DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disaster prevention monitoring device,
In particular, the present invention relates to a disaster prevention monitoring device having a control function capable of simultaneously controlling the sound of a designated bell when performing bell sound control.

[0002]

2. Description of the Related Art Conventionally, as this kind of disaster prevention monitoring device, a disaster prevention monitoring device disclosed in Japanese Patent Application Laid-Open No. 1-35693 is known. This prior art discloses a technique in which a district bell driven and controlled by a district bell drive circuit is intermittently sounded and an emergency broadcast is performed while the sound of the district bell is suspended.

[0003] In such a disaster prevention monitoring device, since the ringing of the district bell is controlled by a district bell drive circuit provided in the receiver, it can be applied to a small-scale building facility. When a high-rise building facility, for example, a building becomes high-rise, it is necessary to draw a bell wire from a receiver for each line, and the bell wire increases, so that there is a problem that cost is increased and construction is difficult.

Specifically, when a fire detector detects a fire, the district bell rings the bell in the guard area of the fire detector. Bell wire pulled out of the machine increases. on the other hand,
As a disaster prevention monitoring device used for a large-scale building, an intelligent disaster prevention monitoring device is known. In such an intelligent disaster prevention monitoring device, when the bell is to be sounded, the bell is sounded by specifying the address of the bell repeater. For this reason, in a place where the floor is wide, there may be a plurality of guard areas, and when ringing a bell in a plurality of warning areas, the receiver may specify the address of the bell repeater and sequentially transmit commands. Become.

[0005]

However, the bell ringing of such a conventional intelligent disaster prevention monitoring device has the following problems. FIG. 7 is a timing chart in a case where the bell ringing control is sequentially performed on the individual bell repeaters to ring all at once.

(1), (2) and (3) indicate bell repeaters, respectively. When an individual command A is transmitted to each bell repeater (1), (2) and (3), In 1) and (2), and in (2) and (3), the bell is turned on while generating a time lag of t. If the bell ringing timing is shifted for each guard area in this way, people in the building trying to evacuate may give strange feelings, and emergency broadcasting for evacuation guidance during the bell ringing suspension period , There is a problem that it is difficult to take timing.

On the other hand, as shown in FIG. 8, there is also known a method in which a simultaneous ringing command B is transmitted to each of the bell repeaters (1), (2) and (3), and all the bell repeaters sound simultaneously. In this case, there is no time lag between the bell transponders, but the fire will cause bells to sound in areas other than the warning area where bells must be sounded, and the evacuation route There was concern that people would be concentrated, causing secondary disasters, and causing people inside the building to feel uneasy.

The present invention has been made based on such a background, and an object of the present invention is to provide a disaster prevention monitoring device capable of performing synchronized bell ringing only in a necessary guard area even in a large-scale building facility. To provide.

[0009]

In order to achieve this object, the present invention provides at least one bell provided for each guard area when a fire detection signal from a fire detector or the like is received by a receiver. In a disaster prevention monitoring device that performs bell ringing by controlling a plurality of bell repeaters connected to the receiver, the receiver includes an individual synchronization command for the bell repeater in the alert area where the bell is to be ringed, and a command for all the bell repeaters. A ring control unit that transmits both simultaneous synchronization commands is provided.The bell repeater includes a control circuit that turns on or off the bell line switch according to AND conditions of the individual synchronization command and the simultaneous synchronization command for starting or stopping. It is characterized by having.

The control circuit of the bell repeater turns on and off the bell wire based on an on / off control signal obtained by an AND condition of the individual synchronization command and the simultaneous synchronization command to make the bell intermittently sound. It is desirable.

[0011]

According to the present invention, the address of the bell repeater in the guard area where the bell is to be sounded from the receiver is designated, and the individual synchronization command is transmitted in sequence. The bell repeater to which the individual synchronization command has been sent does not perform the bell ringing operation at that time, but is held in a bell ringing allowable state (a flag is set). Next, the receiver transmits a simultaneous synchronization command to all the bell repeaters.

Here, since the bell repeater has a control unit for sounding the bell in response to an AND condition of the individual synchronization command and the simultaneous synchronization command for starting, the individual synchronization command is transmitted prior to the simultaneous synchronization command. Only the bell transponder to which the bell is sent, that is, the bell transponder in the guard area in which the bell is to be sounded, sounds the bell. At the time of the bell stop, the simultaneous stop is similarly performed by the AND condition of the individual synchronous command and the simultaneous synchronous command for stop.

[0013]

FIG. 1 is an overall block diagram showing an embodiment of a disaster prevention monitoring device according to the present invention. In FIG. 1, reference numeral 10 denotes a receiver, and a repeater 14 for a detector, an analog smoke detector 16, an analog heat sensor 18, and a repeater 20 for a bell (20-1, 20-1) are connected to a transmission line 12 drawn from the receiver 10. 20-
2, 20-3). In this embodiment,
Control repeaters other than the bell repeater 20 are not shown because they are not directly related to the present invention.

From the sensor repeater 14, a sensor line 22 is provided.
Is pulled out, and the on / off sensor 24-
1, 24-2, 24-3,... And a transmitter 26 for transmitting a fire signal by a push button operation. Also, the bell wire 28 (28-1, 2-1) from the bell repeater 20 is used.
8-2, 28-3), district bell 30 (30-1, 30)
-2, 30-3) are connected.

On the other hand, the receiver 10 is provided with a control unit 32 using a CPU.
4. An operation unit 36 and a sounding unit 38 for outputting an alarm or a voice message are provided. The control unit 32 of the receiver 10 includes C
A call control unit 3 realized by PU program control;
An interrupt processing unit 4 and a sound control unit 5 are provided. Correspondingly, the terminal is provided with a call responding unit 6, an interrupt transmitting unit 7, and a terminal control unit 8 for performing terminal driving and terminal testing, as typically shown by the sensor repeater 14.

The call control section 3 of the receiver 10 sets a series of terminal addresses for each terminal. For example, 127 addresses 1 to 127 are used. Receiver 10
During normal polling for collecting terminal information, the call control unit 3 uses a call signal including a terminal address and a call command to sequentially call terminals at regular intervals and transmit terminal information as a response.

When controlling the terminal, the call control unit 3 transmits a control signal specifying a terminal address, and simultaneously inserts a polling call signal between the control signals and transmits the control signal. Here, as the control signal for the terminal, the address of the sensor repeater 14, the analog smoke detector 16, and the analog heat sensor 18 are sequentially designated, and in addition to the terminal test control signal for sending a test command, the ringing control There is a control command from unit 5 for driving the district bell 30 of the bell repeater 20. This control command will be described in detail with reference to FIGS.

FIG. 2 shows a disaster prevention monitoring device according to the present invention.
It is a wiring diagram of a receiver and the repeater for bells. As shown in FIG. 2, from the receiver 10, the bell repeater 20
A bell line (BB, BBC) 28 to which power for bell ringing is supplied is drawn out in addition to the transmission paths represented by S and SC, and power is supplied to each district bell 30 connected to the bell repeater 20. It is supposed to.

FIG. 3 shows a disaster prevention monitoring device according to the present invention.
FIG. 3 is a circuit diagram of the bell repeater 20. As shown in FIG.
The bell wire 28 is provided with a relay contact 41, which is turned on and off by a relay drive circuit 42. The relay drive circuit 42 is driven by a control circuit 43. In the case of intermittent sounding, a command is sent from the control circuit 43 to the relay drive circuit 42 based on the on / off control signal from the receiver 10, and the relay contact 41 is turned on / off.

The bell repeater 20 further includes an address setting circuit 44 for setting an address, and a transmission / reception circuit 45 for exchanging signals with the receiver 10. In the normal state, the power supplied from the bell wire 28 is controlled so that the relay contact 41 provided in the bell repeater 20 is turned off, so that the district bell 30 does not ring. Next, the bell ringing control operation of the present invention will be described.

FIG. 4 is a flowchart of bell sound control on the receiver side, and FIG. 5 is a flowchart of bell sound control on the bell repeater side. First, the processing on the receiver 10 side shown in FIG. 4 will be described. In step S1, the receiver 10 determines whether or not a fire alarm has been received from a sensor provided in the alert area. If so, in step S2, the receiver 10 specifies the address of the sensor. When the address can be specified, a control command is sent to the corresponding bell repeater 20 in order to control the bell ringing of the alert area by a preset matrix or computer program.

Here, in the present invention, there are an individual synchronization command C and a simultaneous synchronization command D as control commands. The simultaneous synchronization command includes a start simultaneous synchronization command for causing the bell to sound, and a stop simultaneous and synchronization command for stopping the sounded bell. The individual synchronization command C is sent to the bell transponder 20 in the guard area where the fire has occurred and in the vicinity thereof or an evacuation route, that is, the bell area where the bell must be sounded. On the other hand, the simultaneous synchronization command D is transmitted to all the bell repeaters 20.

In step S3, the individual synchronization command C is transmitted to the bell repeater 20 whose address is specified. Next, in step S4, all bell repeaters 20
, A start simultaneous synchronization command D is transmitted. next,
The bell sounding process on the bell repeater side will be described based on the flowchart of FIG.

First, in step S11, it is determined whether an individual synchronization command C has been received. If received, the receiving process is performed in step S12. The reception processing in this case is to set a flag indicating that the reception has been completed,
0 is set to a bell ringing allowable state. Since the simultaneous synchronization command D is transmitted to the all-bell repeater 20 as described above, the reception processing is performed in step S13. Here, the reception processing means to AND the individual synchronization command C and the simultaneous synchronization command D for starting. Next, in step S14, a bell sounding process is performed. That is, the district bell 30 connected to the plurality of bell repeaters 20 specified by the AND condition of the commands C and D.
Only in this case, a command is issued from the control circuit 43 in order to perform simultaneous ringing, the relay drive circuit 42 is operated, and the relay contact 41 is turned on. In this manner, the bell can be sounded only in the necessary guard area.

When the intermittent ringing of the district bell 30 is performed, an individual synchronization command C is transmitted to the bell transponder 20 whose address is specified after a predetermined time, and then all the bell transponders 20 are transmitted. It is sufficient to transmit the stop simultaneous synchronization command D to stop the ringing of the bell and repeat this. Also, by transmitting a simultaneous synchronization command for intermittent ringing, the intermittent ringing of the district bell 30 may be automatically performed by the control circuit 43 of the bell repeater 20.

FIG. 6 is a timing chart in the case of performing simultaneous ringing control by selectively designating only a specific bell repeater. Here, (1), (2), and (3) indicate each bell repeater. In the case of the timing chart of FIG.
Since the individual synchronization command C is transmitted to (1) and (2), even if the simultaneous synchronization command D is transmitted to all of (1), (2), and (3), the individual synchronization command C is transmitted to (1) and (2). District Bell 3
Only 0 sounds at once.

The sound control section provided in the receiver 10 shown in FIG. 1 naturally has the same sound control function as the conventional one shown in FIGS. 7 and 8.

[0028]

As described above, according to the present invention, it is possible to simultaneously ring the bell only in the alert area where the bell needs to ring, so that people in that area can evacuate without discomfort. Becomes Also, in this case, if the bell ringing is performed intermittently, the timing of the emergency broadcast during the bell ringing suspension period can be easily set, and the difficulty of hearing the emergency broadcast due to the delay of the bell ringing can be eliminated. In addition,
The emergency broadcast may be automatically controlled by voice synthesis or performed by an administrator.
