Description

  The present invention relates to an ossuary tower that is installed outdoors and stores the remains of the deceased.

  The total population of Japan is expected to decrease to about 85 million people in the next 2060. Due to the increase in the number of deaths, the problem of “grave shortage” has surfaced in recent years, especially in urban areas. is doing. For example, as of 2014, the draw ratio of Aoyama Cemetery, a traditional cemetery (tombstone-type cemetery) in Tokyo, was 14.2 times, and the report of the Yokohama City Cemetery Problem Study Group (2010) According to September), by 2026, 94,000 divisions of cemetery will be additionally required in Yokohama City. Despite the increasing demand for graves, it is said that the biggest reason why the number of graves does not increase is the lack of land.

  Furthermore, in rural cemeteries that faced population decline earlier than in urban areas, there are many cases where owners of graves live in urban areas, and worshiping itself becomes increasingly difficult due to the aging of the owners. There is a current situation. In the future, it is assumed that compact cities will be promoted in local cities, and urban functions will be concentrated in a narrow area. May even be difficult to visit.

  In view of this situation, the report of the Yokohama City Cemetery Problem Study Group includes examples of “lawn-type cemetery”, “wall-type cemetery”, “tree / forest-type cemetery”, etc. that effectively use land in urban areas. It is disclosed. All of these are intended to make effective use of the land by densely arranging the graves in a narrow space, and the structure of the grave itself is simplified compared to the graves installed in the conventional gravestone-type cemetery. It will be possible to provide graves at a lower cost.

  As a configuration that enables dense arrangement of tombs in a narrow space, for example, it has a cylindrical storage mechanism that can be stored in a state where the urns used at the time of osteotomy are closely joined, and the main component is granite attached to the mechanism A capsule cemetery provided with a lid portion is disclosed (Patent Document 1).

  This capsule cemetery keeps the cost of the grave body low by securing only a minimum space for storing the urn by a cylindrical storage mechanism, and the cylindrical storage mechanism is embedded in the ground. It is said that maintenance is easy by using granite for the exposed lid.

Registered Utility Model No. 3206677

  According to Patent Document 1, although the capsule cemetery installed has only the lid exposed on the ground, the height from the ground surface to the top of the lid is never sufficient, and the name of the deceased Since the plate inscribed on the top is disposed on the upper surface of the lid, the plate (in the worst case, the entire lid) may be concealed by fallen leaves or earth and sand with the passage of time.

  Moreover, although the lid | cover part of the capsule graveyard of patent document 1 inclines with respect to a horizontal surface, the angle is loose and it becomes the structure which dirts, such as earth and sand and dust, adhere easily.

  Now, as mentioned above, when the graves are densely arranged in a narrow space in order to effectively use the land, worshipers such as bereaved families who visited for worship specify the position of the deceased's grave. In general, the higher the density, the more difficult it becomes. Moreover, since the grave forms in the “lawn-type cemetery” and “wall-type cemetery” usually have little personality, it is extremely difficult to reach the grave of the deceased, especially for those who visit for the first time. Furthermore, as described above, the information presentation medium (here, the plate) for identifying the grave can be concealed over time, which is one of the reasons why it is difficult to identify the grave.

  In this way, it is effective to use the location information of the grave to accurately guide the worshipers to the grave where personality is lacking and information for identifying the individual may be lost over time. Conceivable. However, the above-mentioned report and Patent Document 1 suggest nothing about the shape that the grave should have in order to configure the system for guiding the worshiper to the grave, and the system for guiding the worshiper to the grave. Absent.

  The present invention has been devised to solve such problems of the prior art, and its main purpose is to prevent the attachment of dirt, etc. It is to provide an ossuary tower that can be easily acquired.

  The present invention, which has been made to solve the above-mentioned problems, includes a cylindrical main body member extending upward and having a first internal space, and a stainless steel having a second internal space and attached to the upper end of the main body member. An ossuary tower that houses ashes in the first internal space in a state where the lid member is mounted on the main body member, the lid member projecting upwardly It is configured in shape, and at least a part of the lid member has a smooth outer surface, and the smooth surface is provided with a # 240 (fine-polishing finish: belt of about No. P200) defined by the Stainless Steel Association. Polished), # 320 (Polished finer than # 240: Polished with a belt of about P320), # 400 (Glossy near mirror surface, some streaks: Polished with P400 buff N) . No. 7 (quasi-mirror finish with high reflectivity (with polishing eyes): polished with a rotating buff No. P600), No. 7 This is an ossuary with a surface finish of 8 (finishing close to a mirror (without polishing eyes): final polishing by a mirror buff).

  This makes it difficult for dirt such as dust to adhere to the outer surface of the lid member, and the function of the smooth surface as the light reflecting surface can be maintained over a long period of time.

  In the present invention, when the ossuary tower is installed outdoors, the smooth surface reflects sunlight incident on the smooth surface upward.

  This makes it possible to substantially eliminate the restriction on the imaging position when an image is taken from above using a drone or the like to measure the position of the ossuary tower.

  In the present invention, the smooth surface is constituted by a part of a spherical surface.

  Accordingly, since the sphere is symmetric with respect to all the planes passing through the center thereof, the imaging conditions regarding the shape can be made almost the same regardless of the direction from which the lid member as the imaging target is imaged.

  In the present invention, the smooth surface is formed in a range of at least 45 ° ≦ α ≦ 90 °, where α is an angle from the horizontal plane passing through the center of the sphere constituting the spherical surface to the vertical direction. .

  Thereby, when sunlight enters the smooth surface, it becomes possible to always reflect sunlight upward at an arbitrary incident angle.

  In the present invention, the main body member is composed of a base portion buried underground and a ground portion exposed to the ground, and the ossuary tower is erected on the site by embedding the base portion underground. It was made to do.

  This makes it possible to reduce the installation cost of the ossuary tower.

  Further, according to the present invention, the above-mentioned ground portion is a concave portion in which a cross-sectional shape in a direction perpendicular to the direction in which the main body member extends upward is configured to have an annular shape, and a flat surface is formed on the outer periphery of the above-mentioned ground portion. Is provided.

  Accordingly, the concave portion can be formed by a simple method such as cutting.

  In the present invention, a flat porcelain tile with information on the deceased is attached to the concave portion constituted by a plane.

  This makes it possible to reduce the manufacturing cost of porcelain tiles.

  Thus, according to the present invention, dirt such as dust is less likely to adhere to the outer surface of the lid member of the ossuary tower, and the function of the smooth surface as the light reflecting surface can be maintained over a long period of time.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing an installation mode of an ossuary tower 1 according to the first embodiment of the present invention, and FIG. 2 is a side view of the ossuary tower 1 according to the first embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes an ossuary tower. The ossuary tower 1 is installed on a cemetery site 2 covered with, for example, lawn. As shown in FIG. 2, the ossuary tower 1 is composed of a main body member 3 and a lid member 4.

  The main body member 3 is formed of, for example, porcelain that extends upward and has a cylindrical shape, and includes a base portion 3a that is buried underground and a ground portion 3b that is exposed to the ground. The lid member 4 is made of stainless steel, for example. That is, the ossuary tower 1 is erected on the cemetery site 2 in such a manner that the ground portion 3b and the lid member 4 are exposed on the ground and the base portion 3a is buried underground. The ossuary 1 has a shape reminiscent of a rocket as a whole. Through this shape, the dead man's body (remains 9 (see Fig. 3)) is returned to the earth and its soul is sent to the sky. The idea that

  The porcelain constituting the main body member 3 is produced by reducing and firing mainly sand containing a glassy material as a main component, so that the iron oxide contained in the material is reduced and exhibits a color close to pure white. Since the porcelain is a dense sintered body, it is not hygroscopic and does not deteriorate over a long period of time, and is suitable as a material constituting the main body member 3 in terms of weather resistance and durability. Of course, ceramics can be used as the main body member 3. However, when using pottery, it is desirable to apply a substantial glass coat such as applying glaze on the surface and baking to suppress moisture absorption. The height L1 of the base portion 3a is, for example, 500 mm, the height L2 of the ground portion 3b is, for example, 500 mm, and the width L3 of the main body member 3 is, for example, 200 mm. The thickness of the cylindrical body member 3 is not particularly limited, but is about 10 mm in the first embodiment.

  The lid member 4 has a shell (warhead) shape that protrudes upward, and is made of a metal material such as stainless steel. Since stainless steel is excellent in formability and workability, and since chromium and oxygen contained in the stainless steel react with each other, it has a passive film of several nm on the surface and is excellent in weather resistance and durability. It is a material suitable for. The height L4 of the lid member 4 is, for example, 150 mm. The thickness of the lid member 4 is not particularly limited, but is about 5 mm in the first embodiment.

  The stainless steel constituting the lid member 4 can be selected from gloss or the like depending on the type of surface finish. In the first embodiment, # 240 defined by the Stainless Steel Association as “main surface finish of stainless steel” (fine-polished finish: polished with a belt of No. P200), # 320 (finer than # 240) Polishing finish: Polished with a belt of about No. P320), # 400 (Glossy near mirror surface, slight streaks: Polished with P400 buff), No. No. 7 (quasi-mirror finish with high reflectivity (with polishing eyes): polished with a rotating buff No. P600), No. 7 8 (finishing close to a mirror (without polishing eyes): final polishing is performed with a mirror buff) is preferable. As described above, the lid member 4 constituting the ossuary tower 1 of the first embodiment is surface-finished so that the outer surface thereof becomes the smooth surface 50 at least in part, and the smooth surface 50 is used as a light reflecting surface. Function.

  Of course, as long as at least the smooth surface 50 can be formed, the lid member 4 may be made of, for example, weathering steel as well as stainless steel. The weathering steel is a high-strength steel obtained by adding copper, chromium, phosphorus, etc. to ordinary steel and has excellent weather resistance and workability. Moreover, it may replace with a metal material and may use the ceramics which the glass coat was given to the porcelain and the outer surface at least as the cover member 4. In addition, the range which should comprise the smooth surface 50 among the cover members 4 is mentioned later.

  Thus, by making the outer surface of the lid member 4 the smooth surface 50, it becomes difficult for dust to physically adhere to the outer surface of the lid member 4, and the function as the light reflecting surface is maintained for a long time. Note that photocatalytic coating may be applied to the smooth surface 50. Titanium oxide contained in the photocatalyst paint exhibits hydrophilicity when irradiated with ultraviolet rays to form a thin film of water on the smooth surface 50 of the lid member 4, and further acts as a catalyst to generate active oxygen. Since active oxygen decomposes organic matter, the decomposed organic matter is swept away by rain force on the surface of the smooth surface 50 having hydrophilicity. Thus, the photocatalyst paint has a self-cleaning function, and the function of the smooth surface 50 as the light reflecting surface can be maintained for a long period of time. Moreover, since titanium oxide exhibits white color and reflects infrared rays, it is possible to effectively suppress the temperature rise on the outer surface and inside of the ossuary 1.

  FIG. 3A is a cross-sectional view of a bottomed III-III in the ossuary tower 1 according to the first embodiment of the present invention, and FIG. 3B is the ossuary tower 1 according to the first embodiment of the present invention. A bottomless type III-III sectional view and FIG. 4 are IV-IV sectional views of the ossuary tower 1 according to the first embodiment of the present invention. In addition, in FIG. 3 (a), FIG.3 (b), it does not show as a cross section about the storage thing (the remains 9 and the urn 10) accommodated in the main-body member 3 for easy understanding. Hereinafter, the structure of the ossuary tower 1 will be described in detail with reference to FIGS. 3 (a), 3 (b), and 4 together with FIG.

  3A, the upper end of the main body member 3 is provided with a notch 11 formed by removing the outer peripheral portion thereof by cutting, and the notch 11 is provided with a lid member. The lower end of 4 is fitted and the lid member 4 is attached to the main body member 3.

  The body member 3 is configured in a cylindrical shape with a bottom and includes an internal space 8a (first internal space) as a cavity, and the lid member 4 is configured in a cap shape and includes an internal space 8b (second internal space) as a cavity. ). In the internal space 8 a, the urn 10 in which the remains 9 are housed / sealed is stacked from below the main body member 3 upward. A grasping portion 12 is provided on the upper portion of the urn 10. A person who stores or removes the urn 10 removes the lid member 4 from the main body member 3 and inserts his / her arm from the upper end (opening) of the main body member 3. The provision of the portion 12 facilitates handling of the urn 10 and improves workability during storage and removal.

  As described above, in the ossuary tower 1, the lower end of the cap-shaped lid member 4 is fitted into the cutout portion 11 of the main body member 3, but rainwater or the like may enter from a minute gap in the fitting portion. In that case, a seal member (not shown) such as a packing made of rubber or the like may be disposed in the notch portion 11. Further, in order to prevent the lid member 4 from being easily removed from the main body member 3, for example, a thread (male thread) is formed on the outer peripheral surface of the notch 11, and the thread is formed on the inner surface near the lower end of the lid member 4. A projection to be guided may be provided, and the lid member 4 may be rotated to be attached to and detached from the main body member 3.

  In addition, although the material which comprises the urn 10 is not specifically limited, From the viewpoint of preserving the remains 9 over a long period of time, it is desirable that the urn 10 be composed of a metal material, porcelain, glass, or the like with low moisture and oxygen permeability. 10 may be filled with an inert gas such as a desiccant or nitrogen. The internal space 8b formed in the lid member 4 may be provided with a functional member including an electronic component as will be described later.

  On the side surface of the ground portion 3b, there is provided a porcelain tile disposing portion 5 formed of a concave portion whose side surface is cut. As shown in FIG. 4, the porcelain tile placement unit 5 forms a plane on the outer periphery of the ground portion 3b. The porcelain tile placement portion 5 is fitted with a plate-like porcelain tile 6 on which the name, name, photo, etc. of the deceased are printed and fixed by a weather-resistant adhesive. Since burn-in printing is excellent in durability and wear resistance, it is possible to maintain printed information and aesthetics semi-permanently even in an outdoor environment. Further, by configuring the porcelain tile disposition portion 5 as a flat surface, the porcelain tile 6 can be formed into a flat plate shape, and the manufacturing cost of the porcelain tile 6 can be reduced.

  A vent 7a is provided near the upper end of the main body member 3, and a vent 7b is provided near the lower end of the lid member 4 (see FIG. 2). As shown in an enlarged view in FIG. 3A, the inner space 8a of the main body member 3 communicates with the outside through the vent 7a, and the inner space 8b of the lid member 4 communicates with the outside through the vent 7b. Yes. The vent holes 7a and 7b are provided so as to be inclined downward from the internal spaces 8a and 8b to the outside. The vents 7a and 7b suppress the temperature rise in the internal spaces 8a and 8b of the ossuary tower 1 particularly in summer, and rainwater enters the ossuary 1 by providing the vents 7a and 7b at an angle. It is prevented.

  Of course, the number of the vent holes 7a and 7b and the locations of the vent holes 7a and 7b are not particularly limited. It is desirable to provide them close, and the vent 7b provided in the lid member 4 needs to be inclined downward from the internal space 8b to the outside, so it is provided in the vicinity of the lower end of the lid member 4 (that is, the vertical portion). Is desirable. Further, only one of the vents 7a and 7b may be provided, and the vents 7a and 7b themselves may not be provided in a region / region where the outdoor environment where the ossuary 1 is installed does not reach a high temperature. .

  A mesh-like sheet 15 made of, for example, stainless steel is disposed in the openings on the inner space 8a, 8b side of the vent holes 7a, 7b. The mesh sheet 15 prevents insects, dust, etc. from entering the internal spaces 8a, 8b from the outside.

  Now, in the first embodiment, the lower end of the main body member 3 of the ossuary tower 1 is bottomed as shown in FIG. 3 (a), but the lower end of the main body member 3 is bottomless as shown in FIG. 3 (b). Also good. In this aspect, the idea of returning to the earth is more recalled than the idea of preserving the remains 9.

  FIG. 5 is a side view illustrating the range of the smooth surface 50 provided on the lid member 4 of the ossuary tower 1 according to the first embodiment of the present invention. As shown in the drawing, the outer surface of the lid member 4 includes the upper hemisphere of the sphere S1, and when the angle from the horizontal plane passing through the center Osf of the sphere to the vertical direction is α, at least 45 ° ≦ of the upper hemisphere. The range of α ≦ 90 ° is defined as the minimum necessary range as the smooth surface 50 (hereinafter, simply referred to as “smooth surface range ARref”).

  The solar altitude on the earth's surface is in the range of 0 ° (for example, when the sun appears on the horizon) to 90 ° (for example, the spring / autumn day on the equator at the time of the south / middle). In this range, when the solar altitude is 0 °, sunlight that has entered the smooth surface range ARref from the direction D1 (horizontal direction) has a direction D2 (at a point PS1 on the spherical surface α = 45 ° above the center Osf of the sphere. Reflected in the vertical direction (directly above). Sunlight that has entered the smooth surface area ARref from the direction D3 when the solar altitude is 90 ° is reflected in the direction D1 at a point PS2 on the spherical surface that is α = 45 ° above the center Osf of the sphere. This means that when sunlight enters the smooth surface range ARref, the sunlight is always reflected upward (above the horizontal plane) at an arbitrary incident angle. Regardless, the sunlight reflected by the smooth surface area ARref can be observed from any position in the sky.

  FIG. 6 is an explanatory diagram illustrating an example in which sunlight incident on the smooth surface range ARref at an arbitrary angle is reflected at a specific angle. In FIG. 6, in the smooth surface range ARref as a part of the upper hemisphere of the sphere S1, the incident angle of sunlight with respect to the horizontal plane increases in the order of the direction D1, the direction D10, the direction D11, the direction D12, and the direction D3. In these incident angles, the points PS1, PS10, PS11, PS12, and PS13 where sunlight is reflected in the direction D2 (vertical direction (directly above)) exist. . That is, in the smooth surface range ARref, a part of sunlight is always reflected in the vertical direction regardless of the incident angle of sunlight. Thereby, for example, even if the solar altitude changes every day, the reflected sunlight can be observed from a certain direction (here, the vertical direction).

  As will be described later, sunlight reflected by the smooth surface range ARref is imaged from above by an imaging unit 21 (see FIG. 9) such as a camera. Since the sphere is symmetric with respect to all the planes passing through the center thereof, the imaging conditions relating to the shape are almost the same regardless of the direction in which the lid member 4 as the imaging target is imaged. In addition, by providing the cover member 4 with the smooth surface area ARref having the above-described characteristics, it is possible to capture the reflected light of sunlight incident on the cover member 4 as a directly reflected light component in a wider range, The imaging conditions for the individual imaging elements included in the imaging unit 21 are substantially the same in terms of the amount of incident light. That is, when an image for measuring the position of the ossuary tower 1 is taken from above using the drone 26 (see FIG. 9) or the like, it is possible to substantially relax the restriction of the imaging position.

  In the range other than the smooth surface range ARref in the lid member 4 (hereinafter sometimes referred to as the non-smooth surface range ARn), it is not necessary to have a sunlight reflecting function, and in the non-smooth surface range ARn. For example, it is possible to reduce the manufacturing cost of the lid member 4 by making the surface finish of stainless steel an inexpensive specification compared with the smooth surface range ARref. Of course, the surface finish of the non-smooth surface area ARn may be the same as the smooth surface area ARref. In this case, the smooth surface 50 is formed in the entire range of the lid member 4.

  FIG. 7A shows a first modification of the lid member 4 of the osteotomy tower 1 according to the first embodiment of the present invention, and FIG. 7B shows the lid member 4 of the osteotomy tower 1 according to the first embodiment of the invention. It is explanatory drawing which shows the 2nd modification of. The lid member 4 described with reference to FIG. 5 includes the entire upper hemisphere of the sphere S1, and the smooth surface 50 is formed on a part of the upper hemisphere. In the first modification shown in FIG. 7A, the diameter of the sphere S2 including the spherical surface on which the smooth surface 50 is formed is smaller than that of the sphere S1, and in the second modification shown in FIG. 7B, the smooth surface 50 is formed. The diameter of the sphere S3 including the spherical surface is made smaller than the sphere S2 shown in FIG.

  In the first and second modified examples, the lid member 4 includes a part of the upper hemisphere of the spheres S2 and S3, and as a result, the smooth surface range ARref included in the lid member 4 is the lid member 4 shown in FIG. It is configured to be smaller than the area. Also in these cases, the outer surface of the lid member 4 slides in a range of 45 ° ≦ α ≦ 90 °, where α is an angle in the vertical direction from the horizontal plane passing through the center Osf of the spheres S2 and S3. Since the surface range is ARref, sunlight incident on the smooth surface 50 of the lid member 4 can be effectively reflected upward.

  However, if the smooth surface range ARref is reduced in area, the luminous flux of reflected light decreases. In addition, from the viewpoint of reflecting sunlight evenly over a wide range, it is necessary to manage the curvature and surface roughness of the surface of the smooth surface 50 with high accuracy in the manufacturing process of the lid member 4, and therefore, the smooth surface range ARref. Should not be extremely small. Although depending on the imaging conditions, the diameter of the sphere on which the smooth surface area ARref is formed may be 100 mm or more.

  FIG. 8 is an explanatory view showing a third modification of the lid member 4 of the ossuary tower 1 according to the first embodiment of the present invention. In the lid member 4 shown in FIG. 8, the width occupied by the smooth surface range ARref is the same as the width L3 of the main body member 3, and the smooth surface range ARref is maximized in configuration. According to this configuration, the light flux of the reflected light is maximized, and the accuracy restriction when forming the smooth surface range ARref is alleviated.

  FIG. 9 is an explanatory diagram illustrating a process of acquiring the position information of the marker member 20 and the position information of the ossuary tower 1 in the guidance system Sy1 to the ossuary tower 1 according to the first embodiment of the present invention. As shown in the drawing, the guidance system Sy1 (hereinafter sometimes referred to as “guidance system Sy1”) to the ossuary tower 1 according to the first embodiment includes a first marker 20a, a second marker 20b, and a third marker 20c ( Hereinafter, when these are not distinguished, they may be simply referred to as “marker member 20”.), A plurality of ossuary towers 1, ossuary towers 1 and marker members 20 each having a smooth surface 50 formed on lid member 4 are viewed from above. An imaging unit 21 for imaging (aerial photography) is included.

  Each marker member 20 is provided with a marker position information acquisition unit 23 that acquires position information (latitude / longitude) based on a signal transmitted from the GPS satellite 22. The GPS satellite 22 here is assumed to be a quasi-zenith satellite used in the “MICHIBIKI” service scheduled to start operation on November 1, 2018, but may be an existing GPS satellite 22. . However, when the existing GPS satellite 22 is used, since the position measurement accuracy is as coarse as about 10 m, it cannot be used as it is for the guidance system Sy1 in consideration of the situation where the ossuary tower 1 is densely installed.

  The marker position information acquisition unit 23 receives a large amount (for example, at intervals of 1 second) of signals transmitted from the existing GPS satellites 22 over a predetermined period (for example, about 30 minutes), and averages a plurality of position information obtained from the signals. Thus, the position of the marker member 20 is measured with an accuracy (approximately 2 to 3 cm) equal to or higher than the accuracy (approximately 6 to 12 cm) assumed in the “MICHIBIKI” service (centimeter class positioning reinforcement service). It is possible. The position information of the marker member 20 measured by the marker position information acquisition unit 23 is sent to a network 24 such as the Internet based on a communication standard such as LTE (Long Term Evolution). Of course, a WiFi router may be provided in the vicinity of the marker member 20, and the acquired position information may be transmitted to the network 24 by a wireless LAN. The position information of each marker member 20 is sent to the server device 25 via the network 24.

  The imaging unit 21 is a camera mounted on the drone 26, for example, and includes a color image sensor (not shown). The imaging range A1 of the imaging unit 21 when performing aerial photography with the drone 26 includes the first marker 20a, the second marker 20b, the third marker 20c, and the plurality of ossuary towers 1, and each marker member 20 is captured by the imaging unit 21. In addition, a color still image including the ostium 1 for which position information is to be calculated is captured, and the captured image is transmitted to the server 25 via the network 24. Of course, the image sent to the server device 25 may be a color moving image. If the image is a color moving image, the server device 25 cuts out the frame image and acquires a still image. Further, each marker member 20 and the plurality of ossuary towers 1 do not have to be captured all in one image, and a color image obtained by combining a plurality of color images based on feature points and combining them. Should be obtained. Note that the use of the drone 26 is not indispensable for aerial photography. For example, the imaging unit 21 may be installed at a high place such as a building overlooking the entire cemetery.

  Each marker member 20 has a scattering surface on the surface of at least the side to be imaged (that is, the part facing the imaging unit 21) and is colored in a specific color. This coloring is applied in a color that is not normally adopted in the cemetery site 2 (see FIG. 1 and FIG. 10), and is red, for example, in the first embodiment. Since the surface of the marker member 20 is a scattering surface, the sunlight incident on the marker member 20 is scattered on the surface, and a red scattered light component (chromatic scattered light component) is imaged for the marker member 20. The image is taken by the unit 21.

  On the other hand, as described above, the lid member 4 of the ossuary tower 1 has the smooth surface 50, and sunlight is directly reflected on the slick surface 50. Therefore, the ossuary tower 1 is directly white (ie, achromatic). The reflected light component is imaged by the imaging unit 21.

  When a directly reflected light component of sunlight is incident on each pixel (Pixel) of the color image sensor constituting the imaging unit 21, normally, the charge accumulated in the pixel overflows and the pixel output is saturated. That is, if the RGB output of the color image sensor is, for example, 8 bits, each channel has a maximum value of 255 or an extremely large value close to the maximum value is output. On the other hand, when a chromatic color scattered light component (in this case, red) is input to the color image sensor, the value of R (Red) increases (although depending on the imaging conditions, the output generally does not saturate). , G (Green) and B (Blue) are output with small values. This makes it possible to clearly separate the marker member 20 and the ossicle 1 from the entire captured image.

  When the chromatic color scattered light component based on the marker member 20 and the achromatic color direct reflected light component based on the smooth surface 50 of the ossuary tower 1 are imaged across a plurality of pixels of the color image sensor constituting the imaging unit 21. The center of the pixel group may be regarded as corresponding to the positions of the marker member 20 and the ossuary 1.

  FIG. 10 is an explanatory diagram showing the positional relationship between the ossuary tower 1 and the marker member 20 in the guidance system Sy1 to the ossuary tower 1 according to the first embodiment of the present invention. In FIG. 10, the first marker 20a and the second marker 20b are arranged at the same longitude, and the second marker 20b and the third marker 20c are arranged at the same latitude. Here, the first marker 20a is arranged on the north side (the side where the latitude (north latitude) becomes larger) than the second marker 20b, and the third marker 20c is located on the east side (more longitude (east longitude) than the second marker 20b. It shall be arranged on the larger side.

As described above, the position information of each marker member 20 is acquired with high accuracy, and if an image including each marker member 20 and a plurality of ossuaries 1 is obtained, the number of pixels is counted. As shown in the drawing, the latitude and longitude of the ossuary tower 1 arranged at the position Pm can be obtained by simple calculation using the following equations.
Pm (latitude) = latitude of the second marker 20b + (latitude of the first marker 20a−latitude of the second marker 20b) × m2 / m1 (Expression 1)
Pm (longitude) = longitude of the second marker 20b + (longitude of the third marker 20c−longitude of the second marker 20b) × n2 / n1 (Expression 2)

  In the above description, for the sake of simplicity, the first marker 20a and the second marker 20b are arranged at the same longitude, and the second marker 20b and the third marker 20c are arranged at the same latitude. If the latitude and longitude of at least three marker members 20 are known, the side includes the point where the three marker members 20 are placed from the captured image, and the vertical side is the latitude. It is possible to calculate the position of each ossuary tower 1 with high accuracy based on the above (Formula 1) and (Formula 2) using three vertices of a rectangle parallel to the direction and the horizontal side parallel to the longitude direction as reference points. It is.

Control other components.

  The database 33 is constructed in a so-called large-capacity storage having a RAID (Redundant Arrays of Independent Disks) configuration or the like. The database 33 includes an ID (identifier) as an identifier assigned in advance to each ossuary 1, position information (latitude / longitude information) of the ossuator 1, personal information regarding the owner (right holder) of the ossuator 1, Information relating to the deceased in which the remains 9 are stored in the ossuary 1, the worship history of the owner, still images and videos showing the latest state of the ossuator 1, and the like are accumulated.

  Hereinafter, the operation of the guidance system Sy1 to the ossuary tower 1 according to the first embodiment will be described in detail with reference to FIG.

  First, an image of the imaging range A1 (see FIG. 9) including the ossuary tower 1 and the marker member 20 imaged by the imaging unit 21 and the position information of each marker member 20 measured by the marker position information acquisition unit 23 are the network 24. Is input to the data receiving unit 34. Based on the image of the imaging range A1 received by the data receiving unit 34 and the position information of each marker member 20, the ossuary tower position information calculating unit 32 performs the individual calcaneus based on the above-described (Expression 1) and (Expression 2). The position of the tower 1 is calculated and stored in the database 33 in association with the ID of each ossuary tower 1 determined in advance. That is, when the cemetery administrator designates the ossuary tower 1 based on the captured image, assigns an ID, and the ossuary tower position information calculation unit 32 calculates the position information of the designated ossuary tower 1, the ossuary tower 1 Are associated with the position information.

  The ossuary tower position information calculation unit 32 may calculate the position information of each ossuary tower 1 by independent hardware, or the server calculation unit 30 may execute the individual calculation based on a program stored in the server storage unit 31. The position of the ossuary tower 1 may be calculated.

  Now, a person who wants to use the ossuator 1 (a person who buryes the deceased's remains 9; hereinafter referred to as the “owner”) purchases the ownership (use right) of the ossuary 1 from the cemetery operator. The cemetery operator presents the position of the unused ossuary tower 1 to the (future) owner, and the (future) owner selects the desired ossuary tower 1 from the unused ossuary tower 1 To do. Based on this selection act, the cemetery administrator will assign the ID given to the ossuator 1 in advance and the position information of the ossuator 1 and the owner's personal information (ie, name, address, photo, contact information, owner And stores the information in the database 33 in association with the mail address of the information terminal 29 possessed. Furthermore, the owner notifies the cemetery operator of information about the deceased (ie, name, command name, photo, etc.). The cemetery operator stores this in the database 33 in association with the name of the owner, for example. Further, the cemetery operator refers to the position information of the ossuator 1 from the ID of the ossuary 1, and takes pictures and videos of the ossuator 1 for each season, and associates this with the ID (or owner's name). May be stored in the database 33.

  The digital signage 28 installed at the cemetery information center 27 in the cemetery is composed of a large display using, for example, a liquid crystal panel or an organic EL panel, a touch panel (not shown) superimposed on the display, and the like. The digital signage 28 can transmit and receive information to and from the server device 25. When the owner of the ossuary 1 or a worshiper familiar with the deceased visits the ossuator 1, when the worshiper operates the touch panel of the digital signage 28 and enters, for example, the name of the owner, the name of the owner The information is transmitted to the server device 25, and the server calculation unit 30 accesses the database 33 to extract information associated with the owner (including the position information of the ossuary 1) and superimpose it on the map information of the cemetery site 2. The image is generated and transmitted to the digital signage 28. Thereby, the worshiper can grasp the approximate position of the ossuary 1 to be worshiped.

  That is, the guidance system Sy1 comprehensively manages and processes data having various information related to the position of the ossuator 1, and visually displays the data, so-called geographic information system (GIS). But there is.

  Now, the worshiper installs an application (hereinafter also referred to as “guidance app”) that guides the worshiper to the ossuary 1 on the information terminal 29 such as a smart phone or a tablet possessed by the worshiper. When the guide application is activated, a display screen (not shown) of the information terminal 29 has a search screen for inputting search items such as the owner of the ossuary 1, the name of the deceased, and an ID given in advance to the ossuary 1. Is displayed. When the worshiper inputs at least one of the search items, a character string or a value (hereinafter sometimes referred to as “value”) corresponding to the search item is transmitted to the network 24 via a wireless LAN such as LTE or WiFi. Then, the search item receiving unit 36 of the server device 25 receives the search item and the value via the network 24.

  The server computing unit 30 searches the database 33 based on the value (for example, the name of the owner) received by the search item receiving unit 36, and extracts the position information of the ossuary tower 1 owned by the owner. The server calculation unit 30 transmits the extracted position information of the ossuary tower 1 to the network 24 via the ossuary tower position information transmission unit 35, and the position information of the ossuary tower 1 is transmitted to the information terminal 29 via the network 24. Is done.

  The guidance application that is operating on the information terminal 29 always receives a signal from the GPS satellite 22, and the guidance application is based on the signal received from the GPS satellite 22 and the position information of the information terminal 29 (that is, the position information of the worshiper). (Here, position Ps)) is calculated, and the position information (here, position Pd) of the ossuary tower 1 received from the server device 25 is associated (that is, the two positional relationships can be understood) superimposed on the map. To do. Since the position information of the worshipers is periodically updated, the worshipers are guided to the ossuary 1 while checking their own position Ps and the position Pd of the ossuary 1.

  Thus, the guidance system Sy1 to the ossuary tower 1 according to the first embodiment of the present invention is provided with a plurality of marker members 20 and the marker members 20, and acquires marker position information for acquiring the position information of the marker members 20. Based on the part 23, the imaging part 21 that images both the ossicle tower 1 and the marker member 20 from above, the position information of the marker member 20 acquired by the marker position information acquisition part 23, and the image obtained by the imaging part 21 The ossu tower position information calculation unit 32 for calculating the position information of the ossuator 1, the information terminal 29 owned by the worshiper of the ossuator 1, and acquiring the worshiper position information, and the ossu tower position information calculation unit 32 Ossifying tower position information transmitting unit 35 for transmitting the position information of the ossuary tower 1 obtained in the above to the information terminal 29, and the information terminal 29 associates the position information of the worshiper with the position information of the ossuary tower 1. To display.

  Furthermore, in the guidance system Sy1 to the ossuary tower 1 according to the first embodiment of the present invention, a colored scattering surface is formed on at least the surface of the marker member 20 facing the imaging unit 21, and imaging is performed. The part 21 picks up the chromatic color scattered light component scattered on the surface of the marker member 20 for the marker member 20 and is reflected by the smooth surface 50 formed on the lid member 4 of the ossuary tower 1 for the ossuary tower 1. An achromatic direct reflected light component is imaged.

  In the first embodiment, as shown in FIG. 11, the information terminal 29 possessed by the owner of the ossuator 1 is connected to the server device 25 via the network 24. Of course, the server device 25 can be accessed even by a PC (personal computer) or tablet other than the information terminal 29 in terms of configuration. The server computing unit 30 manages the access right to the database 33, and the owner of the ossuator 1 can access the database 33 by inputting, for example, a predetermined password on the screen of a tablet or the like.

  As described above, the database 33 accumulates, for example, seasonal ossuary tower 1 photographs and moving image data imaged by the cemetery operator. The owner of the ossuary tower 1 It is possible to browse the latest images. Thus, even if it is difficult for the owner of the ossuary 1 to visit the grave or the like, the image of the ossuary 1 that he owns can be viewed from a remote home, for example, and can be visited in a pseudo manner.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described. FIG. 12 is a perspective view showing a configuration of the ossuary tower 1 according to the second embodiment of the present invention. As shown in the figure, the ossuary tower 1 according to the second embodiment also includes a main body member 3 and a lid member 4 attached to the upper end of the main body member 3, and a smooth surface 50 is formed on the surface of the lid member 4. The basic configuration is the same as that of the ossuary 1 described in the first embodiment. However, in the second embodiment, the ossuary tower 1 includes a light emitting unit 40 at the top of the lid member 4, and the ossuary tower control unit 41 is housed in the internal space 8b of the lid member 4 (see also FIG. 3). This is different from the first embodiment.

  The light emitting unit 40 includes a light emitting element (not shown) such as an LED (light emitting diode) disposed in an opening (not shown) provided on the top of the lid member 4. The lid member 4 is sealed by mounting a resin plate (not shown) having a shape constituting a continuous surface. The plate material is preferably made of glass in consideration of weather resistance, but may be made of, for example, polycarbonate which is not easily deteriorated by ultraviolet rays. The side of the internal space 8b of the plate material is processed into a rough surface and scatters the light emitted from the light emitting element. In this way, the light emitting unit 40 is processed to scatter light in consideration of the visibility from all directions based on the viewpoint of accurately guiding the worshiper to the ossuary 1 and is applied to the top of the lid member 4. Has been placed.

  Hereinafter, the range in which the light emitting unit 40 should be provided in the lid member 4 will be described with reference to FIG. As described in detail in the first embodiment, a smooth surface 50 is formed on a part of the lid member 4, and the smooth surface 50 has a function of reflecting sunlight upward (hereinafter referred to as “sunlight reflecting function”). Have). Since the light emitting unit 40 is provided at the top of the lid member 4, the range in which the light emitting unit 40 is installed is determined so that the sunlight reflecting function is always ensured even when the solar altitude is particularly large. Should.

Assuming the day of the summer solstice when the solar altitude (south / middle altitude) is maximum, for example, the south / middle altitude Hs in Tokyo (latitude (north latitude) = 35 °) is approximately as follows.
South and Middle Altitude Hs (Tokyo) = 90 ° -35 ° + 23 ° = 78 ° (Formula 3)
In Naha City (latitude (north latitude) = 26 °), it is approximately as follows.
South and Middle Altitude Hs (Naha City) = 90 ° -26 ° + 23 ° = 87 ° (Formula 4)

In Japan, even in Naha City, where the altitude is higher in South China, in order to always ensure the sunlight reflecting function of the ossuator 1 according to the present invention, as shown in FIG. Of these, when the angle from the horizontal plane passing through the center Osf of the sphere toward the vertical direction is β, the light emitting unit 40 may be provided in the range of 87 ° ≦ β ≦ 90 °. To generalize this, when the latitude of the place where the ossuator 1 is installed is Lat1, the range of β in which the light emitting unit 40 should be installed in the lid member 4 is approximately as follows.
(South / South altitude Hs (Lat1) = 90 ° −Lat1 + 23 °) ≦ β ≦ 90 ° (Equation 5)
Thus, if the light emission part 40 is provided in the range of (beta), the sunlight reflecting function of the ossuary tower 1 will be ensured reliably irrespective of the date.

  FIG. 13: is a block block diagram which shows the structure of the guidance system Sy2 to the ossuary tower 1 which concerns on 2nd Embodiment of this invention. The guidance system Sy2 includes a light emitting unit 40, an ossuary control unit 41, and an information terminal 29 possessed by worshipers who visit the ossuator 1. The ossuary control unit 41 includes a light emission control unit 42, a transmitter 43, a receiver 44, an ossuary tower calculation unit 45, and an ossuary storage unit 46, and these components are connected by a bus 47. At the same time, it is driven by a battery power source (not shown). This battery power source is replaced when a survivor of the bereaved family visits the grave or the cemetery administrator replaces the battery power source.

  The ossuary tower calculation unit 45 is constituted by a CPU or the like, and controls other components according to a control program stored in a ROM, a RAM, etc. constituting the ossuary storage unit 46. The light emission control unit 42 includes an LED driver, and the ossuary calculation unit 45 controls the turning on and off of the light emitting unit 40 by outputting ON (1) / OFF (0) state signals to the light emission control unit 42. To do.

  The transmitter 43 is a radio beacon that transmits / transmits unique identification information of the transmitter 43 stored in advance in the ossuary storage unit 46, and typically corresponds to a device called a Beacon (hereinafter referred to as “beacon”). The transmitter 43 may be referred to as “Beacon”). A predetermined control unit (not shown) is incorporated in the transmitter 43, and the transmitter 43 transmits unique identification information at a predetermined cycle under the control of the control unit. The unique identification information is also stored in the information terminal 29 held by the owner of the ossuator 1. Of course, the unique identification information is stored in the database 33 (see FIG. 11) described in the first embodiment, so that the owner of the ossuator 1 can access the database 33 from the information terminal 29 and take it into the information terminal 29. It may be.

  The transmitter 43 includes a communication module (not shown) compliant with, for example, the BLE (Bluetooth (registered trademark) Low Energy) standard, and the unique identification information associated with each ossuary tower 1 is, for example, every 10 to 20 seconds. Periodically (advertise). The unique identification information is generally composed of three identifiers called proximity UUID, major, and minor.

  The proximity UUID is expressed by a 128-bit UUID (Universally Unique Identifier), and is used here as an identifier of a service provided by the cemetery operator. The data that Beacon advertises always includes a proximity UUID. Major is a value expressed in 16 bits, and is used as a unique identifier for each Beacon having the same proximity UUID. minor is a value expressed in 16 bits and is used as a Beacon identifier having the same proximity UUID and major. In the BLE standard, whether or not major and minor are included in the information advertised by Beacon is arbitrary, but in the guidance system Sy2 to the ossuary tower 1 according to the second embodiment, beacon is at least Proximity UUID and major are transmitted so that the ossuator 1 corresponding to each beacon can be identified.

  The reach of radio waves transmitted from the transmitter 43 is about 20 to 30 m. However, the reach may be about 50 m depending on environmental conditions such as when the line of sight is good. The information terminal 29 includes a receiving module (not shown) compliant with the BLE standard, and extracts the values of proximity UUID, major, and minor (that is, unique identification information) when receiving information advertised by the transmitter 43. When the unique identification information stored in advance in the information terminal 29 matches the received unique identification information, the information terminal 29 returns an acknowledge signal to the ossuary tower control unit 41.

  When receiving the acknowledge signal (predetermined information), the receiver 44 of the ossuary control unit 41 notifies the ossuary calculation unit 45 that the reception has been completed. Receiving this notification, the ossuary calculation unit 45 outputs an instruction to the light emission control unit 42 to turn on the light emission unit 40, and the light emission control unit 42 having received the instruction outputs the LED constituting the light emission unit 40 to a predetermined value. Flashes with a pattern. The blinking of the LED continues until the acknowledge signal is never received in a predetermined period (for example, 3 minutes).

  As described above, in the guidance system Sy2 to the ossuary tower 1 according to the second embodiment, when the worshiper approaches the ossuary tower 1, the light emitting unit 40 emits light and is associated with the owner of the ossuary tower 1 (or associated with the ossuary tower 1). The worshiper who can store the unique identification information in the information terminal 29 owned by him / her) is surely guided to the ossuary 1 at night.

  The ossuary tower 1 according to the present invention assumes that a large number of ossuary towers 1 are densely arranged in order to effectively use a narrow land. However, as described above, the reach of radio waves transmitted by the transmitter 43 is as follows. However, since the distance from the ossuary tower 1 to the worshiper is large, it becomes difficult for the worshiper to easily find the ossuary tower 1 even if the light emitting unit 40 emits light.

  Therefore, in the ossuary tower 1, the main body member 3 is made of an insulating material, and the lid member 4 is made of a conductive material (here, stainless steel), and at least the transmitter 43 is placed in an internal space 8 b provided in the lid member 4. It is arranged. By doing so, the radio wave transmitted from the transmitter 43 is shielded by the lid member 4 and propagated only from the main body member 3. As a result, the reach of the radio wave (that is, the range in which the information terminal 29 owned by the worshiper can receive the advertisement) is limited, for example, within 10 m to the ossuary tower 1 where the worshiper worships. When the distance to the tower 1 is close, the light emitting portion 40 of the ossuary tower 1 is caused to emit light, and the guiding function to the ossuary tower 1 can be exhibited.

  As mentioned above, although the ossuary tower 1 and the guidance system Sy1, Sy2 to the ossuary tower 1 according to the present invention have been described in detail based on specific embodiments, these embodiments are merely examples, and the present invention is not limited to these. It is not limited by the embodiment. For example, the guidance system Sy3 up to the ossuary tower 1 having the guidance system Sy1 described in the first embodiment and the guidance system Sy2 described in the second embodiment may be configured.

  The ossuary tower and the guide system to the ossuary tower according to the present invention are configured to prevent dirt from adhering and to be able to easily acquire position information even if a long period of time has elapsed after installation, and acquisition Since it is possible to construct a guide system to an ossuary tower that accurately guides worshipers to the ossuary tower based on the positional information, it is suitable for applications such as cemeteries in urban areas where many ossuary towers are installed. be able to.
