[0003] [Patent Document 1] JP 2013-089076 A [Patent Document 2] JP 2017-117472 A [Patent Document 3] JP 2008-234533 A [Patent Document 4] JP 2018-106326 A [Patent Document 5] Patent Publication No. 2018-088105 Summary of the Invention [Problem to be solved by the invention]

[0004] In a fire alarm system, when the smoke density reaches a predetermined fire detection density, for example, a fire detector sends a fire signal to a receiver to start the accumulation operation, and when the predetermined accumulation conditions are met, it is determined that there is a fire.However, before it is determined that there is a fire, precursor phenomena to fire, such as a gradual increase in smoke density, as in a smoldering fire, are observed, and if these precursor phenomena to fire are recognized before it is determined that there is a fire, it becomes possible to deal with the situation quickly and appropriately whether it is a fire or not.

[0005] The present invention aims to provide a disaster prevention support system and a disaster prevention support method that detects precursory phenomena of a fire using a fire detector and enables prompt and appropriate response by linking the fire detector with a mobile device carried by a person involved in a fire prevention object. [Means for solving the problem]

[0006] (First invention) The present invention provides a disaster prevention support system, A fire detector connected via a signal line to a receiver of a fire alarm system installed in a fire prevention object and a mobile terminal carried by a person involved in the fire prevention object are connected via a short-range network whose communication area is at least the fire alarm system and its surrounding area, The fire detector transmits a fire signal to a receiver via a signal line when it determines that there is a fire, and transmits a support activation signal via a short-range network to the fire alarm equipment and a mobile terminal located in the vicinity of the fire detector when it determines that there is a fire precursor before determining that there is a fire. The mobile terminal acquires and stores disaster prevention support information from a support device connected via a wide area network in advance, and reads and displays predetermined disaster prevention support information when a support activation signal is received from a fire detector; The support device functions as a receiver when it receives a fire signal from a fire detector via a wide area network and a local area network during inspection of the receiver.

[0007] Here, a fire precursor is a precursor phenomenon that has a high possibility of leading to a fire, and also includes precursor phenomena caused by non-fire factors such as smoke or steam from cooking, smoke from smoking, etc., which do not have the possibility of leading to a fire.

[0008] (Second Invention) The present invention provides a disaster prevention support system, A fire detector connected via a signal line to a receiver of a fire alarm system installed in a fire prevention facility and a mobile terminal carried by a person involved in the fire prevention facility and connectable to a wide area network are connected via a short-range network whose communication area is at least the fire alarm system and its surrounding area, The receiver transmits the detection value received from the fire detector to the support device connected via the short-range network and the wide-area network; The support device transmits a support activation signal to the fire alarm equipment and the mobile terminals located in the vicinity thereof via the wide area network and the short distance network when it determines that a fire is present based on the detection value; The mobile terminal is characterized in that it reads out and displays predetermined disaster prevention support information when it receives a support activation signal from the support device.

[0009] (Third Invention) The present invention provides a disaster prevention support system, A fire detector connected via a signal line to a receiver of a fire alarm system installed in a fire prevention facility and a mobile terminal carried by a person involved in the fire prevention facility and connectable to a wide area network are connected via a short-range network whose communication area is at least the fire alarm system and its surrounding area, The fire detector transmits the detected value to a support device connected via a short-range network and a wide-area network; The support device transmits a support activation signal to the fire alarm equipment and the mobile terminals located in the vicinity thereof via the wide area network and the short distance network when it determines that a fire is present based on the detection value; The mobile terminal is characterized in that it reads out and displays predetermined disaster prevention support information when it receives a support activation signal from the support device. [Effects of the Invention]

[0010] (Effects of disaster prevention support systems) According to the disaster prevention support system of the present invention, when a fire detector determines that there is a fire precursor, a support activation signal can be sent via a short-range network to a mobile terminal carried by a person involved in the fire alarm equipment and the fire prevention object located in its vicinity, causing disaster prevention support information to be displayed.This allows the person involved in the fire alarm equipment or its vicinity to be aware of the fire precursor determined by the fire detector and to take appropriate measures, including checking the site, at the stage of the fire precursor phenomenon.

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

[0012] (Effect of displaying the relative positions of the fire point and the mobile device) In addition, the mobile devices of relevant personnel at or near the fire alarm equipment will display map information on their screen showing the relative position of the fire point determined to be a fire precursor and their own device (the relevant personnel's own mobile device), allowing them to accurately determine the location of the fire point and take appropriate action, such as checking the site.

[0013] (Effect of displaying the name of the area where fire signs are present and information on how to deal with them) In addition, the mobile devices of relevant personnel at or near the fire alarm system will display the area name of the fire detector that has been determined to be a fire warning sign and information on how to deal with the fire warning sign on their screen, allowing them to understand the location where the fire warning sign has been determined to be a fire warning sign and take appropriate action in accordance with the fire warning sign information.

[0014] (Effect of on-site confirmation and response transmission) In addition, relevant personnel at and around the fire alarm equipment will check the scene in accordance with the instructions in the fire warning response information and respond by transmitting a fire confirmation signal to the fire detector if there is a fire, or a non-fire confirmation signal if there is no fire.Based on this, the fire detector will transmit a fire confirmation signal or a non-fire confirmation signal to the receiver, and will be able to issue a fire alarm if a fire is confirmed, or a non-fire alarm if no fire is confirmed, at the stage when the fire detector determines that there is a fire warning.

[0015] (Effects 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 to the mobile terminal via a wide area network and stored in advance, so that the disaster prevention support information can be appropriately displayed when the fire detector determines that there is a sign of a fire.

[0016] (Effect of fire warning detection) In addition, when the smoke concentration or temperature detected by the fire detector is lower than a predetermined fire judgment value and a predetermined fire precursor judgment accumulation condition is met, it is judged to be a fire precursor, thereby making it possible to reliably capture precursor phenomena that have a high possibility of leading to a fire and judge them to be fire precursors.

[0017] (Effectiveness of fire detectors) The fire detector of the present invention can be connected to a receiver via a conventional signal line, and also to a mobile terminal carried by a person involved in the fire prevention object via a short-distance network, and can operate the fire alarm equipment by directly transmitting a predetermined signal to the mobile terminal of the person involved in the fire prevention object or in the vicinity thereof. Other features of the fire detector can provide the same effects as those of the disaster prevention support method described above. [Brief explanation of the drawings]

[Figure 5] Time chart showing the operation of the disaster prevention support system [Figure 6] FIG. 10 is an explanatory diagram showing a second embodiment of the disaster prevention support system according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0019] [First embodiment of disaster prevention support system] (Fire alarm equipment) As shown in Figure 1, fire alarm systems 10 (10-1, 10-2, 10-3, etc.) are installed in fire prevention facilities such as buildings, and as shown representatively in fire alarm system 10-1, fire detectors 16 are connected to signal lines 14 that are drawn from receivers 12, for example, on a floor-by-floor basis in 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 is connected via an antenna 18 to mobile phone terminals 20 (20-1, 20-2, etc.) such as smartphones held by persons involved in the fire prevention object via a wireless LAN network that functions as a short-range network.

[0021] Here, the communication distance of the WiFi (registered trademark) network is about 100 meters, and that of the Bluetooth (registered trademark) network is about 10 to 20 meters, and in order to cover the entire area of ​​the fire alarm equipment 10 (10-1, 10-2, 10-3, etc.) as a communication area, repeaters will be installed as necessary.

[0022] In addition, people related to fire prevention objects who carry mobile phone terminals 20 (20-1, 20-2, ...) include disaster prevention managers and disaster prevention personnel working in disaster prevention centers and manager's offices, security company personnel who patrol fire prevention objects, and disaster prevention personnel assigned to each floor by companies or other entities that occupy the building.

[0023] (Preliminary fire assessment and fire assessment) The fire alarm system 10 of this embodiment is an R-type (Record-type) fire alarm system. A unique address is assigned to each fire detector 16, and the receiver 12 transmits a batch A / D conversion command signal at a predetermined interval, for example, every second, to A / D convert the smoke density or temperature detection signals detected by the sensor units of all the fire detectors 16, store the detected smoke density or temperature values, and then transmits a call signal sequentially specifying the detector addresses, thereby polling each fire detector 16 to return a response signal including the detected smoke density or temperature value.

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

[0025] When the receiver 12 receives a fire interrupt signal from a fire detector 16, it transmits a group search command signal specifying the group address, performs a group search to identify the group address that responded with the fire interrupt signal, then transmits an intra-group search command signal specifying the detector addresses within the searched group address in sequence, identifies the address of the fire detector 16 that responded with the fire interrupt signal, i.e., the fire detector 16 that has determined a preliminary fire, and outputs a warning alert (pre-alarm) indicating a preliminary fire.

[0026] Next, when the smoke concentration detection value from the fire detector 16 that has determined a preliminary fire reaches a predetermined fire judgment value and satisfies a predetermined fire judgment accumulation condition, for example, when the smoke concentration detection value exceeds the fire judgment value a predetermined number of times in succession, the receiver 12 determines that a fire has occurred and outputs a fire alarm by sounding a main sound or a local sound, and also performs fire alarm operations including linkage control of predetermined smoke prevention and exhaust equipment, etc., and outputting a report to an external device.

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

[0028] The mobile phone terminals 20 (20-1, 20-2, etc.) are connected to a support server 30 that 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 request signal for sending disaster prevention support information including the equipment identifier of the fire alarm equipment 10 (10-1, 10-2, 10-3, etc.) from the mobile phone terminal 20 (20-1, 20-2, etc.), it transmits the disaster prevention support information corresponding to the fire alarm equipment 10 (10-1, 10-2, 10-3, etc.) corresponding to the equipment identifier and stores it in advance in the mobile phone terminal 20 (20-1, 20-2, etc.).

[0030] The disaster prevention support information stored in advance in the mobile phone terminal 20 (20-1, 20-2, ...) includes at least map information (floor map, etc.) of buildings, etc. that are fire prevention targets, the address of the fire detector 16 and the district name indicating the installation location, and fire sign response information indicating the response action to be taken if a fire sign is determined to be present.

[0031] The fire sign response information also includes operational instructions for the relevant person to check the installation site of the fire detector 16 that has been determined to be a fire sign, and to respond by transmitting the result of the check as to whether there is a fire or not.

[0032] The mobile phone terminals 20 (20-1, 20-2, ...) that have received the support activation signal from the fire detector 16 display map information on their screens showing the fire and their own locations (mobile phone terminals 20-1, 20-2) based on the fire location information included in the support activation signal and map information (floor map, etc.) of the building, etc. included in the pre-stored disaster prevention support information. This allows relevant parties to understand the fire location relative to the current locations of the mobile phone terminals 20 (20-1, 20-2, ...) from the map information displayed on the screen, and can then go to the fire location and check the site based on the on-site confirmation response instructions displayed on the screen at the same time.

[0033] On-site confirmation of the location of the fire based on the judgment of fire signs is done by a person, so if there is a fire, it can be confirmed without a doubt. Also, since the fire is in the early stages, it can be extinguished early using a fire extinguisher, etc. On the other hand, if there is a non-fire factor such as smoke or steam from smoking or cooking, it can be confirmed that there is no fire.

[0034] The person who has checked the scene sends a fire confirmation signal or a non-fire confirmation signal to the fire detector 16 that has been determined to be a fire precursor by touching the screen of the 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, and performs predetermined fire alarm operations, interlocking control, signal transfer control, etc. based on the fire confirmation.

[0036] On the other hand, when 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 the user that there is no fire, and restores the receiver 12 based on the restoration operation of the person in charge.

[0037] [Configuration and functions of receivers and fire detectors] As shown in Figure 2, the receiver 12 is provided with a receiver control unit 32 that uses a computer circuit equipped with a CPU, memory, and various input / output ports, and the receiver control unit 32 is connected to a transmission unit 34, a display 36, a display unit 38, an operation unit 40, an acoustic alarm unit 42, and a reporting unit 44.

[0038] The fire detector 16 is provided with a detector control unit 45 using a computer circuit equipped 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 determines that a preliminary fire has occurred, 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 determines that a preliminary fire has occurred and that a fire is imminent, it transmits a support activation signal from the antenna 18 via the wireless communication unit 50 to the mobile phone terminals 20 (20-1, 20-2, ...) shown in FIG.

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

[0042] [Mobile phone terminal] (Mobile phone terminal configuration) 3, the mobile phone terminal 20 is exemplified by a smartphone, which is known as a mobile phone terminal that also has the functions of a personal portable computer. The mobile phone control unit 52 of the mobile phone terminal 20 is realized by an LSI equipped with a CPU, memory, and various input / output interfaces, and executes installed programs to perform various controls for communication connections such as call connections, email connections, and Internet connections, as well as disaster prevention support controls 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 a support activation signal from the fire detector 16.

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

[0044] The wireless LAN communication unit 56 performs wireless communication in accordance with IEEE802.11 based on a wireless LAN network such as Wi-Fi (registered trademark) or Bluetooth (registered trademark), and also functions as a wireless LAN access point.

[0045] The GPS communication unit 58 acquires the longitude and latitude of the current location using the Global Positioning System, which uses orbiting satellites. The camera unit 60 captures images using a CMOS image sensor, and acquires still images and videos.

[0046] The SIM card 62 is a card that stores an IMSI (International Mobile Subscriber Identity) number, which is a number for identifying a mobile phone number, and by replacing the SIM card 62, the same mobile phone number can be used on multiple mobile phone terminals.

[0047] The display 64 uses a display device such as a liquid crystal panel or an organic EL panel, and has a touch panel 66 on the panel surface. The audio input / output unit 68 is equipped with a microphone, a speaker, and an audio codec and performs audio input and output.

[0048] The operation unit 70 accepts user operations via the keypad and operation buttons to perform telephone control, etc. The memory card 72 is a removable external memory, and is used for externally storing various data such as images captured by the camera unit 60.

[0049] (Disaster prevention support screen) 4, the mobile phone terminal 20 displays a disaster prevention support screen 74 when it receives a support activation signal from the fire detector 16. The disaster prevention support screen 74 displays a fire sign warning message 76 saying "There is a sign of a fire," followed by fire sign occurrence information 78, including the time of occurrence and the name of the area where the occurrence occurred (location of the fire spot).

[0050] Next, an on-site check is instructed as a response instruction 80 for the fire signs, and then map information 82 is displayed. The map information 82 displays the fire point 84 and the user's own aircraft 86, and by knowing the relative positions of the two, the relevant person can go from the current position of the user's aircraft 86 to the fire point 84 and check the on-site to see if 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, and 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, and 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 to send a fire confirmation signal, the locations of fire extinguishing equipment such as fire extinguishers and fire hydrants may be displayed on the map information 82 to assist in initial fire extinguishing.

[0052] [Disaster prevention support system operation] 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 equipment 10 where the mobile phone terminal 20 is located.In step S2, the support server 30 transmits the disaster prevention support information of the fire alarm equipment 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 polling (calling) by sequentially specifying a batch AD conversion command and the detector address at a one-minute cycle, and in response, in step S5, the fire detector 16 AD converts the smoke concentration or temperature detection signal, stores it as a detection value, and responds with the detection value in response to the polling.

[0054] If the fire detector 16 determines a preliminary fire in step S6, it transmits a fire interrupt signal to the receiver 12 in step S7. The receiver 12 searches for the address of the fire detector 16 that issued the fire interrupt in step S8 and outputs a caution alarm.

[0055] When the fire detector 16 determines in step S10 that a predetermined fire sign accumulation condition is satisfied and thus that a fire sign 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 to instruct the user to check the site, and in step S13 sends a fire confirmation signal or a non-fire confirmation signal to the fire detector 16 that has determined that there is a fire precursor based on the fire or non-fire confirmation response operation.

[0057] In step S14, when the fire detector 16 receives a fire confirmation signal, it transmits a fire confirmation signal to the receiver 12, and 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 receives a fire confirmation signal and confirms that there is a fire, and issues a fire alarm. In response to a non-fire confirmation signal, the receiver stops the warning alarm associated with the preliminary fire determination and issues a non-fire alert, and then recovers based on the recovery operation.

[0059] [Second embodiment of disaster prevention support system] As shown in FIG. 6, the second embodiment of the disaster prevention support system is characterized in that tablet terminals 100 (100-1, 100-2, . . . ) are provided as mobile terminals.

[0060] The tablet terminals 100 (100-1, 100-2, etc.) carried by persons involved in the fire prevention object are equipped with wireless LAN communication functions such as WiFi (registered trademark) or Bluetooth (registered trademark), and are connected to the fire detectors 16 via a wireless LAN network that functions as a short-range network, enabling the tablet terminals 100 (100-1, 100-2, etc.) to transmit an assistance activation signal when the fire detectors 16 determine that there is a sign of a fire, and the tablet terminals 100 (100-1, 100-2, etc.) to transmit a fire confirmation signal or a non-fire confirmation signal based on on-site confirmation to the fire detectors 16.

[0061] Furthermore, the tablet terminals 100 (100-1, 100-2, etc.) connect to the support server 30 via the wireless LAN adapter 102, the wireless LAN base station (access point) 28, and the Internet 26, and acquire disaster prevention support information from the support server 30 and store it in advance.

[0062] This allows the tablet terminals 100 (100-1, 100-2, etc.) to perform the same control operations as the mobile phone terminals 20 (20-1, 20-2, etc.) shown in the first embodiment.

[0063] [Modifications of the present invention] (Fire warning signs determination) As another form of determining whether a fire is a precursor to fire, the fire detector 16 may determine the rate of change of the smoke concentration detection value or the 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 a predetermined fire precursor determination accumulation condition, for example, when the preliminary fire change rate is exceeded a predetermined number of times in succession, it may determine that a fire is a precursor to fire, and send a support activation signal to the mobile phone terminal 20 or the tablet terminal 100.

[0064] (Acquisition of disaster prevention support information) The disaster prevention support information may be stored in the mobile phone terminal 20 by the support server 30 acquiring longitude and latitude location information in advance using the GPS function of the mobile phone terminal 20, identifying the fire alarm system 10 and the mobile phone terminals 20 located in its vicinity, and transmitting the disaster prevention support information to the identified mobile phone terminals 20 for storage.

[0065] (Duplication of fire alarm systems) In addition to being connected to a conventional receiver via a signal line, fire detectors can also be connected to a support server on the Internet via a mobile device such as a cell phone or tablet, or directly. This means that, for example, the fire alarm system can be duplicated by providing the support server with fire receiver functionality.

[0066] If the fire alarm system is duplicated, for example, when the receiver is inspected, fires can be monitored using the system system of the support server and fire detectors. In addition, the duplication of the fire alarm system allows for the creation of new functions and usage patterns.

[0067] (Transmitter function of mobile device) In addition, in the disaster prevention support system of the present invention, the detection value of, for example, smoke density from the fire detector 16 received by the receiver 12 is transmitted to the support server 30, and when the support server 30 determines that there is a fire sign (for example, a smoke density of 3% / m) or a preliminary fire sign that is a precursor to a fire sign (for example, a smoke density 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 in the vicinity thereof, and the mobile phone terminal 20 (20-1, 20-2) displays a transmitter image on its screen and outputs a predetermined warning sound as necessary.

[0068] When the transmitter screen is displayed, the relevant person carrying the mobile phone terminal 20 (20-1, 20-2) will know that a fire precursor phenomenon is occurring and will check the site, or if they have already noticed a fire precursor phenomenon that could be the cause of a fire precursor or a preliminary fire precursor, they can touch the push button of the transmitter image displayed on the screen of the mobile phone terminal 20-1, 20-2, and a fire notification signal will be sent to the receiver 12 via the support server 30, and the receiver 12 will determine that a fire has been confirmed and issue a fire alarm.

[0069] Therefore, at the stage of a fire precursor phenomenon that is determined to be a fire precursor or a preliminary fire precursor, a virtual transmitter exists in the mobile phone terminal 20 (20-1, 20-2), and it becomes possible to report a fire using the virtual transmitter on the mobile phone terminal 20 (20-1, 20-2) without having to go out and search for a place where an actual fire transmitter is installed.

[0070] (Transmitter function of mobile device) In addition, in the disaster prevention support system of the present invention, the detection value of, for example, smoke density detected by the fire detector 16 is transmitted to the support server 30 via the mobile phone terminal 20 (20-1, 20-2), and when the support server 30 determines that there is a fire sign (for example, a smoke density of 3% / m) or a preliminary fire sign that is a precursor to a fire sign (for example, a smoke density 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 the vicinity thereof, and the mobile phone terminal 20 (20-1, 20-2) displays a transmitter image on the screen and outputs a predetermined warning sound as necessary.

[0071] When the transmitter screen is displayed, the relevant person carrying the mobile phone terminal 20 (20-1, 20-2) will know that a fire precursor phenomenon is occurring and will check the site, or if they have already noticed a fire precursor phenomenon that could be the cause of a fire precursor or a preliminary fire precursor, they can touch the push button of the transmitter image displayed on the screen of the mobile phone terminal 20-1, 20-2, which will send a fire notification signal to the receiver 12 via the support server 30, and the receiver 12 will determine that a fire has been confirmed and issue a fire alarm.

[0072] In addition, the receiver 12 that receives the fire alarm signal transmits a fire alarm response signal to the mobile phone terminal 20 (20-1, 20-2) via the support server 30, and the response lamp of the transmitter image displayed on the screen lights up to indicate that the signal has been received by the receiver 12.

[0073] Therefore, at the stage of a fire precursor phenomenon that is determined to be a fire precursor or a preliminary fire precursor, a virtual transmitter exists in the mobile phone terminal 20 (20-1, 20-2), and it becomes possible to report a fire using the virtual transmitter on the mobile phone terminal 20 (20-1, 20-2) without having to go out and search for a place where an actual fire transmitter is installed.
