Description

[Technical field]

[0001] The present invention relates to a technique for detecting the occurrence of a fire and issuing an alarm. [Background technology]

[0002] There is known a fire alarm system that has multiple fire alarms arranged within a monitored area, and when any of the fire alarms detects a fire, the fire alarm that detected the fire (hereinafter referred to as the "fire alarm at the source of the fire") emits a sound to notify nearby people (people and devices such as robots capable of sound recognition) of the fire (hereinafter referred to as "alarming") and also sends a signal to other fire alarms (hereinafter referred to as "fire alarms other than the source of the fire"), so that any fire alarms other than the source of the fire that receive the signal will also sound an alarm.

[0003] An example of a document that describes the above-mentioned linked fire alarm system is Patent Document 1. Patent Document 1 proposes a mechanism in which each of a plurality of fire alarms provided in a fire alarm system stores history information of the other fire alarms in addition to its own history information, so that even if one of the fire alarms is damaged by a fire or the like and loses its stored history information, the history information of that fire alarm can be retrieved from the other fire alarms.

[0004] [Patent Document 1] JP 2019-61316 A Summary of the Invention [Problem to be solved by the invention]

[0005] In some fire alarm systems equipped with multiple fire alarms that sound in conjunction with each other, the fire alarm at the source of the fire will sound "Fire," while fire alarms other than the source of the fire will sound "Fire at number XX," thereby informing people in the vicinity of the source of the fire. People who hear these sounds can know that the source of the fire is near the location of the fire alarm sounding "Fire," and that the source of the fire is near the location of the fire alarm indicated by the "XX number" sound sounded by the fire alarms other than the source of the fire.

[0006] However, there are cases where people who hear the sound from a fire alarm cannot distinguish between the sounds from multiple fire alarms, or cannot identify the location of the fire alarm from the information indicated by the sound such as "number XX." In such cases, people who are within or near the monitored area cannot identify the location of the fire.

[0007] In consideration of the above circumstances, the present invention aims to provide a fire alarm system equipped with multiple fire alarms that work in conjunction with each other to sound an alarm, which enables people within or near the monitored area of ​​the fire alarm system to easily identify the location of the source of a fire. [Means for solving the problem]

[0008] The present invention provides a fire alarm comprising a detection means for detecting a fire, a transmission means for transmitting an instruction signal to other fire alarms to notify them of a fire, a receiving means for receiving the instruction signal transmitted from the other fire alarms, an acquisition means for acquiring sound data indicating a sound corresponding to each of one or more other fire alarms, a storage means for storing the sound data acquired by the acquisition means, and a sound generation means for generating a sound indicated by the sound data corresponding to the other fire alarm stored in the storage means when the receiving means receives the instruction signal from the other fire alarm. Effect of the Invention

[0009] According to the fire alarm of the present invention, in a fire alarm system having a plurality of fire alarms which are linked together and issue an alarm by voice, People nearby can easily identify the location of the fire. [Brief description of the drawings]

[0011] FIG. 1 is a diagram showing an example of the configuration of a fire alarm system 1 according to one embodiment of the present invention. The fire alarm system 1 comprises a plurality of fire alarms, exemplified by fire alarms 11 to 14. In the following description, the number of fire alarms provided in the fire alarm system 1 is assumed to be four, but the number of fire alarms provided in the fire alarm system 1 may be any number as long as it is two or more. Furthermore, in the following description, when the fire alarms 11 to 14 are not to be distinguished from one another, they will be collectively referred to as "fire alarm 10."

[0012] The fire alarm devices 11-14 are connected to each other wirelessly or by wire and can communicate with each other. The fire alarm system 1 is installed in a building 9. The building may be, for example, an ordinary house, an apartment complex, a hotel, an office building, or a commercial facility. Each of the fire alarm devices 10 monitors the occurrence of a fire in the space in which it is installed. That is, the monitoring areas of the fire alarm devices 11-14 are space R1, space R2, space R3, and space R4, respectively, as shown in FIG. 1.

[0013] 2 is a diagram showing an example of the configuration of the fire alarm 10. The fire alarm 10 comprises a detection means 101, a transmission means 102, a reception means 103, a sound generation means 104, a storage means 105, and an acquisition means 106.

[0014] The detection means 101 includes a sensor and detects a fire. The sensor included in the detection means 101 may be, for example, a smoke sensor that detects smoke, a heat sensor that detects heat above a predetermined temperature, a flame sensor that detects flames from a captured image, etc. Note that the types of sensors included in the detection means 101 are not limited to these. Furthermore, the detection means 101 may include two or more different types of sensors.

[0015] When the detection means 101 of the fire alarm (e.g., fire alarm 11) at the source of the fire detects a fire, the transmission means 102 transmits an instruction signal to instruct the other fire alarms 10 (e.g., fire alarms 12 to 14) to notify them of the occurrence of a fire.

[0016] When another fire alarm 10 (for example, the fire alarm 11) that has detected a fire transmits an instruction signal instructing notification of the occurrence of a fire, the receiving means 103 receives the instruction signal.

[0017] The sound generating means 104 includes a speaker, and when the detection means 101 detects a fire in the fire alarm at the fire source (for example, the fire alarm 11), the sound generating means 104 repeatedly generates a sound "There's a fire" to notify (issue an alert) the occurrence of a fire to people in or near the monitored area. Also, when the receiving means 103 receives an instruction signal from the fire alarm 10 at the fire source (for example, the fire alarm 11), the sound generating means 104 repeatedly generates a sound "There's a fire at XX" to notify (issue an alert) the occurrence of a fire to people in or near the monitored area. Here, "XX" is a word freely set by the user as a word indicating the installation location of the fire alarm 10 at the fire source (for example, the fire alarm 11). A method for the user to set this word "XX" will be described later.

[0018] The storage means 105 stores sound data (e.g., sound waveform data) representing the sound produced by the sound production means 104. The storage means 105 stores preset sound data S1 representing the sound produced by producing fixed phrases such as "There's a fire," "There's a fire at...," and "There's a fire at... and...," and sound data S2 representing the sound produced by reading out words indicating the installation locations of each of the multiple fire alarms 10 (words freely set by the user as described above).

[0019] 3 is a diagram showing the configuration of a data table T that stores sound data S2 corresponding to each fire alarm 10, which is stored in the storage means 105. The data table T stores, in association with a device ID (Identifier) ​​that identifies each fire alarm 10, the sound data S2 corresponding to the fire alarm 10 identified by that device ID.

[0020] In the example of Figure 3, for example, the sound data of the fire alarm 10 identified by the device ID "0254" represents a voice reading out the words "living room on the first floor," and the sound data of the fire alarm 10 identified by the device ID "1578" represents a voice reading out the words "Taro's room on the second floor."

[0021] The acquiring means 106 acquires the data table T in which the sound data S2 is stored from the external device. In this embodiment, the acquiring means 106 includes a USB (Universal Serial Bus) terminal (for example, a terminal called "USB Type-C"), and acquires the data table T output from the terminal device used by the user via the USB terminal. The data table T acquired by the acquiring means 106 is stored in the storage means 105.

[0022] In this embodiment, the data table T is generated by the data processing system in response to an operation performed by a user using a terminal device.

[0023] The data processing system 2 includes a terminal device 21 and a server device 22. The terminal device 21 and the server device 22 are capable of data communication via a communication network N.

[0024] The terminal device 21 is realized by, for example, a general computer equipped with a communication interface, a data input / output interface equipped with a USB terminal, a display, an input device such as a keyboard, and a camera, executing a program for the terminal device 21 according to this embodiment. The keyboard and the like equipped in the terminal device 21 may be built into the main body of the terminal device 21, or may be connected to the main body of the terminal device 21 by wire or wirelessly as an external device. Hereinafter, the hardware of the terminal device 21 is assumed to be, for example, a smartphone that is a small tablet-type PC (Personal Computer) equipped with a touch screen and a camera and capable of mobile communication and making and receiving phone calls.

[0025] The server device 22 is realized, for example, by a general computer equipped with a communication interface executing a program for the server device 22 according to this embodiment.

[0026] Fig. 5 is a diagram showing the functional configuration of the terminal device 21 and the server device 22. That is, the computer for the terminal device 21 and the computer for the server device 22 each function as a device having the components shown in Fig. 5 by executing a program.

[0027] The terminal device 21 includes, as functional components, a storage unit 210, an identification data acquisition unit 211, a text data acquisition unit 212, a sound data acquisition unit 213, and an output unit 214.

[0028] The storage means 210 stores various data. The identification data acquisition means 211 acquires identification data, i.e., a device ID, that identifies each fire alarm 10. In this embodiment, the identification data acquisition means 211 captures an image of a two-dimensional barcode (e.g., a QR code (registered trademark)) that is affixed to the housing of the fire alarm 10 with a camera, and decodes the captured two-dimensional barcode to acquire a device ID that identifies the fire alarm 10.

[0029] The text data acquisition means 212 acquires text data selected or input by the user via the touch screen.

[0030] The sound data acquisition means 213 acquires sound data S2 indicating a voice reading out text (words) indicated by the text data acquired by the text data acquisition means 212. In this embodiment, the sound data acquisition means 213 acquires the sound data S2 by transmitting the text data acquired by the text data acquisition means 212 to the server device 22 and receiving sound data transmitted from the server device 22 as a response thereto. For this reason, the sound data acquisition means 213 includes a transmission means 2131 that transmits the text data to the server device 22 and a reception means 2132 that receives the sound data from the server device 22.

[0031] FIG. 6 is a diagram showing a screen displayed by the terminal device 21 for acquiring the device ID of the fire alarm 10 and acquiring the sound data S2 (hereinafter referred to as the "installation location sound setting screen").

[0032] The installation location audio setting screen includes an area A1 which displays an image captured by the camera of the terminal device 21, an area A2 which displays the device ID obtained by decoding a two-dimensional barcode that is affixed to the fire alarm 10 when the camera captures the image, an area A3 which displays a selection of words indicating the floor number of the building (e.g., "1st floor", "2nd floor", etc.), an area A4 which displays a selection of words indicating the type of room (e.g., "living room", "kitchen", etc.), an area A5 which displays a text box which allows the user to freely input and edit text, and an area A6 which displays a group of buttons.

[0033] With the terminal device 21 displaying the installation location audio setting screen, the user adjusts the direction and position of the terminal device 21 so that the two-dimensional barcode affixed to the fire alarm 10 is displayed in area A1. When the two-dimensional barcode affixed to the fire alarm 10 is photographed by the camera of the terminal device 21 and displayed in area A1, the identification data acquisition means 211 decodes the two-dimensional barcode and acquires the device ID of the fire alarm 10. The device ID acquired in this way is displayed in area A2.

[0034] Next, the user operates areas A3 to A5 to input words indicating the installation location of the fire alarm 10. For example, when a two-dimensional barcode attached to a fire alarm 10 whose installation location is the living room on the first floor is photographed, the user selects "first floor" from the options displayed in area A3, and selects "living room" from the options displayed in area A4. In response to these selection operations, the words "living room on the first floor" are automatically input into the text box of area A5. The user can freely edit the words automatically input into area A5 as necessary. For example, when the user performs a touch operation on the text box of area A5 to achieve this, a virtual keyboard pops up.

[0035] The user can also directly input words into the text box in area A5 without selecting words from the options displayed in areas A3 and A4. For example, when a two-dimensional barcode attached to a fire alarm 10 installed in Taro's room on the second floor is photographed, the user inputs "Taro's room on the second floor" into the text box in area A5. In this case, a virtual keyboard is also popped up in response to, for example, a touch operation by the user on the text box in area A5.

[0036] When the user completes inputting the words indicating the installation location of the fire alarm 10 into the text box in area A5 by the above-mentioned selection or input operation, the user performs a touch operation on the "Setting" button in area A6. In response to this touch operation, the sound data acquisition means 213 transmits the text data input in area A5 to the server device 22, and receives the sound data S2 transmitted from the server device 22 as a response.

[0037] Next, the storage means 210 adds a new data record (data row) to the data table T, and stores in that data record the device ID displayed in area A2 and the sound data S2 received by the sound data acquisition means 213 from the server device 22.

[0038] When the user performs setting operations on the installation location audio setting screen described above for each of the multiple fire alarms 10 installed in the building 9, a data table T is prepared which stores and associates the device ID and sound data S2 for each of the multiple fire alarms 10.

[0039] The functional configuration of the terminal device 21 will be further described with reference to Fig. 5. The output means 214 outputs the data table T prepared as described above and stored in the storage means 210 to the fire alarm 10. In this embodiment, the output means 214 outputs the data table T via a data transmission cable (USB cable) connecting USB terminals to the fire alarm 10 to which the data transmission cable is connected.

[0040] The fire alarm 10 acquires the data table T output from the terminal device 21 connected via a USB cable, and stores it in the storage means 105.

[0041] When a user connects the terminal device 21 to each of the multiple fire alarm devices 10 in sequence via a USB cable, the data table T is transmitted from the terminal device 21 to each of the fire alarm devices 10, and the data table T is stored in the memory means 105 of each of the multiple fire alarm devices 10.

[0042] Next, a description will be given of the functional configuration of the server device 22. The server device 22 includes a receiving means 221, a voice synthesis means 222, and a transmitting means 223 as functional components.

[0043] The receiving means 221 receives text data transmitted from the terminal device 21. The voice synthesis means 222 generates, by a known voice synthesis technique, a voice reading out the text (words) indicated by the text data received by the receiving means 221. The transmitting means 223 transmits sound data indicating the voice generated by the voice synthesis means 222 to the terminal device 21.

[0044] Next, a description will be given of the operation of the fire alarm system 1 when any of the fire alarm devices 10 detects a fire. Below, as an example of the operation of the fire alarm system 1, a description will be given assuming that a fire F1 (see FIG. 1) has broken out in space R1, which is Taro's room on the second floor.

[0045] When a fire F1 breaks out in the space R1, the fire alarm 11 detects the breakout of the fire F1 by the detection means 101. Upon detecting the fire F1, the fire alarm 11 starts issuing an alert by repeatedly emitting the voice "There's a fire" represented by the sound data S1 stored in the storage means 105 by the sound generation means 104.

[0046] Furthermore, the fire alarm device 11 transmits an instruction signal to the fire alarm devices 12 to 14 by the transmission means 102. The instruction signal includes the device ID of the fire alarm device 11.

[0047] Each of the fire alarms 12-14 receives the instruction signal by the receiving means 103. Next, each of the fire alarms 12-14 reads out sound data S2 corresponding to the device ID included in the received instruction signal from the data table T stored in the storage means 105, and begins issuing an alarm by repeatedly emitting, by the sound generating means 104, a voice "There's a fire in Taro's room on the second floor," which is a combination of the voice "Taro's room on the second floor" indicated by the read sound data S2 and the voice "There's a fire in..." indicated by the sound data S1.

[0048] If a fire alarm 10 other than the fire alarm 11 (for example, the fire alarm 14 installed in the living room on the first floor) subsequently detects a fire due to the spread of the fire or the outbreak of a fire due to another cause, that fire alarm 10 (for example, the fire alarm 14) will transmit a command signal to the other fire alarms 10 (for example, the fire alarms 11-13). Then, instead of the voice that had been sounded up until then, the fire alarm 10 will repeatedly sound a voice such as "There is a fire in Taro's room on the second floor and in the living room on the first floor."

[0049] According to the above-described fire alarm system 1, in the event of a fire, a voice alert is issued reading out words indicating the location of the fire alarm 10 freely set by the user, so that people within or near the monitored area can easily recognize the source of the fire.

[0050] [Variations] The above-described embodiment is one embodiment of the present invention, and may be modified in various ways within the scope of the technical concept of the present invention. Examples of such modifications are shown below. Note that two or more of the modifications shown below may be combined as appropriate.

[0051] (1) In the above-described embodiment, the method adopted for the acquisition means 106 of the fire alarm 10 to acquire the data table T from an external device is to receive the data table T from the terminal device 21 by wired communication via a data transmission cable, such as a USB cable. The method for the acquisition means 106 of the fire alarm 10 to acquire the data table T from an external device is not limited to this and may be modified in various ways.

[0052] For example, the acquisition means 106 of the fire alarm 10 may be equipped with a reader that reads data from a recording medium such as an SD memory card, and the data table T may be acquired by reading the data table T using the reader from the recording medium that stores the data table T written out from the terminal device 21.

[0053] In addition, the acquisition means 106 of the fire alarm 10 may be equipped with a wireless communication interface that performs wireless communication according to a communication protocol such as Bluetooth (registered trademark) or WiFi Direct (registered trademark), and acquire the data table T by receiving the data table T transmitted by wireless communication from the terminal device 21 via the wireless communication interface.

[0054] In addition, the acquisition means 106 of the fire alarm 10 may be equipped with a wired communication interface that performs wired communication with an external device connected to a communication network via a LAN (Local Area Network) cable, and may acquire the data table T by receiving the data table T transmitted from the terminal device 21 via the communication network via the wired communication interface.

[0055] The acquisition means 106 of the fire alarm 10 may also include a microphone that picks up sound and an A / D (Analog to Digital) converter that generates sound data indicative of the sound picked up by the microphone, and may acquire sound data indicative of a voice uttered by the user as sound data S2. In this case, for example, the user performs a predetermined operation on each of the multiple fire alarms 10, puts the fire alarm 10 in a recording mode, and pronounces words indicative of the installation location of the fire alarm 10. The fire alarm 10 stores the sound data S2 indicative of the voice uttered by the user in a data table T stored in the storage means 105 of the own device in association with the device ID of the own device, and transmits the device ID of the own device and the sound data S2 to the other fire alarms 10 by the transmission means 102. When a fire alarm 10 receives a device ID and sound data S2 transmitted from another fire alarm 10 via a receiving means 103, the fire alarm 10 stores the device ID and sound data S2 in a data table T stored in the storage means 105 of the own device.

[0056] (2) In the above-described embodiment, the voice used to sound the fire alarm 10 at the source of the fire is "There's a fire," which does not include a voice indicating the location of the fire alarm 10 (its own device) at the source of the fire. However, as with fire alarms 10 other than the source of the fire, a voice including a voice indicating the location of the fire alarm 10 (its own device) at the source of the fire, such as "There's a fire in Taro's room on the second floor," may be used to sound the alarm.

[0057] (3) In the above-described embodiment, the voice used for issuing an alarm is a synthetic voice, but at least a part of the voice used for issuing an alarm may be a voice recorded from a voice uttered by the user. In this case, instead of inputting text in area A5 on the installation location voice setting screen, the user touches a "record" button (not shown in FIG. 6) included in area A6 on the installation location voice setting screen, and utters a voice indicating the installation location of the fire alarm 10 (for example, a voice saying "living room on the first floor") with the terminal device 21 in a recording mode. The terminal device 21 picks up the voice uttered by the user with a microphone, A / D-converts the sound data, and stores it in the data table T as sound data S2 in association with the device ID.

[0058] (4) In the above-described embodiment, the sound used for issuance of an alert is a combination of the sound represented by the default sound data S1 and the sound represented by the sound data S2 freely set by the user. Alternatively, only the sound represented by the sound data S2 freely set by the user may be used for issuance of an alert. In this case, the user may input text representing the entire sound to be used for issuance of an alert, such as "There's a fire in the living room on the first floor," into the text box in area A5 of the installation location sound setting screen (FIG. 6).

[0059] (5) In the above embodiment, each of the multiple fire alarm devices 10 acquires the data table T from the terminal device 21, but any one of the fire alarm devices 10 (e.g., fire alarm 11) may acquire the data table T from the terminal device 21, and the other fire alarm devices 10 (e.g., fire alarm 12-14) may acquire the data table T from another fire alarm device 10 that has already acquired the data table T (e.g., fire alarm 11 or a fire alarm 10 that has acquired the data table T from fire alarm 11). In this case, the data table T is transmitted from the transmitting means 102 of the fire alarm 10 that has acquired the data table T to the receiving means 103 of the fire alarm 10 that has not yet acquired the data table T.

[0060] (6) In the above-described embodiment, the method adopted for the identification data acquisition means 211 of the terminal device 21 to acquire the identification data (device ID) of the fire alarm 10 is that the terminal device 21 captures an image of a two-dimensional barcode attached, for example, to the housing of the fire alarm 10 and decodes the image. The method for the identification data acquisition means 211 of the terminal device 21 to acquire the identification data of the fire alarm 10 is not limited to this.

[0061] For example, any of the following methods may be adopted: the terminal device 21 photographs a one-dimensional barcode affixed to the housing of the fire alarm 10 and decodes it to obtain the identification data; the terminal device 21 photographs the identification data written in characters (including numbers, symbols, etc.) affixed to the housing of the fire alarm 10 and performs character recognition to obtain the identification data; the user reads the identification data written in characters (including numbers, symbols, etc.) affixed to the housing of the fire alarm 10 and manually enters it into the terminal device 21; or the terminal device 21 reads the identification data stored in an NFC (Near Field Communication) tag equipped on the fire alarm 10 using an NFC reader to obtain the identification data.

[0062] (7) A terminal device such as a smartphone carried by a user or a smart speaker (a speaker with an artificial intelligence assistant function that supports interactive voice operation) placed in the building 9 may pick up the sound emitted from the fire alarm 10 in the event of a fire and issue a voice corresponding to the picked-up sound to alert the user to a fire.

[0063] Fig. 7 is a diagram showing an example of the configuration of a fire alarm system 1 according to this modification. The fire alarm system 1 according to this modification includes a smartphone 15 carried by a user, in addition to the fire alarm devices 11-14 included in the fire alarm system 1 (Fig. 1) according to the embodiment described above.

[0064] Fig. 8 is a diagram showing the functional configuration of the smartphone 15 and the fire alarm 10 according to this modified example. That is, the computer, which is the hardware of the smartphone 15, executes a program for the smartphone 15 to function as a device having the components shown in Fig. 8.

[0065] The smartphone 15 includes, as functional components, a storage unit 150, a sound collection unit 151 (an example of a sound collection device), a decoding unit 152, a sound generation unit 153 (an example of a sound generation device), and a display unit 154.

[0066] The storage means 150 stores various data. The data stored in the storage means 150 includes sound data S1 indicating a voice of a predetermined fixed phrase, a data table T, and map data indicating the installation locations of each of the multiple fire alarms 10 in the building 9. Fig. 9 is a diagram illustrating an example of an image indicated by the map data. The image illustrated in Fig. 9 shows the rough positional relationship of each of the spaces R1 to R4, the device IDs of the fire alarms 10 arranged in each of these spaces R, and the names of the installation locations corresponding to these device IDs, i.e., the words that are meant by the voice indicated by the sound data S2.

[0067] The functional configuration of the smartphone 15 will be further described with reference to Fig. 8. The sound collection means 151 collects the sound emitted by the fire alarm 10 using a microphone, and generates sound data indicating the collected sound using an A / D converter.

[0068] In this modification, the fire alarm 10 repeatedly emits an audible sound such as "There's a fire at XX," in the same way as the fire alarm 10 according to the embodiment described above. In addition, in this modification, the fire alarm 10 emits an inaudible sound that encodes the device ID of the fire alarm 10 that is the source of the fire, between the sounds in the audible range.

[0069] Here, the inaudible sound refers to a frequency band that can be picked up by the microphone of the smartphone 15 but cannot be detected by normal human hearing. For example, the microphones of many smartphones can pick up sounds with frequencies up to about 22 kHz. Therefore, the frequency band of 20 kHz to 22 kHz that cannot be detected by normal human hearing can be used by the fire alarm 10 in this modified example to emit a sound indicating the device ID.

[0070] The sound with the coded device ID means a sound that expresses an analog signal obtained by converting the device ID by pitch or duration, such as the sound used by an analog modem for communication. The sound with the coded device ID may include a signal for error correction.

[0071] The sound collection means 151 of the smartphone 15 collects sounds in the inaudible range, and passes the sound data obtained by A / D conversion to the decoding means 152 .

[0072] The decoding means 152 decodes the sound indicated by the sound data delivered from the sound collection means 151, and obtains the device ID indicated by the sound.

[0073] When a device ID is acquired by decoding by the decoding means 152, the pronunciation means 153 reads out sound data S2 corresponding to the device ID from the data table T, and repeatedly pronounces a sound (e.g., "There's a fire in Taro's room on the second floor.") that is a combination of the sound indicated by the sound data S2 (e.g., a sound reading "Taro's room on the second floor") and the sound reading a standard phrase indicated by the sound data S1 (e.g., "There's a fire in...").

[0074] When a device ID is acquired by decoding by the decoding means 152, the display means 154 displays an image represented by the map data with an additional image indicating that the space R corresponding to the device ID is the space where the fire originated.

[0075] Fig. 10 is a diagram showing smartphone 15 in a state in which a fire is being reported. As shown in Fig. 10, smartphone 15 notifies the user of the occurrence of a fire and the location of the source of the fire by repeatedly uttering a voice such as "There is a fire in Taro's room on the second floor" and continuously displaying an image with a flame mark added in the space of the source of the fire.

[0076] According to this modified example, even if the sound emitted from the fire alarm 10 is difficult to hear, the user can easily recognize the location of the fire by the sound emitted from the nearby smartphone 15 and the image displayed on the smartphone 15.

[0077] In this modified example, instead of the fire alarm 10 uttering a sound indicating the device ID coded in the inaudible range, it may utter text data indicating the notification content coded in the inaudible range (for example, text data indicating the sentence "There's a fire in Taro's room on the second floor.").Then, the smartphone 15 may obtain the text data indicating the notification content by the decoding means 152, transmit the text data to the server device 22, receive sound data transmitted in response thereto, and utter a sound indicated by the received sound data by the sound pronunciation means 153.

[0078] In this modification, the fire alarm 10 may produce a voice that reads out the inaudible, uncoded device ID instead of producing a sound indicating the inaudible, coded device ID. The smartphone 15 may then perform voice recognition on the voice produced by the fire alarm 10 to obtain the device ID.

[0079] In addition, in this variant, the fire alarm 10 may not emit a sound indicating a coded device ID in the inaudible range, and the smartphone 15 may perform voice recognition of an audible sound emitted from the fire alarm 10 (for example, a voice saying "There's a fire in Taro's room on the second floor") and identify the device ID according to the content of the recognized voice.

[0080] In this modified example, the sound that the fire alarm 10 is supposed to produce in the inaudible range may be produced in the audible range. For example, instead of the fire alarm 10 producing the voice "There's a fire in Taro's room on the second floor," the fire alarm 10 may produce the voice in the audible range "There's a fire at number 1578." The smartphone 15 may then recognize the voice, obtain the device ID "1578," read out the sound data S2 corresponding to the device ID from the data table T, and produce the voice "There's a fire in Taro's room on the second floor."

[0081] Furthermore, in addition to or instead of the smartphone 15, a data processing device such as a smart speaker that is not carried by the user may report the occurrence of a fire and the source of the fire.

[0082] Furthermore, the smartphone 15 may notify the occurrence of a fire and its source by only one of sound and image display.

[0083] (8) In the above-described embodiment, some or all of the processing performed by the terminal device 21 may be performed by the server device 22 or another device capable of data communication with the terminal device 21. Also, in the above-described embodiment, some or all of the processing performed by the server device 22 may be performed by the terminal device 21 or another device capable of data communication with the server device 22. Therefore, the data processing system 2 may be composed of only the terminal device 21 that also has the functions of the server device 22, for example.

[0084] (9) In the above-described modification (7), a part of the processing performed by the smartphone 15 may be performed by another device capable of data communication with the smartphone 15. That is, the data processing system exemplified by the smartphone 15 may be configured by a single device such as the smartphone 15, or may be configured by multiple devices such as the smartphone 15 and a server device (e.g., a server device having the decoding means 152).
