Disaster information is stored. Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram illustrating a system configuration according to an embodiment of the present invention. First, an evacuation guidance message transmission sequence on the facility management system side when a disaster occurs in a building will be described with reference to FIG. When a disaster occurs in the facility, first, sensors / monitoring devices (34A to 34A) connected to the management system
F) detects the occurrence of a disaster (P1). The detected disaster information is transmitted (P2) to the control device 32 in the facility management system 3 via the sensor interface (31).
The control device 32 that has received the disaster information notifies the private branch exchange 2 of the disaster information via the external interface 33 (P3). However, when the number of pedestrians detected by the human sensor 34F exceeds a certain value preset in the control device 32, it is determined that a disaster has occurred and the private branch exchange 2 is notified (P3). Next, a processing sequence on the private branch exchange side that has received the disaster information notified from the facility management system will be described with reference to FIG. The private branch exchange 2 notified of the disaster information from the external interface 22 first checks whether disaster information has been sent (Q1). If there is information, the received disaster information is stored in the memory 26 (Q2), and the disaster information and the area information obtained by the area recognizing unit 24 are integrated by the central processing unit 21 to obtain the disaster occurrence location. And identify the situation of the disaster. The information such as the disaster occurrence location obtained here is stored in the memory 26 (Q
3) Yes. The central processing unit 21 searches for an optimal evacuation route for each area using the evacuation route selection data 23B stored in the database unit 23 based on the information on the disaster occurrence location and the like obtained here, and stores the result in a memory. 26 (Q
4) After that, restrict incoming and outgoing calls to various terminals (Q
5). An appropriate message is selected from the evacuation guidance messages stored in the message storage unit 23A of the database unit 23 based on the area information which is the content of the stored memory 26 and the evacuation route number, and the selected message is The disaster situation stored in the memory 26 is
The signal is transmitted to the fixed installation terminal 4 and the base station 5 in each area via the control unit 25 (Q6) (Q7).
As a result, optimal evacuation guidance information according to the area is transmitted to evacuees in the area of the corresponding base station 5. At this time, the call is forcibly disconnected and the evacuation guidance information is transmitted to the busy terminal. Further, the disconnected call can be re-established as necessary, so that it is possible to prevent a necessary call from being disconnected carelessly. Next, an evacuation guidance message transmission sequence when an evacuee starts moving based on the evacuation guidance message obtained in the previous term and moves in an area is shown in FIGS.
This will be described with reference to FIG. As shown in FIG. 2, the area within the facility is divided into AR1 to AR15, where AR15 is an evacuation site with a facility exit, and AR1 is a location where an evacuee (USR), which is the deepest part of the facility, is currently located. is there. The following description is based on the assumption that an evacuation route is set as shown in the figure. Evacuees (USR) in area AR1
The evacuation is started based on the evacuation guidance information due to the occurrence of the disaster, and moves to the area AR2. At this time, the private branch exchange detects that the location registration has been performed by the mobile terminal moving to the base station area. Accordingly, the central processing unit 21 connected to the private branch exchange 2 recognizes that the refugee (USR) has moved to the AR2 (R1), and at the same time, stores the area information of the refugee and the evacuation status in the personal data storage unit. After saving (R2)
The evacuation route number corresponding to AR2 is searched from the memory 26 (R3). From the evacuation route number and the area number AR2 obtained here, an appropriate message in the evacuation guidance message stored in the message storage unit 23A of the database unit 23 is selected (R4), and the selected message and memory are selected. The disaster situation stored in 26
The information is transmitted to the refugee (USR) via the control unit 25 and the base station 5 (R5, R6). This allows evacuees (US
R), even during guidance by the evacuation guidance message,
An appropriate evacuation guidance message for going to the next area AR3 which is an evacuation route can be obtained. Next, with reference to FIGS. 3, 4, 5, 5, 7, 8, and 10, the evacuation route is selected when a secondary disaster occurs during the evacuation of the evacuee by receiving the evacuation guidance message.
This will be described with reference to FIG. When no disaster has occurred, the evacuees are in AR1. Here, it is assumed that a primary disaster has occurred in AR9 by the disaster detection unit. In this case, as described above, the area AR9, which is the location of occurrence, and the disaster information are stored in the primary disaster area of the memory of FIG. 8 (Q2, Q3). Next, an evacuation route is selected in the AR1 where evacuees are present, based on evacuation route selection data (FIG. 4). First, the area AR1 where the evacuees are located in the route 1 is searched. A
R1 is position 6 (deepest part), so position 0 (facility exit)
Search again for the disaster area AR9 in the route to.
If evacuation route 1 is selected from area AR1 where evacuees are located, area AR1 will not pass through disaster area AR9.
Evacuation route is determined as “Route 1” and the result is stored in Memory 2
6 (Q4). As a result, the message to be sent to the evacuees in the area AR1 is "MSG11", which is the message for route 1, and transmitted to the evacuees. Similarly, the routes of AR2 and AR3 are also “route 1”, and the messages are respectively “MSG”.
12 "and" MSG13 "are selected. Next, the evacuees use the evacuation guidance message to
Assume that a secondary disaster occurs in AR4 when the vehicle reaches R2. In this case, similarly to the above, AR4, which is the occurrence location, and disaster information are stored in the secondary disaster area of the memory shown in FIG. 8 (Q2, Q3). Next there is an evacuee A
Evacuation route selection at R2 is performed based on evacuation route selection data (FIG. 4). First, the area AR2 where the evacuees are located in the route 1 is searched. Since AR2 is at position 5, the disaster area 33 is located on the route to position 0 (facility exit).
And 34D are searched. Since the disaster area 4 exists on the route 1, the use of the route 1 is stopped, and the process proceeds to the search process on the next route. Next, a similar search is performed in route 2.
Also in this case, since the disaster area 33 exists on the route 2, the use of the route 2 is stopped, and the process shifts to the search process on the next route. This time, a similar search is performed on route 3. Route 3
Since no disaster area is detected above, “escape route” is determined as “route 3” and the result is stored (Q4) in the memory (FIG. 7). As a result, as the message sent to the evacuees in the area AR2, "MSG32", which is a message for route 3, is selected and transmitted to the evacuees. Similarly, the routes of AR1 and AR3 also become “route 3”, and “MSG31” and “MSG33” are selected as the messages, respectively. Next, an evacuation status notification when an evacuee wants to know the evacuation status of another person during or after evacuation or when a person outside the building (family, etc.) wants to know the evacuation status of a person inside the building. The processing sequence will be described with reference to FIGS. First, when a terminal call event occurs, it is determined whether a disaster is occurring as shown in FIG. 12 (S1). If no disaster has occurred, the callee is connected as usual (S
6). If a disaster has occurred here, the terminal type is determined (S2). At this time, if the calling terminal is a fixed terminal, the caller is notified that a connection cannot be established due to a disaster (S5). Next, when the calling terminal is a mobile terminal, the information of the terminal is searched from the personal data shown in FIG. 6 (S3), and "NAM1 is currently
We are evacuating the R5 area. "
The evacuation to the area is completed "is notified to the sender (S4). As described above, when a disaster such as a fire or an earthquake occurs in the facility, the evacuees provide appropriate guidance information on the disaster conditions and evacuation routes that constantly change during the evacuation of the evacuees. Each evacuee can check the evacuation information on their own terminal because it can be obtained repeatedly according to the location information, thereby preventing a panic situation caused by anxiety due to lack of information beforehand and evacuation guidance information to the mobile terminal In addition to the transmission, by displaying an evacuation guidance message on the display unit without ringing to the fixed installation terminals located in each area, fixed installations where evacuees who do not have mobile terminals can move Evacuation guidance information similar to that of a person with a mobile terminal can be obtained by looking at the terminal, allowing all persons inside the building to reach the final evacuation site It is possible to provide a Do evacuation guidance system. In addition, since it is possible to provide information on the evacuation status of people inside the building to people inside and outside the building, there is a means to confirm the safety of others.
It is possible to remove the mental anxiety that you do not know the safety of friends / acquaintances. As described above, the first effect of the present invention is to provide evacuation guidance information suitable for the position of an evacuee at the time of a disaster, thereby enabling the evacuee to be in a disaster situation. Can be correctly grasped and appropriate evacuation behavior can be taken. The second effect is that if a second disaster occurs on the evacuation route provided by the evacuation guidance information during the evacuation of the evacuee based on the information provided by the first effect, Appropriate evacuation guidance information bypassing the secondary disaster location can be provided again together with information on the occurrence of the secondary disaster. The third effect is that, along with the first and second effects, appropriate evacuation information is constantly provided even while the evacuees are moving, so that the evacuees can safely and safely reach the evacuation site. It is possible to reach quickly. The fourth effect is that, by detecting the transition state of the evacuees and providing appropriate guidance information, the evacuees can be dispersed and guided without being concentrated at one place. . The fifth effect is that, along with the third effect and the fourth effect, since information that can safely and quickly reach the evacuation site is provided, anxiety due to lack of information at the time of disaster is provided.
Also, it is possible to prevent a panic state due to emotions such as prostration caused by traffic congestion due to concentration at one place. A sixth effect is that congestion of the exchange can be prevented by restricting incoming and outgoing calls in the event of a disaster. A seventh effect is that a call during a call is forcibly disconnected when a disaster occurs, so that a person who is talking can be notified of a disaster situation. The eighth effect is that the evacuees who are moving during evacuation and who have completed evacuation want to know if others (friends / acquaintances) are evacuating, can check the evacuation status of others. It becomes possible. The ninth effect is that, when a disaster occurs, a person outside the building can check the evacuation status of a person (family or the like) inside the building.
