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
Driving means 1 for driving and sounding, sound stopping means 2 for stopping sound of the local acoustic devices Ba and Bb, and function changing means 3 for changing the function (mode) of the sound stopping means 2
And display means 4 for displaying which function (mode) of the sound stop means 2 is set, and stop release means 5 for releasing the sound stop state of the district sound devices Ba and Bb.
And sensors Da1 to Dan, Db1 to Dbm, and transmitter P
When a predetermined signal is input from one of the terminals a and Pb, there is provided a timer 6 for counting a predetermined time from this point.

Here, the sound stopping means 2 has a function (mode) for stopping the sound of the district sound devices Ba and Bb as a first function for completely stopping the sound of the district sound devices Ba and Bb unless a manual operation is performed. Mode, and under predetermined conditions on the assumption that a predetermined signal is input from the terminal,
There are two types of modes, a second mode in which the sound stop of a and Bb is automatically canceled.

In other words, when the sound stopping means 2 is set to the second mode, the stop canceling means 5 stops the sound by the sound stopping means 2 and then outputs a predetermined signal from the terminal. Is automatically released from the sound stop state of the regional sound devices Ba and Bb under a predetermined condition on the assumption that the sound input is input, and the stop canceling means 5 sets the sound stop means 2 to the first mode. After the sound is stopped by the sound stopping means 2, the sound stopping state of the district sound devices Ba and Bb is not automatically canceled based on a condition on the assumption that a predetermined signal is input from the terminal. Release control is performed.

The function changing means 3 is configured to change the function (mode) of the sound stopping means 2 for switching.

More specifically, for example, the sound stopping means 2
The function (mode) is normally set to the second mode, and when the function of the sound stopping means 2 is in the second mode, the function changing means 3
The function of the sound stopping means 2 is changed from the second mode to the first mode. When the function of the sound stopping means 2 is in the first mode, the function changing means 3 changes the function of the sound stopping means 2 from the first mode to the second mode when the function is driven. To be changed to

The display means 4 displays whether the function (mode) of the sound stopping means 2 is set to the first mode or the second mode. More specifically, the display means 4 includes, for example, an indicator light as described later.
(Dedicated caution light), function (mode) of sound stop means 2
When the function is set to the second mode, the indicator light is turned off, for example, and when the function (mode) of the sound stopping means 2 is set to the first mode, the indicator light is turned on or blinks, for example. Has become.

By the way, a switch for stopping the area sound can be used as the sound stopping means 2. In the present invention, the sound stopping means 2 is provided with the first mode and the second mode. As the switch for stopping the area sound, only one switch for stopping the area sound is sufficient.

In the present invention, a predetermined key (for example, a maintenance mode key) can be used as the function changing means 3.

That is, according to the present invention, the switch for stopping the area sound can be normally made to function as a switch having, for example, the second mode function. In this case, for example, even if a general user operates this switch to set the district sound devices Ba, Bb to the sound stop state, the local acoustic devices Ba, Bb are not affected by the input of a predetermined signal from the terminal. The ringing stop state is automatically released, and the district sound device can be set to the ringing enabled state again. As described above, this one switch is set to the second mode (re-ringing mode).
Can be used as

When, for example, a maintenance / inspection operator presses a predetermined key (for example, a maintenance mode key) as the function changing means 3 for performing maintenance, the switch for stopping the area sound is switched to a switch having a first mode function. Switch to the function as. In other words, this switch can function as a switch of the first mode (complete sound stop system), and when the maintenance / inspection operator operates the switch for stopping the local sound, the local sound devices Ba and Bb are in the sound stop state. Unless this switch is operated again (for example, unless this switch is returned to the sound stop release side), the district sound devices Ba and Bb can be held in the sound stop state. That is, when performing maintenance, this switch is operated (turned on), and the maintenance of the district sound device can be maintained in a sound stop state during maintenance.

As can be seen from this, in the present invention,
The function of both the above-described district sound stop switch and the collective sound stop switch can be switched and selected by one district sound stop switch. Therefore, it is not necessary to provide the receiver 100 with a collective sound stop switch as a mechanical lock-type switch separately from the regional sound stop switch, and the configuration of the receiver 100 can be kept compact.

That is, one switch for stopping the area sound is a touch type LC, as described later.
It can be displayed on the D screen. In addition, the predetermined key (maintenance mode key) can also be displayed on the touch-type LCD screen, so that the receiver has both the functions of the above-mentioned area sound stop switch and the collective sound stop switch. In this case, it is not necessary to increase the number of switches (lock switches).

When the predetermined key (maintenance mode key) as the function changing means 3 is provided at a place (such as on an LCD screen) where the general user can easily operate the predetermined key (maintenance mode key), When the mode is switched by pressing the (maintenance mode key), in order to prevent such a mode switching process from being performed indiscriminately by a general user, it is better to input a password, for example.

In the second mode, various conditions can be considered as the predetermined conditions on the assumption that a predetermined signal is input from the terminal. For example, as a predetermined condition, when a predetermined signal is input from a certain terminal after the local sound devices Ba and Bb have stopped ringing and a predetermined time is counted from this time, the condition is set as a first condition. ) Can be used to release the ringing stop state.

Alternatively, as a predetermined condition, after the sound is stopped, a predetermined signal is input from a certain terminal (first report), and further, a predetermined signal is input from a terminal different from the terminal.
As a condition (second condition) that there is a (second report), a device that releases the ringing stop state may be used.

Alternatively, as a predetermined condition, after a certain signal is input (first report) from a certain terminal after the sound is stopped and a predetermined time is counted from this time, or the predetermined time is counted. Even before the input of the predetermined signal from a terminal different from the terminal that has output the predetermined signal from which the timing of the predetermined time is started (second report). As the (condition), one that releases the ringing stop state can also be used.

Alternatively, as a predetermined condition, when a predetermined signal is input (first report) from a certain terminal after the sound is stopped, the switch for stopping the area sound is operated again. As the (fourth condition), one that releases the ringing stop state can also be used.

As described above, in the second mode, for example, a general user or a worker operates a switch for stopping the area sound at the time of work or the like, and after the work is completed, the switch is kept in a sound stop state. Even in the case of forgetting to return (even in the case of forgetting to re-operate the switch (second time) and canceling the stop release), the sound is stopped under any one of the above first to fourth conditions. By performing automatic release, 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.

In the following, it is assumed that the first condition is used as the predetermined condition for convenience of explanation.

In the monitoring control system having the configuration shown in FIG. 1, for example, the detector D installed in the monitoring area Aa
a1 to Dan, one of the transmitters Pa issues an alert,
When a predetermined signal input from any of the terminals of the sensors Da1 to Dan and the transmitter Pa is detected in the receiver 100, the sound drive means 1 of the receiver 100 sets the district sound device B
output an operation signal to the local sound device B in the monitoring area Aa
Ring a. Further, after outputting an operation signal to the district sound device Ba and sounding the district sound device Ba in the monitoring area Aa, for example, outputting an operation signal to the district sound device Bb to sound the district sound device Bb in the monitoring area Ab. It is also possible to perform such control as to cause the above.

On the other hand, in the receiver 100, when it is desired to set the district sound devices Ba and Bb to the sound stop state, the operator only has to operate the sound stop means 2 (switch for stopping the area sound) of the receiver 100.

Prior to setting the local sound devices Ba and Bb to the sound stop state, the operator sets the switch for stopping the local sound to a desired one of the first mode and the second mode. Can be. That is, the function (mode) of the sound stopping means 2, that is, the switch for stopping the area sound, is displayed on the display means 4 in the first mode and the second mode.
Which mode is set is displayed, and when the current mode is the desired mode, the operator operates the switch for stopping the area sound in this state, so that the desired mode is set. Can be stopped. On the other hand, when the current mode is not the desired mode, the operator operates a predetermined key (maintenance mode) as the function changing unit 3 so that
By changing the mode to a desired mode and then operating a switch for stopping the area sound, the sound can be stopped in the desired mode.

As described above, when the switch for stopping the area sound is operated and the sound stop means 2 is driven, the sound stop means 2 stops the sound of the area sound devices Ba, Bb in all the monitored areas Aa, Ab, for example. When the switch for stopping the area sound is set to the second mode, the stop releasing means 5 sets the predetermined condition (first condition) as a predetermined condition (first condition).
Sensors Da1 to Dan, Db1 to Dbm, transmitter Pa,
Any terminal of Pb issues an alarm (for example, the sensor Db1 emits an alarm), and when a predetermined signal (first report) is input to the receiver 100 from the terminal that issued the alarm (the sensor Db1), the time is counted. When the predetermined time is measured by the means 6, the local sound device 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). That is, in this case, when the predetermined time is counted by the time counting means 6, the sound stop state is automatically released.

When the local sound switch is set to the first mode, the local sound device is kept in the sound stop state, and unless the switch is operated again (for example, when the switch is stopped). Unless it is returned to the release side), the sound stop state of the district sound device is maintained. That is, in this case, when performing maintenance, the district sound stop switch is operated (turned on) to maintain the district sound device in a sound stop state during maintenance. For example, when the switch is operated (turned on) and the local acoustic devices Ba and Bb are in a sound-stopping state, unless the switch itself is operated (turned off) again, it is determined based on the input of a predetermined signal from a sensor or a transmitter. The sound stop state is not automatically canceled.

FIG. 2 is a diagram showing a specific example of the configuration of the monitoring control system shown in FIG. 1. In the example shown in FIG.
Ab detectors Da1 to Dan, transmitter Pa, detector Db
1 to Dbm and the transmitter Pb are connected to the receiver 100 via one transmission line 51. In addition, the monitoring area Aa,
The local acoustic devices Ba and Bb of 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.

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 and control system of FIG. 2 is configured as a fire alarm facility, the sensors 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. 2, 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 exceeding the predetermined threshold level is output from the sensor Da1 when the address polling of the sensor Da1 is performed, 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, so-called fire alarms which output a fire signal as a predetermined signal by manual operation such as breaking a transparent cover and pressing a button are used.

The local sound devices Ba and Bb are sound devices for notifying a fire such as a bell or a buzzer, and 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.

Further, in the monitoring and control system of FIG.

FIG. 3 is a diagram showing an example of the operation / display unit 24 of the receiver 100. In the example of FIG.
Is composed of an operation unit 31 and a display unit 33. Here, the operation unit 31 and the display unit 33 can be realized by, for example, an operation panel arranged on the surface of the housing of the receiver 100. FIG. 4 is a diagram showing an example of the operation panel.
In the example of FIG. 4, the operation panel includes sensors Da1 to Da.

It comprises a district display section 41 such as a 7-segment LED for displaying floors and lines), a liquid crystal display section 42 of a touch panel type having a screen display function and an operation input function, and various operation switches and indicator lights such as LEDs. A main operation display section 43;
A main sound device 44 that emits an alarm sound and the like, and a printer unit 45 are provided.

FIG. 5 shows an LCD displayed on the liquid crystal display section 42.
FIG. 6 is a diagram illustrating a display example of a screen. In the example of FIG. 5, 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", a "maintenance mode key" and the like are displayed.
In the example, the LCD screen is of a touch panel type, and 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 local sound stop switch is provided as a switch corresponding to the sound stop means 2 of the present invention. In this case, the district sound stop switch is normally set to the second mode function, and the operator
"District sound stop switch" displayed on the LCD screen
By touching the location, the district sound devices Ba and Bb can be set to the sound stop state in the second mode. Further, the operator can switch the function of the district sound stop switch from the second mode to the first mode by touching the location of the “maintenance mode key” displayed on the LCD screen. And in this case, the operator
"District sound stop switch" displayed on the LCD screen
By touching the location, the district sound devices Ba and Bb can be set to the ringing stop state in the first mode.

The function of the district sound stop switch is the first
In order to switch from the mode to the second mode again, the operator only needs to touch the "maintenance mode key" again.

In the example of FIG. 5, the local sound stop switch and the maintenance mode key are realized as a switch mechanism (non-locking type switch mechanism) of the touch panel on the LCD screen. Any switches can be used for keys and the like.
For example, a mechanical switch mechanism can be used.

More specifically, when a mechanical switch is used for the district sound stop switch or the maintenance mode key, if the switch is a non-lock type switch, the state can be easily determined by a signal when the switch is operated. Can be changed. 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, a maintenance mode key, or the like.

However, in order to make the configuration of the receiver 100 more compact, the local sound stop switch and the maintenance mode key are realized as a switch mechanism (non-locking switch mechanism) of the touch panel on the LCD screen. Is good.

As described above, in the configuration example of FIG. 3, the operation unit 31 can be provided with the main sound stop switch, the district sound stop switch, the maintenance mode key, and the recovery switch. Further, the display unit 33 can be provided with a switch warning light, a fire indicator light, a district indicator light, a district sound stop light, and the like.

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 the operation can be performed by a general user.

When the monitoring control system has a configuration as shown in FIG. 2, the ringing driving means 1 includes the first transmission control unit 26, the CPU 21, the second transmission control The sound stop means 2 is realized by the local sound stop switch, the CPU 21, the second transmission control means 27, and the function changing means 3
Is realized by the maintenance mode key, the CPU 21, and 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. The timer 6 is, for example, a CPU 2
1 is realized by a timer built in the device.

That is, when the sound stop switch 2 is operated (turned on), the sound stopping means 2
The sound stop state is held and set in a memory such as 23, and the sound stop control is performed by the CPU 21 so that the operation signal is not output from the receiver 100 to the local acoustic devices Ba and Bb. That is, the CPU 21
When the sound stop state is set and held in a memory such as the RAM 23, the operation signal is not supplied to the local sound device, thereby realizing the sound stop.

Note that the sound stop means 2 operates when the local sound stop switch is operated to hold and set the sound stop state in a memory such as the RAM 23, and further determines whether the sound stop state is in the second mode. Mode information indicating whether the mode is the first mode can be retained and set in a memory such as the RAM 23 so as to be identifiable.

The stop releasing means 5 determines whether the sound stop state of the local sound devices Ba and Bb is in the second mode when a predetermined signal is input from the terminal of the sensor or the transmitter. Depending on the mode (by referring to the mode information stored and set in the memory such as the RAM 23), the CPU 2 controls to release the ringing stop state.
1 to be implemented.

Here, when the local sound stop switch is a non-lock type switch mechanism, when the non-lock type switch is turned on, the sound stop set when the switch is actually turned on is set. The state is, for example, RAM2
3 (the non-locking type switch is turned off immediately after being turned on). Therefore, the stop release means 5 does not actually turn off the switch itself, but the RAM 23 or the like. The ringing stop state held in the memory is released and the ringing is enabled.

It should be noted that not only the non-locking type switch but also the locking type switch can be used for the local sound devices Ba and 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.

Similarly, when the maintenance mode key is operated, the function changing means 3 switches the mode by switching (updating) the mode information currently held in the memory such as the RAM 23. Can be. That is, when the maintenance mode key is a non-lock type, when the non-lock type maintenance mode key is turned on, the mode information currently held in the memory such as the RAM 23 is rewritten, Above, the mode is retained.

It is to be noted that, even if the switch is not only of the non-lock type but also of the lock type, the local acoustic 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 will be described. First, when the sound-enabled state is set in a memory such as the RAM 23, the district sound devices Ba and Bb in all the monitoring areas Aa and Ab are in the sound-enabled state. At this time, for example, the detector D in the monitoring area Aa
When a predetermined signal (fire signal) is input from a1, the receiver 1
00 of the second transmission control unit 2
7 outputs an operation signal to the district sound device Ba of the monitoring area Aa. Thereby, the district sound device Ba sounds. At this time, or after that, the CPU 21 of the receiver 100 further outputs an operation signal from the second transmission control unit 27 to the local sound device Bb in the monitoring area Ab, and also sounds the local sound device Bb. It can also be done.

On the other hand, when the district sound stop switch is turned on, the sound stop state is set and held in a memory such as the RAM 23. Then, the operation signals are not sent to the local sound devices Ba and Bb in all the monitoring areas Aa and Ab, and the local sound devices Ba and Bb enter 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.

When, for example, the second mode is set and held as mode information in a memory such as the RAM 23 when the area sound stop switch is turned on, the area of all the monitoring areas Aa and Ab is set. Sound equipment Ba, B
b is held in the sound stop state in the second mode, and the detectors Da1 to Dan, Db1 to Db1 of the monitoring areas Aa and Ab are maintained.
bm, for example, a predetermined signal from Da1
(Fire signal) input (1st report)
When a timer built in U21 measures a predetermined time, the CPU 21 cancels the sound stop state stored in the memory such as the RAM 23 and sets the sound to a sound enabled state. 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.

When the maintenance mode key is turned on while the second mode is set and held as mode information in a memory such as the RAM 23, the mode information held in the memory such as the RAM 23 becomes: The mode is switched from the second mode to the first mode, and the first mode is
The data is held in the memory until the maintenance mode key is turned on again.

When the local sound stop switch is turned on, for example, the first mode is set and held as mode information in a memory such as the RAM 23.
District sound equipment Ba, Bb in all monitored areas Aa, Ab
Is held in a ringing stop state by the first mode, and the CP
U21 does not release the ringing stop state held in the memory such as the RAM 23 (that is, does not set the ringing enabled state) unless the district sound stop switch is operated again.

As described above, when the district sound stop switch initially has the function of the second mode, for example, a predetermined key (for example, a key provided on the operation panel for the maintenance / inspection operator to perform maintenance). For example, when the maintenance mode key is pressed, the district sound stop switch is switched to the function as the switch of the first mode. When the maintenance and inspection worker operates the district sound stop switch, the district sound devices Ba and B are activated.
b is kept in a sound stop state, and the sound stop state of the district sound devices Ba and Bb is kept unless the district sound stop switch is operated again.

In the configuration example of FIG. 2, the sensors Da1 to Da1
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. 6 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.

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. 7 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. 8 (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. 2, but in the example of FIG. 6, 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 detectors Da1 to Dan connected to the device detects a predetermined event (for example, a fire) and issues an alarm (turns on), or the transmitter Pa operates as shown in FIG. 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.

When the transmitter Pa is operated as shown in FIG. 8 (b) to generate an alarm (turned on), the potential between the L and C lines is obtained.
(24V) drops, and furthermore, the potential (24V) of the response line 55 also drops, whereby the receiver 100
When the impedance between the L and C lines becomes low and the potential of the response line 55 drops, the transmitter Pa
It can be determined that the operation has been performed 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.

As described above, 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. 2 or FIG. 6, but at least the sound stopping means 2, the function changing means 3, and the stop releasing means 5 2 and 6 as long as the function described above is provided, an arbitrary configuration can be adopted.

For example, the configuration shown in FIG. 6 is further modified to provide a P-type receiver 100 with the prior application of the present applicant (Japanese Patent Application No. 8-3549).
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, when the sound is stopped by the sound stopping means 2, for example, when the predetermined signal is input from the terminal, the time keeping means 6 (timer) continues the predetermined signal for a predetermined time from this time. On condition that the input has been made (on condition that the input continuation time of the predetermined signal is equal to or longer than a predetermined time), the sound stop state of the district sound device can be released. 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. In other words, the clocking means 6 operates when the predetermined signal has been input (continuously input) and a preset predetermined time has elapsed.
A signal for canceling the ringing stop can be given to the stop canceling means 5 (when the time is up).

In the present invention, the timer 6 (timer) is required when the first condition or the third condition is used as the predetermined condition. That is, when the second condition or the fourth condition is used as the predetermined condition, the timer 6 may not be provided.

In the above example, the local sound stop switch and the maintenance mode key are used to control the local sound stop via the CPU 21. However, when the CPU 21 goes out of control, the local sound stop is performed. In order to avoid being impossible, these switches and keys may be configured to directly control the local sound stop for the local sound devices Ba and Bb.

Further, in the present invention, the display means 4 for displaying the current mode (either the first mode or the second mode) of the ringing stop means 2 is the same as that shown in FIGS. For example, the LCD screen of the liquid crystal display section 42 and / or
Alternatively, a display lamp (for example, an LED) of the main operation display section 43 can be used, and the display means 4 displays mode information held in a memory such as the RAM 23, for example. Then, the operator displays the current mode of the sound stop means 2 on the display means 4, for example, when operating the sound stop means 2, the sound stop means 2 (area sound stop switch) is currently It is possible to easily know which of the first mode and the second mode is set. In addition, district sound system B
When a and Bb are in the sound stop state, the operator can easily know which of the first mode and the second mode the sound stop state is.

Further, 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 example of FIGS. 4 and 5, 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.

When the local sound stop switch is of a non-lock type, the LCD screen of the liquid crystal display section 42 and / or
Or, the indicator light (for example, LED) of the main operation display unit 43 includes:
Rather than displaying the state of the switch itself, for example, a sound-stopping state, a sound-enabled state, and the like, which are stored in a memory such as the RAM 23, are displayed accurately. Thus, 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 a 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 as described above, 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, and the sound stop state of the sound stop state. 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. .

Also, 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 blinking state to a lighting state). That is, the display means displays not only a state (sound-enabled state or sound-stopped state) for the local sound devices Ba and Bb, but also a state in which a predetermined signal is input from the sensor when the sound is stopped. It may be. When such a display is made, the operator can immediately and accurately know that a predetermined signal has been input from the terminal when the sound is stopped.

As described above, in the ringing enabled state, the ringing stopped state, or the state in which the predetermined signal is input from the sensor in the ringing stopped state, for example, the LCD screen of the liquid crystal display unit 42 and / or the main unit can be identified. By displaying on the indicator lamp (for example, LED) of the operation display unit 43, it is possible to clearly inform the operator of the state of the local sound devices Ba and Bb.

In the above example, only one switch (district sound stop switch) is provided as the ringing stop means 2, that is, a switch for stopping the local sound, and this switch is set to the second mode. The first condition, the second condition, the third condition, or the fourth condition is used as the predetermined condition of the re-sound in the case where the sound is stopped. , The second condition, the third condition, and the fourth condition may be provided as a predetermined condition for re-sounding.

For example, the sound stop means 2 includes a first area sound stop switch that automatically cancels the sound stop state in the second mode under the first condition, and a sound stop state in the second mode. The two types of switches, the second area sound stop switch which is automatically released under the condition 2 and the receiver 10
0 can also be provided.

In this case, the first and second district sound stop switches normally function as, for example, switches in the second mode. For example, when a general user operates the first district sound stop switch, the first and second district sound stop switches are operated. When the sound device is set to the sound stop state, the sound stop state of the district sound device is automatically released under the first condition, and the district sound device can be set to the sound ready state again. When the second area sound stop switch is operated to put the area sound apparatus in the sound stop state, the sound stop state of the area sound apparatus is automatically canceled under the second condition, and the area sound apparatus can be sounded again. Can be

Then, for example, when a maintenance / inspection operator presses a predetermined key (for example, a maintenance mode key) provided on the operation panel for performing maintenance, the first and second district sound stop switches are activated. Switch to the function of the mode switch. Therefore, when the maintenance / inspection operator operates the first or second district sound stop switch, the district sound device is kept in a sound stop state, and unless the first or second district sound stop switch is operated again, the district sound is stopped. The sound stop state of the device is maintained.

In the above-described example, the first area sound stop switch and the second area sound stop switch are separate switches from each other, but they may be configured as one common switch. it can. In this case, the receiver 100 must be further provided with a selection means for selecting whether the common switch is used as the first regional sound stop switch or the second regional sound stop switch. The first area sound stop switch and the second area sound stop switch can be switched and set by the selection means when necessary, and used. In this case, the selection means may be, for example, a CPU
21 by switching and selecting the operation mode. That is, if the operation mode for the input from the common switch component is set to the “first district acoustic stop switch” by software, this switch component can function as the first district acoustic stop switch, If the operation mode for the input from the common switch component is set to the "second area acoustic stop switch" by software, this switch component is set to the second
Function as a local sound stop switch.

In the above example, the function changing means 3
When a predetermined key (for example, a maintenance mode key) is operated to change the function of the ringing stop means 2 from the second mode to the first mode, a certain period of time from the time when the first mode is set is set. When the operation of the receiver 100 is not performed in the meantime, the function of the sound stopping means 2 may be automatically changed to the second mode.

As described above, when the operation of the receiver 100 is not performed for a certain period of time from the time when the first mode is set, the function of the sound stopping means 2 is automatically changed to the second mode. In this case, the maintenance / inspection operator operates the sound stop means 2 (area sound stop switch) in the first mode to set the sound stop state in the first mode, and then sets the area sound stop switch. Even if the user forgets to return, the ringing stop state is automatically switched from the first mode to the ringing stop state of the second mode after a lapse of a certain period of time, and under a predetermined condition on the assumption that a predetermined signal is input from the terminal. Then, the ringing stop state is released, and the district sound devices Ba and Bb are set to a ringing enabled state. That is, when the receiver 100 receives a predetermined signal (for example, a fire signal), the occurrence of a fire or the like can be notified.

In each of the above-described examples, when the sound stopping means 2 is set to the first mode, the sound stopping means 2
Is driven, the district sound devices Ba and Bb are set to be in a ringing stopped state in which no sound is output (the sound volume is set to 0).
It is also possible to set a sound stop state in which the sound volume of the sounds a and Bb is reduced.

In such a configuration, R
When the first acoustic mode switch is turned on while the first mode is held as mode information in the memory such as the AM 23, the sound is stopped when the local acoustic stop switch is turned on. The sound is not completely stopped, but the sound of the sounds of the district sound devices Ba and Bb is reduced to a sound stopped state. In this case, the sensors Da1 to Dan, Db1 to Db of the monitoring areas Aa and Ab are used.
bm, for example, a predetermined signal from Da1
When there is a fire signal input (1st report), the local sound system B
a and Bb can be sounded at a low volume. As a result, the maintenance and inspection workers, etc.
The work can be performed without being disturbed by the sounds of a and Bb, and the occurrence of abnormalities can be known by the local sound devices Ba and Bb sounding even at a low volume.

When the first mode of the ringing stop means 2 is provided with a function of setting the ringing stop state in which the sound volume of the local sound devices Ba and Bb is reduced, the first mode is set. In the same manner as described above, the sound stop state (the sound stop state in which the sound volume is reduced) can be prevented from being released unless the district sound stop switch is operated again, or the first mode can be set as follows. After the setting, when a certain period of time elapses, the sound stop state (the sound stop state in which the volume is reduced) can be released.

In the above example, the ringing stop state in the first mode is the ringing stop state in which the volume is reduced. However, instead of the first mode, or together with the first mode, the ringing stop state may be changed. The sound stop state in the mode 2 may be a sound stop state in which the volume is reduced.

In each of the above examples, the monitoring control system has two monitoring areas Aa and Ab set therein. In the monitoring area Aa, the sensors Da1 to Dan and the transmitter Pa
And the district sound device Ba is installed, and the monitoring area Ab
Is equipped with the sensors Db1 to Dbm, the transmitter Pb, and the district sound device Bb. However, the number of monitored areas is not limited to two, and may be any number (for example, one , 3
, Etc.), and the number of detectors, transmitters, and local sound devices can be arbitrarily increased or decreased accordingly.

In each example described above, one monitoring area,
For example, Aa is provided with one district sound device, for example, Ba, but a single monitored area may be provided with a plurality of district sound devices.

In the configuration examples shown in FIGS. 2 and 6, it is also possible to connect the local acoustic device to a transmission line or a line via a repeater. Similarly, in the configuration example of FIG. 6, each sensor can be connected to a line via a repeater.

In the configuration example of FIG. 6, when the second condition and the third condition are used as the predetermined conditions in the second mode, a pair of L and C lines, for example,
Potential change between 3a (drop of potential between a pair of L and C lines)
However, it is preferable to be configured to change stepwise according to the number of sensors and transmitters that have issued (turned on).

That is, 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 connected to, for example, the same L and C lines (for example, 53a). In the case where the detectors (for example, Da1 and Da2) are present, in order for the receiver 100 to detect the first report and the second report, the potential change between a pair of L and C lines, for example, the district line 53a ( Drop in potential between a pair of L and C lines)
It is preferable that the configuration be changed stepwise according to the number of detectors (turned on) and transmitters.

For example, the potential drop between a pair of L and C lines when an individual sensor or 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.

Further, in the configuration example of FIG.
In the case where 0 is provided with a district sound stop function and a district sound stop release function (functions of sound stop means 2, function changing means 3, display means 4, stop release means 5, etc.) of the present invention, these functions are implemented, for example, by software. Package (Specifically, C
(An information recording medium such as a D-ROM). That is, a program for realizing the district sound stop function and the district sound stop release function of the present invention (ie,
The program used by the CPU 21 and the like can be provided in a state recorded on a portable information recording medium.

In this case, the receiver 100 is preferably provided with a mechanism for detachably mounting the information recording medium. Further, the information recording medium on which the program or the like is recorded is not limited to a CD-ROM,
An OM, a RAM, a flexible disk, a memory card, or the like may be used. When the information recording medium is mounted on the receiver 100, the program recorded on the information recording medium is installed in a storage device (for example, the RAM 23) of the receiver 100, so that the program is executed to execute the program. It contributes to the construction of a monitoring and control system that realizes the sound stop function and the district sound stop release function.

A program for realizing the above-described test function of the present invention is provided not only in the form of a medium, but also by communication (for example, by a server).
May be provided.

In each of the above examples, it is assumed that the monitoring and control system is, for example, a disaster prevention system (fire alarm system). In this case, the detector is, for example, a fire detector, and the transmitter is, for example, a fire alarm. However, the present invention is not limited to a disaster prevention system, but can be applied to any system such as a crime prevention system. In this case, a security detector, a security alarm, or the like can be used instead of the fire detector or the fire alarm.
