DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a self-fire alarm system which enables integrated alarm output.

[0002]

2. Description of the Related Art Conventionally, in apartment buildings such as condominiums (communal housing), an alarm monitoring panel is installed in a manager's office and the like, while a housing information panel (receiver for dwelling units) is installed in each dwelling unit. It is possible to make intercom calls with the housing information panel, alarm monitoring panel, and lobby intercom installed at the common entrance, and when a fire detector or gas leak alarm connected to the housing information panel issues a warning, Is notified to the alarm monitoring panel.

[0003] However, such a monitoring system has a main purpose of centrally monitoring each house information panel by an alarm monitoring panel. Therefore, in the event of a fire or the like, an entire apartment house, neighboring dwelling units, a lobby, a meeting place, Fire alarms were not automatically issued to common areas such as elevator halls, and evacuation guidance could not be provided. For this reason, instead of the alarm monitoring panel, a living room receiver (integrated panel) equipped with the function of this monitoring panel is installed in the manager's office, etc., and fire detectors installed in each dwelling unit and common areas are installed. When an alarm is issued, the receiver automatically notifies the housing information panel of a nearby dwelling unit or a bell in a common area of the occurrence of a fire, and performs integrated alarm monitoring throughout the apartment complex. It allows people to evacuate quickly.

[0004] In such a system, the house information panel is
When the fire detector issues an alarm, a first fire alarm is output by an alarm, a voice message, or the like, and the operation of the fire detector is notified to urge the dwellers to confirm whether or not a real fire has occurred. For example, a message such as "The fire detector has been activated. Please check" is output. Subsequently, if the switch for stopping the alarm is not operated within a predetermined time (for example, 5 minutes) from the time when the first fire alarm is output, a fire notification signal is output to the living room receiver. On the other hand, upon receiving the fire notification signal, the house ridge receiver sends an alarm control signal to a house information panel of a nearby dwelling unit which is set in advance as a notification destination. At this time, the target of sending the alarm control signal is
A house information panel of dwelling units located on the same floor as the house information panel that has output the fire alarm signal, a floor directly above, or the like, a receiver of a common use unit, a bell, and the like.

[0005] The housing information panel of a neighboring dwelling unit that has received an alarm control signal from the dwelling unit receiver outputs a second fire alarm to notify the occurrence of a real fire and to ask the dwellers to evacuate and take measures. For example, it outputs a message such as "Fire. Fire. A fire has occurred nearby. Please evacuate after confirming safety." FIG. 5 shows an example of the overall configuration of the self-fire alarm system described above.

Since the capacity for the number of signal lines is sufficient, the output and power supply capacity of the amplifier circuit unit 13 and the battery capacity can be reduced as compared with the related art. Since the necessity is eliminated, the standardization of the amplifier circuit unit 13 can be achieved.

When the housing ridge receiver 1 outputs the voice alarm, it simultaneously outputs an alarm control signal to the neighboring house information panel 2 via the transmission signal line L. Although not shown, the living building receiver 1 is configured with display means corresponding to each dwelling unit, a liquid crystal screen, display means including various display lights, various keys, switches, buttons, and the like. Operation means, internal alarm output means and the like are provided.

That is, upon receiving the fire notification signal, the living building receiver 1 displays the location of the fire on the display means and outputs an audio warning by the internal warning output means. An alarm control signal is also transmitted to a bell in a common area near the dwelling unit that has transmitted the fire notification signal via the transmission signal line L to activate the alarm control signal (see FIG. 5). FIG. 2 is a time chart showing an example of the above operation. Here, each of the blocks 1, 2, and 3 is a group (predetermined unit) of a plurality of house information panels 2 to which three audio signal lines L1 to L3 are connected, and each of these three blocks causes a fire. It shows a case where the unit is a group of dwelling units adjacent to the dwelling unit.

Therefore, in each block, a voice alarm message is output for each predetermined time t, and this output is cyclically repeated until an operation of stopping the alarm output in the living room receiver 1 is performed. Has become. Here, it is shown that the audio signal lines L1 to L3 for outputting the audio alarm are switched every predetermined time t, but the present invention is not limited to this, and is switched every predetermined number of voice phrases. You can also. For example,
The phrase "a fire broke out in a neighboring dwelling unit"
It is possible to sequentially output audio for each predetermined unit of neighboring dwelling units.

That is, in this case, when the information processing section 11 of the dwelling unit receiver 1 receives an alarm signal from the dwelling unit information panel 2 of any dwelling unit via the transmission signal line L, the information processing unit 11 of the dwelling unit adjacent to the dwelling unit The voice alarm output unit 12 is controlled so that the plurality of voice signal lines L1 to L3 connected to the house information panel 2 are sequentially switched every predetermined number of voice phrases. Also, the above-mentioned predetermined time t and the predetermined number of voice phrases are:
One of a plurality of stages can be selected or arbitrarily set in advance in the time / number setting unit 14. That is, the time / count setting unit 14 includes the information processing unit 1
The timing at which the audio alert output unit 12 switches the audio signal lines L1 to L3 can be set in advance. This setting is performed for the audio signal lines L1 to L3 to be switched.

Next, FIG. 3 shows the internal configuration of the house information panel 2 of each dwelling unit. The house information panel 2 includes an information processing unit 21 including a CPU, an audio alarm output unit 22 that controls an audio alarm output from the speaker SP, and an internal alarm storage unit 23 that stores a preset audio alarm message. And a transmission control unit 24 that performs transmission control via the transmission signal line L. Note that the information processing unit 21 retrieves a voice message from the internal warning storage unit 23 and causes the voice warning output unit 22 to output the internal warning message, thereby constituting an internal voice output unit of the present invention.

When the information processing section 21 of the house information panel 2 receives a voice alarm signal from the housing building receiver 1 through any of the voice signal lines L1 to L3, the voice message output section 22 directly receives the received voice message. While the output of this signal is stopped, a preset internal alarm is output. That is, while the housing ridge receiver 1 is outputting an audio alarm signal to the audio signal lines L1 to L3 connecting the other groups (blocks) of the house information panel 2, the house information panel 2 is set in advance. Outputs the internal alarm that has been performed.

In this internal alarm, since information on the neighboring dwelling unit where the fire has occurred is not known, a message such as "a fire has occurred in a neighboring dwelling unit" without information such as the fire floor or location (dwelling unit number). Is output. FIG. 4 is a time chart showing an example of the above operation. Here, as in the case of FIG.
Reference numeral 3 denotes a group of dwelling units adjacent to the dwelling unit in which the fire has occurred. In each block, a voice alarm message (external alarm) is output for a predetermined time t.

Therefore, the time (2t) during which the voice alert message is output in the other two blocks
Outputs an internal warning voice message. In this case, as in the case of FIG. 2, the external alarm may be switched every predetermined number of voice phrases. In this case, the internal alarm repeats the voice phrase until the next external alarm is output. do it.
