DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring and control system having a function of controlling the sound of a district acoustic device.

[0002]

2. Description of the Related Art In general, fire alarm equipment is provided in each monitoring area.
(Each district), which detects fires based on smoke, temperature, etc., and outputs a fire signal when a fire is detected. A transmitter that outputs a fire signal by operation and a local sound such as a bell or buzzer that is installed at a place that manages fire alarm equipment and receives fire signals from the above detectors and transmitters and issues an alarm to the monitored area There is provided a receiver for outputting an operation signal for operating the apparatus and other facilities / equipment corresponding to a fire.

[0003] Here, the receiver is provided with a switch for stopping the sound of the district sound device. When the switch is operated in the receiver, the sound of the district sound device in each monitored area is sounded. Are stopped, and it is possible to cope with misinformation, maintenance work, and the like.

[0004] By the way, a mechanical lock type switch is generally used as a switch for stopping the local sound. For example, a worker or the like operates the switch to turn it on during maintenance and inspection. If the user forgets to return, the district sound system cannot be sounded even if a fire signal is input from a sensor or transmitter, and the district sound system will not sound despite the fire alarm. May occur.

[0005]

SUMMARY OF THE INVENTION In order to avoid such a problem, the inventors of the present application have proposed a switch for stopping the sound of a district sound apparatus, a district sound stop switch, a collective district sound switch, and a receiver. A technology for providing an acoustic stop switch has been devised.

That is, the collective sound stop switch has the same function as the conventional switch for stopping the area sound,
For example, a mechanical lock-type switch is used, and when this switch is operated (turned on), the local sound device is held in a sound stop state, and unless this switch is operated again (for example, this Unless the switch is returned to the sound stop release side), even if a fire signal is received at the receiver, the sound stop state of the district sound device is maintained.
That is, when the collective sound stop switch is operated (turned on) and the district sound device stops sounding, input of a predetermined signal from a sensor or a transmitter is performed unless the collective sound stop switch itself is operated again (turned off). In some cases, the ringing stop state is not released.

On the other hand, even if the local sound stop switch is operated and the local sound device stops sounding, the fire signal is input from the detector or the transmitter (input of the first report).
In this case, the predetermined time is counted by the timer from this point, and when the predetermined time has elapsed, the sound stop state of the regional sound device is released, and even before the predetermined time is counted by the timer. Input of a fire signal from a transmitter or sensor different from the transmitter or sensor that output the first report (second
(Input of information), the sound stop state of the district sound device is released, and the district sound device is set to a sound audible state. For example, a non-lock type switch is used as the local sound stop switch.

By the way, in a receiver having two types of local sound stop switches (district sound stop switch and collective sound stop switch) having different functions as described above, for example, a failure of a certain sensor causes a failure. If a fire signal is continuously input from the sensor, the district sound device will sound again after a predetermined time has elapsed even if the sound of the district sound device is stopped by the district sound stop switch.

Therefore, in such a case, it is desirable to set the district sound device to the ringing stop state by the collective sound stop switch. However, when the collective sound stop switch is used,
Even if a new fire signal is input, the sound of the district sound device remains stopped, and it is impossible to report the fire occurrence. In particular, the collective sound stop switch is mainly used during maintenance and inspection.In this case, if the maintenance and inspection worker forgets to return the collective sound stop switch after the work is completed, even if the receiver receives a fire signal. However, there is a problem that a fire occurrence cannot be notified.

[0010] According to the present invention, when the district sound apparatus is set to the sound stop state, the sound stop state is released even when a predetermined time has elapsed from the time when a predetermined signal is input (input of the first report) from a terminal.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a configuration example of a monitoring control system according to the present invention. In the example of FIG. 1, the monitoring control system is installed in a monitoring area (area) Aa,
(For example, a fire), sensors Da1 to Dan that output a predetermined signal (for example, a fire signal) and a monitoring area Aa
, A transmitter Pa that outputs a predetermined signal (for example, a fire signal) when a predetermined operation is performed, and a monitoring area A
and a detector D which is installed in the monitoring area (area) Ab and outputs a predetermined signal (for example, a fire signal) when detecting a predetermined event (for example, a fire).
b1 to Dbm, a transmitter Pb installed in the monitoring area Ab and outputting a predetermined signal (for example, a fire signal) when a predetermined operation is performed, and a district sound device Bb installed in the monitoring area Ab, Sensors Da1 to Da1 of each monitoring area Aa, Ab
Dan, transmitter Pa, detectors Db1 to Dbm, transmitter P
and a receiver 100 having a function of controlling the local acoustic devices Ba and Bb based on the input of a predetermined signal (for example, a fire signal) from b.

That is, in the example of FIG. 1, the terminals Da1 to Dan, which detect the predetermined event or output a predetermined signal when a predetermined operation is performed, are used as terminals.
Db1 to Dbm and transmitters Pa and Pb are used.

In the example of FIG. 1, the receiver 100 includes:
Sensors Da1 to Dan installed in the monitoring area Aa
When a predetermined signal is input from any terminal of the transmitter Pa, at least the district sound device Ba installed in the monitored area Aa is driven to sound, and the monitored area Ab is also driven.
When a predetermined signal is input from any one of the sensors Db1 to Dbm and the transmitter Pb installed in the monitoring area Ab, the local sound apparatus Bb installed in at least the monitoring area Ab
Drive means 1 for driving and sounding, and first sound stop means 2 for stopping the sound of the local acoustic devices Ba and Bb.
And the second to stop the sound of the district sound devices Ba and Bb
Sound stopping means 3, a third sound stopping means 4 for stopping sound of the district sound devices Ba and Bb, and a district sound device B
a stop release means 5 for releasing the sound stop state of a and Bb;
Sensors Da1 to Dan, Db1 to Dbm, transmitter Pa,
When a predetermined signal is input from any terminal of Pb, a timer 6 for counting a predetermined time from this point is provided, and the stop canceling means 5 stops sounding by the third sound stopping means 4. As for the state, after the local sound devices Ba and Bb are set to the sound stop state by the third sound stop means 4, a predetermined signal is input from a terminal and a predetermined time is counted from this time, or Even before the predetermined time is measured, when the predetermined signal is input from a terminal different from the terminal that has output the predetermined signal from which the measurement of the predetermined time is started, the local acoustic device B
a, Bb is released from the sound stop state, and the stop release means 5 is provided by the second sound stop means 3 for the sound stop state by the second sound stop means 3 for the sound stop state by the second sound stop means 3.
After a and Bb have stopped sounding, when a predetermined signal is input from a certain terminal and a predetermined signal is input from a terminal different from the terminal, the local acoustic devices Ba and Bb are input.
Is stopped, and the stop canceling means 5 sets the first sound stopping means 2 so that the first sound stopping means 2 sets the district sound devices Ba and Bb to the sound stopped state. After that, even if a predetermined signal is input from the terminal, the release control is performed so as not to release the sound stopped state of the district sound devices Ba and Bb based on the input of the predetermined signal.

Here, the first, second, and third sound stopping means 2, 3, and 4 are driven by an operator's operation instruction (for example, operation of a corresponding switch as described later). , And the regional sound devices Ba, Bb
Are common to each other in that the sound stop state is set, but the conditions for automatically canceling the sound stop state are different as described above.

That is, when the sound is stopped by the third sound stopping means 4, the sound stopping state is the third sound stopping state.
After the sound is stopped by the sound stopping means 4, when a predetermined signal is input (first report) from a certain terminal and a predetermined time is measured from this time, or before the predetermined time is measured. Even when there is a predetermined signal input (second report) from a terminal different from the terminal that has output the predetermined signal from which the timing of the predetermined time is started, the stop release is performed on condition that this is input. The means 5 is automatically released by the means 5 and the second sound stopping means 3
When the sound is stopped by the second sound stop means 3, a predetermined signal is input from a certain terminal (first report) after the sound is stopped by the second sound stop means 3. Input of a predetermined signal from a terminal different from
Information), the stop release means 5
When the first sound stop means 2 is set to the sound stop state, the sound stop state is not automatically canceled. I have.

The stop releasing means 5 has a function of manually releasing the sound stop state in addition to the automatic releasing function as described above. For example, after the switch corresponding to the first, second or third sound stop means 2, 3 or 4 is operated to stop sound, the stop release means 5 is operated again, for example, after the switch is operated. sometimes
The configuration may be such that the ringing stop state of the district sound devices Ba and Bb is released (by the second operation). In this case, the first sound stop means 2 causes the area sound device B
When a and Bb are in the sound stop state, the sound stop state is released only when the switch corresponding to the first sound stop means 2 is manually operated again.

As described above, the first, second, and third sound stop means 2, 3, and 4 have different conditions for automatically canceling the sound stop state set thereby, respectively.
Due to such a difference, the uses of the first, second, and third sound stopping means 2, 3, and 4 can be respectively different.

Specifically, when the first sound stop means 2 is set to the sound stop state, the sound stop state of the district sound devices Ba and Bb is not released even if a predetermined signal is input from the terminal. Therefore, the switch corresponding to the first ringing stop means 2 is mainly used only for maintenance (maintenance) (for example, only for maintenance and inspection workers), and is used by general users. Can be prevented from being used. That is, after the switch corresponding to the first ringing stop means 2 is operated to be in the ringing stop state, even if a predetermined signal is input from the terminal, based on the signal, the district sound devices Ba, Bb Is not released, and if this is operated (erroneously) by a general user, the sound stop state of the district sound devices Ba and Bb is not released even if a fire or the like occurs, and the district sound device Ba is not released. , Bb do not ring, which is undesirable, and is therefore not
(For example, only maintenance workers) should be usable.

Therefore, the switch corresponding to the first ringing stop means 2 can be provided in a place where it is difficult for a general user to operate, for example, inside the housing of the receiver 100. In this case, this switch is used. Is a lock type switch (when this is turned on manually, this on state is maintained until the next manual operation is performed or until a predetermined control signal (electric signal) is applied) It can be.

On the other hand, even if the third ringing stop means 4 is in the ringing stop state by this, when a predetermined signal is input from a certain terminal (first report) and a predetermined time is counted from this point in time. Alternatively, even before the predetermined time is measured, input of a predetermined signal from a terminal different from the terminal that has output the predetermined signal from which time measurement of the predetermined time is started (second report) When there is, the ringing stop state is automatically canceled, so that the switch corresponding to the third ringing stop means 4 can be used by a general user. That is, even if the switch corresponding to the third sound stop means 4 is erroneously operated to be in the sound stop state,
When a fire or the like occurs, for example, after the lapse of a predetermined time, the sound stop state of the district sound devices Ba and Bb can be released and the district sound devices Ba and Bb can be sounded. Therefore, the switch corresponding to the third ringing stop means 4 is provided in a place where the general user can easily operate it (a place where the switch can be used at all times), for example, on the surface of the housing of the receiver 100 or outside the housing. In this case, the switch can be a non-locking switch (a switch of a type in which after being turned on manually, the switch itself is immediately turned off).

As described above, the switch corresponding to the first sound stop means 2 has a function as the collective sound stop switch described above, and the switch corresponding to the third sound stop means 4 is described above. It has a function as a district sound stop switch.

However, the receiver 100 is provided with only the first sound stop means 2 (corresponding to the collective sound stop switch described above) and the third sound stop means 4 (corresponding to the above-described area sound stop switch). Some systems have the disadvantages described above. That is, for example, when a predetermined signal (for example, a fire signal) is continuously input from this terminal due to a failure of a certain terminal or the like, the third sound stop means 4 stops the sound of the regional sound devices Ba and Bb. Even if the state is to be held for a considerably long time, the district sound devices Ba and Bb will sound again after a predetermined time has elapsed.

On the other hand, in such a case, when the first sound stop means 2 is used to set the district sound devices Ba and Bb to the sound stop state, the district sound devices B and Bb are again lit after a predetermined time has elapsed.
Although a and Bb do not sound, even if a new predetermined signal (fire signal) is input (the second report), the sound of the regional sound devices Ba and Bb remains stopped. This makes it impossible to report the occurrence of a fire or the like.
In particular, the first sound stop means 2 causes the area sound device B
When a and Bb are set to the sound stop state, for example, when the maintenance and inspection worker forgets to return the corresponding switch after the work is completed, even if the receiver 100 receives a predetermined signal (fire signal), There is a problem that the occurrence of a fire or the like cannot be notified.

In order to solve such a problem, in the present invention, the second sound stopping means 3 is newly provided. That is, the second sound stop means 3 (a switch corresponding to the second sound stop means 3)
When the local sound devices Ba and Bb are set to the sound stop state by the above, even if an attempt is made to maintain the sound stop state for a considerably long time, a predetermined signal (for example, a fire signal) continues from this terminal due to a failure of a terminal. In this case, the local sound devices Ba and Bb sound again after a predetermined time elapses, and the first sound stopping means 2 (corresponding to this) The second ringing stop means 3 (the switch corresponding to this) is provided in consideration of both the problem that the occurrence of a fire or the like cannot be notified if the user forgets to return the switch. It is intended to be used by both general users and maintenance and inspection workers.

However, regarding this kind of district acoustic control,
In particular, the first ringing stop means 2 (the corresponding switch)
It is important to solve the problem that the occurrence of a fire or the like cannot be notified if the user forgets to return the key. In this regard, the second ringing stop means 3 (the switch corresponding to this) is particularly suitable for the first key. This is provided in consideration of the problem in the sound stopping means 2. Therefore, it is considered that the second ringing stop means 3 (the corresponding switch) is often used mainly for maintenance (maintenance) (for example, a method which is particularly lawful for maintenance and inspection workers). It is believed that there is).

From such a viewpoint, the switch corresponding to the second ringing stop means 3 is, like the switch corresponding to the first ringing stop means 2, a place where it is difficult for a general user to operate the switch, for example, the reception switch. In this case, the switch can be provided, for example, by a lock-type switch (when this switch is turned on by manual operation, the on state is changed until the next manual operation is performed, or , A type of switch that is maintained until a predetermined control signal is applied.

As described above, the second sound stop means 3 (switch corresponding thereto) is newly provided in the present invention, and the second sound stop means 3 (switch corresponding thereto) is provided. Is newly provided, after this is operated by a general user or a maintenance / inspection worker, and the district sound devices Ba and Bb stop sounding,
A predetermined signal is input from a certain terminal (first report).
When a predetermined signal is input (a second report) from a terminal different from the terminal, the sound stop state of the regional sound devices Ba and Bb can be released.

That is, for example, when a fire or the like occurs during the work of a general user or a maintenance worker and the receiver 100 receives a new predetermined signal (for example, a fire signal)
(That is, there is a predetermined signal input from a certain terminal (first report), and further, a predetermined signal is input from a terminal different from the terminal.
(If there is a (second report)), the ringing stop state by the second ringing stop means 3 (a switch corresponding thereto) is released, and the district sound devices Ba and Bb are sounding, and the occurrence of a fire or the like is notified. it can. Further, for example, after a general user or a maintenance / inspection worker finishes the work, the second sound stopping means 3
Even if the user forgets to return the switch (corresponding to this), a fire or the like will occur and the receiver 100 will receive a new predetermined signal (for example,
(Ie, when a predetermined signal is input from a certain terminal (first report) and when a predetermined signal is input from a terminal different from the terminal (second report)), the second sound stop is performed. The ringing stop state by the means 3 (a switch corresponding thereto) is released, and the district sound devices Ba and Bb are set to a ringing state, so that the occurrence of a fire or the like can be notified.

In other words, even if the general user or the maintenance / inspection operator forgets to return the switch, or even during maintenance / inspection, the local sound devices Ba and Bb are reliably sounded when a fire or the like occurs. If it is desired to do so, instead of the first sound stop means 2 (corresponding to the collective sound stop switch described above), the second sound stop means 3 (a switch corresponding to this) is required.
Can be operated.

When a general user or a maintenance / inspection operator operates the second sound stop means 3 (a switch corresponding to the second sound stop means), the local sound devices Ba and Bb enter a sound stop state. Input of predetermined signal from
The lapse of a predetermined time from the point of (input of the first report)
This is not a condition for canceling the sound stop state. For example, even when a fire signal is continuously input from this terminal due to a failure of a certain terminal, the local sound devices Ba and Bb sound again after a predetermined time has elapsed. It is possible to prevent that situation. That is, after the predetermined time has elapsed, the district sound device B
It is possible to prevent a situation in which a and Bb sound and hinder maintenance work.

In particular, the second ringing stop means 3 (switch corresponding to this) is used, for example, when a maintenance / inspection operator operates it to perform maintenance / inspection work, for example, due to a failure of a certain terminal or the like. Even if a fire signal is continuously input from this terminal, the district sound devices Ba and Bb can be maintained in the sound stop state without the district sound devices Ba and Bb ringing again after a predetermined time has elapsed. In addition, even if the second sound stop means 3 (switch corresponding thereto) is forgotten to be returned after the work is completed, the sound stop state is released when the probability of occurrence of fire or the like is high. It is considered to be particularly useful when performing maintenance work by an operator.

When the switch corresponding to the second sound stop means 3 is provided inside the housing of the receiver 100, the switch corresponding to the first sound stop means 2 is provided inside the housing of the receiver 100. Can be common with switches. That is, a common switch component can be used for the first sound stopping means 2 and the second sound stopping means 3.

When a common switch component is used for the first ringing stopping means 2 and the second ringing stopping means 3, as shown in FIG.
It is necessary to further provide a selecting means 7 for selecting which function of the sound stopping means 2 and the second sound stopping means 3 is used. That is, for the common switch component, the first sound stop means 2 is selected by the selection means 7.
When the switch component is selected to be used, the switch component is caused to function as the first sound stop means 2,
When the selection means 7 has selected to use the function as the function of the second sound stop means 3, this switch component can function as the second sound stop means 3.

As the selecting means 7, a switch or the like which can be switched by a manual operation of an operator can be used. However, in the receiver 100, the operation mode is set to the first sound stopping means 2 and the second sound stopping means 2 as described later. 2 sound stop means 3
Software that switches between
The selection means 7 can also be realized (by execution of the CPU).

However, when the second ringing stop means 3 is opened to the general user, in order to prevent such a selection switching process from being performed unnecessarily by the general user, when the selection switching is performed, for example, a password is required. It is better to input a number or the like. At this time, the switch component shared by the first ringing stop means 2 and the second ringing stop means 3 is always provided inside the housing of the receiver 100 because a password or the like is input by an operator. You don't have to. That is, in order to use the common switch component as the first ringing stop means 2, it is necessary to input a password, and if the password is not input, the common switch component is used for the first ringing. Since it cannot be used as the stopping means 2 and safety is improved,
In this case, this common switch component is
For example, a non-locking type switch may be provided on the surface or outside of the housing 0.

In the monitoring and control system having the configuration shown in FIG. 1 or FIG. 2, for example, any one of the terminals of the sensors Da1 to Dan and the transmitter Pa installed in the monitoring area Aa issues an alert, and When an input of a predetermined signal from any one of the terminals Da1 to Dan and the transmitter Pa is detected in the receiver 100, the ringing driving means 1 of the receiver 100 outputs an operation signal to the local acoustic device Ba to monitor. The district sound device Ba in the section Aa is sounded. In addition, district sound system B
output an operation signal to the local sound device B in the monitoring area Aa
After sounding “a”, for example, control may be performed such that an operation signal is output to the district sound device Bb to sound the district sound device Bb in the monitoring area Ab.

On the other hand, in the receiver 100, the first and second
Alternatively, when the third sound stop means 2, 3 or 4 is driven, the sound stop means 2, 3 or 4 puts the local sound devices Ba and Bb in all the monitored areas Aa and Ab into a sound stop state, for example. As described above, in the case where the first, second, or third sound stop means 2, 3, or 4 of the receiver 100 causes the local sound devices Ba, Bb of the monitored areas Aa, Ab to be in the sound stopped state, the monitored area Aa , Ab detector Da1
~ Dan, Db1 ~ Dbm, any of the transmitters Pa, Pb emits a signal (for example, the sensor Db1 emits), and a predetermined signal (first report) is sent from the issuing terminal (sensor Db1). When input to the receiver 100, the receiver 100
Is started, and the timer 6 measures a predetermined time from this point.

However, when the ringing stop state is set to the ringing stop state by the first ringing stop means 2, the stop releasing means 5 receives a predetermined signal input from the terminal (for example, the first report). However, based on this, the sound stop state of the district sound devices Ba and Bb is not released. That is, when the switch corresponding to the first sound stop means 2 is operated (turned on) and the local sound devices Ba and Bb are in the sound stop state, the switch itself corresponding to the first sound stop means 2 is operated again. Unless turned off, the ringing stop state is not automatically canceled based on the input of a predetermined signal from the sensor or the transmitter.

When the ringing stop state is set to the ringing stop state by the third ringing stop means 4, the stop release means 5 outputs the sensors Da1 to Dan, Db1 to Db.
m, one of the transmitters Pa, Pb issues a notification (for example, the sensor Db1 issues a notification), and the terminal that issued the notification (the sensor Db
From the time when the predetermined signal (first report) is input to the receiver 100 from 1), when the predetermined time is measured by the timer 6 or before the predetermined time counted by the timer 6 elapses. However, a terminal (for example, the sensor Dbn) that is different from the terminal (the sensor Db1) that has issued the predetermined signal (the first report) emits a signal, and a predetermined signal (the second report) is transmitted from the terminal (the sensor Dbn). ) Is input to the receiver 100, the sound stop state of the district sound devices Ba and Bb is automatically released (the district sound devices Ba and Bb are automatically returned to the sound-enabled state). That is, in this case, even when the predetermined signal (second report) is not input to the receiver 100, the ringing stop state is automatically released when the predetermined time is measured by the timer 6.

On the other hand, when the ringing stop state is set to the ringing stop state by the second ringing stop unit 3, the stop releasing unit 5 sets the sensors Da1 to Dan, Db1.
~ Dbm, one of the transmitters Pa, Pb gives an alert
(For example, the sensor Db1 emits a signal), a predetermined signal (first signal) is input to the receiver 100 from the terminal (sensor Db1) that has issued the signal, and the predetermined signal (first signal) is further generated. Only when a terminal (sensor Dbn) different from the terminal (sensor Db1) emits a signal and a predetermined signal (second signal) is input to the receiver 100 from this terminal (sensor Dbn), the local acoustic device is output. B
The sound stop state of a and Bb is automatically canceled (the area acoustic devices Ba and Bb are automatically returned to the sound enabled state).

Thus, for example, a general user or a worker operates the second sound stop means 3 (a switch corresponding thereto) at the time of work or the like, and after the work is completed, the second sound stop means 3 is kept in the sound stop state. Even if you forget to put it back,
Even if you forget the (second) operation and forget to release the stop),
A predetermined signal (first report) is input from one of the terminals, and a predetermined signal is transmitted from a terminal different from the terminal that issued the first report.
When the (second report) is input, the local sound devices Ba, Bb
Can be released (returns the district sound devices Ba and Bb to the audible state), and reliably prevents the situation where the district sound device does not sound despite a fire alarm. it can.

On the other hand, if a fire signal is continuously input from one sensor due to a failure of a certain sensor, for example, the second
The ringing stop state by the ringing stop means 3 is not released, and therefore, a situation occurs in which the district sound device sounds again after a predetermined time has elapsed (a situation in which the district sound device sounds again during work). Can be prevented.

As described above, in the monitoring and control system of the present invention, the second sound stop means 3 (switch corresponding thereto) is newly provided, so that the first sound stop means 2 is provided.
(Corresponding to the collective sound stop switch described above) and the above-described inconvenience in a system provided with only the third ringing stop means 4 (corresponding to the above-described district sound stop switch) can be avoided.

FIG. 3 is a diagram showing a specific configuration example of the monitoring control system of FIG. 1 or FIG. 2. In the example of FIG. 3, the sensors Da1 to Dan and the transmitter P in the monitoring areas Aa and Ab are shown.
a, the sensors Db1 to Dbm and the transmitter Pb
0 is connected via one transmission line 51. Also,
The local sound devices Ba and Bb in the monitoring areas Aa and Ab are connected to the receiver 100 via one transmission line 52.

That is, in the example of FIG.
Dan, transmitter Pa, detectors Db1 to Dbm, transmitter P
b and the local audio devices Ba and Bb each use an analog terminal capable of setting a unique address. In this case, the receiver 100 includes sensors Da1 to Dan, a transmitter Pa, and sensors Db1 to Db1. Dbm, each terminal of the transmitter Pb,
Via the transmission line 51, each is individually called by each unique address (called by address polling), the sensors Da1 to Dan, the transmitter Pa, and the sensors Db1 to Db.
m, and a signal from each of the transmitters Pb. In addition, the receiver 100 includes the local sound devices Ba and Bb.
Are individually called (called by address polling) by the respective unique addresses via the transmission line 52, and are individually driven by the operation signals. In other words, in the example of FIG.
It is configured as a so-called R-type receiver.

When the monitoring control system of FIG. 3 is configured as a fire alarm facility, the detectors Da1 to Da
For n, Db1 to Dbm, for example, a fire detector that detects smoke, heat, and the like generated in a fire is used.

In the example of FIG. 3, the sensors Da1 to Da
Since n, Db1 to Dbm use an analog type sensor (for example, an analog type smoke detector), the sensors Da1 to Dan and Db1 to Dbm are generally transmitted from the receiver 100 respectively. When address polling is performed, information such as smoke density is output.When the level of this information exceeds a predetermined threshold level (for example, a fire alarm level) in the receiver 100, the receiver 100 , And sensors Da1 to Dan, Db1 to Db
From m, it is determined that a predetermined signal (for example, a fire signal) is input.

That is, for example, when address polling of the sensor Da1 is performed and information exceeding a predetermined threshold level is output from the sensor Da1, the receiver 100 outputs a predetermined signal (for example, a fire signal) from the sensor Da1. It is determined that there is an input.

As the transmitters Pa and Pb, for example, a so-called fire alarm which outputs a fire signal as a predetermined signal by manual operation such as breaking a transparent cover and pressing a button is used.

The local sound devices Ba and Bb are sound devices for notifying a fire such as a bell or a buzzer. The sound devices Ba and Bb sound when an operation signal is input from the receiver 100, and are monitored. A function that informs the people who are present of the occurrence of a fire is used.

In the monitoring control system shown in FIG.

Comprises an operation unit 31, an internal operation unit 32, and a display unit 33. Here, the operation unit 31 and the display unit 33
Can be realized, for example, by an operation panel arranged on the surface of the housing of the receiver 100. FIG. 5 is a diagram illustrating an example of the operation panel. In the example of FIG. 5, the operation panel includes sensors Da1 to Dan, a transmitter Pa, and sensors Db1 to Db.

And the like, a touch panel type liquid crystal display unit 42 having a screen display function and an operation input function, a main operation display unit 43 including various operation switches and indicator lights such as LEDs, an alarm sound, etc. , And a printer unit 45 are provided.

FIG. 6 shows an LCD displayed on the liquid crystal display section 42.
7 is a diagram illustrating a display example of a screen. In the example of FIG. 6, various operation switches are normally displayed on the LCD screen.
At the time of a fire alarm, a character display with more detailed contents than the district display is performed. Where the LCD
As the various operation switches displayed on the screen, for example, a “main sound stop switch”, a “district sound stop switch”, and the like are displayed. In the example of FIG. 6, the LCD screen is of a touch panel type. By pointing to a predetermined position on the LCD screen, information corresponding to this position can be input.

Specifically, the main sound stop switch is provided as a switch for stopping the sound of the main sound device 44. The regional sound stop switch is provided as a switch for manually setting the state of all the regional sound devices Ba and Bb to a sound stop state, more precisely, as a switch corresponding to the third sound stop means 4. ing.
In this case, the operator touches the "area sound stop switch" displayed on the LCD screen,
The district sound devices Ba and Bb can be set to a sound stop state.

In the example shown in FIG. 6, the area sound stop switch is a switch mechanism of the touch panel on the LCD screen.
(Non-locking type switch mechanism), but any switch can be used as a regional sound stop switch or the like. For example, a mechanical switch mechanism can be used.

Specifically, when a mechanical switch is used as the local sound stop switch, if the switch is a non-lock type switch, the state can be easily changed by a signal when the switch is operated. . Further, even when a lock-type switch is used, if the switch itself has a function of changing a state by an electric signal, it can be used as a district sound stop switch or the like.

As described above, in the configuration example of FIG. 4, the operation section 31 can be provided with a main sound stop switch, a district sound stop switch, a restoring switch, and the like.
The display unit 33 includes a switch caution light, a fire indicator light,
District indicator lights, district sound stop lights, etc. can be provided.

The operation unit 31 and the display unit 33 can be realized by an operation panel arranged on the surface of the housing of the receiver 100 so that operation by a general user is possible.
The internal operation unit 32 is provided inside the housing of the receiver 100 so that it is mainly operated only by a person who performs maintenance and inspection work.
In the example of FIG. 4, the internal operation unit 32 includes an internal sound stop switch as a switch for stopping the sound of the regional sound devices Ba and Bb. , An internal sound complete stop switch.

Here, the internal sound stop switch and the internal sound complete stop switch are configured as, for example, lock type switches.

The internal sound stop switch and the internal sound complete stop switch are switches for manually setting the state of all the local sound devices Ba and Bb to the sound stop state, similarly to the local sound stop switch. After the sound stop switch, the internal sound complete stop switch and the district sound stop switch are operated and the sound stops,
The conditions for canceling the sound stop state are different from each other.

That is, the internal sound stop switch receives a predetermined signal input (first report) from a certain terminal after the switch is operated and the sound stops, and further receives a predetermined signal from a terminal different from the terminal. When there is an input (second report), on condition of this, the ringing stop state by this switch is automatically released.

When the internal sound complete stop switch is operated to be in a sound stop state, even if a predetermined signal is input from the terminal, the sound stop state by this switch is canceled based on the input of a predetermined signal. Not to be. That is, for example, input of a new predetermined signal (second report)
Even if there is, the sound stop state is not released.

The local sound stop switch is operated when a predetermined signal is input (first report) from a certain terminal after the switch is operated and the sound stops, and a predetermined time is counted from this time, or Even before the predetermined time is counted, when a predetermined signal is input (second report) from a terminal different from the terminal that has output the predetermined signal from which the timing of the predetermined time is started. In addition, on condition of this, the ringing stop state by this switch is automatically canceled.

In other words, in the example of FIG. 4, the internal sound complete stop switch is a switch corresponding to the first sound stop means 2 of the configuration example of FIGS. ), And the internal sound stop switch is provided as a switch (a new switch of the present invention) corresponding to the second sound stop means 3 of the configuration example of FIGS. The local sound stop switch is provided as a switch corresponding to the third sound stop means 4 of the configuration example of FIGS. 1 and 2 (corresponding to the prior art local sound stop switch).

In the above example, the internal sound stop switch and the internal sound complete stop switch are separate switches from each other, but they may be configured as one common switch. In this case, the receiver 100 includes FIG.
As shown in (1), it is necessary to further provide a selection means 7 for selecting whether to use the shared switch as an internal sound stop switch or an internal sound complete stop switch. The complete stop switch can be used by being switched and set by the selection means 7 as necessary. In this case, the selection unit 7 can be realized by, for example, switching and selecting the operation mode of the CPU 21 by software. That is, if the operation mode for the input from the shared switch component is set to “internal sound stop switch” by software, this switch component can function as an internal sound stop switch. If the operation mode for the input from is set to the "internal sound complete stop switch" by software, this switch component can function as an internal sound complete stop switch.

When the monitoring and control system is configured as shown in FIG. 3, the ringing driving means 1 includes the first transmission control unit 26, the CPU 21, the second transmission control The first sound stop means 2 is realized by an internal sound complete stop switch, a CPU 2
1, realized by the second transmission control means 27, and the second sound stop means 3 is an internal sound stop switch, a CPU
21, realized by the second transmission control means 27,
The third sound stop means 4 includes a district sound stop switch, CP
U21 is realized by the second transmission control unit 27, and the stop release unit 5 is realized by the first transmission control unit 26, the CPU 21, and the second transmission control unit 27.
Is realized by, for example, a timer built in the CPU 21.

That is, the first, second, and third sound stopping means 2, 3, and 4 are provided with respective switches, that is,
When the internal sound stop switch, the internal sound complete stop switch, and the district sound stop switch are operated (turned on), the sound stop state is held in a memory such as the RAM 23.
When the setting is made, the sound stop control is performed by the CPU 21 so that the operation signal is not output from the receiver 100 to the regional sound devices Ba and Bb. That is,
When the sound stop state is set and held in the memory such as the RAM 23, the CPU 21 does not supply an operation signal to the local sound device, thereby realizing the sound stop.

The first, second, and third sound stopping means 2, 3, and 4 are operated by corresponding switches, that is, an internal sound complete stop switch, an internal sound stop switch, and a regional sound stop switch. When the sound stop state is held and set in a memory such as the RAM 23, the sound stop state is further changed by the first, second, and third sound stop means 2,
Information on which of the three or 4 ringing stop means is used is R
It can be retained and set in a memory such as the AM 23 so that it can be identified.

The stop releasing means 5 switches the sound stop state of the local sound devices Ba, Bb to the first, second, and third states when a predetermined signal is input from the terminal of the sensor or the transmitter. Depending on which of the ringing stop units 2, 3 and 4 is set by the ringing stop unit (refer to the information stored and set in the memory such as the RAM 23), the ringing stop state is released. Control is realized by the CPU 21.

Here, when the switch corresponding to the first, second or third sound stopping means 2, 3 or 4 is a non-locking switch mechanism, when the non-locking type switch is turned on. Actually, the ringing stop state set when this is turned on is held in a memory such as the RAM 23 (the non-locking type switch is turned off immediately after being turned on). The canceling means 5 does not actually turn off the switch itself, but cancels the sound stop state stored in the memory such as the RAM 23 to make it a sound enable state.

It should be noted that, even if the switch is not only a non-lock type but also a lock type, the local sound devices Ba, B
Whether b is in the ringing stopped state or the ringing enabled state,
It is possible to set and hold in a memory such as the RAM 23. In the following, the sound stop state and the sound enable state are set in the memory such as the RAM 23 regardless of whether the switch is a non-lock type or a lock type. , Shall be retained.

Next, the operation of the monitoring control system having such a configuration (particularly, the case where the switch (internal sound stop switch) corresponding to the second sound stop means 3 is operated) will be described.

First, when a ringable state is set in a memory such as the RAM 23, all the monitoring areas Aa,
Ab's district acoustic devices Ba and Bb are in a soundable state.
At this time, for example, when a predetermined signal (fire signal) is input from the sensor Da1 in the monitoring area Aa, the CPU of the receiver 100
21 detects this, and outputs an operation signal from the second transmission control unit 27 to the local sound apparatus Ba in the monitoring area Aa. Thereby, the district sound device Ba sounds. Note that the receiver 1
00 or at this time, or
Further, an operation signal is also output from the second transmission control unit 27 to the local audio device Bb in the monitoring area Ab, and the local audio device Bb is output.
Can also be sounded.

On the other hand, for example, when the internal sound stop switch is turned on, a sound stop state is set and held in a memory such as the RAM 23. Further, the fact that the sound stop state is caused by the operation of the internal sound stop switch is set and held. You. Then, the local sound devices Ba, B in all the monitoring areas Aa, Ab
b, no operation signal is sent, and the local acoustic devices Ba,
Bb is in a sound stop state. Therefore, for example, even if a certain district sound device is sounding, the sound of this district sound device also stops.

As described above, when the ringing stop state due to the operation of the internal sound stop switch is maintained, the sensors Da1 to Dan, Db of the monitoring areas Aa, Ab are maintained.
When a predetermined signal (fire signal) is input (first report) from, for example, Da1, from any one of terminals 1 to Dbm, the CPU 21
In this case, the built-in timer starts counting time. In this case, the ringing stop state is caused by the operation of the internal sound stop switch.
Is a ringing stop state (a ringing stop state by operating an internal sound stop switch) held in a memory such as the RAM 23 even if this timer measures a predetermined time.
Is not canceled (that is, the sound is not made available).

On the other hand, after the output (input) of the first report, a terminal different from the terminal Da1 that outputs the first report, for example, Pb
When the predetermined signal is input (second report) from, the sound stop state is due to the operation of the internal sound stop switch, and the CPU 21 stops the sound stop held in the memory such as the RAM 23. The state (sound stop state by operating the internal sound stop switch) is released, and the sound is enabled. As a result, the sound stop state of the district sound devices Ba and Bb is released, and the district sound devices Ba and Bb are set to be able to sound, and a warning (fire alarm) can be issued from the district sound devices Ba and Bb.

As described above, according to the present invention, even when the local sound devices Ba and Bb are set to the sound stop state due to the failure of the terminal or the like, if the new predetermined signal (fire signal) is received by the receiver, the local sound is again output. The sound devices Ba and Bb can be sounded. In addition, even if the internal sound stop switch is accidentally forgotten after the maintenance and inspection work, if a new predetermined signal (fire signal) is input, the district sound devices Ba and Bb can be sounded.

Note that, in the configuration example of FIG.
Dan, transmitter Pa, detectors Db1 to Dbm, transmitter P
An analog type terminal capable of setting a unique address is used for each of the local audio devices b and B, Bb. In this case, the receiver 100 is configured as a so-called R type receiver. The present invention can be applied to a case where an on / off type terminal is used for the sensors Da1 to Dan, the transmitter Pa, the sensors Db1 to Dbm, the transmitter Pb, and the local audio devices Ba and Bb. In this case, a so-called P-type receiver is used as the receiver 100.

FIG. 7 shows the detectors Da1 to Dan and the transmitter P
a, a configuration example of a monitoring control system in a case where on / off type terminals are used for the sensors Db1 to Dbm, the transmitter Pb, and the local audio devices Ba, Bb, and the receiver 100 is a P-type receiver. FIG. In the example of FIG.
From the (P-type receiver) 100, local tracks 53a and 53b extend to the monitored areas Aa and Ab, respectively, and the detectors Da1 arranged in the monitored area Aa extend to the local tracks 53a.
~ Dan, the transmitter Pa is connected, and the district track 53
b, detectors Db1 to Db1 arranged in the monitoring area Ab
bm and the transmitter Pb are connected.

Here, the sensors Da1 to Dan, Db1 to Db1
When Dbm is a fire detector, the detectors Da1 to Da
When n, Db1 to Dbm sense a fire as an event,
A fire signal is output as a predetermined signal.

Also, from the receiver (P-type receiver) 100,
In each of the monitoring areas Aa and Ab, the local tracks 54a and 54
b, the district track 54a is connected to the district sound device Ba located in the monitoring area Aa, and the district track 5a is connected to the district track 54a.
4b is a district sound device B located in the monitoring area Ab
b is connected.

In this P-type receiver, the local track 53
a, 53b, 54a, and 54b are a pair of L and C, respectively.
It is configured as a track. FIG. 8 shows the district track 53
Examples of a and 53b are shown. Now, the detectors Da1 to Da1
Paying attention to the connection between Dan and the transmitter Pa, the district track 53
A pair of L and C lines as a, each detector Da1-D
An is connected, and a transmitter Pa is connected to the ends of the pair of L and C lines 53a. A response line 55 extends from the receiver 100.
Is connected to the other end of the transmitter Pa. FIG. 9 (a),
(b) shows a state where the transmitter Pa is off and on, respectively.

In the case of the configuration example shown in FIG.
Has substantially the same configuration as that shown in FIG. 3, but in the example of FIG. 7, instead of the first transmission control unit 26 and the second transmission control unit 27 of FIG. (A potential between the pair of L and C lines), a potential of the local line 53b (a potential between the pair of L and C lines), and a potential of the response line 55, a first interface unit 28 for managing and monitoring, A second interface unit 29 is provided which functions as an interface with the district sound devices Ba and Bb in the areas Aa and Ab.

In the case of the monitoring control system shown in FIG.
No. 00 normally applies a predetermined voltage (for example, 24 V) between a pair of L and C lines (for example, applies 24 V to the L line and keeps the C line at the ground potential). Normally, a potential of 24 V is applied to the circuit 55.

In this state, the pair of L and C lines 53a
When any of the sensors Da1 to Dan connected to the sensor detects a predetermined event (for example, a fire) and issues an alarm (turns on), or the transmitter Pa operates as shown in FIG. 9 (b). When the alarm is issued (turned on), the potential (24 V) between the L and C lines drops. That is, a low impedance state is established between the L and C lines. As a result, in the receiver 100, the sensors Da1 to Da1 installed in the monitoring area Aa.
Predetermined signal (fire signal) from either Dan or transmitter Pa
Can be determined to have been input.

Further, when the transmitter Pa is operated as shown in FIG. 9B to generate an alarm (turned on), the potential (24 V) between the L and C lines drops, and the potential of the response line 55 ( 2
4V), which causes the receiver 100 to output L, C
The line becomes low impedance and the response line 5
When the potential of 5 also drops, it can be determined that the transmitter Pa has been operated as shown in FIG. That is, the receiver 100 can determine that a predetermined signal (fire signal) has been input from the transmitter Pa installed in the monitoring area Aa.

In the configuration example shown in FIG. 7, the terminal that has output the first report and the new terminal that has output the second report (terminal different from the terminal of the first report) are, for example, the same L and C lines (terminals). For example, detectors (for example, Da1 and Da1) connected to 53a)
2), the first report and the second report are transmitted to the receiver 10
In order to detect at 0, a change in the potential between the pair of L and C lines, for example, the local line 53a (a drop in the potential between the pair of L and C lines) is reported (turned on), It is preferable that the configuration be changed stepwise according to the number of transmitters.

For example, the potential drop between the pair of L and C lines when each sensor and the transmitter emits an alarm is, for example, 0.2
When V is V, the sensors Da1 to Dan and the transmitter P
Assuming that only one of the terminals a, e.g., Da1, issues an alert, the potential between the pair of L and C lines is 2 V from 2 V.
The voltage drops to 3.8V by 0.2V. At this time, assuming that the potential of the response line 55 does not change, the receiver 100 can thereby detect that only one of the detectors Da1 to Dan has issued an alert.

Next, the sensors Da1 to Dan and the transmitter P
Assuming that another terminal out of a, for example, Da2 is also alerted, the potential between the pair of L and C lines further drops by 2 V from 23.8 V to 23.6 V. At this time, assuming that the potential of the response line 55 does not change, the receiver 100 can detect that two of the detectors Da1 to Dan have issued an alarm. That is, with such a configuration, it is possible to detect the first report and the second report from different sensors connected to the same L and C lines.

Of course, the terminal that has output the first report and the new terminal that has output the second report (a terminal different from the terminal of the first report) are respectively connected to different L and C lines (for example, 53a and 53b). When it is sufficient to detect the first and second reports only when they are connected (that is, only when the first and second reports are from terminals on different regional lines) When detection is sufficient), a potential change between a pair of L and C lines, for example, a local line 53a (a pair of L and C lines).
The potential drop between the lines) may not be changed stepwise as described above.

Thus, even in the case of the configuration example of FIG.
The local acoustic stop processing and the local acoustic stop release processing of the present invention can be performed (even when the receiver 100 is a P-type receiver).

In the above description, the monitoring control system is specifically configured as shown in FIG. 3 or FIG. 7. However, at least the first and second sound stopping means 2 and 3 and the stopping As long as the function of the releasing means 5 is provided, the present invention is not limited to FIGS.

For example, by further modifying the configuration of FIG.
No. 62), each ON / OFF type sensor can be configured as a sensor for sensor address.

In the above example, the time measuring means 6 (timer)
Although a predetermined signal is input from a terminal, a predetermined time is measured from this point in time, but various conditions can be added to this. That is, the third
In the case where the ringing is stopped by the ringing stop means 4, for example, when there is a predetermined signal input from the terminal, the timer means 6 (timer) continuously inputs the predetermined signal for a predetermined time from this time. On the condition that the predetermined time is longer than a predetermined time, it is possible to release the sound stop state of the district sound device. In this case, the clocking means 6 (timer) measures the time when the predetermined signal is continuously input from the terminal, and is reset when the input of the predetermined signal is stopped. Has become. That is,
When the predetermined signal has been input (continuously input) and a preset predetermined time has elapsed (when the time is up), the clocking means 6 outputs a signal for canceling the ringing stop. 5 can be given.

In the present invention, the timer 6 (timer) is necessary when the third sound stopping means 4 is provided in addition to the first and second sound stopping means 2 and 3. Is done. That is, the monitoring and control system of the present invention has
The second and third sound stop means 2, 3 and 4 may be provided, or the first and second sound stop means 2 and 3
Only two types of sound stopping means may be provided. If only two types of sound stopping means of the first and second sound stopping means 2 and 3 are provided, a timer means (timer) 6 is provided. May not be provided.

Further, in the above-described example, the internal sound stop switch, the internal sound complete stop switch, and the district sound stop switch perform the control of the district sound stop via the CPU 21, but the CPU 21 goes out of control. In order to avoid the situation where the local sound stop becomes impossible in such a case, the switches may directly control the local sound stop for the local sound devices Ba and Bb.

Further, in the present invention, the district sound device B
When a and Bb are in the sound stop state, the display means for displaying which of the first, second, and third sound stop means 2, 3, and 4 has set the sound stop state, The receiver 100 may be further provided. 5 and 6, for example, an LCD screen of the liquid crystal display unit 42 and / or an indicator light (eg, LED) of the main operation display unit 43 can be used. When the sound devices Ba and Bb enter the sound stop state, the liquid crystal display unit 42 determines which of the first, second, and third sound stop means 2, 3, and 4 has set the sound stop state. LCD screen and / or main operation display section 4
When the local sound devices Ba, Bb enter the sound stop state by displaying the information on the three indicator lights (for example, LEDs), the sound stop state is changed to the first, second, and third sound stop means 2, 3, , 4
Can be clearly notified to the operator.

Also, in the present invention, the district sound device B
Display means for displaying a state (a ringing enabled state or a ringing stopped state) for a and Bb may be further provided in the receiver 100. Such display means include:
In the examples of FIGS. 5 and 6, for example, the L
A CD screen and / or an indicator light (for example, an LED) of the main operation display section 43 can be used. Display 43
, The state of the local sound devices Ba and Bb can be clearly notified to the operator.

If the switch corresponding to the first, second or third ringing stop means 2, 3 or 4 is of the non-lock type, the LCD screen of the liquid crystal display section 42 and / or the main operation The state of the switch itself is not displayed on the indicator light (for example, LED) of the display unit 43. To be more precise, for example, a sound stop state, a sound enable state, and the like stored in a memory such as the RAM 23 are displayed. Sound device B
It is displayed as a state for a and Bb. This allows
The display means can accurately display whether the sound of the district sound device has been stopped or the stop has been released.

Specifically, when the switch is configured as a non-locking type, the LCD screen is inverted according to the ringing enabled state and the ringing stopped state set (held) in the memory such as the RAM 23. By changing the color or changing the color, the ringing enabled state and the ringing stopped state can be displayed so that the operator can identify them.

On the other hand, the switch is of a lock type, for example, and a control signal (electric signal) from the stop release means 5, for example.
When the state of the switch itself is switched by the switch, the state (ON state, OFF state) of the switch itself matches the sound stop state and the sound possible state, respectively. Therefore, in this case, the switch is in the off state (sound-enable state)
At the time of, for example, the indicator lamp of the main operation display section 43 (for example, L
ED) is turned off to indicate a ringing enabled state, and when the switch is turned on (sound stopped state), for example, the main operation display unit 4
The indicator light (LED) of No. 3 can be turned on to display a ringing stop state (switch-on state).

When the switch is configured as a lock-type switch mechanism, the sound stop state and the sound enable state of the district sound device correspond to the ON state and the OFF state of the switch. The release is performed by manually operating the switch itself from the ON state to the OFF state, or by electrically switching the switch itself from the ON state to the OFF state, for example. On the other hand, when these switches are non-locking switch mechanisms (for example, a touch panel type LCD screen), when these switches are turned on, the on state (sound stop state) is actually turned on. It is held in a memory such as the RAM 23 (these switches are turned off immediately after being turned on). Therefore, the release of the sound stop state is performed by releasing the on state (the sound stop state) held in the memory such as the RAM 23. This is done by turning it off (ringing enabled state). In this case, strictly speaking, the LCD screen of the liquid crystal display unit 42 and / or the indicator lamp (for example, LED) of the main operation display unit 43 Instead of displaying the state of the switch, to be precise, the ringing stop state and ringing possible state held in the memory such as the RAM 23 are displayed as the state of the ringing stop means. .

Further, in the present invention, the district sound device B
Inputting a predetermined signal from the terminal when the sound of a and Bb is stopped
If there is (for example, the first report), change the display state
(For example, the display screen may be changed from a lighting state to a blinking state).
