DETAILED DESCRIPTION OF THE INVENTION

[0012] The automatic fire alarm system and disaster prevention system of the present disclosure will be described below with reference to the drawings. The present disclosure relates to an automatic fire alarm system and a disaster prevention system that collects rescue-related information using audio signals, and has a technical feature of being able to quickly determine whether there are people who have failed to escape in time and need rescue in the event of a fire by using such audio signals. Specific examples of the automatic fire alarm system and the disaster prevention system that have such technical features will be described in detail below.

[0013] Embodiment 1 1 is a configuration diagram of a disaster prevention system according to a first embodiment of the present disclosure. The disaster prevention system according to the first embodiment is configured to include an automatic fire alarm system 10, a cloud server 30, a network 40 such as the Internet, and a mobile terminal 50 carried by a user who receives rescue-related information.

[0014] The automatic fire alarm system 10 includes a plurality of fire detectors 11 installed in a fire prevention object (e.g., a building), a fire receiver 12 that collects information from the plurality of fire detectors 11 and outputs fire information, and an audio device 13 that outputs audio in response to an audio output command from the fire receiver 12.

[0015] The plurality of fire detectors 11 can transmit the detection of a fire as fire-related information to the fire receiver 12. In Fig. 1, three fire detectors 11(1) to 11(3) are shown as an example of the plurality of fire detectors 11, but other numbers of detectors may also be used.

[0016] In addition to the fire detector 11, other necessary terminal devices such as a control relay for smoke control equipment, a fire transmitter, and a gas leak detector can also be connected to the fire receiver 12.

[0017] The fire receiver 12 can communicate the fire-related information acquired from the fire detector 11 to the cloud server 30 via the Internet communication network 40. Furthermore, when the fire receiver 12 acquires the fire-related information from the fire detector 11, it can output a preset audio signal via a plurality of audio devices 13 installed at necessary locations within the fire prevention object.

[0018] As will be described in more detail below, the fire receiver 12 can output an audio signal via the audio device 13 to alert people in the vicinity of the audio device 13 that they can make an audio rescue request, and as a result, audio rescue requests can be quickly collected via the microphone installed in the fire detector 11.

[0019] 1, three audio devices 13(1) to 13(3) are shown as the multiple audio devices 13, but other numbers of devices may be used. Each of the multiple audio devices 13 is connected to an audio line for each device or for each floor, and the location where the broadcast is to be made can be specified by selecting an audio line using the fire control receiver 12.

[0020] In addition, fire detectors or fire transmitters that can output sound in response to a sound output command from the fire receiver 12 can also be used as the multiple sound devices 13.

[0021] As described above, each of the plurality of fire detectors 11 according to the first embodiment is equipped with a microphone and has an additional function of collecting vocal information in the vicinity of the installation location. Therefore, the fire detector 11 can transmit the detection of a fire to the fire receiver 12 as fire-related information, and can also transmit the collected vocal information to the fire receiver 12 as rescue-related information.

[0022] Address information for identifying each individual fire detector is assigned in advance to each of the plurality of fire detectors 11. Each of the plurality of fire detectors 11 can transmit fire-related information and rescue-related information to the fire receiver 12 as information including the address information assigned to that detector.

[0023] As a result, when the fire receiver 12 receives fire-related information, it can identify which fire detector 11 the information came from based on the address information contained in the information, and consequently identify the location from which the fire-related information was sent. Similarly, when the fire receiver 12 receives rescue-related information, it can identify which fire detector 11 collected the speech information based on the address information contained in the information, and consequently identify the location from which the rescue-related information was sent.

[0024] The automatic fire alarm system 10 according to the first embodiment having such a configuration can use audio signals to realize a function of collecting rescue-related information for quickly determining whether there are people who are in need of rescue and have been unable to escape in time for a fire. The function of collecting rescue-related information using audio signals will now be described in detail.

[0025] When the fire receiver 12 receives fire-related information indicating that a fire has been detected from any of the plurality of fire detectors 11, it can output a preset audio signal via the audio device 13. Specific examples of the preset audio signal include the following: "Are you experiencing any problems?" "If you need help, speak up"

[0026] The fire receiver 12 outputs such sound through a plurality of sound devices 13 installed at necessary locations within the fire prevention object, thereby alerting people around the sound devices 13 that they can request rescue by sound.

[0027] The fire receiver 12 can select the acoustic device 13 to output such an audio signal as follows: For example, the fire receiver 12 can output audio signals from all the acoustic devices 13. Alternatively, the fire receiver 12 can output audio signals only from the acoustic devices 13 located near the fire detector 11 that is the source of the fire-related information.

[0028] In addition, the fire receiver 12 can also perform sequence control so that audio signals are output preferentially from the audio device 13 located near the fire detector 11 that is the source of the fire-related information, and then audio signals are output sequentially from the other audio devices 13 with a time lag.

[0029] When the fire receiver 12 receives a voice signal corresponding to a voice request for rescue as rescue-related information via any of the fire detectors 11 in response to the output of the voice signal, it identifies the location from which the rescue request was made from the address information included in the rescue-related information.

[0030] In this way, the fire receiver 12 of this embodiment 1 works in conjunction with multiple fire detectors 11 and multiple audio devices 13 to prompt those in need of rescue to make a vocal request for rescue, and when a rescue request is received, it can identify the location from which the rescue request was made based on the vocal signal.

[0031] Therefore, if the location of the rescue request based on the vocal signal can be identified, the fire receiver 12 generates analysis request information including information about the vocal signal and the location of the rescue request, and transmits the generated analysis request information to the cloud server 30.

[0032] The cloud server 30 has a voice analysis program and analyzes the voice signal contained in the analysis request information received from the fire receiver 12 to extract words that are associated with an emergency situation contained in the voice signal.

[0033] The voice analysis program has registered keywords such as the following that are associated with emergencies: ·"help me" "HELP" "Failed to escape" "Injured person" "Person requiring assistance"

[0034] It should be noted that which of these keywords to use can be selected in advance by the manager of the fire prevention object or the like depending on the purpose.

[0035] If the cloud server 30 extracts keywords associated with an emergency from the vocal signal as a result of the analysis by the voice analysis program, the cloud server 30 generates emergency occurrence information by associating the extracted keywords with the sending location included in the analysis request information. Furthermore, the cloud server 30 transmits the generated emergency occurrence information to a mobile terminal 50 carried by a manager of the fire prevention object or the like via the Internet communication network 40.

[0036] 1 illustrates two mobile terminals 50a and 50b as examples of the multiple mobile terminals 50 that can communicate with the cloud server 30 via the internet communication network 40, but other numbers of mobile terminals are also possible. Also, instead of transmitting the emergency occurrence information to all mobile terminals 50, the cloud server 30 can select the mobile terminal 50 to be the transmission destination according to the "extracted keyword" or information about the "location of transmission" included in the emergency occurrence information.

[0037] To make this possible, the cloud server 30 has identification information for the mobile terminal 50, and if the private fire brigade has the mobile terminal 50, it also has information on the floor where the private fire brigade is normally located.

[0038] The mobile terminal 50 has installed therein application software for realizing a receiving function for receiving emergency information relating to a fire prevention object, and a display function for displaying on the screen display information corresponding to keywords and the sending location based on the received emergency information. When displaying fire information, it is also possible to display a floor plan of the building and the location of the fire.

[0039] In particular, this application software has a display function that can display information on the screen using icons corresponding to extracted keywords and a map display corresponding to the call location, in order to easily determine the content of the emergency occurrence information.

[0040] Examples of icon display include a wheelchair pictogram for "person requiring assistance" and a pictogram of an injured person being carried on a stretcher for "injured person." By storing the correspondence between the extracted keywords and icons in advance, the application software installed on the mobile terminal 50 can easily display icons corresponding to the extracted keywords.

[0041] Therefore, the mobile terminal 50 that receives the emergency occurrence information can display the "location of origin" as text information or map information as an analysis result by the application software, and can also display an icon corresponding to the "extracted word."

[0042] The owner of the mobile terminal 50 can quickly understand the details of the emergency situation from the displayed content and take appropriate action in response to the rescue request.

[0043] Next, a series of interlocking processes in the disaster prevention system according to the first embodiment will be described. Fig. 2 is a flow diagram showing interlocking operations by the components in the disaster prevention system according to the first embodiment of the present disclosure. Note that in Fig. 2, the fire detector 11, the sound device 13, and the mobile terminal 50 are depicted as one device that represents a plurality of devices.

[0044] In step S201, when the fire detector 11 detects that a fire has occurred, it transmits fire-related information to the fire receiver 12. Note that this fire-related information includes address information assigned to the fire detector 11 that detected the fire.

[0045] Next, in step S202, the fire receiver 12 receives fire-related information including address information from the fire detector 11, generates fire information that identifies the location of the fire, and, if necessary, transmits the fire information to the cloud server 30 and the mobile terminal 50.

[0046] In step S203, the fire receiver 12 outputs a voice output command to the audio device 13 to confirm by voice whether or not there is anyone needing rescue. The fire receiver 12 can select the audio device 13 to which the voice output command is to be sent depending on the location of the fire.

[0047] Next, in step S204, when the audio device 13 receives a voice output command from the fire receiver 12, it outputs a preset audio signal such as "Is there a problem?" or "If you need rescue, please speak up." As a result, it is possible to encourage people in need of rescue around the audio device 13 to vocally request rescue.

[0048] Next, in step S205, if the fire detector 11 receives a voice signal in response to the output of the audio signal in step S204, it generates rescue-related information including the voice signal and address information, and transmits the generated rescue-related information to the fire receiver 12.

[0049] Next, in step S206, the fire receiving device 12 identifies the location of the voice signal from the address information included in the received rescue-related information. Furthermore, the fire receiving device 12 generates information including the voice signal included in the received rescue-related information and information on the identified location of the voice signal, and transmits the information to the cloud server 30 as analysis request information.

[0050] Next, in step S207, the cloud server 30 analyzes the vocal signal contained in the received analysis request information using a voice analysis program, and if the vocal signal contains a keyword associated with an emergency, extracts the keyword.

[0051] Then, in step S208, if a keyword is extracted as a result of the voice analysis in step S207, the cloud server 30 generates emergency occurrence information that associates the extracted keyword with the location from which the voice signal was transmitted. Furthermore, the cloud server 30 transmits the generated emergency occurrence information to the mobile terminal 50 carried by the manager of the fire prevention object, etc.

[0052] Next, in step S209, the mobile terminal 50 displays the "location of origin" as text information or map information in response to the received emergency information based on the analysis results of the installed application software, and also displays an icon corresponding to the "extracted word."

[0053] The features of the disaster prevention system according to the present disclosure, which is capable of executing such a series of processes, can be summarized as follows. Feature 1: In the event of a fire, anyone trapped inside a fire-prevention building can quickly understand that they can request rescue by voice by listening to the voice announcement output from the audio device.

[0054] Feature 2: When the voice signal emitted by the rescue victim in response to the voice announcement is received by the fire receiver 12 via the fire detector 11, analysis request information can be sent to the cloud server 30.

[0055] Feature 3: When analysis request information is received by the cloud server 30, voice analysis is performed on the analysis request information to extract keywords associated with an emergency situation, and if keywords are extracted, emergency situation information can be sent to a mobile terminal 50 carried by the manager of the fire prevention object, etc.

[0056] Feature 4: When emergency information is received by the mobile terminal 50, the location and situation where the rescue request occurred can be displayed on the mobile terminal 50 using an icon or the like.

[0057] By having these features 1 to 4, in the event of a fire, the manager of the fire prevention object, etc. can effectively use voice to quickly and reliably grasp the emergency situation and rescue requests occurring at the fire site through the content displayed on the mobile terminal 50, and can take appropriate action in accordance with the rescue request.

[0058] Next, a specific example of the automatic fire alarm system 10 to which the disaster prevention system according to the present disclosure is applied will be described with reference to Fig. 3. Fig. 3 is an explanatory diagram showing a specific example of the automatic fire alarm system 10 to which the disaster prevention system according to the first embodiment of the present disclosure is applied. In Fig. 3, a four-story building is illustrated as an example of a fire prevention object.

[0059] Figure 3 also illustrates an example in which three fire detectors 11 are installed on each floor, one sound device 13 is installed on each floor, a fire receiver is installed on the first floor, and a fire breaks out near the fire detector 11 (33) installed on the third floor.

[0060] In this case, the fire receiver 12 receives fire-related information from the fire detector 11 (33) and detects that a fire has occurred at the location where the fire detector 11 (33) is installed. The fire receiver 12 then outputs an audio output command to the audio device 13 (3) installed on the third floor, where the fire occurred, and to the audio device 13 (4) installed on the fourth floor, which is the floor immediately above the third floor.

[0061] Furthermore, the fire receiver 12 then outputs, with a time lag, an audio output command to the audio device 13(2) installed on the second floor and the audio device 13(1) installed on the first floor. As a result, people on the first to fourth floors can make a voice request for rescue by listening to the audio announcements output from the audio devices 13 on each floor.

[0062] When the fire receiver 12 receives rescue-related information including a voice signal and address information via the fire detector 11, it identifies the source of the voice signal, generates analysis request information, and transmits the generated analysis request information to the cloud server 30. As a result, the fire receiver 12 can easily collect voice requests for rescue from people who need rescue and were unable to escape in time when a fire broke out, and can also cause the cloud server 30 to perform voice analysis.

[0063] The voice analysis program can also be implemented in the fire receiver 12 instead of in the cloud server 30. However, by installing the voice analysis program in the cloud server 30, it is possible to accumulate track records in various fields regarding the process of extracting keywords associated with an emergency, and by reflecting the learning results based on those records, it is possible to easily improve the voice analysis program.

[0064] As described above, the automatic fire alarm system according to the first embodiment is configured so that the fire detector, the fire receiver, and the audio device are linked together. As a result, when a fire occurs, audio signals can be effectively used to easily collect rescue requests at the fire site.

[0065] Furthermore, the disaster prevention system according to the present disclosure has a configuration in which the automatic fire alarm system, the cloud server, and the mobile terminal are linked via a network. As a result, rescue requests at the fire site can be easily collected by effectively using audio signals, and information about people who were unable to escape and need rescue can be quickly transmitted to the manager of the fire prevention object, etc., based on the analysis results of the audio signals.
