The relative positional relationship with the fire floor is information indicating the level of urgency that should be taken, such as evacuation, for a fire. The highly urgent floor is a floor relatively close to the fire floor, specifically, at least the fire floor, and may include either the directly upper floor, the immediately lower floor, or both. The control information including the relative positional relationship with the fire floor is a simultaneous broadcast of the alarm message fire broadcast expressed by the relative position relationship (more specifically, the vertical positional relationship) from the speaker 6 with a microphone. It is used to make it output.

  In the fire broadcast at that time, in particular, the fire alarm message expressed by the relative positional relationship between the fire floor and the highly urgent floor is outputted from the microphone-equipped speaker 6 arranged on the urgent floor. . For example, from the speaker 6 with a microphone arranged on the fire floor, a message “A fire has occurred on this floor” is output as a voice. In addition, for example, from the speaker 6 with a microphone disposed immediately above the floor, a message “A fire has occurred on the floor below” is output as a voice, and the speaker 6 with a microphone disposed directly below the floor Causes the message “A fire has occurred on this floor” to be output. From the speakers 6 with microphones arranged on other floors, for example, a message excluding the relative positional relationship with the fire floor may be output, such as “A fire has occurred in this building.” "The fire has occurred on the upper (lower) floor." The relative positional relationship with the fire floor may be indicated more gently, and determined appropriately according to the fire fighting plan formulated for each building. It may be.

  The fire alarm unit 253 may store information indicating the level of urgency based on the relative positional relationship with the identified fire floor in the equipment database 242 in association with the address of the speaker 6 with a microphone. For example, “1” is attached to the speaker 6 with a microphone on the fire floor, “2” is attached to the speaker 6 with a microphone on the immediately upper floor, “3” is attached to the speaker 6 with a microphone on the immediately lower floor, and microphones on the other floors are attached. The speaker 6 stores “4” in the equipment database 242 in association with the address of the microphone-equipped speaker 6. The transmission of the control information to the information transmission unit 255 may be executed with reference to “information indicating the level of urgency (hereinafter referred to as urgency level)” stored in the equipment database 242. Information on the degree of urgency related to the microphone-equipped speaker 6 can also be used for residual detection in the first residual determination unit 256 described later.

  The fire alarm unit 253 may store the specified urgency level in the facility database 242 in association with the address of the IP camera 7. For example, “1” is assigned to the IP camera 7 on the fire floor, “2” is assigned to the IP camera 7 on the immediately upper floor, “3” is assigned to the IP camera 7 on the immediately lower floor, and “3” is assigned to the IP camera 7 on the other floors. “4” is stored in the facility database 242 in association with the address of the IP camera 7. Information on the degree of urgency related to the IP camera 7 can be used for residual detection in a second residual determination unit 257 described later.

  Further, the fire alarm unit 253 transmits a transmission request for terminal position information 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 location information transmitted from the support server 4 based on this transmission request is received by the information receiving 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 receiving unit 251, identifies the section and floor located for each terminal 5, and further relative to the fire floor Specify the positional relationship. And the information of the relative positional relationship with the identified fire floor is linked | related with terminal ID of the terminal 5, and it transmits to the support server 4 via the information transmission part 255 and the communication part 21. FIG. The relative positional relationship with the fire floor is information indicating the level of urgency that should be taken, such as evacuation, for a fire. The highly urgent floor is a floor relatively close to the fire floor, specifically, at least the fire floor, and may include either the directly upper floor, the immediately lower floor, or both. The information on the relative positional relationship with the fire floor is that 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). Used for

  At this time, the fire alarm unit 253 may store information indicating the level of urgency based on the relative positional relationship with the identified fire floor in the equipment database 242 in association with the terminal ID of the terminal 5. . For example, “1” is assigned to the terminal 5 on the fire floor, “2” is assigned to the terminal 5 on the immediately upper floor, “3” is assigned to the terminal 5 on the immediately lower floor, and “4” is assigned to the terminal 5 on the other floors. These are stored in the equipment database 242 in association with the terminal ID of the terminal 5, respectively. The transmission of the urgency level associated with the terminal ID to the support server 4 may be executed with reference to the urgency level stored in the equipment database 242.

  In addition, when the information reception unit 251 receives the terminal device operation information, the fire alarm unit 253 refers to the facility database 242 based on the address of the fire prevention and smoke control device S included in the terminal device operation information, and the type of the device Is a fire shutter S ′. When the type of the apparatus is the fire shutter S ′, the address of the microphone-equipped speaker 6 disposed in the vicinity of the fire shutter S ′ is specified. Then, control information for outputting a warning message for notifying that the fire shutter S ′ is in the closing operation from the speaker with microphone 6 at the specified address is output to the information transmission unit 255 in association with the address. Here, the microphone-equipped speaker 6 disposed in the vicinity of the fire shutter S ′ is the microphone-equipped speaker 6 disposed on the same floor as the fire shutter S ′ and associated therewith, for example, the fire shutter. This is the speaker 6 with a microphone closest to S ′. When the information receiving unit 251 receives the terminal device operation confirmation information related to the fire shutter S ′, it outputs control information for stopping the output of the warning message.

  When outputting the warning message, if the relative positional relationship with the fire floor is associated with the microphone-equipped speaker of the address, control to cause the microphone-equipped speaker 6 to perform the fire broadcast by temporarily canceling this Control information for stopping the information and outputting the warning message by voice is output. And if the information reception part 251 receives the terminal device operation confirmation information regarding the fire shutter S ′, the control information which associates the relative positional relationship with the fire floor after outputting the control information for stopping the output of the warning message. It is good to output fire broadcast from the said speaker with a microphone.

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

  The information transmission unit 255 transmits the control information from the fire alarm unit 253 to the emergency broadcast facility 3 via the communication unit 21. In addition, the information transmission unit 255 transmits the emergency level information for each terminal ID from the fire alarm unit 253 to the support server 4 via the communication unit 21.

  In addition, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual by the operator after starting the fire broadcast, the information transmission unit 255 sends an interrogation message to the remaining floor in the building to each floor of the building. Control information for sequentially outputting sound from the arranged speaker 6 with microphone is transmitted to the emergency broadcasting facility 3 via the communication unit 21. At that time, the call messages are sequentially output by voice in order from the most urgent floor among the plurality of floors of the building. Here, the urgent order is, in other words, the order close to the place where the fire occurred. On the floors that have the same vertical distance from the location of the fire, the upper floors are more urgent. For example, among fire floors, directly above floors and directly below floors, the fire floor is more urgent than the directly above floor, and the directly above floor is more urgent than the directly below floor. The information transmission unit 255 specifies the addresses of the microphone-equipped speakers 6 in descending order of urgency, and sequentially transmits control information for outputting a call message as a voice. The order of the urgent floors can be determined based on the relative positional relationship with the fire floor for each of the microphone-equipped speakers 6 already identified by the fire alarm unit 253. A first residual determination unit 256 described later determines the presence of a residual by the reaction of the residual to the challenge message. Note that the output of the interrogation message may be performed simultaneously from all the speakers 6 with microphones, and the first residual determination unit 256 may sequentially determine the presence of the remaining persons in order from the highest urgent floor. In addition, the information transmission unit 255 transmits the control information for residual detection after a predetermined time has elapsed since the start of the fire broadcast based on the fire information received by the information reception unit 251 regardless of the operation by the operator. You may transmit to the emergency broadcast equipment 3.

  In addition, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual by the operator after starting the fire broadcast, the information transmission unit 255 serves as control information for determining whether there is a residual in the building. An imaging request is transmitted to the IP camera 7 via the communication unit 21. At that time, as with the call message, the IP camera 7 is sequentially requested to perform imaging in order from the most urgent floor among the plurality of floors of the building. An 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 described later determines the presence of a residual person. Note that the imaging request may be made to all the IP cameras 7 all at once, and the second residue determination unit 257 may sequentially determine the presence of the remaining person in order from the highest urgent floor. In addition, the information transmission unit 255 transmits the control information for residual detection after a predetermined time has elapsed since the start of the fire broadcast based on the fire information received by the information reception unit 251 regardless of the operation by the operator. You may transmit to IP camera 7.

  Further, during a normal period when no fire has occurred, the information transmission unit 255 sends an imaging request as control information for determining the presence or absence of a person present in the building to the IP camera 7 via the communication unit 21. You may send it. An image (still image or moving image) captured by the IP camera 7 is received by the information receiving unit 251, and a second residual determination unit 257 described later determines the presence of a person in the building. 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 presence of the person in the building. You may transmit an imaging request sequentially. A second residual determination unit 257, which will be described later, determines whether or not there is a resident in each section. In that case, you may make it the 2nd residual determination part 257 determine the number of people in a building for every division. The information on the detected resident can be stored in the residual database 243 as normal resident information and used for checking the evacuation status in the event of a fire, especially when the number of people in the gallery is stored. It can be used for evacuation rate calculation.

  Moreover, the information transmission part 255 may transmit the transmission request | requirement of terminal position information to the assistance server 4 regularly via the information transmission part 255 and the communication part 21 at the normal time when the fire does not generate | occur | produce. The terminal location information transmitted from the support server 4 based on this transmission request is received by the information receiving 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 described later determines the presence or absence of a resident at least for 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 / absence of a terminal for each section, that is, the presence / absence of a person in the building, and further, for each section. It is also possible to determine the number of terminals, that is, the number of people in the building. The information on the detected resident can be stored in the residual database 243 as normal resident information and used for checking the evacuation status in the event of a fire, especially when the number of people in the gallery is stored. It can be used for evacuation rate calculation.

  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. In addition, when the information transmission unit 255 detects the operation of the operation unit 23 for detecting the residual by the operator after starting the fire broadcast, the information transmission unit 255 serves as control information for determining whether there is a residual in the building. The terminal location information transmission request 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 a third residual determination unit 258 described later determines the presence of a residual person. In addition, the information transmission part 255 starts the fire broadcast based on the fire information received by the information reception part 251 and starts the terminal position information for the residual detection after a predetermined time has elapsed, regardless of the above operation by the operator. The transmission request may be transmitted to the support server 4.

  In addition, since the information transmission unit 255 uses the predetermined speaker 6 with a microphone to make a call, when the operator detects the operation of the operation unit 23 that selects the speaker 6 with a microphone, the information transmission unit 255 makes a call with the selected speaker 6 with a microphone. A call request as control information for sending is transmitted to the emergency broadcast facility 3 via the communication unit 21. For example, when the operator selects a speaker button Sn (n = 1, 2, 3,...) To be described later on the map screen displayed on the display unit 22, the selected speaker button Sn is referenced with reference to the equipment database 242. The address of the microphone-equipped speaker 6 corresponding to is specified, and a call request including the specified address is transmitted. When a call line is established with the microphone-speaker 6 selected via the emergency broadcast facility 3 based on the call request, the audio output control unit 254 receives the microphone-speaker received by the information receiving unit 251. Based on the audio signal from 6, the audio is output from the speaker 26. The information transmission unit 255 transmits the operator's voice signal input to the microphone 27 to the speaker 6 with microphone, and outputs the voice. In this way, the operator can talk with the remaining person through the selected speaker 6 with microphone.

  In addition, when the information transmission unit 255 detects an operation of the operation unit 23 for selecting the IP camera 7 by the operator in order to display the camera image from the predetermined IP camera 7 on the display unit 22, the information transmission unit 255 moves to the selected IP camera 7. An imaging request as control information for requesting imaging is transmitted to the IP camera 7 via the communication unit 21. For example, when the operator selects a 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 the equipment database 242. The address of the IP camera 7 corresponding to is specified, and an imaging request including the specified address is transmitted. When the information reception unit 251 receives an image signal from the IP camera 7 based on the imaging request, the display control unit 252 displays a 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 state of fire, the presence or absence of residual persons, and the state thereof.

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

  The second residual determination unit 257 determines at least the presence or absence of a residual person based on an image (still image or moving image) captured by the IP camera 7 that has received the imaging request. At this time, the second residual determination unit 257 may determine at least the presence or absence of a residual person using a known or publicly known image analysis technique, and may further determine the number of persons (for example, JP 2012-113367 A). Issue 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 determines at least whether or not there is a terminal for each section, that is, the residual person's The presence / absence may be determined, and the number of terminals per section, that is, the number of remaining persons may be determined.

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

  The residual information stored in the residual database 243 by the residual information presentation unit 259 indicates at least the presence or absence of a residual for each section. The first to third residual information may be stored separately in the residual database 243, or may be residual information based on the calculation results of the first to third residual information. For example, a logical sum of the first to third residual information may be taken and stored as residual information indicating the presence or absence of residuals, and detection errors of residuals due to the respective residual detection principles may be reduced. . For example, if there is a residual person who cannot speak, even if the first residual determination unit 256 cannot detect it, the second residual determination unit 257 can detect it based on the IP camera 7 that can image the section of the residual person. In addition, if the remaining person falls to the back side of the fixture and is in the blind spot of the IP camera 7, even if the second remaining determination unit 257 cannot detect it, the remaining person is carrying the terminal 5. The third residual determination unit 258 can detect. As described above, based on the detection results of the residuals by a plurality of methods, it is possible to supplement the detection omission due to the detection principle of each method and improve the detection accuracy of the residuals.

  Further, the residual information stored in the residual database 243 by the residual information presentation unit 259 may be the number of residuals for each section. In addition, in the normal period before the occurrence of a fire, the presence / absence and number of persons present in each section may be further stored using the remaining person information determined for each section as the resident information. And the presence or absence of the residual person for every division can be used for evacuation status confirmation by comparing with the presence or absence of the resident who exists in the same division in normal times. In addition, by dividing the number of people who remain in the same area by the number of people who are present in the same area in normal times, the number of people who are present in the same area in normal times is divided by the number of people in the same area. It is possible to calculate an evacuation rate indicating the evacuation situation.

  In order to detect the number of remaining persons, the first remaining determination unit 256, for example, distinguishes the remaining persons who speak by detecting different voice prints from the voice information received by the information receiving unit 251 and detects the number of persons remaining. can do. Also, for example, by comparing the voice information from other microphone-equipped speakers 6 installed in the same section, distinguishing the position where the residual person speaks based on the intensity difference, phase difference, etc., and detecting the number The number of remaining persons may be detected. Further, for example, a message for asking the number of remaining persons is included in the calling message, and the remaining persons are requested to report the number of remaining persons in the section. And the feature-value is extracted from the audio | voice information of the residual who the information reception part 251 received. Here, the feature amount is a numerical value indicating a physical feature of specific audio information such as MFCC and LPC. A message from the remaining person is obtained by comparing the feature quantity of the unique keyword “people” or “name” as a unit indicating the number of people and the similarity exceeds a predetermined threshold. 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 techniques known or publicly known may be used for detecting the number of remaining persons. In addition, the second remaining determination unit 257 can detect the number of remaining persons by using a known or well-known image analysis technique for the camera image received by the information receiving unit 251 (for example, JP 2012-113367 A). Issue no.). In addition, the third residual determination unit 258 detects the number of terminals existing in each section, that is, the number of persons remaining in the section carrying the terminal 5 based on the terminal position information received by the information receiving unit 251. Can do.

  In this way, the first residue determination unit 256, the second residue determination unit 257, and the third residue determination unit 258 can each detect the number of remaining persons. These detection results may be stored in the remnant database 243 in association with the sections of the building, or these detection results may be compared and the remaining persons having the same position in each section may be regarded as the same person. The number of the remaining persons may be estimated and the result may be stored in the remaining person database 243.

  The residual information presentation unit 259 refers to the residual database 243 and the map information database 241 and causes the display unit 22 to display a map of positions (sections) where the residuals exist. In this map information, in addition to the planar map information of the building, at least presence / absence of a residual person is displayed for each section represented on the planar map. Further, the number of remaining persons and the evacuation rate may be displayed. Here, the number of remaining persons is the number of remaining persons for each section stored in the remaining person database 243, and the evacuation rate is obtained by subtracting the number of remaining persons from the number of people present in the section in normal times. It is calculated by dividing the number of people who are present by the number of people present in the same block at normal times. Based on the residual information displayed on the display unit 22, the operator selects the speaker 6 with a microphone and talks to the detected residual, or selects the IP camera 7 and observes the situation. Can be. As a result, the operator can give an appropriate evacuation instruction to the remaining persons. In addition, for those who are unable to evacuate due to injury or disability, etc. and need to be rescued (rescue personnel), the operator should rescue the self-defense fire brigade or the public fire brigade dispatched based on the fire report. Can be requested.

Further, when a fire occurs, when the information reception unit 431 receives information on the relative positional relationship with the fire floor for each terminal 5 from the general operation panel 2 via the communication unit 41, the information reception unit 431 further stores the information in association with each other. Hold.

  Further, the storage unit 42 has a storage area for the message database 422. The message database 422 stores and holds a fire alarm message (text message) for notifying the occurrence of fire in order to notify the terminal 5 in association with the relative positional relationship with the fire floor. Specifically, for example, a message “Fire has occurred on this floor” is held in correspondence with the fire floor, and a message “A fire has occurred on the floor below” is displayed on the upper floor. The message “A fire has occurred on the floor above” is stored in association with the floor immediately below, and the message “A fire has occurred in the building” is displayed on the other floors. Is stored in association with each other.

[Control unit]
The control unit 43 is a control unit that controls the operation of each unit of the support server 4 by executing a program stored in the storage unit 42. The control unit 43 includes an arithmetic processing unit such as a CPU, and includes an information receiving unit 431, a terminal position specifying unit 432, and an information transmitting unit 433 as functional configurations.

  The information receiving unit 431 receives a terminal location information transmission request from the general operation panel 2 via the communication unit 41. The information receiving unit 431 receives information on the relative positional relationship with the fire floor for each terminal 5 from the general operation panel 2 via the communication unit 41. Further, the information receiving unit 431 receives terminal position information transmitted from the terminal 5 via the communication unit 41.

  The terminal position specifying unit 432 specifies the position where the terminal 5 carried by the person in the building is present. Specifically, when the terminal position information is received by the information receiving unit 431, it is stored in the terminal position database 423 in association with the terminal ID included in the terminal position information. 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.

  The information transmission unit 433 transmits a position information transmission request to the terminal 5 based on the terminal position information transmission request received by the information reception unit 431. In addition, the information transmission unit 433 reads out 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 2 to send. When the information transmission unit 433 receives information on the relative positional relationship (emergency) 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 alarm message. To the terminal 5.

1-3. Operation of Disaster Prevention System 100 Next, an example of the operation of the disaster prevention system 100 will be described with reference to FIGS. Specifically, the operation at the time of fire broadcasting, the operation at the time of detection of residual persons, the operation at the time of displaying residual information, the operation at the time of fire alarm using mail, and the operation at the time of closing the fire shutter S ′ are described. To 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.

  When a fire occurs, if the fire receiver 1 makes a fire determination 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 The 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 indicating the fire position on the display unit 22 based on the fire information (Sa3). 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 microphone” is expressed as “speaker”). The relative positional relationship with the floor is specified, and control information in which the relative positional relationship with the specified fire floor is associated with the address of the speaker 6 with microphone is generated (Sa4). Even if the fire alarm unit 253 of the general operation panel 2 stores information indicating the level of urgency based on the relative positional relationship with the identified fire floor in the facility 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 broadcast facility 3 (Sa5). When information indicating the level of urgency based on the relative positional relationship with the identified 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 based on this information. May be executed.

  When the information reception unit 351 of the emergency broadcast facility 3 receives the control information (Sa6), the broadcast control unit 352 of the emergency broadcast facility 3 refers to the message database 342 and acquires the corresponding fire alarm message. (Sa7). And the information transmission part 353 of the emergency broadcasting equipment 3 transmits the fire alarm message output for every speaker 6 with a microphone toward each speaker 6 with a microphone (Sa8).

  Each microphone-equipped speaker 6 that has received the fire warning message outputs the received message as a voice (Sa9). At that time, the microphone-equipped speaker 6 disposed on the fire floor outputs a voice message “A fire has occurred on this floor”, and the microphone-equipped speaker 6 disposed immediately above the floor “ The message “Fire broke out on the floor” is output. Further, the microphone-equipped speaker 6 disposed immediately below the floor may output a voice message “A fire has occurred on this floor”. That is, each microphone-equipped speaker 6 disposed on a highly urgent floor outputs a sound of a fire alarm message expressing the fire floor in a relative positional relationship with the floor where the speaker is disposed. Even if the resident who hears this message cannot recognize the floor on which he / she is present, he / she can easily grasp the situation in which he / she is placed (for example, the urgency of evacuation). Here, since the fire alarm message is output by voice, it is particularly effective for the visually impaired. Note that the microphone-equipped speaker 6 disposed on a floor other than the highly urgent floor outputs a voice message “A fire has occurred in this building”.

1-3-2. Next, an example of an operation for detecting a residual person will be described. In the present embodiment, three detection methods are used: residual detection using the speaker 6 with a microphone, residual detection using the IP camera 7, and residual detection using the 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. In this embodiment, the residual detection operation is performed in the event of a fire. However, the residual detection operation is performed after completion of the evacuation guidance, and when no residual is detected by any detection method, the completion of the evacuation is confirmed. You can also

  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 by the operator after starting the fire broadcasting, the information transmission unit 255 causes the disaster prevention system 100 to start the operation of detecting the residual. In addition, based on the fire information received by the information receiving unit 251 of the general operation panel 2 regardless of the above operation by such an operator, after the emergency broadcasting equipment 3 starts fire broadcasting and a predetermined time has elapsed, The operation for detecting the residual person may be started.

1-3-2-1. Operation at the time of residual detection using the speaker with microphone 6 First, an example of an operation at the time of detection of residual using the speaker with microphone will be described with reference to FIG. As described above, when the residual detection operation is started, the disaster prevention system 100 starts the residual detection operation using the speaker 6 with a microphone (Sb1). In this operation, an interrogation message is output from the microphone-equipped speaker 6 disposed on each floor of the building, and its presence is determined based on information of a sound that the remaining person has reacted to the interrogation message. .

  The voice output of the calling message from the microphone-equipped speaker 6 is sequentially performed in the order of higher urgency. This calling order is determined in the order of increasing urgency based on the relative positional relationship with the fire floor for each speaker 6 with microphone specified in step Sa3 (Sb2). When the fire alarm unit 253 of the general operation panel 2 stores information indicating the level of urgency based on the relative positional relationship with the identified fire floor in the equipment database 242 in association with the address of the speaker 6 with a microphone. The call order may be determined based on the stored information indicating the urgency. Here, the highly urgent floor is a floor relatively close to the fire floor, and is determined by the relative positional relationship (more specifically, the positional relationship in the vertical direction) with the fire floor. Specifically, the fire floor, the directly above floor, the directly below floor, and other floors can be used in this order. For example, if a fire broke out on the 3rd floor of a five-story building, the calling order would be “3rd floor (fire floor) → 4th floor (directly upper floor) → 2nd floor (directly below) → other floors” can do.

  When the calling order is determined, the information transmitting unit 255 of the general operation panel 2 provides emergency control information for sequentially outputting the calling messages from the microphone-equipped speakers 6 arranged on each floor according to the determined calling order. Is transmitted to the commercial broadcasting facility 3 (Sb3). The emergency broadcast facility 3 receives this control information at the information receiving unit 351 (Sb4). Then, the broadcast control unit 352 of the emergency broadcast facility 3 acquires a corresponding message by referring to the message database 342 based on the control information (Sb5). Then, as information relating the acquired message to the address included in the control information, 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 ( Sb6), the fact that this is executed is notified to the general operation panel 2 (Sb7).

  Each microphone-equipped speaker 6 that has received the calling message outputs the received message as a voice (Sb8). After outputting the message as voice, the speaker 6 with microphone (in the figure, “speaker 6 with microphone” is referred to as “microphone”) picks up the surrounding sound for a predetermined time and collects the collected sound. The voice information including the voice signal to be shown 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 broadcast facility 3 notifies the general operation panel 2 via the communication unit 31 that control information for outputting a message to the speaker 6 with a microphone has been transmitted (Sb7). Then, audio information from the microphone-equipped speaker 6 is received by the information receiving unit 351, and the received audio information is transmitted from the communication unit 31 to the general operation panel 2 (Sb9). And the information reception part 251 of the general operation panel 2 receives the audio | voice information from the speaker 6 with a microphone which output the calling message from the emergency broadcasting equipment 3 via the communication part 21 (Sb10).

  When receiving the voice information, the first remaining determination unit 256 of the general operation panel 2 refers to the equipment database 242 and identifies a 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 audio signal included in the received audio information (Sb12). At this time, if a remaining person is detected (YES in Sb12), the remaining person information presenting unit 259 reads out map information of an area (for example, a floor) to which the section belongs from the map information database 241, and the map information Residual information (presence / absence of remaining persons, number of remaining persons) is superimposed on the section position, and is displayed on the display unit 22 by the display control unit 252 (Sb13). If no remaining person is detected (NO in Sb12), the process proceeds to the next step Sb14. At this time, with respect to the section in which the remaining person is detected, a difference in intensity or level is detected by detecting a different voice pattern from the voice information or by comparing with voice information from other microphone-equipped speakers 6 installed in the section. The number of remaining persons may be detected by detecting the number of different utterance positions based on the phase difference or the like. Other techniques known or publicly known may be used for detecting the number of remaining persons. Then, the detected presence / absence or the number of remaining persons is stored in the remaining person database 243 as the remaining person 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). If there is a speaker 6 with microphones in which the residual information is not yet stored (NO in Sb15). ), Returning to step Sb3, in accordance with the calling order, the next speaker 6 with a microphone outputs a voice message and accepts the voice information. On the other hand, if the residual information is stored for all the microphone-equipped speakers 6 (YES in Sb15), the residual determination process is terminated.

The output of the fire alarm message from the microphone-equipped speaker 6 that is executing the above-described calling and sound collection is temporarily stopped, and the output of the fire alarm message is resumed when the calling and sound collection are finished. To control. As a result, the residual detection operation is not hindered by the fire alarm message. In addition, after the process for determining the residual person is completed (in the case of YES in Sb15), the residual person detection operation may be executed again or repeatedly at a predetermined cycle. In the above-described embodiment, the remaining persons are detected by calling from the microphone-equipped speakers 6 in the order of urgency. However, the present invention is not limited to this. The remaining persons may be sequentially detected based on the audio signals collected from the microphone-equipped speaker 6 in order of urgency.
The above is the description of the operation at the time of residual detection using the microphone-equipped speaker 6.

  According to the operation at the time of detecting the remaining person, it is possible to automatically specify the presence or absence of the remaining person or the number of persons. Further, by calling in order from the floor with the highest urgency, it is possible to preferentially specify the presence or absence or the number of persons on the floor with the higher urgency.

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

  When the residual detection operation using the IP camera 7 is started, the information transmission unit 255 of the general operation panel 2 determines the camera image acquisition order that 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 of requesting imaging to the IP camera 7, is the facility in which the fire alarm unit 253 of the general operation panel 2 associates the information on the urgency level specified at the time of the 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 emergency information. The determination of the camera image acquisition order is not limited to the above, and it may be determined based on the degree of urgency derived based on the relative positional relationship from the fire occurrence position. The order of camera image acquisition when a fire occurs on the third floor of a five-story building is, for example, “3rd floor (fire floor) → 4th floor (directly upper floor) → 2nd floor (directly lower floor) → 5th floor ( The upper floor of the other floor → the first floor (the lower floor of the other floor) ”. In addition, when there are a plurality of IP cameras 7 having the same urgency level, for example, when a plurality of 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 a place where it is difficult to evacuate. The order of imaging may be determined in a predetermined order, for example, by detecting images and detecting residuals at an early stage, or by preferentially imaging and detecting the areas where residuals are detected by other residual detection methods. You may make it confirm the information of the residual who is being done at an early stage. The information transmission unit 255 transmits an imaging request to the IP camera 7 via the communication unit 21 in the determined camera image acquisition order (Sc3).

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

  Image information from the IP camera 7 is received by the information receiving unit 251 of the general operation panel 2 via the communication unit 21 (Sc5). Then, based on the image information received by the information receiving unit 251, the second residual determination unit 257 identifies a section corresponding to the address included in the information with reference to the equipment database 242 (Sc 6) and is received. Based on the image signal included in the image information, the presence / absence of a remaining person is determined (Sc7). At this time, the second residual determination unit 257 may determine at least the presence or absence of a residual person using an image analysis technique, and may further determine the number of persons.

  If a residual person is detected in step Sc7 (Sc7 is present), the residual person information presentation unit 259 reads out map information of an area (for example, a floor) to which the section belongs from the map information database 241, and this map Residual information (the presence / absence of residual persons, the number of residual persons) is superimposed on the section position of the information, and is displayed on the display unit 22 by the display control unit 252 (Sc8), and the process proceeds to the next step Sc9. In Step Sc7, when no remaining person is detected (No in Sc7), the process proceeds to Step Sc9. Then, the presence / absence or the number of remaining persons detected is stored in the remaining person database 243 in association with the section identified in Step Sc6 (Sc9).

  Then, for all the IP cameras 7, it is determined whether or not the residual information has been stored or the imaging request has been transmitted (Sc10). The residual information has not been stored yet or the imaging request has not been received. 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 in accordance with the camera image acquisition order determined in Sc2. On the other hand, when the residual information is stored for all IP cameras 7 (YES in Sc10), the residual determination process is terminated.

The fire alarm message is temporarily stopped when the remaining person is detected using the microphone-equipped speaker 6. However, when the remaining person is detected using the IP camera 7, it is not necessary to stop the fire alarm message. In addition, after the process for determining the residual person is completed (in the case of Sc10 YES), the residual person detection operation may be executed again or repeatedly at a predetermined cycle.
The above is the description of the operation when the remaining person is detected using the IP camera 7.

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

  When the operation of detecting the remaining person using the terminal 5 is started, the information transmitting unit 255 of the general operation panel 2 transmits the terminal position information as control information for determining the presence / absence of the remaining person in the building. The request is transmitted to the support server 4 via the communication unit 21 (Sd2). The information reception 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 location information transmission request, the information transmission unit 433 makes a location 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 and periodically sends the position information transmission request to the terminal 5 to acquire the terminal position information from the terminal 5. Also good.

  When the information reception unit 562 of the terminal 5 receives this transmission request via the communication unit 51, the information transmission 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 terminal location information from the terminal 5 via the communication unit 41, the support server 4 stores the received terminal location information in the terminal location database 423 in association with the terminal ID. When 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 location database 423 to obtain terminal location information for each terminal ID, and uses the terminal location information for each terminal ID obtained via the communication unit 41 as a comprehensive operation panel. 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). Based on the terminal position information received by the information receiving unit 251, the third residual determination unit 258 of the general operation panel 2 identifies a block located for each terminal 5 with reference to the map information database 241, and a terminal for each block. It is determined whether or not there is a remaining person (Sd9). Then, it is stored in the residual database 243 as residual information in association with the detected presence or absence or number of remaining persons, and the residual information presentation unit 259 maintains residual information in order of higher urgency than the residual 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 remaining person belongs belongs is read out from the map information database 241, and the remaining person information ( The presence / absence of remaining persons and the number of remaining persons) are superimposed and displayed on the display unit 22 as a map display on the display control unit 252 (Sd10).
The above is the description of the operation when the remaining person is detected using the terminal 5.

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

  As described above, the general operation panel 2 is configured so that the remaining person detection using the microphone-equipped speaker 6, the remaining person detection using the IP camera 7, and the remaining person detection using the terminal 5 are performed in descending order of urgency. Although the residual information is displayed as a map on the display unit 22, the present invention is not limited to this. For example, the residual information stored in the residual database 243 may be read in descending order of urgency, and the sections where the residuals exist may be displayed on the display unit 22 as described above.

  In the remaining person database 243 of the general operation panel 2, as a result of the above-described residual detection operation, information on the presence or absence of the number of persons or the number of persons for each section is recorded. Then, the residual information presentation unit 259 of the general 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 residual information (the presence / absence of residual persons, the The number of persons) is superimposed and displayed on the display unit 22. In addition, the map information at this time may be map information of all the floors of the building, or may be map information of a specific floor.

  In this way, by displaying the residual information sequentially in descending order of urgency, based on the display on the display unit 22, the operator of the disaster prevention center can respond to the residuals present on the highly urgent floor. Can respond quickly. Finally, residual information is displayed for all floors and sections.

  The residual information includes residual information based on calling using the speaker 6 with microphone, residual information based on image information captured by the IP camera 7, and residual information based on position information of the terminal 5. When determining only the presence or absence of a residual person for each section, calculate the logical sum of these residual information and indicate that a residual person has been detected by one of the detection methods. Leakage may be reduced. In this embodiment, the residual detection operation is performed in the event of a fire, but the residual detection operation is performed after the completion of the evacuation guidance. The completion of evacuation can be confirmed.

  Further, when determining the number of remaining persons for each section, the number of remaining persons detected for each of the above-described remaining person detection methods may be represented, or the position coordinates of the remaining persons detected by different detection methods may be represented. If they clearly match, it may be determined that they are the same person, the duplication is excluded, and the number of remaining persons may be expressed as a determination result by a plurality of detection methods.

  In addition, based on either or both of the image information captured by the IP camera 7 and the position information of the terminal 5, the number of people in the building is detected in a normal manner in the same manner as the above-described operation at the time of residual detection, The information may be stored in the residual database 243 as information on the person who is currently in the building. The normal resident information is periodically detected and updated until a fire occurs, and the latest normal resident information is stored in the residual database 243. When a fire occurs, an evacuation rate indicating the evacuation status for each section can be derived based on the number of people remaining in each section and the number of people present in the section in normal times. Then, the evacuation rate may be displayed on the display unit 22 so as to overlap with the remaining person information at the section position of the map information. By doing in this way, the operator of a disaster prevention center etc. can grasp | ascertain the evacuation situation of each division based on the display of the display part 22, and can respond quickly.

  Here, an example of the 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.

  In the map screen illustrated in the figure, as map information of the building, a planar map display M of a specific floor having a plurality of sections, and symbols C1 to C4 indicating the installation positions of the IP cameras 7 arranged on the floor. And symbols S1 to S7 indicating the installation positions of the microphone-equipped speakers 6 disposed on the floor, and residual information displays R1 to R4 for each section. The symbols C1 to C4 and S1 to S7 are camera buttons C1 to C4 for selecting and operating the IP camera 7 in the operation unit 23 which is a touch panel provided on the display unit 22 (need to be particularly distinguished). If not, it is referred to as “camera button Cm”) and speaker buttons S1 to S7 for selecting and operating the microphone-equipped speaker 6 (referred to as “speaker button Sn” if there is no need to distinguish between them). Yes.

  Here, for the sake of convenience, description of the small sections where the microphone-equipped speakers S5 to S7 are disposed will be omitted, and the first section to the fourth section will be described. Residual information displays R1 to R4 indicate the number of people remaining in each section and the evacuation rate. The residual information displays R1 to R4 are displayed for each detection method, or are displayed in association with each of the camera buttons C indicating the IP camera 7 and the speaker buttons Sn indicating the microphone-equipped speaker 6 as detection means. Also good. In FIG. 11, as a result of integrating the determinations by a plurality of detection methods, the number of remaining persons and the evacuation rate for each section are represented. This evacuation rate is the number of people who were present in the same area during normal times. It is calculated by dividing by. Here, it is assumed that the number of normal residents in each section is 10, and the detected number of remaining persons 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%, the evacuation rate R2 of the second section is (10-3 people) / 10 people = 70%, the third The evacuation rate R3 of the section is (10 persons-1 person) / 10 persons = 90%, and the evacuation ratio R4 of the fourth section is (10 persons-4 persons) / 10 persons = 60%. Instead of this evacuation rate, it may be expressed by a residual rate obtained by dividing the number of people remaining in a division by the number of people present in the division in normal times.

  In addition, in FIG. 11, the broken line which shows the boundary of the 2nd division and the 3rd division is not necessarily divided by a fire wall, but is divided by a non-fire-resistant material such as a partition or a plate wall, or something which is partitioned. Even if not, a virtual boundary indicating a detection limit is shown. Such a space is originally one compartment as a fire prevention compartment. However, if there is some partition, the speaker 6 with a microphone cannot emit sound at a sufficient volume and cannot collect sound satisfactorily for the residents or the remaining people on the opposite side. Can not be caught. The same applies to a space having a wide area exceeding the detection range of the speaker 6 with the microphone and the IP camera 7 even if the boundary is not partitioned. In such a case, in order to detect the residents or the remaining persons in each area divided by the boundary, a plurality of speakers 6 with microphones and IP cameras 7 as the remaining person detecting means are arranged in each area. , Treat these as separate compartments. In this respect, the fire detection means is the same in that it is disposed at a position where a fire can be detected.

  The symbols of the speaker button Sn and the camera button Cm shown in the figure may be displayed in different modes depending on the situation. For example, when performing the residual detection, the display may be blinked or the display color may be changed (for example, orange). Further, for example, when a remaining person is detected, it may be blinked at an earlier cycle or may be changed to a different display color (for example, a warning color such as red). Further, for example, when no remaining person is detected, the display may be lit or changed to a different display color (for example, green, white, black). Further, for example, when there is a resident in normal times, a different display color (for example, blue) may be used.

  In addition, a pictogram that imitates the shape of a person as shown in the figure may be displayed in a section where a person remains, so that the presence of a person can be intuitively grasped. Moreover, you may change the display mode of a pictogram according to the number of remaining persons. For example, according to the number of people, the number of pictograms may be changed or the size of the pictograms may be changed so that the number of remaining persons 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 states 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 of the public fire brigade that arrived by notification, it becomes easier to communicate information on the residual situation.

1-3-4. Manual Operation by Operator on Residual Information Display Screen In the map screen illustrated in FIG. 11, the operator selects an arbitrary IP camera 7 by manual operation using the operation unit 23, and displays a camera image from the selected IP camera 7. The selected speaker 6 with a microphone can be selected and displayed, and the selected speaker 6 with a microphone can be used for calling or talking. This manual operation will be described with reference to FIG. 12 as an example in which the IP camera 7 is selected and the situation is grasped by a camera image, and then the speaker with microphone 6 is selected to establish a telephone line.

  As described above, when a fire occurs, the fire receiver 1 accepts fire information transmitted 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). Moreover, the map image of the selected floor is displayed on the display part 22 by manual operation of the operation part 23 by the operator who selects the floor to display (Se1 of FIG. 12).

  When the operator selects an arbitrary camera button Cm using the operation unit 23 on this map screen (Se2), the information transmission unit 255 issues an imaging request including the address of the IP camera 7 corresponding to the selected camera button Cm. Then, it transmits to the IP camera 7 via the communication unit 21 (Se3).

  The IP camera 7 that has received the imaging request starts imaging of the surroundings (Se4), and comprehensively acquires image information including an image signal indicating the captured image (still image or moving image) and an address that is identification information of itself. It transmits 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. A camera image (not shown) is displayed on (Se6). For example, the camera image is displayed superimposed on the map screen.

  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 includes a call including the address of the speaker 6 with microphone corresponding to the selected speaker button Sn. The request is transmitted to the emergency broadcast facility 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 broadcast facility 3, the information transmitting unit 353 identifies the speaker 6 with microphone identified by the address included in the received request. (Se9), and a telephone line is established between the speaker 6 with microphone and the general operation panel 2 according to a predetermined communication protocol (Se10). As a result, a call between the operator who operates the general operation panel 2 and the remaining person in the vicinity of the microphone-equipped speaker 6 can be performed. The established telephone line is disconnected in response to a disconnection request transmitted from the general operation panel 2.
This completes the description of the manual operation performed by the operator on the residual information display screen.

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

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

  When a fire occurs, if the fire receiver 1 makes a fire determination 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 information on the general operation panel 2 The accepting unit 251 accepts fire information from the fire receiver 1 (Sf2). The display control unit 252 of the general operation panel 2 displays a map image indicating the fire position on the display unit 22 based on the fire information (Sf3). Up to this point, the operation is the same as that during fire broadcasting (see Sa1 to Sa3 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. A request is transmitted (Sf4). When the information reception unit 431 of the support server 4 receives a transmission request for terminal position information via the communication unit 41 (Sf5), the information reception unit 431 transmits a transmission request for position information to each terminal 5 via the communication unit 41 (Sf6). .

  When the information reception unit 562 of the terminal 5 receives a 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, the terminal ID of the terminal itself, 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 location information via the communication unit 41, the terminal location specifying unit 432 associates the terminal location information with the terminal ID included in the terminal location information and stores the terminal location information in the terminal location database 423. To store. 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 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 identifies the floor located for each terminal 5 with reference to the map information database 241 based on the terminal position information received by the information reception unit 251, and further The relative positional relationship is specified (Sf11). And the information of the relative positional relationship with the identified fire floor is linked | related with terminal ID of the terminal 5, and it transmits to the support server 4 via the information transmission part 255 and the communication part 21 (Sf12).

  When the information receiving unit 431 of the support server 4 receives the information on the relative positional relationship with the fire floor for each terminal 5 transmitted from the general operation panel 2 via the communication unit 41, the message is received based on the received information. The corresponding fire alarm message is acquired with reference to the database 422. Further, the information transmission unit 433 acquires the mail address of the corresponding terminal 5 with reference to the terminal information database 421, and generates an e-mail describing the acquired fire alarm message with the acquired mail address as a destination (Sf13). . Then, the information transmission unit 433 transmits the electronic 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 alarm message indicating the relative positional relationship of the terminal 5 with the fire floor is displayed.

For example, the e-mail fire warning message sent to the terminal 5 located on the fire floor is “A fire has occurred on this floor.” The e-mail fire sent to the terminal 5 located immediately above the floor. The alarm message is "A fire has occurred on the floor below." The fire alarm message in the email sent to the terminal 5 on the floor immediately below is "A fire has occurred on this floor." . " That is, the terminal 5 present on the highly urgent floor displays a fire alarm message expressed by the relative positional relationship between the floor where the terminal 5 is located and the fire floor. Even if the resident who sees this message cannot recognize the floor in which he / she is present, he / she can easily grasp the situation where he / she is placed (for example, the urgency of evacuation). Here, since the fire alarm message is output as visual information, it is particularly effective for the hearing impaired. In addition, the fire alarm message of the e-mail transmitted to the terminal 5 existing on a floor other than the highly urgent floor is, for example, “A fire has occurred in this building”.
This completes the description of the operation at the time of fire alarm using e-mail.

1-3-6. Operation when Fire Shutter S ′ is Closed Next, an example of the operation of the disaster prevention system 100 when the fire shutter S ′ is closed will be described with reference to FIG. In this operation, when the fire shutter S ′ is closed, a warning message notifying that the fire shutter S ′ is being closed is output from the speaker 6 with a microphone in the vicinity thereof. This clearly notifies the surrounding people that the fire shutter S ′ is in the closing operation, and prevents people from being caught. Conventionally, a buzzer provided in the vicinity of the fire shutter S ′ has been sounded. However, even if it can be recognized as a warning, it does not explicitly notify that the fire shutter S ′ is in the closing operation. There wasn't.

  The fire receiver 1 operates the terminal device operation information including the address of the activated fire prevention / smoke device S via the second communication unit 12 when the fire prevention / smoke device S is activated (Sg1). It transmits to the board 2 (Sg2). Here, it is assumed that the fire-proof shutter S ′ is activated as the fire-proof and smoke-proof device S. The terminal device operation information corresponding to the fire 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 and smoke control device S and the equipment database 151, and the terminal device operation information including the address and the specified type may be transmitted.

  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 includes the fire prevention and smoke prevention device included in the received terminal device operation information. Based on the address of S, it is determined whether or not the type of the device is the fire shutter S ′ by referring to the equipment database 242 (Sg3). At this time, if the device type indicating the fire shutter S ′ is included in the terminal device operation information, the determination in step Sg3 may be performed based on this.

  When the “type of device” of the fire prevention / smoke / exhaust device S activated is the fire shutter S ′, the fire alarm unit 253 is disposed in the vicinity of the fire shutter S ′ with reference to the equipment database 242. The address of the microphone-equipped speaker 6 is selected (Sg4). As the speaker 6 with microphone to be selected at this time, a speaker closest to the fire shutter S ′ may be selected. In addition to the microphone-equipped speaker 6 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 selected.

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

  In step Sg6, control information for outputting a warning message for notifying that the fire shutter S ′ is being closed from the identified speaker 6 with microphone is associated with the address and information is transmitted via the communication unit 21. The transmission unit 255 transmits this control information to the emergency broadcast facility 3 (Sg6).

  In the emergency broadcast facility 3, when the information receiving unit 351 receives control information for outputting the warning message by voice via the communication unit 31, the broadcast control unit 352 refers to the message database 342 based on the control information. To get the corresponding message. Then, control information is generated 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 (Sg7), and the generated control Information is transmitted from the information transmission unit 353 via the communication unit 31 (Sg8). When receiving the control information, the speaker with microphone outputs a warning message notifying that the fire shutter S 'is in the closing operation (Sg9).

  Next, when the activated fire shutter S ′ completes the closing operation (Sg10), the information receiving unit 251 of the general operation panel 2 receives the terminal device operation confirmation information related to the fire shutter S ′ from the fire receiver 1 (Sg11). . At this time, the warning message of the microphone-equipped speaker 6 that has output the warning message correspondingly is stopped. Specifically, control information for stopping the output of the warning message to the speaker 6 with microphone is transmitted to the emergency broadcasting facility 3 (Sg12). When the information reception unit 351 of the emergency broadcasting facility 3 receives this control information via the communication unit 31, the information transmission unit 353 directs the control information for stopping the warning message to the speaker 6 with the microphone of the address. Then, the data is transmitted via the communication unit 31 (Sg13). Upon receiving this control information, the microphone-equipped speaker 6 stops outputting a warning message notifying that the fire shutter S ′ is being closed (Sg14).

  When the speaker 6 with a microphone of the address is a target for outputting a fire alarm message, the fire alarm message that has been temporarily stopped is output. At this time, the information transmission unit 255 of the general operation panel 2 transmits control information for outputting a fire alarm message to the emergency broadcasting facility 3. When the information reception unit 351 of the emergency broadcast facility 3 receives this control information via the communication unit 31, the information transmission unit 353 directs the control information for outputting an alarm message to the speaker 6 with the microphone of the address. To transmit via the communication unit 31. When the microphone-equipped speaker 6 receives this control information, it outputs a fire alarm message as a voice.

The warning message output by the microphone-equipped speaker 6 is, for example, a message such as “The fire shutter is closed.” The voice is repeatedly output until the closing is completed. A person who has heard this message can recognize that the nearby fire shutter S ′ is being closed and can avoid being caught by the fire shutter S ′. Here, since the fact that the fire shutter S ′ is being closed is notified by a voice message, the person in the building can easily understand the fact as compared with a conventional warning sound. It is particularly effective for visually impaired people. When the operation of the fire shutter S ′ is completed, the warning message is stopped, and when it should be output, a fire warning message is output as a sound. The output of the warning message may time out based on the scheduled time for the closing operation of the fire shutter S ′. Thereby, it is possible to prevent a warning message from being output more than necessary during an incomplete operation.
This completes the description of the operation when the fire shutter S ′ is closed.

2. Modifications The above embodiment may be modified as follows. The following modifications may be combined with one or more other modifications.

2-1. Modification 1
In the fire broadcast operation described above, the fire floor may be expressed as a relative positional relationship with the floor even in a fire alarm message broadcast to a floor other than the floor with high urgency. For example, when the fire floor is the third floor and the floor where the fire alarm message is broadcast is the fifth floor, the message “A fire has occurred on the second lower floor” may be broadcast. When this modification is adopted, the message database 342 of the emergency broadcasting facility 3 broadcasts to each floor other than the floor with high urgency (for example, the floor two floors above the fire floor and the floors two floors below the fire floor). The fire alarm message for performing is associated with the urgency level, and the fire alarm message expressing the fire floor in a relative positional relationship with the floor is stored and held. Then, when specifying a fire alarm message to be broadcast on a floor other than a highly urgent floor, the broadcast control unit 352 refers to the message database 342 and specifies a message corresponding to the floor. By doing so, it is possible to inform all the people in the building of the relative position relationship with the fire floor of the position where the person is and to prompt accurate evacuation judgment.

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

  Or the beacon signal transmission part with which said fire detector D is provided may be integrated with the speaker 6 with a microphone, or the IP camera 7, or may be provided side by side. In this case, the beacon signal transmission unit may periodically transmit a beacon signal on which an address of an apparatus that is integrated or installed is superimposed.

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

2-4. Modification 4
In the operation for detecting the remaining person using the above-mentioned speaker 6 with a microphone, the remaining persons are called in order from the floor with the highest urgency, and each time voice information is received from the speaker 6 with a microphone, The presence / absence of a person is determined, but the remaining persons may be called all at once, and the determination of the presence / absence of a person may be performed in order from the urgent floor. When this modification is adopted, the information transmission unit 255 of the general operation panel 2 simultaneously transmits an interrogation message calling on the remaining persons remaining in the building from the speakers 6 with microphones arranged on each of the plurality of floors. The control information is transmitted to the emergency broadcast facility 3 so as to be output. For this purpose, the information transmission unit 255 refers to the equipment database 242 to identify the microphone-equipped speakers 6 arranged on each floor, and the message database 342 of the emergency broadcasting equipment 3 for all the identified loudspeakers with microphone 6. The interrogation message stored in is transmitted. On the other hand, the first residual determination unit 256 of the general operation panel 2 determines the presence or absence of a residual person based on the sound collected by the microphone disposed in the vicinity of the speaker from which the call message is output as voice. The presence / absence of a remaining person is determined in order from the most urgent floor among the plurality of floors. Here, the microphone disposed in the vicinity of the speaker is a microphone disposed 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 microphone-equipped speaker 6 corresponds to the microphone. Hereinafter, a detailed operation example of the disaster prevention system 100 will be described with reference to FIG.

As in the above-described embodiment (Sb1), when the residual detection operation is started (Sh1), the information transmission unit 255 of the general operation panel 2 sends an interrogation message to all the speakers 6 with microphones. Control information to be output as audio is transmitted to the emergency broadcast facility 3 (Sh2). For example, when the information reception unit 251 receives a notification that the call message has been transmitted from the emergency broadcast facility 3, the first residual determination unit 256 is based on the audio information transmitted from each speaker 6 with a microphone. Then, the voice information processing order, which is the order in which the process for detecting the remaining person is executed, is determined (Sh3). Here, the voice information processing order is determined based on the fire information from the fire receiver 1 in order of increasing urgency. Thereafter, the information reception unit 251 sequentially receives audio information from each microphone-equipped speaker 6 (Sh4) in accordance with the audio information processing order determined in step Sh3, and refers to the equipment database 242 to set the address included in the information. The corresponding section is specified (Sh5). When the section is specified for the sound information, the first remaining determination unit 256 determines the presence or absence of a remaining person based on the sound signal included in the sound information to be processed (Sh6). At this time, the number of remaining persons may be determined as in the above-described embodiment. The detected information on the presence / absence of the remaining persons and the number of persons is associated with the section specified based on the audio information to be processed in step Sh5 and stored in the remaining person database 243 as the remaining person information (Sh7). When the residual information is stored, the first residual determination unit 256 determines whether or not all audio information has been processed (Sh8), and if not processed (No in Sh8), the process returns to step Sh4, If it has been processed (YES in Sh8), the process is terminated.
The above is the description of the operation at the time of residual detection using the microphone-equipped speaker 6 according to the present modification.

  The presence / absence of the remaining persons and the number of persons can be automatically specified by the operation at the time of detecting the remaining persons. In addition, by processing the voice information in order from the urgent floor, it is possible to preferentially specify the presence and the number of remaining persons on the urgent floor.

2-5. Modification 5
In the operation at the time of fire alarm using the above-mentioned mail, even in the fire alarm message transmitted to the terminal 5 existing on the floor other than the highly urgent floor, the fire floor is relative to the floor. It may be expressed as For example, as described above, when the fire floor is the third floor and the floor where the terminal 5 is located is the fifth floor, the message “Fire has occurred on the second lower floor” 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 and the floors below the fire floor). The fire alarm message is associated with the degree of urgency, and the fire alarm message expressing the fire floor in a relative positional relationship with the floor is stored and held. And the information transmission part 433 of the support server 4 refers to this message database 422, when specifying the fire alarm message transmitted also with respect to the terminal 5 which exists in floors other than a highly urgent floor, The message corresponding to the floor is specified. By doing in this way, the person who possesses the terminal 5 can know his / her position from the relative position relationship with the fire floor wherever he / she is in the building, and thus can make an accurate evacuation judgment.

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 terminal, but receives the beacon signal transmitted from the wireless LAN access point. Then, positioning of the terminal itself may be performed based on the radio field intensity. In that case, the terminal 5 may use PDR (pedestrian dead reckoning) together. Alternatively, a beacon transmitter is provided on the terminal 5 side, beacon receivers are installed at various locations in the building, and the current position of the terminal 5 is determined by 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 at various locations in the building receive the beacon signal transmitted from the terminal 5, the terminal ID included in the signal and the address of the own device are received via the support server 4 via the integrated operation panel. 2 and the current position of the terminal 5 may be specified by specifying the position or section corresponding to the received address on the general operation panel 2 side. Alternatively, the terminal 5 may adopt another positioning method and acquire the position information of the terminal itself. For example, 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 an indoor positioning system that can not use the satellite radio waves of the positioning system using these satellites, pseudo-satellite GPS (Pseudolite), GPS repeater, IMES (Indoor Messaging System), wireless LAN positioning system, Bluetooth Low such as iBeacon and Eddystone You may employ | adopt the beacon transmission means by Energy (BLE) etc., the positioning system based on electronic signs, such as QR code (trademark) and an electronic tag, the positioning system using a sound wave signal, etc. When the terminal position information acquired in this way is given as position coordinates, the fire alarm unit 253 or the third residual determination unit of the general operation panel 2 that has received this information by the information receiving unit 251 By comparing with the map information, the section or floor where the terminal 5 is located may be specified.

2-7. Modification 7
The support server 4 receives the address of the fire detector D superimposed on the beacon signal as the position information from the terminal 5. If the building has an entrance / exit management system, the entrance / exit management is performed. You may make it manage the positional information on the terminal 5 based on the entrance / exit information acquired from a system.

  Alternatively, the location information of the terminal 5 is not acquired via the support server 4, and the location information fixedly set for each resident is associated with the terminal ID of the resident's terminal 5 and the terminal location database 423. You may make it store in. Here, the position information fixedly set for each person in the building is, for example, information indicating the position of the section where the person in the building is staying everyday. When the location information of the resident person is fixedly set, the terminal to which the fire alarm message is transmitted does not necessarily need to be portable. That is, the terminal according to the present invention may be a stationary computer device that is routinely used by a person in the building.

2-8. Modification 8
The normal number of people in the building 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. These detection results may be used, or both detection results may be used.

  In addition, the detection of the residual is performed by detecting the first residual determination unit 256 based on the call from the microphone-equipped speaker 6, 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 detection result may be used. Of these, in the case of using one detection result, the completion of evacuation of the section can be confirmed when the residual person detection operation is performed after completion of the evacuation guidance and no residual person is detected.

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

2-10. Modification 10
The planar map displayed on the 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 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 section map in accordance with the displayed map. Moreover, the type of the map displayed on the map screen may be arbitrarily switched.

2-11. Modification 11
In the operation when the fire 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 shutter S ′, Alternatively, the microphone-equipped speaker 6 closest to the fire-proof shutter S ′ is specified. However, the speaker with microphone 6 previously associated with the fire-proof shutter S ′ may be specified in the database.

2-12. Modification 12
The fire alarm message to be output from the microphone-equipped speaker 6 is determined by the general operation panel 2, but the emergency broadcast facility is based on the fire information from the fire receiver 1 or the general operation panel 2. 3 may be determined. Therefore, the emergency broadcast facility 3 further includes an area of the facility database 341 that stores 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 facility 3 receives the fire information specifying the fire floor, the broadcast control unit 352 refers to the facility 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 control information associated with the fire alarm message specified for each address of the speaker 6 with microphone from the communication unit 31. The microphone-equipped speaker 6 that has received the control information outputs a fire alarm message that expresses the fire floor in a relative positional relationship with the floor on which the fire floor is installed.

  Further, the facility database 341 also stores the address and installation location of the fire shutter S ′ in association with each other. When the information reception unit 351 of the emergency broadcast facility 3 receives the address of the fire shutter S ′ that has been activated from the fire receiver 1 or the general operation panel 2, the broadcast control unit 352 is closest to the fire 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 as voice.

  The equipment database 341 may perform mirroring that acquires and stores 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 with reference 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 be specified. Therefore, the support server 4 is provided with an equipment database (not shown) that stores the beacon address in association with the installation location specified by the floor and the section. Based on the terminal position information acquired from the terminal 5, the support server 4 can identify the floor and section where the terminal 5 exists by referring to the facility database provided by the support server 4.

  When the terminal position information is coordinate information based on various positioning systems, a map information database (not shown) for storing the sections and floors in the building as coordinate information is provided instead of the equipment database. In this case, the support server 4 may compare the terminal position information acquired from the terminal 5 with the information of the map information database provided by itself, and specify the floor and the section indicated by the coordinate information of the terminal 5. it can.

2-14. Modification 14
The support server 4 may further include a residual database (not shown) that stores residual information for each section so that the residual information can be viewed from the terminal 5. For example, the residual database may be mirrored by acquiring and storing 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 that allows browsing of residual information using a browser provided in the terminal 5.

  Further, the support server 4 stores the image information captured by the IP camera 7, the sound information collected by the speaker 6 with a microphone, and the information output by the sound in the storage unit 42 as a log in addition to the residual information. Also good. Moreover, you may enable it to access and confirm the said log from the terminal 5 similarly to the said remaining person information.

2-15. Modification 15
In the above-described embodiment, the highly urgent floor has been described as a floor relatively close to the fire floor, but is not limited to this. For example, as the highly urgent floor, priority is given to the upper floor side from the fire floor. Alternatively, the fire floor can be divided into an upper floor and a lower floor, and a floor close to the fire floor on the upper floor side can be given priority.

  For example, it can be determined appropriately for each building according to a fire fighting plan formulated according to the structure of the building. When a building is composed of multiple buildings, for example, twin towers, and is connected by a crossing corridor, etc., and is accessible for evacuation, the floor connected to the floor closer to the connected floor than the fire floor or away from the fire floor Because the floor where there is can be judged that the difficulty of evacuation is low, the urgency may be reduced. Conversely, if a fire floor exists in the middle of the route to the connected floor, which is an evacuation route, it is desirable to increase urgency. Thus, the urgency level of the floor can be determined according to the relative positional relationship between the fire floor and the connected floor serving as an evacuation route for each floor.

2-16. Modification 16
In the above-described embodiment, the target for outputting a warning message from the nearby speaker 6 with a microphone at the time of operation is described as the fire shutter S ′ as the automatic closing device, but is not limited thereto. If an automatically operating device poses a danger to a person, that device is the target for outputting a warning message. For example, even if it is an automatic opening device or an automatic closing device other than the fire shutter S ′, a warning message is output if there is a danger. The same applies when there is a danger when the fire extinguisher automatically operates, for example, when there is a risk of suffocation, lack of oxygen, gas poisoning, etc. due to the fire extinguishing gas.
