  Hereinafter, an embodiment using the present invention will be described. First, the system configuration of the support system 100 according to the present embodiment and the automatic fire notification facility 200 (hereinafter referred to as “self fire report”) as an abnormality alarm facility to which the support system 100 is connected will be described with reference to FIG. To do.

  The support system 100 includes a plurality of portable terminals 2 that are carried by members of a self-defense fire brigade or the like corresponding to an abnormality such as a fire, and a support device 1 connected to the receiver 4 of the self-fire report 200. The support device 1 and the mobile terminal 2 communicate with each other via the communication line 3. The communication line 3 is, for example, a wireless communication network conforming to IMT-2000, but is not limited thereto, and may be, for example, an indoor wireless LAN conforming to iIEEE802.11. The communication line 3 is a communication network that is connected to at least each mobile terminal 2 by wireless communication and performs communication between the support apparatus 1 and the mobile terminal 2.

  The self-fire report 200 is a known automatic fire alarm facility that is installed in accordance with national regulations such as the Fire Service Act (in Japan, Fire Service Act Article 17 and Fire Service Law Enforcement Ordinance Article 21). As long as the self-report 200 complies with or complies with such regulations, the self-report 200 does not necessarily have to be installed according to the above regulations, and may be self-installed. The self-fire report 200 includes a fire detector 5 and a gas leak detector 6 as sensing means for sensing abnormalities such as a fire and a gas leak. The sensing means 5 and 6 are disposed at various places of the building, and are connected to the fire receiver 4 via the signal line 10 or via the repeater 8 and the signal line 10. When an abnormal fire or gas leak is detected, a detection signal is sent to the receiver 4. The fire receiver 4 is installed in a disaster prevention center (not shown) such as a first floor portion of a building. When the fire receiver 4 determines that the fire is abnormal based on the sensing signals from the sensing means 5 and 6, the fire receiver 4 issues an alarm and sends out a fire or other abnormality signal, and is disposed in the building. An alarm sound or an alarm message is output from the acoustic device 7 or the like, and an abnormality such as the occurrence of a fire is notified.

  The sensing means 5 and 6 have addresses, which are unique identifiers assigned individually, so that when sensing abnormalities such as the occurrence of a fire, it is possible to determine which sensing means sensed. That is, the self-report 200 is a so-called addressable system, and acquires location information of occurrence of an abnormality based on the addresses of the sensing means 5 and 6 that detected the abnormality. Further, even when these sensing means 5 and 6 do not have a unique identifier such as an address, the receiver 4 may be able to determine the section where the sensing means 5 and 6 are disposed. . In this case, the position information of occurrence of the abnormality is acquired as a section where the abnormality is sensed.

  The positioning system used by the positioning unit 26 is appropriately selected according to the use environment of the support system 100 of the present invention. However, the positioning system is not limited to these, and any positioning can be used as long as it can obtain its own position information. It may be a system. And the positioning part 26 acquires the positional information on the portable terminal 2 periodically periodically using such a positioning system. Note that the location information of the mobile terminal 2 is not limited to being acquired periodically, but may be acquired in response to a request from the support device 1.

  Next, the example of the image displayed on the display screen 251 of the portable display part 25 is demonstrated about the case where a smart phone is used for the portable terminal 2. FIG. As shown in FIG. 4, the mobile terminal 2 using the smartphone occupies most of the substantially rectangular front surface with the display screen 251 of the mobile display unit 25, and a touch panel 241 is provided on the display screen 251. The display screen 251 displays an abnormality occurrence, an abnormality occurrence position, its own position, a surrounding map including these positions, and buttons for operation in cooperation with the support apparatus 1. Here, for the sake of simplicity, a display example of the display screen 251 when an abnormal fire occurs in one building will be described with reference to FIGS.

  First, a description will be given with reference to FIG. FIG. 5 is a display example when fire information is notified from the support apparatus 1 as abnormality information. A state display unit 2510 that prominently displays the display state is provided so that the user can grasp what is displayed on the display screen 251. In the case of FIG. 5, a state display portion 2510 occupying most of the width of the display screen 251 is provided at the upper end of the display screen 251, and a “fire occurrence” character indicating that a fire has occurred is displayed. A graphic display unit 2511 is provided at the center of the display screen 251 and a map based on the map information in the storage unit 22 is displayed. Here, a cross-sectional map illustrating the height direction of a three-story building as a building is displayed. Then, the symbol “x” representing the fire floor is displayed on the third floor portion based on the fire information from the support device 1 and the first floor portion based on the position information from the positioning unit 26, superimposed on the displayed cross-sectional map. The symbols “◯” representing the current location are respectively displayed on the screen. A cross-sectional map that displays only such a hierarchy cannot be displayed up to the detailed position on each floor, but if the fire floor and the current location are in a different hierarchy, both are displayed simultaneously and looked down, and the positional relationship This makes it easy to grasp the situation of the entire building. In addition, an operation button using the touch panel 241 is provided in a rectangular area representing each floor, and a detailed plan map of a desired floor according to the button of the floor operated as described later (a horizontal section is shown). To be displayed. For example, the operation area 241a of the touch panel 241 is displayed on the display area 2511a of the first floor, the operation area 241b is displayed on the display area 2511b of the second floor, and the operation area 241c is displayed on the display area 2511c of the third floor. Each is provided (not shown). A text display unit 2512 is provided at the lower end of the display screen 251 to display a legend of symbols displayed on the graphic display unit 2511 and an operation method for displaying a detailed plan view of each floor. Helps understand how to operate.

  When an operation of touching the operation area 241c of the touch panel 241 that overlaps the display area 2511c of the third floor portion that is the fire floor is performed on the cross-sectional map display screen (FIG. 5), the third floor that is the fire floor is displayed on the graphic display section 2511. The plane map 2514 is displayed, and the symbol “x” indicating the fire position is displayed over the plane map 2514. Thereby, a detailed fire position can be grasped. In addition, an operation button area 2513 for returning to the original cross-sectional map display is displayed below the flat map 2514, and when the operation area of the touch panel 241 that overlaps the operation button area 2513 is operated, the cross-sectional map display shown in FIG. Can do. At this time, the text display unit 2512 displays the legend of the symbols displayed on the graphic display unit and the operation method for returning to the display of the cross-section map, which helps to understand the display contents and the operation method (see FIG. 6). . Although not shown, when displaying a planar map, it is preferable to simultaneously display the number of floors being displayed with characters or the like. If the hierarchy of the currently displayed map is displayed in this way, it can be understood by looking at the screen 251 even if the displayed floor is likely to be forgotten.

  Further, when an operation of touching the operation area 241a of the touch panel 241 that overlaps the display area 2511a of the first floor portion that is the current location is performed on the cross-sectional map display screen (FIG. 5), the first floor that is the floor of the current location is displayed on the graphic display unit 2511. A flat map 2515 is displayed, and a symbol “◯” indicating the current location is displayed over the flat map 2515. This makes it possible to grasp the detailed current location. In addition, an operation button area 2513 for returning to the original cross-sectional map display is displayed below the flat map 2515, and when the operation area of the touch panel 241 that overlaps the operation button area 2513 is operated, the cross-sectional map display shown in FIG. Can do. At this time, the text display unit 2512 displays the legend of the symbols displayed on the graphic display unit and the operation method for returning to the display of the cross-sectional map, and helps to understand the display contents and the operation method (see FIG. 7). .

On the other hand, when the mobile terminal 2 determines that the fire floor and the current location are the same floor, the mobile terminal 2 may display the common floor plan map without displaying the cross-sectional map shown in FIG. Good (see FIG. 8). Even in such a case, the fire may not spread to other floors, or a simultaneous fire may not occur on other floors. Therefore, it is desirable to be able to display the cross-sectional map as shown in FIG. 5 so that the state of the entire building can be grasped. That is, similarly to the planar map display of FIGS. 6 and 7, an operation button area 2513 for returning to the original sectional map display is displayed below the planar map 2515. And if the operation area of the touch panel 241 which overlaps this is operated, it can return to the cross-section map display shown in FIG.
In addition, when displaying a planar map like FIG. 6 thru | or FIG. 8, it is preferable to display simultaneously the number of floors currently displayed with a character etc. FIG. If the hierarchy of the currently displayed map is displayed in this way, it can be understood by looking at the screen 251 even if the displayed floor is likely to be forgotten. Further, the display of the planar map may be map information enlarged in four divisions, etc., and the positional relationship is also shown, and it is preferable that the selection operation can be performed and the display can be arbitrarily displayed.

  Next, the operation of the support system 100 will be described. First, operation | movement of the assistance apparatus 1 is demonstrated based on FIG. 2 and FIG. 11 thru | or FIG.

  The control unit 11 of the support apparatus 1 waits for abnormality information from the receiver 4 via the first communication unit 13 (S101). This abnormality information includes an identifier unique to the sensing means 5 and 6 that senses the abnormality, identifies the position of the abnormality, or section information where the sensing means 5 and 6 that sense the abnormality are installed, and abnormal contents. Yes. Then, the control unit 11 waits for the abnormality information from the receiver 4 until the abnormality information from the receiver 4 is received (No in S101), and determines that the abnormality has occurred when the abnormality information from the receiver 4 is received. The process proceeds to step S102 (Yes in S101).

  Next, the specifying unit 111 specifies the content of the abnormality based on the received abnormality information, acquires the installation location of the sensing means 5 and 6 that detected the abnormality with reference to the map database 121 as the abnormality position information, Identify the location. Then, the display control unit 115 displays the abnormal position and the abnormal content on the display unit 15 together with the peripheral map information including the abnormal position acquired from the map database 121 (S102). On the display unit 15, either the cross-sectional map as shown in FIG. 5 or the planar map as shown in FIG. 6 is appropriately selected and displayed. And the request | requirement part 112 acquires the identifier of the portable terminal 2 which comprises the assistance system 100 with reference to the terminal beta base 122, and with respect to each portable terminal 2 which has the said identifier via the 2nd communication part 14. A request is made to transmit the position information possessed by each portable terminal (S103). At this time, the abnormal information may be transmitted to the mobile terminal 2 so that the mobile terminal 2 displays the abnormal position and the abnormal content.

  Next, the reception unit 113 determines the presence / absence of position information of the mobile terminal transmitted from the mobile terminal 2 via the second communication unit 14 (S104). The reception unit 113 proceeds to the next step S105 when the position information transmitted from the portable terminal 2 is received (Yes in S104), and the step described later when the position information transmitted from the portable terminal 2 is not received. It progresses to S108 (No of S104).

  Based on the position information of the portable terminal 2 received by the reception unit 113 from the portable terminal 2, the display control unit 115 displays the position of the portable terminal 2 on the map information and abnormality information displayed on the display unit 15 (S105). ). At this time, if the coordinate system of the position information of the mobile terminal 2 is different from the map information and the abnormality information, the coordinate information may be converted into coordinate information corresponding to the display unit 15 via the coordinate conversion unit 116 described later. The display control unit 115 displays the converted position of the mobile terminal 2 on the map information and abnormality information displayed on the display unit 15 (not shown).

The display unit 15 displays, for example, an abnormal position on a map displayed on the screen of the display unit 15 with a predetermined symbol representing the abnormal content, and the position of each mobile terminal 2 is displayed by the member carrying the mobile terminal 2. A predetermined symbol is also displayed as a position. And the notification part 114 transmits abnormality information with respect to the portable terminal 2 which transmitted position information, and displays the unusual position and abnormal content on the portable terminal 2 (S106). At this time, the position information of the portable terminal 2 that has transmitted the position information may be notified to the other portable terminal 2 and displayed together with the portable terminal 2 that has received this notification.
And it is determined whether the positional information from all the portable terminals 2 registered into the terminal database 122 was received (S107). If it is determined that the location information from all the mobile terminals 2 registered in the terminal database 122 has been received, the process proceeds to step S109 (Yes in S107), and if it is determined that the position information has not been received, the next step Go to S108 (No in S107).

  By the way, the position information of the mobile terminal 2 is not always transmitted from all the mobile terminals 2 that have requested to transmit the position information. This is because the terminal 2 is located in a place where radio waves do not reach, the mobile terminal 2 is not turned on, or the mobile terminal 2 is out of order. It is necessary to perform timeout processing in order to avoid this. Therefore, a timeout time that is a predetermined time from the position information transmission request to the mobile terminal 2 is determined in advance. If the elapsed time from the request to the mobile terminal 2 is less than the timeout time, the process returns to step S104 to continue the reception operation of the position information transmitted from the mobile terminal 2 (No in S108). When the time from the transmission request to the portable terminal 2 has passed the timeout period, the reception of the position information transmitted from the portable terminal 2 is terminated and the process proceeds to the next step S109 (FIG. 12) (Yes in S108). Before proceeding to the next step S109, the mobile terminal 2 is notified of the position information of all the mobile terminals 2 that have been transmitted to all the mobile terminals 2 that have transmitted the position information. It is good (not shown).

  After step S109, processing is performed by determining whether or not new abnormality information is generated (so-called subsequent abnormality notification) and whether or not a recovery operation is performed (FIG. 12), and the position of the portable terminal 2 is displayed in real time. It is an operation | movement flow which performs a process (FIG. 13). First, it is determined whether or not the control unit 11 has received new abnormality information from the receiver 4 via the first communication unit 13 (S109). At this time, if new abnormality information has not been received, it is determined that no new abnormality has occurred, and the process proceeds to step S112 (No in S109). At this time, if new abnormality information has been received, it is determined that a new abnormality has occurred, and the process proceeds to the next step S110 (Yes in S109). When it is determined that a new abnormality has occurred, the position information of the mobile terminal 2 received by the receiving unit 113 from the terminal 2 is converted into the coordinates corresponding to the display unit 15 via the coordinate conversion unit 116, as in step S105. Convert coordinates to information. Then, the display control unit 115 displays the converted position of the portable terminal 2 on the map information and the abnormality information displayed on the display unit 15 (S110). Then, as in step S106, the notification unit 114 transmits new abnormality information (subsequent abnormality notification information) to the mobile terminal 2 that has transmitted the position information, and notifies the mobile terminal 2 of the abnormal position and the abnormal content. (S111), the process proceeds to the next step S112.

  Next, it is determined whether or not there is a recovery operation (S112). Here, the recovery operation is to restore the receiver 4 when an abnormality such as a fire has converged or when the abnormality information itself is caused by a factor other than an abnormality such as a fire (for example, a so-called non-fire report). It is a series of operations to converge the situation such as operation. The support device 1 may receive a recovery signal indicating that the recovery operation has been performed by the receiver 4 via the first communication unit 13. Alternatively, the control unit 11 may receive a recovery operation in the operation unit 16 of the support device 1. When none of these recovery operations is received by the control unit 11, it is determined that there is no recovery operation, and the process proceeds to step S115 (No in S112). Conversely, when the control unit 11 receives at least one of these recovery operations, it proceeds to the next step S113 after determining that the recovery operation has been performed.

  If it is determined that the restoration operation has been performed, the control unit 11 resets the display on the display unit 15 via the display control unit 115 to return to the normal state (S113). Further, the control unit 11 transmits all the mobile terminals 2 registered in the terminal database 122 or all the mobile terminals 2 that have transmitted the location information via the notification unit 114 and the second control unit 14. The fire recovery information is notified (S114). In other words, the convergence of the situation is notified, a series of operations of the support system is made to converge, and the activities of the personnel accompanying it are converged (end of FIG. 12).

  On the other hand, when it is determined that the restoration operation has not been performed, the request unit 112 requests each mobile terminal 2 to retransmit the position information possessed by each terminal as in step S103 (S115). At this time, the notification unit 114 may retransmit the abnormal information to the mobile terminal 2 so that the mobile terminal 2 can confirm or redisplay the abnormal position and the abnormal content. Next, as in step S104, the reception unit 113 determines the presence / absence of the location information of the terminal transmitted from the mobile terminal 2 via the second communication unit 14 (S116). If the position information transmitted from the mobile terminal 2 is not received, the reception unit 113 proceeds to step S119 described later (No in S116), and if the position information transmitted from the mobile terminal 2 is received, the next step It progresses to S117 (Yes of S116). The position information of the mobile terminal 2 received by the reception unit 113 from the mobile terminal 2 is coordinate-converted to coordinate information corresponding to the display unit 15 via the coordinate conversion unit 116, and the display control unit 115 converts the converted mobile terminal 2. The position is displayed on the display unit 15 (S117), and the process proceeds to the next step S118. At this time, the notification unit 114 may retransmit the abnormality information to the terminal 2 so that the portable terminal 2 can confirm or redisplay the abnormality position and the abnormality content. Then, similarly to step S107, it is determined whether or not position information from all the mobile terminals 2 registered in the terminal database 122 has been received (S118). And when it determines with having received the positional information from all the portable terminals 2 registered into the terminal database 122, it goes to step S109 (Yes of S118), and when it determines with not having received, it is the next step. Go to S119 (No in S118). Then, similarly to step S108, when the elapsed time from the transmission request to the portable terminal 2 is less than the timeout time, the process returns to step S116 and continues the reception operation of the position information transmitted from the portable terminal 2 (No in S119). ). When the timeout period has elapsed since the occurrence of the abnormality, the reception of the position information transmitted from the mobile terminal 2 is terminated and the process proceeds to step S109 (FIG. 12) (Yes in S119).

  Next, operation | movement of the some portable terminal 2 which comprises the assistance system 100 is demonstrated based on FIG.

  Each mobile terminal 2 uses the positioning system, and the positioning unit 26 acquires terminal position information that is its own position information (S201). When there is a terminal location information transmission request from the support apparatus 1, the terminal location information may be acquired in step S203 described later. The acquired terminal position information is stored in the storage unit 22 and is maintained until the next terminal position information is acquired and updated. Next, it is determined whether a terminal location information transmission request from the support apparatus 1 has been received via the communication unit 23 (S202). If it is determined that the terminal location information transmission request from the support apparatus 1 has not been received, the process proceeds to step S204 described later (No in S202).

At this time, as described above, after the terminal position information is acquired by the positioning unit 26, a terminal identifier may be attached to the acquired terminal position information and transmitted to the support apparatus 1.

  Next, it is determined whether or not the abnormality information transmitted from the support device 1 is received via the communication unit 23 (S204). If it is determined that the abnormality information from the support device 1 has not been received, the process proceeds to step S206 described later (No in S204). When it determines with having received the abnormality information from the assistance apparatus 1, it progresses to the following step S205 (Yes of S204). Then, based on the abnormality information received from the map information stored in the storage unit 22, the map information for displaying the map on the screen 251 of the portable display unit 25 is read, and the abnormality content and the abnormality position based on the received abnormality information are read out. And the terminal position based on the own position information acquired by the positioning unit 26 is displayed on the screen 251 (S205). At this time, a map based on the read map information is displayed on the screen 251, and the abnormal position and the terminal position are displayed so as to overlap the map.

  Then, the terminal position information is read from the storage unit 22 and the position of the terminal is displayed so as to be superimposed on the map displayed on the screen 251 (see FIGS. 5 and 8). At this time, when the terminal position and the abnormal position are located on the same floor, the terminal is displayed on a plan view as shown in FIG. 8, and when the terminal position and the abnormal position are located on different floors, You may make it display on a cross-sectional map as shown in FIG. As described above, when the abnormal position and the terminal position of the terminal are displayed at the same time, the positional relationship can be looked down on. Further, if the cross-sectional map is switched to the plane map of an arbitrary floor (see FIG. 5), there is an effect that a detailed planar position can be grasped. In addition, if the plane map is arbitrarily switched to the cross-sectional map, both the positional relationship and the detailed planar position can be easily grasped (see FIGS. 6 to 8).

  In step S204, it may be determined whether or not the position information of the other portable terminal 2 has been received from the support apparatus 1.
