JP7725764B2 - Damage level display device, damage level specific display system, and program - Google Patents

Description

The present invention relates to a damage level display device, a damage level identification display system, and a program.

In conventional systems that assess and display the degree of damage to buildings during earthquakes, for example, the degree of damage is assessed and displayed for each floor, making it impossible to specifically identify the damaged areas on each floor, and the displayed damage level information is vague and difficult to understand.

Specifically, even if the degree of damage to the entire floor of a building is displayed, the degree of damage to the building frame, equipment, and finishing materials such as exterior wall panels on each floor may vary, so unless the degree of damage to specific parts on each floor is displayed individually, it is not possible to clearly determine the degree of damage.

On the other hand, if the damage level of specific parts on each floor were to be displayed individually, a large number of display contents would be required, making it extremely difficult to clearly display the specific damage level of each part on a single screen, such as on a smartphone, tablet, or personal computer. In a multi-story building, if the damage level of specific parts on each floor were to be displayed individually on a single screen, the number of display contents would be even greater, making it even more difficult to display in an easy-to-understand manner. For example, one method could be to display the damage level on a different screen for each floor, but if the damage level of each floor were to be displayed on a different screen, it would be difficult to understand the degree of damage on each floor in the context of the entire building (it would be impossible to compare which floors were more damaged with other floors, for example). Therefore, it is desirable to display the damage level of specific parts on each floor individually on a single computer screen.

For these reasons, there is a demand for a damage level display device or damage level identification display system that can clearly display the damage level of specific parts on each floor of a multi-story building on a single computer screen.

Patent Document 1 proposes a damage level display system. This damage level display system includes multiple measurement means attached to multiple buildings, each measuring the magnitude of shaking that occurs in the buildings; damage level determination means for determining the degree of damage, or the level of damage, of each of the multiple buildings based on the measured magnitude of shaking; earthquake determination means for determining whether an earthquake has occurred based on the measured magnitude of shaking; recording means for recording the determined damage level when it is determined that an earthquake has occurred; display control means for displaying the damage level recorded by the recording means on a display terminal having a display unit; and viewing authority determination means for determining the viewing authority held by the user of the display terminal. The display control means also includes information restriction means for restricting the display of the damage level of a specific building from the multiple recorded damage levels on the display unit based on the determined viewing authority.

Japanese Patent Application Laid-Open No. 2020-176866

The damage level display system described in Patent Document 1 is said to be able to appropriately notify users of the damage level of a building, but because this system notifies users of the damage level of the entire building, as mentioned above, it is not able to clearly display the damage level of specific parts on each floor of a multi-story building on a single screen.

The present invention was made in consideration of the above-mentioned problems, and aims to provide a damage level display device, a damage level identification display system, and a program that can clearly display the damage level of specific parts on each floor of a multi-story building on a single computer screen.

In order to achieve the above object, one aspect of the damage level display device according to the present invention is:
A damage level display device that displays the damage level of a multi-story building during an earthquake,
It has a display unit,
In the display unit,
The floors and ceilings of each floor are represented by geometric models, and the walls and pillars connecting the floors and ceilings are represented by line models. The geometric models and line models of each floor are connected vertically to display a skewer model.
The skewer model is characterized in that the geometric model and the line model are color-coded according to the degree of damage to parts of each floor.

In this embodiment, the display unit of the damage level display device represents the floors and ceilings of each floor as geometric models, and the walls and columns connecting the floors and ceilings as line models. The geometric and line models of each floor are displayed as a connected model connected vertically, and the geometric and line models are color-coded according to the damage level of each part on each floor. This makes it easy to understand the damage level of each part of the building structure, such as walls and columns, floors, ceilings, and equipment, by color-coding the geometric and line models specific to each part. Furthermore, because all floors are displayed as a single connected model, the damage level of buildings of various heights, from low-rise buildings of around two or three stories to high-rise and super-high-rise buildings of around several dozen stories, can be displayed on a single screen.

Here, geometric models include various shape models such as circles (○), triangles (△), squares (□), diamonds (◇), and stars (☆), and for example, a circle (○) can be selected to form a skewer model.

In addition, color coding according to the level of damage involves coloring dangerous conditions in red, conditions requiring inspection in yellow, and safe conditions in green, and by looking at the colors of the line model and geometric model, the safety and risk levels of each part on each floor can be easily understood in a short amount of time.

Furthermore, for example, by creating a unique interlocking model for each building's frame and equipment, and displaying all interlocking models on a single computer screen, it becomes possible to quickly understand the damage level information for various parts on each floor.

Another aspect of the damage level display device according to the present invention is
The model type of the geometric model and the line type of the line model are both different depending on the degree of damage to the parts of each floor.

In this embodiment, both the model type of the geometric model and the line type of the line model differ depending on the degree of damage to parts of each floor. Therefore, even if, for example, the display screen is printed out in black and white and it is difficult to adequately determine the degree of damage to each part of each floor based on color coding alone, it is possible to clearly identify the degree of damage based on the model type of the geometric model and the line type of the line model.

For example, as mentioned above, model types for geometric models include circles (○), triangles (△), squares (□), etc., with examples showing dangerous states as triangles (△), states requiring inspection as squares (□), and safe states as circles (○). Line types for line models include solid, dotted, and dashed-dotted lines, as well as varying the thickness of the lines, with examples showing dangerous states as dotted lines, states requiring inspection as thin solid lines, and safe states as thick solid lines.

In another aspect of the damage level display device according to the present invention,
The damage level includes at least one of the damage level of the building frame, the damage level of the equipment, the damage level of the ceiling, and the damage level of the exterior wall panels.

According to this aspect, the damage level includes at least one of the following: damage level to the building structure, damage level to equipment, damage level to the ceiling, and damage level to the exterior wall panels, making it possible to identify the necessary and sufficient damage level for each part on each floor.

Here, the "structure" is made up of the columns and walls of each floor, with the floors and ceilings of each floor displayed as geometric models and the columns and walls displayed as line models. Furthermore, equipment mainly includes, for example, equipment piping, with equipment piping under the floor displayed as geometric models and equipment piping inside and outside the columns and walls displayed as line models. In other words, equipment such as equipment piping located in positions corresponding to the floors and ceilings is displayed as a geometric model, and equipment such as equipment piping located in positions corresponding to the columns and walls is displayed as a line model.

In addition to the ceiling components, the ceiling also includes the lighting fixtures installed on the ceiling. Even if the ceiling components are safe, if the lighting fixtures have fallen or are about to fall, they will be displayed as needing inspection or in a dangerous state.

Furthermore, if the exterior wall panels have cracks in the exterior wall surface materials (finishing materials) such as various siding materials, or if some of the exterior wall surface materials have fallen off, they will be displayed as requiring inspection or in a dangerous state.

In another aspect of the damage level display device according to the present invention,
The damage level display device further includes an identification unit that identifies the damage level of each floor during an earthquake,
In the identification unit,
Identifying the maximum acceleration of each floor based on measurement data measured by seismometers installed on all or any floors, and identifying the story deformation angle of each floor based on the maximum acceleration of each floor;
The display unit creates and displays the skewer model according to the degree of damage based on at least one of the maximum acceleration and the inter-story deformation angle of each floor identified by the identification unit.

In this aspect, the damage level display device further includes an identification unit that identifies the damage level of each floor during an earthquake. This identifies the maximum acceleration of each floor based on measurement data measured by, for example, multiple seismometers installed in the building, and identifies the inter-story deformation angle of each floor based on the maximum acceleration of each floor. Based on these identified values, a connected model corresponding to the damage level is created and displayed on the display unit, making it possible for a single computer to continuously perform processes from calculating the displacement and inter-story deformation angle of each floor to displaying the damage level.

Here, seismometers may be installed on all floors of a multi-story building, or on any floor (for example, the first, third, and fifth floors in a five-story building). For example, when using measurement data from a seismometer on any floor to determine the maximum acceleration on all floors, as in the latter case, the maximum acceleration on all floors can be determined by interpolating the maximum acceleration on intermediate floors from the maximum acceleration on floors above and below, or by extrapolating the maximum acceleration on a floor above from the maximum acceleration on a lower floor, for example.

Displacement data is calculated by integrating acceleration data measured by seismometers twice. The inter-story deformation angle between upper and lower floors is calculated based on the maximum displacement data for each floor and the floor height. Therefore, "determine the inter-story deformation angle for each floor based on the maximum acceleration for each floor" includes "determine the maximum displacement for each floor based on the maximum acceleration for each floor, and determine the inter-story deformation angle based on the maximum displacement for each floor." In this regard, "based on at least one of the maximum acceleration and inter-story deformation angle for each floor" includes "based on at least one of the maximum acceleration, maximum displacement, and inter-story deformation angle for each floor."

Measurement data may be transmitted from the seismometer to the damage level display device via communication, or an administrator or other person may obtain measurement data from the seismometer and input the obtained measurement data into the damage level display device.

Furthermore, one aspect of the damage level identification display system according to the present invention is
a damage level determination device that determines the damage level of each floor of a multi-story building during an earthquake;
a damage level display device that displays the damage level of each floor based on the identification result by the damage level identification device,
In the damage level display device,
The floors and ceilings of each floor are represented by geometric models, and the walls and pillars connecting the floors and ceilings are represented by line models. The geometric models and line models of each floor are connected vertically to display a skewer model.
The skewer model is characterized in that the geometric model and the line model are color-coded according to the degree of damage to parts of each floor.

According to this aspect, by having a damage level determination device that determines the damage level of each floor and a damage level display device that displays the damage level of each floor based on the results of the determination by the damage level determination device, various damage level display devices can share a common display screen showing the damage level of each part of each floor of a building, using the results determined by the damage level determination device.

Here, the damage level determination device may be installed, for example, at the head office or branch of the construction company that built the building, or at the building management company, or it may be a server device on the cloud. The damage level display device may also be a smartphone, tablet, personal computer, etc. owned by the head office or branch of the construction company that built the building, the building management company, or a resident of the building. For example, a building management company can identify floors in the building that require urgent repairs or reinforcement based on the content displayed on its own damage level display device and quickly proceed to repair work, etc., and resident users can quickly determine whether they can continue occupying the building and whether urgent repairs, etc. are required based on the content displayed on their own damage level display device.

In another aspect of the damage level identification display system according to the present invention,
The model type of the geometric model and the line type of the line model are both different depending on the degree of damage to the parts of each floor.

According to this aspect, for example, when the display screen is printed out in black and white, even if it is difficult to adequately determine the degree of damage to each part of each floor using color coding alone, it is possible to clearly identify the degree of damage using the model type of the geometric model and the line type of the line model.

In another aspect of the damage level identification display system according to the present invention,
In the damage level determination device,
Identifying the maximum acceleration of each floor based on measurement data measured by seismometers installed on all or any floors, and identifying the story deformation angle of each floor based on the maximum acceleration of each floor;
The damage level display device creates and displays the skewer model according to the level of damage based on at least one of the maximum acceleration and the inter-story deformation angle of each floor identified by the damage level identification device.

According to this aspect, the damage level determination device determines the maximum acceleration for each floor based on measurement data measured by, for example, multiple seismometers installed in the building, and determines the inter-story deformation angle for each floor based on the maximum acceleration for each floor. By transmitting the determination results (specific data) to, for example, multiple damage level display devices, it becomes possible to share common display content among multiple damage level display devices located in remote locations based on the specific data determined by the damage level determination device.

Furthermore, one aspect of the program according to the present invention is
A program that causes a computer constituting a damage level display device to execute the following processes to display the damage level of a multi-story building during an earthquake:
The floors and ceilings of each floor are represented by geometric models, and the walls and pillars connecting the floors and ceilings are represented by line models. The geometric models and line models of each floor are connected vertically to display a skewer model.
The skewer model is characterized in that the geometric model and the line model are color-coded according to the degree of damage to parts of each floor.

In this aspect, the computer constituting the damage level display device executes a process to create a connected model in which geometric models and line models are color-coded according to the damage level of parts on each floor, making it possible to clearly display the damage level of specific parts on each floor on a single computer screen.

Another aspect of the program according to the present invention is
A program that causes a computer constituting a damage level display device to execute the following processes to identify and display the damage level of a multi-story building during an earthquake:
Identifying the maximum acceleration of each floor based on measurement data measured by seismometers installed on all or any floors, and identifying the story deformation angle of each floor based on the maximum acceleration of each floor;
Based on at least one of the identified maximum acceleration of each floor and the inter-story deformation angle, the floors and ceilings of each floor are represented by geometric models, and the walls and columns connecting the floors and ceilings are represented by line models. The geometric models and line models of each floor are connected vertically and displayed as a skewer model, and in the skewer model, the geometric models and line models are color-coded according to the degree of damage to the parts of each floor.

In this manner, a single damage level display device identifies the maximum acceleration for each floor, identifies the inter-story deformation angle for each floor based on the maximum acceleration for each floor, and creates and displays a connected model according to the damage level based on these identified values, making it possible for a single computer to continuously perform processes from calculating the displacement and inter-story deformation angle for each floor to displaying the damage level.

As can be understood from the above explanation, the damage level display device, damage level identification display system, and program of the present invention can clearly display the damage level of specific parts on each floor of a multi-story building on a single computer screen.

An example of a damage level identification display system, a damage level display device, and a program according to an embodiment will be described below with reference to the accompanying drawings. Note that in this specification and drawings, substantially identical components may be designated by the same reference numerals to avoid redundant description.

[Disaster level identification display system according to the embodiment and disaster level display device according to the first embodiment]
First, a damage level identification display system according to an embodiment and an example of a damage level display device according to the first embodiment will be described with reference to Figures 1 to 6. Here, Figure 1 is a diagram showing the overall configuration of an example of a damage level identification display system according to an embodiment.

The damage level identification display system 100 comprises a multi-story building 10 that is subject to damage level management in the event of an earthquake, a damage level identification device 40 located at a management company 30 that manages the building 10, and multiple damage level display devices 50 that display the damage level of each part of each floor of the building 10 based on specific data identified by the damage level identification device 40. Here, the damage level identification device 40 may be installed in a management room in the building 10, or in a management department such as the head office or branch office of the construction company that built the building 10, or it may be a server device on the cloud.

The building 10 in the illustrated example is a seven-story building, with seismometers 15A, 15B, 15C, and 15D installed on the first, third, fifth, and rooftop floors (RF), respectively. The building 10 vibrates due to seismic motion E propagating through the ground G, and the measurement data (acceleration data, for example, acceleration data on the X-, Y-, and Z-axes) measured by the seismometers 15 on each floor is transmitted to the damage level determination device 40 via the network 20. It is also possible for seismometers 15 to be installed on all floors of the building 10.

The damage level identification device 40 calculates and identifies the maximum acceleration of each floor of the building 10 based on the received measurement data, calculates the maximum displacement of each floor by integrating the maximum acceleration of each floor twice, and calculates the inter-story deformation angle of each floor based on the maximum displacement of each floor and the floor height, and these become the identification data.

The specific data calculated by the damage level determination device 40 is transmitted to multiple damage level display devices 50 via the network 20. In some cases, the data calculated by the damage level determination device 40 and displayed on the damage level display device 50 is also transmitted (notified) to multiple related departments via email. Here, the damage level display device 50 is the damage level display device according to the first embodiment, and is a device that displays information related to the damage level on one computer screen based on the received specific data (in other words, the damage level determination device 40 does not calculate the specific data).

The multiple damage level display devices 50 are, for example, smartphones 50A and tablets 50B carried by residents of the building 10, personal computers 50C, or computers at the management company 30 or a construction company (not shown), etc.

Network 20 includes public networks such as the Internet, wireless networks such as mobile phone networks, dedicated networks such as VPNs (Virtual Private Networks), LANs (Local Area Networks), etc.

In this way, the damage level identification display system 100 is a system in which each seismometer 15, damage level identification device 40, and damage level display device 50 are connected via a network 20. However, for example, the system may be configured so that an administrator or the like obtains measurement data measured by each seismometer 15 and inputs the data into the damage level identification device 40, or the specific data calculated by the damage level identification device 40 is input into all or some of the damage level display devices 50.

Next, referring to Figure 2, an example of the hardware configuration of the damage level determination device 40 and the damage level display device 50 according to the first embodiment will be described, and referring to Figures 3 and 4, an example of the functional configuration of the damage level determination device 40 and the damage level display device 50 will be described.

As shown in Figure 2, both the damage level identification device 40 and the damage level display device 50 are configured as information processing devices (computers) such as personal computers (PCs).

The computer that constitutes the damage level identification device 40 and the damage level display device 50 includes a CPU (Central Processing Unit) 41, a main memory device 42, an auxiliary memory device 43, an input/output IF (interface) 44, and a communication IF 45, all of which are interconnected via a connection bus 46. The main memory device 42 and the auxiliary memory device 43 are computer-readable recording media. Note that the above components may be provided separately, or some components may not be provided.

The CPU 41 is also called an MPU (Microprocessor) or processor, and may be a single processor or multiple processors. The CPU 41 is a central processing unit that controls the entire damage level determination device 40 and damage level display device 50, which are computers. The CPU 41, for example, deploys programs stored in the auxiliary storage device 43 in an executable form in the working area of the main storage device 42, and controls peripheral devices through the execution of the programs, thereby providing functions that meet specific purposes.

The main memory device 42 stores computer programs executed by the CPU 41, data processed by the CPU 41, etc. The main memory device 42 includes, for example, flash memory, RAM (Random Access Memory), and ROM (Read Only Memory). The auxiliary memory device 43 stores various programs and data on a readable and writable recording medium, and is also referred to as an external memory device. The auxiliary memory device 43 stores, for example, an OS (Operating System), various programs, various tables, etc. The OS includes, for example, a communication interface program that exchanges data with external devices connected via the communication IF 45. External devices for the damage level determination device 40 include the seismometer 15 and the damage level display device 50, and external devices for the damage level display device 50 include the damage level determination device 40, etc.

The auxiliary storage device 43 is used, for example, as a storage area that supports the main storage device 42, and stores computer programs executed by the CPU 41, data processed by the CPU 41, etc. The auxiliary storage device 43 may be a silicon disk including non-volatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD), a solid state drive, etc. Examples of the auxiliary storage device 43 include drives for removable recording media such as CD drives, DVD drives, and BD drives, and examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memory, and SD (Secure Digital) memory cards.

The input/output IF 44 is an interface that inputs and outputs data between the damage level determination device 40 and devices connected to the damage level display device 50. Input devices such as a keyboard, a touch panel, a mouse or other pointing device, and a microphone are connected to the input/output IF 44. Both the damage level determination device 40 and the damage level display device 50 accept operational instructions from an operator operating an input device via the input/output IF 44.

In addition, the input/output IF 44 is connected to display devices such as liquid crystal panels (LCD: Liquid Crystal Display) and organic electroluminescence (EL) panels, as well as output devices such as printers and speakers. The damage level identification device 40 displays, for example, the maximum acceleration, maximum displacement, and inter-story deformation angle of each floor of the building, and the damage level display device 50 displays, on a single screen, the floors and ceilings of each floor as geometric models, the walls and columns connecting the floors and ceilings as line models, and a skewer model in which the geometric models and line models of each floor are connected vertically. An example of this display screen is described in detail below.

The communication IF 45 is an interface between the damage level determination device 40 and the network 20 to which the damage level display device 50 is connected. The communication IF 45 transmits specific data from the damage level determination device 40 to the damage level display device 50 via various networks 20, including the above-mentioned public networks such as the Internet, and the damage level display device 50 receives the specific data from the damage level determination device 40.

As shown in FIG. 3, the damage level identification device 40 provides various functions of at least the communication unit 402, identification unit 404, and storage unit 406 through program execution by the CPU 41. Also, as shown in FIG. 4, the damage level display device 50 provides various functions of at least the communication unit 502, display unit 504, and storage unit 506 through program execution by the CPU 41. Here, at least some of the above processing functions may be provided by a DSP (Digital Signal Processor), GPU (Graphics Processing Unit), etc. Similarly, at least some of the above processing functions may be provided by dedicated LSIs (large scale integration) such as FPGAs (Field-Programmable Gate Arrays), numerical calculation processors, image processing processors, or other digital circuits.

First, we will explain an example of the functional configuration of the damage level determination device 40.

After an earthquake occurs, the communication unit 402 receives measurement data transmitted from each seismometer 15 for a certain period of time and stores the data in the storage unit 406 as needed.

The identification unit 404 identifies or calculates the maximum acceleration for each floor based on the measurement data. In the illustrated example, the building 10 has seismometers 15 installed on any floor, such as the first or third floor. Therefore, the maximum acceleration on the floor on which the seismometer 15 is installed is identified based on the time history waveform of the acceleration measured by each seismometer 15, and the maximum acceleration on floors on which a seismometer 15 is not installed is calculated by interpolating or extrapolating the maximum acceleration of other identified floors. In this way, the identification unit 404 separately identifies and calculates the maximum acceleration on floors on which a seismometer 15 is installed and on floors on which a seismometer 15 is not installed.

The identification unit 404 calculates the maximum displacement of each floor by integrating twice the identified or calculated maximum acceleration of each floor. Furthermore, it calculates the inter-story deformation angle of each floor based on the maximum displacement and floor height of each floor.

Next, we will explain an example of the functional configuration of the damage level display device 50.

The communication unit 502 receives specific data (maximum acceleration on each floor, maximum displacement on each floor, inter-story deformation angle on each floor, etc.) transmitted from the damage level identification device 40 and stores it in the storage unit 508.

The display unit 504 displays the damage level of specific parts on each floor of the building 10 (all seven floors in the illustrated example) individually on a single computer screen.

Here, with reference to Figures 5 and 6, we will explain an example of how the damage level is displayed on the display unit 504.

The display example shown in Figure 5 shows, in the left area of one screen, the maximum acceleration distribution and maximum displacement distribution (corresponding to the inter-story deformation angle) for each floor, which are the basis for determining the degree of damage, as well as the seismic intensity for the first, third, fifth, and rooftop floors, where seismometers 15 are installed.

On the other hand, the right side of the screen displays the interlocking models M1, M2, M3, and M4 for the building frame, equipment piping, ceiling (including lighting fixtures), and exterior wall panels.

Each skewer model is formed by representing the floors and ceilings as geometric models with circles (○), and the walls and pillars connecting the floors and ceilings with line models, and connecting the geometric and line models of each floor vertically.

In addition, the geometric model and line model are color-coded according to the level of damage to each part of each floor, with red indicating a dangerous condition, yellow indicating a condition requiring inspection, and green indicating a safe condition.

Here, the damage level of the geometric model is calculated based on the maximum acceleration, and the damage level of the line model is calculated based on both the inter-story deformation angle and the maximum acceleration. Furthermore, the damage level of the exterior wall panels is calculated based on the inter-story deformation angle, and the damage level of the equipment is calculated based on the maximum acceleration.

In this way, because each part of each floor is displayed as a connected model, multiple types of connected models (structure, equipment piping, etc.) can be displayed on a single screen, and by looking at the colors of the line models and geometric models, the safety and risk levels of each part on each floor can be easily understood in a short amount of time. In addition, because all information for each floor can be seen on a single screen, trends in the degree of damage on each floor can be quickly identified, making this display content effective for emergency evacuation measures, emergency reinforcement measures, etc.

The display screen shows an overall assessment at the bottom, and in the example shown, it shows whether the building can continue to be used, as well as areas that require inspection and areas that are dangerous.

In addition to the illustrated example, a single screen may display only the skewer model in the right-hand area shown in Figure 5, or the skewer model in the right-hand area and the overall evaluation in the lower section. In this case, it is recommended that the maximum acceleration distribution for each floor in the left-hand area shown in Figure 5 be displayed on a separate screen.

On the other hand, the display example shown in Figure 6 differs from the display example shown in Figure 5 in that both the model type of the geometric model and the line type of the line model differ depending on the degree of damage to each floor, and displays interlocking models M5, M6, M7, and M8 for the building frame, equipment piping, ceiling (including lighting fixtures), and exterior wall panels.

The geometric model indicating a dangerous state is a triangle (△) and the line model is a dotted line, the geometric model indicating a state requiring inspection is a square (□) and the line model is a thin solid line, and the geometric model indicating a safe state is a circle (○) and the line model is a thick solid line. As in Figure 5, the coloring is red for a dangerous state, yellow for a state requiring inspection, and green for a safe state.

In this way, by using different model types for both the geometric model and the line type for the line model depending on the degree of damage to each part of each floor, even when the display screen is printed out in black and white and it is difficult to adequately determine the degree of damage to each part of each floor using color coding alone, it is possible to clearly identify the degree of damage using the model type for the geometric model and the line type for the line model.

The damage level display device 50 displays the above on the display unit 504 by installing a program that causes a computer to execute the following process. That is, the process based on this program represents the floors and ceilings of each floor as geometric models, the walls and columns connecting the floors and ceilings as line models, connects the geometric and line models of each floor vertically to display a skewer model, and colors the geometric and line models in the skewer model according to the damage level of each part of each floor.

[Disaster level display device according to the second embodiment]
Next, a damage level display device according to a second embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing an example of the functional configuration of the damage level display device according to the second embodiment.

The damage level display device 60 is a device that has all the functions of the damage level identification device 40 and damage level display device 50 shown in Figure 1, and a single computer performs a series of processes, from creating specific data by identifying and calculating the maximum acceleration for each floor based on measurement data from the seismometer 15, to identifying and displaying the damage level for each floor based on the specific data.

The communication unit 602 receives measurement data transmitted from each seismometer 15 for a fixed period of time and stores it in the storage unit 608 as needed.

The identification unit 604 identifies or calculates the maximum acceleration for each floor based on the measurement data, and calculates the maximum displacement for each floor by integrating the identified or calculated maximum acceleration for each floor twice. Furthermore, it calculates the inter-story deformation angle for each floor based on the maximum displacement and floor height for each floor.

The display unit 606 displays the damage level of specific parts on each floor of the building 10 individually on a single computer screen.

The damage level display device 60 executes the above-mentioned processes in the identification unit 604 and display unit 606 by installing a program that causes a computer to execute the following processes. Specifically, the process based on this program identifies the maximum acceleration for each floor based on measurement data measured by the seismometer 15, identifies the inter-story deformation angle for each floor based on the maximum acceleration for each floor, represents the floors and ceilings of each floor as geometric models based on at least one of the identified maximum acceleration and inter-story deformation angle for each floor, represents the walls and columns connecting the floors and ceilings as line models, connects the geometric models and line models of each floor vertically to display a skewer model, and color-codes the geometric models and line models in the skewer model according to the damage level of each part of each floor.
