Description

  TECHNICAL FIELD The present invention relates to a disaster prevention monitoring system, and more particularly, to a system that notifies a fire occurrence by a district sound device.

  In the fire alarm system, receivers are installed in disaster prevention centers and management rooms, etc., and a fire signal from a detector installed in each room is detected by the receiver to notify the manager and installed in the building. You can ring the area sound device (bell) to alert you of the danger and urge condemnation and initial fire extinguishing. In such a fire alarm system, as shown in Patent Document 1, it is obliged to inspect every predetermined period. The inspection items of the fire alarm system include the ringing test of the district audio system. The ringing test of the district audio equipment confirms that the district audio equipment rings at a predetermined sound pressure when the push button of the transmitter is operated or the sensor is activated. Usually, the sound test of the district audio system is performed by, for example, one worker operating the push button of the transmitter to confirm the sound of the district audio system, and another worker operating the receiver to stop the ringing. I am doing a lot of work.

Japanese Patent No. 3661474

In the sounding test of the district audio system, it is necessary to perform a test to confirm whether the sounding sounds at the same volume as the loud sound that sounds when an actual fire occurs.
However, even when performing maintenance and inspection, if the district audio system is rung at the same volume as when a fire actually occurred, a loud bell would suddenly ring, which would be a major psychological issue for the surrounding residents. May impose a physical burden. In addition, a worker who performs maintenance and inspection may hear a loud bell sound at each inspection, which may be a psychological burden.

  In view of the above problems, it is an object of the present invention to provide a disaster prevention monitoring system that can reduce the psychological burden on surrounding residents and workers when performing a ring test.

In order to solve the above problems, a disaster prevention monitoring system according to an aspect of the present invention is a disaster prevention monitoring system that sounds a district sound, and sounds when an actual fire occurs in a period when the district sound is sounded. Including a period of driving at a first voltage that generates a sound volume at that time and a period of driving at a second voltage that is a voltage lower than the first voltage, and after driving at the second voltage, It is characterized by having a ringing control unit for ringing the district sound by continuing the process of repeating driving with one voltage until an operation signal instructing to stop ringing is input .

  According to the present invention, the driving voltage of the district audio device when performing the ringing test is driven by the first voltage that generates the volume when ringing when an actual fire occurs, and the driving voltage is lower than the first voltage. A period of driving with a second voltage which is a low voltage is included. As a result, it is possible to reduce the mental burden on the workers and the surrounding residents compared with the case where the ring sound ringing test is performed only during the period when the sound is loud.

It is a block diagram which shows the outline of the disaster prevention monitoring system which concerns on the 1st Embodiment of this invention. It is a flowchart which shows the operation procedure at the time of performing a ringing test of a district sound apparatus in the disaster prevention monitoring system which concerns on the 1st Embodiment of this invention. It is a wave form diagram of an example of the drive voltage of the district sound device in the test mode in the disaster prevention monitoring system according to the first embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an outline of a disaster prevention monitoring system 1 according to the first embodiment of the present invention.

  As shown in FIG. 1, the disaster prevention monitoring system 1 according to the first embodiment of the present invention includes a receiver 11 installed in a disaster prevention center or a management room, and a detector 12a installed in each room of a building. , 12b, 12c and transmitters 13a, 13b, and district acoustic devices 14a, 14b, 14c installed in various places of the fire protection target building. The number of detectors, transmitters, and district audio devices installed is arbitrary.

  The receiver 11 includes a control unit 21, a display unit 22, an operation unit 23, a reception unit 24, a main sound output unit 25, a district sound drive unit 26, and a district sound drive voltage setting unit 27. There is. The control unit 21 controls the overall operation of the receiver 11. The display unit 22 displays various inputs and warnings. The operation unit 23 inputs various operations. The receiving unit 24 receives the fire signal from the sensors 12a, 12b, 12c and the transmitters 13a, 13b. The main sound output unit 25 notifies the occurrence of fire by a warning buzzer. The district sound drive unit 26 drives the sounds of the district sound devices 14a, 14b, and 14c. The district sound drive voltage setting unit 27 sets the drive voltage of the district sound devices 14 a, 14 b, 14 c output from the district sound drive unit 26. The district sound drive unit 26 and the district sound drive voltage setting unit 27 function as the ringing control unit 30. When performing the operation test of the district audio devices 14a, 14b, 14c, the ringing control unit 30 drives the district audio devices 14a, 14b, 14c at the voltage V1 (first voltage) and a voltage lower than the voltage V1. The driving voltage to the district audio devices 14a, 14b, 14c is controlled so as to include the period for driving the district audio devices 14a, 14b, 14c at the voltage V2 (second voltage).

  The detectors 12a, 12b, 12c detect the occurrence of fire. The detectors 12a, 12b, 12c include a heat detector, a smoke detector, and the like. The transmitters 13a and 13b manually transmit a fire signal when a person discovers a fire. A plurality of sensors 12a, 12b, 12c and transmitters 13a, 13b can be connected to the sensing lines 31a and 31b derived from the receiver 24. Although only one sensing line 31a and 31b is shown here, a plurality of sensing lines 31a and 31b can be provided.

  The district audio devices 14a, 14b, 14c are bells that are sounded when a fire occurs and inform people in the vicinity of the fire. A plurality of district acoustic devices 14a, 14b, 14c can be connected to the bell lines 32a and 32b led from the district acoustic drive unit 26.

  In the disaster prevention monitoring system 1 described above, when smoke or heat is detected by the detectors 12a, 12b, 12c, a fire signal is detected by the reception unit 24, and this fire signal is sent to the control unit 21. Similarly, when the push buttons of the transmitters 13 a and 13 b are pressed, the reception unit 24 detects a fire signal and sends the fire signal to the control unit 21.

  When the control unit 21 receives the fire signal from the reception unit 24, the control unit 21 displays the fire information on the display unit 22, activates the main acoustic output unit 25, and causes the warning buzzer to generate a warning sound. Further, when the control unit 21 receives the fire signal, the control unit 21 drives the district sound driving unit 26 to cause the district sound devices 14a, 14b, 14c to ring.

  In the disaster prevention monitoring system 1 according to the first embodiment of the present invention, the receiver 11 is provided with the district acoustic drive voltage setting unit 27. Thereby, the drive voltage to the district audio devices 14a, 14b, 14c can be controlled. The higher the drive voltage to the district audio devices 14a, 14b, 14c, the louder the sound volume of the district audio devices 14a, 14b, 14c. The lower the drive voltage to the district audio devices 14a, 14b, 14c, the smaller the volume of the ringing sound of the district audio devices 14a, 14b, 14c.

  Further, in the disaster prevention monitoring system 1 according to the first embodiment of the present invention, a normal mode and a test mode can be set. When sounding the district audio devices 14a, 14b, 14c, in the normal mode, the drive voltage of the district audio devices 14a, 14b, 14c is the voltage V1. This voltage V1 is a voltage at which the sound pressure level of the ringing sound from the district audio devices 14a, 14b, 14c can maintain a legal sound pressure sufficiently, and at this voltage V1, the district audio devices 14a, 14b, 14c is sounded at a high volume. In the test mode, the driving voltage of the district audio devices 14a, 14b, 14c has a period of the voltage V1 and a period of the voltage V2 lower than the voltage V1. The district audio devices 14a, 14b, and 14c ring at a high volume during the period of the voltage V1 and at a low volume during the period of the voltage V2 as compared with the case of being driven by the voltage V1.

  Next, a case where the ringing test of the district audio device is performed in the disaster prevention monitoring system 1 according to the first embodiment of the present invention will be described. FIG. 2 is a flowchart showing an operation procedure when performing a ringing test of the district audio device. In addition, when performing the ringing test of the district audio device, one of the workers works in front of the receiver 11 and the other one of the workers receives the sensors 12a, 12b, 12c and the transmitters to be tested. Work near the vessels 13a, 13b.

  When performing the ringing test of the district audio device, the worker in front of the receiver 11 operates the operation unit 23 to set the receiver 11 to the test mode (step S1). An operator who is near the sensor 12a, 12b, 12c or the transmitter 13a, 13b to be tested operates by heating or smoking the sensor 12a, 12b, 12c to be tested, or the transmitter 13a. , 13b are pressed (step S2).

  If there is no abnormality in the sound system of the district sound, the fire signal is received by the detector 12a, 12b, 12c to be smoked or heated or the push button of the transmitter 13a, 13b is pressed. The control unit 21 drives the district sound drive unit 26. As a result, the district audio devices 14a, 14b, 14c are sounded.

  FIG. 3 is an example of the drive voltage of the district audio device in the test mode. As shown in FIG. 3, the driving voltage of the district audio devices 14a, 14b, 14c is the voltage V2 in the first period T1, the voltage V1 in the next period T2, and the voltage V2 in the next period T3. At T4, it is set so that the pattern of 0 V is repeated. Therefore, the volume of the ringing sound from the district audio devices 14a, 14b, and 14c decreases in the first period T1, increases in the next period T2, decreases in the next period T3, and becomes silent in the next period T4. Become.

  The worker confirms the ringing sound (step S3). Here, when the worker can confirm the ringing sound (step S3: Yes), the worker determines that the ringing system of the district sound is normal (step S4). If no ringing sound can be confirmed (step S3: No), the worker determines that the ringing system of the district sound is abnormal (step S5). After confirming the presence or absence of an abnormality, the worker in front of the receiver 11 operates the operation unit 23 to stop the ringing of the district audio devices 14a, 14b, 14c (step S6). Then, the worker determines whether or not the tests of all the sensors 12a, 12b, 12c and the transmitters 13a, 13b to be tested have been completed (step S7). If the test of all the detectors 12a, 12b, 12c and the transmitters 13a, 13b to be tested has not been completed (step S7: No), the worker determines the next sensor 12a, 12b, 12c to be tested. Alternatively, the operation is moved to the transmitters 13a and 13b (step S8), and the work is returned to step S2.

  In step S7, if the test of all the sensors 12a, 12b, 12c and transmitters 13a, 13b to be tested has been completed (step S7: Yes), the worker in front of the receiver 11 operates The section 23 is operated to set the receiver 11 to the normal mode (step S9), and the work is completed.

  As described above, in the disaster prevention monitoring system 1 according to the first embodiment of the present invention, in the test mode, the driving voltage of the district audio devices 14a, 14b, and 14c is higher than the voltage V1 during the period when the voltage is V1. There is a period in which the voltage is low V2. As a result, as compared with a case where the district sound ringing test is performed only during the period of ringing at a high volume, the mental burden on the worker and surrounding residents can be reduced during the period of low volume. Further, in the disaster prevention monitoring system 1 according to the first embodiment of the present invention, a silent period is provided for ringing the district acoustic devices 14a, 14b, 14c. The occurrence of the silent period can reduce the mental burden on workers and the surrounding residents.

  In addition, when the district sound devices 14a, 14b, 14c are made to ring at a low volume and then at a high volume, the volume increases after recognizing the ringing of the bell. It is possible to reduce the case where you are surprised by suddenly ringing at a loud volume. In other words, the surrounding residents and workers are surprised and have a great mental burden when they hear a sudden loud sound. On the other hand, if you first hear a low-volume ringing and then hear a high-volume ringing, you will hear the high-volume ringing after your heart is ready with the low-volume ringing. Compared to listening to a loud sound, the mental burden is reduced.

  In addition, even if the local sound devices 14a, 14b, and 14c are sounded so as to include both a period of ringing at a high volume and a period of ringing at a volume lower than that, even if they are continuously ringed for a certain time Since there is a low period, the mental burden on the worker and surrounding residents can be reduced even when the continuous ringing noise is inspected or confirmed.

  In addition, in the example of FIG. 3, the volume of the ringing sound is a pattern of low volume, high volume, low volume, and no sound, but various patterns of the volume of the ringing sound are conceivable. A small volume ringing period may be provided only before a large volume ringing, or a small volume ringing period may be provided only after a large volume ringing. Further, in the example of FIG. 3, the silent period is provided, but the silent period may be omitted.

  Further, in the above-mentioned example, the volume of the ringing sound is changed in two stages in the period of the low volume and the high volume period, but the volume of the ringing sound may be changed in two or more stages. Further, it may be gradually changed from a low volume period to a high volume period or from a high volume period to a low volume period. That is, the district audio drive voltage setting unit 27 may gently change the voltage output to the district audio devices 14a, 14b, and 14c from the voltage V2 to the voltage V1 or from the voltage V1 to the voltage V2.
