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 from a fire detector when, for example, the smoke concentration reaches a predetermined fire determination concentration, it starts an accumulation operation, and when a predetermined accumulation condition is satisfied, it determines that there is a fire. However, before determining that there is a fire, for example, a precursor phenomenon of a fire such as a slow increase in smoke concentration in a smoldering fire is observed. If this precursor phenomenon of the fire is detected before determining that there is a fire, it becomes possible to quickly and appropriately take measures in the case of a fire and the case of no fire.

[0005] An object of the present invention is to provide a disaster prevention support method that captures a precursor phenomenon of a fire and enables quick and appropriate measures by cooperation of a fire alarm device, a support device, and a mobile terminal.

Means for Solving the Problems

[0006] (Disaster prevention support method) The present invention relates to a disaster prevention support system and method, comprising a fire alarm system having a receiver and fire detector installed in a fire-protected building, a support device, and a portable terminal carried by persons in the fire-protected building, all connected via a network. Firstly, the support device collects location information of the mobile terminal that has been previously detected by the mobile terminal. Secondly, the receiver transmits the detection values ​​received from the fire detector to the support device. Thirdly, when the support device determines a fire precursor or a preliminary fire precursor based on the detected values ​​received from the receiver, it transmits a transmitter support signal to portable terminals located inside the building where the fire alarm system is installed and in the vicinity of the building. Fourth, the mobile terminal is characterized by displaying a transmitter image that acts as a virtual fire alarm when it receives a transmitter support signal from the support device.

[0007] Here, fire warning signs refer to precursory phenomena that indicate a high probability of a fire occurring, and also include precursory phenomena 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] (Warning sound output) The mobile device emits a predetermined warning sound when displaying the transmitter image.

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

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

[0011] (Effectiveness of disaster relief methods) According to the disaster prevention support method of the present invention, a support device such as a server detects the location of a mobile terminal carried by persons involved with the object to be protected from disaster, identifies the mobile terminals of persons in the vicinity of the fire alarm system, transmits disaster prevention support information to them, and stores it in advance. For example, when a receiver determines that there is a fire precursor, it can detect the mobile terminal located in the vicinity of the fire alarm system, transmit a support activation signal, and display the disaster prevention support information. Persons in the vicinity of the fire alarm system can then be aware of the fire precursor and take human action, including on-site verification, at the stage of the precursory phenomena that have a high probability of leading to a fire.

[0012] (Effect of displaying the relative positions of the fire source and the mobile device) Furthermore, the fire alarm system or the mobile devices of personnel in its vicinity display the relative positions of the identified fire source and their own devices as map information, allowing them to accurately determine the location of the fire source and take appropriate action such as on-site verification.

[0013] (Effects of displaying the district name and response information for fire warning signs) Furthermore, the mobile devices of personnel in or near the fire alarm system will display the district name of the fire detector that was identified as a fire precursor, along with fire precursor response information. This allows them to identify the location of the fire precursor and take appropriate action according to the fire precursor response information.

[0014] (Effects of on-site verification and response transmission) In addition, the personnel in the vicinity of the fire alarm equipment should check the site in accordance with the instructions of the fire omen response information displayed on the mobile terminal. If it is a fire, they should transmit a fire confirmation signal; if it is not a fire, they should transmit a non-fire confirmation signal. The fire alarm can be notified by the receiver when a fire is confirmed, or the non-fire can be notified by non-fire confirmation at the stage when a fire omen is determined.

[0015] (Effect of Fire Omen Judgment) In addition, when the detection value of the smoke concentration or temperature by the fire detector is lower than the predetermined fire judgment value and the predetermined fire omen judgment accumulation condition is satisfied, or when a fire signal is received from the fire detector determined to be a fire and the predetermined fire judgment accumulation operation is started, by determining it as a fire omen, it is possible to surely capture the precursor phenomenon before determining it as a fire and determine it as a fire omen.

Embodiments for Carrying Out the Invention

[0017] [Configuration and Function of Disaster Prevention Support System] (Fire Alarm Equipment) As shown in FIG. 1, fire alarm equipment 10 (10-1, 10-2, 10-3) is installed in fire protection objects such as buildings. As represented by fire alarm equipment 10-1, a fire detector 16 is connected to a signal line 14 drawn from a receiver 12, for example, by floor units of a building.

[0018] 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. The receiver 12 performs A / D conversion of the smoke concentration or temperature detection signals detected by the sensor parts of all fire detectors 16 and stores the smoke concentration detection value or temperature detection value. Subsequently, it 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.

[0019] (Determining signs of a fire) 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.

[0020] 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 a fire interrupt signal, and then sends an in-group search command signal sequentially specifying the detector addresses within the searched group address, thereby identifying the address of the fire detector 16 that responded with a fire interrupt signal, i.e., the fire detector 16 that was determined to be a preliminary fire.

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

[0022] 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.

[0023] Alternatively, instead of the receiver 12 determining whether a fire has occurred, the fire detector 16 may determine that a fire has occurred when the smoke concentration detected reaches a predetermined preliminary fire determination value and the predetermined fire warning determination accumulation conditions are met, for example, when the smoke concentration detected exceeds the preliminary fire determination value for a predetermined number of consecutive times, and transmit a fire warning determination signal to the receiver 10.

[0024] (Support server) A wireless LAN adapter 18 is connected to the receiver 12. When a fire precursor is detected, a fire precursor detection signal is output to the wireless LAN adapter 18 and transmitted to a support server 30, which functions as a support device, via the wireless LAN base station 26 and the internet 28. The fire precursor detection signal includes predetermined terminal information such as the address of the fire detector 16 that was identified as a fire precursor and the district name indicating its installation location.

[0025] The support server 30 communicates with mobile phone terminals 20 such as smartphones via the internet 28, the mobile phone network 22, and the mobile phone base station 24.

[0026] The support server 30 has pre-registered the mobile device identification information of the mobile phone terminals 20 (20-1, 20-2, ...) carried by persons in charge of each fire-protected building where the fire alarm equipment 10 (10-1, 10-2, 10-3) is installed.

[0027] Those responsible for registering the mobile device identification information for mobile devices 20 (20-1, 20-2, ...) include disaster prevention managers and staff working at disaster prevention centers and management offices, security company staff who patrol fire-protected buildings, and disaster prevention personnel designated for each floor of companies and other organizations located in the building.

[0028] The support server 30 periodically sends a location information request signal specifying the registered mobile terminal identification information to collect location information from the mobile phone terminals 20 (20-1, 20-2, ...). The mobile phone terminals 20 are equipped with GPS functionality, and upon receiving a location information request signal from the support server 30, they activate their GPS functionality to detect the latitude and longitude of their current location as location information and transmit it to the support server 30.

[0029] When the support server 30 receives location information from a mobile phone terminal 20 (20-1, 20-2, ...), it compares it with location information of a predetermined equipment installation area including the fire alarm equipment 10 (10-1, 10-2, 10-3) and its vicinity. The server determines which mobile phone terminals 20 (20-1, 20-2, ...) have their detected location included in the equipment installation area, for example, mobile phone terminals 20-1 and 20-2 located near the fire alarm equipment 10-1, and transmits predetermined disaster prevention support information to store in advance.

[0030] The disaster prevention support information includes at least map information (floor maps, etc.) of buildings and other structures subject to fire prevention regulations, the district name indicating the address and installation location of the fire detector 16, and fire precursor response information indicating the actions to take when a fire precursor is detected. The fire precursor response information also includes instructions to confirm the installation site of the fire detector 16 that has been identified as a fire precursor and to transmit a response indicating whether there is a fire or not.

[0031] (Support through reception of fire warning signals) When the support server 20 receives a fire warning signal from the receiver 12, it obtains location information from pre-registered mobile phone terminals 20 (20-1, 20-2, ...), identifies, for example, mobile phone terminal 20-1 located at the fire alarm system 10-1 and, for example, mobile phone terminal 20-2 located nearby, and sends a support activation signal. Mobile phone terminals 20-1 and 20-2 then read out the disaster prevention support information they have stored and display it on their screens.

[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 identified as a fire precursor. Based on the location information of the fire point included in the support activation signal and the map information (floor map) of the building, etc., included in the disaster prevention support information stored in advance, the mobile phone terminals 20-1 and 20-2 display map information on their screens that shows the location of the fire point and their own location (mobile phone terminal 20-1 or 20-2).

[0033] This allows personnel carrying mobile phone terminals 20-1 and 20-2 to determine the location of the fire relative to their current location from the map information displayed on the screen, and simultaneously, based on the on-site confirmation instructions displayed on the screen, to go to the fire location to confirm whether it is a fire or not.

[0034] 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.

[0035] Personnel who have conducted on-site inspections transmit a fire confirmation signal or a non-fire confirmation signal to the support server 30 by touching the screen of their mobile phone terminals 20-1, 20-2, etc., and the support server 30 then transmits this signal to the receiver 12 of the fire alarm system 10-1.

[0036] When the receiver 12 receives a fire confirmation signal, it determines that a fire has been confirmed, as this corresponds to receiving a fire alarm signal via the push button operation of the transmitter, and performs the prescribed fire alarm operation, interlocking control, and alarm transfer control.

[0037] On the other hand, if the receiver 12 receives a non-fire confirmation signal, it stops the warning alarm associated with the preliminary fire determination and notifies that it is confirmed not to be a fire, and restores power based on the recovery operation performed by the person in charge.

[0038] [Mobile phone] (Mobile phone terminal configuration) As shown in Figure 2, the mobile phone terminal 20 is an example of a smartphone that also functions as a personal portable computer. The mobile phone control unit 32 of the mobile phone terminal 20 is implemented with an LSI equipped with a CPU, memory, and various input / output interfaces. It 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 detecting location information and transmitting response signals based on location information request signals from the support server 30, receiving and storing disaster prevention support information transmitted from the support server 30, and reading and displaying disaster prevention support information based on support activation signals transmitted from the support server 30.

[0039] The mobile phone communication unit 34 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).

[0040] The wireless LAN communication unit 36 ​​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 36 ​​also functions as a wireless LAN access point.

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

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

[0043] The display 44 uses a display device such as an LCD panel or an OLED panel, and a touch panel 46 is placed on the surface of the panel. The audio input / output unit 48 is equipped with a microphone, speaker, and audio codec to perform audio input and output.

[0044] The control unit 50 accepts user input via a keypad and control buttons and performs telephone control, etc. The memory card 52 is a removable external memory and is used for external storage of various data such as images captured by the camera unit 40.

[0045] (Disaster prevention support screen) As shown in Figure 3, the mobile phone terminal 20 displays the 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 warning message 56 that reads "Fire warning," followed by fire warning occurrence information 58, which includes the time of occurrence and the district name of the location (fire point).

[0046] Next, as instruction 60 for dealing with fire signs, an on-site inspection is ordered, followed by the display of map information 62. Map information 62 displays the fire point 64 and the operator's machine 66, showing the relative positions of the two. Personnel then proceed from the current position of their machine 66 to the fire point 64 to confirm 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. When a fire is confirmed, touching the fire confirmation button 70 sends a fire confirmation signal to the support server 30. 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 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.

[0048] [Operation of the disaster prevention support system] As shown in Figure 4, in step S1, the support server 30 periodically sends a location information request signal, for example, and in step S2, the mobile phone terminal 20 uses its GPS function to obtain latitude and longitude location information and sends it to the support server 30.

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

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

[0051] If the support server 30 determines that the location of the mobile phone terminal 20 acquired in step S10 is the 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. In step S16, if the receiver 12 receives a fire confirmation signal, it confirms the presence of a fire and activates the fire alarm. If it receives a non-fire confirmation signal, it stops the warning alarm, notifies that there is no fire, and restores the system based on the recovery operation.

[0053] [Modified version of the present invention] (Determining signs of a fire) Another form of determining a fire precursor is when the receiver 12 determines a malfunction precursor when the smoke concentration or temperature detected value from the fire detector 16 that is the target of the fire precursor reaches a predetermined fire determination value and initiates a predetermined storage operation.

[0054] Furthermore, as another method of determining a fire precursor, the rate of change of the smoke concentration detection value or temperature detection value of the fire detector 16 is determined, and when this rate of change reaches a predetermined preliminary fire determination change rate that is lower than the fire determination change rate, and predetermined fire precursor determination accumulation conditions are met, for example, when the rate of change exceeds the preliminary fire determination change rate for a predetermined number of consecutive times, a fire precursor may be determined.

[0055] (Fire alarm system) The above embodiment uses an R-type (Record-type) fire alarm system as an example, but a P-type (Proprietary-type) fire alarm system may also be used. A P-type fire alarm system monitors for fires on a circuit-by-circuit basis, and the receiver only needs to determine that a fire is imminent when it starts its fire detection and storage operation based on the circuit activation.

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

[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 includes any appropriate network configuration.

[0058] (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.

[0059] 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.

[0060] Furthermore, the receiver 12, upon receiving 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 displays the transmitter image on the screen. The response lamp lights up to indicate that the receiver 12 has received the message.

[0061] 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.

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