[0003] [Patent Document 1] JP 2013-089076 A [Patent Document 2] JP 2017-117472 A 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 method that detects precursory phenomena of a fire and enables prompt and appropriate response through cooperation between fire alarm equipment, support devices, and mobile terminals. [Means for solving the problem]

[0006] (Disaster prevention support method) The present invention provides a disaster prevention support method for a disaster prevention support system in which a fire alarm system having a receiver and a fire detector installed in a fire prevention object, a support device, and a mobile terminal carried by a person involved in the fire prevention object are connected via a network, First, the support device collects location information of the mobile device that has been detected in advance by the mobile device; Second, the receiver transmits the detection value received from the fire detector to the support device; Third, when the support device determines that there is a fire sign or a preliminary fire sign that is a precursor to a fire sign based on the detection value received from the receiver, the support device transmits a transmitter support signal to mobile terminals located inside the fire prevention object in which the fire alarm equipment is installed and in the vicinity of the fire prevention object; Fourthly, when the mobile terminal receives a transmitter support signal from the support device, it displays a transmitter image that serves as a virtual fire transmitter.

[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] (Caution sound output) The mobile terminal outputs a predetermined warning sound when displaying the transmitter image.

[0009] (Fire alarm output) The mobile terminal transmits a fire notification signal to the support device when the push button of the transmitter image displayed on the screen is touched, When the support device receives a fire alert signal from the mobile terminal, the support device transmits the fire alert signal to the receiver; The receiver outputs a fire alarm when it receives a fire notification signal from the support device.

[0010] (Send response) When the receiver receives the fire alert signal from the support device, the receiver transmits a fire alert response signal to the support device; When the support device receives the fire report response signal from the receiver, the support device transmits the fire report response signal to the mobile terminal; When the mobile terminal receives a fire report response signal from the support device, the mobile terminal turns on a response lamp of the transmitter image. [Effects of the Invention]

[0011] (Effects of disaster prevention support methods) According to the disaster prevention support method of the present invention, a support device such as a server detects the locations of mobile terminals carried by persons involved in the disaster prevention object, identifies the fire alarm system and the mobile terminals of persons involved in its vicinity, and transmits disaster prevention support information to them and stores it in advance.For example, when the receiver determines that there is a sign of a fire, it can detect the fire alarm system or a mobile terminal located in its vicinity, transmit a support activation signal, and display disaster prevention support information.This allows persons involved in the fire alarm system or its vicinity to become aware of the signs of a fire and take human action, including checking the site, at the stage of a precursor phenomenon that is likely to lead to a fire.

[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 who are near 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 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 or near the fire alarm equipment can follow the instructions in the fire warning response information displayed on their mobile device to check the scene and respond by transmitting a fire confirmation signal if there is a fire, or a non-fire confirmation signal if there is no fire.The receiver can then issue a fire alarm if it confirms there is a fire, or a non-fire if it confirms there is no fire, once it has determined that there is a fire warning.

[0015] (Effect of fire warning detection) In addition, when the smoke concentration or temperature detected by the fire detector is lower than the predetermined fire judgment value and the predetermined fire precursor judgment accumulation condition is met, or when a fire signal is received from a fire detector that has judged a fire and the predetermined fire judgment accumulation operation is started, a fire precursor is judged, thereby making it possible to reliably capture precursor phenomena before a fire is judged to be a fire and judge them to be fire precursors.

[Figure 4] Time chart showing the operation of the disaster prevention support system DETAILED DESCRIPTION OF THE INVENTION

[0017] [Configuration and Functions of Disaster Prevention Support System] (Fire alarm equipment) As shown in Figure 1, fire alarm systems 10 (10-1, 10-2, 10-3) 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 drawn from receivers 12, for example, on a floor-by-floor basis in the building.

[0018] The fire alarm system 10 of this embodiment is an R-type (Record-type) fire alarm system as an example. A unique address is set 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, performs A / D conversion on the smoke density or temperature detection signals detected by the sensor units of all fire detectors 16, stores the detected smoke density or temperature values, and then transmits a call signal sequentially specifying the detector addresses, thereby performing polling to have each fire detector 16 return a response signal including the detected smoke density or temperature value.

[0019] (Fire warning signs determination) 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.

[0020] 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, and then transmits an intra-group search command signal specifying the detector addresses within the searched group address in sequence, to identify the addresses of the fire detectors 16 that responded with the fire interrupt signal, i.e., the fire detectors 16 that have determined a preliminary fire.

[0021] Next, when the smoke density detection value from the fire detector 16 that has been determined to be a preliminary fire satisfies a predetermined fire sign determination accumulation condition, for example, when the smoke density detection value exceeds the preliminary fire determination value a predetermined number of times in succession, the receiver 12 determines that it is a fire sign, transmits a fire sign determination signal as a communication signal to the support server 30, and also outputs a warning warning (pre-alarm) indicating a preliminary fire.

[0022] 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.

[0023] In addition, the determination of fire signs may not be made by the receiver 12, but when the smoke concentration detection value of the fire detector 16 reaches a predetermined preliminary fire determination value and a predetermined fire sign determination accumulation condition is met, for example, when the smoke concentration detection value exceeds the preliminary fire determination value a predetermined number of times in succession, a fire sign may be determined to have occurred and a fire sign determination signal may be sent to the receiver 10.

[0024] (Support server) A wireless LAN adapter 18 is connected to the receiver 12, and when it determines that there is a fire sign, a fire sign determination signal is transferred and output to the wireless LAN adapter 18, and is then transmitted to a support server 30 functioning as a support device via a wireless LAN base station 26 and the Internet 28. The fire sign determination signal includes predetermined terminal information such as the address of the fire detector 16 that has been determined to be a fire sign, and the name of the district where it is installed.

[0025] The support server 30 is connected to a mobile phone terminal 20 such as a smartphone via the Internet 28, a mobile phone network 22, and a mobile phone base station 24.

[0026] The support server 30 pre-registers, for each fire prevention object in which a fire alarm system 10 (10-1, 10-2, 10-3) is installed, the mobile terminal identification information of the mobile telephone terminals 20 (20-1, 20-2, ...) carried by persons involved in the fire prevention object.

[0027] Those involved in registering the mobile terminal identification information of mobile terminal 20 (20-1, 20-2, ...) include disaster prevention managers and disaster prevention staff working in the disaster prevention center or manager's office, security company staff patrolling fire prevention targets, and disaster prevention staff designated for each floor of a company or other entity that occupies a building.

[0028] The support server 30 periodically transmits a location information request signal specifying the registered mobile terminal identification information, and collects location information of the mobile phone terminals 20 (20-1, 20-2, . . .). The mobile phone terminals 20 are equipped with a GPS function, and upon receiving a location information request signal from the support server 30, the mobile phone terminals 20 operate the GPS function to detect the latitude and longitude indicating their current location as location information, and transmit this to the support server 30.

[0029] When the support server 30 receives location information from the mobile phone terminal 20 (20-1, 20-2, ...), it compares it with the location information of a predetermined equipment installation area including the fire alarm equipment 10 (10-1, 10-2, 10-3) and its vicinity, determines the mobile phone terminal 20 (20-1, 20-2, ...) whose detected position is included in the equipment installation area, for example, the fire alarm equipment 10-1 and the mobile phone terminals 20-1 and 20-2 located in its vicinity, and transmits and pre-stores predetermined disaster prevention support information.

[0030] The disaster prevention support information includes at least map information (floor map, etc.) of the building, etc. that is the fire prevention target, the address of the fire detector 16 and the name of the district indicating the installation location, and fire sign response information indicating the response action to be taken when a fire sign is determined. The fire sign response information also includes instructions to check the installation site of the fire detector 16 that has been determined to be a fire sign, and to respond and transmit whether there is a fire or not.

[0031] (Support by receiving fire warning signals) When the support server 20 receives a fire warning determination signal from the receiver 12, it acquires location information from pre-registered mobile phone terminals 20 (20-1, 20-2, ...), and at that time, it determines, for example, mobile phone terminal 20-1 located in the fire alarm equipment 10-1 and, for example, mobile phone terminal 20-2 located in the vicinity thereof, and transmits a support activation signal, and the mobile phone terminals 20-1 and 20-2 read out disaster prevention support information stored in advance and display it on the screen.

[0032] The support activation signal transmitted from the support server 30 to the mobile phone terminals 20-1 and 20-2 includes location information of the fire point indicating the location of the fire detector 16 that has been determined to be a fire precursor, and the mobile phone terminals 20-1 and 20-2 display map information on their screens indicating the location of the fire point and their own device (mobile phone terminals 20-1 and 20-2) based on the location information of the fire point included in the support activation signal and map information (floor map) of the building, etc. included in the disaster prevention support information stored in advance.

[0033] This allows the relevant person carrying the mobile phone terminal 20-1, 20-2 to understand the location of the fire point relative to their current location from the map information displayed on the screen, and at the same time, based on the on-site confirmation response instructions displayed on the screen, go to the fire point location and confirm whether there is a fire or not.

[0034] On-site confirmation of the location of the fire based on the assessment 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 its 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.

[0035] The relevant parties who have checked the scene send a fire confirmation signal or a non-fire confirmation signal to the support server 30 by touching the screen of the mobile phone terminal 20-1, 20-2, and the support server 30 then sends the signal to the receiver 12 of the fire alarm system 10-1.

[0036] When the receiver 12 receives a fire confirmation signal, this corresponds to receiving a fire notification signal by operating the push button on the transmitter, so it determines that a fire has been confirmed and performs the specified fire alarm operation, interlocking control, and signal transfer control, etc.

[0037] On the other hand, when the receiver 12 receives a no-fire confirmation signal, it stops the warning alarm associated with the preliminary fire determination, notifies the user that there is no fire, and restores the system based on the restoration operation of the person in charge.

[0038] [Mobile phone terminal] (Mobile phone terminal configuration) 2, the mobile phone terminal 20 is exemplified by a smartphone that also has the functions of a personal portable computer. The mobile phone control unit 32 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 various related controls. It also performs disaster prevention support control such as detecting location information based on a location information request signal from the support server 30 and transmitting a response signal, receiving and storing disaster prevention support information transmitted from the support server 30, and reading and displaying disaster prevention support information based on a support activation signal transmitted from the support server 30.

[0039] The mobile phone communication unit 34 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).

[0040] The wireless LAN communication unit 36 ​​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.

[0041] The GPS communication unit 38 uses the Global Positioning System, which uses orbiting satellites, to communicate to obtain the longitude and latitude of the current location. The camera unit 40 uses a CMOS image sensor to capture images and obtain still images and videos.

[0042] The SIM card 42 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 42, the same mobile phone number can be used on multiple mobile phone terminals.

[0043] The display 44 uses a display device such as a liquid crystal panel or an organic EL panel, and has a touch panel 46 on the panel surface. The audio input / output unit 48 includes a microphone, a speaker, and an audio codec, and performs audio input and output.

[0044] The operation unit 50 accepts user operations via the keypad and operation buttons to perform telephone control, etc. The memory card 52 is a removable external memory, and is used for externally storing various data such as images captured by the camera unit 40.

[0045] (Disaster prevention support screen) 3, the mobile phone terminal 20 displays a disaster prevention support screen 54 when it receives a support activation signal from the support server 30. The disaster prevention support screen 54 displays a fire sign warning message 56 saying "There is a sign of a fire," followed by the time of the fire sign occurrence information 58 and the name of the area where the fire occurred (location of the fire).

[0046] Next, an on-site check is instructed as a response instruction 60 for the fire signs, and then map information 62 is displayed. The map information 62 displays the fire point 64 and the user's own aircraft 66, and the relative positions of the two are clear, and the relevant person goes to the fire point 64 from the current position of the user's aircraft 66 to check the on-site whether there is a fire or not.

[0047] Next, a response instruction 68, a fire confirmation button 70, and a non-fire confirmation button 72 are provided, and when a fire is confirmed, touching the fire confirmation button 70 sends a fire confirmation signal to the support server 30, and when a non-fire is confirmed, touching the non-fire confirmation button 72 sends a non-fire confirmation signal to the support server 30. When the fire confirmation button 70 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 support initial fire extinguishing.

[0048] [Disaster prevention support system operation] As shown in FIG. 4, the support server 30 transmits a location information request signal, for example, periodically, in step S1, and the mobile phone terminal 20 acquires latitude and longitude location information using the GPS function and transmits it to the support server 30 in step S2.

[0049] In step S3, the support server 30 determines whether the location information obtained from the mobile phone terminal 20 is located in or around the fire alarm equipment, and if it is located, in step S4 it sends disaster prevention support information to the mobile phone terminal 20 and stores it in step S5.

[0050] If the receiver 12 determines in step S6 that there is a fire sign, it transmits a fire sign determination signal to the support server 30 in step S7 and also outputs a warning warning indicating a preliminary fire. Upon receiving the fire sign determination signal, the support server 30 transmits a location information request signal to the mobile phone terminal 20 in step S8, and the mobile phone terminal 20 operates its GPS function and transmits the detected location information to the support server 30 in step S9.

[0051] When the support server 30 determines that the location of the mobile phone terminal 20 acquired in step S10 is a fire alarm system or its vicinity, it sends a support activation signal to the mobile phone terminal 20 in step S11, displays a disaster prevention support screen as shown in Figure 3 in steps S12 and S13, and sends a fire confirmation signal or a non-fire confirmation signal to the support server 30 in step S14 based on the fire or non-fire confirmation response operation.

[0052] In step S15, the support server 30 transmits a fire confirmation signal or a non-fire confirmation signal to the receiver 12, and in step S16, when the receiver 12 receives a fire confirmation signal, it confirms that there is a fire and performs a fire alarm operation, and when it receives a non-fire confirmation signal, it stops the caution alarm, reports that there is no fire, and recovers based on the recovery operation.

[0053] [Modifications of the present invention] (Fire warning signs determination) As another form of determining whether a fire is present, the receiver 12 may determine whether a failure is present when the smoke concentration detection value or temperature detection value from the fire detector 16 that is the subject of the fire detection reaches a predetermined fire determination value and initiates a predetermined accumulation operation.

[0054] As another method for determining whether a fire is present, the rate of change of the smoke concentration detection value or temperature detection value of the fire detector 16 is calculated, and when this rate of change reaches a predetermined preliminary fire determination rate that is lower than the fire determination rate of change and satisfies a predetermined fire precursor determination accumulation condition, for example, when the rate of change exceeds the preliminary fire determination rate a predetermined number of times in succession, a fire precursor can be determined.

[0055] (Fire alarm equipment) Although the above embodiment has been described using an R-type (Record-type) fire alarm system as an example, a P-type (Proprietary-type) fire alarm system may also be used. A P-type fire alarm system monitors fires for each line connected to an on-off type fire detector, and the receiver determines that a fire is present when it starts fire detection and accumulation based on a line alert.

[0056] (Mobile device) In the above embodiment, the mobile phone terminal 20 is used as the mobile terminal, but it may also be a mobile terminal device such as a tablet terminal.

[0057] (network) Furthermore, the network between the receiver 12, the mobile phone terminal 20, and the support server 30 is not limited to the Internet 28 and the mobile phone network 22, but may include any appropriate network configuration.

[0058] (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.

[0059] 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.

[0060] In addition, the receiver 12 that has received the fire notification signal transmits a fire notification response signal to the mobile phone terminal 20 (20-1, 20-2) via the support server 30, and the receiver 12 changes the image of the transmitter displayed on the screen. The response lamp lights up to indicate that the receiver 12 has received the signal.

[0061] 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.

[0062] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited to the numerical values ​​shown in the above embodiments. [Explanation of symbols]
