Description

The present invention relates to an alarm system for flashing a plurality of optical alarms by synchronous light emission to notify the occurrence of a fire in the event of a fire.

Conventionally, in buildings such as office buildings, store buildings, hospitals, hotels, etc., an automatic fire alarm system has been used as an alarm system for monitoring fires and notifying people in the building of the occurrence of an abnormality when a fire occurs. Is installed.

For example, in a P-type fire receiver installed in a conventional fire alarm system, a fire detector is connected to the detector line drawn from the fire receiver to monitor the fire on a line-by-line basis. When a fire occurs, a sound alarm and/or an indicator light is used to output a fire alarm to building personnel such as a manager, and a district sound device installed on the floor where the fire occurred and on the floor immediately above is also output a district sound alarm. ..

By the way, in recent years, an alarm system has also been proposed that notifies the occurrence of a fire by flashing a white light (flash light) of a high brightness with high visibility together with the sound of the fire (for example, refer to Patent Documents 1 to 3). .. According to such an alarm system, not only the sound but also the flashing of strong light is used to notify the occurrence of a fire, so that, for example, a hearing impaired person can be made to recognize the occurrence of a disaster early and reliably. In addition, a wireless alarm system has been proposed to reduce the labor and cost of wiring (see, for example, Patent Document 4).

In the case of a fire, an optical alarm system sends a sync signal from the optical alarm controller on the fire receiver side to the optical alarm every predetermined period, and the optical alarm that receives the synchronous signal has a predetermined period. Synchronous light emission is performed repeatedly at, and the problem of photosensitivity seizure that causes dazzling can be solved by emitting light at different timings.

In addition, as another example of an alarm system for performing a light alarm, a light alarm control device on the receiver side transmits a synchronization signal to a plurality of light alarms arranged on an evacuation route or the like at predetermined intervals and receives the synchronization signal. A plurality of optical alarms emit light sequentially after different preset delay times have elapsed, and by performing inductive light emission that moves the light emission toward the emergency exit, it is possible to move away from the fire exit location toward the emergency exit. Evacuation can be visually guided.

However, in the case of the conventional warning system that gives a light warning, when the synchronized light emission is performed, the anti-glare effect is high, but the location of the emergency exit is not known unless the evacuation guidance light is searched, and it may take time to evacuate. Remains. In addition, when a plurality of optical alarms are sequentially emitted toward the emergency exit, the direction of the emergency exit can be known, but when the number of optical alarms within the visible range increases, the lights are emitted at different timings. Since the light is seen, it cannot be said that the antiglare effect is high, and there is a possibility that the problem of the photosensitivity attack cannot be solved.

In order to solve this problem, the applicant of the present application has a predetermined special light emission different from the synchronous light emission in a state in which a plurality of optical alarm devices arranged in the evacuation route are controlled by the optical alarm control device to emit the light in synchronization. Has proposed a warning system that controls the vehicle to move in a safe predetermined direction and displays the guidance direction (Japanese Patent Application No. 2015-147290).

According to such an alarm system, the optical alarms arranged in a line in the evacuation route move toward a safe direction while performing synchronous light emission in which all the optical alarms simultaneously emit light in a predetermined cycle at the time of fire. The special light emitted indicates the guiding direction, and while keeping the high anti-glare effect by the synchronized light emission, at the same time, showing the safe evacuation direction enables quick evacuation action without causing confusion.

By the way, in an alarm system that uses a special light that moves in a safe direction to display the guidance direction while performing synchronous light emission of the optical alarm, if the fire location is specified, the special light is emitted. It is controlled so that it moves in the direction away from the fire area, and guidance display in a safe direction is possible.

However, in a P-type fire alarm system that monitors fires on a line-by-line basis, even if a fire signal is received from a fire detector, it can be understood that it is a fire in the caution area where the detector line is pulled out. The fire location within the warning zone is unknown and cannot be controlled to move the special light emission in a safe direction away from the fire location.

In addition, in a P-type fire alarm system that monitors fires on a line-by-line basis, it can be seen that the fire is in the warning area that received a fire signal, but the fire location in the warning area is unknown, and the fire location is unknown. There is a possibility that it is not possible to promptly and appropriately deal with fires such as site confirmation, initial fire extinguishing, and evacuation guidance.

INDUSTRIAL APPLICABILITY The present invention makes it possible to promptly and appropriately carry out fire countermeasures such as site confirmation, initial fire extinguishing, evacuation guidance, etc. by displaying the fire place in a caution area to be monitored by a P-type fire alarm facility that monitors fire for each line.

A control message is transmitted to the optical alarm device 12 by setting the group number of the normal setting and the reverse setting corresponding to each address and the number of groups.

In addition, the control unit 38 of the optical alarm control device 10 receives the fire notification signal corresponding to the warning area where the fire has occurred from the fire receiver 16, and the transmission line that leads to the same warning area where the fire has occurred. When the fire location notification message is received from the optical alarm device 12 connected to 14, the fire address notification message including the fire address Af is transmitted to and transmitted to all the optical alarm devices 12 connected to the same transmission path 14. The unit 42 is instructed to control the transmission of the light emission synchronization signal at a predetermined light emission period Tf.

(Light alarm)
The optical alarm 12 includes a control unit 44, a transmission unit 46, a light emitting unit 48, and a notification reception unit 50, and operates by receiving power supply from the transmission line 14.

In a state in which the alarm device 12 is controlled to emit synchronous light, a specific special light emission different from the synchronous light emission is controlled to move in a predetermined direction to perform guide light emission control to display the guide direction.

As shown in the time chart of FIG. 4, the synchronous light emission control and the special light emission control by the control unit 38 of the optical alarm control device 10 are performed with respect to 12 optical alarm devices 12 with addresses A=1 to 12 set. , A synchronous light emission signal (pulse signal) is transmitted to perform a synchronous light emission a at a cycle T, and while performing the synchronous light emission, for example, the optical alarm device 12 sequentially performs a special light emission b in a direction in which the address increases, and the light The special light emission b temporally moves in the direction in which the address of the alarm device 12 increases, and the direction toward the emergency exit 24 is displayed by the movement of the special light emission b.

If, for example, address A=4 in the middle of the evacuation route 21 becomes a fire place, special light emission b is given in the direction of increasing addresses (rightward in the figure) starting from address A=4 of the fire place. At the same time, the special light emission b is sequentially performed in the direction in which the address decreases (to the left in the drawing), and the guidance direction is displayed by the special light emission b moving toward the safe direction away from the fire place. While keeping the anti-glare effect, by showing the safe evacuation direction at the same time, quick evacuation action is possible without causing confusion.

FIG. 5 is an explanatory diagram showing an optical alarm address, a group number, and a light emission pattern in the guide light emission control when there is no fire place on the evacuation route, and FIG. 6 is a guide light emission control when the fire place is on the evacuation route. FIG. 7 is an explanatory view showing an optical alarm address, a group number, and a light emission pattern in FIG. 7, and FIG. 7 is an explanatory view showing a correspondence table of addresses and group numbers.

The optical alarm control device 10 of FIG. 2 obtains the group number of the light emitting group from the address of the optical alarm 12 arranged on the evacuation route, and controls the guided light emission of the optical alarm 12. Therefore, as shown in FIG. 3, for example, 12 optical alarms 12 arranged on the evacuation route 21 are set with addresses A=1 to 12 so as to increase toward the evacuation direction where the emergency exit 24 is located. There is.

The optical alarm control device 10 is a light emitting group in which optical alarm devices separated from each other by five are set as a member, assuming that a predetermined number of groups G, for example, G=5, from addresses A=1 to 12 of 12 optical alarm devices 12. Group number N is obtained and is preset in each of the optical alarm devices 12 by transmitting a setting message, and when a fire notification signal is received from the fire receiver 16, a synchronous light emission signal is issued for each light emission cycle Tf during a fire. Control to transmit to 12 is performed.

On the other hand, the optical alarm device 12 arranged on the evacuation route 21 receives the setting message transmitted by the optical alarm control device 10 and presets (stores) its own group number. Synchronous light emission signals that are sequentially transmitted are repeatedly counted up to the number of groups G=5 to obtain the number of receptions C, 1 is subtracted from the number of receptions C to generate a light emission group number P, and the light emission group number P When it matches the group number N of No. 1, special light emission is performed. Further, when the light emitting group number P does not match its own group number N, the light alarming device 12 performs synchronous light emission.

The guide light emission control by the special light emission will be described below in detail, depending on whether the evacuation route has a fire place or a fire place.

(Induction light emission control when there is no fire place on the evacuation route)
FIG. 5 is an explanatory diagram showing an optical alarm device address, a group number, and a light emission pattern number in the guide light emission control when there is no fire place on the evacuation route.

As shown in FIG. 5, the 12 optical alarms 12 arranged on the evacuation route 21 in FIG. 3 have an address A, and an address A=1 that increases in the evacuation direction toward the emergency exit 24 (right direction in the figure). ~12 is set. Here, the direction in which the address A increases is the normal direction, and the direction in which the address decreases is the reverse direction.

Even if the light alarm control device 10 receives the fire notification signal, if the fire location is not on the evacuation route 21, assuming that the number of light emitting groups is G, the light alarm device address A is mod (G). Calculation is performed to obtain the value as the group number N.

That is,
N=(A) mod(G) (Equation 1)
Then, the group number N is obtained. The right side of (Equation 1) is known as a remainder calculation which means calculation of a remainder obtained by dividing the address A by the number G of groups.

Here, assuming that the number G of groups is, for example, G=5, since the fourth to the leftmost optical alarm devices 12 have addresses A=1 to 4, the group numbers N=1 to 4 are calculated from (Equation 1). Since the fifth optical alarm 12 from the left end has the address A=5, the group number N=0 is obtained from (Equation 1), and the group numbers N=0 to 4 are repeated as the address increases. Is required.

In this way, the group number obtained from the equation (1) repeatedly increases in the normal direction in which the address of the optical alarm device 12 increases, so this is set as the normally set groove number. The normally set group numbers for the 12 addresses shown in FIG. 3 are as shown in FIG.

In this way, the group number N and the number G of groups calculated based on the addresses A=1 to 12 are transmitted from the optical alarm control device 10 by the setting message designating the address of each optical alarm device 12, and thereby 12 optical alarms are transmitted. It is set for each of the vessels 12.

Subsequently, the optical alarm control device 10 repeats the transmission of the synchronous light emission signal at the light emission cycle Tf, and the optical alarm device 12 which has received the light emission synchronization signal counts the number of times C of reception of the synchronous light emission signal, and the number of reception times C is 1 Is generated to generate a group number P (=C-1), and when the light emission pattern number P does not match its own group number N, synchronous light emission is performed, and when they match, special light emission is performed.

In FIG. 5, a group number N is shown in correspondence with the address A of the optical alarm device 12 shown on the horizontal axis, while the light emission pattern numbers P=0 to 4 changing with time t on the vertical axis. When the group number N of the alarm device 12 does not match the light emission pattern number P, white circles are used for synchronized light emission, and when they are matched, black circles are used for special light emission. For this reason, the special light emission of the black circle sequentially moves toward the emergency exit 24 as time t elapses, and the guide direction 27 is displayed in the direction of the emergency exit 24.

Further, the special light emission of the black circles is performed every four optical alarm devices 12 corresponding to the group number G=5. Therefore, assuming that the light emission cycle T is 2 seconds, for example, every five optical alarm devices 12 are emitted. Induction light emission control can be realized in which movement by special light emission is repeated in a cycle of 10 seconds.

Further, the value of the number G of groups for which the stimulated light emission control is performed can be appropriately changed, and it is also possible to set G=3 or G=6, for example. However, if G=3 or less, the movement amount of the special light emission decreases correspondingly, and it is difficult to understand the guidance display. Therefore, it is desirable to set G=3 or more.

(Induction light emission control when there is a fire place on the evacuation route)
FIG. 6 is an explanatory view showing an optical alarm device address, a group number, and a light emission pattern number in the guide light emission control when there is a fire place on the evacuation route.

As shown in FIG. 6, there is a fire place 25 in the middle of the evacuation route, and the address A of the optical alarm device 12 closest to the fire place 25 is A=7.

In this case, the optical alarm control device 10 sets the address of the optical alarm device 12 at the fire place to the fire address Af=7, and when the optical alarm device address A is equal to or greater than the fire address Af, the optical alarm device address is mod(G). Then, the group number N is obtained from the above value, that is, the above-mentioned (Equation 1).

Here, since the fire place address Af=7, the group numbers N=2, 3, 4, 0, 1, from the above (Equation 1) for the optical alarms 12 having addresses A=7 to 12 higher than that. Calculate 2. In this case, the group number N is a normally set group number because it repeatedly changes in the normal direction (direction of the emergency exit 24) in which the address increases.

Further, when the optical alarm device address A is less than the fire place address Af, the optical alarm control device 10 multiplies the value obtained by mod(G) of the optical alarm device address A by (-1), and further (G-1 ) Is added to obtain the group number N. That is,
N=(A)mod(G).(-1)+(G-1) (Equation 2)
The group number N is calculated according to.

Here, since the fire place address Af=7, the group numbers N=3, 2, 1, 0, 4, from the above (Equation 2) for the optical alarm devices 12 having addresses A=1 to 6 below that. Calculate 3. In this case, the group number N is a group number of the reverse setting because it repeatedly changes so as to increase in the reverse direction (the direction opposite to the emergency exit 24) in which the address decreases.

In this way, the group number N of the normal setting and the reverse setting calculated based on the addresses A=1 to 12 and the fire place address Af=7 is transmitted from the optical alarm control device 10 to a setting message specifying each optical alarm device address. Therefore, each of the 12 optical alarms 12 is set.

Subsequently, the optical alarm control device 10 repeatedly transmits the synchronous light emission signal at the light emission cycle Tf, and the optical alarm device 12 that has received the light emission synchronization signal counts the number of times C of receiving the synchronous light emission signal, and the number of reception times C is 1 Is generated to generate a group number P (=C-1), and when the light emission pattern number P does not match its own group number N, synchronous light emission is performed, and when they match, special light emission is performed.

In FIG. 6, the special light emission of a black circle with the light emission count value P=0 to 4 that changes with time t on the vertical axis indicates that the right side of the fire place 25 has a normal direction in which the address increases with the passage of time t. The guidance direction 27b that sequentially moves toward (the direction of the emergency exit 24) is displayed, while, on the left side of the fire place 25, the guidance direction 27a that sequentially moves in the reverse direction (the direction opposite to the emergency exit 24) in which the address decreases. Is displayed.

(Address and group number correspondence table)
For the optical alarm device 12 having addresses A=1 to 6 located on the left side of the fire place 25 in FIG. 6, the group number of the reverse setting is obtained by the formula (2), but the fire place is near the right end emergency exit 24. In that case, all the group numbers N of the 12 optical alarms 12 are the group numbers of the reverse setting according to the equation (2).

In addition, the twelve optical alarms 12 arranged along the evacuation route select either the group number of the normal setting or the group number of the reverse setting depending on the fire place, and compare the light emission count value with the synchronous light emission or special light emission. It only has to emit light.

Therefore, as shown in FIG. 7, the group number of the normal setting obtained by the equation (1) and the group of the reverse setting obtained by the equation (2) corresponding to the addresses A=1 to 12 of the optical alarm device 12. A correspondence table in which numbers are set is prepared and stored in advance in the memory provided in the control unit 38 of the optical alarm control device 10 of FIG. 2, and the address is assigned to each of the optical alarm devices 12 before the operation of the system is started. Corresponding normal setting and reverse setting group numbers are stored and set in advance in each optical alarm 12 by sending a setting message, and at the time of fire, the group number of normal setting or reverse setting can be selected by sending the fire address. The synchronous light emission and the special light emission can be controlled by simple control such as comparing with the light emission pattern number obtained from the number of times of receiving the synchronous light emission signal.

(Control operation of optical alarm)
FIG. 8 is a flowchart showing the control operation of the optical alarm device of FIG. As shown in FIG. 8, the control unit 44 provided in the optical alarm device 12 of FIG. 2 uses the set telegram transmitted from the optical alarm control device 10 in step S1 to indicate the number of groups G and the correspondence table shown in FIG. The group number of normal setting and reverse setting corresponding to the self address is stored.

Then, when the operation of the alarm system is started, the presence or absence of the fire transfer signal is monitored from the transfer circuit provided in the detector base 15 of the nearby fire detector 18 in step S2, and the fire transfer signal is monitored. When the reception of is detected, the process proceeds to step S3, and the fire location notification message including the self address is transmitted to the optical alarm control device 10.

If the reception of the fire notification signal is not detected in step S2, the process proceeds to step S4 to monitor the reception of the fire address notification message from the optical alarm controller 10. When the reception of the fire address notification message is detected in step S4, the process proceeds to step S5, the fire address Af extracted from the fire address notification message is compared with the self address A, and if the self address A is equal to or greater than the fire address Af, the process proceeds to step S6. , The normal setting group number N is selected. On the other hand, if the self address A is less than the fire address Af, the process proceeds to step S7, and the reverse setting group number N is selected.

Succeedingly, if it is determined in step S8 that the synchronous light emission signal is received, the process proceeds to step S9, and the number of times of reception C is counted. The number of receptions C is set to C=0 in the initial state. Subsequently, the process proceeds to step S10, and a light emission pattern number P (=C-1) is generated as a value obtained by subtracting 1 from the number of times of reception C.

Next, in step S11, it is determined whether or not the light emission pattern number P matches the group number N of the normal setting or the reverse setting selected in step S6 or S7. When it is determined in step S11 that the light emission pattern number P and the group number N match, the process proceeds to step S12 and special light emission is performed. On the other hand, if it is determined in step S11 that the light emission pattern number P and the group number N do not match, the process proceeds to step S13 to perform synchronous light emission.

Subsequently, in step S14, it is determined whether or not the number of times of reception C matches the number of groups G. If they do not match, the process returns to step S8 to prepare for the next light emission synchronization signal. On the other hand, if the number of receptions C matches the number of groups G in step S14, the number of receptions C is initialized to C=0 in step S15, and the process returns to step S8 to prepare for the reception of the next synchronous light emission signal. Similarly, the processes of steps S8 to S15 are repeated.

The light alarm control device 10 sends the minimum address or the maximum address as the fire address Af as the fire address Af when there is no fire place on the evacuation route, and in this case, all the light alarm devices 12 are sent. The self-address A becomes equal to or greater than or less than the fire address Af, and this is discriminated in step S5, and the process proceeds to step S6, where all the optical alarms 12 take out the group number N of the normal setting or the reverse setting, and the special light emission. Is displayed to move in the normal direction or the reverse direction. In this case, the moving direction of the special light emission may be notified from the light alarm control device 10 to the light alarm device 12 of the fire address Af that is the minimum address or the maximum address so that the special light emission is moved in a certain direction such as an emergency exit.

Further, the light alarm control device 10 notifies the light alarm 12 of a predetermined address as a pseudo fire address even when there is no fire place on the evacuation route, so that the light alarm control device 10 moves away from the pseudo fire address. Guidance display control that moves special light emission can be performed.

(Light emission control when the second fire place is detected)
The optical alarm control device 10 receives the first fire location notification message from the optical alarm device 12 and performs the synchronous light emission and the special light emission of the optical alarm device 12 to the same transmission line 14. When the second fire place notification message is received from another connected optical alarm device 12, the first fire address is Af1 and the second fire address is Af2. A control message for instructing to stop the special light emission is transmitted to the optical alarm device 12 at the address located at, and only the synchronous light emission is performed. Accordingly, even if there are two fire places on the evacuation route, it is possible to perform a guidance display that moves the special light emission in a direction away from each fire place.

(Display control of fire place by display device)

If a fire occurs at the fire place 25 in the middle of the evacuation route 21 shown in FIG. 3, the optical alarm control device 10 uses the fire place notification message received from the optical alarm device 12 corresponding to the fire place to set the fire address Af= 7 is detected. Further, assuming that the fire place is the warning area 1F, the optical alarm control device 10 receives from the fire receiver 16 a fire notification signal indicating a fire in the warning area 1F. Therefore, the light alarm control device 10 generates a fire address notification message including the warning area 1F and the fire address Af=7 and transmits it to the display device 100.

The control unit 102 of the display device 100 refers to the fire place display information of FIG. 9 by the warning area 1F and the fire address 1F acquired from the fire address notification message received from the optical alarm control device 10, and refers to the district name “reception room”. It is acquired and displayed on the display unit 106. The display of the fire place by the display unit 106 may be a character display such as "1F reception room", or in addition to this, the section which becomes the reception room in the map showing the floor plane of the warning area is flickered in red or the like. It may be done.

In addition, even when the light alarm control device 10 receives the second fire location notification message, it includes the warning area 1F and the second fire address by the fire notification signal received from the fire receiver 16 at that time. A fire address notification message is generated and transmitted to the display device 100. As a result, the display device 100 similarly displays the second fire place.
