Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mutual monitoring system in which a group is composed of a plurality of dwelling units connected via a CATV line, and each dwelling unit in the group mutually monitors for an abnormality such as a fire.

[0002]

2. Description of the Related Art In recent years, there has been an increasing awareness of regional crime prevention and regional disaster prevention, in which one's life and property are protected by oneself, and various forms of crime prevention and disaster prevention are being implemented in each region.
As one of these, a mutual monitoring system called a group monitor system is known. In this mutual monitoring system, neighboring dwelling units gather to form a group, and a CA
An alarm receiver that connects a group monitor device and a fire detector that are interconnected using a TV line will be installed.

When an emergency such as a fire, a gas leak, or an emergency occurs in any of the dwelling units in the group, an alarm is issued to the dwelling unit by an alarm receiver, and at the same time, the occurrence of the emergency is notified to the other dwelling units by the group monitor device. You. The group monitor of the other dwelling units that have received the notification of the occurrence of the emergency will indicate the fire, gas leak, emergency, etc. by the type display, and simultaneously turn on the dwelling unit lights to display the dwelling unit where the abnormality has occurred, and also sound the alarm by voice synthesis. And alert by voice message.

[0004] Therefore, in the event of an emergency in the group, neighboring dwelling units can quickly and accurately cope with the situation, and the initial fire extinguishing can be performed quickly.

[0005]

However, in such a conventional mutual monitoring system, when an alarm receiver installed in a dwelling unit receives, for example, an alarm from a fire detector, it is immediately sent to another dwelling unit. Since a fire was reported and an alarm was issued, if the fire detector caused an alarm due to a malfunction, there was a problem that all other dwelling units in the group would be notified of the fire even though there was no fire. .

[0006] Therefore, after confirming the non-fire and restoring the alarm receiver, it is necessary to go to another dwelling unit where the alarm has been issued or contact by telephone or the like to notify that there is no abnormality. In other words, there was a risk that measures to be taken in the event of a false report would be complicated. Further, if false reports occur frequently, the reliability of the mutual monitoring system will be greatly impaired, and it may not be possible to properly respond to an emergency such as a fire.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and reduces troubles caused by erroneous detection of abnormalities, and enhances reliability by alarming reliable abnormality detection in other dwelling units. The purpose is to provide a mutual monitoring system.

[0008]

In order to achieve this object, the present invention is configured as follows. First, the present invention relates to CATV
A group is composed of multiple dwelling units connected via a track, and each dwelling unit in the group receives an alarm from a detector due to detection of an abnormality such as a fire, and issues an alarm with an alarm receiver and an alarm receiver A group monitor is provided to send the received abnormal information to another dwelling unit via the CATV line to make an alarm, decode the abnormal information received from the other dwelling unit and issue an alarm, and provide an alarm between each dwelling unit in the group. It targets a mutual monitoring system that monitors each other.

According to the present invention, in the case of such a mutual monitoring system, when the abnormality received and notified by the alarm receiver is undetermined, the group monitoring device transmits the abnormality undetermined information to another dwelling unit. The warning notification section that notifies the warning warning by the
An abnormality confirmation notification unit that sends abnormality confirmation information to other dwelling units to notify an abnormality alarm, and when a recovery operation is performed after an alarm is issued by an alarm receiver, sends restoration information to another dwelling unit to warn a warning or abnormality. A recovery notification unit that recovers and stops the alarm and an alarm cancellation notification unit that sends alarm cancellation information to other dwelling units based on the operation of the cancellation switch to stop the alarm output and notify that there is no abnormality are provided. It is characterized by having.

Here, when the alarm receiver is monitoring the alarm reception of at least one heat detector line connecting the plurality of smoke detector lines connected to the smoke detector and the heat detector, the warning notification unit is provided. When an alarm receiver receives a notification of one of the smoke detector lines, after a lapse of a predetermined time, transmits abnormal unconfirmed information to another dwelling unit to notify a fire warning. In addition, the abnormality confirmation notification unit is configured to: when the alarm receiver receives the alarm of two lines of the smoke detector line; when it receives the alarm of one line of the heat detector line; when the fire confirmation switch is operated; In any case, it is determined that the fire has been determined, and the abnormality determination information is transmitted to the other dwelling units to notify a fire abnormality alarm.

[0011] Therefore, even if the smoke detector circuit receives an alarm due to cigarettes or smoke from cooking, in this case, the fire is undecided and a warning is issued at another dwelling unit to prepare for the confirmation of the fire. it can. If the fire was not confirmed by the on-site confirmation, the alarm was stopped by the recovery operation and the cancel switch was operated to notify that there was no abnormality in the other dwelling units. There is no trouble like an alarm.

If a fire is confirmed at the site, the occurrence of a fire can be immediately alerted by operating a fire determination switch.
Also, assuming a case where the fire determination switch cannot be pressed due to an initial fire extinguishing or the like, the fire can be reliably notified and alarmed by the automatic fire determination by receiving the second report of the smoke detector line. Furthermore, as for the alarm reception of the heat sensor line, since there is almost no possibility of non-fire, in this case, the fire is determined immediately and a fire alarm is notified in another dwelling unit.

[0013] When the group monitor apparatus receives the alarm cancellation information, if an alarm has been issued for a plurality of dwelling units, the alarm cancellation is not notified, and the alarm for the dwelling units in the alarm state is continuously performed. For example, when an alarm is displayed on the group monitor device for an abnormality of two dwelling units, even if a cancellation operation is performed on one of the dwelling units, the other one dwelling unit is still in an abnormal state, and the notification of the cancellation and the notification of the alarm are issued. Mixed and confusing.
In order to avoid this confusion, the alarm is terminated without notifying the canceling dwelling unit of the cancellation, and the alarming of the other dwelling units is continuously performed to prevent confusion.

The group monitor has a voice synthesizing unit for outputting a voice alarm message by voice synthesis, and the voice synthesizing unit outputs abnormal unconfirmed information, abnormal confirmed information, or abnormal cancellation information from another dwelling unit. The corresponding predetermined alarm sound and voice alarm message are output. In this case, 2
In order to appropriately discriminate the occurrence of abnormalities in and above the dwelling unit and issue an alarm, the unit lights indicating the abnormal dwelling unit are flashed during the output of the audio alarm by the voice synthesis unit, and the dwelling unit lights are switched to the lighting state when the output of the audio alarm is completed.

Upon receiving the data, an analog voice signal is generated by voice synthesis, and an alarm sound and a voice message are output from the speaker 48.

FIG. 3 is a flow chart of the transmission processing in the group monitor device of FIGS. 1 and 2 when the alarm is emitted from the sensor and various switches are operated in the dwelling unit. First, in step S1, the monitor unit 14 captures the states of the transfer lines AL1 to AL5 of the alarm receiver 10, the fire determination switch 50, and the cancel switch 52. And step S
In step 2, it is checked whether or not the fire determination switch 50 of the switch unit 16 operated by confirming the fire spot has been turned on. If the fire determination switch 50 has been turned on, the process proceeds to step S3, where the abnormality determination notification unit 64 of the monitor processing unit 60 shown in FIG. 2 reports fire determination information to other dwelling units, and returns to step S1.

If it is determined in step S2 that the fire determination switch 50 has not been turned on, the process proceeds to step S4, in which a cancel switch 52 for canceling an abnormality determination report, a warning report, or the like based on the alarms of the heat sensor 26 and the smoke sensor 28 is issued. Check whether or not is turned on. When it is determined that the cancel switch 52 is turned on, the process proceeds to step S5, where the alarm cancellation notification unit 68 of the monitor processing unit 60 shown in FIG. 2 reports alarm cancellation information to other dwelling units.

If the cancel switch 52 has not been turned on in step S4, it is checked in step S6 whether or not the heat detector 26 has issued an alarm. If the alarm from the heat detector 26 is determined, the process proceeds to step S7, and the abnormality confirmation reporting unit 64 reports fire confirmation information to other dwelling units. If the alarm is not issued from the heat sensor 26 in step S6, it is checked in step S8 whether the alarm is issued from the smoke sensor 28. If the alarm from the smoke detector 28 is determined, it is checked in step S10 whether the alarm from the smoke detector 28 is a two-line alarm, that is, whether the second alarm is received. If it is determined that there is, the process proceeds to step S16, and fire determination information is reported to other dwelling units.

If the smoke detector 28 is not the two-line alert but the first alert, the process proceeds to step S11. If the timer has not started, the timer is started in step S12. If the timer is already counting in step S11, or if the timer has been started in step S12, the process proceeds to step S13, and it is determined whether a predetermined time (for example, two minutes) has elapsed since the timer was started.

After a lapse of a predetermined time, that is, the smoke detector 28
If two minutes have passed since the first line was issued, step S14
Then, the caution notification unit 62 of the monitor processing unit 60 of FIG. 2 operates to transmit the fire undecided information to the other dwelling units to perform the caution notification. If the predetermined time has not elapsed since the start of the timer in step S13, the process proceeds to step S15,
Notify other dwelling units that there is no abnormality.

If it is determined in step S8 that the smoke detector 28 has not issued an alarm, the process proceeds to step S9. If the timer has already been started, the timer is stopped. In step S15, another dwell unit is notified of no abnormality. , And returns to step S1 again. Note that, in this step S8, the state in which the timer is started despite the fact that the smoke detector 28 has not issued the alarm means that once the smoke detector 28 has issued the alarm and started the timer, an alarm is issued. This is a case where the recovery switch 34 of the receiver 10 is operated. The notification of the absence of abnormality due to the recovery in step S15 is performed by reporting the recovery information to the other dwelling unit by the recovery notification unit 66 provided in the monitor processing unit 60 in FIG.
The recovery information at this time may be information indicating that there is no abnormality in the normal monitoring state, or a signal dedicated to the recovery information.

FIG. 4 is a flowchart of the reception processing of the group monitor apparatus for the fire unconfirmed information (caution information), the fire confirmation information, the recovery information, and the alarm cancellation information transmitted by the group monitor transmission processing of FIG. Here, for the sake of simplicity, a case will be described as an example where a notification is received from dwelling unit 1B at dwelling unit 1A in FIG. First, step S
When it is determined in step 1 that the caution message has been received based on the fire undetermined information, the process proceeds to step S2, in which the fire lamp 36 flashes on the monitor unit 14 of the dwelling unit 1A in FIG. 1 and the dwelling unit light 42B indicating the dwelling unit 1B in which the abnormality has occurred. Flashes. Further, the voice synthesizing unit 76 issues a cautionary warning from the speaker 48 stating "Woooo detector fire may be caused."

Next, when a decision report based on the fire decision information is received in step S3, the process proceeds to step S4, in which the decision lamp 38 of the monitor unit 14 of the dwelling unit 1A blinks, and the dwelling unit light 42B of the dwelling unit 1B in which the abnormality has occurred blinks. . Also, at this time, if the warning sound A of the caution warning in step S2 or the warning sound C of the cancellation notification in step S8, which will be described later, is output, this is stopped and the warning sound B for fire confirmation is output as ""Woooo, fire! Please come to help."

If a recovery notice based on the recovery information is received in step S5, the process proceeds to step S6, in which the fire light 36 or the decision light 38 and the dwelling light 42B of the monitor unit 14 which were blinking in step S2 or step S4 are turned off. Then, the sound output of the warning sound A of the caution warning output in step S2 or the fire determination warning sound B output in step S4 is stopped.

Further, if the cancellation notification based on the alarm cancellation information is received in step S7, the process proceeds to step S8. If the fire light 36 or the confirmation light 38 is blinking, it is turned off and the lighting 40 is blinked. Further, if the warning sound A for the caution warning in step S2 or the warning sound B due to the fire determination in step S4 has been output, this sound output is stopped. Then, as a warning sound C for canceling the warning, a sound output of "ping-pong, the current warning is incorrect" is output. The lighting 40 goes out after 3 minutes.

Further, at the time of the caution alarm of step S2 and the fire alarm of step S4 in FIG. 4, the dwelling unit light of the dwelling unit where the abnormality has occurred is blinking. In order to clarify the correspondence with the dwelling unit light, the corresponding dwelling lamp is flashed while the alarm sound A or the alarm sound B is being output, and when the sound output is stopped, the dwelling unit light is switched on. Therefore it immediately recognize whether the voice alert is being carried out of how dwelling unit.

When the fire unconfirmed information and the fire definitive information are received at the same time, an alarm may be given by giving priority to the processing for the fire definitive information. In other words, when the monitor unit 14 of the dwelling unit 1A receives the fire unconfirmed information from the dwelling unit 1B and receives the fire definitive information from the dwelling unit 1C, the monitoring unit 14 gives priority to the fire determination information received from the dwelling unit 1C, The decision lamp 38 and the dwelling lamp 42C of the dwelling unit 1C are turned on and off, and an alarm sound B for fire confirmation is output. In addition, dwelling unit 1B
In order to be able to recognize that the fire undetermined information has been received from, the fire lamp 36 is turned on, and the dwelling lamp 42B of the dwelling unit 1B is turned on, and an alarm is issued only by display.

FIG. 5 is a flowchart of another embodiment of the receiving process when the alarm cancellation information is received in step S7 of FIG. In the cancellation notification receiving process of FIG. 5, when the alarm is canceled in two or more dwelling units in the group when the alarm cancellation information is received from another dwelling unit, the alarm sound of the cancellation of the alarm is not output. It is characterized by having done. For example, FIG.
In the monitor unit 14 of the dwelling unit 1A, the fire lamp 3 is displayed by the notification display based on the fire occurrence of both the dwelling units 1B and 1C.
6 and the dwelling unit lights 42B and 42C are blinking. In this state, when the cancellation information is reported by, for example, turning on the cancel switch 52 following the recovery of the alarm receiver of the dwelling unit 1B, the dwelling lamp 42B of the dwelling unit 1B is turned off, and the alarm sound C is output as the alarm sound C in step S8 in FIG. "Ping-pong The current alarm is incorrect" is output.

However, at this time, the recovery of the alarm receiver and the operation of the cancel switch 52 in the dwelling unit 1C are not performed, so that the fire lamp 36 of the monitor unit 14 is not turned off, and the dwelling unit lamp 42B is turned off. Also dwelling unit light 42 of dwelling unit 1C
C is blinking. For this reason, the dwelling unit lamp 42C indicating the abnormality in the dwelling unit 1C is flashing despite the audio output of “ping-pong, the current alarm is incorrect”, and the audio output indicating that there is no abnormality is output. Contradict.

Therefore, in the cancellation notification receiving process of FIG. 5, the alarm sound of the alarm cancellation is output only when there is no abnormality in which all the dwelling units other than the one which sent the alarm cancellation information are not in the alarm state. I have. That is, if the warning cancellation information is received, it is checked in step S8 whether or not a warning is currently issued for dwelling units other than the dwelling unit that sent the warning cancellation information.
And terminates the alarm for the canceled dwelling unit without outputting the sound of the alarm cancellation. That is, processing similar to the recovery processing in step S6 of FIG. 4 is performed. Then, the alarm processing of the remaining dwelling units in the alarm state is continuously performed.

On the other hand, in step S8, if only the alarm for the dwelling unit that sent the alarm cancellation information is currently being issued, no alarm is issued for the other dwelling units.
0, if the fire light 36 and the confirmation light 38 shown in step S8 of FIG.
Flashes. Further, the sound output of the warning sound C accompanying the warning cancellation is performed.

In the above embodiment, one heat sensor 26 is connected to the five sensor lines L1 to L5 from the alarm receiver 10.
The case where four smoke detectors 28 are connected is taken as an example,
Whether to connect the heat detector 26 or the smoke detector 28 can be appropriately determined according to the situation of the dwelling unit to be installed. In the above embodiment, the fire monitoring in which the heat detector 26 and the smoke detector 28 are connected to the alarm receiver 10 is taken as an example. However, a gas leak detector or an emergency detector may be connected. The alarm monitor 10 receives a notification signal from a gas leak detector or a notification signal from an emergency detector to the group monitor device 12A, and sends a gas leak report or emergency report to the other dwelling units 1B to 1H. In addition, the lighting of the gas leak indicator lamp and the emergency indicator lamp further provided in the display unit 72 and the speaker 48
Can output a corresponding voice message.

As an alarm sound due to a gas leak, for example, "pop-po-gas leak has occurred" is output, and for an emergency, "pe-po-p-po emergency has occurred" is output.

Practically, it is desirable to have about ten or more houses at the maximum.

[0056]

As described above, according to the present invention, even if there is a fire alarm due to cigarettes, cooking smoke, etc., in this case, the fire is determined to be undecided and a warning alarm is issued at another dwelling unit, It is possible to prepare for the original fire alarm by determining the fire. If the fire was confirmed by the on-site confirmation, by operating the cancel switch after restoring the alarm receiver, other dwelling units were notified that there was no abnormality, and despite the non-fire, There is no trouble that would occur if the fire was immediately confirmed by a fire alarm and a warning was given, so that non-fires could be dealt with in all the dwelling units of the group and mutual monitoring would assure the reliability of the system. it can.

When a fire is confirmed in a state in which a caution alarm is given as fire undecided, a fire occurrence switch can be immediately alarmed by pressing a fire confirmation switch, and the fire of a dwelling unit which is performing mutual monitoring can be immediately performed. With the cooperation, early fire extinguishing can be performed quickly. In addition, assuming a case in which the fire is not activated and the fire confirmation switch cannot be pressed due to the initial fire extinguishing etc. in the state of the caution alarm due to the fire undecided, the automatic fire confirmation by the two-line alert will surely alert other dwelling units from the warning alarm to the fire alarm Even if a switchover notification can be made and a two-stage warning notification of a fire unconfirmed caution alarm and a fire conclusive warning is given, it is possible to respond quickly and appropriately to an emergency such as a fire.

Further, regarding the notification that there is no abnormality by the cancel switch, if two or more dwelling units are canceled in an alarm state, the alarm state of an abnormally-occurring dwelling unit in which the alarm is not canceled is inconsistent. When a warning is issued for a dwelling unit, the warning for the dwelling unit that sent the cancellation notification is terminated without outputting the sound of the cancellation of the alarm, and the confusion caused by the cancellation notification when abnormalities occur in multiple dwelling units is reliably prevented. it can.

Further, when an abnormality occurs in two or more dwelling units, the dwelling unit light indicating the abnormal dwelling unit blinks during the output of the voice alarm message, and the dwelling unit light is switched to the lighting state when the output of the voice alarm message is completed. Even if there are a plurality of abnormal dwelling unit displays, it is possible to surely recognize which dwelling unit is outputting the sound at that time, and it is possible to reliably prevent confusion with the occurrence of an abnormality in a plurality of dwelling units.
