However, despite the aforementioned background technologies, disaster prevention equipment and timelines are not functioning adequately, resulting in situations where facilities are damaged, their functions are impaired, and they are unable to fulfill their role in the affected area. For example, in the case of medical facilities, damage to medical functions can impair their services, leading to serious disruptions to regional healthcare for a specified period.

This invention was made in view of the circumstances described above, and aims to provide a disaster prevention support device and method that can assist in the creation of more practical disaster prevention plans than conventional methods.

To achieve the above objective, the present invention provides a first solution relating to a disaster prevention support device, comprising: a facility information acquisition unit that acquires facility information of a disaster prevention target facility; a disaster prevention information acquisition unit that acquires disaster prevention information; and a support information creation unit that creates a disaster prevention timeline as disaster prevention support information based on the facility information and the disaster prevention information. The support information creation unit performs a risk assessment of the equipment of the disaster prevention target facility by comparing the installation height and floor height of the building and equipment included in the facility information with the flood height predicted based on the disaster prevention information. It also acquires the organizational structure of the disaster prevention target facility, the work content of facility staff in each department during a flood, the person in charge of each task, the working time for each task, and the disaster prevention manual from the facility information as individual work content during a flood. Based on the risk assessment and the individual work content during a flood, it creates a disaster prevention action-related table that shows disaster prevention actions related to floods in chronological order, and creates the disaster prevention timeline based on the disaster prevention action-related table. The means adopted is that the disaster prevention target facility is a medical facility .

In the present invention, as a third solution relating to a disaster prevention support device, the first solution described above employs the means that the facility information includes survey information relating to the buildings or equipment constituting the disaster prevention target facility.

In the present invention, as a fourth solution relating to a disaster prevention support device, in the first solution described above, when floods are the target of disaster prevention, the disaster prevention information is provided to include water level prediction information for rivers located in the target area.

In the present invention, as a fifth solution relating to a disaster prevention support device, the first solution described above adopts the method that the disaster prevention timeline is an action plan showing who will take disaster prevention actions at the disaster-affected facility and at what timing.

The present invention provides a solution for a disaster prevention support method comprising: a facility information acquisition step in which a computer acquires facility information of a disaster-target facility; a disaster prevention information acquisition step in which the computer acquires disaster prevention information; and a support information creation step in which the computer creates a disaster prevention timeline based on the facility information and the disaster prevention information. The support information creation step involves comparing the installation height and floor height of buildings and equipment included in the facility information with the flood height predicted based on the disaster prevention information to perform a risk assessment of the equipment of the disaster-target facility; acquiring the organizational structure of the disaster-target facility, the work content of facility staff in each department during a flood, the person in charge of each task, the working hours for each task, and the disaster prevention manual as individual work content during a flood from the facility information; creating a disaster prevention action-related table that shows disaster prevention actions related to floods in chronological order based on the risk assessment and the individual work content during a flood; and creating the disaster prevention timeline based on the disaster prevention action-related table. The disaster-target facility is a medical facility .

According to the present invention, it is possible to provide a disaster prevention support device and a disaster prevention support method that can assist in the creation of more practical disaster prevention plans than those used in the past.

This is a block diagram showing the functional configuration of disaster prevention support device A according to one embodiment of the present invention. This is a flowchart showing the operation of disaster prevention support device A according to one embodiment of the present invention. This is a schematic diagram showing the disaster prevention timeline in one embodiment of the present invention. This is a schematic diagram showing a table of disaster prevention actions in one embodiment of the present invention. This is a schematic diagram showing the disaster prevention timeline in one embodiment of the present invention.

One embodiment of the present invention will be described below with reference to the drawings.
The disaster prevention support device A according to this embodiment assists in the creation and implementation of disaster prevention plans that target floods among various types of disasters. While there are various types of facilities that can be targeted for disaster prevention (disaster prevention target facilities), the disaster prevention support device A according to this embodiment targets medical facilities that provide regional medical care as an example.

This disaster prevention support device A is, for example, a general-purpose computer equipped with a disaster prevention support program (application program). Disaster prevention support device A creates and updates disaster prevention support information specific to medical facilities by acquiring information necessary for supporting the creation of disaster prevention plans from external server B or facility server C. This disaster prevention support information includes disaster prevention timelines and disaster action-related tables, which are essential for creating and implementing disaster prevention plans in medical facilities.

As will be explained in more detail later, a disaster prevention timeline is a type of disaster support information, and it is an action plan that shows who will take what actions (preventive measures before a disaster occurs) and when. For example, some medical facilities have waterproofing equipment consisting of watertight walls and watertight plates to prepare for floods, and this waterproofing equipment achieves its desired waterproofing function by activating or installing movable watertight plates.

Therefore, in order for the waterproofing function to work effectively, the water barriers must be activated or installed at the appropriate time. However, the activation of the water barriers is carried out based on the judgment of the disaster prevention personnel at the medical facility. The disaster prevention timeline includes a plan outlining when the activation of the water barriers, which is one of the disaster prevention actions, will be performed.

The Disaster Prevention Action Chart is a type of disaster prevention support information, a timeline of disaster prevention actions that medical facilities should take in the pre-flood phase. This chart can be used for disaster prevention drills at medical facilities simulating floods. By conducting disaster prevention drills according to this chart, disaster prevention plans can be refined to be more effective.

To begin with, regarding external server B and facility server C, external server B is a collection of multiple servers that provide disaster prevention information related to medical facilities to disaster prevention support device A. This disaster prevention information includes, for example, hazard maps and past flood information for the area where the medical facility is located (target area), weather information such as rainfall and river water levels in the target area during past floods, and water level forecast information (RRI information) for rivers in the target area from a certain point in time onward.

The RRI information is a water level forecast result that predicts river water levels up to four hours in advance based on a publicly known RRI model, and includes past water level forecast results for multiple rivers in Japan. The RRI model predicts river water levels based on rainfall, runoff, and inundation in a given region.

Facility Server C is a server managed by the medical facility and provides various information (facility information) related to the medical facility to Disaster Prevention Support Device A. Facility information includes at least architectural information such as the location and height of each building and various equipment constituting the medical facility, organizational information regarding various organizations within the medical facility, the job descriptions of members of various organizations (hospital staff), the medical facility's disaster prevention manual for floods, information gathered from interviews with hospital staff, records of past flood responses, and records of past inundation.

Here, the above architectural information includes not only design documents for the medical facility, but also survey information, photographs and videos, maintenance records, and conventional survey information and 3D point cloud survey information for each building and various equipment within the medical facility. In other words, the architectural information includes information from the time of construction of the medical facility, as well as information showing the condition of each building and various equipment at the time of creation of the disaster prevention plan (present).

As shown in Figure 1, disaster prevention support device A is a general-purpose computer comprising at least a communication unit 1, a storage unit 2, an operation unit 3, a calculation unit 4, and a display unit 5. These communication unit 1, storage unit 2, operation unit 3, calculation unit 4, and display unit 5 are hardware elements constituting the general-purpose computer. Disaster prevention support device A creates and updates disaster prevention timelines and disaster prevention action-related tables through the cooperation of these hardware elements and software elements (disaster prevention support programs).

The communication unit 1 is electrically connected to the calculation unit 4 and is also freely connected to the external server B. Based on information acquisition instructions input from the calculation unit 4, the communication unit 1 communicates with the external server B to acquire disaster prevention information, weather information, and water level forecast information. The communication unit 1 outputs the disaster prevention information, weather information, and water level forecast information acquired from the external server B to the calculation unit 4. This communication unit 1 is the facility information acquisition unit and disaster prevention information acquisition unit in this embodiment.

The memory unit 2 is a collection of multiple storage devices, including ROM (Read Only Memory), RAM (Random Access Memory), and a hard disk, and is electrically connected to the arithmetic unit 4. The memory unit 2 pre-stores the aforementioned disaster prevention support program in the ROM and, based on write instructions received from the arithmetic unit 4, stores disaster prevention information, weather information, and water level prediction information, for example, in the hard disk. Furthermore, the memory unit 2 provides disaster prevention information, weather information, and water level prediction information to the arithmetic unit 4 based on read instructions received from the arithmetic unit 4.

The operation unit 3 is a collection of components such as a keyboard and mouse, and is electrically connected to the processing unit 4. The operation unit 3 receives instructions (operational commands) from the operator regarding the creation and updating of disaster prevention timelines and disaster prevention action-related tables, and outputs these instructions to the processing unit 4. These operational commands are processed by the processing unit 4 based on the disaster prevention support program. The operator is a disaster prevention officer (facility staff) of a medical facility involved in the creation and updating of disaster prevention timelines and disaster prevention action-related tables.

The calculation unit 4 is electrically connected to the communication unit 1, the storage unit 2, the operation unit 3, and the display unit 5. The calculation unit 4 creates and updates the disaster prevention timeline and disaster prevention action-related table by reading and executing the disaster prevention support program (application program) from the storage unit 2, and based on operation instructions input from the operation unit 3.

Furthermore, the calculation unit 4 outputs the disaster prevention timeline and disaster prevention action-related table, created based on the disaster prevention support program and operation instructions, to the display unit 5 and stores them in the storage unit 2. The calculation unit 4 also transfers the disaster prevention timeline and disaster prevention action-related table to a predetermined destination based on the operation instructions. This calculation unit 4 is the support information creation unit in this embodiment.

The display unit 5 is, for example, a liquid crystal display device and is electrically connected to the calculation unit 4. The display unit 5 displays the disaster prevention timeline and disaster prevention action-related table, input from the calculation unit 4, as images. Medical facility staff create disaster prevention plans for the facility based on the disaster prevention timeline and disaster prevention action-related table displayed on the display unit 5.

Next, the operation of the disaster prevention support device A according to this embodiment, that is, the disaster prevention support method using the disaster prevention support device A, will be explained in detail with reference to Figures 2 to 5.

The calculation unit 4 of the disaster prevention support device A, upon starting the execution of the disaster prevention support program, first acquires disaster prevention information from the external server B (step S1). That is, the calculation unit 4 outputs a disaster prevention information acquisition instruction to the communication unit 1, causing it to send a request to transmit disaster prevention information to the external server B. The external server B responds to the transmission request and transmits disaster prevention information for the target area to the disaster prevention support device A. The communication unit 1 receives the disaster prevention information from the external server B and outputs it to the calculation unit 4. Step S1 is the disaster prevention information acquisition process in this embodiment.

Next, the calculation unit 4 acquires facility information from the facility server C (step S2). That is, the calculation unit 4 outputs a facility information acquisition instruction to the communication unit 1, causing it to send a facility information transmission request to the facility server C. The facility server C responds to the transmission request and transmits the medical facility information to the disaster prevention support device A. The communication unit 1 receives the facility information from the facility server C and outputs it to the calculation unit 4. Note that step S2 is the facility information acquisition process in this embodiment.

When the communications unit 1 obtains disaster prevention information for the target area and facility information for medical facilities in this manner, it generates a flood assessment matrix for various equipment within the medical facilities (step S3). This flood assessment matrix is a table that shows the relationship between the flood level of the medical facilities and the various equipment within those facilities in a matrix format.

For example, medical facilities have their own power supply systems. These systems activate when the normal power supply from the utility company is interrupted, providing power to necessary parts of the facility to maintain medical functions. The flood assessment matrix includes the relationship between such power supply systems and flood levels.

The relationship between the integrity of power supply equipment and the flood level depends on the height at which the various components of the power supply equipment are installed. Medical facilities have various other facilities besides power supply equipment, such as water supply equipment, sewage drainage equipment, rainwater drainage equipment, medical gas equipment, electronic medical records, elevators, disaster prevention centers, pharmaceuticals, medical supplies, and meals. The integrity of these various facilities depends on the installation height of the various components of each facility and the floor height of the building.

Then, the calculation unit 4 extracts the installation height and floor height for each building and various equipment in the medical facility from the building information included in the facility information, and compares the installation height and floor height with the flood height to perform a risk assessment (flood risk assessment) of the various equipment in the medical facility as shown in the evaluation matrix (step S4).

Figure 3 shows an example of a risk assessment table created by the calculation unit 4 as a result of the processing in step S4. The calculation unit 4 creates the risk assessment table by adding the evaluation results obtained from the processing in step S4 to the flood assessment matrix created in step S3, indicating normal (○), partially normal (△), or malfunction (×).

Once the risk assessment table is created in this manner, the calculation unit 4 obtains (extracts) the following information from the facility information as individual flood-related work content: the organizational structure of the medical facility, the work content of facility staff in each department during a flood, the person in charge of each task, the working hours for each task, and disaster prevention manuals (step S5). Then, the calculation unit 4 creates a disaster prevention action-related table based on this individual flood-related work content (step S6). This step S6 is the support information creation process in this embodiment.

Figure 4 shows an example of a disaster prevention action chart created in step S6. As illustrated, this chart shows the disaster prevention actions of various departments and staff members of a medical facility (disaster response headquarters, hospital director, management, general affairs and planning department, etc.) in the pre-flood stage, linked chronologically to flood stages based on river water levels and RRI information.

This disaster prevention action chart illustrates how, for example, a staff member in the General Affairs and Planning Division can check water levels and RRI information, and the administrative supervisor can issue an order to the General Affairs and Planning Division staff member to initiate flood control measures at the medical facility. It also shows how each department and facility staff, including the hospital director, can take necessary actions while monitoring trends in water levels and RRI information.

Furthermore, the disaster prevention action table shows that the flood stage changes sequentially based on water level and RRI information. The flood stage changes sequentially over time based on rising water levels and trends in RRI information, and changes gradually according to a predetermined lead time.

For example, in the example in Figure 4, the flood stage rises from Stage 3 to Stage 4-1 when the water level exceeds 2.0 m, and then rises from Stage 4-1 to Stage 4-12 when the water level exceeds 3.0 m. In other words, the example in Figure 4 shows that the flood stage changes during the time (lead time) from 13:40 to 14:50, when the water level changes from 2.0 m to 3.0 m.

The calculation unit 4, upon creating such a disaster prevention action-related table, evaluates whether the time required for disaster prevention actions by each department and facility staff member listed in the table (disaster prevention action time) falls within the assumed lead time for each flood stage (step S7). While disaster prevention actions within the lead time are carried out individually and in coordination by multiple organizations and facility staff members, it is anticipated that not all disaster prevention actions may be completed within the lead time.

The calculation unit 4 determines the consistency between the disaster prevention action time for each disaster prevention action, which is input from the operation unit 3 as an operation instruction for facility staff, and the lead time in the disaster prevention action-related table. Based on this consistency determination, the calculation unit 4 then determines which disaster prevention actions are inconsistent with the lead time in the disaster prevention action-related table.

Then, the calculation unit 4 adjusts the flood stage and the conditions (triggers) for changing the flood stage in the disaster prevention action-related table (step S8), based on the evaluation results in step S7, the hazard map of the disaster prevention information, weather information for the target area during past floods, and past flood response records and past inundation records included in the facility information. In other words, in step S8, the calculation unit 4 adjusts the conditions (triggers) for determining the lead time in the disaster prevention action-related table.

Then, the calculation unit 4 creates a disaster prevention timeline for floods based on the disaster prevention action-related table modified through step S8 (step S9). The disaster prevention timeline is an action plan showing who in each department of the medical facility will perform which disaster prevention action (implementation item) at which flood stage (timing) in the pre-flood phase. Step S9 is the support information creation process in this embodiment.

The calculation unit 4, upon creating a disaster prevention timeline, outputs the timeline (step S10). That is, the calculation unit 4 stores the disaster prevention timeline in the storage unit 2 and outputs it to the display unit 5 for screen display. Furthermore, based on operation instructions input from the operation unit 3, the calculation unit 4 outputs the disaster prevention timeline to the communication unit 1 for storage on the facility server C, or sends it to an external printer via the communication unit 1 for printing.

Figure 5 shows an example of a disaster prevention timeline created in Step S9. This timeline outlines the disaster prevention actions to be taken at each stage of flooding, for each facility staff member serving as an information dissemination hub. For example, the head nurse, one of the facility staff members serving as an information dissemination hub, is assigned the tasks of confirming patient transport status and communication methods with nursing staff at Stage 1, and confirming patient transport priority at Stage 2.

When the calculation unit 4 creates the disaster prevention timeline in step S9, it acquires the results of the disaster prevention drill based on the timeline as training information. This training information is input to the calculation unit 4 either by a disaster prevention officer (facility staff) operating the operation unit 3, or from the facility server C.

In medical facilities, a disaster prevention timeline is created using disaster prevention support device A, and disaster prevention drills are conducted at appropriate times according to the timeline. The results of these drills are then saved as part of the facility information on the facility server C, or input into the calculation unit 4 as part of the operation information by operating the operation unit 3.

When the calculation unit 4 receives a training information acquisition instruction from the operation unit 3, it acquires the training information from the operation unit 3 following this instruction, or through communication with the facility server C via the communication unit 1 (step S11), and temporarily stores it in the storage unit 2. Then, the calculation unit 4 determines whether or not an update to the disaster prevention timeline based on the training is necessary (step S12).

The calculation unit 4 compares the training information acquired in step S11 with the disaster prevention timeline created in step S9 to determine the need to update the disaster prevention timeline based on the training information. If the determination in step S12 is "Yes," meaning that the disaster prevention timeline needs to be modified, the calculation unit 4 executes step S8 again to readjust the flood stages and triggers to align with the training information.

The calculation unit 4 recreates (updates) the disaster prevention timeline by executing step S9 again based on the readjusted flood stages and triggers. However, if the determination in step S12 is "No," meaning that no modification to the disaster prevention timeline is necessary, the readjustment of flood stages and triggers and the recreation (update) of the disaster prevention timeline are not performed, and the creation of the disaster prevention action-related table and disaster prevention timeline is completed.

According to this embodiment, a disaster prevention action-related table is created based on disaster prevention information for the target area where the medical facility is located and facility information for the medical facility. Furthermore, a disaster prevention timeline for flood damage at the medical facility is created based on this disaster prevention action-related table. Therefore, this embodiment provides a disaster prevention support device A and a disaster prevention support method using the disaster prevention support device A that can support the creation of more practical disaster prevention plans than conventional methods.

Furthermore, according to this embodiment, in addition to creating a disaster prevention timeline as disaster prevention support information, a disaster prevention action-related table is also created. Therefore, according to this embodiment, not only can each facility staff member of a medical facility understand which disaster prevention actions to take and when, but they can also understand how facility staff members are coordinating with each other, thus supporting the creation of a more practical disaster prevention plan.

The present invention is not limited to the embodiments described above, and for example, the following modifications are possible.
(1) In the above embodiment, a case in which a medical facility responsible for regional medical care is designated as a disaster prevention target facility was described, but the present invention is not limited to this.

(3) In the above embodiment, disaster prevention information was obtained from external server B and facility information was obtained from facility server C, but the present invention is not limited thereto. Various methods for obtaining disaster prevention information and facility information are conceivable; for example, the information may be obtained in advance and stored in storage unit 2. Furthermore, the information necessary for creating the disaster prevention action-related table (essential information) may be treated as a single piece of information, rather than being separated into disaster prevention information and facility information.
