Description

  The present invention relates to an evacuation support system.

  There is a system to support evacuation guidance for people in the facility when a disaster such as an earthquake or fire occurs in a facility such as an office building, commercial building, condominium, underground facility, station facility, stadium, theater, or stadium. Various proposals have been made.

  As such a system, various disaster information is received, the type and location of the disaster that occurred are recognized, and the location information of multiple people is acquired from mobile terminals such as mobile phones owned by individuals, Based on such information, an evacuation support system has been proposed in which an evacuation route is communicated to a mobile terminal of each individual to guide evacuation.

  In addition, for example, Patent Document 1 includes an information management unit that manages supporter information indicating whether or not each evacuation target person is a supporter who performs evacuation guidance support at the time of a disaster, and position information of each evacuation target person. A position detection unit to acquire, an evacuation delay person detection unit that determines whether each evacuation target person is highly likely to be delayed in evacuation, supporter information managed by the information management unit, and a position detection unit An evacuation guidance support system including an evacuation guidance supporter allocating unit that allocates a supporter to an evacuation delayed person based on the acquired position information and the detection result of the evacuation delay person detecting unit is disclosed.

  In the evacuation guidance support system described in Patent Document 1, it is possible to effectively support the evacuation guidance of a person who is highly likely to be delayed.

  However, the conventional evacuation support system merely presents information on the evacuation route to each refugee individually. In this way, when evacuation routes are individually presented to individual evacuees, each evacuee takes action with the highest priority given to individual evacuation, resulting in traffic congestion on the evacuation route, There were cases where evacuation was delayed not only for each individual but for the whole.

  Also, even if you try to organize each organization or group using the conventional disaster prevention training mechanism, if the role manager is not on the spot at the time of the disaster, you can not act as disaster prevention training, There was a problem that congestion and panic occurred on the evacuation route, and the evacuation was delayed as a whole.

  Further, in the system described in Patent Document 1, the position information of the evacuation target persons is obtained, the evacuation target persons are assigned roles at the time of evacuation, and the number of persons who cannot evacuate is reduced. Cannot be made efficient, and the problem of slow evacuation as a whole has not been solved.

  In other words, the presence of a leader is considered essential to lead the organization as an organization and to promote efficient actions as a whole. Its existence is particularly required in emergency situations such as disasters and evacuations that require emergency. In the absence of a leader, it is assumed that each individual performs selfish behavior. For example, in the event of a disaster such as a building, if each individual takes a selfish action to try to save himself / herself, it is expected that traffic congestion will occur on the evacuation route, etc., resulting in a delay in evacuation However, it is assumed that evacuation efficiency cannot be improved as a whole, such as people who are evacuated late or who cannot evacuate. In order to deter such selfish behavior, it is desirable to have leaders in the group, to lead them, and to take appropriate actions.

  Therefore, the present invention categorizes evacuation target persons and assigns an appropriate role so as to efficiently enable evacuation as a whole evacuation target person, and can evacuate all evacuation target persons quickly. The purpose is to provide.

  In order to achieve such an object, an evacuation support system according to the present invention includes a portable terminal carried by a person to be evacuated, a relay device disposed in a facility so as to be able to wirelessly communicate with the portable terminal, and a communication with the relay device. An evacuation support system that supports evacuation of a person to be evacuated in a facility, wherein the mobile terminal transmits owner information of the mobile terminal to the relay device Data transmission means, and the relay apparatus includes data transmission means for transmitting relay information in which the owner information is associated with location information of the relay apparatus to the evacuation support apparatus, and the evacuation support apparatus includes the relay information Storage means for storing log data in which the acquisition time of the relay information is associated with information, a first table that defines the relationship of roles that can be handled during evacuation for each evacuation target, and the number of members of the evacuation group Accordingly, the second table that defines the required number of persons for each role, and the location of the person to be evacuated is specified based on the log data when an event requiring evacuation occurs, and the first table and the second table Based on the table, the evacuation group organization means for organizing the evacuation group so as to satisfy the required number of people for each role for each area in the facility defined in advance, and the evacuation support information about the organized evacuation group is provided for the evacuation target person Data transmitting means for transmitting to the portable terminal.

  According to the present invention, all evacuation subjects can be evacuated quickly.

  Hereinafter, a configuration according to the present invention will be described in detail based on the embodiment shown in FIGS.

[Configuration of evacuation support system]
First, the premise evacuation support system will be described. FIG. 1 is an explanatory diagram schematically showing the layout of an office building composed of a four-story building S and a building N and individual (evacuation target) position information. FIG. 2 is a role table for evacuation support, in which five individuals (id_A, B, C, D, E), each assigned a different ID, are responsible for evacuation (“leader”, "Relief team", "craft team").

  In the example of FIG. 1, at a certain time point (13:40 time point), id_B and id_D are in the area on the 4th floor of the S building (hereinafter referred to as 4F-S). In the example, one person is in the area on the third floor of the S building and id_C and id_E are on a business trip. In the following description, it is assumed that the floors of the S building and the N building constitute one area, and eight areas are defined in advance. In addition, it is assumed that five persons id_A to E are normally in 4F-S.

  In places where predetermined individuals such as office buildings enter and exit, evacuation drills and the like are often carried out regularly. Similar to the regular implementation of evacuation drills, the evacuation support system often has a role for evacuation support.

  Evacuation drills are often scheduled for evacuation drills in advance, and if the absence of a person listed in the role table for evacuation support is expected, a substitute person should be assigned. It can be implemented. However, in reality, since an event that requires evacuation occurs suddenly, it is difficult to assign a substitute person in advance.

  Moreover, when evacuation is required, each individual of the group to evacuate is not necessarily in a position predicted in advance. For example, as shown in FIG. 1, out of 5 people who are supposed to be in the 4th floor area (4F-S) of S building, one is in the other area (3F-S), and others If these two persons are out of the area during a business trip or the like, it becomes impossible to evacuate by fulfilling the role of the role table assigned in advance as shown in FIG.

Further, the data transmission / reception unit 23 receives the evacuation guidance data transmitted from the evacuation support server 30, and the data transmission / reception unit 22 transmits the evacuation guidance data to the mobile terminal 10.

  The hardware configuration of the relay device 20 includes a CPU, a memory, an antenna, a wireless communication unit that communicates with the short-range wireless technology using the antenna, a communication unit that connects to the evacuation support server 30 by wire or wirelessly, and the like. An information processing apparatus or a microcontroller in which these are electrically connected by a bus line such as an address bus or a data bus can be used. It is also preferable that the relay device 20 be provided in an installation in a facility, for example. For example, it can be provided in a multifunction device, an LED tube, or the like installed in a facility.

  The data transmitter / receiver 22 of the relay device 20 receives the personal ID transmitted from the data transmitter 12 of the mobile terminal 10.

  Next, the data transmission / reception unit 23 of the relay device 20 transmits the data (referred to as relay data) associated with the personal ID and the location ID received by the data transmission / reception unit 22 to the evacuation support server 30 via a network (such as a LAN). Send. The relationship between the place ID and the area is defined in advance on the evacuation support server 30 side.

  The evacuation support server 30 includes a data receiving unit 31 that receives relay data from the relay device 20, a log data storage unit 32 that is a storage unit that stores log data, a timer 33 having a clock function, and an evacuation group determination process. And a role table 35 (first table) that defines the relationship between the analysis processing unit 34 that functions as an evacuation group organization means for executing evacuation group information transmission processing and the like, and the roles that can be handled in evacuation for each evacuation target person And an evacuation group table 36 (second table) that defines the required number of persons for each role according to the number of members of the evacuation group, a meeting place table 37 (third table) that defines a meeting place for each area, and evacuation And a data transmission unit 38 that transmits the guidance data to the relay device 20.

  The hardware configuration of the evacuation support server 30 includes a CPU, a memory, an auxiliary storage device (HDD, etc.), an antenna, a wireless communication means that communicates with the short-range wireless technology using the antenna, and a wired or wireless connection with the evacuation support server 30. An information processing apparatus that includes a communication unit that is connected to each other through a bus line such as an address bus or a data bus can be used.

  The data receiving unit 31 of the evacuation support server 30 acquires the time when the relay data received from the relay device 20 is received from the timer 33 and associates these data (referred to as log data) with the log data storage unit. 32. For the time information, the mobile terminal 10 or the relay device 20 may be provided with a timer, and the time information may be added to the personal ID or relay data for transmission.

  FIG. 4 shows an example of log data stored in the log data storage unit 32. As shown in FIG. 4, the log data includes time, personal ID, and place ID. According to FIG. 4, for example, it is determined that the evacuation target person whose personal ID is id_A moves from 3F_S → 3F_N → 3F_S from the time 13:15:20 to 13:15:40. it can.

  The analysis processing unit 34 of the evacuation support server 30 executes an evacuation group determination process, which will be described later, based on the log data stored in the log data storage unit 32 and the tables 35 to 37, and determines an evacuation group. In the evacuation group determination process, evacuation guidance data including a meeting place for evacuation guidance is generated. Further, the analysis processing unit 34 executes an evacuation group information transmission process and an evacuation route transmission process.

  Then, the data transmission unit 38 of the evacuation support server 30 transmits the evacuation guidance data to the relay device 20, and the data transmission / reception units 22 and 23 of the relay device 20 transmit this to the mobile terminal 10.

In addition, the evacuation support system 100 may include a unit that performs disaster occurrence detection performed by the disaster detection system 200.

  FIG. 5 shows an example of the role table 35 provided in the evacuation support server 30. The role table 35 is a table in which information about roles that the individual can handle is associated with each individual ID. In this embodiment, three roles are defined: “captain” who is the leader of the evacuation group, “rescue team” that performs rescue activities such as injuries, and “work team” that performs work activities such as removing obstacles. However, the role classification method and the number of classifications are not limited to this example.

  The example shown in FIG. 5 indicates that the person with the personal ID id_A has the ability to play any of the roles of “captain”, “rescue team”, and “work team”. In addition, it is shown that the person of id_B can play the role of “rescue team”, and the person of id_C shows that it can play the role of “work team”. It shows that it cannot play the role of.

  FIG. 6 shows an example of the evacuation group table 36 provided in the evacuation support server 30. The evacuation group table 36 is a table in which the number of members of the evacuation group and the number of roles required for each number of members are associated. It shows that the number of “Relief Team” and “Work Team” increases as the number of evacuation group members increases. Each evacuation group does not have to be in charge of all roles, but at least one “captain” is essential.

  The meeting place table 37 provided in the evacuation support server 30 stores the meeting place in the area for each area.

  Although the example in which the evacuation support system 100 includes the relay device 20 has been described so far, for example, when the mobile terminal 10 has a GPS function and has means capable of acquiring location information of the mobile terminal itself. The mobile terminal 10 may transmit the personal ID and the position information directly to the evacuation support server 30. In this case, the evacuation support server 30 can distribute the evacuation guidance data directly to the mobile terminal 10, whereby the evacuation support system 100 without the relay device 20 can be obtained.

[Evacuation group decision processing]
An evacuation support process executed by the evacuation support system 100 described above will be described. First, an evacuation group determination process for organizing an evacuation group will be described. 7 and 8 show a flowchart of the evacuation group determination process.

  First, the flowchart of FIG. 7 will be described. The analysis processing unit 34 of the evacuation support server 30 determines the position information of each individual based on the location ID of the latest log data (S101).

  Next, for each area, the number of role members is calculated based on the information of the evacuation target persons in each area and the role table 35 (S102). That is, the number of persons in charge of the “captain”, “rescue team”, and “work team” is calculated based on the information on the evacuation target determined for each area. As described above, depending on the individual, a plurality of roles can be assigned. Therefore, it is preferable to calculate a combination having the largest number of persons in charge.

  Next, referring to the evacuation group table 36, it is determined whether the number of persons in charge in each area satisfies the necessary number of persons for each role specified in the evacuation group table 36 for each area (S103). The area number X indicates the number of areas from 1 to X.

  Here, the area satisfying the necessary number of roles condition (S103: Y) is the condition achievement area (S104), while the area not satisfying the number of roles condition (S103: N) is the condition. It is set as an unachieved area (S105).

  After determining in S103 for all areas (S106: Y), it is determined whether all areas are condition achievement areas (S107).

  Here, when all the areas are condition achievement areas (S107: Y), each area becomes one evacuation group (original 1 area = 1 evacuation group). Then, the total number of people in each area (each evacuation group) is calculated (S108). Then, the data transmission unit 38, for each individual in each area, as the evacuation guidance data, based on the influence number of the area, which is the total number of people in each area (total number of people in the evacuation group), and the meeting place table 37 Then, a predetermined meeting place for each area is transmitted (S109). At this time, if the person is in charge of a role, it is preferable to transmit the role in charge. In addition, since the different content is transmitted with respect to the evacuation subject who is the “captain” as described later, the transmission process here is not essential.

  On the other hand, if there is an area where even one of the conditions cannot be achieved (S107: N), the process proceeds to the flowchart of FIG.

  The flowchart of FIG. 8 will be described. First, it is determined whether there is even one condition achievement area (S201). If there is a condition achievement area (S201: Y), then the number of condition unachieved areas (Z) is counted (S202).

  For this unachieved area, the following processing is executed in order from the unachieved area with the smallest area number. First, the areas where the conditions have not been achieved are arranged in ascending order of the area number X (S203).

  Next, the check count C is set to an initial value C = 0 (S204), the check count is incremented, and the processing of S206 to S209 is executed for the number of unachieved areas (S205, S210).

  For each condition unachieved area, the condition unachieved area number is replaced with an approximate value of the condition attainment area number (S206). That is, the condition unachieved area is added to the area where the condition is achieved in the adjacent area (two areas are merged into one area). Note that the positional relationship (distance between areas) of each area may be set in advance.

  Thereafter, the number of role members in the condition achievement area to which the condition unachieved area is added is calculated (S207), and it is determined whether this condition achievement area still achieves the necessary number of roles condition (S208). When the required number of roles condition is achieved (S208: Y), this is set as the condition achievement area. In this way, since the composition is incorporated in an area that is approximate in position, rapid group composition is possible, and the amount of personal movement can be reduced. This reduces the condition unachieved area.

  The same procedure is repeated for each condition unachieved area (S205 to S210). In this way, when the condition unachieved area is incorporated into the condition attainment area and the conditions can be achieved for all areas, each area including an area composed of a plurality of areas is regarded as one evacuation group. Become. Then, the total number of people in each area (each evacuation group) is calculated (S212).

  Then, the data transmission unit 38, for each individual in the area, as the evacuation guidance data, based on the influence number of people in the area (total number of people in the evacuation group) and the meeting place table 37 as the total number of people in each area, A predetermined meeting place for each area is transmitted (S213). The meeting place at this time may be a meeting place of the condition achievement area from the beginning. At this time, if the person is in charge of a role, it is preferable to transmit the role in charge. In addition, since the different content is transmitted with respect to the evacuation subject who is the “captain” as described later, the transmission process here is not essential.

  On the other hand, when the condition achievement area is 0 (S201: N), or when the conditions for the number of roles cannot be achieved by the process added to the approximate area (S208: N), the evacuation group table 36 is changed (S211). ). Specifically, a process for reducing the number of persons required for each role is performed. The change in the number of people in the evacuation group table 36 may reduce the number of people required for various roles, but it is possible to encourage the group to act as a group. It becomes possible to efficiently evacuate the entire evacuation target person.

[Evacuation group information transmission processing]
After the evacuation group determination process described with reference to FIGS. 7 and 8, the analysis processing unit 34 and the data transmission unit 38 of the evacuation support server 30 perform predetermined processing on the mobile terminal 10 possessed by the captain of each evacuation group. An information transmission process for transmitting information is executed. Efforts to evacuate safely and accurately are provided by communicating information about the evacuation situation after the formation of each evacuation group to the captain of the evacuation group.

  FIG. 9 shows a flowchart of the evacuation group information transmission process to the captain. Information transmission regarding the evacuation group to the captain of each area will be described with reference to FIG.

  First, the analysis processing unit 34 of the evacuation support server 30 acquires the position information of the captain of each evacuation group based on the location ID of the log data (S301). In addition, information on persons in charge of each role in each area (each evacuation group) and the total number of persons are acquired (S302).

  Then, the data transmission unit 38 of the evacuation support server 30 gives the captain of each evacuation group the total number of evacuation groups to be the captain, personal IDs of persons in charge for each role, and personal IDs of other members of the evacuation group. Is transmitted to the mobile terminal 10 owned by the captain. If the evacuation guidance data is not transmitted to the captain, in this process, the meeting place is also transmitted.

  FIG. 10 is a display example of the personal ID for each role received by the data receiving unit 13 of the mobile terminal 10 owned by the captain and displayed on the display unit 14 and the personal IDs of other members of the evacuation group. As a result, the captain can quickly call the members of the evacuation group who gathered at the predetermined meeting place, and can evacuate quickly in units of this group, ensuring safety as soon as possible. it can.

  In this embodiment, an example is described in which the personal ID of the person in charge for each role and the personal ID of other members of the evacuation group are transmitted to the mobile terminal 10 owned by the captain. These may also be transmitted to members of the evacuation group.

[Evacuation route transmission processing]
The analysis processing unit 34 of the evacuation support server 30 preferably includes an evacuation route determination unit that calculates an evacuation route that can evacuate most efficiently from the meeting place of each evacuation group, and transmits the calculated evacuation route to the captain. .

  The evacuation route transmission process will be described. FIG. 11 is an explanatory view schematically showing the layout of an office building composed of a 4-story building S and a building N and position information of each evacuation group. In the example of FIG. 11, three groups of group A, group B, and group C are organized as an evacuation group. Group A is shown in 4F-S, group B is shown in 2F-S, and group C is shown in a set location in 3F-N. In this case, it is possible to evacuate quickly as a whole by transmitting an appropriate evacuation route to the captain of each evacuation group.

  FIG. 12 shows a flowchart of the evacuation route transmission process to the captain. The evacuation route transmission flow to the captain in each area will be described with reference to FIG.

  First, the analysis processing unit 34 of the evacuation support server 30 acquires the position information of the captain of each evacuation group based on the location ID of the log data (S401). Next, based on the boundary condition, a combination that minimizes the maximum time in each evacuation route is selected, and an evacuation route from each area is determined (S402).

  An example of evacuation route determination processing will be described with reference to FIG. Here, as a boundary condition, it is assumed that only 20 people / F (per floor) can exist per minute in each evacuation route, and if the condition is exceeded, a waiting time occurs on the upper floor side. In addition, the evacuation coefficient is calculated on the upper floor or on the assumption that the degree of influence increases as the number of people increases. When calculating as a combination that minimizes the maximum total sum of each evacuation route, group A and group B use the evacuation route in the southeast direction (referred to as SE) and group C uses the evacuation route in the northwest direction (referred to as NW) Can be calculated to be optimal. The evacuation route determination process only needs to be calculated based on the collection position of the evacuation group and the map information of the facility, and a known calculation method can be used.

  Then, the data transmission unit 38 of the evacuation support server 30 transmits the evacuation route calculated as the optimum route of the evacuation group serving as the captain to the captain of each evacuation group to the portable terminal 10 owned by the captain. Thus, by calculating the optimum evacuation route from the gathering position of the evacuation group and transmitting it to the captain, it is possible to evacuate quickly in the entire evacuation group.

  In this embodiment, an example in which the evacuation route is transmitted to the mobile terminal 10 owned by the captain has been described. However, the evacuation route may be transmitted to the members of the evacuation group other than the captain. good.

  As described above, in the evacuation support system 100 according to the present embodiment, the evacuation target person is grouped and assigned an appropriate role, and the evacuation can be efficiently performed in units of individual evacuation target persons. The entire evacuation target can be evacuated efficiently, and all the evacuation target can be evacuated quickly.

  Specifically, when information is transmitted when an evacuation occurs, the number of affected persons and roles as an organization are transmitted to the evacuation target person based on the position information of the evacuation target person and the personal characteristics of the evacuation target person. Therefore, it becomes possible to assume the number of people affected when each evacuated person does not fulfill their role, and it is possible to appeal to human morals. Each evacuation subject can be encouraged to act in consideration of the overall gain. As a result, the self gain is maximized, and everyone can evacuate quickly.

  The above-described embodiment is a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention.
