Description

[Technical Field]

[0001] The present invention relates to a disaster prevention system that monitors fires by connecting a fire detector to a signal line drawn from a receiver. [Background technology]

[0002] Conventionally, disaster prevention equipment such as fire alarm systems that monitor fires by connecting fire detectors to signal lines drawn from receivers are known. Furthermore, conventional emergency broadcast systems are linked to disaster prevention equipment, and in the event of a fire, they notify the public of the occurrence of the fire and broadcast evacuation guidance.

[0003] The fire receiver installed in the disaster prevention equipment outputs a fire alarm when it receives an alarm signal from a fire detector that has detected a fire in a warning area and activated an alarm, and also transmits a floor-specific signal as an alarm area identification signal indicating the alarm area to the emergency broadcast device.The emergency broadcast device receives this and outputs a detector alarm broadcast from speakers installed on the floor where the fire occurred and on the floor directly above, saying, "The fire alarm on floor XX has just been activated.We are checking it, so please pay attention to the next broadcast."

[0004] When a predetermined time has passed since the detector was activated, or when a disaster prevention center staff member or other person goes to the scene and confirms a fire, the fire receiver sends a fire confirmation signal to the emergency broadcast device based on a fire confirmation operation, such as pressing a switch on the transmitter, and the previous detector alarm broadcast is switched to a fire broadcast, which outputs "Fire. Fire. A fire has broken out on the XX floor. Please remain calm and evacuate." Also, when a predetermined set time has passed since the fire broadcast, the emergency broadcast device switches to a simultaneous broadcast for the entire building.

[0005] On the other hand, if an emergency response officer goes to the scene and confirms that there is no fire, the emergency broadcast system will switch from the previous alarm broadcast to a non-fire broadcast by operating the non-fire broadcast switch, and will output the message, "We have checked the operation of the fire detector just now and found no abnormalities. Please rest assured." [Prior art documents] [Patent documents]

[Effects of the Invention]

[0025] (Basic effect) The present invention is a disaster prevention equipment equipped with a fire detector and a receiver, in which the receiver is provided with a reception control unit that performs a predetermined fire alarm process when a predetermined determination is made that a fire has occurred based on a predetermined fire information signal received from the fire detector, and a broadcast control unit that issues at least one of an audible fire alarm and a predetermined auxiliary broadcast from a broadcast alarm device when a predetermined determination is made that a fire has occurred.As a result, there is no need to install a dedicated emergency broadcast panel for broadcasts, especially emergency broadcasts, which reduces the installation space for the disaster prevention equipment and emergency broadcast equipment, and the fire display and fire origin floor display, etc., which are necessary for operating the emergency broadcast equipment, can be displayed on the receiver as is, eliminating the need for duplicate displays, and further, because disaster prevention personnel, etc. can operate the emergency broadcast on the receiver, they can quickly and appropriately operate and respond to emergency broadcasts in conjunction with fire response in an emergency such as a fire outbreak, ensuring high operability.

[0026] (Fire alarm screen and broadcast screen effects) In addition, the receiver is equipped with a display, and when the reception control unit makes a predetermined determination regarding the occurrence of a fire, it displays a fire alarm screen on part of the display indicating the occurrence of a fire and the location of the fire, and when the broadcast control unit makes a predetermined determination regarding the occurrence of a fire, it displays a broadcast screen for performing the operations necessary for broadcasting along with the fire alarm screen displayed on the display.Therefore, when a fire occurs, fire information such as the occurrence of the fire and the area where the fire occurred and the broadcast operation unit are displayed, for example, divided into upper and lower parts on a single screen, making it easy to perform operations such as setting the area where the emergency broadcast will be made and starting the broadcast.

[0027] (Broadcast area selection and the effect of simultaneous broadcasting) In addition, the broadcast screen is provided with a broadcast area selection section which selects the area to output the broadcast from when a predetermined determination is made regarding the occurrence of a fire, a broadcast instruction switch which commands the predetermined broadcast, and a general broadcast switch which commands a broadcast to all areas.When the broadcast control section receives operation of the broadcast instruction switch, it broadcasts to the area selected by the broadcast area selection section, and when it receives operation of the general broadcast switch, it broadcasts to all areas.As a result, emergency broadcast operations which were previously performed using switches located on the surface of the emergency broadcast panel can now be performed on the display screen provided on the receiver, and high operability is achieved by being able to display the switches necessary for operating emergency broadcasts on the screen along with their switch names.

[0028] (Effect of broadcast area selection section by list display) In addition, the broadcast area selection unit displays a list of area names and selection switch pairs on the broadcast screen, and the broadcast control unit detects the operation of the selection switch and selects the broadcast area.By displaying a list of area names and selection switch pairs that are the target of emergency broadcasts on the receiver's display, the operation of selecting the floor where the fire occurred and the floor immediately above it, which are displayed on the fire alarm screen, as the broadcast area can be performed easily and reliably.

[0029] (Effects of fire area indicator lights and broadcast area indicator lights) Furthermore, the broadcast area selection unit displays a list of pairs of area names and selection switches, along with fire origination area indicator lights and broadcast area indicator lights, and the broadcast control unit activates the corresponding fire origination area indicator light when a fire occurs, and activates the corresponding broadcast area indicator light when the selection switch is operated. Therefore, the floor where the fire occurred is designated as the broadcast area by operating the selection switch belonging to the pair of lit fire origination area indicator lights, and the floor immediately above the floor where the fire occurred can be easily and reliably selected as the broadcast area by operating the selection switch of the adjacent floor immediately above. Furthermore, during an emergency broadcast, the broadcast area indicator lights of the pair selected as the broadcast area are The light will turn on, making it easy to identify the floor on which the broadcast is being made.

[0031] (Effect of displaying broadcast content) In addition, the broadcast control unit displays the contents of the broadcast on the broadcast screen, so that the contents of the emergency broadcast currently being made can be easily confirmed by viewing them on the display.

[0032] (Effect of displaying the original text and translation of erroneous foreign broadcast content) Furthermore, when the broadcast is a foreign language broadcast, the broadcast control unit displays the contents of the foreign language broadcast in the original text on the broadcast screen as well as a translation of the foreign language broadcast. Therefore, when an emergency broadcast is being made in a foreign language, the original text and translation of the foreign language broadcast are displayed on the display, making it possible to simply and easily confirm the content of the emergency broadcast.

[0033] (Benefits of creating a broadcast scenario) In addition, the broadcast control unit generates and stores a broadcast scenario that sets areas to be broadcast in sequence in response to a fire occurring in a specified area using the operation unit of the broadcast screen, and displays the broadcast scenario on the broadcast screen when a fire occurs in the specified area.Therefore, when a fire occurs, a broadcast scenario that has been prepared in advance in response to the area where the fire occurred is displayed on the receiver's display, and broadcasts can be reliably made in the appropriate order to the area where the fire occurred and neighboring areas that are suited to the structure and situation of the building according to the displayed broadcast scenario.

[0034] (Effects of creating announcement scripts) In addition, the broadcast control unit generates and stores announcement scripts and script display conditions using the operation unit of the broadcast screen, and displays the announcement script on the broadcast screen when the script display conditions are met.Therefore, when a disaster prevention manager or the like uses an announcement microphone to make announcements such as evacuation guidance while watching the fire situation, a pre-prepared announcement script is displayed on the receiver's display, making it possible to make appropriate announcements according to the displayed announcement script even in the tense situation of a fire.

[0035] (Effect of repeat setting for announcement broadcast) Furthermore, when the operation unit on the broadcast screen is set to repeat announcements using the announcement microphone, the emergency broadcast control unit stores the announcement using the announcement microphone and then broadcasts it repeatedly. Therefore, when a disaster prevention manager or the like makes an announcement once, the repeat setting automatically repeats the announcement that was made once, ensuring that the content of the announcement is disseminated and reducing the burden on the disaster prevention manager or the like who makes the announcements.

[0036] (Effect of repeating announcement broadcasts with local audible warnings) In addition, when the operation unit on the broadcast screen is set to repeat announcement broadcasts using the announcement microphone and local acoustic alarms, the emergency broadcast control unit stores the announcement broadcast using the announcement microphone and then repeats the announcement broadcast with a local acoustic alarm in between.This means that, as necessary, announcement broadcasts are repeated with a local acoustic alarm in between, and the combination of disaster prevention equipment alarms and emergency broadcast equipment announcements can efficiently notify of fire outbreaks and provide evacuation guidance, etc.

[0037] (Effect of the fire alarm screen and broadcast panel operation unit) The receiver is also equipped with a display with a touch panel, and the reception control unit displays a fire alarm screen on the display in the event of a fire, indicating the occurrence of a fire and its location.A broadcast operation unit is provided on the receiver panel to perform the operations necessary for broadcasting, so that the display and operation of disaster prevention equipment is performed using the display screen and screen operation, and the display and operation of broadcasting equipment is performed using the hard switches and indicator lights on the receiver panel.This means that broadcasting can be operated using the hard switches on the receiver panel without changing the fire display and screen operation in the event of a fire on the receiver display.

[0039] [Disaster prevention equipment] FIG. 1 is an explanatory diagram showing an outline of an R-type disaster prevention system according to the present invention, in which the receiver is provided with the function of an emergency broadcast system.

[0040] (Basic Concept of the Embodiment) The disaster prevention equipment according to this embodiment is a disaster prevention equipment that monitors fires using analog fire detectors 14 connected to signal lines 12-1 and 12-2 drawn from a receiver 10. The receiver 10 is provided with a reception control unit 62 that performs predetermined fire alarm processing when a fire alert signal is received from the analog fire detectors 14, and an emergency broadcast control unit 64 that functions as a broadcast control unit that, when a fire occurs, issues a fire alarm and a predetermined auxiliary emergency broadcast for evacuation guidance from speakers 28 connected to broadcast signal lines 26-1 to 26-n drawn into the facility. Since there is no need to install a dedicated emergency broadcast panel separately, the installation space for the disaster prevention equipment and emergency broadcast equipment is reduced. Furthermore, the fire indication and fire floor indication required to operate the emergency broadcast equipment can be displayed on the display 42 of the receiver 10 as is, eliminating the need for duplicate displays. Furthermore, since disaster prevention personnel can operate the emergency broadcast on the receiver 10, they can quickly and appropriately operate and respond to emergency broadcasts in conjunction with fire response in an emergency such as a fire outbreak, ensuring high operability.

[0041] In particular, the receiver 10 is equipped with a display 42 with a touch panel, and when a fire breaks out, the reception control unit 62 displays a fire alarm screen on part of the display 42 indicating the occurrence and location of the fire, and the emergency broadcast control unit 64 displays an emergency broadcast screen for performing operations necessary for emergency broadcasting in the empty space of the fire alarm screen displayed on the display 42 when a fire breaks out, and when a fire breaks out, fire information such as the occurrence of the fire and the area where the fire has occurred and the emergency broadcast operation unit are displayed, for example, in separate upper and lower halves on the screen of the display 42, making it easy to confirm the area where the fire has occurred, set the area where the emergency broadcast will be made, and perform other operations such as making the broadcast. This will be explained in detail below.

[0042] (Outline of disaster prevention equipment) As shown in Fig. 1, an R-type receiver 10 is installed in a caretaker's room on the first floor of a building where disaster prevention equipment is installed, and signal lines 12-1 to 12-3 are drawn from the receiver 10 to the security area, separated for example into systems for each floor. In the following description, when there is no need to distinguish between the signal lines 12-1 to 12-3, they may be referred to as signal line 12.

[0043] A plurality of analog fire detectors 14 each having a transmission function and a unique address are connected to the signal line 12-1, and an on-off fire detector 18 and a transmitter 20 are connected to a detector line 17 drawn from a repeater 16 having a transmission function and a unique address.

[0044] In addition to the connection of multiple analog fire detectors 14, the signal line 12-2 is also connected to an addressable transmitter 22 with a transmission function and a unique address set thereto.Furthermore, the signal line 12-3 is connected to a smoke control and exhaust device 24 via a repeater 16 with a transmission function and a unique address set thereto.

[0045] Here, the maximum number of addresses that can be set for terminal devices such as analog fire detectors 14 and repeaters 16 connected to signal lines 12-1 to 12-3 is, for example, 255, and terminal devices including a maximum of 255 analog fire detectors 14 can be connected to signal line 12.

[0046] Furthermore, broadcasting lines 26-1 to 26-n are drawn out from the receiver 10 for the security area, for example, divided into systems for each floor, and broadcasting speakers 28 are connected to the broadcasting lines 26-1 to 26-n.

[0047] (Receiver functional configuration) The receiver 10 is provided with a main CPU 30 and a plurality of sub-CPU boards 32-1 to 32-3, and the sub-CPU boards 32-1 to 32-3 are provided with sub-CPUs 34-1 to 34-3 and transmission units 36-1 to 36-3.

[0048] The main CPU 30 and the sub CPUs 34-1 to 34-3 are connected by a serial transfer bus 40 and transmit and receive data to and from each other. In the following description, when there is no need to distinguish between the sub CPUs 34-1 to 34-3 and the transmission units 36-1 to 36-3, they may be referred to as the sub CPUs 34 and the transmission units 36.

[0049] A display 42 with a touch panel using a liquid crystal display panel or the like is connected to the main CPU 30, and the display 42 displays information necessary for fire monitoring by the receiver 10 according to the current status of the receiver 10. The information necessary for fire monitoring by the display 42 includes all information such as events that occur during normal monitoring and in the event of a fire, information necessary for operation and management, information necessary for response operations, and moreover information necessary for operation and management in the maintenance and inspection mode of the receiver.

[0050] In addition, the display 42 displays information necessary for operating emergency broadcasts in the event of a fire, and broadcast control and various settings can be made by operating the screen.

[0051] In addition to a display 42 that functions as a display unit for the main CPU 30, a display unit 44 using indicator lights such as LEDs is provided. The display unit 44 is provided with a fire indicator light, a gas leak indicator light, and the like.

[0052] An operation unit 46 is connected to the main CPU 30, and is provided with various switches required for fire monitoring, such as a fire determination switch, a main sound stop switch, and a district sound pause switch. Furthermore, an audio alarm unit 48 equipped with a speaker, and an alarm transfer unit 50 are connected to the main CPU 30.

[0053] The main CPU 30 is provided with a reception control unit 62 and an emergency broadcast control unit 64 that function by executing a program.

[0054] Furthermore, in order to realize the function of emergency broadcast equipment, the receiver 10 is provided with a broadcast sound source unit 52, an announcement microphone 54, an emergency broadcast speaker 56, a broadcast input selection unit 58, and a broadcast selection amplifier unit 60, the details of which will be explained later.

[0055] (Receiver appearance) 2 is an explanatory diagram showing the appearance of the receiver from the front. A display 42 with a touch panel using a liquid crystal display panel or the like is arranged on the face of the receiver 10. The display 42 displays color images on the screen, and the touch panel arranged on the screen allows selection and input by touching the screen. Note that the display 42 can be an appropriate image display panel such as an EL panel in addition to a liquid crystal display panel.

[0056] A guide switch 65 is located below the display 42 in the center of the panel from side to side, in a position that is easy for the user to see and operate. The guide switch 65 uses an illuminated switch with an illumination function, and the illuminated switch has a built-in indicator light such as an LED. When a fire event occurs and information that is the subject of guidance is displayed on the display 42, the illumination function of the guide switch 65 is activated and the switch flashes, prompting the user to operate the guide switch 65.

[0057] In addition, a fire determination switch 66, a main sound stop switch 68, and a local sound pause switch 70 are arranged on the panel below the display 42, enabling fire response operations in the event of a fire event. A small door 72 is provided on the panel below the guide switch 65 so that it can be freely opened forward with the lower side as an axis, and various operation switches including a recovery switch are provided on the inside of the small door 72.

[0058] A telephone microphone 78 is also located to the left of the fire decision switch 66, and in combination with a speaker inside a sound hole 77 provided next to the display 42, a hands-free emergency telephone function is realized.

[0059] In addition, a fire indicator light 75 and a gas leak indicator light 76 are provided on the upper panel of the display 42. Furthermore, a printer 74 is provided below the panel of the receiver 10, so that events that occur on the receiver 10 can be printed out.

[0060] In addition, since the receiver 10 is equipped with an emergency broadcast function, an announcement microphone 54 is placed on the panel below the small door 72 so that in the event of a fire, a disaster prevention manager or the like can use the announcement microphone 54 to make announcements for the fire alarm and evacuation. An acoustic hole 56a is provided on the panel below the announcement microphone 54, and the emergency broadcast speaker 56 shown in Figure 1 is placed inside it.

[0061] It should be noted that a telephone microphone may be used for broadcasting purposes instead of the announcement microphone 54. Also, instead of the sound hole 56a and the emergency broadcast speaker 56, the sound hole 77 and the speaker of the sound alarm unit 48 arranged inside it may be used for broadcasting purposes.

[0062] (Fire monitoring control of receiver) As shown in Figure 1, taking the sub-CPU 34-1 on the sub-CPU board 32-1 as an example, it performs fire monitoring control by instructing the transmitter 36-1 to send and receive signals to and from the analog fire detector 14 in accordance with a predetermined communication protocol. Downstream signals from the transmitter 36-1 to the analog fire detector 14 are transmitted in voltage mode. These voltage-mode signals are transmitted as voltage pulses that change the line voltage of the signal line 12-1 between, for example, 18 volts and 30 volts.

[0063] On the other hand, the upstream signal from the analog fire detector 14 to the transmitter 36-1 is transmitted in current mode. In this current mode, a signal current flows through the signal line 12-1 at the timing of bit 1 of the transmission data, and the upstream signal is transmitted to the receiver 10 as a so-called current pulse train.

[0064] During normal monitoring, the sub-CPU 34-1 fire monitoring control periodically instructs the transmitter 36-1 to transmit a broadcast batch AD conversion signal containing a batch AD conversion command. The analog fire detectors 14 that receive this batch AD conversion signal detect and store the smoke density or temperature as sensor data. The sub-CPU 34-1 then transmits a call signal containing a polling command that sequentially specifies the terminal addresses.

[0065] When the analog fire detector 14 receives a call signal with an address that matches its own address, it transmits a response signal that functions as a predetermined fire information signal and includes the sensor data it is holding at that time to the transmission unit 36-1. Also, when the smoke density or temperature exceeds a predetermined fire warning level, the analog fire detector 14 transmits a fire interrupt signal to the transmission unit 36-1 of the receiver 10.

[0066] When the sub-CPU 34-1 receives a fire interrupt signal via the transmission unit 36-1, it sends a group search command signal to identify the group that includes the analog fire detector 14 that has detected the fire, and then sends an intra-group search command signal to identify the address of the analog fire detector 14 that has detected the fire, collects analog data from the sensor in a concentrated manner, and sends it to the main CPU 30 via the serial transfer bus 40.

[0067] The main CPU 30 compares the analog data received from the sub-CPU 34-1 with a predetermined fire determination level, and when the analog data reaches the fire determination level, it determines that there is a fire, turns on the fire representative light 75 on the display unit 44, outputs a predetermined main acoustic alarm indicating a fire from the speaker of the acoustic alarm unit 48, displays fire alarm information including the location of the fire on the display 42 based on the address of the sensor where the fire was detected, and further outputs a fire alarm signal to the outside via the alarm transfer unit 50 to perform predetermined alarm transfer control, etc.

[0068] The fire monitoring control by the sub-CPU 34-2 and transmission unit 36-2 provided on the sub-CPU board 32-2 is the same as that of the sub-CPU board 32-1 described above. In addition, the sub-CPU 34-3 and transmission unit 36-3 provided on the sub-CPU board 32-3 perform interlocking control of the smoke control device 24 based on interlocking information stored in advance when a fire is detected by the main CPU 30.

[0069] [Emergency broadcast equipment] (Receiver emergency broadcast circuit section) Corresponding to the emergency broadcast control unit 64 provided in the main CPU 30 of the receiver 10 in Figure 1, the receiver 10 is provided with a broadcast sound source unit 52, an announcement microphone 54, an emergency broadcast speaker 56, a broadcast input selection unit 58, and a broadcast selection amplification unit 60.

[0070] The broadcast sound source unit 52 stores broadcast message information such as detector alarm broadcasts, fire broadcasts, non-fire broadcasts, emergency broadcasts for earthquakes, thefts, etc., and training broadcasts, and reads out the broadcast message information instructed by the emergency broadcast control unit 64, converts it into an analog broadcast signal, and outputs it.

[0071] The announcement microphone 54 is provided on the face of the receiver 10 as shown in FIG. 2, and allows a disaster prevention manager or the like to broadcast instructions such as evacuation guidance as necessary.

[0072] The broadcast input selection unit 58 connects the broadcast sound source unit 52 and the announcement microphone 54 as inputs, and selects one of the broadcast inputs in response to an instruction from the emergency broadcast control unit 64 and outputs it to the broadcast selection amplification unit 60.

[0073] The broadcast selection amplifier 60 outputs the broadcast signal input from the broadcast input selection unit 58 to a line selected from the broadcast lines 26-1 to 26-n in response to instructions from the emergency broadcast control unit 64, causing the signal to be broadcast from the speaker 28. The broadcast selection amplifier 60 is also provided with a power amplifier to enable the required speaker sound pressure output. A power amplifier may be provided for each speaker line, or a predetermined number of speaker lines may be grouped together and a power amplifier provided for each group.

[0074] (Normal monitoring screen) Figure 3 is an explanatory diagram showing the normal monitoring screen displayed on the receiver's display. As shown in Figure 3, when receiver 10 is in normal monitoring mode, normal monitoring screen 80 is displayed on display 42. Normal monitoring screen 80 displays a normal operation display 82 followed by menu buttons 84, 86, and 88, displaying menus for "Learn Procedures," "Operate," and "View Information." Touching any of menu buttons 84, 86, and 88 displays information or operation scenes corresponding to each menu. Furthermore, emergency broadcast menu button 89 is displayed on normal monitoring screen 80.

[0075] (Detector alarm broadcast setting screen) Figure 4 is an explanatory diagram showing the detector alarm broadcast setting screen. When the emergency broadcast menu button 89 is touched on the normal monitoring screen 80 in Figure 3, the emergency broadcast menu section 90 shown in Figure 4(A) opens, and when the detector alarm broadcast button 172 therein is touched, the detector alarm broadcast selection section 174 is displayed. Details of the manuscript creation button 138, scenario creation button 140, and various setting buttons 142 will be described later.

[0076] In the detector alarm broadcast selection unit 174 of Figure 4(A), for example, in this embodiment, if an eight-story building is the object of monitoring and emergency broadcasts are to be made separately for the southern and northern areas of each floor, the detector alarm broadcast floor selection lists 176-1 to 176-3 are arranged in 16 areas from the first floor south to the eighth floor north, which are the area names.

[0077] The detector alarm broadcast floor selection lists 176-1 to 176-3 are made up of the district name 116, a fire outbreak floor selection switch 180, and a broadcast floor selection switch 182, as shown in FIG. 4(B).

[0078] For example, as shown in the detector alarm broadcast floor selection list 176-1 in Figure 4(A), when the fire floor button for "1st floor south" is selected as the floor where the fire started, the broadcast floor selection switch is selected to broadcast "1st floor south" of the floor where the fire started, "1st floor north" which is the same as the floor where the fire started, or "2nd floor south" which is the floor directly above, and then when the setting button 178 is operated, "1st floor south," "1st floor north," and "2nd floor south" are set as the detector alarm broadcast floors corresponding to the fire floor "1st floor south," and when a fire alarm is received from the analog fire detector 14, a detector alarm broadcast is automatically made to the set broadcast floor.

[0079] (Detector alarm broadcast) Figure 5 is an explanatory diagram showing the fire monitoring screen immediately after a detector is activated and the emergency broadcast display screen for the detector activation broadcast, and Figure 6 is an explanatory diagram showing the fire monitoring screen and emergency broadcast screen when a fire occurs.

[0080] When a fire occurs and the reception control unit 62 of the receiver 10 determines that the detector should be activated based on a fire signal from the analog fire detector 14 shown in Figure 1, a fire alarm screen 92 shown in Figure 5 is displayed on the display 42.

[0081] Under the control of the reception control unit 62 in Figure 1, the fire alarm screen 92 displays a fire occurrence display 94 as well as a fire occurrence area display 96, and the fire occurrence area display 96 displays "Fire 1" indicating the first report, and the fire occurrence area as, for example, "Location 00-03-014-01, Building 1, 3rd floor, South 14 area, Time of occurrence 12:07:25."

[0082] In conjunction with this fire alarm display, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast selection amplifier unit 60 to select the broadcast output to the broadcast line for "3rd floor south," "3rd floor north," and "4th floor south" based on the detector alarm broadcast area and detector alarm broadcast content that have been preset in the area where the fire has occurred where the detector has been activated, and also instructs the broadcast input selection unit 58 to select the broadcast input from the broadcast sound source unit 52.In this state, it controls the broadcast sound source unit 52 to output the broadcast signal of the detector alarm broadcast stored in it, and as a result, a detector alarm broadcast stating, for example, "A fire alarm has just been activated in the 3rd floor south area.We are checking it, so please pay attention to the next broadcast," is output from the speakers 28 installed on "3rd floor south," "3rd floor north," and "4th floor south."

[0083] Furthermore, the monitoring screen 92 in Figure 5(A) displays an emergency broadcast screen 184, which displays a list of floors for detector alarm broadcasts 186-1 to 186-3, which, as shown in Figure 5(B), is composed of the district name 116, the fire origin floor indicator light 118, and the broadcast floor indicator light 120. As shown in the shaded area of ​​the detector alarm broadcast floor list 186-1, the fire origin floor indicator light for "3rd floor south" is lit, and the broadcast floor indicator lights for "3rd floor south," "3rd floor north," and "4th floor south" are also lit, making it possible to check the broadcast status of the detector alarm broadcasts.

[0084] (Fire broadcast) FIG. 7 is an explanatory diagram showing a broadcast floor selection screen in a list format, and FIG. 8 is an explanatory diagram showing a broadcast floor selection screen in a three-dimensional building diagram.

[0085] When the back button 115 in Figure 5 is pressed, the fire alarm screen 92 shown in Figure 6 displays a fire warning 94, and the disaster prevention manager checks the scene. If a fire is detected, the disaster prevention manager operates the fire determination switch 66 on the receiver 10 shown in Figure 2, which cancels the local sound alarm stop, performs interlocking control, and controls the transmission of the alarm.

[0086] In addition, when the disaster prevention manager touches the broadcast floor selection switch 100 in the emergency broadcast screen 98 displayed together with the fire alarm screen 92, the screen switches to the fire alarm screen 92 displaying the broadcast floor selection section 114 shown in Figure 7(A).

[0087] 7A, broadcast floor selection unit 114 has broadcast floor selection lists 114-1 to 114-3 arranged in 16 districts from 1st floor south to 8th floor north, similar to sensor alarm broadcast selection lists 176-1 to 176-3 in FIG.

[0088] As shown in FIG. 7B, the broadcast floor selection lists 114-1 to 114-3 are made up of a set of a district name 116, a fire outbreak floor indicator light 118, a broadcast floor indicator light 120, and a broadcast floor selection switch 122.

[0089] At this time, the display on fire occurrence area display unit 96 indicates "3rd floor south" as the area where the fire occurred, and the fire occurrence floor indicator light corresponding to the area name "3rd floor south" in broadcast floor selection list 114-1 turns red, for example, to indicate that it is lit, and based on this, the disaster prevention manager touches the broadcast floor selection switch corresponding to the area name "3rd floor south." When the broadcast floor selection switch for the area name "3rd floor south" is touched, the broadcast floor indicator light next to it turns blue, for example, to indicate that it is lit.

[0090] Additionally, since the disaster prevention manager needs to designate the "3rd floor south," the same floor as the fire outbreak, and the "4th floor south," the floor directly above, as broadcast areas, he touches the respective broadcast floor selection switches, causing the corresponding broadcast floor indicator lights to light up blue.

[0091] When such a broadcast floor selection operation is performed, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast selection amplifier unit 60 to select the broadcast output to the broadcast line for "3rd floor south," "3rd floor north," and "4th floor south" selected by the district broadcast selection unit 114, and also instructs the broadcast input selection unit 58 to select the broadcast input from the broadcast sound source unit 52.In this state, it controls the broadcast signal of the detector alarm broadcast stored in the broadcast sound source unit 52 to be output, and as a result, a fire broadcast stating, for example, "Fire. Fire. A fire has broken out in the 3rd floor south area. Please remain calm and evacuate." is output from the speakers 28 installed on "3rd floor south," "3rd floor north," and "4th floor south."

[0092] 8 shows another embodiment of the broadcast floor selection unit 114, which displays three-dimensional building diagrams 124-1 and 124-2 of the building to be broadcast. The three-dimensional building diagram 124-1 is a floor map of the first to fourth floors, and the three-dimensional building diagram 124-2 is a floor map of the fifth to eighth floors, and each floor map is divided into south and north, each of which constitutes a broadcast floor selection switch 126.

[0093] The broadcast floor selection switch 126 functions as either a fire floor indicator light or a broadcast floor indicator light, and when it operates as a fire floor indicator light, the display color is, for example, red, and when it operates as a broadcast floor indicator light, the display color is, for example, blue, and in the case of overlap, the red of the fire floor indicator light is displayed first. Alternatively, a red and blue stripe display may be used to indicate that the floor is both a fire floor and a broadcast floor.

[0094] At this time, the display on the fire occurrence area display unit 96 indicates "3rd floor south" as the area where the fire occurred, and since the floor map for 3rd floor south is red to indicate the floor where the fire started, the disaster prevention manager selects the floor where the fire started as the broadcast area by touching the broadcast floor selection switch for "3rd floor south," and then selects "3rd floor north," the same floor as the floor where the fire started, and "4th floor south," the floor directly above, as the broadcast area by touching the broadcast floor selection switch, and as a result, the display colors for "3rd floor north" and "4th floor south" turn blue to indicate that they are broadcast floors.

[0095] When such a broadcast floor selection operation is performed, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast sound source unit 52, the broadcast input selection unit 58, and the broadcast selection amplifier unit 60 to control the output of fire broadcasts from the speakers 28 installed on the "3rd floor south," "3rd floor north," and "4th floor south."

[0096] The broadcast floor selection unit 114 may also display the broadcast area of ​​the immediately preceding emergency broadcast. After a sensor alarm broadcast has been made, when selecting the broadcast area for a fire broadcast due to a fire being determined, the area where the sensor alarm broadcast was made may be automatically selected as the default broadcast area, or the broadcast area of ​​the immediately preceding emergency broadcast may be displayed separately from the broadcast area of ​​the next emergency broadcast.

[0097] The sensor alarm broadcast selection unit 174 shown in FIG. 4 may also be configured to select the floor to broadcast using the three-dimensional building diagrams 124-1 and 124-2 shown in FIG.

[0098] (Control of non-fire announcements and simultaneous announcements) In response to the fire alarm screen 92 shown in Figure 6 displaying a fire 94, the disaster prevention manager checks the site, and if there is no fire, he touches the non-fire broadcast switch 110 in the emergency broadcast screen 98 displayed together with the fire alarm screen 92. Based on this, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast sound source unit 52, the broadcast input selection unit 58, and the broadcast selection amplification unit 60 to output a non-fire broadcast, for example, "We have checked the operation of the fire detectors just now and found no abnormalities. Please rest assured." from the speakers 28 installed on the "3rd floor south," "3rd floor north," and "4th floor south."

[0099] Furthermore, if the fire spreads during a fire broadcast, for example, when the fire area display unit 96 displays the fire area due to a second fire alert, the disaster prevention manager touches the broadcast switch 112, and based on this, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast sound source unit 52, broadcast input selection unit 58, and broadcast selection amplification unit 60 to output the fire broadcast from the speakers 28 installed in all areas.

[0100] Also, when the fire is extinguished and the fire broadcast is no longer necessary, the disaster prevention manager touches the broadcast restoration switch 108, and based on this, the emergency broadcast control unit 64 in Figure 1 instructs the broadcast sound source unit 52, broadcast input selection unit 58, and broadcast selection amplification unit 60 to stop and restore the output of the broadcast signal.

[0101] The emergency start switch 102 is operated when the disaster prevention manager uses the announcement microphone 54 to manually make an emergency broadcast, or when switching from a detection alarm broadcast to a fire broadcast. In this case, there is no need to select the broadcast area as shown in Figure 7 or Figure 8, and a simultaneous broadcast is made to all areas. The emergency recovery switch 104 is operated to restore or stop the emergency broadcast or fire broadcast made by operating the emergency start switch 102.

[0102] (Display of broadcast content) Fig. 9 is an explanatory diagram showing an emergency broadcast screen that displays broadcast content. When a detector alarm broadcast is being made in conjunction with the occurrence of a fire, the emergency broadcast control unit 64 shown in Fig. 1 controls the display of a broadcast content display unit 128 on the fire alarm screen 92, as shown in Fig. 9(A). The broadcast content display unit 128 displays the message "We are currently in the south area on the third floor, please..." as the broadcast content 130-1, which is the content currently being broadcast. This allows the disaster prevention manager on the receiver 10 side to easily check the content of the emergency broadcast currently being made.

[0103] Figure 9(B) shows the case where the broadcast content display unit 128 displays the broadcast content 130-2 of the fire broadcast that follows the detector alarm broadcast based on on-site confirmation of a fire, and Figure 9(C) shows the case where the broadcast content display unit 128 displays the broadcast content 130-3 of the non-fire broadcast that is made when on-site confirmation reveals no fire.In the same way, disaster prevention managers and the like can easily check the broadcast content that is currently being made.

[0104] Figure 10 is an explanatory diagram showing an emergency broadcast screen that displays the contents of emergency broadcasts in foreign languages. In recent years, the number of facilities used by foreigners has increased, and emergency broadcasts may be made in foreign languages ​​other than Japanese, such as English, Chinese, and Korean.

[0105] When a foreign language broadcast is also made as an emergency broadcast, the emergency broadcast control unit 64 provided in the receiver 10 of Figure 1 controls the broadcast content display unit 128 of the fire alarm screen 92 to display the content of the fire broadcast currently being broadcast, for example in English, in English in the foreign language broadcast content 132, and also to display a translation of the foreign language broadcast (English broadcast) in the translated broadcast content 134, as shown in Figure 10.

[0106] As a result, when an emergency broadcast is being made in a foreign language, the original text and translation of the foreign language broadcast are displayed on the display 42, so that a disaster prevention manager or the like on the receiver 10 side can simply and easily confirm the content of the emergency broadcast.

[0107] The above broadcast content may be displayed on the same screen as the display content showing the location of the fire and the broadcast location, as represented by the detector alarm broadcast floor list 186-1 to 186-3, or may be switched and displayed by operation.

[0108] [Emergency broadcast support function] (Emergency broadcast script creation function) Figure 11 is an explanatory diagram showing an emergency broadcast screen for creating and setting a script for an emergency announcement broadcast. As shown in Figure 11, an emergency broadcast menu section 90 on the normal monitoring screen 80 displayed on the display 42 is provided with a sensor alarm broadcast button 172, a script creation button 138, a scenario creation button 140, and various setting buttons 142, which function as an emergency broadcast support section. Figure 11 shows the case where the script creation button 138 is touched, and an emergency broadcast script creation section 144 is displayed below the emergency broadcast menu section 90.

[0109] The emergency broadcast script creation section 144 is provided with an announcement number 146, a broadcast message 148, announcement conditions 150, a save button 152, an English keyboard 154, and a numeric keypad 156.

[0110] The emergency broadcast script creation unit 144 is controlled by the emergency broadcast control unit 64 provided in the receiver 10 of FIG. 1, and the disaster prevention manager or the like can use the announcement microphone 54 to make a notification when a fire occurs in a specific location. A script for an emergency announcement is created by inputting Roman letters on the English keyboard 154 and numbers on the numeric keypad 156, as shown in a broadcast message 148, for example, "Fire! Fire! A fire has broken out in the machine room on the first floor. Those on the first floor should evacuate calmly from the south side emergency exit, and those on the second floor should evacuate from the emergency stairs on the second floor."

[0111] Furthermore, as the announcement condition 150, the location of the fire is set to "Fire, 1st floor, machine room" in accordance with the content of the manuscript 148. When the save button 152 is touched in this state, the emergency broadcast control unit 64 stores in memory the information consisting of the announcement number "001" generated in the emergency broadcast manuscript creation unit 144, the content of the manuscript 148, and "Fire, 1st floor, machine room" set as the announcement condition 150.

[0112] When a fire breaks out, the emergency broadcast control unit 64 determines that the location of the fire is "1st floor machine room," and automatically displays the stored broadcast script in the emergency broadcast screen area of ​​the display 42. A disaster prevention manager or the like can make an emergency announcement using the announcement microphone 54 while watching the displayed broadcast script.

[0113] This allows disaster prevention managers, etc., to make appropriate emergency announcements in accordance with the displayed announcement script, even in the tense situation of a fire, by having a prepared announcement script displayed on the display 42 of the receiver 10 when a fire occurs, which has been set as announcement condition 150.

[0114] (Emergency broadcast scenario creation function) Fig. 12 is an explanatory diagram of an emergency broadcast for creating and setting an emergency broadcast scenario. When the scenario creation button 140 in the emergency broadcast menu section 90 shown in Fig. 11 is touched, an emergency broadcast scenario creation section 158 is displayed below the emergency broadcast menu section 90.

[0115] The emergency broadcast scenario creation unit 158 ​​is provided with a scenario number 160, a broadcast scenario 162, a scenario condition 164, a save button 152, an English keyboard 154, and a numeric keypad 156.

[0116] The emergency broadcast scenario creation unit 158 ​​is controlled by the emergency broadcast control unit 64 provided in the receiver 10 of Figure 1, and a disaster prevention manager or the like creates a broadcast scenario in the event of a fire breaking out at a specific location by entering roman characters on the English keyboard 154 and numbers on the numeric keypad 156, as shown in items 1 to 4 of the broadcast scenario 162, for example, "Fire determined in the south area on the 6th floor," "Emergency broadcast to the 6th and 7th floors," "Emergency broadcast to the south area on all floors," and "Emergency broadcast to the entire building."

[0117] Furthermore, as the scenario condition 164, "Fire breaks out, 6th floor, south area" is set in accordance with the content of the broadcast scenario 162. When the save button 152 is touched in this state, the emergency broadcast control unit 64 stores in memory the information consisting of the scenario number "001" generated by the emergency broadcast scenario creation unit 158, the content of the broadcast scenario 162, and "Fire breaks out, 6th floor, south area" set as the scenario condition 164.

[0118] When a fire breaks out, the emergency broadcast control unit 64 determines that the fire has occurred in the "sixth floor, south area," and automatically displays the stored broadcast scenario in the emergency broadcast screen area of ​​the display 42. Therefore, when a fire breaks out, a broadcast scenario prepared in advance corresponding to the area where the fire has occurred is displayed on the receiver's display 42, allowing the disaster prevention manager or the like to make emergency broadcasts in the appropriate order according to the displayed broadcast scenario.

[0119] (Announcement broadcast repeat setting) 13 is an explanatory diagram showing an emergency broadcast screen for setting the repetition of emergency broadcast announcements. When various setting buttons 142 in the emergency broadcast menu section 90 shown in FIG. 13 are touched, an announcement broadcast setting section 165 is displayed below the emergency broadcast menu section 90.

[0120] The announcement broadcast setting section 165 is provided with an announcement broadcast repeat setting section 166 and a local sound alarm sandwich setting section 168, each of which is provided with an ON button and an OFF button.

[0121] The announcement broadcast is made by the disaster prevention manager using the announcement microphone 54 and can only be broadcast once, but in this embodiment, an announcement broadcast that has been made once can be stored and can be repeated as needed.

[0122] If it is desired to repeat the announcement broadcast, an operation mode for repeating the announcement broadcast is set by touching the ON button of the announcement broadcast repeat setting unit 166. As a result, when a disaster prevention manager or the like makes an announcement broadcast using the announcement microphone 54, the emergency broadcast control unit 64 can store this announcement broadcast and then broadcast it repeatedly at a predetermined interval, ensuring that the announcement broadcast can be heard reliably.

[0123] In addition, when an emergency broadcast including an announcement broadcast is made, the local sound alarm is stopped, but by touching the ON button of the local sound sandwich setting unit 168, an operation mode is set in which the announcement broadcast using the announcement microphone 54 is stored and then the announcement broadcast is repeated with the local sound alarm sandwiched between.

[0124] As a result, when a disaster prevention manager or the like makes an announcement using the announcement microphone 54, the emergency broadcast control unit 64 can store this announcement and then repeatedly output the announcement and the local acoustic alarm at a predetermined interval, and by combining the alarm from the disaster prevention equipment and the emergency broadcast from the emergency broadcast equipment, it is possible to efficiently notify people of a fire outbreak and give instructions for evacuation guidance, etc.

[0125] [Embodiment in which an emergency broadcast operation unit is provided on the receiver panel] In the above embodiment, as shown in Figure 2, an emergency broadcast screen is displayed on the display 42 provided on the receiver 10, and the operations and various settings required for the emergency broadcast are performed.However, in another embodiment, an emergency broadcast operation unit equipped with hard switches and indicator lights for performing the operations required for the emergency broadcast is provided on the panel of the receiver 10 shown in Figure 2.

[0126] The emergency broadcast operation section provided on the receiver panel includes the setting switch 178, fire origination floor selection switch 180, broadcast floor selection switch 182 shown in the detector alarm broadcast selection section 174 of Figure 4, hardware switches corresponding to the emergency start switch 102, emergency recovery switch 104, fire broadcast switch 106, broadcast recovery switch 108, non-fire broadcast switch 110 and general broadcast switch 112 shown in the emergency broadcast screen 98 of Figure 6, and indicator lights and hard switches corresponding to the district name 116, fire origination floor indicator light 118, broadcast floor indicator light 120 and broadcast floor selection switch 122 in the broadcast floor selection list 114-1 to 114-3 shown in the broadcast floor selection section 114 of Figure 7.

[0127] In this way, when an emergency broadcast operation section using a hard switch is provided on the receiver panel, emergency broadcasts can be operated and set using the hard switch provided on the receiver panel without changing the fire display and screen operation on the display 42 of the receiver 10 in the event of a fire.

[0128] [Modifications of the present invention] (Emergency broadcast equipment) In this embodiment, the receiver may be configured to allow the user to listen to the contents currently being broadcast, for example, by outputting the broadcast contents as audio from the audio port 56a.

[0129] Furthermore, the broadcast contents may be stored in the speakers 28, and when a broadcast is to be made in the event of a fire or the like, the receiver may issue a command to each speaker to instruct the speaker to broadcast the contents.

[0130] The receiver may also be capable of checking the status of each terminal, such as smoke control equipment, so that the status of the terminal can be checked even when an emergency broadcast is made.

[0131] The emergency broadcast scenario may also be configured to report the location of the currently relevant item number depending on the progression of the fire, the operation status of the reception control unit and the emergency broadcast control unit, etc. For example, in Figure 10, item number 1 is highlighted along with the scenario display when a detector is activated, item number 2-1 is highlighted when a fire is determined due to detector activation in multiple locations or a fire determination operation on the receiver, item number 3 is highlighted when an emergency broadcast such as a fire broadcast is made including the 6th and 7th floors, and item number 4 is highlighted when an emergency broadcast is made to the south area of ​​all floors. In order to report the location of the currently relevant item number depending on the progression of the fire and the operation status of the reception control unit and the emergency broadcast control unit, etc., transition conditions for each item number are set as scenario conditions when the emergency broadcast scenario is created.

[0132] (Broadcast Control Unit) In the above embodiment, the broadcast control unit is the emergency broadcast control unit 64, but it may be configured to broadcast general broadcasts other than emergency broadcasts.

[0133] (wireless sensor) The above embodiment takes as an example a communication form in which the fire detector 14 is connected to a signal line drawn from the receiver 10 to the security area of ​​the facility, but the fire detector 14 may be a wireless fire detector, and some or all of the communication between the receiver and the fire detector may be wireless.

[0134] (Fire information signal) In the above embodiment, the response signal including the sensor data of the analog fire detector is used as the predetermined fire information signal, but the predetermined fire information signal may also be a response signal from a repeater or a fire detection signal from an on-off fire detector.

[0135] (input device) The input device is not limited to a touch panel, but may be a mouse, a keyboard, or other suitable input device, or may be a voice input device.

[0136] (P-type receiver) The above embodiment takes as an example a disaster prevention equipment in which an R-type fire detector is connected via a signal line from an R-type receiver, but similarly, for disaster prevention equipment in which an addressable fire detector with a transmission function is connected and an address is set on the detector line drawn from a P-type receiver, by displaying a fire alarm screen and an emergency broadcast screen on the display on the receiver panel in the event of a fire, there is no need to install a dedicated emergency broadcast panel separately, reducing the installation space for the disaster prevention equipment and emergency broadcast equipment, and by using the fire indication and fire origin floor indication, etc., which are necessary for operating the emergency broadcast equipment, as they are displayed on the receiver's display, there is no need for duplicate displays, and furthermore, since disaster prevention personnel can operate the emergency broadcast on the receiver, they can quickly and appropriately operate and respond to emergency broadcasts in conjunction with fire response in the event of an emergency such as a fire, ensuring high operability.

[0137] (Automatic broadcast function) In addition, in the above embodiment, the emergency broadcast control unit selects the broadcast area by operating the screen when a fire occurs based on an analog fire detector and makes a detector alarm broadcast, but it may also be configured to automatically select the floor where the fire occurred and the floor immediately above based on the fire area and make a detector alarm broadcast. Furthermore, if the emergency broadcast control unit confirms the fire on site during a detector alarm broadcast and makes an emergency broadcast, it may switch to a general broadcast after a predetermined time has passed.

[0138] (others) Furthermore, the present invention includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited to the numerical values ​​shown in the above embodiments. [Explanation of symbols]
