Description

[Technical Field]

[0001] The present invention relates to a damage representation system and a damage representation diagram. [Background technology]

[0002] Traditionally, infrastructure inspection projects have used deformation diagrams, which record the damage status of structures obtained through visual and tactile inspection, and assessment diagrams, which evaluate the degree of deterioration of each structure's component. As shown in Figure 3, these deformation diagrams are created on a blank white drawing of the structure 800, recording the damage at regular intervals, such as every one to five years, using the same scale as the drawing, to confirm the progression of the damage. The deformation diagrams are created by inspectors copying sketches and photographs taken at the inspection site. Furthermore, as shown in Figure 4, the assessment diagrams are created by inspectors assessing the degree of deterioration of each component of the structure 800 (beams 820, 830, etc.), color-coding them according to the degree of deterioration, and are used by managers to determine the timing and scope of repair work.

[0003] However, the problem with the deformation diagram shown in Figure 3 is that it is created by inspectors copying sketches and photographs taken at the inspection site in an attempt to reproduce the actual state of damage (location, size, etc.) as accurately as possible, which means it takes time and effort. Also, while the judgment diagram shown in Figure 4 can evaluate the overall deterioration of a component, it does not provide as much information as the deformation diagram, so it has the problem of not being able to grasp the location of damage within the component. Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above problems, the present invention provides a damage representation system and a damage representation diagram that show information about damage to a structure in an easier way to understand. [Means for solving the problem]

[0005] In order to solve the above problems, the damage representation system of the present invention is a damage representation system for a structure, comprising: a display unit that displays the structure on a display surface; a damage information recording unit that records the position and damage state of the damaged area on the structure; and a damage area display unit that displays information about the damaged area on the display surface, wherein the damage area display unit generates a damage area display that connects the position of the damaged area obtained from the damage information recording unit with a reference point of a position relative to the structure, the damage area display unit changes the appearance of the damage area display unit in accordance with the damage state obtained from the damage information recording unit, and the damage area display unit displays the damage area display on the display surface.

[0006] According to the above features, by using a damage area indicator, it is possible to indicate damaged areas in a structure in a simple manner, and furthermore, information about the damage (degree of deterioration, type and extent of damage, and other arbitrary information) can be grasped by the appearance (color, density, shape) of the damage area indicator.

[0007] Furthermore, the damage representation system of the present invention is characterized in that the damage area display unit generates a first damage area indicator on one side of the structure, connecting a first reference point located relative to the structure and the position of the damage area acquired from the damage information recording unit, and the damage area display unit generates a second damage area indicator on the opposite side of the structure, connecting a second reference point located relative to the structure and the position of the damage area acquired from the damage information recording unit, and the damage area display unit shows the first damage area indicator and the second damage area indicator from both sides of the structure on the display surface.

[0008] According to the above features, the first damage area indicator and the second damage area indicator can indicate in a simple manner that there is damage on both sides of the structure, and furthermore, it becomes possible to make advanced judgments that correlate the damage on both sides.

[0009] Furthermore, the damage representation diagram of the present invention is a damage representation diagram of a structure, wherein the structure is shown on a display surface, a damage area indicator is shown on the display surface connecting the position of the damaged area on the structure with a reference point at a position relative to the structure, and the appearance of the damage area indicator is changed in accordance with the damage state of the damaged area on the structure.

[0010] According to the above features, by using a damage area indicator, it is possible to indicate damaged areas in a structure in a simple manner, and furthermore, information about the damage (degree of deterioration, type and extent of damage, and other arbitrary information) can be grasped by the appearance (color, density, shape) of the damage area indicator.

[0011] Furthermore, the damage representation diagram of the present invention is characterized in that, on one side of the structure, a first damage area indicator is displayed on the display surface, connecting a first reference point located relative to the structure and the position of the damaged area, and on the opposite side of the one side of the structure, a second damage area indicator is displayed on the display surface, connecting a second reference point located relative to the structure and the position of the damaged area, and the first damage area indicator and the second damage area indicator are displayed on the display surface from both sides of the structure.

[0012] According to the above features, the first damage area indicator and the second damage area indicator can indicate in a simple manner that there is damage on both sides of the structure, and furthermore, it becomes possible to make advanced judgments that correlate the damage on both sides. [Effects of the Invention]

[0013] The damage representation system and damage representation diagram of the present invention allow information about damage to a structure to be displayed in an easier and more understandable manner. [Brief explanation of the drawings]

[0015] 100 Display 200 Damage Information Recording Unit 300 Damage area display section 710 Damage area indicator 800 Structures 900 Damage Expression System P1 reference point DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the mechanisms of the damage representation system described in each drawing are merely examples, and the present invention is not limited to these.

[0017] First, Fig. 1 shows a conceptual diagram of a damage representation system 900 of the present invention. As shown in Fig. 1, the damage representation system 900 includes a display unit 100 having a display surface, a damage information recording unit 200, and a damaged area display unit 300. The damage representation system 900 is implemented in a portable computer, with the display unit 100 being realized as a display surface such as a display connected to the portable computer, the damage information recording unit 200 being realized as a storage device such as a ROM or HDD built into the portable computer, and the operation of the damaged area display unit 300 being realized by a CPU (central processing unit) built into the portable computer and a program that executes the processing of the damaged area display unit 300.

[0018] The damage information recording unit 200 records the location and state of damage of the damaged portion of the structure input by the inspector. For example, the inspector looks at the actual structure or at an image of the structure to identify the damaged portion of the structure, and inputs and records the location of the damaged portion and its state of damage into the damage information recording unit 200. The method for inputting and recording the location of the damaged portion and its state of damage into the damage information recording unit 200 is not particularly limited, and any method can be adopted. For example, a panoramic photograph of the structure may be taken at the inspection site, and then an inspector at a location separate from the inspection site may visually view the panoramic image displayed on a display, identify the location of the damaged portion on the display, and further input the state of damage (for example, the type of damage, the degree of deterioration, or any other information).

[0019] Next, the operation of the damaged area display unit 300 will be described with reference to Fig. 2. Although Figs. 2 to 4 show plan views of the structure 800, the present invention is not limited to this, and a drawing showing the structure 800 from any direction, such as a side view of the structure 800, can be used. Furthermore, the structure 800 has a lattice-like structure made up of columns 810 and beams 820, 830, 840, 850, etc., that connect the columns 810, but the present invention is not limited to this, and the structure may be any structure.

[0020] As shown in Fig. 2, a blank drawing of a structure 800 to be inspected is displayed on a display unit 100 such as a display. In order to explain the damage representation method of the present invention in comparison with conventional representation methods (Figs. 3 and 4), the location of the damaged area and the state of damage (for example, the type of damage and the degree of deterioration) of this structure 800 are assumed to be the same as those shown in Figs. 3 and 4.

[0021] Specifically, the location of the damaged area and the state of damage will be described. As shown in FIG. 3, beam 820 has damage caused by a single crack. As shown in FIG. 4, the degree of deterioration of beam 820 due to the crack is judged to be "low," and beam 820 is shown in "light gray." Also, as shown in FIG. 3, beam 830 has damage caused by spalling over a wide area. As shown in FIG. 4, the degree of deterioration of beam 830 due to spalling is judged to be "high," and beam 830 is shown in "black." Also, as shown in FIG. 3, beam 840 has damage caused by cracks and spalling. As shown in FIG. 4, the degree of deterioration of beam 840 due to cracks and spalling is judged to be "medium," and beam 840 is shown in "gray."

[0022] In the present invention, the location of the damaged area and the state of damage (e.g., the type of damage and the degree of deterioration) are the same as those shown in Figures 3 and 4, as described above, but are shown in a different manner as shown in Figure 2, as follows:

[0023] Specifically, in the stage of creating a damage representation diagram of the present invention, first, an inspector checks the structure 800 using a photograph or the like, determines the location of a crack in the beam 820, and determines that the damage state is "crack" with a "low" deterioration level, and inputs this information into the damage information recording unit 200. The damaged portion display unit 300 then acquires the data on the location of the damaged portion (the location of the crack) and the damage state ("crack" with a "low" deterioration level) that have been input and recorded in the damage information recording unit 200. Next, the damaged portion display unit 300 generates a damaged portion indicator 710 on the display unit 100, connecting the location of the damaged portion with the reference point P1, and displays this on the display unit 100. Furthermore, in response to the acquired data on the damage state ("crack" with a "low" deterioration level), the damaged portion display unit 300 changes the color of the damaged portion indicator 710 to "light gray," which corresponds to a "low" deterioration level.

[0024] Reference point P1 is located at a position opposite beam 820 of structure 800, and is the starting point of damaged area indicator 710. Reference point P1 is the point where the inspector's viewpoint is located when the inspector looks at the actual structure, identifies the damaged area of ​​the structure, and inputs and records the position of the damaged area and its state of damage into damage information recording unit 200. Alternatively, reference point P1 is the shooting position of equipment shooting the structure when the inspector looks at an image (such as a panoramic image) of the structure, identifies the damaged area of ​​the structure, and inputs and records the position of the damaged area and its state of damage into damage information recording unit 200.

[0025] Furthermore, if it is desired to simultaneously indicate the type of damage (crack), the damaged area indicator 710 may be displayed in a color corresponding to the crack (for example, blue), and further, the density of the blue of the damaged area indicator 710 may be reduced to indicate a "light blue" corresponding to a "low" deterioration level. Furthermore, since the position of the damaged area of ​​the beam 820 is limited to one location within a narrow range, the damaged area indicator 710 is represented in the shape of an arrow, with its tip 711 configured to point to the position of the damaged area.

[0026] As shown in FIG. 2, the damage representation diagram of the present invention created by the above-described method is, for example, checked by an inspector or manager at the next inspection of structure 800 and used to understand the previous damage state of structure 800. When an inspector or manager checks the damage area indicator 710 in the damage representation diagram of FIG. 2, they can easily determine that damage with a "low" deterioration level exists in beam 820 of structure 800 at the location indicated by tip 711 of damage area indicator 710. In contrast, the conventional deformation diagram shown in FIG. 3 requires an inspector to copy the location and extent of cracks in beam 820 from sketches or photographs taken at the inspection site in order to reproduce them as accurately as possible, which is time-consuming and labor-intensive. Furthermore, the conventional judgment diagram shown in FIG. 4 allows the overall deterioration of beam 820 to be evaluated, but does not allow the inspector to determine which parts of beam 820 are damaged. However, in the damage representation diagram of the present application, as shown in Figure 2, by using a damage area indicator 710, it is possible to simply show that there is damage in one location on a beam 820 of a structure 800, and furthermore, information about the damage (the degree of deterioration of the beam 820, the type and extent of the damage, and other arbitrary information) can be grasped by the appearance of the damage area indicator 710 (color, density, shape, and other arbitrary elements).

[0027] Next, other damaged areas will be described in detail. In the stage of creating the damage representation diagram of the present invention, the inspector checks the structure 800 using photographs or the like, determines the location of the spalling on the beam 830, and determines that the damage state is "spadding" and the deterioration level is "high," and inputs this information into the damage information recording unit 200. The damaged area display unit 300 then acquires the data on the location of the damaged area (location of the spalling) and the damage state ("spalling" and the deterioration level is "high") recorded in the damage information recording unit 200. Next, the damaged area display unit 300 generates a damaged area indicator 720 on the display unit 100, connecting the location of the damaged area with the reference point P1, and displays this on the display unit 100. Furthermore, because the location of the damaged area due to the peeling of the beam 830 is wide, the damaged area indicator 720 is represented by a fan shape, with its tip 721 pointing to the range of the damaged area. Furthermore, the damaged area display unit 300 displays the damaged area indicator 720 in black, which corresponds to the high level of deterioration, in response to the acquired data on the damaged state ("peeling" and "high" level of deterioration).

[0028] When an inspector or manager checks the damage representation diagram (Figure 2) of the present invention created by the above-mentioned method at the next inspection of structure 800, the inspector or manager can easily determine that there is damage of a "high" deterioration level at the position indicated by tip 721 of damage area indicator 720 on beam 820 of structure 800.

[0029] If it is desired to simultaneously indicate the type of damage (peeling), the damaged area indicator 720 may be displayed in a color corresponding to the peeling (for example, red), and the intensity of the red in the damaged area indicator 720 may be increased to indicate a "dark red" corresponding to a "high" level of deterioration. In this way, when an inspector looks at the damaged area indicator 720 in Fig. 2, he or she can easily determine that damage of a "high" level of deterioration due to peeling exists in the range indicated by the tip 721 of the damaged area indicator 720 in the beam 830 of the structure 800.

[0030] Next, other damaged areas will be described in detail. In the stage of creating a damage representation diagram of the present invention, an inspector checks structure 800 using photographs or the like, determines the location of spalling on beam 840, and determines that the damage state is "spacking" with a "medium" degree of deterioration, and inputs this information into damage information recording unit 200. Damage area display unit 300 then acquires data on the location of the damaged area (location of spalling) and the damage state ("spacking" with a "medium" degree of deterioration) recorded in damage information recording unit 200. Next, damage area display unit 300 generates a damaged area indicator 730 on display unit 100, connecting the location of the damaged area with reference point P1, and displays the generated data on display unit 100. Furthermore, in response to the acquired data on the damage state ("spacking" with a "medium" degree of deterioration), damage area display unit 300 displays damage area indicator 730 in "gray," which corresponds to a "medium" degree of deterioration. Furthermore, since the location of the peeled portion of beam 840 is limited to one small area, damaged portion indicator 730 is expressed in the shape of an arrow, with tip 731 pointing to the location of the damaged portion.

[0031] If it is desired to simultaneously indicate the type of damage (peeling), the damaged area indicator 730 may be displayed in a color corresponding to the peeling (for example, red), and further, the intensity of the red of the damaged area indicator 730 may be set to a medium level to correspond to a "medium" level of deterioration, so that the damaged area indicator 730 is displayed in "red."

[0032] Similarly, the inspector checks the structure 800 using a photograph or the like, determines the position of a crack in a beam 840 (on one side 841 of the beam 840) and determines that the damage state is "crack" with a "low" degree of deterioration, and inputs this information into the damage information recording unit 200. The damaged portion display unit 300 then acquires the data on the position of the damaged portion (position of the crack) and the damage state ("crack" with a "low" degree of deterioration) recorded in the damage information recording unit 200. Next, the damaged portion display unit 300 generates a damaged portion indicator 740 on the display unit 100 that connects the position of the damaged portion with the reference point P1, and displays this on the display unit 100. Furthermore, in response to the acquired data on the damage state ("crack" with a "low" degree of deterioration), the damaged portion display unit 300 displays the damaged portion indicator 740 in "light gray," which corresponds to a "low" degree of deterioration. In addition, because the position of the cracked portion of beam 840 is limited to one location within a narrow range, damaged portion indicator 740 is expressed in the shape of an arrow, with tip 741 pointing to the location of the damaged portion. This allows an inspector, when looking at damaged portion indicator 740 in Fig. 2, to easily determine that damage with a deterioration level of "low" exists in beam 840 of structure 800 at the location indicated by tip 741 of damaged portion indicator 740.

[0033] If it is desired to simultaneously indicate the type of damage (crack), the damaged area indicator 740 may be displayed in a color corresponding to the crack (e.g., blue), and further, in correspondence with a "low" deterioration level, the intensity of the blue of the damaged area indicator 740 may be reduced, and the damaged area indicator 730 may be displayed in "light blue."

[0034] When an inspector or manager checks the damage representation diagram (FIG. 2) of the present invention created by the above-described method at the next inspection of structure 800, the inspector or manager can easily determine, based on the damage area indicator 730 and the damage area indicator 740 in FIG. 2, that two locations of damage with "medium" and "low" levels of deterioration exist in beam 840 of structure 800, at the positions indicated by tip 731 of damage area indicator 730 and tip 741 of damage area indicator 740. In contrast, the conventional deformation diagram shown in FIG. 3 requires an inspector to copy the location and extent of the spalling and cracks in beam 840 from sketches or photographs taken at the inspection site in order to reproduce them as accurately as possible, which is time-consuming and labor-intensive. Furthermore, the conventional judgment diagram shown in FIG. 4 adjusts the overall deterioration of beam 840 to the worst level of deterioration, making it impossible to determine which parts of beam 840 have multiple damages with different levels of deterioration. However, in the damage representation diagram of the present application, as shown in Figure 2, it is possible to show in a simple manner that there are two damages of different degrees of deterioration in beam 840 of structure 800, and furthermore, information about the damage (degree of deterioration, type and extent of damage) can be grasped from the appearance (color, density, shape) of damaged area indicator 730 and damaged area indicator 740.

[0035] Further, other damaged areas will be described in further detail. In the stage of creating a damage representation diagram of the present invention, the inspector checks the structure 800 using a photograph or the like, determines the location of another crack in the beam 840 (on the other side 842 of the beam 840 opposite one side 841 of the beam 840), and determines that the damage state is "crack" with a "medium" deterioration level, and inputs this information into the damage information recording unit 200. The damaged area display unit 300 then acquires the data on the location of the damaged area (location of the crack) and the damage state ("crack" with a "medium" deterioration level) recorded in the damage information recording unit 200. Next, the damaged area display unit 300 generates a damaged area indicator 750 on the display unit 100, connecting the location of the damaged area with the reference point P2, and displays this on the display unit 100. Furthermore, in accordance with the acquired data on the damage state ("crack" with a "medium" deterioration level), the damaged area indicator 750 is displayed in "gray," which corresponds to a "medium" deterioration level. Furthermore, since the position of the cracked portion of beam 850 is limited to one small area, damaged portion indicator 750 is expressed in the shape of an arrow, with tip 751 pointing to the position of the damaged portion.

[0036] If it is desired to simultaneously indicate the type of damage (crack), the damaged area indicator 750 may be displayed in a color corresponding to the crack (e.g., blue), and the intensity of the blue of the damaged area indicator 750 may be set to a medium level to indicate a "medium" deterioration level, thereby indicating the damaged area indicator 750 in "blue." The reference point P2 is located at a position facing the beam 840 of the structure 800, and is the starting point of the damaged area indicator 750. The second reference point P2, like the first reference point P1, is the position from which the inspector's viewpoint is located or the shooting position of equipment that photographs the structure, but is located on the opposite side of the beam 840 from the reference point P1. The first reference point P1 and the second reference point P2 may be set at any position and in any number.

[0037] When an inspector or manager checks the damage representation diagram ( FIG. 2 ) of the present invention created by the above-described method at the next inspection of the structure 800, the inspector or manager can determine that the first damage area indicator 740 and the second damage area indicator 750 show the beam 840 of the structure 800 from both sides of the beam 840, indicating that the beam 840 is damaged from both sides. By correlating the damage on both sides, the inspector can make a sophisticated judgment (e.g., a crack is progressing from both sides and penetrating the beam 840, suggesting that the beam 840 is severely deteriorated). On the other hand, the conventional deformation diagram shown in FIG. 3 requires an inspector to copy sketches or photographs taken at the inspection site in order to accurately reproduce the extent to which the cracks in the beam 840 have progressed from both sides, which is time-consuming and laborious. Furthermore, the conventional judgment diagram shown in FIG. 4 allows the inspector to evaluate the overall deterioration of the beam 840, but does not indicate whether there is damage on both sides of the beam 840. However, the damage representation diagram of the present application, as shown in Figure 2, can simply show that there is damage on both sides of the beam 840 of the structure 800, and furthermore, enables advanced judgment that correlates the damage on both sides.

[0038] The damage representation diagram of the present invention is displayed on the display surface of a display unit 100 such as a display, as shown in FIG. 2 . However, this is not limited to this. The damage representation diagram may be displayed on a display surface such as paper or any other display medium. The damage area indicator of the present invention is shaped like an arrow or a fan, but is not limited to this and may be changed to any shape corresponding to the damage state. The color and density of the damage area indicator of the present invention are changed according to the type of damage and the degree of deterioration, but are not limited to this and can be changed in accordance with any information related to the damage. The damage area indicator of the present invention is changed in color, density, and shape, but is not limited to this. Other changes, such as brightness of the damage area indicator, may also be made. The damage representation system and damage representation diagram of the present invention are not limited to the above examples. Various modifications and combinations are possible within the scope of the claims and embodiments, and these modifications and combinations are also included within the scope of the claims.
