For example, "1" for the IP camera 7 on the fire floor, "2" for the IP camera 7 on the immediate upper floor, "3" for the IP camera 7 on the direct floor, and "3" for the IP camera 7 on the other floors. Each "4" is associated with the address of the IP camera 7 and stored in the equipment database 242. The urgency information regarding the IP camera 7 can be used for the residual person detection in the second residual determination unit 257, which will be described later.

Further, the fire alarm unit 253 transmits a terminal position information transmission request to the support server 4 via the information transmission unit 255 and the communication unit 21 based on the fire information received by the information reception unit 251. The terminal position information transmitted from the support server 4 based on this transmission request is received by the information reception unit 251 via the communication unit 21. The fire alarm unit 253 refers to the equipment database 242 based on the terminal position information received by the information reception unit 251 to identify the section and floor located for each terminal 5, and further, relative to the fire floor. Identify the positional relationship. Then, the information on the relative positional relationship with the specified fire floor is associated with the terminal ID of the terminal 5 and transmitted to the support server 4 via the information transmission unit 255 and the communication unit 21. The relative positional relationship with the fire floor is information indicating the high degree of urgency to take evacuation or the like in response to a fire. The urgent floor is a floor relatively close to the fire floor, specifically, at least the fire floor, which may include one or both of the floors directly above and below. As for the information on the relative positional relationship with the fire floor, the support server 4 notifies the terminal 5 of an alarm message expressed by the relative positional relationship with the fire floor (more specifically, the positional relationship in the vertical direction). It is used for.

At this time, the fire alarm unit 253 may store information indicating the height of urgency based on the relative positional relationship with the specified fire floor in the equipment database 242 in association with the terminal ID of the terminal 5. .. For example, "1" for the terminal 5 on the fire floor, "2" for the terminal 5 on the immediate upper floor, "3" for the terminal 5 on the immediate lower floor, and "4" for the terminal 5 on the other floors. , Each of which is associated with the terminal ID of the terminal 5 and stored in the equipment database 242. The transmission of the urgency associated with the terminal ID to the support server 4 may be executed with reference to the urgency stored in the equipment database 242.

Further, when the information receiving unit 251 receives the terminal device operation information, the fire alarm unit 253 refers to the equipment database 242 based on the address of the fire prevention / smoke prevention device S included in the terminal device operation information, and refers to the equipment database 242, and the type of the device. Determines whether or not is the fire protection shutter S'. When the type of the device is the fire protection shutter S', the address of the speaker 6 with a microphone arranged in the vicinity of the fire protection shutter S'is specified. Then, the control information for outputting a warning message notifying that the fire protection shutter S'is in the closing operation from the speaker 6 with a microphone at the specified address by voice is output to the information transmission unit 255 in association with the address. Here, the speaker 6 with a microphone arranged in the vicinity of the fire protection shutter S'is a speaker 6 with a microphone arranged and associated with the fire protection shutter S'on the same floor, and is, for example, the fire protection shutter. The speaker 6 with a microphone closest to S'. When the information receiving unit 251 receives the terminal device operation confirmation information regarding the fire prevention shutter S', it outputs the control information for stopping the output of the warning message.

When the above warning message is output, if the speaker with a microphone at the address is associated with the relative positional relationship with the fire floor, the control for broadcasting a fire from the speaker with a microphone 6 by temporarily canceling this is performed. The information is stopped, and the control information for outputting the above warning message by voice is output. Then, when the information receiving unit 251 receives the terminal device operation confirmation information regarding the fire prevention shutter S', it outputs the control information for stopping the output of the warning message, and then the control information associated with the relative positional relationship with the fire floor. Is output, and the fire broadcast may be output from the speaker with a microphone.

The voice output control unit 254 causes the speaker 26 to output voice based on the voice signal received by the information reception unit 251.

The information transmission unit 255 transmits the control information from the fire alarm unit 253 to the emergency broadcasting equipment 3 via the communication unit 21. Further, the information transmission unit 255 transmits the urgency information for each terminal ID from the fire alarm unit 253 to the support server 4 via the communication unit 21.

Further, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual person by the operator after starting the fire broadcasting, a call message calling to the residual person remaining in the building is sent to each floor of the building. The control information for sequentially outputting audio from the arranged speaker 6 with a microphone is transmitted to the emergency broadcasting equipment 3 via the communication unit 21. At that time, the call message is output by voice in order from the floor with the highest urgency among the multiple floors of the building. Here, the order of highest urgency is, in other words, the order closer to the place where the fire occurred. The urgency of the upper floors is high between floors that have the same vertical distance from the place where the fire broke out. For example, among the fire floor, the floor directly above, and the floor directly below, the fire floor is more urgent than the floor directly above, and the floor directly above is more urgent than the floor directly below. The information transmission unit 255 identifies the addresses of the speakers 6 with microphones in descending order of urgency, and sequentially transmits control information for outputting a call message by voice. The order of floors with high urgency can be determined based on the relative positional relationship with the fire floor for each speaker with a microphone 6 already specified by the fire alarm unit 253. Based on the reaction of the residual person to this call message, the first residual determination unit 256, which will be described later, determines the existence of the residual person. It should be noted that the call message may be output from all the speakers with microphones 6 at the same time, and the first residual determination unit 256 may determine the existence of the residual person in order from the floor with the highest urgency. Further, the information transmission unit 255 does not perform the above operation by the operator, but after the predetermined time has elapsed after starting the fire broadcast based on the fire information received by the information reception unit 251, the information transmission unit 255 transmits the above control information for detecting the residual. It may be transmitted to the emergency broadcasting equipment 3.

Further, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual residue by the operator after starting the fire broadcasting, it serves as control information for determining the presence or absence of the residual residue in the building. The imaging request is transmitted to the IP camera 7 via the communication unit 21. At that time, as in the case of the call message, the IP camera 7 is requested to take an image in order from the most urgent floor among the plurality of floors of the building. The image (still image or moving image) captured by the IP camera 7 is received by the information receiving unit 251 and the second residual determination unit 257, which will be described later, determines the presence of a residual person. It should be noted that the imaging request may be made to all the IP cameras 7 at the same time, and the second residual determination unit 257 may determine the existence of the residuals in order from the floor with the highest urgency. Further, the information transmission unit 255 does not perform the above operation by the operator, but after the predetermined time has elapsed after starting the fire broadcasting based on the fire information received by the information reception unit 251, the information transmission unit 255 transmits the above control information for detecting the residual. It may be transmitted to the IP camera 7.

Further, in normal times when a fire does not occur, the information transmission unit 255 sends an imaging request as control information for determining the presence or absence of a resident in the building to the IP camera 7 via the communication unit 21. You may send it. The image (still image or moving image) captured by the IP camera 7 is received by the information receiving unit 251 and the second residual determination unit 257, which will be described later, determines the presence of a resident. The imaging request may be made to all the IP cameras 7 at the same time, and the second residual determination unit 257 may sequentially determine the existence of the resident, or the individual IP cameras 7 may be requested to take an image. Imaging requests may be transmitted in sequence. The second residual determination unit 257, which will be described later, determines at least the presence or absence of a resident in each section. At that time, the second residual determination unit 257 may determine the number of people in the building for each section. The detected resident information is stored in the residual person database 243 as resident information in normal times and can be used for checking the evacuation status in the event of a fire, especially when the number of resident is stored. It can be used to calculate the evacuation rate.

Further, in normal times when a fire does not occur, the information transmission unit 255 may periodically transmit a terminal position information transmission request to the support server 4 via the information transmission unit 255 and the communication unit 21. The terminal position information transmitted from the support server 4 based on this transmission request is received by the information reception unit 251 via the communication unit 21. Based on the terminal position information received by the information receiving unit 251, the third residual determination unit 258, which will be described later, determines at least the presence or absence of a resident in each section. At that time, the third residual determination unit 258 refers to the map information database 241 based on the received terminal position information, determines at least the presence or absence of a terminal for each section, that is, the presence or absence of a resident, and further, for each section. The number of terminals, that is, the number of people in the museum may be determined. The detected resident information is stored in the residual person database 243 as resident information in normal times and can be used for checking the evacuation status in the event of a fire, especially when the number of resident is stored. It can be used to calculate the evacuation rate.

In addition, the information transmission unit 255 transmits a transmission request for terminal position information from the fire alarm unit 253 to the support server 4 via the communication unit 21. Further, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual residue by the operator after starting the fire broadcasting, it serves as control information for determining the presence or absence of the residual residue in the building. The transmission request of the terminal position information is transmitted to the support server 4 via the communication unit 21. The terminal position information from the support server 4 is received by the information receiving unit 251 and the third residual determination unit 258, which will be described later, determines the existence of the residual person. In addition, the information transmission unit 255 does not perform the above operation by the operator, and after a predetermined time has elapsed from the start of the fire broadcast based on the fire information received by the information reception unit 251, the terminal position information for detecting the residual person is used. The transmission request may be transmitted to the support server 4.

Further, since the information transmission unit 255 makes a call by the operator using the predetermined speaker with a microphone 6, when the operation of the operation unit 23 for selecting the speaker with a microphone 6 by the operator is detected, the call is made with the selected speaker 6 with a microphone. A call request as control information is transmitted to the emergency broadcasting equipment 3 via the communication unit 21. For example, when the operator selects the speaker button Sn (n = 1, 2, 3, ...) Described later on the map screen displayed on the display unit 22, the selected speaker button Sn (n = 1, 2, 3, ...) Refers to the equipment database 242. The address of the speaker 6 with a microphone corresponding to the above is specified, and a call request including the specified address is transmitted. When a call line with the speaker with a microphone 6 selected via the emergency broadcasting equipment 3 is established based on this call request, the audio output control unit 254 receives the speaker with a microphone received by the information reception unit 251. Audio is output from the speaker 26 based on the audio signal from 6. Further, the information transmission unit 255 transmits the operator's voice signal input to the microphone 27 to the microphone-equipped speaker 6 to output the voice. In this way, the operator can talk to the survivor through the selected speaker with microphone 6.

Further, since the information transmission unit 255 displays the camera image from the predetermined IP camera 7 on the display unit 22, when the operation of the operation unit 23 for selecting the IP camera 7 by the operator is detected, the information transmission unit 255 is displayed on the selected IP camera 7. An imaging request as control information requesting imaging is transmitted to the IP camera 7 via the communication unit 21. For example, when the operator selects the camera button Cm (m = 1, 2, 3, ...) Described later on the map screen displayed on the display unit 22, the selected camera button Cm is referred to by referring to the equipment database 242. The address of the IP camera 7 corresponding to the above is specified, and an imaging request including the specified address is transmitted. When the information receiving unit 251 receives the image signal from the IP camera 7 based on this imaging request, the display control unit 252 displays the camera image on the display unit 22. In this way, the operator can select an arbitrary IP camera 7 and display the camera image on the display unit 22, so that it is possible to grasp the situation of the fire, the presence or absence of residuals, and the state thereof.

The first residual determination unit 256 is an example of the “residual determination unit” according to the present invention, and is a sound (voice or noise) picked up by a microphone arranged in the vicinity of the speaker from which the call message is output by voice. At least the presence or absence of a residue is determined based on. The speaker and the microphone are provided in the speaker with a microphone 6 in this embodiment. Here, the microphone arranged in the vicinity of the speaker is a microphone arranged at least on the same floor as the speaker that outputs the call message and is associated with the speaker, and is, for example, the closest to the speaker. Mike. The first residual determination unit 256 may determine at least the presence or absence of residuals by using a well-known or known voice analysis technique, and further determine the number of residuals.

The second residual determination unit 257 determines at least the presence or absence of residuals based on the image (still image or moving image) captured by the IP camera 7 that has received the imaging request. At that time, the second residual determination unit 257 may determine at least the presence or absence of residuals by using a well-known or known image analysis technique, and further determine the number of residuals (for example, Japanese Patent Application Laid-Open No. 2012-113367). See Gazette).

The third residual determination unit 258 determines at least the presence or absence of a residual person based on the terminal position information transmitted from the support server 4 that has received the terminal position information transmission request. At that time, the third residual determination unit 258 refers to the equipment database 242 based on the terminal position information from the support server 4 received by the information reception unit 251 and at least determines the presence or absence of terminals for each section, that is, the presence or absence of the residual person. The presence or absence may be determined, and the number of terminals in each section, that is, the number of survivors may be determined.

After the fire information is received by the information receiving unit 251, the residual information presenting unit 259 is the first residual information detected by the first residual determination unit 256 and the second residual information detected by the second residual determination unit 257. The residual information of the above and the third residual information detected by the third residual determination unit 258 are stored in the residual database 243 in association with the section of the building. Then, with reference to the residual person information stored in the residual person database 243, the residual person information for each section is displayed by superimposing it on the map screen displayed on the display unit 22.

The residual information stored in the residual database 243 by the residual information presenting unit 259 indicates at least the presence or absence of residuals in each section. The residual person database 243 may store the first to third residual person information separately, or may be the residual person information based on the calculation result of the first to third residual person information. For example, the logical sum of the first to third residual information may be taken and stored as the residual information indicating the presence or absence of the residual, and the omission of detection of the residual by each residual detection principle may be reduced. .. For example, if there is a residual person who cannot speak, the second residual determination unit 257 can detect it based on the IP camera 7 that can image the section of the residual person even if the first residual determination unit 256 cannot detect it. Further, if the residual person is in the blind spot of the IP camera 7 due to falling behind the furniture, even if the second residual determination unit 257 cannot detect the residual person, if the residual person carries the terminal 5. The third residual determination unit 258 can detect it. In this way, based on the residual detection results by the plurality of methods, it is possible to supplement the detection omission by the detection principle of each method and improve the detection accuracy of the residual.

Further, the residual information stored in the residual database 243 by the residual information presenting unit 259 may be the number of residuals for each section. In addition, in normal times before the fire breaks out, the presence / absence and the number of resident persons existing in each section may be further stored by using the residual person information determined for each section as the resident information. Then, by comparing the presence or absence of a residual person in each section with the presence or absence of a resident in the same section in normal times, it can be used for confirming the evacuation status. In addition, by dividing the number of people remaining in each section from the number of people in the same section in normal times by the number of people in the same section in normal times, each section It is possible to calculate the evacuation rate, which indicates the evacuation status of.

In order to detect the number of residual persons, the first residual determination unit 256, for example, distinguishes the residual persons who utter by detecting different voiceprints from the voice information received by the information reception unit 251 and detects the number of residual persons. can do. Further, for example, by comparing with the voice information from another speaker with a microphone 6 installed in the same section, the position where the residual person utters is distinguished based on the intensity difference, the phase difference, etc., and the number is detected. The number of survivors may be detected. Further, for example, the call message includes a message asking the number of survivors, and the survivors are requested to report the number of survivors in the section. Then, the feature amount is extracted from the voice information of the residual person received by the information reception unit 251. Here, the feature amount is a numerical value indicating the physical feature of specific voice information such as MFCC and LPC. Then, when compared with the feature quantities of "person" and "name", which are unique keywords as a unit indicating the number of people, and the degree of similarity exceeds a predetermined threshold value, a message from the survivor The number of people included in can be detected by voice recognition. This voice recognition may be executed by the first residual determination unit 256 itself, or may be executed via a voice recognition server (not shown) connected via the communication unit 21. Furthermore, other well-known or known techniques may be used to detect the number of residuals. Further, the second residual determination unit 257 can detect the number of residual persons by using a well-known or known image analysis technique for the camera image received by the information receiving unit 251 (for example, Japanese Patent Application Laid-Open No. 2012-113367). See Gazette). Further, the third residual determination unit 258 detects the number of terminals existing in each section, that is, the number of remaining persons carrying the terminal 5 in each section, based on the terminal position information received by the information receiving unit 251. Can be done.

In this way, the first residual determination unit 256, the second residual determination unit 257, and the third residual determination unit 258 can each detect the number of residual persons. Each of these detection results may be stored in the residual database 243 in association with the building block, or the detection results may be compared and the residuals having the same position in each section are regarded as the same person. The number of survivors may be estimated and the result may be stored in the survivor database 243.

Then, the residual person information presentation unit 259 refers to the residual person database 243 and the map information database 241 to display the position (section) where the residual person exists on the display unit 22 on a map. In this map information, in addition to the plan map information of the building, at least the presence or absence of residuals is displayed for each section represented on the plan map. In addition, the number of survivors and the evacuation rate may be displayed. Here, the number of survivors is the number of survivors in each section stored in the survivor database 243, and the evacuation rate is obtained by subtracting the number of survivors from the number of residents in the section in normal times. It is calculated by dividing the number of people by the number of people in the same area in normal times. Then, based on the residual information displayed on the display unit 22, the operator selects the speaker with a microphone 6 to talk to the detected residual, or selects the IP camera 7 to observe the situation. Can be done. As a result, the operator can give an appropriate evacuation order to the remaining person. In addition, the operator will rescue the self-defense fire brigade and the public fire brigade dispatched based on the fire report for the remaining people (rescuers who need rescue) who are difficult to evacuate due to injury or disability. You can request it.

Further, the information transmission unit 433 reads the terminal position information stored in the terminal position database 423 based on the request for the terminal position information from the general operation panel 2 received by the information reception unit 431, and the general operation panel. Send to 2. Further, when the information transmission unit 433 receives information on the relative positional relationship (urgency) with the fire floor for each terminal 5 from the general operation panel 2, the information transmission unit 433 refers to the message database 422 and acquires the corresponding fire warning message. , Send to terminal 5.

1-3. Operation of the disaster prevention system 100 Next, an example of the operation of the disaster prevention system 100 will be described with reference to FIGS. 7 to 14. Specifically, the operation at the time of fire broadcasting, the operation at the time of detecting the residual person, the operation at the time of displaying the residual information, the operation at the time of the fire alarm using e-mail, and the operation at the time of closing the fire prevention shutter S'are explained. do.

1-3-1. Operation during fire broadcasting First, an example of the operation of the disaster prevention system 100 during fire broadcasting will be described with reference to FIG. 7.

When a fire breaks out, if the fire receiver 1 determines a fire based on the fire detection signal from the fire detector D (Sa1), the fire receiver 1 transmits fire information to the general operation panel and receives information from the general operation panel 2. Unit 251 receives fire information from the fire receiver 1 (Sa2). The display control unit 252 of the general operation panel 2 displays a map image showing the fire position on the display unit 22 based on the fire information (Sa3). Further, the fire alarm unit 253 of the general operation panel 2 refers to the equipment database 242 based on the information, and fires for each speaker 6 with a microphone (in the figure, "speaker 6 with a microphone" is referred to as "speaker"). The relative positional relationship with the floor is specified, and control information is generated in which the relative positional relationship with the specified fire floor is associated with the address of the speaker 6 with a microphone (Sa4). Even if the fire alarm unit 253 of the general operation panel 2 stores information indicating the degree of urgency based on the relative positional relationship with the specified fire floor in the equipment database 242 in association with the address of the speaker 6 with a microphone. good. Then, the information transmission unit 255 of the general operation panel 2 transmits this control information to the emergency broadcasting equipment 3 (Sa5). When information indicating the degree of urgency based on the relative positional relationship with the specified fire floor is stored in the equipment database 242 in association with the address of the speaker 6 with a microphone, the information transmission unit 255 is based on this information. You may do it.

When the information receiving unit 351 of the emergency broadcasting equipment 3 receives the control information (Sa6), the broadcasting control unit 352 of the emergency broadcasting equipment 3 refers to the message database 342 and acquires the corresponding fire warning message. (Sa7). Then, the information transmission unit 353 of the emergency broadcasting equipment 3 transmits a fire alarm message to be output for each of the speakers with microphones 6 toward each of the speakers with microphones 6 (Sa8).

Each speaker 6 with a microphone that has received the fire alarm message outputs the received message by voice (Sa9). At that time, the speaker 6 with a microphone arranged on the fire floor outputs a voice message "A fire broke out on this floor.", And the speaker 6 with a microphone arranged on the floor directly above "below this." A fire broke out on the floor of the building. " Further, the speaker 6 with a microphone arranged on the floor directly below may output the message "A fire broke out on the floor above this" by voice. That is, each speaker 6 with a microphone arranged on a floor with high urgency outputs a fire alarm message expressing the fire floor in a relative positional relationship with the floor on which the speaker is arranged. The resident who hears this message can easily grasp the situation (for example, the urgency of evacuation) in which he / she is located, even if he / she cannot recognize the floor on which he / she is located. Here, since the fire warning message is output by voice, it is particularly effective for the visually impaired. The speaker 6 with a microphone, which is arranged on a floor other than the floor with high urgency, outputs a message "A fire broke out in this building" by voice.

1-3-2. Operation at the time of residual residue detection Next, an example of the operation of detecting the residual residue will be described. In this embodiment, three detection methods are used: residual detection using a speaker 6 with a microphone, residual detection using an IP camera 7, and residual detection using a terminal 5. An example of the operation of the disaster prevention system 100 according to the detection method will be described with reference to FIGS. 8 to 10. In the present embodiment, the operation of detecting the residual person is performed when a fire occurs, but the operation of detecting the residual person is performed after the evacuation guidance is completed, and the evacuation completion is confirmed when the residual person is not detected by any of the detection methods. You can also do it.

When the information transmission unit 255 of the general operation panel 2 detects the operation of the operation unit 23 for searching for the residual person by the operator after starting the fire broadcasting, the disaster prevention system 100 starts the operation of detecting the residual person. Further, regardless of the above operation by such an operator, after the emergency broadcasting equipment 3 starts the fire broadcasting and a predetermined time elapses based on the fire information received by the information receiving unit 251 of the general operation panel 2. The operation of residual residue detection may be started.

1-3-2-1. Operation at the time of residual residue detection using the microphone-equipped speaker 6 First, an example of the operation at the time of residual residue detection using the microphone-equipped speaker will be described with reference to FIG. As described above, when the operation of residual agent detection is started, the disaster prevention system 100 starts the operation of residual agent detection using the speaker 6 with a microphone (Sb1). In this operation, a call message is output by voice from speakers 6 with microphones arranged on each floor of the building, and the presence of the call message is determined based on the sound information of the residual person reacting to the call message. ..

The voice output of the call message from the speaker 6 with a microphone is sequentially performed in order of increasing urgency. This calling order is determined in descending order of urgency based on the relative positional relationship of each speaker with a microphone 6 with the fire floor specified in step Sa3 (Sb2). When the fire alarm unit 253 of the general operation panel 2 stores information indicating the degree of urgency based on the relative positional relationship with the specified fire floor in the equipment database 242 in association with the address of the speaker 6 with a microphone. May determine the calling order based on the stored urgency information. Here, the floor with high urgency is a floor relatively close to the fire floor, and is determined by the relative positional relationship with the fire floor (more specifically, the vertical positional relationship). Specifically, the order may be the fire floor, the floor directly above, the floor directly below, and the other floors. For example, if a fire breaks out on the 3rd floor of a 5-story building, the order of calling is "3rd floor (fire floor) → 4th floor (directly above) → 2nd floor (directly below) → other floors". can do.

When the calling order is determined, the information transmission unit 255 of the general operation panel 2 provides a very large amount of control information for sequentially outputting the calling message by voice from the speakers with microphones 6 arranged on each floor according to the determined calling order. It is transmitted to the broadcasting equipment 3 (Sb3). The emergency broadcasting equipment 3 receives this control information at the information receiving unit 351 (Sb4). Then, the broadcast control unit 352 of the emergency broadcasting equipment 3 refers to the message database 342 based on the control information and acquires the corresponding message (Sb5). Then, as information related to the acquired message with the address included in the control information, the control information is transmitted from the information transmission unit 353 in order to output the acquired message to the speaker 6 with a microphone specified by the address (the information transmission unit 353). Sb6), the general operation panel 2 is notified that this has been executed (Sb7).

Each speaker 6 with a microphone that has received the call message outputs the received message by voice (Sb8). After outputting the message by voice, the speaker with microphone 6 (in the figure, the "speaker with microphone 6" that collects sound is referred to as "microphone") picks up the surrounding sound for a predetermined time and picks up the picked up sound. The audio information including the indicated audio signal and its own address is transmitted to the general operation panel 2 via the emergency broadcasting equipment 3 (Sb9). For example, the broadcast control unit 352 of the emergency broadcasting equipment 3 notifies the general operation panel 2 that the control information for outputting a message to the speaker 6 with a microphone has been transmitted via the communication unit 31 (Sb7), and further. , The information receiving unit 351 receives the voice information from the speaker 6 with a microphone, and the communication unit 31 transmits the received voice information to the general operation panel 2 (Sb9). Then, the information reception unit 251 of the general operation panel 2 receives the voice information from the microphone-equipped speaker 6 that outputs the call message from the emergency broadcasting equipment 3 via the communication unit 21 (Sb10).

When the first residual determination unit 256 of the general operation panel 2 receives the voice information, it refers to the equipment database 242 and identifies the section corresponding to the address included in the information (Sb11). When the section is specified, the first residual determination unit 256 determines at least the presence or absence of a residual person based on the voice signal included in the received voice information (Sb12). At this time, if a residual person is detected (YES in Sb12), the residual person information presenting unit 259 reads out the map information of the area (for example, the floor) to which the section belongs from the map information database 241 and obtains the map information. Residual information (presence or absence of residuals, number of residuals) is superimposed on the section position and projected onto the display unit 22 on the display control unit 252 (Sb13). If no residue is detected (NO in Sb12), the process proceeds to the next step Sb14. At this time, with respect to the section in which the residual residue is detected, the intensity difference or position is obtained by detecting a different sound pattern from the voice information or by comparing with the voice information from another speaker with a microphone 6 installed in the section. The number of residuals may be detected by detecting the number of different vocalization positions based on the phase difference or the like. Other well-known or known techniques may be used to detect the number of residuals. Then, the presence / absence or the number of detected residuals is stored in the residuals database 243 as residuals information in association with the section specified in step Sb11 (Sb14).

In this way, it is determined whether or not the residual information is stored for all the speakers 6 with microphones (Sb15), and if there is a speaker 6 with microphones for which the residual information is not yet stored (NO of Sb15). ), Returning to step Sb3, the call message is output by voice from the next speaker 6 with a microphone according to the call order, and the voice information is received. On the other hand, when the residual information is stored for all the speakers with microphones 6 (YES in Sb15), the residual determination process is terminated.

The output of the fire alarm message from the speaker 6 with a microphone during the above-mentioned call and sound collection is temporarily stopped, and the output of the fire alarm message is restarted when the call and sound collection are completed. To control. As a result, the fire warning message does not interfere with the operation of residual detection. Further, after the process of determining the residual residue is completed (when YES in Sb15), the operation of detecting the residual residue may be executed again, or may be repeatedly executed at a predetermined cycle. Further, in the above-described embodiment, the call from the speaker with microphone 6 is performed in the order of urgency to detect the residual person, but the present invention is not limited to this, and all the speakers with microphone 6 call at the same time. , And the residual residue may be detected in order based on the audio signal picked up from the speaker 6 with a microphone in the order of urgency.
The above is a description of the operation at the time of detecting a residual person using the speaker 6 with a microphone.

According to the operation at the time of detecting the residual person, the presence or absence of the residual person or the number of people can be automatically specified. In addition, by calling in order from the floor with the highest urgency, it is possible to preferentially identify the presence or absence or the number of survivors on the floor with the highest urgency.

1-3-2-2. Operation at the time of residual residue detection using the IP camera 7 Next, an example of the operation at the time of residual residue detection using the IP camera 7 will be described with reference to FIG. Similar to the operation of the residual person detection by the speaker 6 with a microphone described above, when the operation of the residual person detection is started, the disaster prevention system 100 is based on the image information from the IP cameras 7 arranged on each floor of the building. The operation of determining the presence of a residual person is started (Sc1).

When the operation of detecting the residual residue using the IP camera 7 is started, the information transmission unit 255 of the general operation panel 2 determines the camera image acquisition order, which is the order in which the camera images are acquired in descending order of urgency (Sc2). ). As described above, the camera image acquisition order, which is the order in which the IP camera 7 is requested to take an image, is the equipment in which the fire alarm unit 253 of the general operation panel 2 associates the urgency information specified at the time of a fire with the address of the IP camera 7. If it is stored in the database 242, it can be determined based on the stored urgency information. The determination of the camera image acquisition order is not limited to the above, and may be determined based on the urgency derived based on the relative positional relationship from the position where the fire occurred. When a fire breaks out on the 3rd floor of a 5-story building, the order of camera image acquisition is, for example, "3rd floor (fire floor) → 4th floor (directly above) → 2nd floor (directly below) → 5th floor (5th floor). (Upper floors of other floors) → 1st floor (lower floors of other floors) ". If there are multiple IP cameras 7 with the same urgency, for example, if multiple IP cameras 7 are arranged on the same floor and the relative positional relationship with the fire floor is the same, priority is given to places where evacuation is difficult. The order of imaging may be determined in a predetermined order, such as imaging and detecting the residuals at an early stage, or the section in which the residuals are detected by another residual detection method is preferentially imaged and detected. You may want to confirm the information of the survivors who have been evacuated at an early stage. The information transmission unit 255 transmits an image pickup request to the IP camera 7 via the communication unit 21 in the determined camera image acquisition order (Sc3).

Upon receiving the imaging request, the IP camera 7 starts imaging the surroundings, and obtains an image signal indicating the captured image (still image or moving image) and the address of the IP camera 7 (that is, an address that is self-identification information). The included image information is transmitted to the general operation panel 2 (Sc4).

The image information from the IP camera 7 is received by the information reception unit 251 of the general operation panel 2 via the communication unit 21 (Sc5). Then, the second residual determination unit 257 refers to the equipment database 242 based on the image information received by the information reception unit 251 to identify the section corresponding to the address included in the information (Sc6), and is accepted. Based on the image signal included in the image information, it is determined whether or not there is a residue (Sc7). At this time, the second residual determination unit 257 may determine at least the presence or absence of residuals by using an image analysis technique, and further determine the number of residuals.

When a residual person is detected in step Sc7 (with Sc7), the residual person information presenting unit 259 reads out the map information of the area (for example, floor) to which the section belongs from the map information database 241 and this map. Residual information (presence or absence of residuals, number of residuals) is superimposed on the relevant section position of the information, and the display control unit 252 displays the information on the display unit 22 (Sc8), and the process proceeds to the next step Sc9. If no residue is detected in step Sc7 (no Sc7), the process proceeds to step Sc9. Then, the presence / absence or the number of detected residuals is stored in the residuals database 243 in association with the section specified in step Sc6 (Sc9).

Then, for all the IP cameras 7, it is determined whether or not the residual information is stored or whether the imaging request is transmitted (Sc10), and the residual information is not yet stored or the imaging request is not yet stored. If there is an IP camera 7 that has not been transmitted (NO in Sc10), the process returns to step Sc3, and an imaging request is made to the next IP camera 7 according to the camera image acquisition order determined in Sc2. On the other hand, when the residual information is stored for all the IP cameras 7 (YES in Sc10), the residual determination process is terminated.

The fire warning message was temporarily stopped when the residual person was detected using the speaker 6 with a microphone, but it is not necessary to stop the fire warning message when the residual person is detected using the IP camera 7. Further, after the process of determining the residual residue is completed (when YES of Sc10), the operation of detecting the residual residue may be executed again, or may be repeatedly executed at a predetermined cycle.
The above is the description of the operation at the time of residual residue detection using the IP camera 7.

1-3-2-3. Operation at the time of residual residue detection using the terminal 5 Next, an example of the operation at the time of residual residue detection using the terminal 5 will be described with reference to FIG. Similar to the operation of detecting the residual person by the speaker 6 with a microphone described above, when the operation of detecting the residual person is started, the disaster prevention system 100 determines the residual person based on the position information of the terminal 5 carried by the resident. The operation of determining the existence is started (Sd1).

When the operation of detecting the residual person using the terminal 5 is started, the information transmission unit 255 of the general operation panel 2 transmits the terminal position information as control information for determining the presence or absence of the residual person remaining in the building. The request is transmitted to the support server 4 via the communication unit 21 (Sd2). The information receiving unit 431 of the support server 4 receives this transmission request via the communication unit 41 (Sd3).

When the support server 4 receives the terminal position information transmission request, the information transmission unit 433 makes a position information transmission request to the terminal 5 via the communication unit 41 (Sd4). The support server 4 does not wait for the terminal position information transmission request from the general operation panel 2, but periodically makes a position information transmission request to the terminal 5 to acquire the terminal position information from the terminal 5. May be good.

When the information receiving unit 562 of the terminal 5 receives this transmission request via the communication unit 51, the information transmitting unit 561 transmits its own position information based on the positioning unit 54 to the support server 4 via the communication unit 51. (Sd5).

When the information receiving unit 431 receives the terminal position information from the terminal 5 via the communication unit 41, the support server 4 stores the received terminal position information in the terminal position database 423 in association with the terminal ID. If the terminal position information is already stored in association with the terminal ID, the information is updated with the newly received terminal position information (Sd6). Then, the information transmission unit 433 of the support server 4 refers to the terminal position database 423 to acquire the terminal position information for each terminal ID, and the terminal position information for each terminal ID acquired via the communication unit 41 is used as the comprehensive operation panel. It is transmitted to 2 (Sd7).

In the general operation panel 2, the information receiving unit 251 receives the terminal position information from the support server 4 via the communication unit 21 (Sd8). The third residual determination unit 258 of the general operation panel 2 refers to the map information database 241 based on the terminal position information received by the information reception unit 251 to specify the division located for each terminal 5, and the terminal for each division. The presence or absence of, that is, the presence or absence of a residue is determined (Sd9). Then, the presence or absence of the detected residuals or the number of residuals is stored in the residuals database 243 as the residuals information in association with the specified section, and the residuals information presenting unit 259 remains in descending order of urgency from the residuals database 243. In addition to reading out the person information, the map information of the area (for example, the floor) to which the section where the residual person exists is read out from the map information database 241 and the residual person information read out from the residual person database 243 at the relevant section position of this map information (for example, the residual person information ( The presence / absence of residuals and the number of residuals) are superimposed and projected onto the display unit 22 as a map display on the display control unit 252 (Sd10).
The above is the description of the operation at the time of residual residue detection using the terminal 5.

1-3-3. Operation at the time of displaying the residual person information Next, an example of the operation of the general operation panel 2 at the time of displaying the residual person information will be described.

As described above, the comprehensive operation panel 2 has, in order of increasing urgency, in each of the residual detection using the speaker 6 with a microphone, the residual detection using the IP camera 7, and the residual detection using the terminal 5. The residual person information is displayed on the display unit 22 as a map, but the present invention is not limited to this. For example, the residual person information stored in the residual person database 243 may be read out in descending order of urgency, and the section in which the residual person exists may be displayed on the display unit 22 as a map as described above.

As a result of the above-mentioned operation of the residual person detection, the information on the presence or absence of the residual person or the number of people in each section is recorded in the residual person database 243 of the comprehensive operation panel 2. Then, the residual information presenting unit 259 of the comprehensive operation panel 2 sequentially acquires the residual information from the residual database 243 in descending order of urgency, and causes the display control unit 252 to display the residual information on the display unit 22. .. At this time, the display control unit 252 reads the map information of the area (for example, the floor) to which the section belongs from the map information database 241 and stores the residual information (presence or absence of residuals, residuals) at the section position of the map information. The number of people) is overlapped and displayed on the display unit 22. The map information at this time may be map information of all floors of the building or map information of a specific floor.

In this way, by displaying the residual person information in order of increasing urgency, based on the display of the display unit 22, the operator of the disaster prevention center or the like can refer to the residual person existing on the floor with high urgency. , Can respond quickly. Finally, the residual information is displayed for all floors and parcels.

The residual information includes the residual information based on the call using the speaker 6 with a microphone, the residual information based on the image information captured by the IP camera 7, and the residual information based on the position information of the terminal 5. When determining only the presence or absence of residuals for each section, the logical sum of these residuals information is obtained so that it indicates that the residuals have been detected by one of the detection methods, and the residuals are detected by the detection method. Leakage may be reduced. In the present embodiment, the operation of detecting the residual residue is performed when a fire breaks out, but when the operation of detecting the residual residue is performed after the evacuation guidance is completed and no residual substance is detected by any of the detection methods, the section is divided. You can confirm the completion of evacuation.

Further, when determining the number of residuals for each section, the number of residuals detected for each of the above-mentioned residual residual detection methods may be represented, or the position coordinates of the residuals detected by different detection methods may be used. If there is a clear match, it may be determined that they are the same person, duplication may be excluded, and the number of survivors may be represented as a determination result by a plurality of detection methods.

Further, based on the image information captured by the IP camera 7, the position information of the terminal 5, or both, the number of people in the museum is detected in normal times in the same manner as the operation at the time of detecting the residual person described above. It may be stored in the residual person database 243 as the information on the resident in normal times. It should be noted that the normal resident information is periodically detected and updated until a fire breaks out, and the latest normal resident information is stored in the residual person database 243. Then, in the event of a fire, it is possible to derive an evacuation rate indicating the evacuation status for each section based on the number of survivors in each section and the number of residents in the same section in normal times. Then, this evacuation rate may be superimposed on the relevant section position of the map information together with the residual person information and displayed on the display unit 22. By doing so, the operator of the disaster prevention center or the like can grasp the evacuation situation of each section based on the display of the display unit 22 and can respond promptly.

Here, an example of a map screen in which the number of remaining persons and the evacuation rate are displayed on the display unit 22 will be described with reference to FIG.

On the map screen illustrated in the figure, as map information of the building, a plan map display M of a specific floor having a plurality of sections and symbols C1 to C4 indicating the installation position of the IP camera 7 arranged on the floor are displayed. , The symbols S1 to S7 indicating the installation position of the speaker 6 with a microphone arranged on the floor, and the residual information displays R1 to R4 for each section are shown. The symbols C1 to C4 and S1 to S7 are camera buttons C1 to C4 (particularly need to be distinguished) for selecting and operating the IP camera 7 on the operation unit 23 which is a touch panel provided on the display unit 22. If not, it is referred to as "camera button Cm") and speaker buttons S1 to S7 for selecting and operating the speaker 6 with a microphone (referred to as "speaker button Sn" when it is not necessary to distinguish them). There is.

Here, for convenience, the description of the small compartments in which the speakers S5 to 7 with microphones are arranged will be omitted, and the first to fourth compartments will be described. Residual information displays R1 to R4 indicate the number of remaining persons and the evacuation rate in each section. The residual information displays R1 to 4 are displayed for each detection method, or are displayed in association with each of the camera button C indicating the IP camera 7 and the speaker button Sn indicating the speaker with a microphone 6, which are the respective detection means. May be good. In FIG. 11, as a result of integrating the determinations by the plurality of detection methods, the number of survivors and the evacuation rate for each section are shown. This evacuation rate is the number of people who evacuated from the area, that is, the number of people who evacuated from the area, which is the number of people who were in the same area in normal times. Calculated by dividing by. Here, it is assumed that the number of normal residents in each section is 10, and the number of detected residuals and the evacuation rate calculated based on the number are shown. That is, the evacuation rate R1 of the first section is (10-5 people) / 10 people = 50%, and the evacuation rate R2 of the second section is (10-3 people) / 10 people = 70%, the third. The evacuation rate R3 of the plot is (10 people-1 person) / 10 people = 90%, and the evacuation rate R4 of the fourth division is (10 people-4 people) / 10 people = 60%. Instead of this evacuation rate, the number of remaining persons in the section may be expressed by the residual rate divided by the number of people present in the section in normal times.

In FIG. 11, the broken line indicating the boundary between the second section and the third section is not divided by a fire wall, but is partitioned by a partition, a board wall, or the like that does not have fire resistance, or any partition. Indicates a virtual boundary that indicates the detection limit without it. Such a space is originally one section as a fireproof section. However, if there is some kind of partition, the speaker 6 with a microphone cannot emit sound at a sufficient volume and cannot collect sound satisfactorily to the resident or the remaining person on the opposite side, and the IP camera 7 has a field of view. I can't catch it. Further, even if there is no partition at this boundary, the same applies to the case where the space has a wide area beyond the detection range of the speaker 6 with a microphone and the IP camera 7. In such a case, in order to detect the resident or the residual person in each area divided by the boundary, a plurality of speakers 6 with a microphone and an IP camera 7 as the residual person detecting means are used and arranged in each area. , Treat these as separate compartments. In this respect, the fire detecting means is also similar in that the fire is arranged at a position where the fire can be detected.

The symbols of the speaker button Sn and the camera button Cm shown may be displayed in different modes depending on the respective situations. For example, when the residue detection is being executed, the display may be blinked or the display color may be changed (for example, orange). Further, for example, when a residual residue is detected, the blinking display may be performed at an earlier cycle, or the display color may be changed to a different display color (for example, a warning color such as red). Further, for example, when the residual residue is not detected, the display may be lit or changed to a different display color (for example, green, white, black). Further, for example, when a resident is present in normal times, the display color may be different from that when the resident is not present (for example, blue).

In addition, a pictogram imitating the shape of a person as shown in the figure may be displayed in the section where the residual person exists so that the existence of the person can be intuitively grasped. In addition, the pictogram display mode may be changed according to the number of survivors. For example, the number of pictograms may be changed or the size of pictograms may be changed according to the number of people so that the number of survivors can be intuitively grasped.

According to the operation at the time of displaying the residual information, the operator who operates the general operation panel 2 can list the residual status of a plurality of sections in the building. In addition, the operator can easily visually understand the positional relationship of the remaining persons. In addition, when the self-defense fire brigade takes over the activities to the public fire brigade that arrived by the report, it becomes easy to convey information on the residual situation.

1-3-4. Manual operation by the operator on the residual information display screen On the map screen illustrated in FIG. 11, the operator selects an arbitrary IP camera 7 by a manual operation using the operation unit 23, and displays a camera image from the selected IP camera 7. It is possible to select and project the image, or to select an arbitrary speaker 6 with a microphone and use the selected speaker 6 with a microphone to make a call or make a call. This manual operation will be described with reference to FIG. 12 in an example in which the IP camera 7 is selected, the situation is grasped by the camera image, and then the speaker 6 with a microphone is selected to establish a telephone line.

As described above, when a fire breaks out, the fire receiver 1 receives the fire information transmitted by determining the fire based on the fire detection signal from the fire detector D, and the general operation panel 2 receives the fire position based on the fire information. Is displayed on the display unit 22 (see Sa1 to Sa3 in FIG. 7). Further, the map image of the selected floor is displayed on the display unit 22 by the manual operation of the operation unit 23 by the operator who selects the floor to be displayed (Se1 in FIG. 12).

On this map screen, when the operator selects an arbitrary camera button Cm using the operation unit 23 (Se2), the information transmission unit 255 makes an imaging request including the address of the IP camera 7 corresponding to the selected camera button Cm. , The IP camera 7 is transmitted via the communication unit 21 (Se3).

The IP camera 7 that has received the imaging request starts imaging the surroundings (Se4), and integrates the image information including the image signal indicating the captured image (still image or moving image) and the address that is its own identification information. It is transmitted to the operation panel 2 (Se5).

When the transmitted image information is received by the information receiving unit 251 via the communication unit 21 of the general operation panel 2, the display control unit 252 displays the display unit 22 based on the image signal included in the received image information. Is displayed with a camera image (not shown) (Se6). The camera image is displayed superimposed on the map screen, for example.

On the other hand, when the operator selects an arbitrary speaker button Sn using the operation unit 23 on the map screen (Se7), the information transmission unit 255 makes a call including the address of the speaker 6 with a microphone corresponding to the selected speaker button Sn. The request is transmitted to the emergency broadcasting equipment 3 via the communication unit 21 (Se8).

When the transmitted call request is received by the information receiving unit 351 via the communication unit 31 of the emergency broadcasting equipment 3, the information transmitting unit 353 is identified by the address included in the received request. (Se9), and a telephone line is established between the speaker 6 with a microphone and the general operation panel 2 according to a predetermined communication protocol (Se10). As a result, it is possible to make a call between the operator who operates the general operation panel 2 and the remaining person who exists in the vicinity of the speaker 6 with a microphone. The established communication line is disconnected in response to the disconnection request transmitted from the general operation panel 2.
The above is the description of the operation of the manual operation by the operator on the residual information display screen.

According to the residual information display screen, the operator can visually confirm the current status of the desired section by a simple operation of selecting the camera button Cm on the map screen. In addition, the operator can talk to the remaining person existing in the desired section by a simple operation of selecting the speaker button Sn on the map screen.

1-3-5. Operation at the time of fire alarm using e-mail Next, an example of the operation of the disaster prevention system 100 at the time of fire alarm using e-mail will be described with reference to FIG.

When a fire occurs, when the fire receiver 1 determines a fire based on the fire detection signal from the fire detector D (Sf1), the fire receiver 1 transmits fire information to the general operation panel 2 and the information of the general operation panel 2 The reception unit 251 receives fire information from the fire receiver 1 (Sf2). The display control unit 252 of the general operation panel 2 displays a map image showing the fire position on the display unit 22 based on the fire information (Sf3). Up to this point, the operation is the same as during fire broadcasting (see Sa1 to 3 in FIG. 7).

When the fire alarm unit 253 of the general operation panel 2 receives the fire information, the fire alarm unit 253 transmits the terminal position information to the support server 4 via the information transmission unit 255 and the communication unit 21 in order to acquire the position information of each terminal 5. Send the request (Sf4). When the information receiving unit 431 of the support server 4 receives the terminal position information transmission request via the communication unit 41 (Sf5), the information receiving unit 431 transmits the position information transmission request to each terminal 5 via the communication unit 41 (Sf6). ..

When the information receiving unit 562 of the terminal 5 receives the position information transmission request from the support server 4 via the communication unit 51 (Sf7), the address included in the beacon signal acquired by the positioning unit 54 and the terminal ID of the own terminal The terminal position information including the above is transmitted to the support server 4 via the communication unit 51 (Sf8).

When the information receiving unit 431 of the support server 4 receives the terminal position information via the communication unit 41, the terminal position specifying unit 432 associates the terminal position information with the terminal ID included in the terminal position information and converts the terminal position information into the terminal position database 423. Store in. At this time, if the terminal position information is already stored in association with the terminal ID, the information is updated with the newly received terminal position information (Sf9). Then, the information transmission unit 433 of the support server 4 reads the terminal position information stored in the terminal position database 423 and transmits the read terminal position information to the general operation panel 2 via the communication unit 41 (Sf10). ..

The information reception unit 251 of the general operation panel 2 receives the terminal position information transmitted from the support server 4 via the communication unit 21. The fire alarm unit 253 of the general operation panel 2 refers to the map information database 241 based on the terminal position information received by the information reception unit 251 to identify the floor located for each terminal 5, and further refers to the fire floor. The relative positional relationship is specified (Sf11). Then, the information on the relative positional relationship with the specified fire floor is associated with the terminal ID of the terminal 5 and transmitted to the support server 4 via the information transmission unit 255 and the communication unit 21 (Sf12).

When the information reception unit 431 of the support server 4 receives the information on the relative positional relationship of each terminal 5 with the fire floor transmitted from the general operation panel 2 via the communication unit 41, a message is sent based on the received information. Refer to database 422 to get the corresponding fire alert message. Further, the information transmission unit 433 refers to the terminal information database 421 to acquire the e-mail address of the corresponding terminal 5, and generates an e-mail containing the acquired fire warning message with the acquired e-mail address as the destination (Sf13). .. Then, the information transmission unit 433 transmits the e-mail generated via the communication unit 41 to the terminal 5 (Sf14).

This e-mail is received by the destination terminal 5 (Sf15). When the e-mail is opened, a fire warning message indicating the relative positional relationship of the terminal 5 with the fire floor is displayed.

For example, the fire warning message of the e-mail sent to the terminal 5 on the fire floor is "A fire broke out on this floor.", And the fire of the e-mail sent to the terminal 5 on the immediate upper floor The warning message is "A fire broke out on the floor below this", and the fire warning message in the e-mail sent to the terminal 5 on the floor directly below is "A fire broke out on the floor above this." . ". That is, the terminal 5 existing on the floor with high urgency displays a fire warning message expressed by the relative positional relationship between the floor on which the terminal 5 exists and the fire floor. The resident who sees this message can easily grasp the situation (for example, the urgency of evacuation) in which he / she is located even if he / she cannot recognize the floor on which he / she is located. Here, since the fire warning message is output as visual information, it is particularly effective for the hearing impaired. The fire warning message of the e-mail sent to the terminal 5 existing on the floor other than the floor with high urgency is, for example, "A fire broke out in this building."
The above is the description of the operation at the time of fire alarm using e-mail.

1-3-6. Operation when the fire protection shutter S'is closed Next, an example of the operation of the disaster prevention system 100 when the fire protection shutter S'is closed will be described with reference to FIG. In this operation, when the fire protection shutter S'is closed, a warning message notifying that the fire protection shutter S'is in the closing operation is output by voice from the speaker 6 with a microphone in the vicinity thereof. As a result, the fire protection shutter S'is clearly notified to the surrounding people that the closing operation is in progress, and the person is prevented from being pinched. In the past, the buzzer provided near the fire shutter S'was sounded, but even if it can be recognized as some kind of warning, it does not explicitly notify that the fire shutter S'is in the closing operation. There wasn't.

When the fire / smoke prevention / exhaust device S is activated (Sg1), the fire receiver 1 comprehensively operates the terminal device operation information including the address of the activated fire / smoke / smoke prevention / exhaust device S via the second communication unit 12. It is transmitted to the board 2 (Sg2). Here, it is assumed that the fire protection shutter S'is activated as the fire protection / smoke prevention device S. The terminal device operation information corresponding to the fire protection shutter S'is an example of the automatic closing device operation information. At this time, the type of the device may be specified based on the activated fire prevention / smoke prevention device S and the equipment database 151, and the terminal device operation information including the address and the specified type may be transmitted.

In the general operation panel 2, when the information reception unit 251 receives the terminal device operation information from the fire receiver 1 via the communication unit 21, the fire alarm unit 253 fire prevention and smoke prevention device included in the received terminal device operation information. Based on the address of S, the equipment database 242 is referred to, and it is determined whether or not the type of the device is the fire prevention shutter S'(Sg3). At this time, if the terminal device operation information includes the type of device indicating the fire protection shutter S', the determination in step Sg3 may be performed accordingly.

When the "device type" of the activated fire prevention / smoke prevention device S is the fire prevention shutter S', the fire alarm unit 253 is arranged in the vicinity of the fire prevention shutter S'with reference to the equipment database 242. Select the address of the speaker 6 with a microphone (Sg4). As the speaker 6 with a microphone selected at this time, the speaker 6 closest to the fire protection shutter S'may be selected. In addition to the speaker 6 with a microphone installed as an emergency broadcasting facility, a speaker may be additionally installed in the vicinity of the fire shutter S'for each fire shutter S', and this may be selected.

When the speaker 6 with a microphone is specified, the fire alarm unit 253 determines whether the specified speaker 6 with a microphone is the output target of the fire alarm message (Sg5). Then, if it is not the output target of the fire alarm message, the process proceeds to step Sg6 in order to output a warning message notifying that the fire prevention shutter S'is in the closing operation from the speaker 6 with a microphone. On the other hand, when the specified speaker 6 with a microphone is the output target of the fire warning message, the output of the fire warning message is temporarily stopped until the output of the warning message is stopped. Specifically, the control information for causing the speaker 6 with a microphone to output an alarm message is not transmitted to the emergency broadcasting equipment 3. Further, when the control information for outputting the alarm message to the speaker with the microphone 6 is output, the control information for stopping the output of the alarm message from the speaker with the microphone 6 is transmitted to the emergency broadcasting equipment 3. Then, the process proceeds to step Sg6.

In step Sg6, the control information for causing the specified speaker 6 with a microphone to output a warning message notifying that the fire protection shutter S'is in the closing operation by voice is associated with the address, and the information is transmitted via the communication unit 21. The transmission unit 255 transmits this control information to the emergency broadcasting equipment 3 (Sg6).

In the emergency broadcasting equipment 3, when the information receiving unit 351 receives the control information for outputting this warning message by voice via the communication unit 31, the broadcasting control unit 352 refers to the message database 342 based on the control information. To get the corresponding message. Then, control information is generated (Sg7) to output the acquired message to the speaker 6 with a microphone specified by the address as information associated with the address included in the control information, and the generated control is generated. Information is transmitted from the information transmission unit 353 via the communication unit 31 (Sg8). Upon receiving this control information, the speaker with a microphone outputs a warning message informing that the fire protection shutter S'is in the closing operation (Sg9).

Next, when the activated fire protection shutter S'completes the closing operation (Sg10), the information reception unit 251 of the general operation panel 2 receives the terminal device operation confirmation information regarding the fire protection shutter S'from the fire receiver 1 (Sg11). .. At this time, the warning message of the speaker 6 with a microphone, which was correspondingly outputting the warning message, is stopped. Specifically, control information for stopping the output of the warning message to the speaker 6 with a microphone is transmitted to the emergency broadcasting equipment 3 (Sg12). When the information receiving unit 351 of the emergency broadcasting equipment 3 receives this control information via the communication unit 31, the information transmitting unit 353 directs the control information for stopping the warning message to the speaker 6 with a microphone at the address. Is transmitted via the communication unit 31 (Sg13). When the speaker 6 with a microphone receives this control information, it stops outputting a warning message notifying that the fire protection shutter S'is in the closing operation (Sg14).

When the speaker 6 with a microphone at the address is targeted to output a fire alarm message, the suspended fire alarm message is output. At this time, the information transmission unit 255 of the general operation panel 2 transmits the control information for outputting the fire alarm message to the emergency broadcasting equipment 3. When the information receiving unit 351 of the emergency broadcasting equipment 3 receives this control information via the communication unit 31, the information transmitting unit 353 directs the control information for outputting an alarm message to the speaker 6 with a microphone at the address. Is transmitted via the communication unit 31. When the speaker 6 with a microphone receives this control information, it outputs a fire alarm message by voice.

The warning message output by the speaker 6 with a microphone is, for example, a message such as "The fire shutter is closed", and the sound is repeatedly output until the closing is completed. The resident who hears this message can recognize that the nearby fire protection shutter S'is in the closing operation, and can avoid being pinched by the fire protection shutter S'. Here, since the fact that the fire protection shutter S'is in the closing operation is notified by a voice message, the resident can easily understand the fact as compared with the conventional warning sound. It is also particularly effective for the visually impaired. When the operation of the fire prevention shutter S'is completed, the warning message is stopped, and when it should be output, the fire warning message is output by voice. The output of the warning message may time out based on the scheduled closing time of the fire protection shutter S'. As a result, it is possible to prevent a state in which a warning message is output more than necessary at the time of incomplete operation.
The above is the description of the operation when the fire protection shutter S'is closed.

2. Modification Example The above embodiment may be modified as follows. Further, the following modified examples may be combined with one or more other modified examples.

2-1. Modification 1
In the above-mentioned operation during fire broadcasting, the fire floor may be expressed by the relative positional relationship with the floor even in the fire warning message broadcast on a floor other than the floor with high urgency. For example, when the fire floor is the 3rd floor and the floor on which the fire warning message is broadcast is the 5th floor, the message "A fire broke out on the second floor downstairs" may be broadcast. When this variant is adopted, the message database 342 of the emergency broadcasting equipment 3 broadcasts to each floor other than the highly urgent floor (for example, the floor above the fire floor or the floor two floors below the fire floor). The fire warning message for this purpose is associated with the degree of urgency, and the fire warning message expressing the fire floor in the relative positional relationship with the floor is stored and held. Then, when the broadcast control unit 352 specifies a fire warning message to be broadcast on a floor other than the floor with high urgency, the broadcast control unit 352 refers to the message database 342 and specifies the message corresponding to the floor. By doing so, it is possible to inform all the people in the building of the relative positional relationship between the position where they are and the fire floor and prompt them to make an accurate evacuation decision.

2-2. Modification 2
The beacon signal transmitting unit included in the fire detector D may be separated from the fire detector D and arranged in various places in the building as a beacon transmitter. In that case, the beacon transmitter periodically transmits a beacon signal on which an address, which is its own identification information, is superimposed. The terminal 5 that has received the beacon signal transmits the terminal position information including the address included in the received beacon signal and the terminal ID of the own terminal to the support server 4. The equipment database 242 of the general operation panel 2 that receives the terminal position information via the support server 4 holds in advance the address of the beacon transmitter and the installation location in association with each other. Then, when the fire alarm unit 253 or the third residual determination unit 258 of the general operation panel 2 receives the terminal position information, the fire alarm unit 253 or the third residual determination unit 258 refers to the equipment database 242 for the section and floor corresponding to the address included in the information. To identify.

Alternatively, the beacon signal transmitting unit included in the fire detector D may be integrated with or provided with the speaker 6 with a microphone or the IP camera 7. In that case, the beacon signal transmitting unit may periodically transmit a beacon signal on which the addresses of the integrated or annexed devices are superimposed.

2-3. Modification 3
The microphone portion included in the speaker with a microphone 6 may be separated from the speaker portion and arranged in the building. In that case, the microphone portion is arranged in the same section as the separated speaker portion, and is associated with the speaker portion in the equipment database 242 of the general operation panel 2.

2-4. Modification 4
In the operation at the time of detecting the residual person using the speaker with a microphone 6 described above, the residual person is called in order from the floor with the highest urgency, and each time the voice information is received from the speaker 6 with a microphone, the residual person is sequentially retained. Although the presence or absence of a person is determined, the remaining persons may be called all at once, and the presence or absence of a residual person may be determined in order from the floor with the highest urgency. When this modification is adopted, the information transmission unit 255 of the general operation panel 2 simultaneously voices a call message calling to the remaining persons remaining in the building from the speakers 6 with microphones arranged on each of the plurality of floors. Control information is transmitted to the emergency broadcasting equipment 3 so that it can be output. Therefore, the information transmission unit 255 identifies the speakers with microphones 6 arranged on each floor with reference to the equipment database 242, and for all the identified speakers 6 with microphones, the message database 342 of the emergency broadcasting equipment 3 Send the call message stored in. On the other hand, the first residual determination unit 256 of the general operation panel 2 determines the presence or absence of residuals based on the sound picked up by the microphone arranged in the vicinity of the speaker from which the call message is output as voice. , The presence or absence of residuals is determined in order from the floor with the highest urgency among multiple floors. Here, the microphone arranged in the vicinity of the speaker is a microphone arranged on the same floor as the speaker and associated with the speaker. For example, the microphone closest to the speaker. In this modification, the microphone included in the speaker 6 with a microphone corresponds to the microphone. Hereinafter, a detailed operation example of the disaster prevention system 100 will be described with reference to FIG.

Similar to the above-described embodiment (Sb1), when the operation of detecting the residual residue is started (Sh1), the information transmission unit 255 of the general operation panel 2 sends a call message to all the speakers 6 with microphones. The control information to be output as audio is transmitted to the emergency broadcasting equipment 3 (Sh2). The first residual determination unit 256 is based on the voice information transmitted from each speaker with a microphone 6 when, for example, the information reception unit 251 receives a notification from the emergency broadcasting equipment 3 that the call message has been transmitted. The voice information processing order, which is the order in which the process of detecting the residual material is executed, is determined (Sh3). Here, the voice information processing order is determined in descending order of urgency based on the fire information from the fire receiver 1. After that, the information receiving unit 251 sequentially receives voice information from each speaker with a microphone 6 (Sh4) according to the voice information processing order determined in step Sh3, refers to the equipment database 242, and sets the address included in the information. Identify the corresponding compartment (Sh5). When the section is specified for the voice information, the first residual determination unit 256 determines the presence or absence of a residual person based on the voice signal included in the voice information to be processed (Sh6). At this time, the number of survivors may be determined in the same manner as in the above-described embodiment. Then, the detected information on the presence or absence of the residual person and the number of people is associated with the section specified based on the voice information to be processed in step Sh5, and stored in the residual person database 243 as the residual person information (Sh7). When the residual person information is stored, the first residual determination unit 256 determines whether or not all the voice information has been processed (Sh8), and if not processed (NO of Sh8), returns to step Sh4. When the processing is performed (YES of Sh8), the processing is terminated.
The above is a description of the operation at the time of detecting a residual person using the speaker 6 with a microphone according to this modification.

The presence or absence of residuals and the number of residuals can be automatically specified by the operation at the time of detecting the residuals. In addition, by processing the voice information in order from the floor with the highest urgency, it is possible to preferentially identify the presence / absence and the number of survivors on the floor with the highest urgency.

2-5. Modification 5
In the operation at the time of fire alarm using the above mail, even in the fire alarm message transmitted to the terminal 5 existing on the floor other than the floor with high urgency, the fire floor is in the relative positional relationship with the floor. It may be expressed by. For example, as described above, when the fire floor is the 3rd floor and the floor where the terminal 5 is located is the 5th floor, the message "A fire broke out on the second floor below" may be output. .. When this modification is adopted, the message database 422 of the support server 4 is output to each floor other than the highly urgent floor (for example, the floor two floors above the fire floor or the floor two floors below the fire floor). The fire warning message of is associated with the degree of urgency, and the fire warning message expressing the fire floor in the relative positional relationship with the floor is stored and held. Then, when the information transmission unit 433 of the support server 4 specifies a fire warning message to be transmitted to the terminal 5 existing on a floor other than the floor with high urgency, the information transmission unit 433 refers to this message database 422. Identify the message that corresponds to that floor. By doing so, the person who owns the terminal 5 can know his / her position by the relative positional relationship with the fire floor from anywhere in the building, so that an accurate evacuation judgment can be made.

2-6. Modification 6
The terminal 5 transmits the address of the fire detector D superimposed on the beacon signal to the support server 4 as the position information of the own terminal, but receives the beacon signal transmitted from the access point of the wireless LAN. Then, the positioning of the own terminal may be performed based on the radio wave strength. At that time, the terminal 5 may be used in combination with PDR (pedestrian dead reckoning). Alternatively, the current position of the terminal 5 can be determined by equipping the terminal 5 with a beacon transmitter, installing beacon receivers in various places in the building, and determining the beacon receiver that has received the beacon signal transmitted from the terminal 5. It may be specified. In that case, when the beacon receivers installed in various parts of the building receive the beacon signal transmitted from the terminal 5, the terminal ID included in the signal and the address of the own unit are transmitted to the comprehensive operation panel via the support server 4. The current position of the terminal 5 may be specified by making a call to 2 and specifying the position or section corresponding to the received address on the side of the general operation panel 2. Alternatively, the terminal 5 may adopt another positioning method to acquire the position information of the own terminal. For example, as positioning systems using artificial satellites, GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo, IRNSS (Indian Regional Navigational Satellite System), quasi-zenith satellite system QZSS (Quasi-Zenish Satellite System), etc. May be adopted. In addition, as indoor positioning systems that cannot use satellite radio waves of positioning systems using these artificial satellites, pseudo-satellite GPS (sudolight), GPS repeater, IMES (Indoor Messaging System), wireless LAN positioning system, iBeacon (registered trademark), etc. A beacon transmitting means such as Eddystone using Bluetooth Low Energy (BLE), a positioning system based on an electronic sign such as a QR code (registered trademark) or an electronic tag, a positioning method using a sound wave signal, or the like may be adopted. When the terminal position information acquired in this way is given as the position coordinates, the fire alarm unit 253 or the third residual determination unit of the general operation panel 2 that has received this as the position coordinates is the map information database 241. By comparing with the map information, the section or floor where the terminal 5 is located may be specified.

2-7. Modification 7
The above support server 4 receives the address of the fire detector D superimposed on the beacon signal as position information from the terminal 5, but if the building is equipped with an entry / exit management system, entry / exit management The location information of the terminal 5 may be managed based on the entry / exit information acquired from the system.

Alternatively, the location information of the terminal 5 is not acquired via the support server 4, but the location information fixedly set for each resident is associated with the terminal ID of the resident terminal 5 to be associated with the terminal position database 423. It may be stored in. Here, the position information fixedly set for each resident is, for example, information indicating the position of the section where the resident is staying on a daily basis. When the location information of the resident is fixedly set, the terminal to which the fire warning message is sent does not necessarily have to be portable. That is, the terminal according to the present invention may be a stationary computer device that is used daily by the resident.

2-8. Modification 8
The number of people in the museum in normal times is detected by either the detection result of the second residual determination unit 257 based on the image information of the IP camera 7 or the detection result of the third residual determination unit 258 based on the position information of the terminal 5. The detection result of is used, or both detection results may be used.

Further, the detection of the residual person includes the detection result of the first residual determination unit 256 based on the call from the speaker 6 with a microphone, the detection result of the second residual determination unit 257 based on the image information of the IP camera 7, and the position of the terminal 5. Of the detection results of the third residual determination unit 258 based on the information, at least one or more detection results may be used. When one of the detection results is used, the evacuation completion of the section can be confirmed when the residual person detection operation is performed after the evacuation guidance is completed and the residual person is not detected.

2-9. Modification 9
The operation at the time of displaying the residual person information may be executed by using the terminal 5 instead of the general operation panel 2. At that time, the residual person information presentation unit 259 of the general operation panel 2 refers to the residual person information stored in the residual person database 243 and superimposes it on the map screen acquired from the map information database 241 to superimpose the residual person in each section. Image information indicating the information may be generated, the generated image information may be transmitted to the terminal 5 via the support server 4, and the display unit 52 of the terminal 5 may display the residual information on the map.

2-10. Modification 10
The plane map displayed on the above map screen (see FIG. 11) is an example of map information. The map information displayed on the map screen may be a three-dimensional map or a vertical cross-section map. In that case, the map information stored in the map information database 241 may be image data representing a three-dimensional map or a vertical cross-sectional map according to the displayed map. Further, the type of the map displayed on the map screen may be arbitrarily switched.

2-11. Modification 11
In the above-mentioned operation when the fire prevention shutter S'is closed, the fire alarm unit 253 of the general operation panel 2 refers to the installation location (section, etc.) stored in the equipment database 242 in the vicinity of the fire prevention shutter S'. Alternatively, although the speaker 6 with a microphone closest to the fire shutter S'is specified, the speaker 6 with a microphone associated with the fire shutter S'in advance may be specified in the database.

2-12. Modification 12
The type of the fire alarm message to be output from the microphone-equipped speaker 6 was determined by the general operation panel 2, but the emergency broadcasting equipment was based on the fire information from the fire receiver 1 or the general operation panel 2. 3 may be determined. Therefore, the emergency broadcasting equipment 3 further has an area of the equipment database 341 for storing the address of the speaker 6 with a microphone and the installation location specified by the section and the floor in the storage unit 34 (see FIG. 4). ). When the information reception unit 351 of the emergency broadcasting equipment 3 receives the fire information that identifies the fire floor, the broadcasting control unit 352 refers to the equipment database 341 and determines the relative positional relationship with the fire floor for each speaker 6 with a microphone. Identify. Then, the corresponding fire alarm message is read from the message database 342, and the information transmission unit 353 transmits the control information associated with the fire alarm message specified for each address of the speaker 6 with a microphone from the communication unit 31. Upon receiving this control information, the speaker 6 with a microphone outputs a fire warning message that expresses the fire floor in a relative positional relationship with the floor on which it is installed.

Further, the equipment database 341 also stores the fire protection shutter S'in association with the address and the installation location. The information receiving unit 351 of the emergency broadcasting equipment 3 receives the address of the activated fire prevention shutter S'from the fire receiver 1 or the general operation panel 2, so that the broadcasting control unit 352 is closest to the fire prevention shutter S'. Alternatively, the corresponding speaker 6 with a microphone can be specified, and the warning message read from the message database 342 can be output by voice.

The equipment database 341 may be mirrored by acquiring and storing the corresponding information from the equipment database 242 of the general operation panel 2 via the communication line L2.

2-13. Modification 13
The position information such as the floor or section where the terminal 5 exists is specified by referring to the equipment database 242 or the map information database 241 of the general operation panel 2 based on the terminal position information acquired by the positioning unit 54 of the terminal 5. However, the support server 4 may specify it. Therefore, the support server 4 is provided with an equipment database (not shown) that stores the address of the beacon and the installation location specified by the floor and the section in association with each other. The support server 4 can identify the floor and the section where the terminal 5 exists by referring to the above-mentioned equipment database provided by the support server 4 based on the terminal position information acquired from the terminal 5.

When the terminal position information is coordinate information based on various positioning systems, a map information database (not shown) that stores divisions and floors in a building as coordinate information is provided instead of the above equipment database. In this case, the support server 4 can compare the terminal position information acquired from the terminal 5 with the information in the map information database provided by the support server 4 to identify the floor and the section indicated by the coordinate information of the terminal 5. can.

2-14. Modification 14
The support server 4 may further include a residual person database (not shown) that stores residual person information for each section so that the residual person information can be viewed from the terminal 5. For example, the residual database may be mirrored by acquiring and storing the corresponding information from the residual database 243 of the general operation panel 2 via the communication line L2. Further, the support server 4 may function as a Web server that generates and distributes a Web page on which the residual information can be browsed by using the browser provided in the terminal 5.

Further, in addition to the above-mentioned residual information, the support server 4 stores the image information captured by the IP camera 7, the audio information picked up by the speaker 6 with a microphone, and the audio output information as a log in the storage unit 42. May be good. Further, similarly to the above-mentioned residual person information, the above-mentioned log may be accessed and confirmed from the terminal 5.

2-15. Modification 15
In the above-described embodiment, the floor with high urgency has been described as a floor relatively close to the fire floor, but the floor is not limited to this. It may be divided into an upper floor and a lower floor from the fire floor, and the floor closer to the fire floor on the upper floor side may be prioritized.

Further, for example, it can be appropriately determined for each building according to a fire fighting plan formulated according to the structure of the building. If a building is made up of multiple buildings, such as twin towers, which are connected by a corridor or the like and can be passed through for evacuation, the floor closer to the connecting floor than the fire floor, or the connecting floor away from the fire floor. The floor where the fire is located may be less urgent because it can be judged that the difficulty of evacuation is low. On the contrary, if there is a fire floor in the middle of the route to the connecting floor, which is the evacuation route, it is desirable to increase the urgency. In this way, the degree of urgency of each floor can be determined according to the relative positional relationship between the fire floor and the connecting floor that serves as an evacuation route.

2-16. Modification 16
In the above-described embodiment, the target for outputting a warning message from the nearby speaker 6 with a microphone during operation has been described as the fire protection shutter S'as an automatic closing device, but the present invention is not limited to this. If a device that operates automatically poses a danger to a person, the device is subject to output a warning message.
