  Embodiments of the present invention will be described below with reference to the drawings.

<Embodiment>
FIG. 1 shows an exterior maintenance system 100 and color difference measuring means 200 according to this embodiment. As the color difference measuring means 200, an existing simple spectral color difference meter capable of measuring the color difference can be used.

  The exterior maintenance system 100 includes a control unit 10, a storage unit 20, an input unit 30, a printing unit 40, and a display unit 50.

  The control unit 10 operates based on an operating system (OS) stored in the storage medium 20 or the like, and calculates various data such as data input from the input unit 30 and data stored in the storage unit 20 according to an application program. It performs processing, and inputs and outputs control signals and the like for performing various processing such as display processing, printing processing, and updating of data in the storage means.

  The storage means 20 stores various data such as a program such as an OS, a basic maintenance program shown in FIG. 2 displayed on the display means 40, a maintenance program for each property shown in FIG. 4, and a selected material database shown in FIG.

  The input means 30 inputs various data such as area name, property name (Mr. A, etc.), color difference (ΔE) obtained by the color difference measuring means, gloss retention, chalking, mold and algae deterioration data, etc. And an operation signal corresponding to a user operation is output to the control means 10.

  The display means 40 is composed of a liquid crystal screen, for example. The display means 40 displays an image corresponding to the display signal from the control means 10 on the screen. Specifically, the display unit 40 displays the data stored in the storage unit 20 on the screen as a table according to a control signal from the control unit 10.

  The printing unit 50 is, for example, a printer, and operates based on a print control signal from the control unit 10 to execute a printing process.

  As shown in FIG. 2, in the exterior material maintenance system 100, the storage means 20 stores the regional name, site (outer wall, roof, sealing material, etc.), orientation, and solar radiation for each orientation surface in each region. A basic maintenance program A0000 consisting of quantity, paint specifications, color and manufacturer is stored. Here, the memory | storage means 20 is matched with the area name of each said area (for example, "A prefecture a city" etc. of a building area column), and the coating material corresponding to the solar radiation amount (1,0.6) for every azimuth | direction surface. The paint specific data (“lifetime”, “paint specifications (acrylic silicone type, urethane type)”, “manufacturer”, etc.) for specifying the specifications of the product is stored.

  When the area name input by the input means 30 is input, the control means 10 reads paint specifying data corresponding to the amount of solar radiation for each azimuth plane from the storage means 20 according to the input area name. The display means 40 displays the paint specifications corresponding to the amount of solar radiation for each azimuth plane. For example, if “A prefecture a city” is entered in the input field of the area name of the building site displayed on the display means, the control means 10 will change from the basic maintenance program “A0000” to “A prefecture a city” along with the title line. A row portion (A portion) corresponding to the data is extracted and displayed on the display means 40.

The amount of solar radiation (coefficient) shown in the basic maintenance program “A0000” is, for example, a graph as shown in FIG. 3, obtaining the annual amount of solar radiation (MJ / m ² years) for each direction of the building, It is determined as the relative amount of solar radiation for each azimuth when “1.0” is set. Here, annual cumulative amount of solar radiation (MJ / m ² years) can be calculated by using a calculation software that New Energy and Industrial Technology Development Organization (NEDO) to provide (METPV3). In the example shown in FIG. 3, the solar radiation amount (coefficient) is set as the solar radiation amount to the outer wall as the south surface “1.0”, the east / west surface “0.6”, and the north surface “0.3”. In this embodiment, with a basic maintenance cycle of 10 years, there is a relationship between the amount of solar radiation (coefficient) and the specifications of the paint actually used (“lifetime”, “paint specifications”, “manufacturer”, etc. in FIG. 2). It is determined. That is, when the amount of solar radiation (coefficient) is “1.0”, a paint having a service life of 10 years is selected, and “Company A, acrylic silicon type” is set as an initial value. Moreover, when the solar radiation amount (coefficient) on the east and west sides is “0.6”, there is no paint with a service life of 6 years in the selected material database, so a paint with a service life of 8 years is selected. “Company A, urethane system” is set as the initial value. In addition, when the amount of solar radiation (coefficient) is “0.3”, there is no paint with a service life of 3 years in the selected material database, so a paint with a service life of 5 years is selected. "Is set as an initial value. Note that these initial value setting methods can be arbitrarily set by the user.

  According to the present embodiment, the paint specific data corresponding to the amount of solar radiation for each azimuth plane is read from the storage means 20 according to the input arbitrary area name, thereby corresponding to the amount of solar radiation for each azimuth plane. Since the specification of the paint can be displayed on the display means, it is possible to obtain the specification of the paint for each azimuth plane according to the amount of solar radiation that differs for each region.

  Next, with reference to FIG. 2 to FIG. 8, the change of the basic maintenance program will be described.

  The storage means 20 stores in advance the degree of deterioration of the paint after a predetermined period (FIG. 6) in association with paint specific data (“paint specification”, “maker”, etc. in FIG. 2). In FIG. 6, the degree of deterioration relating to “color difference (ΔE)”, “gloss retention”, “chalking”, and “mold / algae” is shown. The degree of deterioration shown in FIG. 6 can be obtained from accelerated test data. As an example, FIG. 7 shows data obtained by an accelerated test for color difference (ΔE). The accelerated test can be performed using, for example, a metal halide lamp having a UV irradiation amount about 100 times that of sunlight. Further, the degree of deterioration from the initial setting (at the time of new construction) can be measured using an existing glossy watch for “Gloss retention” and a chalking measuring tape for “Chalk”.

  Then, after a predetermined period shown in FIG. 5 (“10 years” in the present embodiment), when the property name and the deterioration degree of the paint are input for each of the azimuth planes by the input unit 30, the control unit 10 The deterioration degree (FIG. 6) stored in the storage means 20 and the input deterioration degree (FIG. 5) are compared for each azimuth plane. Specifically, the deterioration index of the property “Mr. A” shown in FIG. 5 is about “2/3 of the south surface” for the east and west surfaces, and “1/2 of the south surface” for the north surface. Here, the ratio of the deterioration degree of each azimuth plane when the deterioration degree of the south face is “1” is referred to as a deterioration index. The measured south surface degradation degree “6” in FIG. 5 matches the degradation degree “6” in the selected material database in FIG. For this reason, “Company A, acrylic silicon system”, which is the same as the basic maintenance program of “A case b city”, will be adopted for the south side. On the east and west sides, “Company A, acrylic silicon system” was used in the basic maintenance program of “A Case b City”, but the deterioration index was about “2/3” and the deterioration level was lower than the initial setting. Adopt a paint (Company B, Urethane, 8 years) that is small and has a useful life of about 6.7 years or more. Similarly, for the north surface, since the deterioration index is “1/2”, a paint having a service life of about 5 years or more (Company C, acrylic type, 5 years) is adopted.

  As described above, the maintenance program for the property “Mr. A” is changed from the basic maintenance program (B city in A prefecture) of FIG. 4A to FIGS. 8A and 8B as shown in FIG. Maintenance programs A0001 and A0002 shown in FIG. Here, A0001 indicates a maintenance program for the 10th and 20th years (a maintenance program every 10 years), and A0002 indicates a maintenance program for the 25th year (a maintenance program every 15 years).

  FIG. 5 shows gloss retention and chalking as other degrees of deterioration. Here, assuming that the gloss retention rate (deterioration degree) of the south surface is “1”, the deterioration index of the gloss retention rate of the east and west surfaces is “twice the south surface”, and the north surface is “three times the south surface”. It is. The measured south surface degradation degree “20” in FIG. 5 matches the degradation degree “20” in the selected material database in FIG. If the gloss retention rate is the standard for changing the basic maintenance program, the deterioration index of gloss retention rate on the east and west surfaces is “twice that of the south surface”, so that paint with a service life of 5 years (for example, C Acrylic). However, in the present embodiment, when various deterioration indexes (deterioration degrees) are compared, the specification of the paint having a long service life is selected. That is, the deterioration degree is composed of a plurality of items (“color difference (ΔE)”, “gloss retention”, “chalk”), and the deterioration degree of the reference azimuth plane (south face) (color difference “6” in FIG. 5, gloss Deterioration index of a plurality of different items for each azimuth plane obtained with a retention rate of 20%) as a reference value “1.0” (for example, the color difference between the east and west sides in FIG. The deterioration index of the gloss retention rate on the west surface is evaluated as “twice that of the south surface”), and the specification of the paint for each azimuth surface is determined and displayed on the display means 40. Even in the chalking, the same comparison process as the gloss retention is performed. Furthermore, the presence or absence of mold / algae is determined. For example, when mold is confirmed to be generated, the maintenance program may be changed to a pure acrylic paint having an antifungal effect.

  According to the present embodiment, by comparing the deterioration degree stored in the storage means 20 (FIG. 6) and the input deterioration degree (FIG. 5) for each of the azimuth planes, the display according to the comparison result is performed. Since the specification (FIGS. 2 and 8) of the paint to be used for each azimuth plane can be displayed on the display means 40 on the means 40, the specifications of the paint in accordance with the deterioration state of the building after the predetermined period. Can be requested. Furthermore, more appropriate paint specifications can be obtained by evaluating a plurality of items of the degree of deterioration for each azimuth plane.

  For example, as shown in FIG. 4 and FIG. 8, the control means 10 determines that the input east / west color difference deterioration degree “4” shown in FIG. If it is judged that the degree of deterioration of the color difference between the east and west faces stored in 20 is less than “6”, the paint has a durability lower than that of the currently used paint (Company A, acrylic silicon type, 10 years). (Company B, urethane system, 8 years) is determined as the specification of the east and west paints and is displayed on the display means 40.

  According to the present embodiment, by displaying on the display means 40 a specification of a paint having a durability lower than that of the paint currently used, it is more suitable when the progress of deterioration is slow in a certain azimuth plane. The paint specifications can be obtained.

  Also, for example, as shown in FIGS. 4 and 8, the control means 10 determines that the input deterioration degree (for example, the deterioration degree (color difference) of the north surface in the 10th year for Mr. B is “10”). ) Is greater than the degree of deterioration “9” stored in the storage means 20, the durability paint (Company B, The urethane system (8 years) is determined as the specification of the paint on the north surface, and is displayed on the display means 40.

  According to the present embodiment, the display means 40 displays a specification of a paint having a durability higher than that of the paint currently in use, so that it is more suitable when the progress of deterioration is fast in a certain azimuth plane. The paint specifications can be obtained.

  Further, as shown in FIG. 4, when the control means 10 determines that the input deterioration degree is different from the deterioration degree stored in the storage means 20, a predetermined period (10th year, 20th year, 25th It is characterized in that it is stored in the storage means 20 in order to update the specification (FIG. 8) of the paint for each azimuth plane used after the year) (FIG. 4 (a) is updated to FIG. 4 (b)). . Here, as shown in FIG. 4A, the basic maintenance program A0000 is registered as an initial setting for Mr. A until the 25th year. Therefore, at the time of the update, for example, when Mr. A's data does not exist in the maintenance programs A0001 and A0002, the data is added and updated in FIG.

  According to the present embodiment, the paint specification (FIG. 8) is updated (FIG. 4) by storing the paint specification (FIG. 8) for each azimuth plane used after a predetermined period in the storage means 20. Therefore, an appropriate maintenance program can be provided for each azimuth plane.

  Further, as shown in FIG. 4, the storage means 20 specifies the specifications of the paint corresponding to the amount of solar radiation for each azimuth plane in association with the area name of each area (A0000 in FIG. 2, A0001, A0002 in FIG. 8). And the specifications of the paint for each azimuth plane used after the predetermined period (A0000 in FIG. 2, A0001, A0002 in FIG. 8) for each property (“Mr. A”, “Mr. B”, “Mr. C” in FIG. ...)).

  According to the present embodiment, by storing the paint specifications (FIGS. 2 and 8) for each property (FIG. 4), it is possible to store the paint specifications according to the current state of each property. An appropriate maintenance program can be provided for each.

  Next, an example of the operation of the exterior material maintenance system will be described with reference to FIG.

  First, the control means 10 reads out the area name, the property name, the screen data for inputting the deterioration degree for each azimuth plane, and data such as the “OK” button from the storage means 20 and displays them on the display means 40. The control means 10 stands by until at least the area name is input by the input means 30 and the “OK” button is pressed (NO in step S1). If only the area name is input, the control means 10 extracts the maintenance program corresponding to the input area name from the basic maintenance program A0000 and displays it on the display means 40 (step S4). Further, when the deterioration level of one or more items for each property name and azimuth plane is input (YES in step S1, YES in S2), the deterioration level (FIG. 6) stored in the storage means 20 is input. The degree of deterioration (FIG. 5) is compared for each azimuth plane, and the specifications (A0001, A0002) of the paint to be used for each azimuth plane are displayed on the display means 40 according to the comparison result. (Step S4).

  According to the present embodiment, when only an arbitrary area name is input, by reading paint specific data corresponding to the amount of solar radiation for each azimuth plane from the storage means 20, the solar radiation for each azimuth plane is read. Since the specification of the paint corresponding to the amount can be displayed on the display means, the specification of the paint for each azimuth plane according to the amount of solar radiation different for each region can be obtained.

  Further, according to the present embodiment, when the property name and the deterioration degree are input, the deterioration degree (FIG. 6) stored in the storage unit 20 and the input deterioration degree (FIG. 5) are used as the direction. By comparing each surface, according to the comparison result, the display means 40 can display the specifications of the paint to be used for each azimuth plane (FIGS. 2 and 8) on the display means 40, It is possible to obtain the specifications of the paint in accordance with the deterioration state of the building after the predetermined period.
