Description

Technical Field

[0001] The present invention relates to a disaster prevention information display device that widely monitors fire alarm equipment provided with a receiver and fire detectors.

Background Art

[0002] Conventionally, as fire alarm equipment that monitors fires by connecting fire detectors to signal lines led out from a receiver, so-called R-type (Record type) fire alarm equipment is known.

[0003] In R-type fire alarm equipment, analog fire detectors with a transmission function assigned unique addresses are connected to the signal lines led out from the receiver. When analog data such as smoke density or temperature reaches a predetermined caution level, based on a fire interrupt from the fire detector, the receiver issues a search command to identify the address of the fire detector that issued the alarm, centrally collects the analog data, determines that a fire has occurred when the analog data reaches a predetermined fire level, lights the fire representative lamp of the receiver to output an audible alarm, and further displays the terminal that detected the fire on a display or the like The end address is displayed.

[0004] In this way, when the address of the fire detector that detected the fire is known, appropriate evacuation guidance and fire extinguishing activities become possible, which is an indispensable function especially for fire monitoring of large-scale facilities.

[0005] In addition, control terminal devices such as fire doors and fire dampers are connected to the signal lines led out from the receiver of the R-type fire alarm equipment via repeaters with transmission functions. In the event of a fire, the control signal from the receiver releases the holding of the fire door to close it, and performs smoke prevention and exhaust control that opens the fire damper to discharge smoke.

[0006] Furthermore, the receiver of the fire alarm system is connected to a fire prevention display device. When a fire is detected, the display of the fire prevention display device shows a floor plan of the area where the fire occurred, for example, the floor on which the fire occurred. The location of the fire is indicated by a flashing red alarm symbol at the location of the fire detector on the floor plan, allowing for quick and safe evacuation guidance and support for firefighting activities by confirming the location of the fire. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2007-219870 [Patent Document 2] Japanese Patent Publication No. 2017-191418 [Patent Document 3] Japanese Patent Publication No. 2018-180579 [Patent Document 4] Japanese Patent Publication No. 61-076000 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, with conventional fire alarm systems, the receiver has an automatic notification function that notifies external organizations such as fire departments and security companies of the occurrence of a fire. However, the external organizations that receive the automatic notification must contact the facility that received the notification to confirm the fire, find the address of the fire's location, and take action. This process is time-consuming and complicated because the fire information from the fire alarm system is insufficient.

[0009] Furthermore, in recent years, residential fire alarm systems that monitor fires by installing wirelessly connected fire alarms in homes have become widespread. However, residential fire alarm systems also have a similar problem: if they use an automatic notification function to notify external organizations such as security companies of fire occurrences, the response process can be time-consuming and cumbersome.

[Effects of the Invention]

[0022] (Basic effects) The present invention relates to a wide-area disaster prevention monitoring system that receives and displays fire occurrence information from a fire alarm system, wherein a predetermined device that is communicated with the fire alarm system via a predetermined network is provided with a disaster prevention information display control unit that, when fire occurrence information is received from the fire alarm system, displays a map on the screen including the fire occurrence facility where the fire alarm system is installed and displays the fire occurrence facility in an identifiable manner, when a selection operation for the fire occurrence facility is detected, displays the floor of the fire occurrence facility and displays the fire occurrence floor within that floor in an identifiable manner, and when a selection operation for the fire occurrence floor is detected, displays a floor map of the fire occurrence floor and displays the fire occurrence area on the floor map in an identifiable manner. When a device such as a fire alarm system receives fire information, it displays the location of the fire, such as a building, on a map, making it identifiable. This allows fire department personnel to intuitively understand where the fire is occurring in their area of ​​responsibility from the map screen and take appropriate action. Furthermore, by tapping to select the fire location, the floor on which the fire occurred is displayed, allowing for appropriate decisions regarding firefighting activities and evacuation guidance. Additionally, by tapping to select the floor on the floor display, the fire-affected section is displayed on the floor map, providing a detailed understanding of the fire site and enabling quick and appropriate decision-making and response.

[0023] (Effects of house fires) Furthermore, when the disaster prevention information display control unit identifies a residential fire based on fire occurrence information received from the fire alarm system, and detects the user's selection operation for the fire-affected house on the map, it displays the floor plan of the fire-affected house and also displays the fire-affected area on the floor plan in an identifiable manner. Therefore, when fire occurrence information is received from a residential fire alarm system that has wirelessly interconnected fire alarms installed in the house, unlike fire alarm systems for buildings, it is not necessary to display the floor where the fire occurred. Thus, by immediately displaying the floor plan of the house as soon as the user's selection operation for the fire-affected house on the map is detected, the location of the fire in the house can be identified, enabling appropriate judgment and response to the residential fire.

[0024] (Effect of the fire alarm symbol) Furthermore, by placing designated fire markers in the facilities and sections where fires have occurred, they can be clearly identified, and selection operations can be performed using these designated fire markers, making it possible to more intuitively understand and respond to the presence of a fire.

[0025] (Effect of hierarchical display) Furthermore, the disaster prevention information display control unit, upon detecting the selection of a fire-affected facility or a fire-affected marker placed on it, displays the floor level of the fire-affected facility as a pop-up, and color-codes the floor where the fire occurred within that facility's floor level. As a result, the floor levels of facilities with colored fire-affected floors are displayed on the map screen corresponding to the fire-affected facility or the fire-affected facility where the fire-affected marker is placed, allowing for easy and reliable identification of the fire-affected floor and enabling appropriate decision-making and response.

[0026] (Effect of facility information) Furthermore, the wide-area disaster prevention monitoring system has been modified to display designated facility information for the fire-affected facility when it detects the selection of a designated fire-affected area or a designated fire-affected marker placed within that area. This allows for quick acquisition of information about the fire-affected facility through screen operation, enabling appropriate decision-making and response.

[0027] (Effect of facility information) Furthermore, the disaster prevention information display control unit is configured to display information that includes at least the address and contact information of the fire-affected facility as designated facility information. This allows users to easily and quickly obtain at least the address and contact information, such as a telephone number, through screen operation, enabling them to confirm the fire and take appropriate action.

[0028] (Effectiveness of devices that control the display of disaster prevention information) Furthermore, the designated device for controlling the display of disaster prevention information includes a server, mobile terminal, and mobile phone terminal that are connected to the fire alarm system via a designated network. By providing the necessary device with the function of a disaster prevention information display control unit, and by setting each device as a destination for fire occurrence information in the fire alarm system, it is possible to inform external organizations and individuals involved in the fire about the fire situation using map information, enabling them to quickly and easily grasp the fire situation and take the necessary actions and make decisions.

[0029] (Wide-area disaster prevention monitoring methods) Another embodiment of the present invention is a wide-area disaster prevention monitoring method for receiving and displaying fire occurrence information from a fire alarm system. A disaster prevention information display control unit installed in a predetermined device, which is communicated with the fire alarm system via a predetermined network, displays a map on the screen including the fire-occupied facility where the fire alarm system is installed, and displays the fire-occupied facility in an identifiable manner when it receives fire occurrence information from the fire alarm system. When it detects a selection operation for the fire-occupied facility, it displays the hierarchy of the fire-occupied facility and displays the fire-occupied floor within that hierarchy in an identifiable manner. When it detects a selection operation for the fire-occupied floor, it displays a floor map of the fire-occupied floor and displays the fire-occupied section of the floor map in an identifiable manner. As a result, the same effects as the wide-area disaster prevention monitoring system described above can be obtained. Furthermore, the effects of other features in the wide-area disaster prevention monitoring method are the same as the effects of the corresponding features in the wide-area disaster prevention monitoring system described above.

[0042] Furthermore, in the following explanation, "fire alarm systems installed in large buildings, etc." is simply referred to as "fire alarm systems," and the display by the disaster prevention information display control unit is referred to as "disaster prevention information display."

[0043] [Specific details of the embodiment] The specific details of the implementation of the wide-area disaster prevention monitoring system will be explained in more detail. The details will be explained in the following sections. a. Wide-area disaster prevention monitoring system b. Receiver Functional Configuration b1. Function b2.Fire monitoring control c. Server Functional Configuration d. Disaster prevention information display d1. Disaster prevention information display in buildings (large buildings, etc.) d2. Disaster prevention information display in homes e. Server-based control of disaster prevention information display f. Modified versions of the present invention

[0044] [a. Wide-area disaster prevention monitoring system] As shown in Figure 1, the server 28 of this embodiment monitors one or more fire alarm systems 1 installed in buildings such as office buildings and large stores, and one or more residential fire alarm systems 100 installed in residences.

[0045] The fire alarm system 1 includes a receiver 10, for example, an R-type (Record type), installed in the building's manager's office or disaster prevention center. Signal lines 12-1 and 12-n are drawn from the receiver 10 to the protected area, separated by system. Multiple analog fire detectors 14, each with a unique address set as terminal identification information and possessing transmission capabilities, are connected to line 12-1 to monitor for fires. Additionally, an addressable transmitter 15, also with a unique address and transmission capabilities, is connected to signal line 12-1 and transmits a fire alarm signal via push-button operation.

[0046] Signal line 12-n is connected to fire doors, smoke control equipment 18 such as smoke dampers, etc., via a repeater 16 with a transmission function to which a unique address has been set. In addition, gas leak detectors, gas shut-off valves, etc., are also connected to the signal line via a repeater 16 with a transmission function to which a unique address has been set, but these are not shown in the diagram. Note that signal lines 12-1 and 12-n may be referred to as signal line 12 when there is no need to distinguish between them.

[0047] The receiver 10 is equipped with a gateway device 24. When the receiver 10 detects a fire, it transmits fire information, including a predetermined equipment ID, from the gateway device 24 to the server 28 via the internet 26.

[0048] Furthermore, the receiver 10 is equipped with a disaster prevention display device 20 via a transmission line 22, which displays all events, including fire alarms, processed by the receiver 10.

[0049] The residential fire alarm system 100 is equipped with one or more wireless interconnected fire alarms 102. When any of the fire alarms 102 detect a fire, it outputs a fire alarm and transmits a fire interconnection signal to the other fire alarms 102 to output an interconnection alarm. The residential fire alarm system 100 is also equipped with an adapter 104 and a gateway device 24. When the adapter 104 receives a fire interconnection signal from any of the fire alarms 102, it performs a protocol conversion and transmits fire occurrence information, including the equipment ID, from the gateway device 24 to the server 28 via the internet 26.

[0050] When server 28 receives fire information from fire alarm equipment 1, it retrieves map information from map information database 30 and displays a map on the screen that includes the building where the fire occurred and other facilities where fire alarm equipment 1 is installed. Server 28 also places a predetermined fire marker on the building where the fire occurred on the map. When it detects a selection operation by tapping the fire marker placed on the building where the fire occurred, it displays the building's floors in a pop-up window and highlights the floor where the fire occurred within those floors. When it detects a selection operation by tapping the floor where the fire occurred within the floor display, it displays a floor map of that floor and places a predetermined fire marker in the fire-affected area on the floor map. Furthermore, when it detects a selection operation by tapping the fire marker placed in the fire-affected area, it controls the display of facility information such as the address and contact information of the building where the fire occurred.

[0051] Furthermore, when the server 28 receives fire occurrence information from the residential fire alarm system 100 and identifies the residential fire from the system ID, it retrieves map information from the map information database 30 and detects the fire occurrence. The system displays a map on the screen that includes the house where the fire occurred, which is equipped with the residential fire alarm system 100 that transmitted the information. It also places a fire marker on the house where the fire occurred. When it detects that the fire marker on the house where the fire occurred has been tapped, it displays a floor plan of the house, which is a floor map of the house where the fire occurred, and places a predetermined fire marker in the fire-affected area of ​​the floor plan. When it detects that the fire marker on the fire-affected area has been tapped, it controls the system to display facility information such as the address and contact information of the house where the fire occurred.

[0052] Furthermore, a mobile phone terminal 34 communicates with the server 28 via, for example, a mobile phone network 32, and a tablet terminal 38, etc., communicates with the server 28 via a wide-area wireless LAN communication network 36 such as a WiFi (registered trademark) network, and is able to download screen information created by the disaster prevention information display control of the server 28 and view it in the same way as the server 28.

[0053] [b. Receiver Functional Configuration] (b1. Function) Figure 2 is a block diagram showing the functional configuration of the receiver and server of the fire alarm system. As shown in Figure 2, the receiver 10 of the fire alarm system 1 is composed of a computer circuit equipped with a CPU, memory, various input / output ports, etc., and is provided with a main CPU 40 and multiple sub-CPU boards 42, with sub-CPUs 44 and transmission units 46 provided on the sub-CPU boards 42. The main CPU 40 and the sub-CPUs 44 are connected by an internal communication line 45 and send and receive data to and from each other.

[0054] The main CPU 40 is connected to a touch panel display 47 using an LCD display panel or the like, a display unit 48 using indicator lights such as LEDs, an operation unit 50 equipped with various switches such as a fire detection switch, a main sound stop switch, and a district sound temporary stop switch, an audible alarm unit 52 equipped with a speaker, a transmission unit 54, and a transmission unit 55.

[0055] Furthermore, the main CPU 40 is equipped with the functions of a receiver control unit 56, which are realized through the execution of a program.

[0056] (b2.Fire monitoring control) The sub-CPU 44 on the sub-CPU board 42 provided in the receiver 10 shown in Figure 2 performs fire monitoring and control by instructing the transmission unit 46 to send and receive signals to and from the fire detector 14 connected to the signal line 12-1 according to a predetermined communication protocol.

[0057] During normal monitoring, the sub-CPU 44 instructs the transmission unit 46 at regular intervals to send a broadcast batch AD conversion signal including a batch AD conversion command. Upon receiving this batch AD conversion signal, the fire detector 14 detects and stores the smoke concentration or temperature as sensor data. Subsequently, the sub-CPU 44 sends a call signal including a polling command that sequentially specifies terminal addresses.

[0058] When the fire detector 14 receives a call signal with an address matching its own address, it transmits a response signal containing the sensor data it holds at that time to the transmission unit 46 of the receiver 10. In addition, when the smoke concentration or temperature exceeds a predetermined fire alert level, the fire detector 14 transmits a fire interrupt signal to the transmission unit 46 of the receiver 10.

[0059] When the sub-CPU 44 receives a fire interrupt signal via the transmission unit 46, it sends a group search command signal to identify the group containing the fire detector 14 that has detected the fire, and then sends an in-group search command signal to identify the address of the fire detector 14 that has detected the fire, centrally collects the analog data from the sensor, and transmits it to the main CPU 40 via the internal communication line 45.

[0060] The main CPU 40 compares the analog data received from the sub-CPU 44 with a predetermined fire detection level that is higher than the fire warning level. When the analog data reaches the fire detection level, it determines that there is a fire, lights up the fire indicator light on the display unit 48, outputs a predetermined audible alarm from the speaker of the audible alarm unit 52 to indicate the occurrence of a fire, displays fire information including the location of the fire on the display 47 based on the terminal address where the fire was detected, and further outputs a fire alarm signal to the outside via the alarm transfer unit 54 to perform predetermined alarm transfer control, etc.

[0061] The main CPU 40 is connected to the disaster prevention display device 20 via the transmission unit 55. The disaster prevention display device 20 has the function of displaying all events, including fire alarms, processed by the receiver control unit 56 of the receiver 10 on the display 47. In particular, it stores floor plans of buildings that are designated as warning areas, and when the receiver 10 determines that there is a fire, it displays a floor plan of the floor where the fire occurred based on the terminal address of the fire detector 14 that detected the fire, and also performs display control to indicate the location of the fire detector 14 that detected the fire within the floor plan of the floor where the fire occurred, for example by flashing red as an alarm symbol.

[0062] Therefore, the disaster prevention display device 20 has pre-registered plan view location information that indicates the coordinate position on the warning area plan view, associated with the terminal address of the fire detector 14.

[0063] [c. Server Functional Configuration] As shown in Figure 2, the server 28 is composed of a computer circuit equipped with a CPU, memory, various input / output ports, etc., and includes a communication control unit 58, a server control unit 60, an operation unit 62 such as a keyboard and mouse, a display unit 64 using a display, and a storage unit 66.

[0064] The server control unit 60 is equipped with the function of a disaster prevention information display control unit 70, which collects or generates equipment information for the fire alarm system 1 and the residential fire alarm system 100 and stores it in the storage unit 66.

[0065] Figure 3 is an explanatory diagram showing the record format of the equipment information. As shown in Figure 3, the equipment information 68 includes equipment ID, location information, floor map information, facility information, and contact information. The equipment ID is identification information to distinguish between fire alarm system 1 or residential fire alarm system 100. The location information is the latitude and longitude indicating the location of fire alarm system 1 or residential fire alarm system 100, making it possible to identify the location on a map.

[0066] The floor map information is a floor plan showing the floor levels in buildings and other facilities, and a floor plan showing the layout of the house in residential buildings. The facility information includes the address and contact telephone number of the fire alarm system 1 and the residential fire alarm system 100. Furthermore, the contact information includes the URLs of the mobile phone terminals 34 and tablet terminals 38 to which the disaster prevention information to be displayed and controlled will be distributed.

[0067] Referring again to Figure 2, when the disaster prevention information display control unit 70 of the server 28 receives fire occurrence information from the receiver 10, including the equipment ID and the terminal address based on the fire detection by the fire detector 14, it obtains equipment information of the fire alarm equipment 1 corresponding to the received equipment ID from the storage unit 66, obtains a map of a predetermined scale, for example, including the location of the building where the fire occurred, from the map information database 30 based on the building location information extracted from the equipment information, displays the map screen on the display of the display unit 64, and places a predetermined fire occurrence mark on the building where the fire occurred on the map screen.

[0068] Furthermore, when the disaster prevention information display control unit 70 detects a selection operation by tapping a fire occurrence mark placed on a building where a fire has occurred on the map, it performs control to display the floor of the building where the fire occurred in a pop-up window and color-codes the floor where the fire occurred for identification.

[0069] Furthermore, when the disaster prevention information display control unit 70 detects a tap operation to select a colored fire-occurring floor within the hierarchy, it displays a floor map of the fire-occurring floor and controls the placement of a predetermined fire occurrence mark in the fire-occurring section of the floor map.

[0070] Furthermore, when the disaster prevention information display control unit 70 detects a selection operation by tapping the fire occurrence mark on the floor map, it controls the display of facility information for the building where the fire occurred, such as the address and contact information.

[0071] Meanwhile, when the disaster prevention information display control unit 70 of the server 28 receives fire occurrence information, including the equipment ID and the terminal address based on the fire detection of the wirelessly linked fire alarm 102, from the residential fire alarm system 100 shown in Figure 1, it obtains equipment information of the residential fire alarm system 100 corresponding to the received equipment ID from the storage unit 66, obtains a map of a predetermined scale including the location of the fire-affected house from the map information database 30 based on the location information of the fire-affected house extracted from the equipment information, displays the map screen on the display of the display unit 64, and places a predetermined fire occurrence mark on the fire-affected house on the map screen.

[0072] Furthermore, when the disaster prevention information display control unit 70 detects a tap operation to select a fire occurrence mark placed on a fire-affected house displayed on the display, it does not perform a hierarchical display, but instead displays a floor plan of the fire-affected house and controls the placement of a predetermined fire occurrence mark in the fire-affected area of ​​the floor plan. In addition, when the disaster prevention information display control unit 70 detects a tap operation to select a fire occurrence mark on the floor plan, it controls the display of facility information for the fire-affected house, such as the address and contact information.

[0073] [d. Disaster prevention information display] Figure 4 is an explanatory diagram showing a map screen displayed based on fire occurrence information for a building fire; Figure 5 is an explanatory diagram showing a map screen where the floor of the building where the fire occurred is displayed by selecting the fire occurrence mark in Figure 4; Figure 6 is an explanatory diagram showing a floor map screen displayed by selecting the floor where the fire occurred in the floor display in Figure 5; and Figure 7 is an explanatory diagram showing a floor map screen where facility information is displayed by selecting the fire occurrence mark placed in the fire occurrence area in Figure 6.

[0074] (d1. Disaster prevention information display in buildings (large buildings, etc.)) When the server 28 in Figure 2 receives fire occurrence information, including the equipment ID and the terminal address based on the fire detection by the fire detector 14, from the receiver 10 of the fire alarm system 1, it displays the map screen 72-1 shown in Figure 4. The map on the map screen 72-1 is at a predetermined scale that includes the fire-occupied facility (fire-occupied building) 74, and a fire occurrence mark 76 is placed on the building that is the fire-occupied facility 74. The map scale can be changed to any scale using the scale 75.

[0075] When the fire occurrence mark 76 is selected by tapping on the map screen 72-1 in Figure 4, the map screen 72-2 in Figure 5 is displayed. In the map screen 72-2 in Figure 5, a floor display section 78 pops up next to the fire occurrence mark 76 placed on the fire-affected facility 74, and the fire-affected floor 80 is identified by color.

[0076] In the map screen 72-2 of Figure 5, tapping to select the fire-occurring floor 80 within the hierarchical display 78 displays the floor map screen 82-1 of Figure 6. The floor map screen 82-1 of Figure 6 displays a floor map (floor plan) that divides the fire-occurring floor into sections, and a fire occurrence mark 76 is placed in the fire-occurring section 86.

[0077] On the left side of the floor map screen 82-1, the floor indicator 78 is displayed, and the floor where the fire occurred (80) is highlighted in color. By tapping on any floor in this floor indicator 78, the floor map of the selected floor will be displayed.

[0078] Additionally, a reduced floor map 90 is displayed on the left side of the floor map screen 82-1, with the display area 90a within it being displayed as the floor map 84. By scrolling the display area 90a, the floor map 84 can be moved left and right.

[0079] When the fire occurrence mark 76 is selected by tapping on the floor map screen 82-1 in Figure 6, the floor map screen 82-2 shown in Figure 7 is displayed. In the floor map screen 82-2 in Figure 7, for example, facility information 94 is displayed above the floor map 84, and in this example, the address, facility name, and contact telephone number are displayed.

[0080] Additionally, the hierarchical display section 78 is displayed, and a photograph 92 of the building that is the subject of facility information 94 is displayed in the upper left of the floor map screen 82-2.

[0081] (d2. Disaster prevention information display in homes) Figure 8 is an explanatory diagram showing a map screen displayed based on fire occurrence information for a residential fire, and Figure 9 is an explanatory diagram showing a floor map screen of a house displayed by selecting the fire occurrence mark in Figure 8.

[0082] When the server 28 in Figure 2 receives fire occurrence information from the residential fire alarm system 100, including the system ID and the terminal address based on the fire detection by the fire alarm 102, it displays the map screen 72-11 shown in Figure 8. The map on the map screen 72-11 is at a predetermined scale that includes the fire-affected house which is the fire-affected facility 74, and a fire occurrence mark 76 is placed on the fire-affected house which is the fire-affected facility 74.

[0083] When you tap to select the fire occurrence mark 76 on the map screen 72-11 in Figure 8, the floor map screen 82-11 in Figure 9 is displayed. The floor map screen 82-11 in Figure 8 displays the floor plans of the first and second floors of the house where the fire is occurring as the floor map 84-11, and the fire occurrence mark 76 is placed in the fire-affected section 86, for example, the living room.

[0084] On the left side of the floor map screen 82-11, facility information for the residence 94-11 is displayed. In this example, the address, facility name, and contact phone number are shown. Additionally, a photograph of the residence where the fire occurred 92-11 is displayed in the upper left corner of the floor map screen 82-11.

[0085] [e. Server-based control of disaster prevention information display] Figure 10 is a flowchart showing the control of disaster prevention information display by the server in Figure 2. As shown in Figure 10, when the server 28 receives fire occurrence information from the fire alarm system in step S1, it proceeds to step S2, where it obtains map information including the fire-occupied facility, such as a building, and in step S3 displays a map with fire occurrence markers placed on the fire-occupied facility.

[0086] Next, server 28 proceeds to step S4, and upon detecting the selection of the fire occurrence marker on the map screen, proceeds to step S5, where it displays the identified floor by coloring the floor where the fire occurred.

[0087] Next, server 28 proceeds to step S6, and upon determining the selection of the fire-affected floor, proceeds to step S7, where it displays a floor map with fire markers placed in the fire-affected area.

[0088] Next, server 28 proceeds to step S8, and upon determining that a fire marker placed in the fire-affected area has been selected, proceeds to step S9, where facility information is displayed in the corner of the floor map screen. Server 10 then repeats the process from step S1 until a termination operation is determined in step S10.

[0089] Furthermore, if fire information is received from the residential fire alarm system in step S1, when the server 28 determines in step S4 that a fire marker has been selected for the house where the fire occurred on the map, it skips steps S5 and S6 and proceeds to step S7 without performing hierarchical display, and controls the system to display a floor plan of the house with the fire marker placed in the fire-affected area.

[0090] [f. Variations of the present invention] (Map screen of the facility where the fire occurred) In the above embodiment, for example, as shown in Figure 4, when the server receives a fire alarm signal from the fire alarm system, it displays a map screen 72-1 with a fire alarm mark 76 placed at the fire-affected facility 74. In addition to this, facilities with a high risk of fire (e.g., gas stations, etc.) or facilities that require priority evacuation guidance (e.g., hospitals, schools, elderly care facilities, etc.) located in the vicinity of the fire-affected facility 74 may be pre-configured, and warning marks indicating the high risk of fire or priority for evacuation guidance may be placed around the fire-affected facility 74 in addition to the fire alarm mark 76.

[0091] (Disaster prevention information display control) The above embodiment uses a server to control the display of disaster prevention information for various fire alarm systems. However, it is not limited to this, and the disaster prevention information display control of this embodiment may also be performed using a mobile phone terminal or tablet terminal that is connected to the various fire alarm systems to be monitored via a network. In this case, it is desirable that the equipment information of the various fire monitoring systems be stored on a server with a large memory capacity, and that the mobile phone terminal or tablet terminal retrieves the facility information from the server when it receives fire occurrence information from the various fire alarm systems and performs disaster prevention information display control.

[0092] (Fire alarm system) The above embodiment uses a fire alarm system in which R-type fire detectors are connected via a signal line from an R-type receiver as an example. However, a fire alarm system in which an addressable transmitter equipped with an address setting and transmission function is connected to a detector line drawn from a P-type (Proprietary-type) receiver can also be included as a target of monitoring according to this embodiment.

[0093] Furthermore, a fire alarm system that monitors fires by communicating wireless fire detectors to the receiver via a wireless line can also be included in the monitoring targets of this embodiment by connecting it to the server via a gateway device.

[0094] Furthermore, in apartment buildings with a floor area of ​​less than 500 square meters, there is no obligation to install automatic fire alarm systems, and residential fire alarms are installed. For example, a specific small-scale fire alarm system in which wireless interconnected fire alarms are installed and interconnected in each room of an apartment building can also be included as a target of monitoring under this embodiment by communicating with the server via an adapter and gateway device, similar to residential fire alarm systems.

[0095] (others) Furthermore, the present invention is not limited to the embodiments described above, and includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values ​​shown in the embodiments described above.
