  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram illustrating an example of a building maintenance management system according to an embodiment of the present invention.

  The building maintenance management system according to the present embodiment is connected to a HEMS (Home Energy Management System) 30 that is a control device that calculates the amount of sunlight irradiated from the power generation amount of the solar battery panel 20 installed in the building 10. Yes.

  The building 10 has a tile on a roof 16 on which a solar panel 20 is installed, and is surrounded by an outer wall 14.

  A rain gutter 18 is provided at an eave corresponding to the tip of the roof 16.

  These roof tiles, rain gutters 18 and outer walls 14 are deteriorated by exposure to the external environment, but deterioration due to sunlight irradiation is particularly problematic.

  The outer wall 14 is painted to improve aesthetics and weather resistance, but the synthetic resin constituting the coating film is easily deteriorated by sunlight, particularly ultraviolet rays contained in the sunlight. The synthetic resin that makes up the gutter also deteriorates when exposed to sunlight.

  In recent years, there is a roof tile that has been surface-treated by painting instead of glaze, and the surface coating film of this type of roof tile deteriorates due to the irradiation of sunlight.

  The building maintenance management system according to the present embodiment calculates the amount of irradiation of solar light from the amount of power generated by the solar battery panel 20, and the calculated amount of irradiation is allowed for each member such as the roof tile, the outer wall 14, and the rain gutter 18. By comparing with the amount of irradiation, it is estimated whether or not each member needs to be repaired, and then when repair or maintenance is required.

  In addition to the solar battery panel, the building maintenance management system according to the present embodiment separately measures a device that can measure the amount of sunlight irradiated and measure the cumulative amount of sunlight irradiated from the start of the measurement. You may have.

  In addition, as shown in FIG. 1, the building maintenance system according to the present embodiment includes an ultraviolet ray meter 22 that measures the amount of ultraviolet light in sunlight, an outside air thermometer 24, a hygrometer 26, and a building 10. It is further provided with measuring means such as a vibrometer 28 that senses the shaking of the device, and using the results measured by these measuring means, it is estimated whether or not each member needs to be repaired, and when repair or maintenance is required next May be.

  FIG. 2 is a block diagram showing a schematic configuration of the HEMS 30 which is a control device according to the present embodiment.

  As shown in FIG. 2, the HEMS 30 includes a CPU 36, a ROM 38, a RAM 40, and an input / output port 42. These include a bus 44 such as an address bus, a data bus, and a control bus. Are connected to each other.

  A display unit 46, an operation unit 48, and a memory 50 are connected to the input / output port 42 as various input / output devices. The display unit 46 and the operation unit 48 are integrally configured, and a touch panel provided on the display unit 46 can be applied to the operation unit 48.

  The display unit 46 may be capable of displaying whether or not each member needs to be repaired, and when repair or maintenance is required next.

  In the memory 50, the irradiation amount of the solar ray is calculated from the power generation amount by the solar battery panel 20, and the calculated irradiation amount is compared with the irradiation amount allowed for each member such as the roof tile, the outer wall 14, and the rain gutter 18. According to the above, a program for estimating whether or not each member needs to be repaired, and the time when repair or maintenance is required next, a durability information table for each member that describes the amount of sunlight allowed for each member, and the location of the member , The degree-of-influence influence degree table that describes how much sunlight irradiated by the installation angle affects the members, maintenance management history information that records the repair or maintenance history for each part of the building, and the program is executed For this purpose, various information and the like are stored.

  The HEMS 30 expands the program stored in the memory 50 to the RAM 40 or the like and executes it by the CPU 36 so as to estimate whether or not each member needs to be repaired, and then when repair or maintenance is required next. It has become.

  Further, the solar cell panel 20, the ultraviolet ray meter 22, the outside air thermometer 23, the hygrometer 26, and the vibration meter 28 are connected to the input / output port 42.

  FIG. 3 is a diagram showing an example of the durability information table for each member describing the irradiation amount of sunlight allowed for each member according to the present embodiment.

  The roof tiles and outer walls illustrated in FIG. 3 are painted on the surface, the rain gutters are made of vinyl chloride resin, and the waterproof sheet is a type of polyester long fiber nonwoven fabric used for building rooftops, etc. impregnated with asphalt. It is.

  The numerical value shown in FIG. 3 is an example of the cumulative irradiation amount until these members deteriorate due to the irradiation of sunlight. Even if it is the same type of tile, rain gutter, outer wall and waterproof sheet as shown in FIG. 3, there is a difference in durability against sunlight depending on the product.

  FIG. 4 is a diagram showing an example of the influence degree table for each azimuth part describing how much sunlight irradiated by the installation location and installation angle of the member according to the present embodiment affects the member.

  Even if the buildings have the same roof, the amount of irradiation with sunlight differs depending on the east side, south side, west side, and north side. Also, the roof tiles, gutters, and outer walls are not placed horizontally just under the sun in the south, but are installed at a predetermined angle with respect to the horizontal plane, so the amount of solar radiation varies depending on the installation angle. Come.

  FIG. 4 shows the influence coefficient for each azimuth part indicating how much the irradiation of the sunlight rays in each part is influenced from the azimuth of each part and the installation angle of each part.

  When the member is facing south and placed horizontally, the factor of “1.00” is calculated on the assumption that the irradiation of sunlight affects the member approximately 100%.

  In other cases, the extent to which the sun rays affect the part of the member is determined from the direction and angle at which the member is installed.

In the present embodiment, the irradiation amount of solar rays per m ² is calculated from the power generation amount of the solar battery panel 20, but each of the members is obtained by multiplying the calculated irradiation amount by the coefficient shown in FIG. The amount of sunlight irradiated to the site can be calculated.

  FIG. 5 is a diagram illustrating an example of maintenance management history information in which a repair or maintenance history for each part of the building according to the present embodiment is recorded.

  After the building is completed, the necessity of repair of each member is estimated based on the cumulative amount of solar radiation from the completion of the building, and the next time when repair or maintenance is required. When the part is repaired, it is necessary to determine whether or not the repair of each member is necessary based on the cumulative amount of sunlight irradiated after the repair.

  In this embodiment, when repairs such as repainting or replacement of parts are performed for each part, the date related to the repair is recorded, and the last repair for parts that have been repaired The necessity of repair of a member etc. is judged based on the irradiation amount of the accumulated solar ray from the date concerning.

  FIG. 6 is a flowchart relating to the control of the building maintenance management system according to the present embodiment.

In step 600, the amount of sunlight irradiated per m ² is calculated from the amount of power generated by the solar cell panel 20 for one day.

The amount of power generation per m ² is obtained from the area of the solar cell panel 20 and the amount of power generation for one day of the day, and further, the irradiation amount of solar rays per m ² can be calculated from the conversion efficiency of the solar cell panel.

For example, in a solar panel with an area of 10 m ² , if the daily power generation amount is 4.200 kwh, 1 kwh = 3.6 × 10 ⁶ J, so the daily power generation amount is 15.12 MJ, The daily power generation per m ² is 1.512 MJm ⁻² .

If the conversion efficiency of the above solar cell panel is 15%, the irradiation amount per m ² of the sunlight of the day is calculated to be 10.08 MJm ⁻² .

In step 602, the cumulative amount of sunlight irradiated per m ² after the building 10 is completed is calculated. Specifically, the amount of sunlight irradiated per m ² calculated in step 600 can be stored in the memory 50 or the like of the HEMS 30 and the total can be calculated.

  Note that the cumulative amount of sunlight irradiated calculated in step 602 is the cumulative amount after the solar panel 20 starts generating power, but from the completion of the building 10 until the solar panel 20 starts generating power. The time difference is slightly smaller than the time until each part of the building 10 requires repair. Therefore, in the present embodiment, the time when the building 10 is completed and the time when the solar panel 20 starts generating power may be regarded as the same period.

In step 604, the sunlight calculated in step 602 is the coefficient of the degree-by-direction-part influence degree table that describes how much sunlight irradiated on the member depends on the member installation location and installation angle shown in FIG. The amount of sunlight irradiated per m ² of each part from the completion of the building 10 is calculated by multiplying the accumulated amount of irradiation.

In step 606, with reference to the maintenance management history information in which the repair or maintenance history for each part of the building according to the present embodiment shown in FIG. 5 is recorded, m of each part after completion or from the last repair. ^The amount of sunlight irradiated per ² is calculated.

The irradiation amount of sunlight per m ² of each part after completion is the numerical value calculated in step 604. In addition, the amount of sunlight irradiated per m ² of each part from the last repair is divided by the daily amount of sunlight per m ² of each part since completion, and the numerical value calculated on the daily basis is the last. It may be calculated by multiplying the number of days from the date of repair to the present.

  In step 608, the numerical value calculated in step 606 is compared with the numerical value in the durability information table for each member describing the irradiation amount of sunlight allowed for each member according to the present embodiment shown in FIG.

  In step 610, it is determined whether or not the numerical value calculated in step 606 is equal to or greater than the numerical value in the member-specific durability information table. If the determination is affirmative, in step 612, the portion requiring repair is displayed on the display unit 46 of the HEMS 30. To display.

Further, in step 614, the period until the next repair is calculated for other parts that do not require immediate repair. The calculation method of the period is shown in Fig. 3 as an example, the cumulative amount of sunlight irradiation per m ² of each part after completion or the last repair, and the number of days from the last repair to the present. It is conceivable to calculate from the numerical values described in the individual member durability information table.

For example, when a waterproof sheet installed horizontally one year after the last repair is irradiated with 3.65 GJm ^-2 of sunlight, the allowable irradiation amount of sunlight on the waterproof sheet is 36. Since it is 5GJm- ² , it turns out that the said waterproof sheet requires repair in nine years.

  In step 616, the result calculated in step 614 is displayed on the display unit 46 of the HEMS 30, and the series of processing ends. In this case, it may be displayed how many years later the repair is required, but the time when the repair is actually required may be displayed in the date.

In step 606, the amount of sunlight irradiated per m ² of each part from the last repair is divided by the day and the amount of sunlight irradiated per m ² of each part from the completion of construction is calculated on a daily basis. Was calculated by multiplying the number of days from the date of the last repair to the current date, but the amount of sunlight per m ² stored in the memory 50 etc. You may obtain | require by integrating | accumulating for every site | part from the date to the present.

  As described above, according to the building maintenance system according to the present embodiment, not only the repair history of each part of the building but also the necessity of repair of each part based on the actually irradiated solar rays. Or, since it is possible to specify the time when repairs are required, it is possible to maintain the building in consideration of the external environmental factor of sunlight.

  Furthermore, by combining a UV meter, outdoor thermometer, hygrometer, or vibration meter with the building maintenance system of this embodiment, not only sunlight but also the direct effects of UV, temperature, humidity, earthquakes, etc. There is an effect that it is possible to maintain the building in consideration of the influence.

  In this case, in addition to the amount of irradiated ultraviolet rays, it may be determined that repair is required even if the cumulative period of recording of humidity, temperature difference, fluctuation, etc. exceeding a predetermined threshold exceeds a predetermined value.

  In particular, since a waterproof sheet or an eaves under a roof tile is difficult to be exposed to sunlight, the time when repair is necessary may be determined from changes in humidity, temperature, shaking, and the like.
