DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] (1) Overview Each drawing described in the following embodiments is a schematic drawing, and the size and thickness ratios of each component in each drawing do not necessarily reflect the actual dimensional ratios.

[0015] A detector 1 according to this embodiment detects the occurrence of an event that is a target for disaster prevention. A detection system 100 according to this embodiment includes a plurality of detectors 1, as shown in Fig. 1. A detector management system 200 according to this embodiment includes the detection system 100 and an external terminal 5 that manages the plurality of detectors 1, as shown in Fig. 1.

[0016] Here, as an example, it is assumed that the event that is the target of disaster prevention measures is a fire. In other words, it is assumed that the detector 1 is a fire detector. In particular, it is assumed that the detector 1 is a residential fire alarm (hereinafter, may be simply referred to as a residential alarm) that has a detection function for detecting the occurrence of a fire and an alarm function for notifying when a fire is detected. The detector 1 outputs a sound such as an alarm sound when a fire occurs. However, the event that is the target of disaster prevention measures is not limited to a fire, and may be a flood, an earthquake, etc. Furthermore, the event that is the target of disaster prevention measures may be a gas leak, or the generation of CO (carbon monoxide) due to incomplete combustion, etc.

[0017] The detector management system 200 is applied to, for example, a facility 7 (see FIG. 2). Specifically, the multiple detectors 1 are installed on a ceiling, a wall, or the like in a space within the facility 7 where the detectors are to be installed. In this embodiment, the multiple detectors 1 are installed in spaces E1 to E5 within the facility 7, respectively, as shown in FIG. 2. The external terminal 5 of the detector management system 200 is, for example, a controller for a home energy management system (HEMS) installed within the facility 7.

[0018] As described above, it is assumed that the detector 1 is, as an example, a residential alarm device, and the facility 7 is a detached house. However, the facility 7 may be an apartment building. Furthermore, the facility 7 is not limited to a house, and may be a non-house, such as an office building, a theater, a movie theater, a public hall, an amusement park, a complex, a restaurant, a department store, a school, a hotel, an inn, a hospital, a nursing home, a kindergarten, a library, a museum, an art gallery, an underground shopping mall, a station, an airport, etc.

[0019] Here, in this embodiment, as shown in FIG. 1, the detector 1 includes a storage unit H1 that stores location information related to at least an installation location L1 (see FIG. 2) where the detector 1 is installed. In the example of FIG. 2, the installation location L1 corresponds to any one of the spaces E1 to E5. Here, the storage unit H1 corresponds to a storage unit 20 that stores location information as data. Specifically, the storage unit H1 is composed of a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), and the like. However, the storage unit H1 is not limited to being composed of the above devices. The storage unit H1 may store location information by switching the on / off state of a contact such as a DIP switch or a rotary switch.

[0020] In the following, as an example, when the detector 1 functions as a child device, the location information held by the holding unit H1 is information related only to the installation location L1 of the detector 1 itself (own device). In other words, the holding unit H1 of the child device holds only location information related to the installation location L1 of the own device, and does not hold location information related to the installation locations L1 of other detectors 1 (other devices). On the other hand, when the detector 1 functions as a parent device, the detector 1 holds location information related to the installation location L1 of the own device as well as location information related to the installation locations L1 of other devices.

[0021] According to this configuration, the storage unit H1 stores the location information. Therefore, for example, the detector 1 itself issues a notification according to the location information, or another device issues a notification according to the location information of the detector 1, thereby improving the recognition of the location of an event (for example, a fire) that is a target of disaster prevention.

[0022] (2) Details (2.1) Overall Structure The overall configuration of the detector 1, detection system 100, and detector management system 200 according to this embodiment will be described in detail below. Here, the detector 1 is a battery-powered home alarm, as an example. However, the detector 1 may be electrically connected to an external power source (e.g., a commercial power system) and may be driven by converting AC power (e.g., effective value 100 V) supplied from the external power source into DC power.

[0023] As shown in Figs. 1 and 2, the detection system 100 includes a plurality of detectors 1 (five in the illustrated example). The plurality of detectors 1 are so-called linked home alarm devices, and are configured to issue an alarm sound in conjunction with the other detectors 1 (together with the other detectors 1) when any of the detectors 1 detects a fire. In this embodiment, a network capable of communication is formed between the plurality of detectors 1. Here, of the five detectors 1, the detector 1A functions as a parent device, and the other detectors 1B to 1E function as child devices, and communication is possible between the parent device and the child devices (see Fig. 2). Hereinafter, the four detectors 1B to 1E functioning as child devices will be referred to as child devices 101 (first detector), and the detector 1A functioning as a parent device will be referred to as parent device 102 (second detector).

[0024] In the following, as shown in the example of FIG. 2, it is assumed that the multiple detectors 1 are all installed on the ceiling surface of each room or staircase in a facility 7 (detached house). Specifically, detector 1A is placed in space E1, detector 1B in space E2, detector 1C in space E3, detector 1D in space E4, and detector 1E in space E5. Space E1 is, for example, a living room. Space E2 is, for example, a bedroom. Space E3 is, for example, a staircase. Space E4 is, for example, a child's room. Space E5 is, for example, a kitchen. The example of FIG. 2 shows a state in which a fire has broken out in space E1, which is a living room. Details of each detector 1 will be explained in the section "(2.2) Detectors" later.

[0025] As shown in Fig. 1, the detector management system 200 includes a detection system 100 and an external terminal 5. The detector management system 200 may further include an information terminal 6 and an external server 8 (see Fig. 3). The external terminal 5 is configured to manage a plurality of detectors 1. In the example of Fig. 2, the external terminal 5 is installed next to the stairs on the first floor in space E3. Details of the external terminal 5, information terminal 6 and external server 8 will be explained later in the section "(2.3) External Terminal".

[0026] (2.2) Detector (2.2.1) Parent unit (second detector) First, among the multiple detectors 1, the configuration of the master unit 102 (detector 1A) will be described.

[0027] The master unit 102 is configured to detect the occurrence of an event that is the subject of disaster prevention (here, a fire). The master unit 102 has a detection function for detecting the occurrence of a fire in the facility 7, and an alarm function for issuing an alarm when the occurrence of a fire in the facility 7 is detected. As shown in FIG. 1, the master unit 102 includes a control unit 10, a memory unit 20, a first communication unit 21, a second communication unit 22, a battery 23, a detection unit 3, and an alarm unit 4. In addition to the above, the master unit 102 further includes circuit modules such as an audio circuit and a lighting circuit. The battery 23 is, for example, a lithium battery, and the master unit 102 operates using power supplied from the battery 23.

[0028] The parent unit 102 also includes a storage unit H1 that stores location information related to the installation location L1 where at least the detector 1 is installed. As described above, the storage unit H1 corresponds to the memory unit 20, for example. The storage unit H1 of the parent unit 102 stores not only location information related to the installation location L1 where the parent unit 102 is installed, but also location information related to the installation locations L1 of each of the four child units 101.

[0029] The control unit 10 has, for example, a computer system having a processor and a memory. The processor executes a program stored in the memory, causing the computer system to function as the control unit 10. The program executed by the processor is pre-recorded in the memory of the computer system here, but may be provided by being recorded on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet.

[0030] The detection unit 3 has a function (detection function) of detecting information related to a fire that is the target of an alarm sound. Here, the detection unit 3 is, as an example, a photoelectric sensor that detects smoke. Therefore, the above-mentioned information related to a fire includes, for example, information related to smoke. However, the detection unit 3 is not limited to a photoelectric sensor, and may be, for example, a constant temperature sensor that detects heat. As shown in FIG. 1, the detection unit 3 has, for example, a light emitting unit 31 such as an LED (Light Emitting Diode) and a light receiving unit 32 such as a photodiode. The light emitting unit 31 and the light receiving unit 32 are arranged in the labyrinth of the housing of the device so that the light receiving surface of the light receiving unit 32 is off the optical axis of the light emitted by the light emitting unit 31. When a fire occurs, smoke can be introduced into the labyrinth through a hole provided in the housing.

[0031] When there is no smoke in the labyrinth of the housing, almost no light emitted by the light-emitting unit 31 reaches the light-receiving surface of the light-receiving unit 32. On the other hand, when smoke is present in the labyrinth of the housing, the light emitted by the light-emitting unit 31 is scattered by the smoke, and some of the scattered light reaches the light-receiving surface of the light-receiving unit 32. In other words, the detection unit 3 receives the light emitted by the light-emitting unit 31 scattered by the smoke at the light-receiving unit 32. The detection unit 3 outputs an electrical signal (detection signal) indicating a voltage level corresponding to the amount of light received by the light-receiving unit 32 to the control unit 10.

[0032] 1, the notification unit 4 has a display unit 41 and an audio unit 42. The notification unit 4 has a function (notification function) of notifying the occurrence of a fire when the occurrence of a fire in the facility 7 is detected. In this embodiment, the notification unit 4 performs notification by light and sound.

[0033] The acoustic unit 42 has a function of notifying the occurrence of a fire. The acoustic unit 42 outputs a sound (sound wave). When the control unit 10 determines that a fire has occurred in the facility 7, the acoustic unit 42 outputs an alarm sound to notify the occurrence of the fire.

[0034] The acoustic unit 42 is composed of a speaker that converts an electrical signal into sound. The speaker has a diaphragm, and emits an alarm sound by mechanically vibrating the diaphragm in accordance with an electrical signal. The acoustic unit 42 outputs an alarm sound (e.g., a beep sound) under the control of the control unit 10. It is preferable that the acoustic unit 42 outputs the alarm sound by changing the volume (sound pressure level) of the alarm sound. The alarm sound may include, for example, a sweep sound that sweeps from a low tone to a high tone.

[0035] However, the alarm sound of this embodiment is output under the control of the control unit 10 with at least location information related to the installation location L1 of the detector 1 that detected the fire included in the voice message. In other words, when the notification unit 4 of this embodiment detects the occurrence of a fire (event), it issues a notification according to the location information of the detector 1 that detected the fire. The "location information" related to the installation location L1 is name information indicating the name of the installation location L1 (such as "living room", "stairs", "bedroom", "children's room", and "kitchen"), or code information identifying the installation location L1 (such as "A1", "A2", and "A3"). Here, the alarm sound is output with the name information included in the voice message. The alarm sound is composed of a sweep sound and a voice message that follows the sweep sound.

[0036] The installation location L1 of the master unit 102 is the living room (space E1). If the occurrence of a fire is detected by the master unit 102, the audio section 42 of the master unit 102 outputs an audio message such as "There's a fire in the living room. There's a fire in the living room." In this case, with regard to the linked operation of alarms between multiple detectors 1, the link source (source of the fire) of the alarm is the master unit 102. Other detectors 1 as link destinations also output audio messages such as "There's a fire in the living room. There's a fire in the living room." However, the detector 1 at the source of the fire may output an audio message such as "There's a fire. There's a fire." In other words, the detector 1 at the source of the fire may output an audio message that omits location information.

[0037] When the detector 1 receives an operation input (push operation) from the outside using a push button type operation unit or the like during an alarm (when an alarm sound is being issued), the audio unit 42 stops outputting the alarm sound.

[0038] The display unit 41 has a function of notifying the occurrence of a fire. The display unit 41 is an operating light having a red LED 410 as a light source. The display unit 41 is normally turned off (during fire monitoring), and starts blinking (or lighting) when the control unit 10 determines that a fire has occurred. This blinking stops under the control of the control unit 10 when the alarm sound stops being issued.

[0039] As described above, the memory unit 20 corresponds to the retention unit H1, and is configured with a device selected from ROM, RAM, EEPROM, etc. The memory unit 20 stores a unique identifier (identification information) assigned to itself (its own device). The "identifier (identification information)" is the IP address, Mac address, name, etc. of the detector 1. The memory unit 20 also stores warning message data related to a voice message to be output as a warning sound. The memory unit 20 may be a memory of the control unit 10.

[0040] In particular, the memory unit 20 (holding unit H1) of the parent device 102 stores location information related to the installation location L1 where the parent device is installed and location information related to the installation locations L1 where other detectors 1 are installed, as described above. Here, the memory unit 20 stores multiple pieces of code information identifying the installation locations L1 of multiple detectors 1 including the parent device as location information in association with the identifiers of the corresponding detectors 1. The location information is, for example, one of five pieces of code information "A1" to "A5".

[0041] The storage unit 20 (holding unit H1) further holds correspondence information. The "correspondence information" is information in which name information indicating the names of a plurality of installation locations L1 is associated with a plurality of code information identifying the plurality of installation locations L1. Specifically, the holding unit H1 holds information in which, for example, name information "living room" is associated with a code "A1". Similarly, the holding unit H1 holds information in which name information "bedroom" is associated with a code "A2", name information "staircase" is associated with a code "A3", name information "children's room" is associated with a code "A4", and name information "kitchen" is associated with a code "A5". The code information is not particularly limited, but it is desirable that the data length of the code information be smaller than the data length of the name information.

[0042] The first communication unit 21 has a communication interface for wirelessly communicating with other detectors 1 using radio waves in a first frequency band. The first frequency band is, for example, the 420 MHz band. The first communication unit 21 receives detection information from other detectors 1. Furthermore, when the first communication unit 21 receives detection information from one detector 1 (e.g., detector 1B), it transmits an alarm instruction to the other detectors 1 (e.g., detectors 1C to 1E).

[0043] The "detection information" is information notifying that a fire has been detected in the facility 7, and may include, for example, location information (code information), an identifier, and a detection result (whether or not a fire has occurred).

[0044] The second communication unit 22 has a communication interface for performing wireless communication with the external terminal 5 using radio waves in a second frequency band different from the first frequency band. The second frequency band is, for example, a 920 MHz band. For example, when the second communication unit 22 detects a fire, the second communication unit 22 transmits detection information of the own device to the external terminal 5. When the first communication unit 21 receives detection information from any of the four child devices 101 (detectors 1B to 1E), the second communication unit 22 transmits the detection information to the external terminal 5.

[0045] The control unit 10 determines whether or not a fire has occurred based on the detection signal output by the detection unit 3. For example, the control unit 10 determines that a fire has occurred when the voltage level indicated by the detection signal is equal to or higher than a predetermined threshold value.

[0046] 1, the control unit 10 has a detection output unit 11, a setting output unit 12, a switching unit 13, and a setting unit 14. In other words, the control unit 10 has a function as the detection output unit 11, a function as the setting output unit 12, a function as the switching unit 13, and a function as the setting unit 14. The setting output unit 12, the switching unit 13, and the setting unit 14 will be described in detail later in the section "(2.5) Setting of location information."

[0047] When the detection output unit 11 detects the occurrence of a fire (event), the detection output unit 11 outputs at least location information to an output destination so that the output destination makes a report according to the location information of the detection unit. The output destinations here include the four child devices 101 and the external terminal 5. In other words, the detection output unit 11 outputs detection information including the code information "A1" of the detection unit to the four child devices (detectors 1B to 1E) so that a voice message such as "There's a fire in the living room. There's a fire in the living room" is output from the four child devices 101. The detection output unit 11 also outputs the detection information to the external terminal 5.

[0048] Specifically, when the device itself detects the occurrence of a fire, the detection output unit 11 transmits information informing of the fire detection, in other words, the detection information of the device itself, to the external terminal 5 via the second communication unit 22. Furthermore, when the device itself detects the occurrence of a fire, the detection output unit 11 transmits the detection information of the device itself to the four child devices 101 via the first communication unit 21 in order to act as a linking source and link the issuance of an alert.

[0049] When the control unit 10 detects the outbreak of a fire, it starts outputting an alarm sound from the audio unit 42. For example, when the control unit 10 causes the audio unit 42 to output a voice message as an alarm sound, it generates an audio signal corresponding to the voice message based on message data stored in the storage unit 20. The audio unit 42 outputs the voice message (alarm sound) based on the audio signal generated by the control unit 10. Furthermore, when the control unit 10 detects the outbreak of a fire, it controls the display unit 41 to blink.

[0050] Here, when the control unit 10 detects the occurrence of a fire, it refers to the correspondence relationship information in the storage unit 20 and searches for name information (here, "living room") corresponding to the code information "A1" of the own device. Then, the control unit 10 generates an audio signal including the name information "living room" and causes the audio unit 42 to issue an alert.

[0051] On the other hand, when the control unit 10 acquires information notifying that a fire has been detected in the facility 7 as detection information from any one of the four slave units 101 (interlocking source) via the first communication unit 21, the control unit 10 transmits the detection information of the interlocking source to the external terminal 5 via the second communication unit 22. Furthermore, the control unit 10 transmits the detection information of the interlocking source to the other slave units 101 via the first communication unit 21 in order to interlock an alarm. Furthermore, when the control unit 10 receives information notifying that a fire has been detected in the facility 7 as detection information from the slave unit 101, the control unit 10 starts outputting an alarm sound from the audio unit 42. Furthermore, the control unit 10 controls the display unit 41 to blink.

[0052] Here, when the control unit 10 acquires detection information from any of the four child devices 101, it extracts the code information (for example, "A2") included in the detection information. The control unit 10 refers to the correspondence relationship information in the storage unit 20 and searches for the name information (here, "Bedroom") that corresponds to the link source code information "A2". The control unit 10 then generates an audio signal including the name information "Bedroom" and causes the audio unit 42 to issue an alert.

[0053] The detection information does not have to include a detection result in addition to the location information, and the control unit 10 may determine that a fire has been detected by another detector 1 using the receipt of location information (code information) as a trigger. The detection information does not have to include an identifier. In short, the detection information is information that includes at least location information.

[0054] In addition, since the code information is different from an identifier (identification information) unique to the detector 1, the same code information may be assigned to two or more detectors 1. For example, if two detectors 1 are installed on a staircase, the code information of both of these detectors 1 will be "A3".

[0055] (2.2.2) Child unit (first detector) Next, a description will be given of the configuration of four child units 101 (detectors 1B to 1E) among the multiple detectors 1. In the following, the same components as those in the parent unit 102 (detector 1A) will be given the same reference numerals as those in the parent unit 102, and the description thereof will be omitted as appropriate.

[0056] Each slave unit 101 is configured to detect the occurrence of an event that is a target for disaster prevention (here, a fire) in the same manner as the master unit 102. Each slave unit 101 has a detection function for detecting the occurrence of a fire in the facility 7 and an alarm function for issuing an alert when the occurrence of a fire in the facility 7 is detected.

[0057] Like the parent unit 102, each child unit 101 includes a control unit 10, a memory unit 20 (holding unit H1), a first communication unit 21, a second communication unit 22, a battery 23, a detection unit 3, and an alarm unit 4 (see FIG. 1). In addition to the above, the child unit 101 further includes circuit modules such as an audio circuit and a lighting circuit.

[0058] However, the second communication unit 22 is not an essential component for the child device 101 and may be omitted. Alternatively, for example, if a detector 1 having the same configuration can be set to either the child device 101 or the parent device 102 in response to a switching operation on a switch or the like, the detector 1 set to the child device 101 may be unused even if it has the function of the second communication unit 22.

[0059] The installation locations L1 of the four child devices 101 are a bedroom (space E2), a staircase (space E3), a child's room (space E4), and a kitchen (space E5), respectively.

[0060] The storage unit 20 of each slave unit 101 corresponds to the holding unit H1 and is configured with a device selected from a ROM, a RAM, an EEPROM, etc. The storage unit 20 stores a unique identifier (identification information) assigned to itself (its own device). The storage unit 20 also stores warning message data related to a voice message to be output as a warning sound.

[0061] Unlike the storage unit 20 of the parent unit 102, the storage unit 20 of each child unit 101 stores only location information related to the installation location L1 where the child unit is installed, and does not store location information related to the installation locations L1 where other detectors 1 are installed. In other words, the location information stored in the storage unit H1 of the child unit 101 is information related only to the installation location L1 of the child unit.

[0062] The control unit 10 of each child device 101 has a detection output unit 11, a setting output unit 12, a switching unit 13, and a setting unit 14. In other words, the control unit 10 has a function as the detection output unit 11, a function as the setting output unit 12, a function as the switching unit 13, and a function as the setting unit 14. The setting output unit 12, the switching unit 13, and the setting unit 14 will be described in detail later in the section "(2.5) Setting location information."

[0063] When the detector 1B detects the occurrence of a fire (event), the detection output unit 11 outputs at least location information to an output destination so that the output destination can make a report according to the location information of the detector. The output destination here includes the parent unit 102. For example, when the detector 1B detects the occurrence of a fire, the detection output unit 11 of the detector 1B outputs detection information including the code information "A2" of the detector 1B to the parent unit 102 so that a voice message such as "There's a fire in the bedroom. There's a fire in the bedroom" is output from the parent unit 102. The detection output unit 11 also outputs detection information including the code information "A2" of the detector 1B to the other three child units 101 via the parent unit 102 so that a voice message such as "There's a fire in the bedroom. There's a fire in the bedroom" is output to the other three child units 101. In other words, when each child unit 101 detects a fire, the detection output unit 11 of that child unit transmits its own detection information to the parent unit 102 via the first communication unit 21 in order to act as the linkage source and link the alarm.

[0064] When the control unit 10 of each slave unit 101 detects the occurrence of a fire, the control unit 10 of the slave unit 101 starts outputting an alarm sound from the audio unit 42 of the slave unit 101. When the control unit 10 of each slave unit 101 detects the occurrence of a fire, the control unit 10 of the slave unit 101 controls the display unit 41 of the slave unit 101 to blink.

[0065] When the control unit 10 of each slave unit 101 detects the occurrence of a fire, the control unit 10 of the slave unit 101 refers to the correspondence relationship information in the storage unit 20 of the slave unit 101 and searches for name information corresponding to the code information of the slave unit 101. The control unit 10 then generates an audio signal including the name information and causes the audio unit 42 of the slave unit 101 to notify the occurrence of a fire.

[0066] On the other hand, when the control unit 10 of each slave unit 101 acquires detection information notifying that a fire has been detected in the facility 7 from the master unit 102 via the first communication unit 21, the control unit 10 starts outputting an alarm sound from the audio unit 42 of the slave unit 101. Furthermore, the control unit 10 controls the display unit 41 of the slave unit 101 to blink.

[0067] Here, when the control unit 10 of each child unit 101 acquires detection information from the parent unit 102, it extracts code information contained in the detection information. In this case, the code information is code information of any of the four detectors 1 other than the child unit. The control unit 10 refers to the correspondence relationship information in the memory unit 20 of the child unit, and searches for name information corresponding to the code information of the linkage source (source of fire). Then, the control unit 10 generates an audio signal including the name information, and causes the audio unit 42 of the child unit to notify the user.

[0068] (2.3) External terminal As described above, the external terminal 5 (control device) is, for example, a controller for a home energy management system (HEMS), and is capable of communicating with a plurality of devices provided in the facility 7. The plurality of devices may include, for example, air conditioners, water heaters, etc. In this embodiment, the external terminal 5 is further capable of communicating with a master unit 102 (detector 1A) provided in the facility 7. The external terminal 5 is also capable of communicating with a plurality of slave units 101 (detectors 1B to 1E) via the master unit 102.

[0069] As shown in FIG. 1, the external terminal 5 includes a control unit 50, a communication unit 53, a storage unit 54, a display unit 55, and the like.

[0070] The control unit 50 has, for example, a computer system having a processor and a memory. The processor executes a program stored in the memory, causing the computer system to function as the control unit 50. The program executed by the processor is pre-recorded in the memory of the computer system here, but may be provided by being recorded on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet.

[0071] The communication unit 53 includes a first (communication) interface 53A for communicating with the parent unit 102 and the like. The first interface 53A receives various information from the parent unit 102 and the like by wireless communication using radio waves in a second frequency band (for example, 920 MHz band). The communication unit 53 also has a second (communication) interface 53B for communicating with the information terminal 6 and the external server 8 via a network NT1 (see FIG. 3) such as the Internet. The second interface 53B may communicate with the information terminal 6 via another device such as the external server 8. The information terminal 6 is a smartphone or a tablet terminal owned by a user (for example, a resident) of the facility 7. In this embodiment, the information terminal 6 is assumed to be a smartphone. Dedicated application software that enables wireless communication with the external terminal 5 is installed in the information terminal 6.

[0072] The storage unit 54 is configured with a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), and the like.

[0073] The storage unit 54 stores the identifier (identification information) of each of the multiple detectors 1. The storage unit 54 stores each of the multiple detectors 1 in association with the installation location L1 (any of the spaces E1 to E5) where the corresponding detector 1 is installed. Specifically, the storage unit 54 stores, for example, the identifier of the detector 1A in association with location information (code information) related to the installation location L1 (space E1) of the detector 1A. Similarly, the storage unit 54 stores the identifiers of the detectors 1B to 1E in one-to-one association with location information (code information) related to the installation locations L1 (spaces E2 to E5) of the detectors 1B to 1E. In addition to this, the storage unit 54 stores the correspondence relationship information commonly stored in the storage unit 20 of each detector 1, and information related to the information terminal 6 (for example, a telephone number).

[0074] 1, the control unit 50 has an acquisition unit 51, a registration unit 52, etc. In other words, the control unit 50 has a function as the acquisition unit 51 and a function as the registration unit 52.

[0075] The acquisition unit 51 is configured to acquire detection information of the multiple detectors 1 from the parent unit 102. Specifically, when any of the detectors 1 detects a fire, the acquisition unit 51 acquires the detection information from the parent unit 102 via the first interface 53A. The control unit 50 may display location information (name information) related to the installation location L1 of the detector 1 that is the source of the fire on the display unit 55 based on the acquired detection information. If the external terminal 5 has map information (floor plan, etc.) of the facility 7, the installation location L1 of the detector 1 that is the source of the fire may be displayed together with the map information so that it can be seen. If the external server 8 is a server device managed by a security company or the like, the external terminal 5 may notify the external server 8 that a fire has occurred based on the acquired detection information. The external terminal 5 may notify the information terminal 6 that a fire has occurred based on the acquired detection information.

[0076] Furthermore, the acquisition unit 51 is configured to acquire location information from the information terminal 6. The acquisition unit 51 acquires the location information via the second interface 53B in response to an operation input to the information terminal 6. The registration unit 52 registers the location information received from the information terminal 6 and the identifier of the detector 1 in the storage unit 54 in association with each other.

[0077] Specifically, in response to a request received from application software running on the information terminal 6, the external terminal 5 outputs, to the information terminal 6, identifiers and the like of the detectors 1 currently being installed or to be installed in the future (if they are being installed, name information such as "living room" may be acceptable). The resident may be able to perform operational input related to the addition, modification, deletion, etc. of location information corresponding to each detector 1 while referring to a list of identifiers and the like of the detectors 1 presented on the display screen of the information terminal 6.

[0078] If the external terminal 5 has map information (such as a floor plan) of the facility 7, it may associate the identifier of the detector 1 with the map information and display it on the display screen of the information terminal 6. The resident may tap a mark resembling the detector 1 to perform an operation input related to new addition, change, deletion, etc. of the location information corresponding to the detector 1.

[0079] The registration unit 52 registers (adds new information, changes, or deletes) the location information and the identifier of the detector 1 in association with each other in the storage unit 54 in response to the above-mentioned operation input from the information terminal 6. The external terminal 5 outputs the registered information to the parent unit 102 via the first interface 53A so that the registered information is also reflected in the storage unit 20 of the parent unit 102.

[0080] Since the external terminal 5 has the acquisition unit 51 and the registration unit 52, the user can register the location information of the detector 1 in the external terminal 5 from the information terminal 6.

[0081] The external terminal 5 manages the correspondence information commonly stored in the storage unit 20 of each detector 1. The external terminal 5 may output the correspondence information in response to a request received from an application software running on the information terminal 6. The resident may perform operation input related to new addition, change, deletion, etc. of name information corresponding to each code information while referring to the correspondence information presented on the display screen of the information terminal 6. For example, when the code information "A1" and the name information "living room" are associated with each other in the correspondence information, the name information corresponding to the code information "A1" may be changed from "living room" to "kitchen". Alternatively, the correspondence between the code information "B1" and the name information "entrance" may be newly added to the correspondence information. The name information may be changed to "XX's room" (XX is the name of the resident's child, etc.) according to the resident's preference, or the language may be changed from Japanese to English.

[0082] The external terminal 5 outputs the changed correspondence information to the parent device 102 via the first interface 53A in order to have the changed correspondence information reflected in the storage unit 20 of the parent device 102. Furthermore, the parent device 102 outputs the changed correspondence information to all the child devices 101 via the first communication unit 21 in order to have the changed correspondence information reflected in the storage unit 20 of the child devices 101.

[0083] The above-mentioned information such as the identifier, the correspondence information, the map information, the code information, and the name information is not limited to being stored and managed only in the memory unit 54 of the external terminal 5. Some or all of this information may be stored in the memory unit of the external server 8, for example. The external server 8 may manage this information for each facility 7. An administrator who manages the external server 8 may specify the facility 7 and change the settings of the above-mentioned information such as the identifier, the correspondence information, the map information, the code information, and the name information for the external terminal 5 of the facility 7.

[0084] The display unit 55 is a thin display device such as a liquid crystal display or an organic EL (electroluminescence) display. The display unit 55 may display the information acquired by the acquisition unit 51.

[0085] The external terminal 5 may perform operations such as adding, changing, and deleting location information corresponding to each detector 1 and changing the correspondence information by inputting operations into an operation unit provided in the housing of the external terminal 5. If the display unit 55 is a touch panel type display device, it may also have the function of the operation unit.

[0086] (2.4) Operation The operation of the detector management system 200 when a fire is detected will be briefly described below.

[0087] [Example 1] First, the operation of the detector management system 200 when the master unit 102 (detector 1A) detects a fire will be described with reference to FIG.

[0088] The parent unit 102 detects a fire (step ST1). The parent unit 102 issues an alert according to its own location information. That is, the parent unit 102 refers to the correspondence information according to the code information "A1" which is its own location information, and outputs a voice message including the name information "living room", "There's a fire in the living room. There's a fire in the living room", in succession to a sweep sound (step ST2). As described above, the voice message output from the parent unit 102 at the source of the fire may simply be "There's a fire. There's a fire."

[0089] The parent unit 102 also transmits the detection information to the other four child units 101 from the first communication unit 21 that performs wireless communication using radio waves in a first frequency band (e.g., 420 MHz band) (step ST3). However, FIG. 4 illustrates only one of the four child units 101. Each child unit 101 that receives the detection information extracts the code information "A1" contained in the detection information, and determines the name information "living room" that corresponds to the code information "A1" while referring to the correspondence relationship information in its own memory unit 20. Then, in conjunction with the alert issued by the parent unit 102, each child unit 101 outputs a voice message "There's a fire in the living room. There's a fire in the living room" in succession to the sweep sound (step ST4).

[0090] Furthermore, the parent device 102 transmits the detection information to the external terminal 5 by the second communication unit 22 that performs wireless communication using radio waves in a second frequency band (e.g., 920 MHz band) (step ST5). Based on the received detection information, the external terminal 5 displays on the display unit 55 that a fire has broken out in the living room (space E1) of the facility 7, and also notifies the information terminal 6, the external server 8, etc. (step ST6).

[0091] According to this, the parent unit 102 causes the child unit 101, which is the output destination of the detection information, to make a report according to the location information of the parent unit 102. This makes it possible to further improve the recognition of the location of the fire. In other words, it is possible to increase the possibility that the user can quickly recognize the source of the fire from the content of the alarm issued by the detector 1.

[0092] [Example 2] Next, the operation of the detector management system 200 when any of the four child devices 101 (detectors 1B to 1E) detects a fire will be described with reference to Fig. 5. As an example, it is assumed that the detector 1E installed in the kitchen detects a fire.

[0093] Detector 1E, which is child unit 101, detects a fire (step ST11). Detector 1E issues an alert according to its own location information. That is, detector 1E refers to the correspondence information according to the code information "A5", which is its own location information, and outputs a voice message including the name information "kitchen", "There's a fire in the kitchen. There's a fire in the kitchen", in succession to the sweep sound (step ST12). As described above, the voice message output from detector 1E at the source of the fire may simply be "There's a fire. There's a fire."

[0094] The detector 1E also transmits the detection information to the parent unit 102 by the first communication unit 21 that performs wireless communication using radio waves in a first frequency band (e.g., 420 MHz band) (step ST13). The parent unit 102 that receives the detection information extracts the code information "A5" included in the detection information, and determines the name information "kitchen" that corresponds to the code information "A5" while referring to the correspondence relationship information in the memory unit 20 of the parent unit 102. In conjunction with the alarm of the detector 1E, the parent unit 102 outputs a voice message "There's a fire in the kitchen. There's a fire in the kitchen" in succession to the sweep sound (step ST14).

[0095] Furthermore, the master unit 102 transmits the detection information to the other three slave units 101 (detectors 1B to 1D) by the first communication unit 21 that performs wireless communication using radio waves in a first frequency band (e.g., 420 MHz band) (step ST15). Based on the received detection information, the three slave units 101 (detectors 1B to 1D) output a voice message "There's a fire in the kitchen. There's a fire in the kitchen" in succession to a sweep sound (step ST16). However, only one of the three slave units 101 is illustrated in FIG. 5.

[0096] Furthermore, the parent unit 102 transmits the detection information to the external terminal 5 by the second communication unit 22 that performs wireless communication using radio waves in a second frequency band (e.g., 920 MHz band) (step ST17). Based on the received detection information, the external terminal 5 displays on the display unit 55 that a fire has occurred in the kitchen (space E5) of the facility 7, and also notifies the information terminal 6, the external server 8, etc. (step ST18).

[0097] According to this, the slave unit 101 makes the master unit 102 and other slave units 101, which are the output destinations of the detection information, report the occurrence of the fire according to the location information of the slave unit. Therefore, it is possible to further improve the recognition of the location of the fire. In other words, it is possible to increase the possibility that the user can quickly recognize the source of the fire from the contents of the alarm issued by the detector 1. Furthermore, since the master unit 102 has both the first communication unit 21 and the second communication unit 22, it is possible to easily send information on the slave unit 101 side to the external terminal 5. In particular, when the slave unit 101 (first detector) and the external terminal 5 use different frequency bands for wireless communication, when the slave unit 101 detects the occurrence of a fire, it is possible to easily send the location information of the slave unit 101 to the external terminal 5.

[0098] In the present embodiment, the storage unit 20 (holding unit H1) of each slave unit 101 stores only its own location information, and does not store location information of other units. Therefore, when multiple detectors 1 are newly installed or one or multiple detectors 1 are added, the effort of storing location information of all detectors 1 in one slave unit 101 can be eliminated, and the workload of setting location information can be reduced. In other words, each detector 1 does not need to manage in advance where other detectors 1 are installed and which identifiers they have before a fire occurs, and only needs to make an alert according to the location information received at the time a fire actually occurs.

[0099] (2.5) Setting location information The setting output unit 12, the switching unit 13 and the setting unit 14 in the control unit 10 of each detector 1 will be described below together with the operations related to setting of location information.

[0100] First, the setting of location information for each detector 1 will be described.

[0101] The switching unit 13 is configured to switch to one of a plurality of operation modes including at least a detection mode for detecting the occurrence of a fire (event) and a setting mode for setting location information for the memory unit 20 (holding unit H1). The operation modes may include, for example, an operation test mode for inspection, in addition to the detection mode and setting mode. The switching unit 13 switches the operation mode from the detection mode to the setting mode in response to, for example, the simultaneous pressing of two push button type operation units (which may be dip switches or the like) exposed from the housing of each detector 1.

[0102] When the operation mode is switched to the detection mode in each detector 1, the control unit 10 monitors whether or not a fire has occurred. When a fire is detected, the detector 1 executes the operation described in the above section "(2.4) Operation."

[0103] On the other hand, when the operation mode is switched to the setting mode in each detector 1, the setting unit 14 accepts the setting of location information in the storage unit 20 (holding unit H1). In this case, the setting unit 14 accepts the setting of one piece of candidate information as location information from a predetermined number of pieces of candidate information representing the location to be installed, for example. Specifically, a plurality of pieces of candidate information such as a living room, a staircase, an entrance, a back door, a kitchen, a washroom, a toilet, a bedroom, and a child's room are stored in advance in the storage unit 20 of each detector 1. Each of the plurality of pieces of candidate information is stored in the storage unit 20 in one-to-one correspondence with a plurality of pieces of code information. In short, the plurality of pieces of name information in the above-mentioned "correspondence relationship information" commonly stored in the storage unit 20 of each detector 1 corresponds to the plurality of pieces of candidate information referred to here.

[0104] For example, each time the user presses one of the two operation units of each detector 1 once, the candidate information is output as a voice message in ascending order from the first candidate information (living room in the above example) to the ninth candidate information (children's room in the above example). Also, each time the user presses the other of the two operation units once, the candidate information is output as a voice message in descending order. In other words, the setting unit 14 causes the audio unit 42 to output the multiple name information in the above-mentioned "correspondence relationship information" in sequence as a voice message in response to the user's pressing operation on the operation unit.

[0105] When a voice message of the candidate information desired by the user is output, the user presses the two operation units simultaneously again to determine the candidate information as the location information of the detector 1, and further switches the operation mode from the setting mode to the detection mode. The control unit 10 stores code information corresponding to the candidate information (name information) in the storage unit 20 as the location information of the detector. The control unit 10 may store the name information as it is as the location information of the detector.

[0106] In this embodiment, each detector 1 includes a switching unit 13 and a setting unit 14, so that location information can be set for each detector 1 according to the user's request or the installation environment of the detector 1. In particular, the setting unit 14 accepts the setting of one piece of candidate information from a predetermined number of pieces of candidate information as location information, so that the user can select location information from the multiple pieces of candidate information. As a result, the workability of setting location information for each detector 1 can be improved.

[0107] Next, registration of location information of each detector 1 to the external terminal 5 will be described.

[0108] When the setting unit 14 of the own device accepts the setting of location information, the setting output unit 12 outputs the location information and identification information of the own device so that the location information of the own device and the identification information of the own device are registered in association with each other in the external terminal 5. Here, the output destination of the location information and identification information in each detector 1 differs depending on whether the own device is the child device 101 or the parent device 102.

[0109] When the master device 102 (second detector) receives the location information setting at its own setting unit 14, it outputs its own location information and identification information to the external terminal 5 via its own second communication unit 22.

[0110] When each child device 101 (first detector) accepts the setting of location information at its setting unit 14, it outputs its own location information and identification information to the parent device 102 via its own first communication unit 21. Then, the parent device 102 outputs the location information and identification information received from the child device 101 to the external terminal 5 via its own second communication unit 22. Furthermore, the parent device 102 registers the location information and identification information received from the child device 101 in its own memory unit 20.

[0111] On the other hand, when the external terminal 5 receives the location information and the identification information of the detector 1 from the parent unit 102 via the first interface 53A, the external terminal 5 associates these and registers them in the storage unit 54. The external terminal 5 may transmit the location information and the identification information of the detector 1 to the external server 8.

[0112] In short, when the user sets the location information of the child device 101, the child device 101 causes the external terminal 5, via the parent device 102, to register its own location information and its own identification information in association with each other.

[0113] In this embodiment, each detector 1 includes a setting output unit 12. Therefore, when a slave unit 101 (first detector) and an external terminal 5 use different frequency bands for wireless communication and the slave unit 101 accepts location information setting, the location information of the slave unit 101 can be easily sent to the external terminal 5. In other words, the workability of registering the location information of the detector 1 in the external terminal 5 can be improved. In addition, the external terminal 5 can be made to manage a plurality of detectors 1.

[0114] (3) Modifications The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the same function as the detector 1 according to the above embodiment may be embodied in a control method for the detector 1, a computer program, or a non-transitory recording medium on which a computer program is recorded, etc.

[0115] Modifications of the above embodiment are listed below. The modifications described below can be combined as appropriate and applied. Hereinafter, the above embodiment may be referred to as a "basic example."

[0116] The control unit 10 of the detector 1 and the control unit 50 of the external terminal 5 in the present disclosure include a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the functions of the control unit 10 of the detector 1 and the control unit 50 of the external terminal 5 in the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be provided by being recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of an LSI, or a logic device that allows reconfiguration of the connection relationship within the LSI or reconfiguration of the circuit partition within the LSI, can also be employed as a processor. The electronic circuits may be integrated into one chip, or may be distributed among multiple chips. The chips may be integrated into one device, or may be distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Thus, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0117] Furthermore, it is not essential for the detector 1 and the external terminal 5 that the multiple functions of each of them are integrated into one housing, and each of the components of the detector 1 and the external terminal 5 may be distributed across multiple housings. Furthermore, at least a part of the functions of the detector 1, for example, a part of the functions of the detector 1, may be realized by the cloud (cloud computing) or the like. Similarly, at least a part of the functions of the external terminal 5, for example, a part of the functions of the external terminal 5, may be realized by the cloud or the like. Conversely, as in the basic example, the multiple functions of the detector 1 may be integrated into one housing, and the multiple functions of the external terminal 5 may be integrated into one housing.

[0118] In the basic example, the storage unit 20 (storage unit H1) of each detector 1 stores the correspondence information. However, the correspondence information is not essential, and the storage unit 20 of each detector 1 does not have to store the correspondence information. Specifically, in the basic example, when a fire is detected, the location information of the detection information transmitted and received between the slave unit 101 and the master unit 102, and between the master unit 102 and the external terminal 5 includes code information. However, instead of transmitting and receiving the code information as the location information, the name information representing the name of the installation location L1 may be transmitted and received as the location information. Alternatively, the detection information may include, as the location information, an audio signal corresponding to an audio message such as "There is a fire in the living room. There is a fire in the living room" that is actually output from the audio unit 42 of the detector 1 to be linked. However, as in the basic example, the configuration in which the storage unit 20 of each detector 1 stores the correspondence information and the code information is transmitted and received as the location information can reduce the amount of information (data length) related to the location information. In particular, when the detector 1 is battery-powered, the power consumption of the battery 23 can be reduced by suppressing the data length.

[0119] Furthermore, some of the multiple detectors 1 may hold the correspondence relationship information, while the remaining detectors 1 may not hold the correspondence relationship information. In this case, when a detector 1 that does not hold the correspondence relationship information receives detection information including code information, the control unit 10 of the detector 1 may cause the audio unit 42 to output an audio message such as "There's a fire in another room. There's a fire in another room."

[0120] In the basic example, each detector 1 is a home alarm device that includes an alarm unit 4 and has a function of notifying the occurrence of a fire by outputting an alarm sound (alarm function). However, the alarm unit 4 is not an essential component for each detector 1. At least one of the multiple detectors 1 does not need to have the function of notifying the occurrence of a fire. At least one of the multiple detectors 1 may simply transmit detection information to another device upon detecting the occurrence of a fire.

[0121] In the basic example, the memory unit 20 (holding unit H1) of the parent device 102 holds not only its own location information but also the location information of other devices (child devices 101). However, the memory unit 20 of the parent device 102 may also hold only its own location information and not the location information of other devices (child devices 101). However, it is desirable for the parent device 102 to manage (store) at least the number of child devices 101 and the identifiers of each child device 101.

[0122] (4) Advantages As described above, the detector (1) according to the first aspect detects the occurrence of an event that is a target of disaster prevention. The detector (1) includes a storage unit (H1) that stores location information related to at least the installation location (L1) where the detector (1) is installed. According to the first aspect, the storage unit (H1) stores the location information. Therefore, for example, the detector (1) itself issues an alert based on the location information, or another device issues an alert based on the location information of the detector (1), thereby improving the recognition of the location of the occurrence of the event that is a target of disaster prevention.

[0123] The detector (1) according to the second aspect is preferably the same as the detector (1) according to the first aspect, but further includes a detection output unit (11). When the detection output unit (11) detects the occurrence of an event, it is preferable that the detection output unit (11) outputs at least location information to an output destination so that the output destination issues a notification according to the location information of the detector (1). According to the second aspect, the output destination issues a notification according to the location information of the detector (1), thereby further improving the recognition of the location of an event that is a target of disaster prevention.

[0124] Regarding the detector (1) according to the third aspect, in the first or second aspect, it is preferable that the location information held by the holding unit (H1) is information related only to the installation location (L1) of the detector (1). According to the third aspect, for example, the workload of setting location information in the detector (1) can be reduced compared to a case in which the holding unit (H1) holds location information related to the installation locations (L1) of other detectors (1) in addition to location information related to its own installation location (L1).

[0125] The detector (1) according to the fourth aspect, in any one of the first to third aspects, preferably further includes a notification unit (4) that issues a notification according to location information of the detector (1) when an event occurrence is detected. According to the fourth aspect, the notification unit (4) issues a notification according to its own location information, so that it is possible to further improve the recognition of the location of the occurrence of an event that is a target of disaster prevention.

[0126] The detector (1) according to the fifth aspect is preferably in any one of the first to fourth aspects, further including a switching unit (13) and a setting unit (14). The switching unit (13) switches to one of a plurality of operation modes including at least a detection mode for detecting the occurrence of an event and a setting mode for setting location information for the holding unit (H1). When switched to the setting mode, the setting unit (14) accepts setting of location information. According to the fifth aspect, location information can be set for the detector (1) according to a user's request or an installation environment of the detector (1).

[0127] The detector (1) according to the sixth aspect is preferably the same as the fifth aspect, further including a setting output unit (12). When the setting unit (14) accepts setting of location information, the setting output unit (12) outputs the location information and the identification information so that the external terminal (5) can register the location information and the identification information of the detector (1) in association with each other. According to the sixth aspect, the detector (1) can register its own location information in the external terminal (5). In other words, the external terminal (5) can manage the detector (1).

[0128] In the fifth or sixth aspect of the detector (1) according to the seventh aspect, when the setting unit (14) is switched to the setting mode, it is preferable that the setting unit (14) accepts, as location information, one piece of candidate information from a predetermined number of pieces of candidate information representing a location to be installed. According to the seventh aspect, since the location information can be selected from the plurality of pieces of candidate information, it is possible to improve the workability of setting the location information in the detector (1).

[0129] With respect to the detector (1) according to the eighth aspect, in any one of the first to seventh aspects, it is preferable that the holding unit (H1) further holds correspondence information. The correspondence information is information in which name information representing the names of a plurality of installation locations (L1) is associated with a plurality of pieces of code information identifying the plurality of installation locations (L1). The location information is any one of the plurality of pieces of code information. According to the eighth aspect, for example, the amount of information related to the location information can be reduced compared to when the location information is name information representing the names of the installation locations (L1).

It is preferable that the second detector (parent unit 102) outputs at least location information received from the first detector (child unit 101) by its own first communication unit (21) to the external terminal (5) from its second communication unit (22). According to the twelfth aspect, when the first detector (child unit 101) detects the occurrence of an event between the first detector (child unit 101) and the external terminal (5) using different frequency bands, it is possible to easily send location information of the first detector (child unit 101) to the external terminal (5).

[0134] With respect to the detection system (100) according to the thirteenth aspect, in any one of the tenth to twelfth aspects, it is preferable that the first detector (child unit 101) further includes a setting unit (14) and a setting output unit (12). The setting unit (14) accepts the setting of location information for the holding unit (H1). When the setting unit (14) accepts the setting of location information, the setting output unit (12) outputs the location information and the identification information so that the external terminal (5) associates the location information with the identification information of the detector (1) and registers them. It is preferable that the setting output unit (12) of the first detector (child unit 101) outputs the location information and the identification information to the second detector (parent unit 102) via its first communication unit (21). It is preferable that the second detector (parent unit 102) outputs the received location information and the identification information to the external terminal (5) via its second communication unit (22). According to the thirteenth aspect, when the first detector (child device 101) and the external terminal (5) use different frequency bands, when the first detector (child device 101) accepts the setting of location information, the location information of the first detector (child device 101) can be easily sent to the external terminal (5). In other words, the workability of registering the location information of the detector (1) in the external terminal (5) can be improved.
