays irradiated onto irradiation surface C, which is a surface that forms an angle of 90° with the ground. In FIG. 3, FIG. 4, and FIG. 5, the direction in which the irradiation surface that receives the irradiation of the sun's rays faces, that is, the direction indicated by the direction information 16a, is described as the "direction of the irradiation surface."

[0022] As shown in Figure 2, the sunlight irradiating the earth includes direct solar radiation that is irradiated from the direction of the sun, as well as diffuse solar radiation that is irradiated from directions other than the direction of the sun. Diffuse solar radiation is irradiated onto the irradiated surface from the entire sky. Irradiated surface A, which is a surface parallel to the ground, is irradiated with both diffuse solar radiation and direct solar radiation from the entire sky, as shown in Figure 3.

[0023] Furthermore, for irradiated surface B, which forms an angle of 30° with the ground, diffuse solar radiation and direct solar radiation are irradiated from the direction of the sky in which irradiated surface B faces, as shown in Figure 4. For irradiated surface C, which forms an angle of 90° with the ground, as shown in Figure 5, the sun is facing the back side of irradiated surface C, so direct solar radiation is not irradiated, but diffuse solar radiation is irradiated from the direction of the sky in which irradiated surface C faces. In addition to the diffuse solar radiation and direct solar radiation that directly irradiates the irradiated surface, solar radiation that is reflected by the ground and then irradiated to the irradiated surface also exists.

[0024] 3, 4, and 5, the intensity of the irradiated sunlight varies greatly depending on the direction in which the irradiated surface faces. Therefore, in this embodiment, different direction-specific sunlight intensity information is calculated for each direction in which the irradiated surface faces, and this information is provided to the client machine 2 or the client machine 3 that is the sender of the forecast information inquiry information.

[0025] In this embodiment, in addition to the diffuse solar radiation and the direct solar radiation, the sunlight reflected by other irradiation surfaces such as the ground and a wall surface and irradiated onto the irradiation surface can also be taken into consideration. This point will be described with reference to Fig. 6. Fig. 6 is a diagram for explaining the sunlight reflected by the irradiation surface E and irradiated onto the irradiation surface D.

[0026] In an actual environment, the amount of sunlight received by the irradiated surface D includes not only the sunlight (direct sunlight and scattered sunlight) directly received by the irradiated surface D, but also sunlight (direct sunlight and scattered sunlight) reflected by other irradiated surfaces (irradiated surface E) such as the ground or a wall surface (reflected light). In this embodiment, the intensity of the sunlight received by the irradiated surface is increased by including the intensity of the reflected light reflected by these other irradiated surfaces in the intensity of the sunlight received by the irradiated surface, thereby further improving the accuracy of determining the intensity of the sunlight received by the irradiated surface.

[0027] Usually, the reflectance of the other irradiated surface is used to calculate the reflected light from the other irradiated surface. The reflectance of the material surface is generally calculated using the reflectance of a specific representative wavelength, but in order to calculate the energy intensity with high accuracy, it is preferable to use the spectral reflectance. Here, the method of calculating the spectral reflectance of the other irradiated surface will be explained with reference to FIG. 7.

[0028] FIG. 7 is a diagram for explaining an example of a method for determining the spectral reflectance of another irradiated surface, in which FIG. 7(a) is a diagram showing how the sunlight directly received by the irradiated surface E is measured, and FIG. 7(b) is a diagram showing how the reflected light by the irradiated surface E is measured. As shown in FIG. 7(a) and FIG. 7(b), a measuring device 50 is used here. The measuring device 50 is a measuring device that functions as a spectrophotometer. First, as shown in FIG. 7(a), the measuring device 50 is used to measure the spectral illuminance (spectral illuminance of the sunlight irradiating the irradiated surface E) from above the irradiated surface E, which is the other irradiated surface. The measuring device 50 is also used to measure the spectral illuminance reflected by the irradiated surface E (spectral illuminance of the sunlight reflected by the irradiated surface E). The spectral reflectance of the irradiated surface E is calculated by Equation 1 using the calculated spectral illuminance from above the irradiated surface E and the spectral illuminance reflected by the irradiated surface E.

number

[0029] Next, calculation of the irradiation energy received by the irradiated surface using the spectral reflectance obtained by Equation 1 will be described. Fig. 8 is a diagram for explaining the light that enters the irradiated surface out of the reflected light from another irradiated surface. Fig. 8 shows a case where the irradiated surface G, which is the other irradiated surface, is the ground, and takes into consideration the proportion of the reflected light from irradiated surface G that enters irradiated surface F. The energy of light that enters irradiated surface F from irradiated surface G (ground) can be calculated by Equation 2.

number

[0030] The irradiation energy received by the irradiation surface G in the formula 2 can be obtained, for example, by the method shown in FIG. 7(a). As the reflectance in the formula 2, for example, the spectral reflectance obtained by the formula 1 can be used. The area ratio H in the formula 2 can be obtained as described below with reference to FIG. 8. In FIG. 8, the angle θ according to the direction of the irradiation surface F determines the field area of ​​the ground (irradiation surface G) on the irradiation surface F. If the irradiation surface G is an ideal ground (horizontal), the angle θ that determines the field area of ​​the irradiation surface G, which is the ground, is geometrically the angle between the irradiation surface F and the horizontal direction. However, in reality, it is better to take into account the change in topography, or the fact that the more distant the position of the irradiation surface G from the irradiation surface F is, the less reflected light enters the irradiation surface F and the contribution degree is attenuated, and it is better to determine the angle θ according to the required accuracy.

[0031] The ratio of the visual field area of ​​the ground on the irradiated surface F to the hemispherical area of ​​the irradiated surface F is the area ratio H. In this embodiment, when calculating the irradiation energy received by the irradiated surface F, it is possible to calculate with higher accuracy by adding the energy entering the irradiated surface F calculated by Equation 2 to the irradiation energy due to the diffuse solar radiation and direct solar radiation directly irradiated to the irradiated surface F. Furthermore, although Equation 2 takes the ground into consideration as another irradiated surface, it is possible to calculate with higher accuracy the irradiation energy received by the irradiated surface F by considering not only the light reflected by the ground but also all other irradiated surfaces onto which the reflected light may enter the irradiated surface F.

[0032] FIG. 9 is a diagram showing an example of information stored in the storage unit 13 shown in FIG. 1. The storage unit 13 stores the information shown in FIG. 9 in, for example, a database format. The storage unit 13 stores date and time information 14 as a first primary key. The date and time information 14 may include the year, month, day, and time. The storage unit 13 stores location information 15 as a second primary key. The location information 15 is information that identifies a position on the earth using, for example, east longitude and north latitude.

[0033] The storage unit 13 stores the solar solid angle at the first primary key and the second primary key as the stored value of the solar ray intensity information 16. The storage unit 13 stores the direct solar radiation intensity at the first primary key and the second primary key as the stored value of the solar ray intensity information 16. The storage unit 13 stores the scattered solar radiation intensity at the first primary key and the second primary key as the stored value of the solar ray intensity information 16. The storage unit 13 stores the albedo value at the first primary key and the second primary key as the stored value of the solar ray intensity information 16. The albedo value is the ratio of the reflected solar ray intensity to the irradiated solar ray intensity. For example, in a certain area where the location information 15 is, when the date and time information 14 is summer, the ground is soil and the albedo value is low, and when the date and time information 14 is winter, the ground is snowy and the albedo value is high. The values ​​shown in FIG. 9 are, for example, collected and stored in the storage unit 13 as actual measurements. The direction information 16a included in the sunlight beam intensity information 16 is included in the stored values ​​shown in Fig. 9. The information included in the sunlight beam intensity information 16 includes, for example, a value calculated by solving the radiative transfer equation, or a value calculated in the process of solving the radiative transfer equation.

[0034] Fig. 10 is a flowchart showing the operation of the prediction information providing system 10 shown in Fig. 1. In step S71, it is determined whether or not prediction information inquiry information has been received from the client machine 2 or the client machine 3 via the network 4. If prediction information inquiry information has been received (step S71: Yes), the process proceeds to step S72, and if prediction information inquiry information has not been received (step S71: No), the process returns to step S71.

[0035] In step S72, based on the sunlight inquiry information included in the forecast information inquiry information received in step S71, sunlight intensity information 16 is calculated, which is information including the intensity of sunlight received at the location indicated by the location information 15 included in the sunlight inquiry information on the date and time indicated by the date and time information 14 included in the sunlight inquiry information, and stored in the storage unit 13. The sunlight intensity information 16 is calculated, for example, using a radiative transfer equation.

[0036] In step S73, a mathematical calculation is performed on the sunlight beam intensity information 16 calculated in step S72 using the direction information 16 as an input value to calculate direction-specific sunlight beam intensity information, which is sunlight beam intensity information received by the irradiated surface indicated by the direction information 16a at the date and time indicated by the date and time information 14, at the location indicated by the location information 15 included in the sunlight beam inquiry information.

[0037] In step S74, the direction-specific sunlight intensity information calculated in step S73 is used to calculate prediction information for predicting the influence of sunlight on the exterior coating indicated by the exterior coating type information included in the prediction information inquiry information received in step S71. The prediction information includes, for example, information on deterioration prediction, color fading prediction, heat insulation prediction, and temperature prediction of the exterior coating. The calculation of the prediction information will be described in detail later.

[0038] In step S75, the forecast information calculated in step S74 is transmitted via the network 4 to the client machine 2 or the client machine 3 which is the sender of the current forecast information inquiry information. The client machine 2 or the client machine 3 can obtain forecast information and easily obtain more detailed effects on the exterior paint by simply transmitting sunlight inquiry information including date and time information 14, location information 15, and direction information 16a and forecast information inquiry information including exterior paint type information to the forecast information providing system 10. The client machine 2 or the client machine 3 can provide various applications to end users by using the forecast information obtained from the forecast information providing system 10. EXAMPLES

[0045] Forecast information inquiry information is transmitted from the client machine 2 or the client machine 3 to the forecast information providing system 100 via the network 4. The sunlight inquiry information includes date and time information 114, location information 115, and direction information 116a. Direction-specific sunlight intensity information, which is the extraction result by the extraction unit 112, is transmitted from the forecast information providing system 100 via the network 4 to the client machine 2 or the client machine 3 that is the sender of the forecast information inquiry information.

[0046] In this embodiment, an example of information stored in the storage unit 113 is the information shown in FIG.

[0047] Fig. 12 is a flowchart showing the operation of the forecast information providing system 100 shown in Fig. 11. In step S91, information included in the sunlight beam intensity information 116 for all locations at all dates and times is calculated using date and time information and location information. For example, a radiative transfer equation is used to calculate the information included in the sunlight beam intensity information 116. That is, the information included in the sunlight beam intensity information 116 includes, for example, a value calculated by solving the radiative transfer equation, or a value calculated in the process of solving the radiative transfer equation. In step S92, the information included in the sunlight beam intensity information 116 calculated in step S91 is stored in the storage unit 113.

[0048] Next, if forecast information inquiry information is received from the client machine 2 or 3 via the network 4 (step S93: Yes), the process proceeds to step S94, and if forecast information inquiry information is not received (step S93: No), the process returns to step S90. The forecast information inquiry information includes sunlight ray inquiry information. Note that the calculation of the information included in the sunlight ray intensity information 116 and the storage of the calculated information in the storage unit 13 may be completed before the process of receiving the sunlight ray inquiry information from the client machine 2 or 3 is performed, or the calculation may be updated each time data for a region that was previously unavailable becomes available, for example.

[0049] In step S94, sunlight ray intensity information 116 is extracted from storage unit 113 based on sunlight ray inquiry information included in the data received from client machine 2 or client machine 3. That is, sunlight ray intensity information 116 corresponding to date / time information 114 and location information 115 included in the sunlight ray inquiry information is extracted from storage unit 113. In step S94, a mathematical calculation is further performed on the value of the extracted sunlight ray intensity information 116 using direction information 116a as an input value to calculate direction-specific sunlight ray intensity information, which is information including the intensity of sunlight received by the irradiated surface indicated by direction information 116a at the date / time indicated by date / time information 14, at the location indicated by location information 15 included in the sunlight ray inquiry information.

[0050] In step S95, the direction-specific sunlight intensity information calculated in step S94 is used to calculate prediction information for predicting the influence of sunlight on the exterior coating indicated by the exterior coating type information included in the prediction information inquiry information received in step S93. The prediction information includes, for example, information on deterioration prediction, color fading prediction, heat insulation prediction, and temperature prediction of the exterior coating. The calculation of the prediction information will be described in detail later.

[0051] In step S96, the prediction information calculated in step S95 is transmitted via the network 4 to the client machine 2 or the client machine 3 which is the sender of the current prediction information inquiry information. The client machine 2 or the client machine 3 can obtain prediction information and easily obtain more detailed information about the impact on the exterior paint simply by transmitting sunlight inquiry information including date and time information 14, location information 15, and direction information 16a and prediction information inquiry information including exterior paint type information to the prediction information providing system 100. The client machine 2 or the client machine 3 can provide various applications to end users by using the prediction information obtained from the prediction information providing system 100.

[0052] Furthermore, in this embodiment, the sunlight beam intensity information 116 is calculated in advance, so that the response is quicker and direction-specific sunlight beam intensity information can be provided with higher immediacy than when the sunlight beam intensity information 116 is calculated after receiving sunlight beam inquiry information from the client machine 2 or the client machine 3. EXAMPLES

[0053] <Calculation of radiation heat amount> In this embodiment, in the configuration shown in FIG. 1, the predictive information providing system 10 can calculate the amount of irradiated heat. FIG. 13 is a graph showing 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 irradiated 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 embodiment 1. FIG. 13 also shows an example of calculation of the amount of heat received by an irradiated surface placed in Miyakojima from 12:00 to 13:00 on June 20, 2016. According to this embodiment, the integrated value of the energy irradiated to the irradiated surface is 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 heat radiation received by high-rise structures and forests, which have been difficult to measure, and this can be utilized in the defense design of structures and forest plantation planning. EXAMPLES

[0054] <Calculation of the amount of radiation irradiated to a structure> In this embodiment, in the configuration shown in FIG. 1, the prediction information providing system 10 can predict the temperature rise according to the irradiated material (the material of the irradiated material having the irradiated surface) from the amount of heat received by the irradiated surface, which is the result obtained in Example 3. In this embodiment, the prediction of the temperature rise of the irradiated surface will be described. FIG. 14 is a diagram showing the calculation conditions for the temperature rise of the irradiated material. As shown in FIG. 14, in this embodiment, it is assumed that sunlight is incident on the irradiated surface J2 of the irradiated material J1, and the reflectance of the irradiated surface J2 is 30%. It is also assumed that the thermal radiation from the irradiated material J1 is zero. It is also assumed that the heat transfer and heat conduction from the irradiated material J1 are zero.

[0055] Fig. 15 shows an example of the estimated temperature rise after one hour depending on the material. 2 When the solar radiation of heat of 1,112,207 [J / m 2 ], and the heat absorbed by the irradiated material J1 is 2,595,151 [J / m 2 Considering the thermal characteristics of each material shown in Figure 15, it is possible to estimate the temperature rise for each material after one hour, as shown in Figure 15. For example, if the material of irradiated material J1 is steel, the heat capacity is 18864 [J / K], so the amount of heat received in one hour is 2595.151 [J / m2] × 1 [m 2] / 18864[J / K]=137.6[K]. Therefore, the temperature of the steel, which is initially 20[℃], will rise to 20[℃]+137.6[K]=157.6[℃] after one hour. Similarly, the temperature of the glass wool insulation plate, which is initially 20[℃], will rise to 20[℃]+25745.5[K]=25765.5[℃]. Note that the shape of the material model of the irradiated material J1 is 1mx1mx5mm thick. This calculation is based on the assumption that there is no heat radiation (thermal radiation, thermal conduction, thermal transfer, etc.) from the irradiated material J1. In reality, there is heat radiation from the irradiated material J1, so the temperature does not rise this much. Heat radiation can be taken into account in the calculation as necessary. This trial calculation makes it possible to predict temperature rises on irradiated surfaces such as structures and land that are difficult to measure because they are located at high places or inaccessible to humans. According to this embodiment, this can be used to predict deterioration of structures and for forest reforestation planning. EXAMPLES

FIG. 16(a) is a graph showing an example of the spectral irradiation intensity from each direction on the sidewalk.

FIG. 16(b) is a graph showing an example of the spectral reflectance on the sidewalk. In FIG. 16(b), the horizontal axis is the wavelength of light, and the vertical axis is the spectral reflectance. Referring to FIG. 16(b), it can be seen that the spectral reflectance of the sidewalk is 10 to 20%. EXAMPLES

[0057] <Inclusion of reflections from other irradiated surfaces (e.g. grass)> In this embodiment, in the configuration shown in FIG. 1, the forecast information providing system 10 can calculate the reflected energy based on the reflectance of the grassland and calculate the amount of irradiation irradiated to the irradiation surface. The reflectance of the grassland can be obtained, for example, by the method described with reference to FIG. 7(a) and FIG. 7(b). FIG. 17(a) is a graph showing an example of the spectral irradiation intensity from each direction on the grassland. In FIG. 17(a), the horizontal axis is the wavelength of light, and the vertical axis is the irradiation intensity. FIG. 17(b) is a graph showing an example of the spectral reflectance on the grassland. In FIG. 17(b), the horizontal axis is the wavelength of light, and the vertical axis is the spectral reflectance. Referring to FIG. 17(b), it can be seen that the spectral reflectance of the grassland is 5 to 10%. Also, referring to FIG. 17(b), it can be seen that the reflectance of the grassland increases sharply in the near infrared. EXAMPLES

[0058] <Inclusion of reflections from other irradiated surfaces (example: asphalt)> In this embodiment, in the configuration shown in FIG. 1, the prediction information providing system 10 can calculate the reflected energy based on the reflectance of the asphalt and calculate the amount of irradiation irradiated to the irradiation surface. The reflectance of the asphalt can be obtained, for example, by the method described with reference to FIG. 7(a) and FIG. 7(b). FIG. 18(a) is a graph showing an example of the spectral irradiation intensity from each direction on asphalt. In FIG. 18(a), the horizontal axis is the wavelength of light, and the vertical axis is the irradiation intensity. FIG. 18(b) is a graph showing an example of the spectral reflectance on asphalt. In FIG. 18(b), the horizontal axis is the wavelength of light, and the vertical axis is the spectral reflectance. Referring to FIG. 18(b), it can be seen that the spectral reflectance of asphalt is 5%. EXAMPLES

[0060] (Deterioration and fading prediction) The predictive information system generates the relevant spectral intensity data (spectral intensity data consists of direct light components and scattered light components) according to the location, date and time, direction, and spectral intensity. From the generated spectral intensity data, the predictive information system integrates the energy intensity of wavelengths corresponding to the dissociation energy of specific chemical bonds that make up the exterior paint over a desired period. From the integrated value over a period, the predictive information system predicts the deterioration and fading of the exterior paint over a period.

[0061] The prediction information providing system accepts input of exterior paint type, location, date and time, direction, and period included in the prediction information inquiry information, and obtains prediction information on deterioration and fading of the exterior paint according to the period.

This information may be input each time, or may be stored in advance.

FIG. 19(A) is a diagram showing the relationship between the wavelength and energy of light. FIG. 19(B) is a diagram showing bond dissociation energy of chemical bonds. The above-mentioned third calculation unit can calculate prediction information by using the relationships shown in FIG. 19(A) and FIG. 19(B).

[0064] (About heat insulation prediction) The predictive information system generates the spectral intensity data according to the location, date and time, direction, and spectral intensity. From the generated spectral intensity data, the predictive information system calculates the spectral reflectance reflected outside the exterior paint according to the spectral reflectance (color) of the exterior paint (mainly roofs) that has been measured in advance. The predictive information system integrates the spectral reflectance (spectral energy) according to the date and time to predict the heat blocking amount (heat blocking effect). The spectral reflectance uses the spectral reflectance of a reflection model according to the reflective surface. For example, for a polished painted board, it is composed of a specular reflection model and a diffuse reflection model. In this case, specular spectral reflectance is used for the direct light component, and diffuse spectral reflectance is used for the scattered light component. Other reflection models such as BRDF can also be used.

[0066] The period integrated value, which is the integrated value of the heat shielding effect (heat shielding energy) in the heat shielding prediction, can be calculated by the formula shown in FIG.

[0067] (Regarding temperature prediction) The predictive information system generates the spectral intensity data according to the location, date and time, direction and spectral intensity. From the generated spectral intensity data, the predictive information system calculates the spectral transmittance that penetrates into the exterior paint according to the spectral reflectance (color) of the exterior paint (mainly the roof) that has been measured in advance. The predictive information system integrates the spectral transmittance (spectral energy) according to the date and time, and predicts the heat energy that penetrates into the exterior paint and the surface and internal temperatures of the painted components.

[0068] The prediction information provision system accepts input of the type of exterior paint, location, date and time, and direction contained in the prediction information inquiry information, and obtains prediction information for the heat energy penetrating into the exterior paint according to the date and time.

[0069] The amount of heat received by the exterior paint in temperature prediction can be calculated using the formula shown in Figure 21. The amount of heat received by the object surface from the outside in temperature prediction can be calculated using the formula shown in Figure 22.
