Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency alarm device,
More specifically, the present invention relates to an emergency alarm device that gives an alarm by voice to respond to the occurrence of an abnormal situation such as a fire.

[0002]

2. Description of the Related Art Conventionally, an emergency alarm device, for example, a fire alarm device, has been used in general homes and buildings, and when a fire is detected by a flame detector, a smoke detector, a heat detector, etc., it rings a bell. Moreover, the occurrence of a fire is notified by turning on a display or the like.

In particular, in a building with a plurality of floors, the building is divided into floors, blocks, and buildings, and each division is divided into
By providing a repeater unit connected to the central fire alarm receiver and connecting a plurality of flame detectors to this repeater unit, a fire is detected for each section. Then, when the occurrence of a fire is detected in a specific section, the fire alarm receiver controls each repeater according to the location and the situation of the fire, and the configuration of the building. An alarm is issued by ringing all the bells connected to each repeater all at once, or ringing only the bell connected to the repeaters on the upper floor.

[0004]

However, in such a conventional emergency alarm device, a bell is sounded to notify only the occurrence of a fire, and the fire situation, that is, where the fire occurs. It is not possible to obtain information such as whether a fire has occurred or how much fire it is. Furthermore, what kind of criticism action should be taken against the fire that is occurring is the best. I can't get the information.

In this way, the notification of the fire only by the bell is
Due to the small amount of information, it was not possible to take appropriate criticisms, which could lead to unnecessary confusion.

[0006] Therefore, conventionally, an emergency alarm device has been proposed which generates an alarm by voice in addition to the alarm by ringing a bell. In this case, an alarm by voice is
Even in a building, etc., the same sound information, for example, "a fire broke out on the 3rd floor" is only generated via all the repeater units, and the bell is rung to trigger the fire. There is no great difference in the amount of information compared with the case of notification, and there is a problem that it is not possible to notify the detailed fire situation and appropriate criticism.

Therefore, an object of the present invention is to provide an emergency alarm device capable of giving more detailed and appropriate information.

[0008]

An emergency alarm device according to the present invention includes a plurality of detectors for detecting an emergency, a plurality of alarms for alerting an emergency, and at least the detector and the alarm. A plurality of relays to which alarm devices are connected, and a control unit that detects the occurrence of an emergency based on a detection signal from the detectors, drives the alarm devices via the relays, and generates an alarm. An emergency alarm device comprising:
Each of the relays includes a voice data storage unit that stores a plurality of voice data of appropriate alarm content in the relay, and the control unit detects the occurrence of an emergency from a detection signal from each of the detectors. , For each of the repeaters, at least one of the voice data stored in the voice data storage means is designated together with the signal designating the repeater, and an instruction to generate an alarm is issued. According to an instruction from the control unit, the designated voice data is read from the voice data storage means, and a voice alarm is generated via the alarm device, thereby achieving the above object.

The emergency alarm device of the present invention is, for example,
As described in claim 2, the control unit outputs to the repeaters, together with a signal designating the repeaters, a signal for rewriting the contents of the audio data storage means and the rewriting voice data, and each of the relays. However, the above object is achieved by rewriting the content of the audio data in the audio data storage means in response to an instruction from the control unit.

[0010]

According to the emergency alarm device of the present invention, each repeater is
In the voice data storage means, a plurality of voice data of appropriate alarm contents are respectively stored in the relays, and when the control unit detects the occurrence of the emergency from the detection signals from the detectors, Along with the signal designating the repeaters, at least one of the voice data stored in the voice data storage means is designated to issue an alarm, and each repeater responds to the instruction from the control unit. Then, the designated voice data is read from the voice data storage means, and a voice alarm is generated through the alarm device. Therefore, for each relay device, the situation in which each relay device is installed or the fire occurrence condition is detected. Appropriate audio data can be selected to generate an audio alert. As a result, a more appropriate and information-rich alarm can be issued.

Further, since the control unit can specify the repeater for each repeater and rewrite the contents of the voice data stored in the voice data storage means, it is necessary to visit each repeater one by one. However, the content of the voice data of each repeater can be appropriately rewritten according to the installation status of each repeater, and the alarm content can be made simple and more appropriate.

The fire alarm device 1 of the present embodiment, like a normal fire alarm, judges whether or not a fire has occurred based on the detection signals from the relay unit C1 to Cn, and determines that a fire has occurred. If judged, a fire warning is given.

However, in the fire alarm device 1 of the present embodiment, the alarm for the occurrence of the fire is given by voice for each district unit T1 to Tn, which is appropriate for the situation where the district unit T1 to Tn is installed. It has its characteristics.

Hereinafter, this alarm processing is performed by the fire alarm receiver 2 and the voice alarm controller 3, and each relay unit C
The processing in 1 to Cn will be described separately.

First, the processing in the fire alarm receiver 2 and the voice alarm controller 3 will be described with reference to the flowchart shown in FIG.

The fire alarm receiver 2 includes the repeater units C1 to C1.
A transmission signal is transmitted to and received from Cn, and it is checked whether or not the transmission signal received from each of the repeater units C1 to Cn includes a signal indicating the occurrence of fire (step S1).

The fire alarm receiver 2 includes relay units C1 to C1.
When the transmission signal from Cn includes a transmission signal indicating the occurrence of fire, the transmission signal recognizes that the fire has occurred (step S2), analyzes the situation of the fire from the signal content indicating the fire, The analysis result is output to the voice alarm controller 3 as detection information (step S3).

The voice alarm controller 3 is the fire alarm receiver 2
A voice alarm corresponding to the fire situation is selected for each repeater unit C1 to Cn based on the detection information from (step S4), and each selected repeater unit C1 to Cn is selected.
A voice information identifier corresponding to each voice alarm is generated, and the voice information identifier and the relay identifier are output for each of the relay units C1 to Cn (step S5).

Next, the processing in each of the repeater units C1 to Cn will be described based on the flowchart shown in FIG.

Each of the repeater units C1 to Cn determines whether or not a transmission signal is sent from the voice alarm controller 3.
Always check (step Q1), and when a transmission signal is sent, the repeater identifier is extracted from the transmission signal, and whether the repeater identifier in the transmission signal matches the repeater identifier assigned to itself. Check whether (step Q2).

That is, each of the repeater units C1 to Cn
Is a repeater identification decoder 2 that determines the repeater identifier in the transmission signal.
It is decoded in step 3 and it is checked whether the decoded repeater identifier matches its own repeater identifier.

In step Q2, when the repeater identifier in the transfer signal does not match the repeater identifier assigned to itself, the process returns to step Q1 and similar processing is performed.
When they match, it is checked whether the command signal in the transmission signal is a restoration command or a rewriting command (step Q).

In step Q3, when the command signal is the restoration command, the voice information identifier is decoded by the voice information identification decoder 22, the voice data corresponding to the decoded voice information identifier is extracted from the voice data ROM 25, and the voice restoration processing is performed. The data is output to the unit 26 (step Q4). The voice restoration processing unit 26 restores the extracted voice data, and the amplifier 2
The signal is amplified by 7 and output in a loud voice from the speaker B1 (step Q5).

That is, each of the repeater units C1 to Cn
When there is a transmission signal and the repeater identifier of the transmission signal matches its own repeater identifier, it checks whether the command signal is a restore command, and when it is a restore command, it corresponds to the voice information identifier of the transmit signal. The voice data is read from the voice data ROM 25, the contents of the voice data are restored, and then the voice output is performed.

As described above, the voice data ROM 25 can store voice data having different contents for each of the repeater units C1 to Cn, and the voice alarm controller 3 can store the voice data depending on the occurrence state of the abnormality. Each repeater unit C1
The audio data suitable for Cn is designated by the audio information identifier.

As the contents of this voice data, for example,
As a combination of information on location and fire, "A fire broke out on this floor. Please evacuate according to ○○ immediately.""A fire broke on the □□ floor. Evacuate immediately according to ○○ "A fire broke out near here. Please evacuate immediately according to ○○.""A fire broke out near □□. Please evacuate immediately according to ○○.""This There was a fire on the lower floor. Please evacuate immediately according to ○○. "" A fire broke out in the □□ room. Please evacuate immediately according to ○○. " As a combination of information on smoke and smoke, "The passages ahead are full of smoke and dangerous. Please bypass.""This stair is full of smoke and dangerous. Please. "" No smoke in this room Is dangerous. Please do not enter. ”“ The room is full of smoke and dangerous. Please do not enter. ”“ This passage is full of smoke. It is dangerous. Please do not enter. ”“ This staircase is full of smoke and it is dangerous. Please do not enter. ”

Further, as the information contents of the evacuation route, there are "Please use this stairs to evacuate." "Use this passage to evacuate."

As the information content of the malfunction, "the fire on this floor was a malfunction." "The fire on the □□ floor was a malfunction." "The fire near this was a malfunction. "The fire near □□ was a malfunction." "The fire on the lower floor was a malfunction." "The fire in the □□ room was a malfunction."

It should be noted that the above-mentioned □□ and □ ○ mean the words of the contents changed according to the installation situation of each district unit T1 to Tn.

Therefore, each of the repeater units C1 to Cn
Of the repeater units C1 to Cn by appropriately selecting the sound data stored in the sound data ROM 25 of
It is possible to give a sound alert to the floor, ridge, or block where the building is installed with appropriate content, and encourage appropriate evacuation behavior.

Further, the voice data in the voice data ROM 25 may be appropriately combined and selected, and the voices may be output in the order of selection. By doing so, a more appropriate alarm can be issued. At the same time, the capacity of the audio data ROM 25 can be reduced.

When the command signal of the transmission signal is the rewriting command in step Q3, the voice data in the voice data ROM 25 is rewritten by the voice data included in the transmission signal (step Q6).

That is, without going to the place where all the repeater units C1 to Cn are installed, the repeater units C1 to Cn from the voice alarm controller 3 are not visited.
Of the voice data of the voice data ROM 25 of the above, depending on the installed state of each relay unit C1 to Cn,
It can be written or rewritten as appropriate, and the contents of the audio data can be easily and easily made into more appropriate contents.

In the example of the voice data, the alarm at the time of fire occurrence and the malfunction thereof are shown, but it goes without saying that it is not limited to this. For example, when the fire is extinguished, voice data for notifying the recovery may also be stored in the voice data ROM 25 for notification.

In the above embodiment, the case where the present invention is applied to the fire alarm device 1 has been described, but the present invention is not limited to this and can be applied to, for example, an earthquake alarm device.

Further, in the above embodiment, both the detectors P1 to Pn and the speakers B1 to Bn which are alarm devices are connected to the repeater units C1 to Cn, but the present invention is not limited to this. The devices P1 to Pn are speakers B1 to
Bn may be connected to a different repeater, or may be directly connected to the fire alarm receiver 2 without going through the repeater. In short, the speaker B1 which is an alarm device connected to each of the repeater units C1 to Cn stores appropriate sound data for each of the repeater units C1 to Cn, and gives an audio alarm according to the occurrence state of the abnormality. What is necessary is that it can be generated through ~ Bn.

[0068]

According to the present invention, a voice alarm can be generated for each repeater by selecting voice data suitable for the condition where each repeater is installed and the fire occurrence condition. It is possible to make more appropriate and information-rich alerts.

Further, since the contents of the voice data stored in the voice data storage means of each repeater can be rewritten, the contents of the voice data of each repeater can be changed without going to each repeater. The alarm content can be easily rewritten according to the installation situation of the container, etc., and
The content can be more appropriate.
