Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fire receiver equipped with various kinds of indicator lights, operation switches and the like to monitor and notify the occurrence of a fire.

[0002]

2. Description of the Related Art Conventionally, a plurality of fire detectors are connected to a fire receiver via a detector line, and when any one of these fire detectors issues a warning or when the detector line is detected. When the transmission button of the transmitter connected in parallel with the fire detector is operated, the fire lights and district lights are turned on, and the fire alarm is sounded from the main sound and district sound to guide residents to evacuate. Those that deal with such issues are becoming widespread.

[0003] In this type of fire receiver, when the alarm of the fire detector is a false alarm or the operation of the transmitter is a mischief, each switch is operated to switch from the main sound and the district sound. The fire alarm can be stopped, the fire receiver can be restored to the original monitoring state, and fire monitoring can be continued.

[0004]

However, in the above-mentioned conventional fire receiver, the configuration and notation of each switch operated in the event of a fire are intended for a well-trained professional surveillance staff. Therefore, especially when a person who is unfamiliar with the operation falls into a panic state, there is a possibility that the notification of fire, fire extinguishing activities, evacuation guidance of residents, etc. may be delayed because the operation method of each switch is unknown. It was

On the other hand, at the time of non-fire, the alarm output of the main sound and district sound is stopped, and the restoration operation is performed so as to return to the original monitoring state, but at this time, the operation for canceling the alarm ringing is forgotten. If this condition is left unattended, the local sound linked to the notification of the fire detector cannot be activated when a real fire occurs, which may delay the evacuation of residents. . In order to prevent this case, a switch caution light is provided to indicate that the operation switch to be returned has not returned to the fixed position, but since only one caution light is provided for the fire receiver. , When this was lit, it was not possible to clearly determine whether the cause was that the district acoustic stop was not released or the other operation switches were not returned to their original positions.

Further, in the above-described conventional fire receiver, when a transmitter light indicating that the transmitter button of the transmitter has been operated is provided, once the transmitter button of the transmitter is operated, it remains lit. (Latch display) When the recovery button of the transmitter is already operated, the fire receiver cannot see it. For this reason, even if the transmitter button is operated by mischief or the like and the receiver side subsequently determines that there was no fire, and if recovery operation is performed, if the transmitter side has not performed recovery operation, the fire receiver will not It worked many times, and it took time to return the entire system to the normal fire monitoring state.

In other words, with the conventional transmitter light, when the fire is restored, it is not possible to determine whether the transmitter button of the transmitter has been operated or has already been restored, so it is necessary to check the installation location of the transmitter each time. It may be necessary, and it is not clear to the person who operates the fire receiver that the transmitter light will turn on and off, so it is necessary to perform recovery operations many times or not operate normally. I sometimes misunderstood.

Further, as described above, the conventional fire receiver is provided with a switch caution light indicating that there is an operation switch that has not been restored, but the target of this is the monitoring state. Since it is only an operation switch that requires a return operation to return it (for example, a district sound stop switch), an operation switch that does not remain in a normally operated state (for example, a battery test switch) is not included. For example, when the operation switch fails and is kept in the operated state, it may be left as it is and may not operate normally in a real fire or the like.

The present invention has been made in view of the conventional problems described above, and by instructing the operation of each switch by an appropriate display, even a person unfamiliar with the operation can operate each switch. A first object of the present invention is to provide a fire receiver that is simple and accurate, and that can quickly respond to a fire and a non-fire. A second object is to provide a fire receiver in which the state of button operation of the transmitter can be easily understood by clarifying the timing of turning on and off the transmitter light.

A third object is to prevent an erroneous operation in an actual fire or the like by preventing continuation of operation more than necessary even for an operation switch which normally does not remain in an operated state. It is to provide a fire receiver that is prevented from happening.

[0011]

DISCLOSURE OF THE INVENTION The present invention has been proposed in order to achieve the above first to third objects, and in a fire receiver according to claim 1, a site confirmation lamp near a fire lamp. When any of the fire detectors connected to the detector line is notified, the site confirmation light is turned on or blinks together with the fire light to check the situation of the installation location of the fire detector. Give instructions.

The fire receiver according to claim 2 is provided with a fire response display section for displaying a countermeasure when the occurrence of a fire is confirmed, and when any one of the fire detectors connected to the detector line gives an alarm. As a result of confirming the situation of the installation location of the fire detector that has been notified by the display on the fire response display section, the user will be instructed what to do when a fire occurs. Further, in claim 3, a plurality of coping methods when a fire occurs are displayed in characters on the fire response display portion.

Here, there are "119 number", "initial fire extinguishing", "evacuation guidance", etc. in the coping method shown on the fire response display section, and this display section is turned on when the fire detector reports. It may be turned on and off, and the observer who sees this can know all the things to be dealt with at the same time, so that the fire can be dealt with quickly. The fire receiver according to claim 4 is provided with a district sound stop switch that is operated to stop the ringing of the district sound connected to the district sound line to a prohibited state, and the district sound stop switch includes a sound stop light. When any one of the fire detectors connected to the detector line is activated and the district sound stop switch is operated, the sound stop light is turned on or blinks at the same time to stop the sound of the district sound. Until it is released, this lighting and blinking state is maintained.

According to another aspect of the fire receiver of the present invention, a recovery switch operated to restore the fire receiver to the monitoring state,
It is equipped with a stop release switch that is operated to release the setting to stop ringing the district sound, and a recovery operation unit that has a stop release display section that displays instructions for operating this stop release switch, and is connected to the sensor line. If any of the fire detectors fired, then operate the recovery switch,
The fire receiver returns to the monitoring state, and at this time, the district sound is set to be stopped, and if the stop release switch is operated according to the display of the stop release display section, the district sound can be activated.

According to a sixth aspect of the present invention, in the restoration operation section of the fifth aspect,
An arrow lamp is provided near each of the recovery switch and the stop release switch, and these arrow lights sequentially light up or blink to guide the operation of the recovery switch and the stop release switch. As a result, if the switch operation is performed according to the arrow light, it is possible to easily restore the monitoring state in the non-fire state and prevent forgetting the operation.

According to another aspect of the fire receiver of the present invention, the detector line is provided with a transmitter light indicating an operating state of a transmitter connected in parallel with the fire detector. The transmitter light is operated by a transmitter button of the transmitter. It lights up or flashes when turned on, and goes off when the recovery button of this transmitter is operated. In the eighth aspect, a transmitter state display unit is provided near the transmitter light of the seventh aspect, which indicates that the transmitter button of the transmitter is operated and the recovery button is not operated. Since this display part shows concrete and easy-to-understand contents such as "the transmitter is pressed", the relation between the transmitter light and the button operation state of the transmitter becomes clear.

In the fire receiver according to claim 9, the operation switch which does not require a return operation when returning the fire receiver to the monitoring state is provided with a switch abnormality light indicating that the operation switch remains in the operated state. The switch abnormality light indicates that the operation time of the operation switch has exceeded the preset time.
Lights or flashes. In addition, as a switch abnormal light,
It is also possible to deal with it by blinking the switch caution light and the trouble display light.

In the fire receiver of the tenth aspect, when the fire receiver is returned to the monitoring state, the operation switch that does not require a return operation causes a switch abnormal sound that outputs a sound indicating that the operation switch is still being operated. This switch abnormal sound outputs a switch abnormal sound when the operation time of the operation switch exceeds a preset predetermined time. here,
Switch abnormal sounds include signal sounds and voice messages,
The main sound may be used for the switch abnormal sound.

In the eleventh aspect of the present invention, in the ninth or tenth aspect, the predetermined time for determining the abnormality of the operation switch is set to a time longer than a predetermined time until the automatic return type switch returns. At 12, a time that is twice this fixed time is set. As a result, even if the operation switch that is not normally operated continues to hold the operation state more than necessary, the abnormality can be detected early. Note that the target automatic reset switch may be, for example, one that takes the longest time to restore.

[0020]

There are provided a switch caution light 32 indicating that the operation switch has not been restored, and a trouble display light 33 indicating that there is an abnormality such as disconnection of the sensor line.

Next, the configuration of a fire monitoring system using this fire receiver A is shown in FIG. The fire alarm receiver A is connected to a detector line L1 to which a fire detector S is connected and a district sound line L2 to which a district sound B is connected.
When any one of the fire detectors S connected to 1 fires, the fire light 1 provided in the fire receiver A and the district light 3 of the warning area corresponding to the fire detector S that fired are turned on. At the same time, the main sound 6 and the district sound line L2 are connected, and the district sound B corresponding to the fire detector S that issued the alarm is sounded.

The fire receiver A is connected to a fire detector S having a call button P1 and a recovery button P2 in parallel with the fire detector S in the detector line L1. A transmitter response line La is provided in order to distinguish between the issuance of the message and the operation of the transmitter button P1 of the transmitter P and to detect the operation of the recovery button P2 of the transmitter P. Subsequently, an example of the internal configuration of the fire alarm receiver A is shown in a block diagram in FIG.

Inside the fire alarm receiver A, a signal processing section 50 which is composed of a CPU or the like and controls each section, the main sound 6 shown in the external view of FIG. 1, and various indicators and a display section are provided. Group 51 and switch group 52 including various operation switches

Each of the display groups 51 is composed of an LED, a liquid crystal screen or the like, and lights or blinks as needed, and each of the switch groups 52 has a push button type switch, a rebound type switch, or an automatic reset type. It is composed of switches. Next, the basic operation and basic operation procedure of the fire alarm receiver A will be described with reference to FIGS. Figure 4 (# 1
~ # 3) is triggered by fire detector S or transmitter P
After the operation is performed, the site confirmation is performed and it is determined that the actual fire occurs, and FIG. 5 (# 11 to # 26) is the case where the non-fire is determined.

Fire detector S connected to detector line L1
Is issued, or call button P of transmitter P
1 is operated, in the fire alarm receiver A, the fire lamp 1, the corresponding district light 3, the site confirmation light 2, and the transmitter light 13 when the transmitter P is operated, or At the same time as blinking, the main sound 6 and the district sound B via the district sound line L2 ring (# 1).

Then, the supervisor or the like confirms the situation of the site according to the instruction of the site confirmation light 2, and if the occurrence of a fire is confirmed,
According to the instructions of the fire response display unit 4, the fire department is notified of the number 119, the initial fire is extinguished, and evacuation guidance is performed. At this time, since the site confirmation lamp 2 is provided near the fire lamp 1, it is easy to catch the eyes of the surveillance staff member and can take quick action. Therefore, it is possible to recognize this and deal with it without panic.

After that, when the fire is extinguished and the fire is extinguished, the recovery switch 10 is operated (# 2) to return the fire receiver A to the original monitoring state. In other words, when the recovery switch 10 is operated, the fire lamp 1, the district lamp 3, and the site confirmation lamp 2 which are lit or blinking are turned off (transmitter lamp 1
3 is turned off by the operation of the recovery button P2 before the operation of the recovery switch 10, and the ringing of the main sound 6 and the district sound B is stopped (# 3).

On the other hand, when it is confirmed that there is no fire, FIG.
As shown in, the main sound stop switch 5 and the district sound stop switch 7 are operated to stop the main sound 6 and the district sound B (# 12 to # 15). At the time of operating the district sound stop switch 7 at this time, the sound stop lamp 7a simultaneously lights up or blinks (# 16), and thereafter, that state continues until the stop release switch 8 is operated. Also, if the stop release switch 8 is not operated, the district sound B will not ring when the monitor returns to the monitoring state. Therefore, the switch warning light 32 is turned on to call the attention of the watchman (# 17).

After that, the cause of the fire detector S is removed or the return button P2 of the transmitter P operated by mischief or the like is operated (the transmitter lamp 13 is turned off) to execute the recovery operation. In the case of non-fire, it is necessary to return the fire receiver A to the original monitoring state promptly, so when the main sound 6 and the district sound B are stopped, the down arrow light 9 lights or blinks, and the recovery switch. Instruct 10 operations (#
18).

When the restoration switch 10 is operated in accordance with this (# 19), the fire lamp 1, the district lamp 3 and the site confirmation lamp 2 which are on or blinking are turned off (# 20), and then the up arrow lamp 11 is turned on. Lights up or flashes, and the stop release indicator 1
Instructing to operate the stop release switch 8 according to the display of # 2 (# 22). If the stop release switch 8 is operated (# 23), the sound stop light 7 of the district sound stop switch 7
a is extinguished (# 24), and the switch caution lamp 32 is extinguished because there is no target operation switch (# 2).
6).

As described above, the recovery operation is complicated when there is no fire, but the operation procedure is guided by the arrow lights 9 and 11,
As for the restoration of the district sound B, since the sound stop lamp 7a and the stop release display section 12 are provided, even a specialized monitor or an unfamiliar person can surely operate. Further, since the trigger for turning on and blinking the transmitter light 13 is clearly the time when the transmitter button P1 of the transmitter P is operated and the time when the recovery button P2 is operated, the transmitter P is not yet recovered. , There is no need to repeat the recovery operation on the fire receiver A side.

Next, the function of detecting a switch abnormality will be described. Of the switch group 52, when the operation switch that needs a return operation to keep the fire receiver A returned to the monitoring state is still being operated, as described with reference to FIG. , Requesting the return operation. For example, the district sound stop switch 7 is a switch warning light 32 unless the stop release switch 8 is operated.
Is lit up.

Therefore, in the present invention, in addition to the operation switches of this type, the operation switches that normally do not require a return operation to return to the monitoring state are still in operation and the operation time is When the predetermined time set in advance is exceeded, the switch caution light 32 is turned on or blinks as a switch abnormality light, and the main sound 6 is output as a switch abnormality sound.
Switch abnormal sound (for example, a signal sound such as "beep" or a voice message such as "the operation switch has a problem") is output.

For example, the battery test switch 24 (see FIG. 1) is the target operation switch. Normally, when this switch is operated, the capacity of the standby power supply is checked, and if this capacity is sufficient to back up during a power failure, the test result lamp 24a is turned on. When an abnormality occurs in 24 and it remains in the operated state, this test connects a pseudo load to the standby power source to detect its capacity, so that this capacity decreases as time passes, When an actual power failure occurs, backup cannot be performed. Therefore, in order to prevent it, it is necessary to inform the monitoring staff of the abnormality of the switch. It should be noted that there is another rebound type switch as the target switch, and even in this case, if this switch cannot be automatically restored, a switch abnormality can be detected.

During the predetermined time for judging the above-mentioned switch abnormality, an automatic recovery type switch (for example, the fire test switch 2) which automatically recovers after a predetermined fixed time when operated.
A time longer than the fixed time of 1), specifically, a time about twice this fixed time may be set. FIG. 6 is a flowchart showing the basic operation (steps 100 to 10).
4). Here, when a switch operation is performed, a timer (not shown) starts timing, and if the operation time exceeds a preset predetermined time, the switch caution light 32
And the switch abnormality message is output from the main sound 6 at the same time to notify the switch abnormality. When the switch abnormality is notified in this manner, the monitor member may inspect and repair each switch.

[0037]

As described above, the fire receiver of the present invention has the following effects. According to claim 1, since the site confirmation light is provided near the fire light,
When a fire detector is reported, the monitoring staff can look at the site confirmation light and take prompt action to confirm the site where the fire detector is installed.

According to claims 2 and 3, since a method of coping with the occurrence of a fire is shown on the fire-corresponding display section, it suffices to take action according to the displayed contents. All the things that should be done are known at the same time, so you can quickly respond to a fire without any confusion. Claim 4
According to the report, if the district sound stop switch is operated after the fire detector is activated, the sound stop light will be turned on or blink at the same time, and this lighting and blinking state will continue until the stoppage of the district sound is released. Since it is retained, the observer will not forget to cancel the stop of the district sound during the recovery operation.

According to the fifth aspect, the fire receiver can be returned to the monitoring state by operating the recovery switch after the fire detector has issued a warning, but at this time, the district sound is set to be stopped. In this case, since the stop release display unit instructs the operation of the stop release switch, it is possible to prevent the district sound from ringing when the fire detector is activated after the recovery. According to claim 6, an arrow lamp is provided for each of the recovery switch and the stop release switch, and these arrow lights sequentially light up or blink to guide the operation of the recovery switch and the stop release switch. If the switch is operated according to the light, it is possible to easily and accurately restore the monitoring state when there is no fire.

According to the seventh and eighth aspects, the transmitter light is turned on or blinks from the time the transmitter button is operated until the recovery button is operated so as to match the button operation state of the transmitter. Since there is no need to go to the place where the transmitter is installed to check whether the transmitter's call button is still being operated or whether it has already been restored, when the fire is restored, as in the past. In particular, claim 8
As a result, the meaning of turning on the transmitter light has been clarified, so that there is no need to perform an unnecessary recovery operation.

According to the ninth to twelfth aspects, since it is informed that the operation switch which does not require the returning operation when the fire receiver is returned to the monitoring state is in the operated state, the operating state is changed. It is possible to prevent from being left as it is and not operating normally in a real fire. In particular, according to the eleventh and twelfth aspects, since the predetermined time for judging the abnormality of the operation switch is based on the time until the automatic return type switch is returned, the switch is operated in spite of the normal operation. It is possible to detect the switch abnormality at an early stage without judging that it is abnormal or that the switch abnormality has occurred and the state is not left for a long time.
