Description

[Technical Field]

[0001] The present invention relates to a disaster prevention information display device that monitors a wide area of ​​a fire alarm system equipped with a receiver and a fire detector. [Background technology]

[0002] BACKGROUND ART Conventionally, a so-called R-type (Record type) fire alarm system has been known as a fire alarm system that monitors fires by connecting a fire detector to a signal line drawn from a receiver.

[0003] In the case of an R-type fire alarm system, an analog fire detector with a transmission function and a unique address set is connected to the signal line drawn from the receiver, and when analog data such as smoke density or temperature reaches a predetermined warning level, the receiver issues a search command based on a fire interrupt from the fire detector, identifies the address of the fire detector that triggered the alarm, and collects analog data intensively. When the analog data reaches a predetermined fire level, it determines that there is a fire, turns on the fire representative light on the receiver, outputs an audible alarm, and further displays the information of the terminal that detected the fire on a display, etc. The last address is displayed.

[0004] In this way, knowing the address of the fire detector that detected the fire makes it possible to provide appropriate evacuation guidance and firefighting activities, making this a function that is essential especially for fire monitoring in large-scale facilities.

[0005] In addition, the signal line drawn from the receiver of the R-type fire alarm system is connected to control terminal equipment such as fire doors and fire dampers via a repeater with transmission capabilities, and in the event of a fire, a control signal from the receiver releases the hold on the fire doors and closes them, and also opens the fire dampers to discharge smoke, thereby performing smoke control and exhaust control.

[0006] In addition, a disaster prevention display device is connected to the receiver of the fire alarm system, and when a fire is detected, the display of the disaster prevention display device shows the area where the fire occurred, for example, a floor plan of the floor where the fire occurred, and an alarm symbol indicating the location of the fire, for example, flashes red, at the position of the fire detector that detected the fire on the floor plan, making it possible to confirm the location of the fire and provide quick and safe evacuation guidance and support through firefighting activities.

[Effects of the Invention]

[0022] (Basic effect) The present invention relates to a wide-area disaster prevention monitoring system that receives and displays fire occurrence information from a fire alarm system, and a disaster prevention information display control unit is provided in a predetermined device that is connected to the fire alarm system via a predetermined network, and when fire occurrence information is received from the fire alarm system, the disaster prevention information display control unit displays a map including the facility where the fire alarm system is installed on a screen and identifiably displays the facility where the fire occurred, and when a selection operation for the facility where the fire occurred is determined, the disaster prevention information display control unit displays the floor of the facility where the fire occurred and identifiably displays the floor where the fire occurred within the floor, and when a selection operation for the floor where the fire occurred is determined, the disaster prevention information display control unit displays a floor map of the floor where the fire occurred and identifiably displays the section where the fire occurred on the floor map, thereby enabling a server provided external to the fire alarm system to display the disaster prevention information. When a device such as a fire alarm receives fire information from a fire alarm system, the facility where the fire occurred, for example a building, is displayed on a map in an identifiable manner, allowing personnel from the fire department, etc. to intuitively understand from the map screen where the fire occurred in their area of ​​jurisdiction and take appropriate action. Furthermore, when the facility where the fire occurred is selected by tapping, a hierarchy display is displayed identifying the floor in the building on which the fire occurred, and by knowing which floor of the building the fire is on, it is possible to make appropriate decisions and take appropriate action such as firefighting activities and evacuation guidance. Furthermore, when the floor on the hierarchy display where the fire occurred is selected by tapping, the section where the fire occurred is displayed in an identifiable manner on the floor map, allowing personnel to understand the situation at the fire site in detail and enabling quick and appropriate decisions and action to be taken.

[0023] (Effects of house fires) In addition, when the disaster prevention information display control unit identifies a residential fire based on fire information received from a fire alarm system, when it determines that the user has selected the house where the fire occurred, which is the facility where the fire occurred on the map, it displays a floor plan of the house where the fire occurred and also displays the area where the fire occurred in an identifiable manner on the floor plan.Therefore, when fire information is received from a residential fire alarm system in which a wirelessly linked fire alarm or the like is installed in the house as a fire alarm system, there is no need to display the floor where the fire occurred, as is the case with fire alarm systems in buildings, etc., so by immediately displaying a floor map showing the floor plan of the house once it determines that the user has selected the house where the fire occurred on the map, it is possible to identify the location of the fire in the house and make appropriate decisions and take appropriate measures against the residential fire.

[0024] (Effect of fire outbreak mark) In addition, a designated fire outbreak mark is placed on the facility and area where the fire occurred to make them identifiable, and selection operations can be performed using the designated fire outbreak mark, making it possible to more intuitively understand that a fire has occurred and take action.

[0025] (Effect of hierarchical display) In addition, when the disaster prevention information display control unit determines that a selection operation has been performed on a facility where a fire has occurred or a fire outbreak mark placed on a facility where a fire has occurred, it pops up the floor of the facility where the fire has occurred and displays the floor where the fire has occurred in that floor in a different color.Therefore, the floor of the facility where the fire has occurred is displayed in a different color corresponding to the facility where the fire has occurred or the facility where the fire outbreak mark has been placed on the map screen, allowing the user to easily and reliably grasp the floor on which the fire has occurred and make appropriate decisions and take appropriate action.

[0026] (Effect of facility information) Furthermore, the wide-area disaster prevention monitoring system is also designed to display specified facility information about the facility where the fire occurred when it determines that a selection operation has been performed on the fire area or a specified fire outbreak mark placed in the fire area, allowing information about the facility where the fire occurred to be quickly obtained by operating the screen, allowing appropriate judgment and response.

[0027] (Effect of facility information) In addition, the disaster prevention information display control unit is configured to display information including at least the address and contact information of the facility where the fire occurred as specified facility information for the facility where the fire occurred, so that by operating the screen, it is possible to know at least the address and contact information, such as a phone number, and to easily and quickly take action such as confirming the fire.

[0028] (Effects of the device that controls the display of disaster prevention information) In addition, the specified device that controls the display of disaster prevention information includes a server, a mobile terminal, and a mobile phone terminal that are connected to the fire alarm system via a specified network.Therefore, by giving the necessary devices the function of a disaster prevention information display control unit and setting each device in the fire alarm system as a destination for fire occurrence information, map information can be used to inform external organizations and people involved in the fire of the fire situation, allowing them to quickly and easily understand the fire situation and take the necessary measures and decisions.

[0029] (Wide-area disaster prevention monitoring method) Another aspect of the present invention is a wide-area disaster prevention monitoring method for receiving and displaying fire information from a fire alarm system, wherein a disaster prevention information display control unit provided in a predetermined device connected to the fire alarm system via a predetermined network, when receiving fire information from the fire alarm system, displays a map including the facility where the fire alarm system is installed and identifiable displays the facility; when determining a selection operation for the facility where the fire occurred, displays the floor of the facility where the fire occurred and identifiable displays the floor on that floor; when determining a selection operation for the floor where the fire occurred, displays a floor map of the floor where the fire occurred and identifiable displays the section where the fire occurred on the floor map, thereby achieving the same effects as the wide-area disaster prevention monitoring system described above. Furthermore, the effects of other features of the wide-area disaster prevention monitoring method are also similar to the corresponding features of the wide-area disaster prevention monitoring system described above.

The contents will be explained separately as follows. a. Wide-area disaster prevention monitoring system b. Functional configuration of the receiver b1. Function b2.Fire monitoring control c. Server functional configuration d. Disaster prevention information display d1. Disaster prevention information display for buildings (large buildings, etc.) d2. Displaying disaster prevention information for homes e. Control operation of disaster prevention information display by the server f. Modifications 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 homes.

[0045] In the fire alarm system 1, for example, an R-type (Record type) receiver 10 is installed in a building manager's office or disaster prevention center, and signal lines 12-1, 12-n are drawn from the receiver 10 to the alert area for each system, and a plurality of analog fire detectors 14 with transmission functions and unique addresses set as terminal identification information are connected to 12-1 to monitor for fires. Also, an addressable transmitter 15 with transmission functions and unique addresses set is connected to signal line 12-1, and sends a fire notification signal when a push button is operated.

[0046] Smoke control devices 18 such as fire doors and smoke control dampers are connected to the signal line 12-n via repeaters 16 having transmission functions and set with unique addresses. In addition, gas leak detectors, gas shutoff valves, etc. are connected to the signal line via repeaters 16 having transmission functions and set with unique addresses, but are not shown in the figure. Note that the 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 provided with a gateway device 24, and when the receiver 10 determines that a fire has occurred, the gateway device 24 transmits fire occurrence information including a predetermined facility ID to a server 28 via the Internet 26.

[0048] The receiver 10 is also provided 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 provided with one or more wirelessly linked fire alarm devices 102, and when any of the fire alarm devices 102 detects a fire, it outputs a fire alarm and transmits a fire linkage signal to the other fire alarm devices 102 to output linked alarms. The residential fire alarm system 100 is also provided with an adapter 104 and a gateway device 24, and when the adapter 104 receives a fire linkage signal from any of the fire alarm devices 102, it converts the protocol and transmits fire occurrence information including the device ID from the gateway device 24 to a server 28 via the Internet 26.

[0050] When the server 28 receives fire information from the fire alarm system 1, it retrieves map information from the map information database 30 and displays on the screen a map including facilities such as the building where the fire occurred and the facility where the fire alarm system 1 that sent the fire information is installed, and places a specified fire mark on the building where the fire occurred on the map.When it determines that a selection operation is made by tapping on the fire mark placed on the building where the fire occurred, it displays a pop-up display of the floor of the building where the fire occurred and colors the floor on that floor where the fire occurred to identify it.When it determines that a selection operation is made by tapping on the fire mark placed in the fire area in the floor display, it displays a floor map of the floor where the fire occurred and places a specified fire mark in the fire area on the floor map.Furthermore, when it determines that a selection operation is made by tapping on the fire mark placed in the fire area, it performs control to display facility information such as the address and contact information of the building where the fire occurred.

[0051] In addition, the server 28 receives fire occurrence information from the residential fire alarm system 100, and when it identifies a residential fire from the system ID, it acquires map information from the map information database 30 and notifies the fire occurrence. A map including the house where the fire broke out and in which the residential fire alarm system 100 that sent the information is installed is displayed on the screen, and a fire mark is placed on the house where the fire broke out.If it is determined that a selection operation is performed by tapping on the fire mark placed on the house where the fire broke out, a hierarchical display is not performed, but a house floor plan that serves as a floor map of the house where the fire broke out is displayed, and a specified fire mark is placed in the fire section of the house floor plan.If it is determined that a selection operation is performed by tapping on the fire mark in the fire section, facility information such as the address and contact details of the house where the fire broke out is displayed.

[0052] In addition, a mobile phone terminal 34 is communicatively connected to server 28 via, for example, a mobile phone network 32, and further, a tablet terminal 38 or the like is communicatively connected to server 28 via a wide area wireless LAN communication network 36 such as a WiFi (registered trademark) communication network, making it possible to download screen information created by server 28's disaster prevention information display control and view it in the same way as server 28.

[0053] [b. Functional configuration of the receiver] (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, each of which is equipped with a sub-CPU 44 and a transmission unit 46. The main CPU 40 and the sub-CPU 44 are connected by an internal communication line 45, and transmit and receive data to and from each other.

[0054] The main CPU 40 is connected to a display 47 with a touch panel using an LCD 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 determination switch, a main sound stop switch, and a district sound pause switch, an acoustic alarm unit 52 equipped with a speaker, a reporting unit 54, and a transmission unit 55.

[0055] The main CPU 40 also has the function of a reception control unit 56 that is realized by executing a program.

[0056] (b2.Fire monitoring control) The sub-CPU 44 of the sub-CPU board 42 provided in the receiver 10 shown in Figure 2 performs fire monitoring 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 in accordance with a predetermined communication protocol.

[0057] During normal monitoring, the sub-CPU 44 performs fire monitoring control by periodically instructing the transmitter 46 to transmit a broadcast batch AD conversion signal containing a batch AD conversion command. Upon receiving this batch AD conversion signal, the fire detector 14 detects and stores the smoke density or temperature as sensor data. Subsequently, the sub-CPU 44 transmits a call signal containing a polling command that sequentially specifies the terminal addresses.

[0058] When the fire detector 14 receives a call signal having an address that matches its own address, it transmits a response signal including the sensor data it is holding at that time to the transmission unit 46 of the receiver 10. In addition, when the smoke density or temperature exceeds a predetermined fire warning 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 that includes the fire detector 14 that has detected the fire, and then sends an intra-group search command signal to identify the address of the fire detector 14 that has detected the fire, collects analog data from the sensors in a concentrated manner, and sends the data 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 determination level that is higher than the fire warning level, and when the analog data reaches the fire determination level, it determines that there is a fire, turns on the fire representative light on the display unit 48, outputs a predetermined acoustic alarm indicating a fire from the speaker of the acoustic alarm unit 52, 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 disaster prevention display device 20 is connected to the main CPU 40 via a transmission unit 55. The disaster prevention display device 20 has a function of displaying all events, including fire alarms, processed by the reception control unit 56 of the receiver 10 on a display 47, and in particular stores floor plans of the building that are to be alert areas, and when a fire is determined to have occurred by the receiver 10, it displays a floor plan of the floor on which the fire occurred based on the terminal address of the fire detector 14 that detected the fire, and also performs display control to display a detector symbol indicating the position of the fire detector 14 that detected the fire on the floor plan of the floor on which the fire occurred, for example by flashing red, as an alarm symbol.

[0062] For this reason, plan view position information indicating the coordinate position on the warning area plan view is registered in advance in the disaster prevention display device 20 in association with the terminal address of the fire detector 14.

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

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

[0065] Fig. 3 is an explanatory diagram showing the record format of equipment information. As shown in Fig. 3, equipment information 68 includes an equipment ID, location information, floor map information, facility information, contact information, etc. The equipment ID is identification information for distinguishing the fire alarm system 1 or the residential fire alarm system 100. The location information is the latitude and longitude that indicate the location of the fire alarm system 1 or the residential fire alarm system 100, and makes it possible to identify the location on a map.

[0066] The floor map information is a floor plan showing floor levels in a facility such as a building, and a residential floor plan showing the layout in a residence. The facility information includes the addresses and contact telephone numbers 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 is to be delivered.

[0067] Referring again to Figure 2, when the disaster prevention information display control unit 70 of the server 28 receives fire outbreak 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 memory unit 66, obtains a map of a predetermined scale including, for example, 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 outbreak mark on the map screen in the building where the fire occurred.

[0068] In addition, when the disaster prevention information display control unit 70 determines that a selection operation has been performed by tapping on the fire outbreak mark placed on the map in the building where the fire occurred, it controls the display of a pop-up display of the floor of the building where the fire occurred and the coloring of the floor where the fire occurred to identify it.

[0069] In addition, when the disaster prevention information display control unit 70 determines that a selection operation has been performed by tapping on a colored floor on the floor where the fire occurred, it displays a floor map of the floor where the fire occurred and also controls the placement of a predetermined fire occurrence mark in the fire occurrence section on the floor map.

[0070] Furthermore, when the disaster prevention information display control unit 70 determines that a selection operation has been performed by tapping on the fire outbreak mark on the floor map, it performs control to display the address, contact information, etc. as facility information of the building where the fire occurred.

[0071] On the other hand, when the disaster prevention information display control unit 70 of the server 28 receives fire information including the equipment ID and the terminal address based on the fire detection by the wireless-linked fire alarm 102 from the residential fire alarm system 100 shown in Figure 1, it obtains the equipment information of the residential fire alarm system 100 corresponding to the received equipment ID from the memory unit 66, obtains a map of a predetermined scale including the location of the house where the fire occurred from the map information database 30 based on the location information of the house where the fire occurred 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 map screen at the house where the fire occurred.

[0072] Furthermore, when the disaster prevention information display control unit 70 determines that a tap has been made to select the fire outbreak mark placed on the fire outbreak house displayed on the display, it controls to display a floor plan of the fire outbreak house without performing a hierarchical display and to place a predetermined fire outbreak mark in the fire outbreak section of the floor plan. Furthermore, when the disaster prevention information display control unit 70 determines that a tap has been made to select the fire outbreak mark on the floor plan, it controls to display the address, contact information, etc. as facility information of the fire outbreak house.
