Description

The present invention relates to an acoustic alarm stop function of a sub-receiver.

Buildings that meet the prescribed standards are obliged to install an automatic fire alarm system as a fire prevention target. The fire receiver is installed in the disaster prevention center or control room of the building to be monitored, and centrally monitors the operation of the fire detectors installed in various places. Sounds to output a fire alarm. If there are multiple disaster prevention centers and management rooms, or if the manager's break room is in a different location, the fire monitoring status can be checked immediately even in locations other than the location where such a fire receiver is installed. A sub-receiver may be installed in.
The sub-receiver is provided with a display function unit and a fire alarm sound output unit (alarm sound unit) indicating a fire occurrence location equivalent to that of the fire receiver. In addition, it is equipped with an acoustic stop switch that stops the sound of the receiver after confirming the fire alarm, and a switch that displays the acoustic stop state of the sub receiver when the acoustic stop switch is turned on (pushing operation). It is equipped with a light or an acoustic stop light.

Conventionally, the acoustic stop function of the sub-receiver is that in the case of the sub-receiver for P-type system (hereinafter referred to as P-type sub-receiver), the fire receiver that receives the input of the fire signal (short-circuit signal) from the fire detector fires. When an alarm is output, a transfer output signal for controlling the acoustic output of the sub-receiver is transmitted from the fire receiver to the sub-receiver (the applied voltage is output). Specifically, as shown in FIG. 6, when the P-type sub-receiver 90a receives the transfer output signal (when it receives the applied voltage), the buzzer BZ is applied with a voltage to output an acoustic alarm. If you want to stop the acoustic alarm output of the sub-receiver 90a, turn on the lock-type acoustic stop switch 970 provided on the front of the panel, and S1 of the receiving circuit (FIG. 6B) will be disconnected for the acoustic alarm. As the output stops, S1 is connected to the circuit section (LD1 etc.) 980 side of the switch caution light, and the switch caution light 980 lights up. If you want to release the acoustic stop state, turn off the lock-type acoustic stop SW to return to the localization.

Therefore, when the acoustic stop SW of the P-type sub-receiver is turned on, for example, when the fire receiver receives the second report, or after the fire receiver operates the acoustic stop SW of the fire receiver and a predetermined time elapses. Even if the fire is detected (in the case of the so-called re-ringing method), even if the fire receiver transmits the transfer output signal to the sub-receiver again (even if the applied voltage is output), the P-type sub-receiver is , The acoustic alarm output could not be performed.

On the other hand, in the case of an R-type system (automatic fire alarm system 110 in FIG. 7), the fire receiver (R-type receiver) 100 and the R-type sub-receiver 90b are connected by a communication line CL such as a shielded twisted pair cable. The two-way communication of various information is performed by the serial communication of RS-485 standard. Specifically, the fire receiver 100 receives an alarm information signal from the repeater 4 or the like, and displays various alarm information on the LCD screen 511 or the indicator lamp (512, 513, 514, 515) of the fire receiver 100. It is displayed, and the alarm sound unit 611 outputs an acoustic alarm. The R-type sub-receiver 90b receives the same type of alarm information signal from the fire receiver 100 by serial communication, displays the same various alarm information on the LCD screen and indicator lamp of the sub-receiver 90b, and also displays the alarm sound. The unit outputs an acoustic alarm (see FIGS. 3, 99a).

When the sub-receiver 90b wants to stop the sound, the soft-lock type sound stop SW provided on the surface of the sub-receiver board is pressed to stop the sound output. At this time, the acoustic stop lamp provided in the vicinity of the acoustic stop SW is turned on (see FIGS. 3, 97b and 98b).
When an alarm information signal is input from the fire receiver 100 during the sound stop, the sub-receiver 90b displays the newly input alarm information on the LCD screen, releases the sound stop state, and outputs the sound again. , Makes the acoustic stop light (98b) blink. In this case, even in the acoustically stopped state, the sub-receiver 90b is released from the stopped state each time it receives a new alarm information signal from the fire receiver 100, so that the sub-receiver 90b is on the fire receiver 100 side. Since it is not necessary to grasp the sound stop state, the function was not particularly provided.

On the other hand, the LCD screen 511 of the R-type fire receiver 100 is a touch panel type and can perform various operations, and the acoustic alarm output of the sub-receiver 90b can be remotely stopped by the setting operation input on the screen. (Alarm stop function). Conventionally, when the sub-receiver alarm stop is set in the R-type fire receiver 100 and the sub-receiver 90b is stopped acoustically, the message display on the LCD screen 511 and the switch caution are performed on the fire receiver 100. A light (one of 512) indicates that the alarm stop of the sub-receiver 90b is being set to alert the administrator and the like (for example, Patent Document 1).
In this case, the fire receiver 100 receives a new alarm information signal, displays an alarm on the LCD screen 511 of the fire receiver 100, outputs an acoustic alarm on the alarm sound unit 99, and outputs an acoustic alarm, and the sub-receiver 90b. Although the alarm information signal is transmitted to, the sub-receiver 90b displays an alarm for a new event, but does not output an acoustic alarm.

Further, the operation unit 97, the display unit 98, and the alarm sound unit 99 are connected to the CPU 91 via an interface (I / F unit) (not shown). The sub-receiver 9 is connected to the fire receiver 10 via the interface (I / F unit) 81 and the communication line CL, and is transmitted from the fire receiver 10 when an event such as a fire or a gas leak occurs. Receives an incoming alarm signal (alarm information signal) (for example, serial communication according to the RS-485 standard).

The display unit 98 is composed of a liquid crystal display (LCD screen) 98a and LED indicator lights (98b, 98c, 98d), and has various functions displayed on the LCD touch panel screen 500 of the fire receiver 10 and various functions similar to alarm data. And, the display is limited to all the alarm data or the information of the predetermined contents. Similar to the LCD touch panel screen 500 of the fire receiver 10, the liquid crystal display (LCD screen) 98a is touch-operated to display a predetermined function, so that the function is selected and the operation screen corresponding to this function is displayed. It may be a possible touch panel type liquid crystal display (LCD screen).

The operation unit 97 scrolls the screen downward when the content displayed on the acoustic stop SW97b for stopping the acoustic output alarm sound of the sub-receiver 9 and the liquid crystal display (LCD screen) 98a does not fit on the screen. The feed SW97d is composed of.

(Sound alarm control and sound alarm stop status display control)
Next, a control for displaying and outputting the sub-receiver acoustic stop state of the present invention and a method for displaying the acoustic stop state will be described.
When the CPU 21 of the fire receiver 10 receives the alarm information signal transmitted from the repeater 4 in response to the notification from the various terminals 3 via the transmission control line TL and the I / F unit 31a, a fire, a gas leak, etc. 8 The display control process of the alarm screen and the alarm window as described above is performed (not shown). Further, the CPU 21 controls the lighting of the LED indicator lamp 50a indicating the representative of the fire when a fire occurs (FIG. 2).
Further, the CPU 21 controls the alarm sound unit 29 to output an acoustic alarm to output an alarm sound from the speaker 29a (and the sound emitting hole).

Further, the CPU 21 of the fire receiver 10 notifies the sub receiver 9 via the interface (I / F) 31b and the serial communication line CL (including the power supply line comprehensively) in response to an event such as a fire or gas leak. Performs communication control for transmitting information signals (RS-485 standard serial communication control).

Next, the CPU 91 of the sub-receiver 9 transmits an alarm information signal (FIG. 8 (c)) corresponding to an event such as a fire or a gas leak transmitted from the fire receiver 10 to the serial communication line CL (comprehensive power supply). (Including line) and receive via interface (I / F) 81 (RS-485 standard serial communication control).
Then, the alarm information data of the received alarm information signal is taken into the RAM 93, and the ROM 92 and the EEPROM 94 display the LCD screen 98a of the display unit 98 according to the control processing program, and the alarm screen similar to the alarm screen and the alarm window as shown in FIG. And the display control process of the alarm window is performed (FIG. 8A). The control processing content of the alarm information displayed on the LCD screen 98a is determined by the command 77 of the transmission format shown in FIG. 8C, and is displayed as character information after the text data is code-converted. The CPU 91 constantly lights and controls the power supply lamp 98c of the display unit 98.
Further, the CPU 91 controls the alarm sound unit 99 to output an acoustic alarm to output an alarm sound from the speaker 99a (and the sound emitting hole).

During the acoustic alarm output, when the acoustic stop SW97b of the operation unit 97 is turned on within 1 second and an acoustic stop signal is input to the CPU 91, the CPU 91 stops the acoustic alarm output control (normal acoustic stop mode). Further, when the acoustic stop SW is pressed and held for, for example, 2 seconds (regardless of whether the acoustic alarm is being output or stopped), the acoustic stop signal is input to the CPU 91, and the CPU 91 timers the input time of the acoustic stop signal for 2 seconds. The sound alarm output control is stopped and the sub-receiver forced sound stop state is set (sub-receiver forced sound stop mode). Then, the CPU 91 controls the communication of the sub-receiver acoustic stop signal to the fire receiver 10 in the same return format as the transmission format of FIG. 8C.

On the other hand, when the fire receiver 10 receives the sub-receiver acoustic stop signal from the sub-receiver 9, the sub-receiver acoustic stop light 55 of the display unit 28 is turned on and controlled. When the fire receiver 10 receives the sub-receiver acoustic stop signal from the sub-receiver 9 at the time of initial setting of the automatic fire alarm system 10, the CPU 21 controls the LCD touch panel 500 to turn off, as shown in FIG. 8 (a). The screen is changed to the alarm screen, the display area of the sub-receiver sound stop display unit 505 set and stored in advance is controlled for display and output, and the text data of "sub-receiver sound stop!" Stored in the ROM 22 is read out. The display output may be controlled.

Lighting control of the sub-receiver acoustic stop light 55 or alarm screen of the LCD touch panel 500 (FIG. 8 (a)) Display control of the sub-receiver acoustic stop display unit 505 (indicator of "sub-receiver acoustic stop!") In order to terminate the operation, the CPU 91 stops the transmission of the sub-receiver acoustic stop signal when the acoustic stop SW97b is turned on within 1 second in the sub-receiver 9 (end of the sub-receiver forced acoustic stop mode).

The example in which the fire receiver of the present invention displays the sub-receiver acoustic stop state has been described above, but the present invention is not limited to this.
For example, in the sub-receiver 9, there is no ON operation input from the acoustic stop SW97b, and the sub-receiver 9 is connected from the fire receiver 10 via the serial communication line CL and the interface (I / F section) 81 of the sub-receiver 9. Is receiving an alarm information signal and is outputting an acoustic alarm by the alarm sound unit 99 of the sub-receiver 9 itself. If the acoustic stop SW97b is further pressed for a long time, the sub-receiver 9 fires. A sub-receiver acoustic stop signal is transmitted to the receiver 10, and the fire receiver 10 displays the LCD touch panel 500 and / or the sub-receiver acoustic stop light 55, so that the fire receiver 10 is installed in a place where the fire receiver 10 is installed. It is easy for the building user to confirm the alarm by the sub-receiver 9 at the place where the sub-receiver 9 is installed and stop the acoustic alarm during the fire alarm when a fire breaks out. I can grasp it.

The fire receiver 10 can individually set the alarm display output and the acoustic alarm output to the sub-receiver 9 by setting the LCD touch panel 500 according to the situation such as maintenance or partial repair. Each output stop can be set.
Further, even when the sub-receiver 9 receives the alarm information signal (alarm output control command) from the fire receiver 10, the acoustic alarm output can be individually set and the acoustic stop can be set by operating the acoustic stop SW97b.

Further, the sub-receiver 9 receives the alarm information signal transmitted from the fire receiver 10 to the sub-receiver 9 and outputs an acoustic alarm. However, the alarm information signal is acoustic to the sub-receiver 9. The information of the alarm output control instruction may be included, or the alarm information signal does not include the information of the acoustic alarm output control instruction in the sub-receiver 9, but includes only the display control command information related to the display. Is also good. That is, when the alarm information signal does not include the information of the acoustic alarm output control instruction but contains only the display control command information related to the display, the sub-receiver 9 is like the P-type sub-receiver of FIG. Equipped with a lock-type acoustic stop SW that shuts off the acoustic alarm output control command signal from the fire receiver easily and completely, and an acoustic output circuit, the control unit of the sub-receiver 9 inputs the display control command information of the alarm information signal. The sound output circuit of the alarm sound unit in the sub-receiver 9 is activated, and the sound cannot be stopped unless the sound stop SW (97b) is turned ON (when the OFF operation is performed, the sound stop state is released and the sound alarm output is restarted. It can also be realized as a configuration).

The present invention can also be applied to equipment such as security equipment in which a central monitoring panel is installed and a sub-receiver (sub-display device) is installed in a remote location.
