In a fire alarm system, for example, when the smoke density reaches a predetermined fire determination density, a fire signal is sent to a receiver to start accumulation operation, and a fire is determined to have occurred when a predetermined accumulation condition is met. However, before a fire is determined to have occurred, a precursor phenomenon of fire, such as a gradual increase in smoke density as in a smoldering fire, is observed. If this precursor phenomenon of fire can be detected before a fire is determined to have occurred, it becomes possible to deal with both fire and non-fire cases quickly and appropriately.

The present invention provides a disaster prevention support system that detects a precursor phenomenon of a fire using a fire detector and enables prompt and appropriate response through cooperation between the fire detector and a mobile terminal carried by a person concerned with a fire prevention object.

(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 system and the fire prevention object located in its surroundings, causing disaster prevention support information to be displayed. This allows the person involved in the fire alarm system or its surroundings to know the fire precursor determined by the fire detector and take appropriate measures, including on-site confirmation, at the stage of a fire precursor phenomenon.

In addition, the support activation signal from the fire detector is received by the mobile terminal of the fire alarm equipment where the fire detector that has been determined to be a sign of a fire is installed, or by the person concerned in the vicinity, and the support information is displayed and the on-site confirmation is carried out. This makes it possible to quickly take measures including:

(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 system will display the relative position of the fire that has been determined to be a sign of a fire and the relevant personnel's own device (their own mobile device) as map information on the screen, allowing them to accurately grasp the location of the fire and take appropriate action, such as checking the site.

(Effects of displaying the names of areas with signs of fire and information on how to deal with them)
In addition, the name of the area where the fire detector has been determined to be a fire warning signal and fire warning signal response information will be displayed on the mobile device of relevant personnel who are near the fire alarm system or in its vicinity, allowing them to know where the fire warning signal is located and take appropriate response action in accordance with the fire warning signal response information.

(Effects of on-site confirmation and response transmission)
In addition, the fire alarm equipment and related parties around it should check the scene according to the instructions of the fire warning information and respond to the fire detector with a fire confirmation signal if there is a fire, and a non-fire confirmation signal if there is no fire. Based on this, the fire detector sends a fire confirmed signal or a non-fire confirmed signal to the receiver, and the fire detector detects a fire alarm notification due to a confirmed fire or a non-fire notification due to a confirmed fire as a sign of a fire. This can be done once the decision has been made.

(Effects of acquiring disaster prevention support information)
In addition, disaster prevention support information specific to fire alarm equipment is acquired and stored in advance from a support device connected to a mobile terminal via a wide area network, and disaster prevention support information is transmitted when a fire detector detects a sign of a fire. It can be displayed appropriately.

(Effect of fire sign determination)
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 sign judgment accumulation conditions are met, it is judged as a fire sign, thereby reducing the possibility of a fire. It is possible to reliably detect high-level warning phenomena and determine them as fire warning signs.

(Effectiveness of fire detectors)
The fire detector of the present invention can be connected to a receiver via a conventional signal line, and can also be connected to a mobile terminal carried by a person concerned in the fire prevention object via a short-distance network, and can operate the fire alarm equipment by directly transmitting a required signal to the mobile terminal of the person concerned in the vicinity of the fire detector. Other features of the fire detector provide the same effects as those of the disaster prevention support system described above.

[First embodiment of disaster prevention support system]
(Fire alarm system)
As shown in FIG. 1, fire alarm systems 10 (10-1, 10-2, 10-3, ...) are installed in fire-protected structures such as buildings. As shown representatively in fire alarm system 10-1, fire detectors 16 are connected to signal lines 14 that are drawn from a receiver 12, for example, on a floor-by-floor basis in a building.

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 a mobile phone terminal 20 (20-1, 20-2, ...) such as a smartphone owned by a person involved in the fire prevention object, via a wireless LAN network that functions as a short-range network.

Here, the communication distance of the WiFi (registered trademark) network is about 100 meters, the communication distance of the Bluetooth (registered trademark) network is about 10 to 20 meters, and the fire alarm equipment 10 (10-1, 10-2, 10- In order to cover the entire area (3...) as a communication area, repeaters are installed as necessary.

In addition, people involved in fire prevention objects who carry mobile phone terminals 20 (20-1, 20-2, ...) include disaster prevention managers and disaster prevention personnel who work at disaster prevention centers and manager's rooms, and fire prevention personnel. This includes security company personnel who patrol the target property, and disaster prevention personnel designated for each floor by the companies that have moved into the building.

(Preliminary fire determination and fire determination)
The fire alarm system 10 of this embodiment is an R-type (Record-type) fire alarm system. 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 cycle, 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, for example, to hold the smoke density detection value or temperature detection value, 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 smoke density detection value or temperature detection value.

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 disables all signals being transmitted and received via the signal line 14.

The receiver 12, which has received the fire interrupt signal from the fire detector 16, 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 , sends an intra-group search command signal that sequentially specifies the sensor addresses within the searched group address, and sends the address of the fire sensor 16 that responded with a fire interrupt signal, that is, the address of the fire sensor 16 that was determined to be a preliminary fire. and output a cautionary warning (pre-alarm) indicating a preliminary fire.

Subsequently, when the smoke concentration detection value from the fire detector 16 that has determined that there is a preliminary fire reaches a predetermined fire determination value and satisfies a predetermined fire determination accumulation condition, the receiver 12 transmits the signal continuously for a predetermined number of times, for example. When the smoke concentration detection value exceeds the fire judgment value, it is determined that there is a fire, and a fire alarm is output by the main sound ringing or district sound ringing, as well as interlocking control of predetermined smoke prevention equipment, etc., and transfer notification to external equipment. Performs fire alarm operations including output.

(Identification of fire signs and disaster prevention support)
The fire detector 16 detects, for example, smoke concentration when a predetermined fire sign judgment accumulation condition is satisfied in a state where the smoke concentration detection value exceeds a preliminary fire judgment value of 3%/m which is lower than the fire judgment value of 10%/m. When the detected value exceeds the preliminary fire judgment value a predetermined number of times in succession, it is determined that it is a sign of a fire, and a support activation signal is transmitted from the antenna 18 to the mobile phone terminal 20 (20-1, 20-2, 20-2, etc.) via the wireless LAN network. ...). This support activation signal includes the address of the fire sensor 16 that has been determined to be a sign of a fire.

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

The support server 30 provides disaster prevention information including the equipment identifiers of the fire alarm equipment 10 (10-1, 10-2, 10-3, . . .) from the mobile phone terminals 20 (20-1, 20-2, . . .). When the support information transmission request signal is received, the disaster prevention support information corresponding to the fire alarm equipment 10 (10-1, 10-2, 10-3, etc.) corresponding to the equipment identifier is transmitted, and the mobile phone terminal 20 ( 20-1, 20-2,...) in advance.

The disaster prevention support information stored in advance in the mobile phone terminals 20 (20-1, 20-2, . . . ) includes map information (floor maps, etc.) of buildings, etc. that are subject to fire protection, addresses of fire detectors 16, etc. It includes at least the name of the district indicating the installation location, and fire sign response information indicating the countermeasures to be taken when a fire sign is determined.

The fire warning 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 warning and to transmit a response indicating whether or not there is a fire as a result of the check.

The mobile phone terminals 20 (20-1, 20-2, ...) that have received the support activation signal from the fire detector 16 use the position information of the fire point included in the support activation signal and the disaster prevention information stored in advance. Based on the map information of the building, etc. (floor map, etc.) included in the support information, map information showing the fire point and the own device (positions of the mobile phone terminals 20-1 and 20-2) is displayed on the screen. As a result, those involved can grasp the location of the fire point relative to the current location of the mobile phone terminal 20 (20-1, 20-2,...) from the screen display of the map information, and take actions to confirm the scene displayed on the screen at the same time. Based on instructions, you can go to the fire spot location and check the scene.

On-site confirmation of the location of the fire based on the fire warning signs is done by a human, 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 put out with a fire extinguisher, etc. On the other hand, if there is a non-fire factor, such as smoke or steam from cigarettes or cooking, it can be confirmed that there is no fire.

The relevant 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, ...).

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 a specified fire alarm operation, linkage control, and signal transfer control based on the fire confirmation.

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 caution alarm associated with the preliminary fire determination, and confirms that there is no fire. The receiver 12 is restored based on the restoration operation of the person in charge.

The fire detector 16 is provided with a detector control unit 45 using 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 Wi-Fi (registered trademark) or Bluetooth (registered trademark).

When the detector control section 45 determines that there is a preliminary fire, it instructs the transmission section 48 to transmit a fire interrupt signal to the receiver 12 via the signal line 14. In addition, when the sensor control unit 45 determines that there is a premonition of a fire in the state where a preliminary fire has been determined, the sensor control unit 45 sends a support activation signal from the antenna 18 via the wireless communication unit 50 to the mobile phone terminal 20 (20-1, 20-2,...).

Further, when the detector control unit 45 receives a fire confirmation signal from the mobile phone terminal 20 (20-1, 20-2, etc.) in FIG. Sends a fire confirmation signal to aircraft 12.

In addition, when the detector control unit 45 receives a non-fire confirmation signal from the mobile phone terminal 20 (20-1, 20-2, ...) 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.

The operation unit 70 receives user operations using a keypad or operation buttons to perform telephone control and the like. 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.

(Disaster prevention support screen)
As shown in FIG. 4, when the mobile phone terminal 20 receives the support activation signal from the fire detector 16, it displays the disaster prevention support screen 74. The disaster prevention support screen 74 displays the time of occurrence and the district name of the place of occurrence (point of fire) as fire precursor occurrence information 78, following a fire predictor warning message 76 of "This is a fire predictor."

Next, an instruction to check the scene is given as a fire warning response instruction 80, and then map information 82 is displayed. The map information 82 displays the flash point 84 and the own aircraft 86, and by knowing the positional relationship between the two, the person concerned can go to the flash point 84 from the current position of the own aircraft 86 and check the scene to determine whether there is a fire or not. .

Subsequently, a response response instruction 88, a fire confirmation button 90, and a non-fire confirmation button 92 are provided, and when a fire is confirmed, when the fire confirmation button 90 is touched, a fire confirmation signal is sent to the fire detector 16 that has determined that it is a sign of a fire. However, when it is confirmed that there is no fire, when the non-fire confirmation button 92 is touched, a non-fire confirmation signal is sent to the fire sensor 16 that has determined that there is a sign of a fire. Note that when the fire confirmation button 90 is touched to transmit a fire confirmation signal, the location of fire extinguishing equipment such as a fire extinguisher and a fire hydrant may be displayed on the map information 82 to support initial fire extinguishment.

[Operation of Disaster Prevention Support System]
As shown in Figure 5, in step S1, the mobile phone terminal 20 makes a request to send disaster prevention support information specifying the equipment identifier of the fire alarm equipment 10 in which 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.

The receiver 12 performs a polling (calling) in which the batch AD conversion command with a 1-minute cycle and the sensor address are sequentially specified in step S4, and in response to this, the fire detector 16 detects smoke concentration or temperature in step S5. The signal is AD converted and held as a detected value, and the detected value is responded to polling.

When 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 warning alarm.

When the fire detector 16 determines in step S10 that a fire is present because a certain fire warning accumulation condition is met, it sends a support activation signal to the mobile phone terminal 20 in step S11.

The mobile phone terminal 20 that has received the support activation signal displays disaster prevention support information on the disaster prevention support screen 74 shown in FIG. 4 in step S12 to instruct the user to check the site, and in step S13 transmits a fire confirmation signal or a non-fire confirmation signal to the fire detector 16 that has been determined to be a fire precursor based on the confirmation response operation for fire or non-fire.

When the fire detector 16 receives a fire confirmation signal in step S14, 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.

In step S15, the receiver 12 confirms a fire and performs a fire alarm operation as a reception operation in response to the fire confirmation signal, and stops a caution alarm accompanying a preliminary fire determination as a reception operation in response to a non-fire confirmation signal. to notify non-fires and recover based on recovery operations.
