Description

[Detailed explanation of the invention] This invention is a broadcasting device installed in buildings such as buildings, especially
The present invention relates to a broadcasting device that can be used for emergency broadcasting.

Generally, large buildings such as buildings are equipped with broadcasting equipment for broadcasting business communications, business information, background music, and the like.

In the event of an emergency such as a fire, this broadcasting device is normally used for emergency broadcasting to notify the occurrence of an emergency situation and to provide evacuation guidance.

However, conventionally, in the event of an emergency such as a fire, the above-mentioned emergency broadcasts have not been sufficient for evacuation.

In other words, when evacuating, it is necessary for evacuees themselves to be aware of which floor they are on.
Even residents and employees of the pill may become upset and forget, or may become confused during evacuation.

This is especially true for foreigners who are unfamiliar with the pill.

Therefore, there was a problem in that evacuees became anxious and caused unnecessary confusion, and evacuation guidance could not be carried out smoothly.

This idea was made to solve this problem, and in an emergency, it allows evacuees to easily recognize which floor they are on, thereby reducing their anxiety and evacuation. An object of the present invention is to provide a broadcasting device that can smoothly provide guidance.

That is, this invention is a broadcasting system capable of broadcasting business communications etc. separately for each system through speakers distributed on each floor, and in which floor identification sound generating devices activated by the output of an emergency state detection device are provided for each floor. The output of the floor identification sound generator is connected via a changeover switch to a line leading to speakers installed on each floor of the building.

This invention will be explained below based on embodiments shown in the drawings.

FIG. 1 is a block diagram showing a basic embodiment of this invention.

The broadcasting device shown in the figure includes broadcast signal sources such as a microphone 1 and a background music generator 2, a mixer 3 that mixes these signals as appropriate, an amplifier 4 that amplifies the output, and an amplifier 4 that amplifies the amplified broadcast signal. Speakers on each floor 8□
... A broadcasting station 7 equipped with a system selection switcher 5 that selectively sends out all or part of 8n, and connected to the output terminals 6□...6n provided in the broadcasting station 7 corresponding to each floor. The outputs of the floor identification sound generators 91...9n, which are activated by the output of the emergency state detection device 10, are transmitted to a conventional broadcasting device consisting of speakers 81...8n, which are installed on each floor of the building. Selector switch 1 on the track leading to the speaker installed in
1□...11n.

The emergency state detection device 10 is, for example, a fire alarm, which issues an emergency signal when it detects a fire, and lights up an indicator light (not shown) based on its output.

The floor identification sound generating devices 9□...9n are activated by the emergency state detection device 10 and generate sounds that can identify which floor the floor is on, and are provided outside each floor.

For example, one that generates a pulse signal that repeatedly generates an intermittent sound corresponding to the number of floors, or one that generates a message that says, ``This is the fifth floor.

A magnetic recording/playback device is used to play back a tape on which content such as '' is recorded.

In addition, when using the intermittent tone as a floor identification tone, it is desirable to provide an appropriate reset circuit so that the intermittent tone is played from the beginning when the changeover switches 11□...11n are switched.

The changeover switches 11□...11n are switches for selecting between the broadcast signal and the signal from the floor identification sound generator, and when the switch is turned on at the contact point on the upper side of the drawing, the floor identification sound is output from the speaker 8□... 8n, and conversely, when the lower contact is turned on, emergency broadcasts and general broadcasts are broadcast.

Note that the switching of the changeover switches 11□...11n can also be linked with the system selection switch 5.

In this case, the switch operation becomes easy and confusion in the switch operation can be prevented in an emergency.

The microphone 1 can be used not only for normal business communication, but also for evacuation guidance in an emergency.

Note that the evacuation guidance procedure may be recorded in advance on a magnetic tape or the like, and this may be played back by a magnetic recording/playback device (not shown) to serve as a broadcast signal source.

The system selection switch 5 is a switch for selecting the floor on which to broadcast depending on the broadcast content, and the system selection switch 5 is a switch for selecting the floor on which to broadcast based on the broadcast content.
-Broadcasting signals can be selectively sent to speakers 8X on 8n or some floors.

A plurality of speakers 8□...8n are distributed and installed according to the structure of the building, and are connected to a speaker line for each floor.

The embodiment shown in FIG. 2 is a changeover switch control device 12□...12n that automatically switches the changeover switches 111...11n depending on the presence or absence of a broadcast signal in the broadcasting apparatus of the above embodiment. is added.

That is, this changeover switch control device 12□...12
When a broadcast signal appears from a broadcast signal source such as a microphone 1 to a speaker line on a selected floor via a □xer 3, an amplifier 4, and a system selection switch 5, it detects the broadcast signal and outputs the signal. For example, the selector switch 11K of the floor where the floor is located is switched from the output side of the floor identification tone generator 9X to the broadcast signal system where the system selection switch 5 is located.

On the other hand, selector switch 1 on another floor where no broadcast signal is detected
1 works to connect the speaker line to the output side of the 11th floor identification sound generator.

Therefore, in the event of an emergency, the floor identification sound generators 91, .
...The signal from 9n flows and the floor identification sound is broadcast.

On the other hand, for floors where general broadcasts, emergency broadcasts, etc. are being made, the changeover switch 11x is set to the broadcast signal system, so the general broadcasts, etc. are broadcast.

When operating the system selection switch 5 to make an emergency broadcast to all floors, the changeover switch control device 121...12n
detects the broadcast signal and all changeover switches 11
. . 11n are automatically switched to the broadcast signal system from the output side of the floor identification sound generators 9 .

Furthermore, if the broadcast signal is not output due to the interruption or termination of the emergency broadcast, the changeover switch control device 12□...12n causes the changeover switch 11□...11n to switch from the broadcast signal system to the floor identification sound generators 9, . . . 9n is automatically switched to the output side, and the floor identification sound is broadcast from the speakers 8□ . . . 8n on each floor without complicated switch operations.

In each of the above embodiments, each system of the system selection switch corresponds to each floor, but a plurality of systems may be provided on the same floor.

In this case, a changeover switch is provided for each system on the same floor, and the changeover switch connects all the outputs of the floor identification sound generators on the same floor to the speaker lines of each system on the same floor. , the configuration may be such that the changeover switches for each system on the same floor are linked.

The embodiment shown in FIG. 3 is an example in which this invention is applied to a broadcasting device in which an ara tenator is inserted in the speaker line.

The figure shows only the - code to simplify the explanation.

The broadcasting device shown in the figure has a system selection switch 5 equipped with a switch 5a for selecting a general broadcast system and a switch 5b for selecting an emergency broadcast system, an attenuator 13 inserted into the speaker line, and three sets of changeover switches. 11n is connected to a speaker line, and a floor identification sound generator 9n is connected via this.

In this embodiment, the upper contacts of the switches 5a and 5b are connected, and the output of the switch 5b is connected to the lower contact of the switch 5a.
If a is connected to the contact point on the upper side of the figure, the volume can be adjusted as appropriate using the attenuator 13.

On the other hand, if the switch 5b is connected to the contact point on the upper side of the drawing, a signal will flow in parallel to the fixed terminal of the attenuator 13 regardless of the connection state of the switch 5a, so that the attenuation of the signal by the attenuator 13 can be kept within a certain limit. can be broadcast at high volume.

Therefore, with respect to the floor identification sound generation device, it is possible to similarly limit the attenuation by the attenuator 13 to a certain limit and broadcast the floor identification sound at a high volume.

Moreover, by providing the changeover switch control device 12n,
It is possible to automatically switch between floor identification sounds and emergency announcements.

In each of the above embodiments, the changeover switch 11□...1
1n is provided inside the output terminals 6□...6n of the broadcasting station 7, but the changeover switch 111...11n is provided in the speaker line near the speakers 8□...8n. An example is shown in FIG.

In the figure, what is indicated by a dashed line A is a floor identification sound generator 9n and a changeover switch control device 1 in the speaker line.
This is an example in which a changeover switch 11n is provided together with 2n.

In this case, since the changeover switch 11n is located in the middle of the speaker line, the speaker 8n on the front side of the changeover switch 11n does not broadcast the floor identification sound because the floor identification sound generator 9n is not connected, and the speaker 8n on the rear side does not broadcast the floor identification sound. Only the speakers broadcast floor identification tones.

Furthermore, in the same figure, what is indicated by a dashed line B is an example in which a changeover switch 11 is connected to a line branched from a speaker line.

In this case, the floor identification tone is broadcast only from the speaker 81 connected to the branched line.

All of these methods are applied when it is desired to broadcast the floor identification sound only from a specific speaker due to the structure of the building.

As explained above, this invention, with the above configuration, can broadcast a floor identification sound in conjunction with the activation of the emergency state detection device in the event of an emergency, allowing evacuees to know which floor they are on. This has the effect of making it easier to recognize the situation, reducing feelings of anxiety, and facilitating evacuation guidance.

In particular, by automatically switching between floor identification sounds and emergency announcements, evacuation guidance can be performed more smoothly.
