SP6 is connected. When the emergency broadcasting device A receives a fire signal for each floor from the fire floor, it activates a tape reproducing device or a voice synthesizing device and automatically outputs a voice such as a fire occurrence guide to at least speakers on the fire floor and the floor immediately above. To do.
The automatic fire alarm is composed of a detector D and a receiver R, and the receiver R and the emergency broadcast device A are installed in a control room on a predetermined floor (first floor in the figure).

FIG. 7 shows a broadcasting floor which requires an alarm sound to be broadcast when a fire is stipulated by the Fire Service Law.
If a fire breaks out on the second floor or above, it is necessary to broadcast the fire information to the fire floor and the floor directly above. If a fire breaks out on the first floor, it is necessary to broadcast to the basement floor and the second basement in addition to the fire floor and the floor directly above it. It is also necessary to broadcast the fire information.

By the way, in recent years, skyscrapers have appeared. Since many people gather in such a skyscraper, appropriate evacuation guidance is needed from the viewpoint of securing human life in the event of a fire. Further, in recent skyscrapers, connected skyscrapers having a connecting portion on the middle floor or roof floor as shown in FIG. 8 have been constructed. Figure 8 (a) shows a building in which two buildings are connected on the middle floor and rooftop floor.

FIG. 5 is a diagram showing an emergency broadcast operation flow by the voice guidance device of FIG. 3 and the emergency broadcast device of FIG. 4 described above. In FIG. 5, the case where the voice guidance device 11 and the emergency broadcast device 13 operate in conjunction with each other will be described first. Here, interlocking refers to a state in which the automatic fire alarm detects a fire and outputs a floor-specific fire signal, so that the devices 11 and 13 operate in conjunction. At this time, when there is a floor-specific fire signal from the automatic fire alarm, the emergency broadcast device 13 controls the output control unit 23 to output the speaker on the fire floor and a predetermined floor (usually the floor directly above). At the same time, the operation control unit 22 is controlled to turn off the work input from the terminal t1,
The general business broadcast is stopped (steps S31 and S32). At this time, the voice guidance device 13 outputs a warning sound signal as the voice guidance voice signal L1 and enters the emergency broadcast device 13,
Broadcast to the output enabled speaker (step S3
3). Next, turn on / off the microphone switch SW0 (ON, O
FF) and whether the automatic / manual switch SW2 is on (automatic) or off (manual), the microphone switch SW0
If is turned off and the automatic mode is set, a fire occurrence guide signal is automatically broadcast from the voice guidance device 11 as the voice guidance voice signal L1 from the enabled speaker (steps S34 to S36). ). If the microphone switch SW0 is turned on in S34, broadcasting by the microphone in step S38 is performed.

Next, it is again determined whether or not the microphone switch SW0 is on (step S37). If it is on, broadcasting is performed by the microphone and then the process proceeds to the next step S39. If it is off, the next step S39 is performed. Move to. In S39, it is determined whether or not there is another fire signal, and if there is another floor-specific fire signal from the automatic fire alarm, the emergency broadcast device 13 causes the output control unit 23 to detect the floor of the fire signal. The speaker is controlled so that it can be output (step S40).
This is repeated until the next operation is performed (step S33).
~ Repeat S40).

Here, the fire condition by the person is investigated (step S41). Next, the operator selects broadcasting based on the survey result (step S42). That is, in S42,
Based on the result of the investigation, any one of the selection switches for the fire suppression broadcast, the false alarm broadcast, and the main fire broadcast arranged on the operation panel unit 12 of the voice guidance device 11 is turned on. S
In the case of a false alarm at 42, if the automatic fire alarm and emergency broadcast device are restored, the broadcast floor is selected, and the false alarm broadcast switch is turned on, the voice guidance device 11 can create and output a comment indicating that the false alarm has occurred. Broadcast from the selected speaker (steps S45, S46). In S42, in case of this fire,
It is determined whether or not the microphone switch SW0 is turned on (step S47), and if it is turned on, guided broadcasting by the microphone is performed (step S48). In S47, if the microphone switch is in the off state, the evacuation comment corresponding to the floor whose voice output is currently controlled is in the standby state, and the comment indicator 12b blinks to notify. Here, if the selected evacuation comment is broadcast, the operator turns on the blinking comment selection switch 12a to broadcast the evacuation comment to the floor controlled in step S40 ( Steps S49, S50).

If there is another floor requiring broadcasting, the operator manually operates the switch portion 14a of the emergency broadcast device 13 to manually select the floor requiring broadcasting (step S51). Again S47 ~ S52
Enter the step. If the microphone switch is off in S47, the output control unit 23 of the emergency broadcast device 13 needs to broadcast based on the floor fire signal from the fire floor and the floor selection signal from the newly selected floor input. The voice guidance device 11 simultaneously stands by for an appropriate evacuation comment and blinks the comment indicator lamp 12a. When the flashing comment selection switch is turned on, the evacuation comment will be broadcast. When the fire is extinguished and the fire is extinguished, the process proceeds to step S43. When the automatic fire alarm and the emergency broadcast device are restored, the broadcast floor is selected, and the fire suppression broadcast switch is turned on, the voice guidance device 11 creates a comment indicating that the fire has been extinguished, and broadcasts from the speaker capable of outputting (step S43). , S44).

Next, the voice guidance device 11 and the emergency broadcast device 1
A case where 3 is operated in a non-interlocked manner will be described. Here, non-interlocking refers to the case where a person on the fire floor or another building has notified of the occurrence of a fire without detection from the automatic fire alarm, and the automatic fire alarm outputs a floor-specific fire signal. Therefore, the state in which the devices 11 and 13 cannot operate in conjunction with each other is not possible. At this time, when a person confirms a fire (step S61), after manually turning on the emergency start switch SW1 of the emergency broadcast device 13, when the fire floor is selected by the switch section 14a, the relay contact R1 'is turned off. Then, the relay contacts R2 ', R3', R4 'are turned on. As a result, the general business broadcast is automatically stopped (step S6).
2). Further, when a predetermined floor is selected by the switch section 14a, the fire floor and the speakers on the predetermined floor are controlled so that they can be output, and the siren sound is output to these speakers (step S64). Next, if the microphone switch SW0 of the emergency broadcast device 13 is turned on, guided broadcasting by the microphone can be performed to the speaker on the selected floor (steps S47 and S48). A fire signal for each floor is input by inputting the fire floor using the ten-key pad of the operation panel unit 12 of the voice guidance device 11. An evacuation comment that can be broadcast from the floor-based fire signal and the floor currently being controlled is in a standby state, and the comment indicator lamp 12b blinks to notify. The operator is blinking the comment selection switch 1
By inputting 2a, the evacuation comment will be displayed in step S.
Broadcast to the floor controlled by 40 (steps S49, S
50). After that, it is similar to the case of interlocking.

The voice guidance device 11 and the emergency broadcast device 1
In the operation flow when 3 is operated in conjunction, the comment selection in step S49 is as follows depending on which floor is currently selected from the standby evacuation comments. Is prepared. That is,
When the speaker on the fire floor and the floor immediately above it are controlled to be able to output, for example, "it is a fire, it is a fire, please blame immediately." Also, the speaker on the floor above the fire floor and the floor immediately above is controlled. If there is a fire, for example, “A fire has just started on the ΔΔ floor of the XX building. Those above the ΔΔ floor should pass through the 40th floor and blame the building on the ground to the ground floor.” When the speakers on the fire floor and the floor below the floor immediately above are controlled, for example, a comment stating, "A fire has just broken out on the ΔΔ floor of the XX building. Please blame me for the fire." It

The comment selection in step S49 in the above flow is an operation for the operator to actually output the evacuation comment that has already been in the standby state. By omitting this step, it is possible to eliminate operator intervention. That is, when the evacuation comment is created by the operation of the voice guidance device 11 based on the floor fire signal and the floor selection signal, the evacuation comment may be automatically broadcast as it is without going through the standby state. , It is better to select manually to confirm that the comment contents are in the proper broadcasting situation.

When a fire occurs at two or more places and a plurality of fire signals for each floor are input, the blame route cannot be determined. Further, when a floor below the fire floor is selected, the speakers on the fire floor and the floor immediately above are controlled to be able to output while the fire signal is input. Therefore, comments blamed below will be evacuated toward the fire floor for people on the floor immediately above and cannot be broadcast because it is dangerous. For these reasons, in these cases, it is better to broadcast the comment "Please calm down and evacuate."

[0029]

As described above, according to the present invention, in a connected skyscraper, a broadcast showing an evacuation route is automatically created and broadcast to people on the fire floor and a predetermined floor. Therefore, appropriate evacuation guidance broadcasting can be performed even in the event of a fire.
