Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fire alarm system suitable for use in buildings equipped with a large number of fire detectors, such as buildings, inns, hotels, and department stores.

As we all know, traditional fire alarm systems usually
Fires are notified by bells and sirens. However, such notification means cannot notify the location of the fire, and the people inside the building cannot decide where to evacuate until an announcement is made. Additionally, such announcements are made by guards or employees who check the location of the ignition using centralized monitoring equipment installed in the guard room, so there is a drawback that it takes a considerable amount of time from the ignition to the announcement. It was hot.

On the other hand, with recent advances in speech synthesis technology, fire alarm systems have been proposed that detect the location of a fire, synthesize a corresponding message, and automatically make an announcement that also informs the location of the fire (for example, (Refer to Publication No. 161995/1983), such devices are generally complex and expensive, and the disadvantage is that the content of the announcement is not recorded and is not useful for after-the-fact investigations and confirmations, such as elucidating the cause of a fire. It was hot.
Additionally, broadcasting alone had the disadvantage that it was difficult to know which direction to evacuate to in large buildings or inns with winding corridors.

In view of the above circumstances, the present invention aims to realize a fire alarm device with a simple configuration that can automatically announce the location of the ignition, record the contents of the announcement, and display the evacuation direction. A plurality of fire alarms attached to the fire alarm, a determination circuit for determining which fire detector actually detected a fire among the fire detectors, and a plurality of messages corresponding to each fire occurrence location were sequentially recorded in the longitudinal direction. A first tape recorder having a magnetic tape, a second tape recorder having an endless magnetic tape, evacuation indicators installed in various parts of the building such as stairs, and broadcasting from the message group based on the output of the determination circuit. Select the message to be sent and
The magnetic tape is fast-forwarded to the recording position of the selected message to the second tape recorder, and a signal to play it is outputted, and the playback signal is recorded to the second tape recorder. and an evacuation direction selection circuit that selects an evacuation direction based on the output of the determination circuit and outputs a signal instructing the direction to be displayed on the evacuation display. The first announcement is made by directly outputting the message extracted from the first tape recorder, while the second and subsequent announcements are made by outputting the message stored in the second tape recorder in a short time. It is characterized by repeatedly taking out fires within the building, determining the evacuation direction depending on the location of the fire, and displaying the evacuation direction on evacuation indicators in various parts of the building.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention. In the figure, 1a, 1b...1n are fire detectors placed in various parts of the building (these are collectively referred to as fire detectors 1), which detect heat rays, convert them into electrical signals, and send these to the monitoring room. is supplied to the determination circuit 2 of The determination circuit 2 determines the location of the ignition by determining which fire detector has sent the signal, and supplies data D corresponding to this to the printer 3 and the message selection circuit 4. Here, the printer 3 has a clock, and prints and records the data D together with data such as date, hour, and minute.
The message selection circuit 4 also selects a group of messages recorded in advance in the recording device 5 (first voice storage/playback device) (for example, "A fire detector has been activated on the third floor. Evacuation near the ceiling"). Please evacuate by following the arrows on the display.'' This consists of at least a message created for each floor, and may also include messages instructing the evacuation direction and evacuation stairs.)
The message corresponding to the ignition location is selected from the following. This recording device 5 is composed of, for example, a cassette tape recorder, and the tape includes:
Message Mi (i) corresponding to each ignition location
=1, 2...) are stored one message at a time, separated by a predetermined space, as shown in FIG. Then, the message selection circuit 4 determines the number N of the message to be announced from the data D mentioned above, fast-forwards the recording device 5 while counting the spaces, and selects the message number N.
Extract M _N. Message extracted in this way
M _N is broadcast as the first announcement from speakers 7 placed at various locations via the broadcasting device 6, and at the same time is transferred to the recording device 5a (second audio storage and playback device) and recorded. Here, the recording device 5a has an endless tape that is short enough to record, for example, the longest message, and records the message M _N being broadcast onto this endless tape. After the first announcement is finished, the mode is switched to playback, and the second and subsequent announcements are the messages recorded on this endless tape.
M _N is broadcast repeatedly. In this case, since the endless tape is an extremely short tape capable of recording one message, the message M _N can be repeatedly broadcast within a short period of time.

Next, in Fig. 1, 8 is an evacuation direction selection circuit, and 9 is an evacuation direction selection circuit.
a, 9b...9m are evacuation indicators placed at high places on each floor (hereinafter, these evacuation indicators 9a~
When referring to any one or all of 9m, it is called evacuation indicator 9). Details of these are shown in FIGS. 3 and 4. That is, the evacuation indicator 9 has a left arrow and a right arrow, as shown in FIG. 3, and when a fire is detected, one of them blinks (flickers) to indicate the evacuation direction. Figure 4 shows an evacuation direction selection circuit 8 that flashes each of the arrows.
This shows the configuration of n fire detectors 1a, 1b...1n on the input side and m evacuation indicators 9.
It is composed of a diode matrix or the like with output sides a, 9b...9m, and for example, the left arrow of the evacuation indicator 9a blinks when any of the fire detectors 1a, 1b, or 1c detects a fire. When any of the other fire detectors 1d to 1n is activated, the right arrow blinks.
In this case, it is possible that both the left and right arrows flash at the same time, but in reality, it is rare for fire detectors located far apart in a large building to operate at the same time, and the above inconvenience is unlikely to occur. . Note that the above-mentioned components 2 to 6 and 8 are provided in a monitoring room where a guard or the like is present.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

Now, when one of the fire detectors, for example 1a, detects a fire, an electrical signal is sent to the determination circuit 2. The determination circuit 2 recognizes the firing location from this signal and supplies it as data D to the printer 3 and message selection circuit 4. The printer 3 automatically prints the time and the fire detector number based on the date, hour, and minute data supplied from the built-in clock and the data D. The message selection circuit 4 also determines the message number N corresponding to the data D, and also determines the message number I (this will be described later).
Initialize to 1 (step in Figure 5)
SP1). Then, in the next step SP2, the motor of the recording device 5 is started, and when the message number N is other than 1 (step SP3), the motor of the recording device 5 is started.
Message M _N with message number N is searched in SP4 to SP7. That is, in step SP4, the recording device 5 is set in fast forward mode, and each time a space between messages is detected (step SP5),
Add the value of message number I by 1 (step
SP6), finds a predetermined message M _N , switches the recording device 5 from fast forward to the playback state at the space in front of it (step SP8), puts the recording device 5a into the recording state, and starts recording the message M _N (Step SP8a). On the other hand, if the message number N is 1 in step SP3, the message _M1 is at the beginning of the tape, so the process immediately proceeds to steps SP8 and SP8a. In this way, when a message M _N to be announced is found, this message M _N is output from the recording device 5, and is broadcast from the speaker 7 via the broadcasting device 6 (step SP9).
M _N is recorded on the recording device 5a (step
SP9a). In this way, the first announcement is made by the output of the recording device 5. When the first announcement and the recording to the recording device 5a are completed at the same time (step SP10), the recording device 5 is rewound (step SP11) and enters the standby state (step SP12), while the recording device 5a enters the playback state. The message M _N recorded earlier is repeatedly broadcast (step SP11a). In this case, since the tape of the recording device 5a is an extremely short endless tape that can accommodate just one message, the message M _N is repeated within a short time, and the step SP13 is repeated.
It continues until it is stopped manually at , and when it is stopped, it goes into a standby state until the next fire is detected (step SP12), in preparation for the case of fire spread.

According to this embodiment, the recording device is duplicated, and while the message M N to be announced is extracted from a group of messages pre-recorded on the recording device 5 and broadcast, it is recorded on the recording device 5a, and the message M _N to be announced is broadcast. Since the second and subsequent announcements are made by this recording device 5a, it does not take much time to take out the message M _N from the second time onwards, and the announcements can be made continuously. That is, due to the duplication, from the second time onwards, the cue control of the message M _N and the time required for cueing become unnecessary, and the announcement can be repeated quickly and continuously.

Let's compare this with the case where there is only one recording device 5. In this case, if an ordinary cassette tape is used as the recording device 5, the tape will not be rewound and the message will not be sent when the second and subsequent announcements are made.
It is necessary to cue M _N , which makes control complex and takes time. Furthermore, when endless tape is used, it takes a long time to return to the desired message M _N because it contains a large number of messages. In contrast, in this example, the message
M _N can be announced repeatedly in a short period of time, making it suitable for emergency fire alarms.

Furthermore, in this embodiment, the broadcasted message M _N remains as a record in the recording device 5a, so it can be useful for follow-up investigations. In this respect, it is superior to devices that use conventional speech synthesis or devices that do not have dual recording devices.

Furthermore, since the evacuation display 9 indicates the direction of evacuation, it is possible to evacuate using both this instruction and the announcement as a guideline, making it possible to evacuate more quickly and safely.

Furthermore, this embodiment can be configured using an ordinary cassette tape recorder, and does not require complicated software unlike conventional speech synthesis devices that combine and broadcast words. , it has the advantages of being inexpensive and allowing messages to be easily added and changed. Another advantage is that emergency broadcasts can be made using human voices that are full of emotion.

Furthermore, since a record of the location of the ignition remains on the printer 3, this can also be useful for follow-up investigations.

Next, in a building with many floors, such as a high-rise building, the number of messages created corresponding to the location of the fire increases, so if these are recorded in multiple track format as shown in Figure 6, it will take less time to cue. can be shortened.

As explained above, the present invention includes a plurality of fire detectors installed at different locations, a determination circuit for determining which one of the fire detectors actually detected a fire, and a determination circuit corresponding to each location where a fire occurred. a first tape recorder having a magnetic tape on which a plurality of messages are sequentially recorded in the longitudinal direction; a second tape recorder having an endless magnetic tape;
A message to be broadcast is selected from the message group based on evacuation indicators installed in various parts of the building such as stairs and the output of the judgment circuit, and the message is sent to the first tape recorder to the recording position of the selected message. a message selection circuit that outputs a signal to fast-forward the magnetic tape and reproduce it, records the reproduction signal to a second tape recorder, and outputs a command signal to repeatedly reproduce the same after recording is completed; Since the configuration includes an evacuation direction selection circuit that selects an evacuation direction based on the output of the determination circuit and outputs a signal instructing the direction to be displayed on the evacuation display, the magnetic tape of the first tape recorder has a large number of evacuation directions. Messages can be recorded, and even in large or complex buildings, a sufficient number of messages can be stored for each anticipated ignition location using ordinary commercially available tape.

In addition, in combination with a second tape recorder having an endless magnetic tape, reproduction is quickly and repeatedly performed immediately after reproduction by the first tape recorder.

That is, according to the present invention, it is possible to select a message suitable for the situation from among a variety of message groups and quickly reproduce it repeatedly.

In addition, the endless tape records the broadcasted messages, and this record remains even if the power to the fire alarm device is cut off due to a power outage due to a fire, etc., so it can be useful for follow-up investigations.

Furthermore, since an evacuation indicator is provided to indicate the evacuation direction depending on the location of the fire, in combination with the above announcement, a quick and safe evacuation can be carried out.

Furthermore, since the location of the ignition is sequentially recorded on the printer, this information can be used for subsequent investigations such as investigating the cause of the fire.
