Description

[Technical Field]

[0001] The present invention relates to an evacuation simulation system that performs an evacuation simulation for evacuees within a facility. [Background technology]

[0002] Conventionally, there have been proposed techniques relating to simulations of evacuation from inside a building in the event of a disaster, etc. For example, Patent Document 1 discloses an evacuation simulation device that selects an evacuation route for evacuees based on the diffusion state of hazardous substances, position information of the evacuees, and multiple evacuation routes. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-027208 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the technology disclosed in Patent Document 1, an evacuation route is selected for each evacuee. Here, for example, in a hospital or nursing home, evacuees who are patients or require care may have illnesses, injuries, disabilities, etc., and an evacuation plan regarding evacuation time and evacuation route must be formulated according to the characteristics of each evacuee. Characteristics recorded in each evacuee's medical record, such as whether they can move independently, with assistance, in a wheelchair, or in a bed, can be reflected in the evacuation plan by referring to the medical record. However, characteristics of the evacuee that are not recorded in the medical record may affect evacuation behavior. Therefore, there has been a demand for an evacuation simulation that more accurately reflects the characteristics of the evacuees.

[0005] The present invention has been made in view of the above-mentioned problems, and aims to provide an evacuation simulation system that can obtain evacuation simulation results that more accurately reflect the characteristics of evacuees. [Means for solving the problem]

[0006] The evacuation simulation system of the present invention comprises an evacuation vulnerable person index acquisition unit that acquires an evacuation vulnerable person index that indicates the difficulty of an evacuee to evacuate based on objective information about the evacuee and additional information obtained by observing the evacuee, and a simulation processing unit that simulates the time required for the evacuee to evacuate based on the evacuation vulnerable person index. [Effects of the Invention]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiments, and various modifications are possible without departing from the spirit of the present invention. Furthermore, the present invention includes all possible combinations of the configurations shown in the following embodiments. Furthermore, the device shown in the drawings is an example of the device of the present invention, and the device of the present invention is not limited to the device shown in the drawings. Furthermore, in each drawing, parts with the same reference numerals are the same or equivalent, and this is common throughout the entire specification.

[0010] Embodiment (System Configuration) FIG. 1 is a diagram showing an example of the configuration of an evacuation simulation system according to an embodiment. The evacuation simulation system 1 is a system that performs a simulation of the evacuation of evacuees in a building. In this embodiment, the configuration and functions of the evacuation simulation system 1 will be described using an example in which the building is a hospital H and the evacuees are inpatients at the hospital H. The evacuation simulation system 1 of this embodiment is communicatively connected to a terminal device 20 installed in the hospital H via a network N that is a dedicated line or a public line. A camera 30 communicatively connected to the terminal device 20 is installed in the hospital H.

[0011] (Evacuation Simulation System 1) The evacuation simulation system 1 includes an evacuation vulnerable person index acquisition unit 2, a simulation processing unit 3, a calculation unit 4, an objective information acquisition unit 5, an additional information acquisition unit 6, an identification information setting unit 7, a room allocation input unit 8, a display data generation unit 9, a memory unit 10, and initial value data 11 and an evacuee information DB 12 stored in the memory unit 10.

[0012] The vulnerable evacuation index acquisition unit 2 acquires the vulnerable evacuation index from the calculation unit 4, which will be described later. In this embodiment, the acquired vulnerable evacuation index is stored for each evacuee in the evacuee information DB 12. Here, the vulnerable evacuation index is a value indicating the difficulty of an evacuee's evacuation, and in this embodiment, the higher the value, the greater the difficulty of evacuation. The difficulty of evacuation is influenced by objective factors, including illness or injury status, recorded in medical records, etc. For example, the difficulty of evacuation increases in the order of the means of transportation required for evacuation: walking alone, walking with walking aids, wheelchair, and bed. However, which means to use can be determined from objective factors recorded in medical records, etc. Furthermore, the difficulty of evacuation is also influenced by mental characteristics, behavioral characteristics, or personality characteristics that are not reflected in objective factors, such as the evacuee's medical records. For example, an evacuee who is unwilling to evacuate due to depression or a tendency to feel down, etc., will take longer to evacuate than other evacuees who are able to walk on their own, making evacuation more difficult for them, even if they are able to walk on their own. Such characteristics that are not reflected in the evacuee's objective information are information regarding the prediction of evacuation behavior obtained by people around the evacuee, such as doctors, nurses, and caregivers, observing the evacuee from the perspective of evacuation for a predetermined period of time, and this information is referred to as additional information in this embodiment. In this embodiment, an evacuation vulnerable person index is determined for each evacuee based on the objective information and additional information. For example, the evacuation vulnerable person index can be set to [value N derived from objective information] × [value M derived from additional information].

[0013] One or more parameters are used to derive the value N from the objective information. Examples of parameters include the above-mentioned means of transportation, the name and location of the injury or illness, the degree of recovery, and the number of days until the expected date of discharge. Also, one or more parameters are used to derive the value M from the additional information. Examples of parameters include activity level, sociability, and bipolar state. In this embodiment, since the building to be evacuated is hospital H, medical records are used as the objective information. However, the source of objective information is not limited to medical records, and information according to the type of building and the purpose of use of the evacuees (users) is used. For example, if the building is a school, information such as a student list is used as the objective information, and if the building is a nursing home, nursing records, etc. are used as the objective information. Also, it does not matter whether the objective information and the additional information are recorded in a single electronic file.

[0014] The simulation processing unit 3 simulates the time required for evacuation of evacuees based on the index of vulnerable evacuees. Furthermore, the simulation processing unit 3 of this embodiment simulates the evacuation actions of evacuees and generates a simulation image showing the evacuation actions. The simulation processing unit 3 simulates the evacuation actions of multiple evacuees using, for example, multi-agent simulation technology. The simulation processing unit 3 executes the simulation based on the index of vulnerable evacuees input from the index acquisition unit 2 for vulnerable evacuees, the evacuee information DB 12, and the initial value data 11.

[0015] Calculation unit 4 calculates the index of vulnerable evacuees based on the objective information input from objective information acquisition unit 5 and the additional information input from additional information acquisition unit 6.

[0016] The objective information acquisition unit 5 acquires objective information. In this embodiment, an example will be described in which the objective information is medical record information of patients at Hospital H who are evacuees. The objective information acquisition unit 5 acquires medical record information 24 stored in terminal device 20 at Hospital H via network N. The objective information acquisition unit 5 analyzes the acquired medical record information 24 and extracts information to be used in calculating the vulnerable evacuee index as objective information. The objective information acquisition unit 5 inputs the acquired objective information for each evacuee to the calculation unit 4.

[0017] The additional information acquisition unit 6 acquires additional information. In this embodiment, the additional information acquired via the network N includes information input to the terminal device 20 by a doctor, nurse, or the like, and information extracted from images of evacuees captured by the camera 30. However, the additional information is not limited to this, and may be acquired based on the usage status of devices used in daily life, such as an IC card type television or lighting.

[0018] The identification information setting unit 7 sets identification information for each evacuee to distinguish one or more evacuees from other evacuees in the simulation image generated by the simulation processing unit 3. In a simulation image including the evacuation actions of multiple evacuees, the identification information is used to make it easier for a user viewing the simulation image to focus on a specific evacuee. The identification information setting unit 7 may accept input of the identification information via an input device such as a mouse, keyboard, or touch panel provided in the evacuation simulation system 1, or may obtain the identification information input to the terminal device 20 via the network N.

[0019] The room allocation input unit 8 receives input for allocating evacuees to a plurality of rooms in the building. In this embodiment, the allocation of patients to a plurality of hospital rooms in the hospital H is input to the room allocation input unit 8. Allocation information for existing hospitalized patients to each room, as recorded in medical records or the like, is input from the terminal device 20 to the room allocation input unit 8 via the network N, and further, changes to the allocation are input to obtain simulation results for when the room allocation is changed.

[0020] The display data generation unit 9 generates display data to be displayed on a display device such as a display, using the simulation image generated by the simulation processing unit 3. The display data generation unit 9 of this embodiment generates display data exemplified in Figs. 3 to 6, which will be described later.

[0021] The memory unit 10 stores initial value data 11 and an evacuee information DB 12. The memory unit 10 also stores data that is read and written by each functional unit of the evacuation simulation system 1 and used in the processing of each functional unit. The memory unit 10 is a computer-readable recording medium, and is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, or an external storage medium such as a memory card, or a combination thereof.

[0022] The initial value data 11 are initial values ​​of data used by the simulation processing unit 3 when executing a simulation. The initial value data 11 are initial values ​​of data related to the building, evacuees, and caregivers during evacuation. The building information includes, for example, map information such as the building's floor plan, room layout, and room type, as well as evacuation routes such as elevators and stairs. The evacuee information includes, for example, the evacuation speed depending on the means of transportation such as walking alone, walking with walking aids, wheelchair, or bed, and the time required to start evacuation. The evacuation caregiver information includes, for example, the number of caregivers and the role of each caregiver in guiding the evacuation.

[0023] The evacuee information DB12 is a database that associates evacuees with vulnerable evacuation indexes. In this embodiment, patients at Hospital H are associated with vulnerable evacuation indexes. FIG. 2 is a diagram illustrating an example of the configuration of the evacuee information DB according to this embodiment. The evacuee information DB12 of this embodiment includes an evacuee ID 121, a name 122, medical record information 123, additional information 124, a vulnerable evacuation index 125, identification information 126, and a room ID 127. The evacuee ID 121 is information that uniquely identifies a patient who is an evacuee. The name 122 is the name of the patient. The medical record information 123 indicates the presence or absence of medical record information, which is objective information. In FIG. 2, 1 indicates the presence of medical record information and 0 indicates the absence of medical record information. The additional information 124 indicates the presence or absence of additional information and is represented by 1 if the additional information is present and 0 if the additional information is absent. The vulnerable evacuation index 125 is the vulnerable evacuation index acquired by the vulnerable evacuation index acquisition unit 2. In the example of Fig. 2, the index of vulnerable evacuees is indicated by the numbers 1 to 3, but the granularity of the numerical value representing the index of vulnerable evacuees is not limited to this. Identification information 126 indicates whether or not identification information has been set for the evacuee, and is indicated by 1 if it has been set and 0 if it has not. Room ID 127 is information that identifies the room in Hospital H assigned to the evacuee. It is sufficient that the evacuee information DB12 includes at least the evacuee ID 121 that uniquely identifies the evacuee and the index of vulnerable evacuees 125.

[0024] (Terminal device 20) A terminal device 20 in hospital H will be described with reference to Fig. 1. The terminal device 20 is a device operated by a doctor, a nurse, a staff member, or the like. One or more terminal devices 20 are installed in hospital H or carried by a doctor or the like in hospital H. The terminal device 20 is, for example, a dedicated or general-purpose computer device, a tablet terminal, a smartphone, or the like.

[0025] The terminal device 20 includes a display unit 21, an input unit 22, a control unit 23, and medical record information 24. The display unit 21 is a display device such as a liquid crystal display, an organic EL display, or electronic paper. In this embodiment, the display unit 21 displays a simulation image. The input unit 22 is an input device such as a keyboard, a mouse, or a touch panel. The control unit 23 controls each functional unit of the terminal device 20. The medical record information 24 is medical record information of a patient who is an evacuee. The medical record information 24 is stored in a storage unit which is a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, EEPROM, or an external storage medium such as a memory card, or a combination thereof.

[0026] (Camera 30) The camera 30 is a device that captures images inside the hospital H. One or more cameras 30 are installed in the hospital H's patient rooms, corridors, stairs, elevators, entrances, or courtyards to capture images of patients who will become evacuees. Image analysis is performed on the images of the evacuees captured by the camera 30, and facial recognition of the evacuees and extraction of additional information for each evacuee are performed from the analyzed images. A known technique is used for the image analysis, and the technique is not particularly limited. For example, if images of patient X who can walk independently captured over a predetermined period by the camera 30 installed in a hospital room show that patient X has an active characteristic of frequently conversing with people around him, additional information is obtained that indicates that the patient has a low level of difficulty in evacuating (easily evacuated). For example, if images of patient Y who can walk independently show that patient Y tends to avoid conversations with people around him, additional information is obtained that indicates that patient Y is reluctant to evacuate and has a high level of difficulty in evacuating (difficult to evacuate). Information extracted from the image that is the source of the additional information includes, but is not limited to, the amount of conversation with people around, as well as the amount of food eaten, the number of rehabilitation sessions, the number of visitors, etc.

[0027] Image analysis of the image captured by the camera 30 and extraction of additional information from the analyzed image may be performed by the additional information acquisition unit 6 of the evacuation simulation system 1, by the camera 30, by the terminal device 20, or in a distributed manner.

[0028] (Evacuation simulation) Fig. 3 is a diagram showing an example of a display of a simulation screen according to an embodiment. Fig. 3 shows an example in which a simulation screen 40 is displayed on the display unit 21 of the terminal device 20. The simulation screen 40 shown in Fig. 3 includes a map 41, and a display area E1 and buttons B1 to B4 arranged on the right side of the map 41. The map 41 includes, for example, a room 42, an evacuee symbol 43 representing an evacuee, a nurse station 44, an emergency staircase 45, and an emergency elevator 46. In the room 42, a plurality of evacuee symbols 43 representing patients hospitalized in the room are shown.

[0029] Button B1 is a button for instructing to carry out a simulation. Button B2 is a button for instructing to set the simulation conditions. When button B2 is pressed, a screen (not shown) for setting the simulation conditions is displayed, and information to be recorded in the evacuee information DB can be entered. Button B3 accepts an instruction input to reflect the conditions set by pressing button B2 on the simulation screen 40 displayed on the display unit 21. When button B3 is pressed, the updated simulation screen 40 is displayed. Button B4 accepts an instruction to close the simulation screen 40.

[0030] Display area E1 displays the time required for evacuation obtained by the simulation.

[0031] The simulation screen 40 may be displayed using a dedicated application installed on the terminal device 20, or may be displayed using a general-purpose browser. Information entered into buttons B1 to B4 on the simulation screen 40 is input to the evacuation simulation system 1 via the network N. Display data generated by the display data generation unit 9 of the evacuation simulation system 1 based on this input is input to the terminal device 20 via the network N and displayed as the simulation screen 40.

[0032] Specifically, when a user such as a facility manager of Hospital H checks the simulation screen 40 displayed on the display unit 21 of the terminal device 20 and presses button B1, an instruction to start the simulation is input to the evacuation simulation system 1. The evacuation simulation system 1 transmits the time required for evacuation obtained by executing the evacuation simulation to the terminal device 20. The simulation screen 40 displayed on the display unit 21 of the terminal device 20 displays the time required for evacuation in the display area E1.

[0033] In this embodiment, the evacuation simulation system 1 simulates the time required for evacuation of evacuees based on an index of vulnerable evacuees, which indicates the difficulty of evacuation for evacuees, based on objective information about the evacuees and additional information obtained by observing the evacuees for a predetermined period of time. In this embodiment, the objective information is information recorded in medical records, etc., and the additional information is information obtained by doctors or others observing hospitalized patients for a predetermined period of time or information obtained by image processing of camera footage. The accuracy of the evacuation simulation can be improved by using not only the medical record information recorded for each hospitalized patient at Hospital H and made public to predetermined members within the hospital, such as doctors or staff, but also the index of vulnerable evacuees that reflects the additional information.

[0034] (Evacuation simulation image) An example of displaying the evacuation actions of evacuees as simulation images (moving images or still images) in a time series will be described. FIGS. 4 to 6 are diagrams showing display examples of a simulation screen according to an embodiment in a time series. The evacuation actions progress in the order of FIGS. 4, 5, and 6. In FIGS. 4 to 6, a marker 47 that can distinguish the evacuee symbols 43 corresponding to the evacuees for which identification information has been set is displayed with a star-shaped icon. The marker 47 in FIGS. 4 to 6 may be a star-shaped icon, but may be other shapes or characters. Furthermore, the marker function may be realized by making the color or shape of the evacuee symbol 43 for which identification information has been set different from that of the other evacuee symbols 43. Furthermore, the simulation screen 40 may include, in addition to the evacuee symbols 43, an assistant symbol indicating an assistant.

[0035] The evacuee symbols 43 may be displayed in different ways, such as by color-coding them according to the index of vulnerable people to evacuation. Also, a threshold may be set for the time required for evacuation, and evacuee symbols 43 that cause the threshold to be exceeded may be displayed in a different way from other evacuee symbols 43.

[0036] FIG. 7 is a diagram illustrating an example of initial value data according to an embodiment. FIG. 7 illustrates, among the initial value data 11, movement speeds and evacuation routes corresponding to the evacuation vulnerable index. The more difficult it is for a person to evacuate, the larger the value of the evacuation vulnerable index. Here, the simulation conditions are simplified, and evacuation vulnerable indexes 1 and 2 indicate evacuees who can walk on their own, while evacuation vulnerable index 3 indicates evacuees who move in a wheelchair with the assistance of a caregiver. Although evacuees with evacuation vulnerable indexes 1 and 2 are both able to walk on their own, due to the influence of the additional information described above, their evacuees have different evacuation vulnerable indexes and different initial values ​​of their movement speeds. The movement speed of evacuation vulnerable index 2, which is more difficult for evacuees to evacuate than evacuation vulnerable index 1, is set to be slower than the movement speed of evacuation vulnerable index 1.

[0037] 4 shows the state before the evacuation began, and each of rooms 42a to 42e is shown with an evacuee symbol 43 corresponding to the patient in that room. The numbers 1 to 3 attached to the evacuee symbols 43 represent the evacuation vulnerable index.

[0038] When the simulation of evacuation operations is started, the simulation of evacuation operations is first executed based on the initial value data 11 shown in FIG. 7. As shown in FIG. 5, the evacuee symbols 43 move and the evacuation operations are displayed on the simulation screen 40. The evacuation operations may be displayed as a moving image or may be displayed frame by frame. FIG. 5 shows the evacuation operations of the evacuee symbols 43 in rooms 42a to 42c.

[0039] Fig. 6 shows the evacuation behavior following Fig. 5. Fig. 6 shows the evacuation behavior of evacuee symbols 43 in rooms 42d and 42e. In Fig. 7, evacuee symbol 43 with an evacuation vulnerability index of 3, for which the emergency elevator is set as an evacuation route, is waiting in front of emergency elevator 46, while evacuee symbol 43 with an evacuation vulnerability index of 2 is moving up emergency stairs 45.

[0040] In this embodiment, a simulation screen 40 is displayed with a marker 47 added to one or more of the evacuee symbols 43, making it easier for users such as those formulating evacuation plans to check the movements of evacuees and others who should be closely monitored during evacuation.

[0041] After checking the simulation image of the evacuation behavior, the user may change the simulation conditions and instruct to run the simulation again. For example, the user may change the movement speed or evacuation route in the initial value data 11 shown in Fig. 7. In addition, the user may change the information for each evacuee in the evacuee information DB.

[0042] The user may also input a revised room assignment and instruct the simulation to be executed again. Specifically, the user presses button B2 shown in FIG. 3 to display a setting screen (not shown) to input changes to the rooms of each evacuee. The input information is input from the terminal device 20 to the room assignment input unit 8 of the evacuation simulation system 1, and the simulation processing unit 3 executes an evacuation simulation based on the revised room assignment. For example, if the simulation results in a shorter evacuation time than before the change, changes to the room assignments of patients in Hospital H may be considered. The results of the evacuation simulation may also be used in room assignments when admitting new hospitalized patients. In this way, the evacuation simulation system 1 of this embodiment can contribute to the consideration of room assignments that contribute to rapid evacuation. Furthermore, room assignments may be input by increasing or decreasing the number of evacuees, for example, by excluding patients scheduled for discharge or adding patients scheduled for admission. By executing evacuation simulations by changing conditions such as the number of evacuees or the presence or absence of specific evacuees, the simulations can be used to consider future evacuation plans or room assignments.

[0043] The functional units constituting the evacuation simulation system 1 shown in this embodiment may be realized by one computer device or by multiple computer devices, and the terminal device 20 may be included as part of the multiple computer devices.

[0044] Furthermore, the building that is the subject of the evacuation simulation is not limited to the hospital H, but may be a building for another purpose. The evacuation simulation system 1 can be applied to buildings other than the hospital H, such as nursing homes, retirement homes, and schools, where additional information can be obtained by observing evacuees for a predetermined period of time, thereby achieving the effect of obtaining a more accurate evacuation simulation.

[0045] Furthermore, the initial value data 11 used in the evacuation simulation and the parameters and algorithms (hereinafter collectively referred to as parameters, etc.) used to calculate the index of vulnerable evacuees may be shared among multiple hospitals. For example, a single evacuation simulation system 1 may be connected to terminal devices 20 of multiple hospitals H, and the initial value data 11 and parameters, etc. may be stored for each hospital. When performing an evacuation simulation, the initial value data 11 and parameters, etc. of the target hospital may be used, or those of other hospitals may be used, or values ​​obtained by statistically processing both may be used. By making it possible to use the initial value data 11 and parameters, etc. of other hospitals, or values ​​reflecting them, more accurate simulation results can be obtained even when performing an evacuation simulation for a hospital with little simulation experience. Furthermore, by making it possible to share the index of vulnerable evacuees among hospitals, when a patient is transferred to another hospital, the hospital to which the patient is transferred can use the index of vulnerable evacuees reflecting the patient's additional information in the simulation, thereby quickly obtaining accurate evacuation simulation results.

[0046] (Variation) The index of vulnerable evacuation persons may reflect values ​​based on other information in addition to objective information and additional information. For example, the index of vulnerable evacuation persons may be corrected according to the difference between the time actually required for evacuation during an evacuation drill and the time obtained by the evacuation simulation performed by the evacuation simulation system 1. The correction of the index of vulnerable evacuation persons may be performed not only on the index of vulnerable evacuation persons who actually participated in an evacuation drill, but also on the index of vulnerable evacuation persons who have characteristics in common with the evacuees who participated in an evacuation drill.

[0047] Furthermore, the evacuation simulation system 1 may perform machine learning or deep learning using the evacuation simulation conditions and the evacuation time obtained from the evacuation simulation to optimize the index of vulnerable evacuees. For example, based on the learning results, weighting of multiple parameters constituting the objective information and additional information is set. By using the index of vulnerable evacuees obtained in this way, a more accurate evacuation simulation can be performed.

[0048] Furthermore, instead of or in addition to the evacuation vulnerability index for individual evacuees, a group evacuation vulnerability index, such as that for multiple people in a hospital room who are likely to evacuate together, can be calculated and used to simulate the time required for evacuation. The group evacuation vulnerability index is not a simple sum of individual evacuation vulnerability indexes, but is a group evacuation vulnerability index that reflects the difficulty of evacuation due to the combination of evacuees. Depending on the location of injuries or the type of illness, combining multiple people may hinder evacuation. Conversely, when attempting to evacuate multiple people who require wheelchairs, an equal number of caregivers are required. However, if there is someone in the same group who can walk, they can help in place of the caregiver, making evacuation easier. In other words, because evacuation conditions change depending on the people in the group, calculating the group evacuation vulnerability index is effective. Furthermore, by setting up a notification when the group evacuation vulnerability index exceeds a predetermined value, decisions can be made, such as replacing the evacuees with people from another group.
