Description

[Technical Field]

[0001] The present invention relates to a deterioration prediction device, a deterioration prediction system, a program, and a deterioration prediction method. [Background technology]

[0002] Patent Documents 1 and 2 disclose a home maintenance system.

[0003] The home maintenance system disclosed in Patent Document 1 calculates a first deterioration prediction line that represents the progression of exterior material deterioration due to aging based on the service life of the exterior material and the climatic conditions of the construction site. This home maintenance system calculates a second deterioration prediction line that represents the progression of exterior material deterioration due to a disaster based on disaster prediction information. This home maintenance system calculates the maintenance timing for the exterior material that corresponds to the deterioration tolerance based on the first deterioration prediction line and the second deterioration prediction line. The first deterioration prediction line calculated by this home maintenance system reflects climatic conditions, but it is unclear how these climatic conditions were actually measured and collected. Therefore, the maintenance timing calculated by this home maintenance system does not reflect the effect of actual solar radiation on the home on the deterioration of the exterior material.

[0004] The home maintenance system disclosed in Patent Document 2 calculates the degree of deterioration of roofing materials based on the results of an assessment of the environmental conditions of the building's construction site, in accordance with their age-related deterioration. This home maintenance system calculates the maintenance timing for the roofing materials based on the calculated degree of deterioration, the useful life of the roofing materials, and the roofing material's deterioration tolerance. Because the assessment results of actual environmental conditions change periodically, this home maintenance system recalculates the maintenance timing for the roofing materials at regular intervals. The degree of deterioration calculated by this home maintenance system reflects the assessment results of the environmental conditions of the building's construction site, but it is unclear how these environmental conditions were actually measured and collected. Therefore, the maintenance timing calculated by this home maintenance system does not reflect the impact of actual solar radiation on the house on the deterioration of exterior materials.

[0026] Hereinafter, embodiments will be described with reference to the drawings. Features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples in the drawings.

[0027] In the following description, when ordinal numbers such as "first" and "second" are used in conjunction with common names, the ordinal numbers are used only to identify the objects to which they are attached. They do not limit the objects to which they are attached to any particular objects, and they do not specify the order, rank, order, hierarchy, priority, or subordination of the objects to which they are attached.

[0028] <Outline of the deterioration prediction system> Figure 1 is a block diagram showing the overall configuration of a deterioration prediction system 1. The deterioration prediction system 1 is a system that predicts the deterioration of the exterior materials of each house 92. The deterioration prediction system 1 is a system that allows information about the deterioration of a certain exterior material of a certain house 92 to be shared among multiple houses 92 that use the same type of exterior material as that particular exterior material.

[0029] Houses 92 exist all over Japan. Houses 92 are built facing various directions. The exterior of each house 92 is finished with exterior materials such as roofing materials, exterior wall materials, roofing and sealing. Houses 92 are owned, used, or lived in by user 91. Hereinafter, a house 92 owned, used, or lived in by user 91 will be referred to as user 91's house 92. Houses 92 may be either new or second-hand. The construction company of houses 92 does not matter. For example, all houses 92 may be constructed by the same contractor, or some houses 92 may be constructed by different contractors.

[0030] The deterioration prediction system 1 includes a deterioration prediction device 20, a storage device 40, a number of terminal devices 10, a number of imaging devices 11, a number of solar panels 61, a number of power meters 62, and a number of power management devices 63.

[0031] <Solar panels> The solar panels 61 are installed on the roofs of the houses 92. The solar panels 61 generate electricity from solar energy. The solar panels 61 output the generated electricity to a power distributor of the house 92 via a power conditioner and a power meter 62. As a result, the electricity generated by the solar panels 61 is consumed within the house 92, and any surplus electricity that is not consumed is reverse-flowed to the power lines or stored in a battery.

[0032] <Power meter> A power meter 62 is installed in each of the houses 92. The power meter 62 periodically measures the power generated by the solar panels 61 at very short intervals, and outputs the measured power value to the power management device 63 each time a measurement is taken.

[0033] <Power management device> The power management device 63 is composed of a dedicated computer system. The dedicated computer system is a computer system that is installed on an interior wall of the residence 92 or the like and has the function of monitoring or controlling the electrical appliances in the residence 92. For example, a dedicated computer system may be a HEMS (Home Energy Management System) controller. The electrical appliances may be, for example, air conditioners, lighting fixtures, water heaters, refrigerators, televisions, household electrical appliances, communication devices, solar power generators, or power storage devices. Monitoring of electrical appliances may include, for example, monitoring the status of the electrical appliances, monitoring or integrating the power consumption of the electrical appliances, and monitoring or integrating the power generated by the electrical appliances.

[0034] Every time the power management device 63 receives a power measurement value from the power meter 62, it stores the power measurement value in association with the measurement time. In this way, the power management device 63 accumulates time-series data of the power measurement value. The measurement time is the time when the power measurement value is input to the power management device 63.

[0035] The power management device 63 is connected to a communication network 30 such as the Internet. Every time the power management device 63 receives a power measurement value from the power meter 62, it transmits the power measurement value and the measurement time to the deterioration prediction device 20 via the communication network 30.

[0036] <Terminal device and imaging device> The terminal devices 10 are used by users 91. The terminal devices 10 may be built into a remote controller that controls electrical appliances in a home 92 wirelessly or via a wired connection. The terminal devices 10 are configured as general-purpose computer systems or dedicated computer systems. A general-purpose computer system refers to a computer system, such as a mobile phone, smartphone, tablet computer, laptop computer, or desktop computer, on which a general-purpose operating system (OS) is installed. Examples of general-purpose OSs include Windows (registered trademark), Android (registered trademark), iOS (registered trademark), macOS (registered trademark), Linux (registered trademark), or Unix (registered trademark). When the terminal devices 10 are configured as dedicated computer systems such as a HEMS, the terminal devices 10 may have the same functions as the power management device 63. In this case, the power management device 63 does not need to be installed in the home 92.

[0037] The terminal device 10 has a display device. The terminal device 10 displays various information on the display device. The terminal device 10 has input devices such as a touch panel, push buttons, keys, a keyboard, a mouse, a touchpad, a star, and a pointing device. When the user 91 operates the input device, the terminal device 10 receives commands and information corresponding to the operation.

[0038] The terminal device 10 has a communication device such as a mobile phone line communication module, a network card, and a WiFi (registered trademark) adapter. The terminal device 10 is connected to a communication network 30 such as the Internet by the communication device. The terminal device 10 can access the deterioration prediction device 20 through the communication network 30. For example, a secure communication protocol such as a VPN (Virtual Private Network) may be adopted for communication between the terminal device 10 and the deterioration prediction device 20.

[0039] An application program such as an internet browser and a viewing program is installed in the terminal device 10. By executing the application program, the terminal device 10 accesses the deterioration prediction device 20 via the communication network 30, logs in to the deterioration prediction device 20 based on a user ID (identifier) ​​and password, provides information to the deterioration prediction device 20, receives information from the deterioration prediction device 20, and displays the contents of the provided information on a display device. A user ID is assigned to each user 91. Each user ID is a unique value. The user ID is associated with one of the residences 92, and is also associated with the power management device 63, power meter 62, and power management device 63 of that residence 92.

[0040] The terminal device 10 is connected to an imaging device 11. The imaging device 11 captures an image of a subject and generates an image of the subject. The terminal device 10 stores the image generated by the imaging device 11.

[0041] The imaging device 11 may be built into the terminal device 10, or may be externally attached to the terminal device 10 via a wired or wireless connection. The imaging device 11 may be portable or stationary. The imaging device 11 may be carried by the user 91 together with the terminal device 10. The imaging device 11 may be installed on the exterior of the house 92. The imaging device 11 may be a security camera or a fixed camera installed outside the house 92. The imaging device 11 may be mounted on an aircraft such as a multicopter that flies near the house 92. In this case, it is preferable that the aircraft be capable of hovering. The imaging device 11 may be installed outside the house 92 so as to face the exterior material of the house 92. The imaging device 11 may be installed on the exterior wall or roof of a house across from the house 92 so as to face the exterior material of the house 92. The more pixels the imaging device 11 has, the better.

[0042] The terminal device 10 stores an actual image 13 showing the exterior materials of the house 92. The actual image 13 is used when providing information about deterioration of the exterior materials of the house 92.

[0043] The actual image 13 may be captured by the imaging device 11 and recorded in the terminal device 10. The actual image 13 may be captured by an imaging device other than the imaging device 11 and recorded in the terminal device 10. The actual image 13 may be automatically captured by the imaging device 11 by the terminal device 10 automatically controlling the imaging device 11, and recorded in the terminal device 10. The timing of capturing the actual image 13 is not important, and the actual image 13 may be captured in advance or in real time. It is preferable that the actual image 13 is as recent as possible and that the time of capturing the actual image 13 is close to the time of use of the actual image 13. The time of capturing the actual image 13 may be any of morning, noon, evening, and night. The exterior material captured in the actual image 13 may be illuminated by an illuminator such as a flash, or may be exposed to natural light such as sunlight on a sunny or cloudy day.

[0044] The actual image 13 may have metadata such as Exif (Exchangeable image file format), etc. The metadata may include, for example, shooting date and time information, location information, shooting direction information, information on the manufacturer name of the terminal device 10 or the imaging device 11, information on the make and model name of the terminal device 10 or the imaging device 11, the resolution of the actual image 13, the horizontal resolution per unit of the actual image 12, the vertical resolution per unit of the actual image 13, and information on the shooting conditions of the actual image 13. The shooting conditions of the actual image 13 refer to conditions such as the shutter speed, aperture, ISO sensitivity, metering mode, whether or not a flash was used, exposure correction step value, focal length, and color space.

[0045] <Deterioration prediction device> The deterioration prediction device 20 is managed by an administrator 94. The administrator 94 may or may not be the builder of the house 92.

[0046] The deterioration prediction device 20 is a server or a host machine configured by a computer system, and may be a cloud computing system.

[0047] FIG. 2 is a block diagram of the deterioration prediction device 20. As shown in FIG. The deterioration prediction device 20 includes a computer 21, a storage device 22, an input device 24, a display device 26, and a communication device 28.

[0048] The computer 21 is responsible for overall control of the deterioration prediction device 20 and has a timekeeping function for measuring time and recognizing the current time. The computer 21 includes a main board, one or more hardware processors, a GPU (Graphics Processing Unit), and RAM (Random Access Memory). The main board includes a bus, a bus controller, an interface circuit, and the like, and transmits information between the hardware processor, GPU, RAM, storage device 22, input device 24, display device 26, and communication device 28. The hardware processor may be, for example, a CPU (Central Processing Unit). The hardware processor performs various types of arithmetic processing. The RAM provides the hardware processor with a storage area or a working area when the hardware processor performs arithmetic processing. The GPU performs processing that can be performed faster than the hardware processor (e.g., image processing and matrix calculation processing) under the command of the hardware processor.

[0049] The input device 24 is an input device such as a keyboard, a mouse, a touch panel, a touch pad, a stare, a pointing device, a key, a push button, etc. The input device 24 outputs a signal to the computer 21 according to the content of the operation performed by the administrator 94 on the input device 24. The computer 21 recognizes the input and command by the administrator 94 according to the signal transferred from the input device 24.

[0050] The display device 26 may be, for example, a liquid crystal display device or an organic EL display device. The display device 26 displays an image according to a video signal input from the computer 21.

[0051] The communicator 28 may be, for example, a network card or a Wi-Fi (registered trademark) adapter. The communicator 28 is connected to a communication network 30 via a router or the like.

[0052] The storage device 22 may be a memory device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive). An OS (Operating System) is stored in the storage device 22, and the OS is installed in the deterioration prediction device 20 so as to be executed by the computer 21. The storage device 22 stores a program 23 that can be executed on the OS by the computer 21, particularly the hardware processor.

[0053] <Storage device> The storage device 40 is a semiconductor storage device, a magnetic storage device, a NAS (Network Attached Storage), a data server, a file server, or a cloud computing system. The computer 21 of the deterioration prediction device 20 records information in the storage device 40 and reads information recorded in the storage device 40. The storage device 40 may be connected to the computer 21 via an interface circuit, or may be accessed by the computer 21 via the communication network 30.

[0054] The storage device 40 is a semiconductor storage device, a magnetic storage device, a NAS (Network Attached Storage), a data server, a file server, or a cloud computing system. The computer 21 of the deterioration prediction device 20 records information in the storage device 40 and reads information recorded in the storage device 40.

[0055] The storage device 40 stores various types of data used when the computer 21 executes the program 23. The storage device 40 stores data calculated by the computer 21. The data stored in the storage device 40 will be described in detail below.

[0056] The storage device 40 stores encrypted verification data 41 that associates a genuine user ID with a password for each user 91. Each user 91 can log in using the user ID and password.

[0057] The storage device 40 stores point data 42 for each user 91. The point data 42 is prepared for each user ID, and therefore each point data 42 is associated with a user ID. The point data 42 represents points that can be converted into cash and have economic value. The higher the value of the point data 42, the higher the economic value of the points.

[0058] The storage device 40 stores characteristic list data 44. As shown in FIG. 3 , the characteristic list data 44 is a list consisting of a type ID, a type coefficient, and a permissible deterioration level for each type of exterior packaging material. The type ID, the type coefficient, and the permissible deterioration level are associated with each type of exterior packaging material. A type ID is assigned to each type of exterior packaging material. Each type ID is a unique value, and the type of exterior packaging material is identified by its assigned type ID. The type coefficient is a coefficient determined by the type and material of the exterior packaging material. The type coefficient specifies the influence of the type and material of the exterior packaging material on the deterioration of the exterior packaging material. The type coefficient is determined through prior verification, such as experiments or simulations. The permissible deterioration level is the maximum deterioration level that the exterior packaging material can withstand. If the deterioration level of the exterior packaging material exceeds the permissible deterioration level, the life of the exterior packaging material will end. The permissible deterioration level is determined through prior verification, such as experiments or simulations. The deterioration level of the exterior packaging material is an index representing the degree of deterioration of the exterior packaging material. The deterioration level is a value greater than or equal to zero. If the exterior material is not deteriorating, the degree of deterioration of that exterior material is zero. The more deteriorating the exterior material, the higher the degree of deterioration of that exterior material. The degree of deterioration and the allowable degree of deterioration may be expressed as a percentage or as a score based on the percentage.

[0059] The storage device 40 stores exterior material list data 45 for each user 91. Because the exterior material list data 45 is prepared for each user ID, each exterior material list data 45 is associated with a user ID. The exterior material list data 45 lists the exterior materials used for the user 91's residence 92. Specifically, as shown in FIG. 4, the exterior material list data 45 consists of one or more items, each of which is composed of a component number, a type ID, and an installation coefficient. The component number, type ID, and installation coefficient are associated with each other for each item. Each component number is a unique value. The component number is assigned to the exterior material of the user 91's residence 92. The component number identifies the exterior material of the user 91's residence 92. The type ID identifies the type of exterior material of the user 91's residence 92. The installation coefficient is a coefficient determined from the installation location and installation direction of the exterior material of the user 91's residence 92 and the location conditions of the residence 92. The installation coefficient is used to predict the deterioration of exterior materials of a user 91's house 92. The installation coefficient specifies the effect that the installation location and installation direction of the exterior material have on the deterioration of the exterior material. The installation coefficient is determined through prior verification, for example, experiments or simulations. Note that if the installation location and installation direction of the exterior material change, the way sunlight enters the exterior material also changes, and therefore the installation location and installation direction of the exterior material affect the deterioration of the exterior material.

[0060] The storage device 40 stores the predicted result data 46 and the corrected result data 47 for each user 91. The predicted result data 46 and the corrected result data 47 are for each user ID, with the predicted result data 46 corresponding to each user ID and the corrected result data 47 corresponding to each user ID. The predicted result data 46 and the corrected result data 47 are calculated and recorded by the computer 21. Details of the predicted result data 46 and the corrected result data 47 will be described later.

[0061] The storage device 40 stores time-series data 48a of power measurement values ​​from the start of use for each user 91 (i.e., for each user ID). The time-series data 48a includes power measurement values ​​arranged in chronological order and measurement times associated with each power measurement value. Here, each time the computer 21 receives a power measurement value and a measurement time from the power management device 63 via the communication network 30, the computer 21 associates the power measurement value with the measurement time and records them in the storage device 40. In this way, the time-series data 48a is accumulated in the storage device 40. The time-series data 48a represents the change in power over time.

[0062] The storage device 40 stores, for each user 91, time-series data 48b of the amount of power consumed since the start of use. The time-series data 48b has power amounts arranged in chronological order and measurement times associated with each amount of power. Here, each time the computer 21 receives a measured power value and measurement time from the power management device 63 via the communication network 30, it calculates the amount of power consumed by adding the measured value to the cumulative total of the power measurements received up to that point. The computer 21 records the calculated amount of power consumed and the measurement time in the storage device 40, correlating them with each other. In this way, the time-series data 48b is accumulated in the storage device 40. The time-series data 48b represents the change in power consumption over time.

[0063] The storage device 40 stores time-series data 48c of the amount of solar radiation from the start of use for each user 91. The time-series data 48c includes solar radiation amounts arranged in chronological order and measurement times associated with each amount of solar radiation. Here, each time the computer 21 receives a power measurement value and measurement time from the power management device 63 via the communication network 30, it calculates the amount of solar radiation by dividing the measurement value by the area of ​​the solar panel 61 and multiplying it by the conversion efficiency of the solar panel 61, etc. In this way, the power generated by the solar panel 61 is converted into solar radiation. The computer 21 associates the calculated amount of solar radiation with the measurement time and records them in the storage device 40. In this way, the time-series data 48c is accumulated in the storage device 40. The time-series data 48c represents the change in the amount of solar radiation over time.

[0064] The storage device 40 stores, for each user 91, time-series data 48d of the accumulated amount of solar radiation since the start of use. The time-series data 48d includes accumulated amounts of solar radiation arranged in chronological order and measurement times associated with each amount of accumulated solar radiation. Here, each time the computer 21 calculates the amount of solar radiation as described above, it calculates the accumulated amount of solar radiation by adding the amount of solar radiation to the accumulated amount of solar radiation calculated up to that point. In this way, the amount of power generated by the solar panel 61 since the start of use is converted into the accumulated amount of solar radiation since the start of use. The computer 21 associates the calculated accumulated amount of solar radiation with the measurement time and records them in the storage device 40. In this way, the time-series data 48d is accumulated in the storage device 40. The time-series data 48d represents the change in the amount of accumulated solar radiation over time. If the solar panel 61 is not installed at the residence 92 of the user 91, the time-series data 48a, 48b, 48c, 48d associated with another user ID may be used in common with the time-series data 48a, 48b, 48c, 48d associated with the user ID of the user 91. In this case, it is preferable that the residence 92 not equipped with the solar panel 61 is located near the residence 92 of the user 91 who has the other user ID.

[0065] The storage device 40 stores distribution data 38 for each type of exterior material. Because distribution data 38 is prepared for each type of exterior material, each distribution data 38 is associated with a type ID. As shown in FIG. 6 , the distribution data 38 is data consisting of region-specific information and deterioration susceptibility for each region, more specifically, for each prefecture. Region-specific information is assigned to each region. Each region-specific information is a unique value, and the region is identified by its assigned region-specific information. Deterioration susceptibility represents the susceptibility of exterior materials to deterioration due to the influence of the region's weather environment, etc. Deterioration susceptibility is expressed in multiple stages, for example, four stages. The deterioration susceptibility assigned to a region is a value obtained statistically by investigating or inspecting the exterior materials of homes 92 located in that region. Such distribution data 38 represents the distribution of deterioration susceptibility by region. The distribution data 38 is updated by the administrator 94 when a new inspection or survey is performed.

[0066] Storage device 40 stores post list data 39 for each type of exterior material. Since post list data 39 is prepared for each type of exterior material, each piece of post list data 39 is associated with a type ID. Each time user 91 provides information using terminal device 10, the provided information is accumulated in post list data 39. Details of post list data 39 will be described later.

[0067] <Operation of the Deterioration Prediction Device and Terminal Device (1)> Below, a description will be given of a degradation prediction method using the terminal device 10, the degradation prediction device 20, and the storage device 40. In addition, a description will be given of the flow of processing executed by the computer 21 of the degradation prediction device 20 in accordance with the program 23. A description will be given of the flow of processing executed by the terminal device 10 in accordance with an application program. A description will be given of cooperation between the computer 21 of the degradation prediction device 20 and the terminal device 10.

[0068] (1) Login The user 91 operates the input device of the terminal device 10 to instruct the terminal device 10 to execute an application program. When the terminal device 10 receives the instruction, the terminal device 10 starts the application program. Then, the terminal device 10 accesses the deterioration prediction device 20 via the communication network 30 in accordance with the application program. Then, the computer 21 of the deterioration prediction device 20 sends information for displaying a login screen to the terminal device 10. When the terminal device 10 receives the information from the computer 21, the terminal device 10 displays the login screen on the display device in accordance with the information. The user 91 operates the input device of the terminal device 10 to input his / her own user ID and password into the terminal device 10 and instruct the terminal device 10 to log in. Then, the terminal device 10 acquires the user ID and password and transmits them to the deterioration prediction device 20. When the computer 21 of the deterioration prediction device 20 receives the user ID and password, the computer 21 compares the user ID and password with the comparison data 41. If the computer 21 determines through verification that the user ID and password are authentic, it permits login using that user ID. On the other hand, if the computer 21 determines through verification that the user ID and password are false, it does not permit login and retransmits information to display the login screen to the terminal device 10. This allows the user 91 to attempt to log in again.

[0069] (2) Displaying the menu screen When login with the user ID of user 91 is permitted, computer 21 transmits information for displaying a menu screen to terminal device 10. When terminal device 10 receives the information from computer 21, terminal device 10 displays the menu screen on the display device in accordance with the information.

[0070] On the menu screen, the user 91 can issue a command to start the electronic bulletin board. That is, a button or tab for starting the electronic bulletin board as an element of a GUI (Graphical User Interface) is arranged on the menu screen, and the user 91 can issue a command to start the electronic bulletin board to the terminal device 10 by operating the input device of the terminal device 10. The electronic bulletin board is also called an electronic conference room.

[0071] On the menu screen, the user 91 can issue a command to start deterioration prediction. That is, a button or tab for starting deterioration prediction as an element of a GUI (Graphical User Interface) is arranged on the menu screen, and the user 91 can issue a command to start deterioration prediction to the terminal device 10 by operating the input device of the terminal device 10.

[0072] (3) Prediction of deterioration When the user 91 selects and confirms the deterioration prediction start button or tab by operating the input device of the terminal device 10, the terminal device 10 recognizes the command to start deterioration prediction and commands the computer 21 to start deterioration prediction.

[0073] When the computer 21 receives a command to start deterioration prediction, the computer 21 reads the exterior material list data 45 associated with the user ID that has been authorized to log in. Furthermore, the computer 21 reads from the characteristic list data 44 the type coefficient associated with the same type ID as the type ID in the exterior material list data 45.

[0074] Next, the computer 21 predicts the progression of the deterioration level of each exterior material for each component number in the exterior material list data 45 (i.e., for each exterior material identified by the component number), based on the type, material, installation position, and installation direction of the exterior material. That is, the computer 21 calculates an aging function for each exterior material identified by the component number, based on the type coefficient and installation coefficient. Specifically, the computer 21 calculates the aging function for each exterior material identified by the component number by calculating a coefficient in the aging function (hereinafter referred to as the aging coefficient) from the type coefficient and installation coefficient. The aging function represents the progression of the deterioration level of the exterior material over time. The aging function will be described in detail below.

[0075] Figure 5 is a graph showing an aging deterioration function. In Figure 5, the horizontal axis represents the time since the exterior material began to be used, and the vertical axis represents the degree of deterioration of the exterior material. The time when the exterior material began to be used is, for example, the time when user 91's house 92 was completed. As is clear from Figure 5, the aging deterioration function uses the time since the beginning of use and the degree of deterioration of the exterior material as variables to represent the relationship between time and the degree of deterioration using an aging deterioration coefficient. Therefore, the aging deterioration function shows the progression of the degree of deterioration of the exterior material over time. In the aging deterioration function, the degree of deterioration increases as time passes. In the graph, the aging deterioration function is represented by a line, and this line is called the aging deterioration line. In the aging deterioration function, the variable representing time is called the time variable, and the variable representing the degree of deterioration is called the deterioration degree variable.

[0076] For example, the aging function is a linear function in which the order of the time variable and the order of the deterioration degree variable are 1. The slope as a coefficient of the linear function is the aging coefficient calculated by the computer 21 from the type coefficient and the installation coefficient. The intercept "0" as a coefficient of the linear function is the aging coefficient calculated by the computer 21 from the type coefficient and the installation coefficient. The minimum unit of time in the aging function is not limited, and may be, for example, 1 second, 1 minute, 1 hour, 6 hours, 12 hours, 24 hours, 1 week, 2 weeks, 1 month, 3 months, 6 months, or 1 year. Time may be expressed in calendar terms.

[0077] The aging coefficient in the aging function may be calculated by taking into account the environmental coefficient in addition to the type coefficient and installation coefficient. That is, the computer 21 may calculate the aging function by calculating the aging coefficient in the aging function for each exterior material identified by the component number from the type coefficient, installation coefficient, and environmental coefficient. The environmental coefficient is a coefficient calculated based on the environmental influences that the house 92 has experienced since its inception. The environmental influences refer to factors that cause deterioration of the house 92, such as weather, disasters, air conditioning, heating, humidity, and surrounding vegetation. The environmental coefficient may be calculated from meteorological information, such as temperature history, wind speed history, wind direction history, and airborne salinity concentration, from its inception to the present. The environmental coefficient may also be calculated from disaster information (e.g., the date of occurrence, seismic intensity, information on flooding under the floor, instantaneous wind speed, or instantaneous precipitation) related to natural disasters, such as earthquakes, tsunamis, typhoons, and heavy rains, that have occurred since its inception to the present. The environmental coefficient may also be calculated from disaster information and meteorological information. The environmental coefficient may be a coefficient calculated from indoor environment information such as indoor temperature history and indoor humidity history from the start of use to the present. The environmental coefficient may be a frost damage coefficient or a north wind coefficient. The environmental coefficient may be a coefficient calculated from the history of the difference between indoor and outdoor temperatures. The environmental coefficient is stored in the storage device 40 or the storage device 22. The environmental coefficient may be calculated, for example, by the computer 21 periodically downloading weather information or disaster information stored in a weather information database connected to the communication network 30. The environmental coefficient may be calculated by the administrator 94 and recorded in the storage device 40 or the storage device 22.

[0078] The aging coefficient in the aging function may be calculated by taking into account the repair history coefficient in addition to the type coefficient and installation coefficient. That is, the computer 21 may calculate the aging function by calculating the aging coefficient in the aging function for each exterior material identified by the component number from the type coefficient, installation coefficient, and repair history coefficient. The repair history coefficient is a coefficient calculated based on the repairs that the exterior materials of the house 92 have received since the house was first used. Repairs refer to factors that increase the degree of deterioration of the exterior materials or slow the progression of deterioration, such as repairs and replacements of the exterior materials. The repair history coefficient may be calculated by the administrator 94 and recorded in the storage device 40 or the storage device 22, for example. The repair history coefficient may be calculated by the administrator 94 or the computer 21 based on information entered by the user 91 into the terminal device 10 and transmitted to the computer 21, and then recorded in the storage device 40 or the storage device 22. The repair history coefficient may be updated each time calculation is performed by the administrator 94 or the computer 21. By updating the repair history coefficient, the aging deterioration function is corrected and updated when a prediction is made again.

[0079] (4) Prediction of current deterioration Next, the computer 21 recognizes the current time. Then, for each exterior material identified by the component number, the computer 21 predicts the current deterioration level of the exterior material based on the current time and the aging deterioration function. Specifically, the computer 21 calculates the deterioration level by applying the current time to the time variable of the aging deterioration function, and sets this deterioration level as the current deterioration level of the exterior material. Note that the current deterioration level calculated when the aging deterioration coefficient in the aging deterioration function is calculated taking into account the repair history coefficient is lower than the current deterioration level calculated otherwise.

[0080] (5) Maintenance timing prediction Next, computer 21 reads from characteristic list data 44 the allowable deterioration level associated with the same type ID as the type ID in exterior material list data 45. Then, for each exterior material identified by the component number, computer 21 predicts the maintenance timing of the exterior material based on the allowable deterioration level and the aging deterioration function. Specifically, computer 21 calculates the time by applying the allowable deterioration level to the deterioration level variable of the aging deterioration function, and sets that time as the maintenance timing.

[0081] (6) Recording of prediction results Next, computer 21 records prediction result data 46 in storage device 40. That is, for each exterior material identified by the component number, computer 21 associates the predicted deterioration degree transition of the exterior material (specifically, the deterioration coefficient in the deterioration function), the current deterioration degree, and the maintenance timing with the component number, and further associates these with a user ID, and records the component number, deterioration degree transition, current deterioration degree, and maintenance timing in storage device 40. As shown in Fig. 7, prediction result data 46 consists of one or more items, and each item consists of a component number, an aging deterioration coefficient in the deterioration function, the current deterioration degree, and the maintenance timing.

[0082] (7) Display of prediction results Next, the computer 21 generates prediction result display information for each exterior material identified by the component number, according to the prediction result data 46. The prediction result display information is information for displaying the predicted deterioration progression of the exterior material (the deterioration coefficient in the deterioration function), the current deterioration degree, and the maintenance timing. Next, the computer 21 transmits the prediction result display information to the terminal device 10. When the terminal device 10 receives the prediction result display information from the computer 21, the terminal device 10 displays the predicted deterioration progression of the exterior material, the current deterioration degree, and the maintenance timing on the display device according to the prediction result display information. Figure 8 shows an example of a display screen 100. The screen 100 is arranged with a graph 101, a presentation unit 102, a presentation unit 103, a correction start button 104, and a home button 105.

[0083] Graph 101 shows the predicted progression of the deterioration degree of the exterior material. In graph 101, the horizontal axis represents time, the vertical axis represents the deterioration degree, and an aging deterioration function that represents the relationship between time and the deterioration degree using an aging deterioration coefficient is drawn as a line, which is the aging deterioration line. The presentation unit 102 displays the value of the current degradation level in text and also indicates the value of the current degradation level on the graph 101 with an arrow. The presentation unit 103 displays the maintenance timing value in text and indicates the maintenance timing value with an arrow on the graph 101. The presentation unit 103 may also present text, images, or videos that show a maintenance method for the exterior material. The correction start button 104 is a GUI element for instructing the computer 21 to start the process of correcting the predicted deterioration degree transition, the current deterioration degree, and the maintenance timing. The home button 105 is a GUI element for instructing the computer 21 to transition from the screen 100 to a menu screen. When the user 91 operates the terminal device 10 to select and confirm the home button 105, the terminal device 10 recognizes the selection of the home button 105 and then transmits a screen transition command to the computer 21 of the deterioration prediction device 20. The computer 21 that receives the command transmits information for displaying the menu screen to the terminal device 10, and the menu screen is displayed on the display device of the terminal device 10. In addition to the graph 101, presentation unit 102, presentation unit 103, correction start button 104, and home button 105, a cost presentation unit may be arranged on the screen 100. The cost presentation unit displays a first maintenance cost and a second maintenance cost. The first maintenance cost is the cost if the exterior material is currently maintained. The second maintenance cost is the cost if the exterior material is not currently maintained but is maintained at the maintenance time. The first maintenance cost and the second maintenance cost are calculated from the current deterioration level by the computer 21, for example, and transferred from the computer 21 to the terminal device 10, and displayed by the terminal device 10. In addition to the graph 101, the presentation unit 102, the presentation unit 103, and the correction start button 104, a house model or an exterior material model may be arranged on the screen 100. The house model or the exterior material model is a two-dimensional or three-dimensional CG (Computer Graphics) model of a house or an exterior material. The house model or the exterior material model may be a two-dimensional or three-dimensional model in which the house or the exterior material is personified by a character. The house model or the exterior material model may be a two-dimensional or three-dimensional model in which the house or the exterior material is personified by a status character. The status character refers to a state character whose appearance is expressed based on the current deterioration level. For example, as the current deterioration level increases, the vitality of the status character decreases, and the terminal device 10 generates a state character with such an appearance as a house model or an exterior material model and displays it on the display device.

[0084] When the user 91 commands the display of the predicted results for other exterior materials by operating the input device of the terminal device 10, the display on the terminal device 10 switches to display the progress of the deterioration level of the other exterior materials, the current deterioration level, and the maintenance timing.

[0085] The computer 21 may transmit an alarm command signal to the terminal device 10 periodically or when a disaster occurs. When the terminal device 10 receives the alarm command signal, the terminal device 10 outputs an alarm by voice or video. The output of the alarm prompts the user 91 to select and confirm the correction start button 104 on the display screen 100.

[0086] Incidentally, the exterior material has been exposed to the outdoors since the start of use until the present. Therefore, the deterioration of the exterior material is affected by solar radiation from the start of use until the present. However, because the deterioration level transition (specifically, graph 101), current deterioration level (specifically, display unit 102), and maintenance timing (specifically, display unit 103) displayed on the terminal device 10 are standard, the deterioration level transition, current deterioration level, and maintenance timing displayed on the terminal device 10 hardly reflect the influence of solar radiation from the start of use until the present. Therefore, correction is performed by the terminal device 10 and the computer 21 so that the solar radiation from the start of use until the present is reflected. The correction will be described in detail below.

[0087] (8) Correction (8-1) Command to start correction When the user 91 selects and confirms the correction start button 104 on the display screen 100 of the prediction result by operating the input device of the terminal device 10, the terminal device 10 recognizes this. Then, the terminal device 10 transmits a command to start correction to the computer 21. As a result, the computer 21 recognizes the command to start correction.

[0088] (8-2) Points added When the computer 21 receives a command to start correction from the terminal device 10, the computer 21 identifies the point data 42 associated with the user ID that is permitted to log in, using that user ID. Next, the computer 21 adds a predetermined number of additional points to the points of the identified point data 42. Then, the computer 21 updates the points of the point data 42 to the points after the addition.

[0089] (8-3) Correction processing The computer 21 corrects the deterioration level transition, the current deterioration level, and the maintenance timing based on the power time-series data 48a, the power energy time-series data 48b, the solar radiation time-series data 48c, or the integrated solar radiation time-series data 48d. The correction process is specifically as follows (8-3-1) to (8-3-4). The corrected deterioration level transition is referred to as the corrected transition, the corrected current deterioration level is referred to as the corrected deterioration level, and the corrected maintenance timing is referred to as the corrected maintenance timing.

[0090] (8-3-1) Calculation of correction coefficient The computer 21 calculates a correction coefficient based on the time-series data 48d of the amount of integrated solar radiation. For example, the computer 21 may calculate an average increase in the amount of integrated solar radiation per unit time from the time-series data 48d that represents the change in the amount of integrated solar radiation over time, and use this as the correction coefficient. For example, the computer 21 may calculate an average increase in the amount of integrated solar radiation per unit time from the time-series data 48d that represents the change in the amount of integrated solar radiation over time, and use the product of this increase by a predetermined coefficient as the correction coefficient. The computer 21 may calculate the correction coefficient based on the time series data 48a of the power, the time series data 48b of the amount of power, or the time series data 48c of the amount of solar radiation.

[0091] (8-3-2) Corrected Trend Forecast Next, the computer 21 predicts the corrected progression of the deterioration degree of the exterior material based on the type, material, installation position, installation direction, and correction coefficient of the exterior material. That is, the computer 21 calculates a corrected aging function based on the type coefficient, installation coefficient, and correction coefficient. Specifically, the computer 21 calculates the corrected aging function by calculating the coefficient in the corrected aging function (hereinafter referred to as the corrected aging coefficient) from the type coefficient, installation coefficient, and correction coefficient. The corrected aging function corresponds to the corrected progression of the deterioration degree of the exterior material.

[0092] FIG. 9 is a graph showing the corrected aging function with a solid line and the uncorrected aging function with a dashed line. In FIG. 9, the horizontal axis represents the time since the start of use of the exterior material, and the vertical axis represents the degree of deterioration of the exterior material. As is clear from FIG. 9, the corrected aging function uses the time since the start of use and the degree of deterioration of the exterior material as variables, and expresses the relationship between time and the degree of deterioration using a corrected aging coefficient. Therefore, the corrected aging function shows the progression of the degree of deterioration over time. In the corrected aging function, the degree of deterioration increases as time passes.

[0093] For example, the corrected aging deterioration function is a linear function in which the order of the time variable and the order of the deterioration degree variable are 1. The slope as a coefficient of the linear function is the corrected aging deterioration coefficient calculated by the computer 21 from the type coefficient, installation coefficient, and correction coefficient. The intercept "0" as a coefficient of the linear function is the corrected aging deterioration coefficient calculated by the computer 21 from the type coefficient, installation coefficient, and correction coefficient.

[0094] If the average increase in the amount of integrated solar radiation per unit time in the time-series data 48d is greater than the standard, it means that more solar radiation is incident on the exterior material, and the exterior material is more deteriorated than the standard. Therefore, the slope of the corrected aging function, such as the solid line 201 in Figure 9, is greater than the slope of the uncorrected aging function, such as the dashed line 203 in Figure 9. On the other hand, if the average increase in the amount of integrated solar radiation per unit time in the time-series data 48d is smaller than the standard, then less solar radiation is incident on the exterior material, and the exterior material is less deteriorated than the standard. The slope of the corrected aging function, such as the solid line 202 in Figure 9, is smaller than the slope of the uncorrected aging function, such as the dashed line 203 in Figure 9.

[0095] The corrected aging coefficient in the corrected aging function may be calculated by taking into account the repair history coefficient in addition to the type coefficient, installation coefficient, and correction coefficient. In other words, the computer 21 may calculate the corrected aging function by calculating the corrected aging coefficient in the corrected aging function from the type coefficient, installation coefficient, correction coefficient, and repair history coefficient. The repair history coefficient is a coefficient calculated based on the repairs that have been made to the exterior materials of the house 92 since the house was first used. Repairs refer to factors that increase the degree of deterioration of the exterior materials or slow the progression of deterioration, such as repairs and replacements of the exterior materials. The repair history coefficient may be calculated by the administrator 94 and recorded in the storage device 40 or the storage device 22, for example. The repair history coefficient may be calculated by the administrator 94 or the computer 21 based on information entered by the user 91 into the terminal device 10 and transmitted to the computer 21, and then recorded in the storage device 40 or the storage device 22. The repair history coefficient may be updated for each calculation by the administrator 94 or the computer 21. By updating the repair history coefficient, the corrected aging deterioration function is corrected and updated when a prediction is made again.

[0096] (8-3-3) Corrected Deterioration Prediction Next, the computer 21 recognizes the current time. Then, the computer 21 predicts the corrected deterioration degree of the exterior material based on the current time and the corrected aging deterioration function. Specifically, the computer 21 calculates the deterioration degree by applying the current time to the time variable of the corrected aging deterioration function, and sets this deterioration degree as the corrected deterioration degree of the exterior material. Note that the current deterioration degree calculated when the corrected aging deterioration coefficient in the corrected aging deterioration function is calculated taking into account the repair history coefficient is lower than the current deterioration degree calculated otherwise.

[0097] (8-3-4) Corrected maintenance timing forecast Next, the computer 21 predicts the corrected maintenance timing of the exterior material based on the allowable deterioration level and the corrected aging deterioration function. Specifically, the computer 21 calculates the time by applying the allowable deterioration level to the deterioration level variable of the corrected aging deterioration function, and sets this time as the corrected maintenance timing.

[0098] (8-4) Recording of correction results After the correction process, the computer 21 records the correction result data 47 in the storage device 40. That is, for each exterior material identified by the component number, the computer 21 associates the corrected transition (specifically, the corrected aging deterioration coefficient in the corrected aging deterioration function), the corrected deterioration level, and the corrected maintenance timing with the component number, and further associates these with a user ID, and records the component number, the corrected transition, the corrected deterioration level, and the corrected maintenance timing in the storage device 40. As shown in Fig. 10, the correction result data 47 consists of one or more items, and each item consists of the component number, the corrected aging deterioration coefficient in the corrected aging deterioration function, the corrected deterioration level, and the corrected maintenance timing.

[0099] (8-5) Display of correction results Next, the computer 21 generates correction result display information for each exterior material identified by the component number in accordance with the correction result data 47. The correction result display information is information for displaying the corrected transition (the corrected aging deterioration coefficient in the corrected aging deterioration function), the corrected deterioration level, and the corrected maintenance timing. Next, the computer 21 transmits the correction result display information to the terminal device 10. When the terminal device 10 receives the correction result display information from the computer 21, the terminal device 10 displays the corrected transition, the corrected deterioration level, and the corrected maintenance timing on the display device in accordance with the correction result display information. FIG. 11 shows an example of a screen 120 for the display. The screen 120 is arranged with a graph 121, a presentation unit 122, a presentation unit 123, a correction start button 124, and a home button 125.

[0100] Graph 121 shows the corrected transition. In graph 121, the horizontal axis represents time, the vertical axis represents the degree of deterioration, and a corrected aging function that represents the relationship between time and the degree of deterioration using a corrected aging coefficient is drawn as a line. The presentation unit 122 displays the value of the corrected degradation degree in text and also indicates the value of the corrected degradation degree on the graph 121 with an arrow. The presentation unit 123 displays the corrected maintenance time value in text and also indicates the corrected maintenance time value on the graph 121 with an arrow. The correction start button 124 is a GUI element for instructing the computer 21 to start the process of correcting the corrected transition, the corrected deterioration level, and the corrected maintenance timing. When the user 91 selects and confirms the correction start button 124, the processes described in "(8-1) Command to start correction" to "(8-5) Display of correction results" are executed again by the terminal device 10 and the computer 21. The home button 125 is a GUI element for instructing the computer 21 to transition from the screen 120 to a menu screen. When the user 91 operates the terminal device 10 to select and confirm the home button 125, the terminal device 10 recognizes the selection of the home button 125 and then transmits a screen transition command to the computer 21 of the deterioration prediction device 20. The computer 21 that receives the command transmits information for displaying the menu screen to the terminal device 10, and the menu screen is displayed on the display device of the terminal device 10. In addition to the graph 121, the presentation unit 122, the presentation unit 123, and the correction start button 124, a cost presentation unit may be arranged on the screen 120. The cost presentation unit displays a first corrected cost and a second corrected cost. The first corrected cost is the cost if the exterior material is currently maintained. The second corrected cost is the cost if the exterior material is not currently maintained but is maintained at the maintenance time. The first corrected cost and the second corrected cost are calculated from the corrected deterioration level by the computer 21, transferred from the computer 21 to the terminal device 10, and displayed by the terminal device 10. In addition to the graph 121, the presentation unit 122, the presentation unit 123, and the correction start button 124, a house model or an exterior material model may be arranged on the screen 120. The house model or the exterior material model is a two-dimensional or three-dimensional model of a house or an exterior material. The house model or the exterior material model may be a two-dimensional or three-dimensional model in which the house or the exterior material is personified by a character. The house model or the exterior material model may be a two-dimensional or three-dimensional model in which the house or the exterior material is personified by a status character. The status character refers to a state character whose appearance is expressed based on the corrected deterioration level. For example, as the corrected deterioration level increases, the vitality of the status character decreases, and the terminal device 10 generates a state character with such an appearance as a house model or an exterior material model and displays it on the display device.

[0101] <Beneficial Effect (1)> Solar panels 61 are installed on a house 92, generate power from the energy of sunlight incident on them, and the power generated by the solar panels 61 is measured by a power meter 62. Power time-series data 48a is a chronological arrangement of power measurement values ​​measured by the power meter 62 and the corresponding measurement times. Power amount time-series data 48b is a chronological arrangement of power amounts calculated from the power measurement values ​​measured by the power meter 62 and the corresponding measurement times. Solar radiation time-series data 48c is a chronological arrangement of solar radiation amounts converted from the power measurement values ​​measured by the power meter 62 and the corresponding measurement times. Integrated solar radiation time-series data 48d is a chronological arrangement of integrated solar radiation amounts converted from the power measured by the power meter 62 and the corresponding measurement times. A correction coefficient is calculated based on power time series data 48a, power energy time series data 48b, solar radiation time series data 48c, or integrated solar radiation time series data 48d, and a corrected aging deterioration coefficient in the corrected aging deterioration function is calculated based on the correction coefficient. Because the corrected aging deterioration function is calculated as described above, the progression of the degree of deterioration of the exterior material represented by the corrected aging deterioration function reflects the influence of solar radiation on the solar panels 61 of the house 92. The corrected deterioration degree and corrected maintenance timing calculated from the corrected aging deterioration function and the current time also reflect the influence of solar radiation on the solar panels 61 of the house 92.

[0102] When the user selects and confirms the button 104, 124, points are added to the point data 42. These points have economic value. Therefore, adding points motivates the user to select and confirm the button 104, 124. This increases the frequency of correction of the aging deterioration function, and also increases the opportunities for the user to know the accurate corrected deterioration function, corrected deterioration degree, and corrected maintenance timing.

[0103] As described above, the screens 100 and 120 display the deterioration progression, current deterioration level, and maintenance schedule of the exterior materials of the house 92. This allows the user 91 to maintain or replace the exterior materials at the appropriate time. This prevents excessive maintenance or replacement of the exterior materials. Meanwhile, in recent years, there has been a demand for a decarbonized society through the promotion of carbon neutrality, which essentially reduces carbon dioxide emissions, and for the Sustainable Development Goals (SDGs). In response, the construction industry is also working to convert buildings to wooden structures with low carbon dioxide emissions. Because the screens 100 and 120 contribute to reducing the frequency of exterior material maintenance and replacement, this deterioration prediction system 1 can contribute to the realization of a decarbonized society and the achievement of the Sustainable Development Goals.

[0104] <Operation of the deterioration prediction device and terminal device (2)> As described above, screens 100 and 120 display the progression of deterioration of the exterior materials of home 92, the current degree of deterioration, and the maintenance schedule. Therefore, screens 100 and 120 arouse user 91's interest in the exterior materials of home 92 and their deterioration. Therefore, screens 100 and 120 motivate user 91 to inspect and maintain the exterior materials of home 92. When user 91 requests a contractor to inspect and maintain the exterior materials of his or her home 92 and the inspection and maintenance of the exterior materials of his or her home 92 is performed, user 91 can learn the deterioration status of the exterior materials of his or her home 92. Information regarding the deterioration of the exterior materials of user 91's home 92 is also useful to other users 91 who own other homes 92 using the same type of exterior materials. Therefore, deterioration prediction system 1 allows information to be shared among multiple users 91 who use the same type of exterior materials. To share information, user 91 must provide the information. Below, we will explain the flow of processing that the computer 21 of the deterioration prediction device 20 executes in accordance with the program 23 when the user 91 provides information. We will also explain the flow of processing that the terminal device 10 executes in accordance with an application program. We will explain the cooperation between the computer 21 of the deterioration prediction device 20 and the terminal device 10, and we will also explain an information provision method using the terminal device 10, imaging device 11, deterioration prediction device 20, and storage device 40.

Note that the user 91 here may be the same person as the user 91 in "Operation of Deterioration Prediction Device and Terminal Device (1)" or a different person. In other words, the user ID permitted to log in here may be the same as or different from the user ID permitted to log in in "Operation of Deterioration Prediction Device and Terminal Device (1)."

[0106] (2A) Display of the second menu screen When the user 91 selects and confirms the button or tab to start the electronic bulletin board by operating the input device of the terminal device 10, the terminal device 10 recognizes the command to start the electronic bulletin board. Then, the terminal device 10 accesses the computer 21 of the deterioration prediction device 20 and commands the computer 21 to start the electronic bulletin board. When the computer 21 receives the command to start the electronic bulletin board, the computer 21 sends information for displaying a second menu screen to the terminal device 10. When the terminal device 10 receives the information from the computer 21, the terminal device 10 displays the second menu screen on the display device in accordance with that information. Details of the second menu screen have been described above.

[0107] On the second menu screen, the user 91 can select between information provision and information viewing. In other words, an information provision button or tab as a GUI element is arranged on the second menu screen, and when the user 91 selects and confirms the information provision button or tab by operating the input device of the terminal device 10, the user can instruct the terminal device 10 to start processing related to information provision. On the other hand, an information viewing button or tab as a GUI element is arranged on the second menu screen, and when the user 91 selects and confirms the information viewing button or tab by operating the input device of the terminal device 10, the user can instruct the terminal device 10 to start processing related to information viewing.

[0108] (3A) Display of the list of exterior materials The user 91 commands the terminal device 10 to start processing related to information provision on the second menu screen. The terminal device 10 then recognizes the command and commands the computer 21 to start processing related to information provision. When the computer 21 receives the command, it reads the exterior material list data 45 associated with the user ID who has been granted permission to log in. Based on the exterior material list data 45, the computer 21 generates list information related to a list of exterior materials to be used for the user 91's house 92. The list information consists of one or more items, each of which is composed of a component number and a type ID. The computer 21 then transmits the list information to the terminal device 10. When the terminal device 10 receives the list information from the computer 21, the terminal device 10 displays, on the display device, a list consisting of multiple items (the items correspond to the exterior materials to be used for the user 91's house 92) associated with the component number and type ID. In addition to the list, the terminal device 10 may also display, on the display device, a CG house model and an indicator indicating on the house model where the exterior material corresponding to the item will be installed on the house 92.

[0109] (4A) Identifying Type ID The user 91 operates the input device of the terminal device 10 to select and confirm one item from the list on the list display screen. The terminal device 10 then identifies the component number and type ID associated with the selected and confirmed item. This selects one exterior material from the multiple exterior materials used for the house 92 of the user 91.

[0110] (5A) Display of input screen and reception of input information Next, the terminal device 10 displays on the display device an input screen for the user 91 to input information regarding the deterioration of the exterior materials. FIG. 12 shows an example of such an input screen 150. The input screen 150 has presentation units 151a to 151g, answer input units 152a to 152g, and a decision button 153.

Then, the terminal device 10 recognizes the information input into the answer input sections 152a to 152e and 152g and displays the information in the answer input sections 152a to 152e and 152g. The user 91 also operates the input device of the terminal device 10 to select the actual image 13. The terminal device 10 then displays the file name of the selected actual image 13 in the answer input section 152e. The actual image 13 shows the exterior materials of the house 92. As described above, the actual image 13 may be captured in advance or in real time at this point in time. In the latter case, when the user 91 operates the input device of the terminal device 10 to start the imaging device 11 and capture an image of the exterior materials with the imaging device 11, the imaging device 11 captures the exterior materials and transfers the actual image 13 showing the exterior materials to the terminal device 10, which then stores the actual image 13. Some examples of the actual image 13 have been described above.

[0113] Thereafter, the user 91 selects and confirms the decision button 153 by operating the input device of the terminal device 10. Then, the terminal device 10 confirms the information input in the answer input sections 152a to 152e, 152g, and also confirms the selection in the answer input section 152e as the actual image 13. This causes the terminal device 10 to accept information related to the deterioration of the exterior material. The information related to the deterioration of the exterior material includes the information input in the answer input sections 152a to 152e, 152g, and the actual image 13 selected in the answer input section 152e.
