Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in fire alarm equipment, when a fire detector receives a fire signal when, for example, the smoke density reaches a predetermined fire determination density, an accumulation operation is started, and when a predetermined accumulation condition is satisfied, it is determined as a fire. However, before determining as a fire, for example, a precursor phenomenon of a fire such as a slow increase in smoke density in a smoldering fire is observed. If this precursor phenomenon of the fire is known before determining as a fire, it becomes possible to quickly and appropriately handle the case of a fire and the case of non-fire.

[0005] The present invention aims to provide a disaster prevention support system and method that enables rapid and appropriate response by detecting precursory fire phenomena with fire detectors and coordinating fire detectors with portable terminals carried by persons responsible for the building. [Means for solving the problem]

[0006] (First Invention) The present invention is a disaster prevention support system, A fire detector connected via a signal line to the receiver of a fire alarm system installed in a building subject to fire protection regulations, and a portable terminal carried by a person in charge of the building subject to fire protection regulations, are connected via a short-range network whose communication area is at least the fire alarm system and its surroundings. When a fire is detected, the fire detector transmits a fire signal to the receiver via a signal line, and when it detects a fire precursor before a fire is detected, it transmits an auxiliary activation signal via a short-range network to the fire alarm system and mobile terminals located in its vicinity. The mobile terminal acquires and stores disaster prevention support information in advance from support devices connected via a wide-area network, and when it receives a support activation signal from a fire detector, it reads and displays predetermined disaster prevention support information. The support device is characterized by its function as a receiver when it receives a fire signal from a fire detector via a wide-area network and a short-range network during receiver inspection.

[0007] Here, fire warning signs refer to phenomena that indicate a high probability of leading to a fire, and also include warning signs caused by non-fire factors such as smoke and steam from cooking, and smoke from smoking, which do not have the potential to cause a fire.

[0008] (Second invention) The present invention is a disaster prevention support system, A fire detector connected via a signal line to the receiver of a fire alarm system installed in a building subject to fire protection, and a portable terminal carried by a person in charge of the building subject to fire protection and capable of connecting to a wide-area network, are connected via a short-range network whose communication area is at least the fire alarm system and its surroundings. The receiver transmits the detection values ​​received from the fire detector to support devices connected via the short-range network and wide-area network. When the support device determines, based on the detected values, that there is a fire precursor, it transmits a support activation signal via a wide-area network and a short-range network to the fire alarm system and mobile terminals located in its vicinity. The mobile terminal is characterized by reading and displaying predetermined disaster prevention support information when it receives a support activation signal from a support device.

[0009] (Third invention) The present invention is a disaster prevention support system, A fire detector connected via a signal line to the receiver of a fire alarm system installed in a building subject to fire protection, and a portable terminal carried by a person in charge of the building subject to fire protection and capable of connecting to a wide-area network, are connected via a short-range network whose communication area is at least the fire alarm system and its surroundings. The fire detector transmits the detected values ​​to support devices connected via short-range and wide-area networks. When the support device determines, based on the detected values, that there is a fire precursor, it transmits a support activation signal via a wide-area network and a short-range network to the fire alarm system and mobile terminals located in its vicinity. The mobile terminal is characterized by reading and displaying predetermined disaster prevention support information when it receives a support activation signal from a support device. [Effects of the Invention]

[0010] (Effectiveness of disaster prevention support systems) According to the disaster prevention support system of the present invention, when a fire detector detects a fire precursor, a support activation signal can be transmitted via a short-range network to a mobile terminal carried by persons in the vicinity of the fire alarm system and the building in question, which will then display disaster prevention support information. Personnel in the vicinity of the fire alarm system can then be aware of the fire precursor detected by the fire detector and take appropriate action, including on-site verification, at the stage of the precursory phenomena of a fire.

[0011] In addition, the support activation signal from the fire detector is received by the fire alarm equipment where the fire detector that has determined a fire omen is installed or by the mobile terminal of the relevant person in the vicinity thereof, and the support information is displayed, enabling prompt action including on-site confirmation.

[0012] (Effect by displaying the positional relationship between the fire point and the mobile terminal) In addition, on the mobile terminal of the relevant person in the fire alarm equipment or in its vicinity, the positional relationship between the fire point determined as a fire omen and the device itself (the mobile terminal of the relevant person) is displayed on the screen as map information, enabling accurate grasping of the position of the fire point and taking response actions such as on-site confirmation.

[0013] (Effect by displaying the district name of the fire omen and the response information) In addition, on the mobile terminal of the relevant person in the fire alarm equipment or in its vicinity, the district name of the fire detector determined as a fire omen and the fire omen response information are displayed on the screen, enabling grasping of the location where the fire omen is determined and appropriately taking response actions according to the fire omen response information.

[0014] (Effect of on-site confirmation and response transmission) In addition, the relevant persons in the fire alarm equipment and its vicinity confirm the site according to the instructions of the fire omen response information, and if it is a fire, they transmit a fire confirmation signal, and if it is not a fire, they transmit a non-fire confirmation signal to the fire detector. Based on this, the fire detector transmits a fire confirmation signal or a non-fire confirmation signal to the receiver, and can perform the notification of a fire alarm due to fire confirmation or the notification of non-fire due to non-fire confirmation at the stage when the fire detector determines a fire omen.

[0015] (Effect of obtaining disaster prevention support information) In addition, disaster prevention support information specific to the fire alarm equipment is obtained from a support device connected via a mobile terminal and a wide area network and stored in advance, and the disaster prevention support information can be appropriately displayed when the fire detector determines a fire omen.

[0016] (Effect of fire omen determination) In addition, when the detection value of the smoke density or temperature by the fire detector is lower than a predetermined fire determination value and a predetermined fire omen determination accumulation condition is satisfied, it is determined as a fire omen, so that a precursor phenomenon highly likely to lead to a fire can be surely captured and determined as a fire omen.

[0017] (Effect of the fire detector) In addition to being connected to a receiver via a conventional signal line, the fire detector of the present invention can be connected to a mobile terminal carried by a person related to a fire prevention target via a short-range network, and a predetermined signal required by the fire notification equipment or the mobile terminal of a person in the vicinity thereof can be directly transmitted from the fire detector to operate it. Regarding other features of the fire detector, the same effects as those of the above-described disaster prevention support method can be obtained.

Modes for Carrying Out the Invention

[0019] [First Embodiment of the Disaster Prevention Support System] (Fire Notification Equipment) As shown in FIG. 1, fire notification equipment 10 (10-1, 10-2, 10-3 ···) is installed in a fire prevention target such as a building. As represented by fire notification equipment 10-1, a fire detector 16 is connected to a signal line 14 drawn out from a receiver 12, for example, in units of floors of the building.

[0020] The fire detector 16 is connected to the receiver 12 via a signal line 14 and is equipped with a wireless LAN communication unit such as WiFi (registered trademark) or Bluetooth (registered trademark), and connects via an antenna 18 to mobile phone terminals 20 (20-1, 20-2...) such as smartphones owned by persons in charge of the building, via a wireless LAN network that functions as a short-range network.

[0021] Here, the WiFi® network has a communication range of approximately 100 meters, and the Bluetooth® network has a range of approximately 10 to 20 meters. In order to cover the entire area of ​​the fire alarm system 10 (10-1, 10-2, 10-3, etc.) as a communication area, repeaters will be installed as needed.

[0022] Furthermore, persons involved with fire-protected buildings who carry mobile phone terminals 20 (20-1, 20-2, ...) include disaster prevention managers and personnel working in disaster prevention centers and management offices, security company personnel who patrol fire-protected buildings, and disaster prevention personnel designated on each floor by companies occupying the building.

[0023] (Preliminary fire assessment and fire assessment) The fire alarm system 10 in this embodiment is an R-type (Record-type) fire alarm system. Each fire detector 16 is assigned a unique address, and the receiver 12 transmits a batch A / D conversion command signal at a predetermined interval, for example, every 1 second, to perform A / D conversion on the smoke concentration or temperature detection signals detected by, for example, the sensor unit of all fire detectors 16 and store the smoke concentration detection value or temperature detection value. Subsequently, the receiver 12 performs polling by transmitting call signals that sequentially specify the detector addresses, causing each fire detector 16 to return a response signal including the smoke concentration detection value or temperature detection value.

[0024] The fire detector 16 determines a preliminary fire when the smoke density detection value reaches a predetermined preliminary fire determination value, for example, 3% / m, which is lower than a predetermined fire determination value, for example, 10% / m, for the receiver 12 to determine a fire, and transmits a fire interrupt signal to the receiver 12. The fire interrupt signal is, for example, an all-1-bit signal that disables all signals transmitted and received via the signal line 14.

[0025] Upon receiving a fire interrupt signal from the fire detector 16, the receiver 12 sends a group search command signal specifying a group address, performs a group search to identify the group address that responded with the fire interrupt signal, and then sends group search command signals sequentially specifying the detector addresses within the found group address, identifies the address of the fire detector 16 that responded with the fire interrupt signal, i.e., the fire detector 16 that was determined to be a preliminary fire, and outputs a warning alarm (pre-alarm) indicating a preliminary fire.

[0026] Next, when the smoke concentration detected by the fire detector 16, which has been determined to be a preliminary fire, reaches a predetermined fire determination value and satisfies predetermined fire determination accumulation conditions, for example, when the smoke concentration detected by the fire detection value exceeds the fire determination value for a predetermined number of consecutive times, the receiver 12 determines that there is a fire and outputs a fire alarm by sounding the main sound or area sound, and performs fire alarm operations including interlocking control of predetermined smoke control equipment and outputting a transmission alarm to an external device.

[0027] (Fire warning sign assessment and disaster prevention support) When the smoke concentration detection value exceeds a preliminary fire detection value of 3% / m, which is lower than the fire detection value of 10% / m, and a predetermined fire precursor judgment accumulation condition is met, for example, when the smoke concentration detection value exceeds the preliminary fire detection value for a predetermined number of consecutive times, the fire detector 16 determines that a fire is imminent and transmits a support activation signal from the antenna 18 to the mobile phone terminal 20 (20-1, 20-2...) via the wireless LAN network. This support activation signal includes the address of the fire detector 16 that has been determined to be imminent.

[0028] The mobile phone terminals 20 (20-1, 20-2, etc.) connect to a support server 30, which functions as a support device, via a mobile phone base station 24, a mobile phone network 22, and the internet 26.

[0029] When the support server 30 receives a transmission request signal for disaster prevention support information, including the equipment identifier of a fire alarm system 10 (10-1, 10-2, 10-3...), from a mobile phone terminal 20 (20-1, 20-2, ...), it transmits disaster prevention support information corresponding to the fire alarm system 10 (10-1, 10-2, 10-3...) corresponding to the equipment identifier, and stores it in advance on the mobile phone terminal 20 (20-1, 20-2, ...).

[0030] The disaster prevention support information pre-stored in the mobile phone terminal 20 (20-1, 20-2, ...) includes at least map information (floor maps, etc.) of buildings that are subject to fire prevention regulations, district names indicating the addresses and installation locations of fire detectors 16, and fire warning response information indicating the actions to take if a fire warning is detected.

[0031] Furthermore, the fire warning response information includes operational instructions for the relevant parties to check the installation site of the fire detector 16 that they have determined to be a fire warning, and to transmit a response indicating whether there is a fire or not based on the results of the check.

[0032] Upon receiving a support activation signal from the fire detector 16, the mobile phone terminals 20 (20-1, 20-2, ...) display map information on their screens, indicating the location of the fire and their own location (mobile phone terminals 20-1, 20-2), based on the fire location information included in the support activation signal and map information of buildings, etc. (floor maps, etc.) included in the disaster prevention support information stored in advance. This allows relevant personnel to understand the location of the fire relative to the current location of the mobile phone terminals 20 (20-1, 20-2, ...) from the map information displayed on the screen, and simultaneously, based on the on-site confirmation instructions displayed on the screen, they can go to the fire location and conduct an on-site confirmation.

[0033] On-site confirmation of the fire source location based on fire precursor assessment is done by humans, so if there is a fire, it can be confirmed with certainty. Furthermore, if the fire is in its initial stages, it can be extinguished with fire extinguishers, etc. On the other hand, if the cause is a non-fire factor such as cigarette smoke or steam from cooking, it can be confirmed that there is no fire.

[0034] Personnel who have conducted on-site inspections transmit a fire confirmation signal or a non-fire confirmation signal to the fire detector 16 that has determined it to be a fire precursor by touching the screen of a mobile phone terminal 20 (20-1, 20-2, ...).

[0035] When the fire detector 16 receives a fire confirmation signal, it transmits a fire confirmation signal to the receiver 12 via the signal line 14, causing the receiver to perform predetermined fire alarm actions, interlocking control, and alarm transfer control based on the confirmed fire.

[0036] On the other hand, if the fire detector 16 receives a non-fire confirmation signal, the receiver 12 transmits a non-fire confirmation signal via the signal line 14, stops the warning alarm associated with the preliminary fire determination, notifies that the fire has been confirmed, and restores the receiver 12 based on the recovery operation performed by the person in charge.

[0037] [Configuration and Function of Receivers and Fire Detectors] As shown in Figure 2, the receiver 12 is equipped with a receiver control unit 32 which uses a computer circuit with a CPU, memory, and various input / output ports. The receiver control unit 32 is connected to a transmission unit 34, a display 36, a display unit 38, an operation unit 40, an audible alarm unit 42, and a transmission unit 44.

[0038] The fire detector 16 is equipped with a detector control unit 45 that uses a computer circuit with a CPU, memory, and various input / output ports, and is connected to a sensor unit 46 that detects smoke concentration or temperature, a transmission unit 48 that functions as a wired communication unit, and a wireless communication unit 50 that performs wireless LAN communication such as WiFi (registered trademark) or Bluetooth (registered trademark).

[0039] When the detector control unit 45 detects a preliminary fire, it instructs the transmission unit 48 to transmit a fire interrupt signal to the receiver 12 via the signal line 14. Furthermore, when the detector control unit 45 detects a fire precursor while it has detected a preliminary fire, it transmits an assist activation signal from the antenna 18 via the wireless communication unit 50 to the mobile phone terminals 20 (20-1, 20-2, ...) shown in Figure 1.

[0040] Furthermore, when the sensor control unit 45 receives a fire confirmation signal from the mobile phone terminal 20 (20-1, 20-2, etc.) shown in Figure 1, it instructs the transmission unit 48 to transmit a fire confirmation signal to the receiver 12 via the signal line 14.

[0041] Furthermore, when the sensor control unit 45 receives a non-fire confirmation signal from the mobile phone terminal 20 (20-1, 20-2...) shown in Figure 1, it instructs the transmission unit 48 to transmit a confirmed non-fire signal to the receiver 12 via the signal line 14.

[0042] [Mobile phone] (Mobile phone terminal configuration) As shown in Figure 3, the mobile phone terminal 20 is a smartphone, which is known as a mobile phone terminal that also functions as a personal portable computer. The mobile phone control unit 52 of the mobile phone terminal 20 is implemented with an LSI equipped with a CPU, memory, and various input / output interfaces, and executes installed programs and performs various control functions related to communication connections such as call connections, email connections, and internet connections, as well as disaster prevention support control such as sending support information request signals to the support server 30, receiving and storing disaster prevention support information from the support server 30, and reading and displaying disaster prevention support information based on support activation signals from the fire detector 16.

[0043] The mobile phone communication unit 54 performs mobile phone communication using the W-CDMA standard, also known as the third-generation mobile communication system (3G), or the IMT-Advanced standard, also known as the fourth-generation mobile communication system (4G).

[0044] The wireless LAN communication unit 56 performs wireless communication compliant with IEEE 802.11 based on a wireless LAN network using Wi-Fi (registered trademark) or Bluetooth (registered trademark). The wireless LAN communication unit 56 also functions as a wireless LAN access point.

[0045] The GPS communication unit 58 uses the Global Positioning System (GSO) with orbiting satellites to obtain the longitude and latitude of the current location. The camera unit 60 uses a CMOS image sensor to capture images and obtain still images and videos.

[0046] The SIM card 62 is a card that stores the IMSI (International Mobile Subscriber Identity) number, which is used to identify a mobile phone number. By swapping the SIM card 62, the same mobile phone number can be used on multiple mobile phone devices.

[0047] The display 64 uses a display device such as an LCD panel or an OLED panel, and a touch panel 66 is placed on the surface of the panel. The audio input / output unit 68 is equipped with a microphone, speaker, and audio codec to perform audio input and output.

[0048] The control unit 70 accepts user input via a keypad and control buttons and performs telephone control, etc. The memory card 72 is a removable external memory and is used for external storage of various data such as images captured by the camera unit 60.

[0049] (Disaster prevention support screen) As shown in Figure 4, when the mobile phone terminal 20 receives a support activation signal from the fire detector 16, it displays the disaster prevention support screen 74. The disaster prevention support screen 74 displays the fire warning message 76, which reads "This is a fire warning," followed by fire warning occurrence information 78, which includes the time of occurrence and the district name of the location (fire point).

[0050] Next, as instruction 80 for dealing with fire signs, an on-site inspection is ordered, followed by the display of map information 82. Map information 82 displays the fire point 84 and the user's own device 86, and by understanding the relative positions of the two, the relevant personnel can proceed from the current position of their own device 86 to the fire point 84 to confirm whether there is a fire or not.

[0051] Next, a response instruction 88, a fire confirmation button 90, and a non-fire confirmation button 92 are provided. When a fire is confirmed, touching the fire confirmation button 90 sends a fire confirmation signal to the fire detector 16 that has determined it to be a fire precursor. When a non-fire is confirmed, touching the non-fire confirmation button 92 sends a non-fire confirmation signal to the fire detector 16 that has determined it to be a fire precursor. When the fire confirmation button 90 is touched and a fire confirmation signal is sent, the locations of fire extinguishing equipment such as fire extinguishers and fire hydrants may be displayed on the map information 82 to support initial fire suppression.

[0052] [Operation of the disaster prevention support system] As shown in Figure 5, in step S1, the mobile phone terminal 20 requests the transmission of disaster prevention support information specifying the equipment identifier of the fire alarm system 10 where it is located. In step S2, the support server 30 transmits the disaster prevention support information for the fire alarm system 10 specified by the equipment identifier to the mobile phone terminal 20, and stores it in step S3.

[0053] In step S4, the receiver 12 performs a polling (call) by sequentially specifying a batch AD conversion command with a 1-minute cycle and the detector address. In response, in step S5, the fire detector 16 performs an AD conversion of the smoke concentration or temperature detection signal, stores it as a detection value, and responds to the polling with the detection value.

[0054] When the fire detector 16 detects a preliminary fire in step S6, it sends a fire interrupt signal to the receiver 12 in step S7. In step S8, the receiver 12 searches for the address of the fire detector 16 that issued the fire interrupt and outputs a warning alarm.

[0055] If the fire detector 16 determines in step S10 that a predetermined fire precursor accumulation condition has been met and that a fire precursor has occurred, it transmits a support activation signal to the mobile phone terminal 20 in step S11.

[0056] Upon receiving the support activation signal, the mobile phone terminal 20 displays disaster prevention support information on the disaster prevention support screen 74 shown in Figure 4 in step S12 and instructs on-site confirmation. In step S13, based on the confirmation response operation for fire or non-fire, it transmits a fire confirmation signal or a non-fire confirmation signal to the fire detector 16 that has determined it to be a fire precursor.

[0057] When the fire detector 16 receives a fire confirmation signal in step S14, it transmits a fire confirmation signal to the receiver 12. When it receives a non-fire confirmation signal, it transmits a non-fire confirmation signal to the receiver 12.

[0058] In step S15, the receiver 12 confirms the presence of a fire as a receiving operation in response to the fire confirmation signal and activates a fire alarm. In response to the non-fire confirmation signal, it stops the caution alarm associated with the preliminary fire determination, notifies that there is no fire, and restores the system based on the restoration operation.

[0059] [Second embodiment of the disaster prevention support system] As shown in Figure 6, the second embodiment of the disaster prevention support system is characterized by the provision of tablet terminals 100 (100-1, 100-2...) as portable terminals.

[0060] The tablet terminals 100 (100-1, 100-2...) carried by persons in charge of the fire-protected building are equipped with wireless LAN communication functions such as WiFi (registered trademark) or Bluetooth (registered trademark), and connect to the fire detector 16 via a wireless LAN network that functions as a short-range network. This enables the transmission of support activation signals to the tablet terminals 100 (100-1, 100-2...) when the fire detector 16 determines that there is a fire precursor, and the transmission of fire confirmation signals or non-fire confirmation signals to the fire detector 16 based on on-site confirmation from the tablet terminals 100 (100-1, 100-2...).

[0061] Furthermore, the tablet terminal 100 (100-1, 100-2, etc.) connects to the support server 30 via a wireless LAN adapter 102, a wireless LAN base station (access point) 28, and the internet 26, and obtains disaster prevention support information from the support server 30 and stores it in advance.

[0062] As a result, the tablet terminal 100 (100-1, 100-2...) can perform the same control operations as the mobile phone terminal 20 (20-1, 20-2...) shown in the first embodiment.

[0063] [Modified version of the present invention] (Determining signs of a fire) Another method for determining a fire precursor using the fire detector 16 is to determine the rate of change of the smoke concentration detection value or temperature detection value, and when this rate of change reaches a predetermined preliminary fire change rate that is lower than the fire determination change rate and satisfies the predetermined fire precursor determination accumulation conditions, for example, when the preliminary fire change rate is exceeded a predetermined number of consecutive times, a fire precursor may be determined and a support activation signal may be transmitted to the mobile phone terminal 20 or tablet terminal 100.

[0064] (Acquisition of disaster prevention support information) For disaster prevention support information to be stored on the mobile phone terminal 20, the support server 30 may first use the GPS function of the mobile phone terminal 20 to obtain location information of longitude and latitude, identify the mobile phone terminal 20 located in and around the fire alarm system 10, and then transmit the disaster prevention support information to the identified mobile phone terminal 20 for storage.

[0065] (Duplication of fire alarm systems) Furthermore, in addition to signal line connections with conventional receivers, fire detectors can connect to support servers on the internet via mobile devices such as mobile phones and tablet devices, or directly. For example, by providing the functionality of a fire alarm receiver on the support server, the fire alarm system can be made redundant.

[0066] When fire alarm systems are duplicated, for example, when a receiver is being inspected, fire monitoring can be performed using the support server and fire detector systems. In addition to this, duplicating fire alarm systems can create new functions and usage patterns.

[0067] (Transmitter function of mobile device) Furthermore, in the disaster prevention support system of the present invention, the receiver 12 transmits, for example, the smoke concentration detection value from the fire detector 16 to the support server 30. When the support server 30 determines that there is a fire precursor (for example, a smoke concentration of 3% / m) or a preliminary fire precursor (for example, a smoke concentration of 1.5% / m), it transmits a transmitter support signal to the fire alarm equipment 10-1 or a mobile phone terminal 20 (20-1, 20-2) located nearby. The mobile phone terminal 20 (20-1, 20-2) displays a transmitter image on its screen and outputs a predetermined warning sound as needed.

[0068] Persons carrying a mobile phone terminal 20 (20-1, 20-2) can, upon seeing the transmitter screen displayed, become aware that a precursor to a fire is occurring and proceed to investigate the scene. Alternatively, if they have already noticed a precursor to a fire or a preliminary fire, they can touch the button on the transmitter image displayed on the mobile phone terminal 20-1, 20-2. A fire alert signal is then transmitted to the receiver 12 via the support server 30, and the receiver 12 determines that a fire has been confirmed and issues a fire alarm.

[0069] Therefore, at the stage of fire precursor phenomena that are judged to be fire signs or preliminary fire signs, a virtual transmitter exists on the mobile phone terminal 20 (20-1, 20-2), making it possible to report a fire using the virtual transmitter on the mobile phone terminal 20 (20-1, 20-2) without having to search for and go to the location where an actual fire alarm transmitter is installed.

[0070] (Transmitter function of mobile device) Furthermore, in the disaster prevention support system of the present invention, the detection value of smoke concentration detected by the fire detector 16 is transmitted to the support server 30 via the mobile phone terminal 20 (20-1, 20-2). When the support server 30 determines that this is a fire precursor (e.g., smoke concentration of 3% / m) or a preliminary fire precursor (e.g., smoke concentration of 1.5% / m), it transmits a transmitter support signal to the fire alarm equipment 10-1 or the mobile phone terminal 20 (20-1, 20-2) located in its vicinity. The mobile phone terminal 20 (20-1, 20-2) then displays a transmitter image on its screen and outputs a predetermined warning sound as needed.

[0071] Persons carrying a mobile phone terminal 20 (20-1, 20-2) can, upon seeing the transmitter screen, become aware that a precursor to a fire is occurring and proceed to investigate the scene. Alternatively, if they have already noticed a precursor to a fire or a preliminary fire, they can touch the button on the transmitter image displayed on the mobile phone terminal 20-1, 20-2 screen, transmit a fire alarm signal to the receiver 12 via the support server 30, and the receiver 12, upon determining that a fire has been confirmed, issues a fire alarm.

[0072] Furthermore, the receiver 12, upon receiving the fire alarm signal, transmits a fire alarm response signal to the mobile phone terminals 20 (20-1, 20-2) via the support server 30, and the response lamp on the transmitter image displayed on the screen lights up to indicate that the receiver 12 has received the signal.

[0073] Therefore, at the stage of fire precursor phenomena that are judged to be fire signs or preliminary fire signs, a virtual transmitter exists on the mobile phone terminal 20 (20-1, 20-2), making it possible to report a fire using the virtual transmitter on the mobile phone terminal 20 (20-1, 20-2) without having to search for and go to the location where an actual fire alarm transmitter is installed.
