Description

  One embodiment of the present invention relates to an optical alarm system that performs optical alarm using light using a flashlight or the like.

  The alarm of the alarm system is generally performed by ringing a bell such as a buzzer. However, in recent years, there has also been proposed an alarm system for notifying the occurrence of a disaster such as a fire using a flashlight or the like having high visibility along with sound (for example, see Patent Documents 1 to 3). According to such an alarm system, since the occurrence of a disaster is notified not only by sound but also by strong light, for example, an effective alarm can be given even to a hearing-impaired person. Hereinafter, such a light alarm is referred to as a light alarm in distinction from conventional display notifications such as LEDs and red lamps.

  For the purpose as described above, the light alarm is performed with white light (flash light) having high luminous intensity, which is pulsed from, for example, a xenon lamp. For this reason, compared with the conventional display notification, for example, a hearing-impaired person can recognize the occurrence of a disaster early and reliably.

  As described above, the light alarm uses high-luminance white light (flash light), but the visibility may be lowered depending on the surrounding environment at the time of light emission. For example, the visibility of the flashlight is different between a bright environment and a dark environment where the light alarm is performed, and the visibility of the flashlight decreases when the area is bright. Moreover, the illumination intensity of the illumination may be different depending on the time zone such as daytime and nighttime, and the visibility of the flashlight is reduced when the illumination is bright. Thus, when the visibility of a light warning falls, the alarm performance of a light warning system may fall.

  One of the objects of the present invention is to ensure visibility of a light alarm in a light alarm system that performs a light alarm.

  According to one aspect of the optical alarm system of the present invention, an optical alarm control device is directly or indirectly connected to a receiving device, and the optical alarm device is connected in parallel to an optical alarm line drawn from the optical alarm control device. A light warning system in which the light warning device performs a light warning based on a control signal output from the light warning control device from the first area and a part illuminated by the light warning device performing a light warning Or lighting based on a lighting device that illuminates the second area where all overlap, and an interlocking transfer signal linked to the control signal transmitted from at least one of the receiving device, the light alarm control device, and the light alarm device A lighting facility management unit that performs dimming control of the facility.

  Since it is configured in this manner, when the light alarm system performs a light alarm, the lighting equipment management unit includes a second region in which a part of or all of the first region illuminated by performing the light alarm overlaps. Dimming control can be performed on the lighting equipment to be illuminated. Therefore, for example, when the lighting equipment management unit makes the lighting equipment darker than the normal brightness, the visibility of the light alarm can be ensured. For this reason, the situation where a light alarm cannot be visually recognized by the environment and time slot | zone which perform a light alarm, for example can be avoided.

Further, in the light alarm system, a plurality of light alarm devices and one or more lighting facilities are provided in a predetermined management area, and the receiving device synchronously controls the plurality of light alarm devices based on the control signal, Dimming control of one or more lighting facilities may be performed based on the interlocking transfer signal.

  If it does in this way, the light alarm of all the light alarm apparatuses in a predetermined management area | region and the dimming control of all the lighting installations can be synchronized. For this reason, the visibility of the light alarm can be ensured at any location within the predetermined management area.

  Furthermore, in the light alarm system, one or more lighting facilities are provided in an adjacent management region adjacent to a predetermined management region, and the lighting facility management unit installs one or more lighting facilities in the adjacent management region based on the interlocking transfer signal. Dimming control may be performed.

  If it does in this way, the lighting installation management part can light-control one or more lighting installations contained in an adjacent management area | region arbitrarily. For this reason, for example, when the illumination in the management area is dimmed dark as described above, the illumination in the adjacent management area adjacent to the management area can be dimmed brightly. Therefore, for example, when evacuating from a management area where a disaster has occurred to an adjacent management area, it is possible to avoid a situation where the adjacent management area is dark and cannot be seen. In addition, it becomes possible to indicate the evacuation direction to the person in the management area by using the difference in brightness between these areas, and the environment in the adjacent management area can be easily confirmed. It is also possible to evacuate quickly in a safe direction.

  Furthermore, the light alarm device measures the illuminance measuring device that measures the illuminance of the light emitting unit that emits light based on the control signal, the region where the light is emitted by emitting light from the light emitting unit, and performs the light alarm, and the illuminance measuring device measures And a control unit that controls the luminous intensity of the light emitting unit based on the illuminance.

  In this way, for example, even if smoke or the like is generated in the light alarm region and it becomes difficult to visually recognize the light alarm, it is possible to ensure the visibility of the light alarm by increasing the light intensity of the light alarm. Become.

  According to one embodiment of the present invention, in an optical alarm system that performs an optical alarm, the visibility of the optical alarm can be ensured regardless of the environment and time zone in which the optical alarm is performed, for example.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a case will be described in which the present invention is applied to an optical alarm system in which a configuration for performing an optical alarm is added to an alarm system that performs an alarm by sound such as a buzzer.

(First embodiment)
FIG. 1 is a diagram showing a configuration of the light alarm system 1. In the optical alarm system 1 illustrated in FIG. 1, the disaster detector 10 is connected in parallel to the disaster detection line DL drawn from the receiving device 50, and a termination resistor (or terminator) is connected to the end of the disaster detection line DL. 2 is connected. Examples of disasters detected by the disaster detector 10 include, but are not limited to, fire and gas leakage. Further, the bell 20 is connected in parallel to the bell line BL drawn from the receiving device 50, and the light alarm control device 30 is connected to the end of the bell line BL. An optical alarm line KL is drawn from the optical alarm control device 30, and an optical alarm device 40 is connected in parallel to the optical alarm line KL, and a terminating resistor (or terminator) 3 is provided at the end of the optical alarm line KL. It is connected. The receiving device 50 is connected to the lighting facility management unit 60 and the general monitoring panel 4 so as to be communicable. The lighting equipment management unit 60 is connected to the lighting equipment 70, the light warning control device 30, and the light warning device 40 in addition to the receiving device 50 described above.

  In FIG. 1, only one disaster detector 10, bell 20, and light alarm device 40 are shown for simplification of illustration and explanation. good. Similarly, only one disaster detection line DL and one light alarm line KL drawn from the receiving device 50 and the light alarm control device 30 are shown, but a configuration in which a plurality of them are drawn as appropriate may be used. Further, similarly, only one lighting facility 70 is illustrated, but the lighting facility management unit 60 may be configured to connect a plurality of lighting facilities 70.

  Here, the disaster detector 10, the bell 20, the light alarm device 40, and the lighting equipment 70 belong to one of the management areas depending on the place where they are installed, and the receiving device 50 has a disaster detection, bell for each management area. It is configured to perform control, light alarm control, lighting control, and the like. The management area is an area set for managing each area such as a room, a hallway, and a lobby in a building. In addition, the light alarm area (first area) illuminated by the light alarm device 40 performing a light alarm and the illumination area (second area) illuminated by the lighting equipment 70 are installed in the management area. Depending on the location of the light alarm device 40 and the lighting facility 70, some or all of them overlap.

  The receiving apparatus 50 includes a power supply circuit 51, a disaster detection circuit 52, a CPU 53, a bell control circuit 54, and an external transfer circuit 55. The power supply circuit 51 supplies power to the disaster detection circuit 52, the CPU 53, the bell control circuit 54, and the external transfer circuit 55 by transforming, rectifying, etc. power from an external power supply (not shown). Based on the disaster detection signal received from the disaster detection circuit 52, the CPU 53 outputs the disaster detection signal to the external transfer circuit 55 and outputs the control signal of the bell 20 to the bell control circuit 54.

  The disaster detection circuit 52 receives a disaster detection signal output from the disaster detector 10 via the disaster detection line DL. When the disaster detection circuit 52 receives a disaster detection signal, the disaster detection circuit 52 transmits the disaster detection signal or a signal based on the disaster detection signal to the CPU 53. Note that when the disaster detector 10 detects a disaster, the configuration in which the disaster detection circuit 52 detects the disaster detection signal and transmits it to the CPU 53 can be the same as that of the prior art. Further, the disaster detection circuit 52 monitors connection failures such as disconnection or short circuit of the disaster detection line DL in the same manner as in the past.

  The bell control circuit 54 monitors connection failures such as disconnection or short circuit of the bell 20 via the bell line BL. Further, when the bell control circuit 54 receives the control signal of the bell 20 from the CPU 53, the bell control circuit 54 reverses (inverts) the polarity of the voltage applied to the bell line BL in order to ring the bell 20. Thereby, the bell 20 connected in parallel to the bell line BL starts ringing. Note that the configuration in which the bell control circuit 54 monitors the connection failure of the bell 20 and the configuration in which the bell 20 rings are the same as in the prior art.

  The external transfer circuit 55 outputs a signal to the lighting equipment management unit 60 and the general monitoring panel 4 based on a signal transmitted from the CPU 53 based on the disaster detection signal. For example, when receiving a disaster detection signal from the CPU 53, the external transfer circuit 55 outputs the disaster detection signal to the general monitoring board 4.

  The integrated monitoring board 4 performs necessary processing based on, for example, a disaster detection signal output from the external transfer circuit 55. The general monitoring board 4 can transmit a report indicating that a disaster has been detected in a predetermined management area, for example, to the management company of the light alarm system 1.

  The lighting equipment management unit 60 controls the dimming of the lighting of one or more lighting equipments 70. For example, when a plurality of lighting facilities 70 are included in the management area, the lighting facility management unit 60 performs dimming control of the plurality of lighting facilities 70 in the management area in synchronization.

  Next, the configuration of the light alarm control device 30, the light alarm device 40, and the lighting equipment management unit 60 will be described in detail with reference to FIGS.

  First, the configuration of the light alarm control device 30 will be described with reference to FIG. The light alarm control device 30 includes a power supply unit 31, a voltage control unit 32, a synchronization pulse output unit 33, and message output units 34-1 to 34-P (P: natural number).

  The power supply unit 31 is supplied with power from the AC power supply, the battery power supply, or the receiving device 50 (via the bell line BL), and receives the voltage control unit 32, the synchronization pulse output unit 33, and the message output units 34-1 to 34-34. Supply power to P. When a control signal is input from the bell line BL, the voltage control unit 32 outputs the control signal to the synchronization pulse output unit 33 and the message output units 341 to 34P. The synchronization pulse output unit 33 outputs a control signal (light warning control signal) synchronized with the input control signal to the light warning device 40. The transfer output units 34-1 to 34-P are provided, for example, corresponding to the above-described management areas, and output various signals to output destinations such as other facilities associated in advance. For example, the transfer output units 34-1 to 34-P manage the linked transfer signal for linking the light alarm control of the light alarm device 40 and the dimming control of the lighting facility 70 with the management of the lighting facility management unit 60. The data is output to a message input unit 63 (described later) associated with (assigned to) the area. In the present embodiment, the transfer output units 34-1 to 34-P also output the interlocked transfer signal to the transfer input unit 63 associated with the adjacent management area adjacent to the management area.

  As shown in FIG. 3, the interlocking signal is a continuous output signal output in conjunction with a light alarm control signal (see FIG. 3A) for emitting a light alarm output from the light alarm control device 30. 3 (b): parallel), or a communication output signal (see FIG. 3 (c): serial) indicating the timing of rising and falling of the light alarm control signal (see FIG. 3 (a)), etc. It is.

  FIG. 4 is a diagram illustrating a configuration of the light alarm device 40. As illustrated in FIG. 4, the light alarm device 40 includes a power supply unit 41, a control unit 42, a light emitting unit 43, and message output units 44-1 to 44-Q (Q: natural number).

  The power supply unit 41 receives a control signal from the light alarm control device 30 or the like. In addition, the power supply unit 41 is supplied with power by a control signal from an AC power supply, a battery power supply, or the light control device 30, and the like, to the control unit 42, the light emitting unit 43, and the message output units 44-1 to 44-Q. Supply power to each. When the control unit 42 receives a light warning control signal input from the light warning control device 30, the control unit 42 controls light emission of the light emitting unit 43 based on the control signal. The light emitting unit 43 performs a light alarm (flash light: light emission of the light emitting unit) based on the light alarm control signal input from the control unit 42. The transfer output units 44-1 to 44-Q are provided, for example, corresponding to the above-described management areas, and output various signals to an output destination such as other equipment associated in advance (allocated). For example, the transfer output units 441 to 44Q may be configured to output the interlocked transfer signal to the lighting equipment management unit 60 together with or instead of the light alarm control device 30.

  Next, the configuration of the lighting equipment management unit 60 will be described with reference to FIG. The lighting equipment management unit 60 includes a power supply unit 61, a control unit 62, and transfer input units 63-1 to 63-R (R: natural number).

  The power supply unit 61 receives power supply from an AC power supply or a battery power supply, and supplies power to the control unit 62 and the message input units 63-1 to 63-R. The message input units 63-1 to 63-R receive various signals from the outside. For example, the report input units 63-1 to 63-R are associated with the report output units 34-1 to 34-P of the light alarm control device 30, and the report output units 34-1 to 34-P. The linked message signals from are input to message input units 34-1 to 34-P in accordance with the association (assignment). The control unit 62 includes one or more lighting facilities 70 provided for each of the management areas M1 to MS (S: natural number) based on the interlocking transfer signal input to the transfer input units 63-1 to 63-R. Dimming control is performed. For example, one or more lighting equipments 70 installed in each of the management areas M1 to MS are connected by the same control line drawn from the control unit 62, and the control unit 62 is connected to the same management area via the control line. The dimming control of the lighting equipment 70 can be performed synchronously.

  For example, as shown in FIG. 6, the dimming level of the lighting equipment 70 is brightened in n stages (n: natural number) from the dimming level at which normal illumination is performed, and in m stages (m: natural number). It can be adjusted to darken. In addition, the setting of the number of steps of the dimming level such as n steps and m steps can be arbitrarily set, and the dimming level can be set, for example, without using stepwise settings such as m steps and n steps. As shown by the curve X, it may be configured to switch in a stepless manner (in an analog manner).

  Next, a dimming pattern of dimming control executed by the control unit 62 will be described with reference to FIG. The white polygon in the figure indicates that the light alarm device 40 is performing a light alarm. When the light alarm by the light alarm device 40 is finished, for example, the control unit 62 controls the lighting equipment 70 to have normal illuminance. The dimming pattern is not limited to the dimming patterns shown in FIGS. 7A to 7E below.

  FIG. 7A shows a dimming pattern in which the control unit 62 changes the illumination illuminance of the lighting equipment 70 (darker or brighter than normal illuminance) from when the light alarm device 40 starts the light alarm to when it ends. Indicates. For example, the control unit 62 performs the dimming control based on the interlocking transfer input ON signal S11 and the interlocking transfer input OFF signal S12 received from the light alarm control device 30.

  FIG. 7B shows a dimming pattern in which the control unit 62 changes the illumination illuminance of the lighting equipment 70 only for a predetermined time after the light alarm device 40 starts the light alarm. For example, the control unit 62 starts changing the illuminance when the interlocking transfer input ON signal S13 is received, and automatically ends the change of illuminance after a predetermined time has elapsed from the start. Instead of automatically ending the change in illuminance, as shown in the figure, the change in illuminance may be ended when the interlocking transfer input OFF signal S14 is received after a predetermined time has elapsed. . Moreover, FIG.7 (c) shows the light control pattern which repeats the control of the said FIG.7 (a) or (b).

  FIG. 7D shows a dimming pattern in which the control unit 62 changes the illuminance of the lighting equipment 70 based on a preset time table. For example, when the interlocking transfer input ON signal S15 is received, the control unit 62 starts changing the illuminance and darkens (or brightens) the illuminance from normal. Then, when it is time to switch from the first time zone (for example, daytime) to the second time zone (for example, nighttime), the control unit 62 increases (or darkens) the illuminance again. Then, when it transfers to a predetermined time slot | zone, the illumination of the lighting installation 70 will be returned to normal. Note that the timing at which the control unit 62 changes the illuminance is not limited to that based on the time zone, and the illumination facility management unit 60 and an illuminance measurement device (not shown) installed in each management area are directly or indirectly connected. Then, the illuminance may be changed at the timing when the measured illuminance of the illuminance measuring apparatus changes to a predetermined value.

  FIG. 7E shows a dimming pattern in which the control unit 62 changes the illuminance of the lighting equipment 70 when the illumination is turned off in the initial state. For example, when the interlocking transfer input ON signal S16 is received, the control unit 62 turns on the lighting of the lighting equipment 70 with the normal illuminance and then maintains the illumination illuminance to normal or changes (darker or brighter). Shine. In addition, when this illumination intensity is made dark or bright, you may make it return the illumination intensity of the lighting installation 70 to normal after progress for a predetermined time.

  Next, interlocking control between the light alarm control of the light alarm device 40 and the illumination control of the lighting equipment 70 will be described. FIG. 8 and FIG. 9 are flowcharts showing an example of the interlock control. In the control, the CPU 53 of the receiving device 50 receives the disaster detection signal from the disaster detection line DL, and the CPU 53 controls the bell control circuit 54 based on this. The process is started when the bell control circuit 54 that transmits the signal and receives the signal outputs a control signal for ringing the bell 20 to the bell line BL.

  When the bell control circuit 54 outputs a control signal for ringing the bell 20 to the bell line BL, the control signal synchronization pulse (light) for ringing the bell 20 from the light alarm control device 30 to the light alarm line KL is received. Alarm control signal) is output. Based on this synchronization pulse, the optical alarm device 40 connected to the optical alarm line KL starts an optical alarm (ST101).

  When the light alarm device 40 starts a light alarm, the interlocking relocation signal is transmitted from, for example, the relocation output unit 34-1 to the relocation input unit 63-1 of the lighting equipment management unit 60. Here, for example, the transfer output unit 34-1 and the transfer input unit 63-1 are associated with each other so as to control the same management area. For this reason, the illumination facility management unit 60 performs illumination dimming of the illumination facility 70 in the management area corresponding to the transfer input unit 63-1 (one corresponding to the transfer input unit 63-1 among the illumination facilities M1 to MS). Control is started based on the interlocking transmission signal (ST102). Thereby, in the said management area | region, the light alarm control of a light alarm and the illumination light control of a lighting installation are interlocked and performed.

  After starting the interlock control in this way, the CPU 53 determines whether or not the light alarm recovery condition is satisfied (ST103). This determination is made based on, for example, whether or not a recovery button (not shown) provided in the receiving device 50 is pressed to return the light alarm system 1 from the alarm state to the normal state. If it is determined that the light alarm recovery condition is not satisfied (ST103: NO), the CPU 53 continues the state in which the determination is performed.

  On the other hand, when it is determined that the light alarm recovery condition is satisfied (ST103: YES), the CPU 53 (bell control circuit 54) stops the ringing control of the bell 20. As a result, the ringing of the bell 20 stops and the light alarm controlled in conjunction with the bell 20 stops (ST104).

  Further, the light alarm device controller 30 stops the output of the interlocking transfer signal to the lighting equipment management unit 60 by stopping the ringing control of the bell 20. For this reason, the lighting equipment management unit 60 changes the lighting of the lighting equipment 70 that has been dimming-controlled based on the interlocking transfer signal to an initial state, for example, normal illuminance (ST105). Thereby, the light control of the lighting equipment 70 is complete | finished.

  Note that the processing order in FIG. 8 can be varied. For example, as shown in the flowchart of FIG. 9, the light alarm start (ST101) and lighting equipment dimming start (ST102) processes are interchanged to obtain lighting equipment dimming start (ST201) and light alarm start (ST202). The processing of the alarm stop (S104) and the illumination facility normal illuminance (S105) may be exchanged to obtain the illumination facility normal illuminance (ST204) and the light alarm stop (ST205).

  Next, the operation of the interlock control will be described with reference to an installation example of the light alarm system 1 illustrated in FIG. As shown in FIG. 10, the room R is divided into a small room (management area) R1 that occupies a corner of the room R and a large room (adjacent management area) R2 that is adjacent to the small room R1. It is possible to enter and exit each other's room. In addition, in FIG. 10, illustration is abbreviate | omitted except the structure which paid its attention to said interlock control.

  The disaster sensing line DL1 is drawn into the room R1 from the receiving device 50, and the disaster sensing line DL2 is drawn into the room R2. A plurality of disaster detectors 10 are connected in parallel to the disaster detection lines DL1 and DL2, respectively. Further, the light warning line KL1 is drawn from the light warning control device 30 to the room R1, and the light warning line KL2 is drawn to the room R2. A plurality of optical alarm devices 40 are connected in parallel to the optical alarm lines KL1 and KL2. Further, the control line L1 for turning on / off or dimming the light of the lighting equipment 70 from the lighting equipment management unit 60 (hereinafter collectively referred to as “light control”) is drawn to the room R1, and the control line L2 is drawn to the room R2. ing. One or a plurality of lighting facilities 70 are connected to the control lines L1 and L2, respectively. The plurality of disaster detectors 10, the plurality of light alarm devices 40, and the plurality of lighting facilities 70 are installed, for example, on the ceiling surface or wall surface of the small room R1 or the large room R2 corresponding to the position shown in FIG. Moreover, the light warning area | region of each light warning device 40 and the illumination area | region of each lighting installation 70 have overlapped a part or all. That is, the management area R1 and the lighting area of the lighting equipment provided in the small room R1 partially or entirely overlap each other. And the adjacent management area | region R2 and the illumination area | region of the lighting installation provided in the large room R2 have a part or all overlapping mutually.

  Now, in the light alarm system 1 configured as described above, the disaster detector 10 in the small room R1 (for example, the disaster sensor in the small room R1 with the diagonal line in the upper right in the figure) detects a disaster such as a fire. In this case, the receiving device 50 receives the disaster detection signal via the disaster detection line DL1. Then, the receiving device 50 sends an optical alarm control signal linked to the control signal of the bell 20 to the optical alarm device 40 connected to the optical alarm line KL1 via the bell line BL (not shown) and the optical alarm control device 30. Output. Thereby, the light alarm device 70 in the small room R1 starts a light alarm. On the other hand, from the transfer output unit 34-1 of the light warning control device 30, an interlocking transfer signal linked with the light warning control signal is output to the corresponding transfer input unit 64-1 of the lighting equipment management unit 60. . Here, the transfer output unit 34-1 and the transfer input unit 64-1 are associated in advance in a one-to-one correspondence. Both are set corresponding to the same management area. For this reason, the lighting installation management part 60 can dimm the illumination of the lighting installation 70 in the small room R1 darkly, for example. In this way, dimming control is performed so that the illumination of the lighting equipment 70 in the small room R1 where a disaster is detected becomes highly visible in the light alarm of the light alarm device 40.

  Further, when the receiving device 50 receives a disaster detection signal from the disaster detection line DL1, for example, the light alarm control device 30 outputs a linked transfer signal to the lighting equipment management unit 60 via the transfer output unit 64-2. Here, the transfer output unit 64-2 corresponds to the small room R1 and the large room R2 adjacent to the small room R1, and the lighting equipment management unit 60 determines the lighting equipment 70 of the large room R2 based on the interlocking transfer signal. Dimming control of lighting. For example, when the lighting equipment 70 in the large room R2 is turned off, the lighting equipment management unit 60 adjusts the lighting of the lighting equipment 70 so as to obtain normal brightness. This makes it easier for people in the small room R1 to move to the large room R2 via the entrance D when a disaster occurs.

  As described above, in the optical alarm system 1, the receiving device 50 controls the optical alarm of the optical alarm device 40 for the optical alarm line KL corresponding to the disaster detection line DL based on the disaster occurrence signal output from the disaster detection line DL. To do. In this case, the lighting equipment management unit 60 receives the interlocking signal that is interlocked with the light alarm control signal from the light alarm controller 30 and, based on the received interlocking signal, matches the light alarm region of the light alarm. Dimming control can be performed on the illumination of the illumination facility 70 that illuminates an illumination area in which some or all areas overlap. For example, the visibility of the light alarm can be ensured by the dimming control so that the lighting facility management unit 60 makes the lighting of the lighting facility 70 darker than the normal brightness. For this reason, the situation where the visibility of a light alarm falls by the environment and time zone which perform a light alarm can be avoided.

  Further, when the receiving device 50 performs the light alarm control of the light alarm device 40 in the small room R1 based on the disaster detection of the disaster detector 10 in the small room R1, the inside of the small room R1 is based on the interlocking transmission signal. The dimming control of the lighting of the lighting equipment 70 is synchronized with the light alarm control of the light alarm device 40. For this reason, for example, the visibility of the light alarm can be ensured at any location in the small room R1.

  Furthermore, when performing said light alarm control, the lighting installation management part 60 light-controls the lighting installation 70 in the large room R2, for example brightly based on an interlocking transmission signal. For this reason, when evacuating from the small room R1 where the disaster occurred to the large room R2 adjacent to it or through the large room R2, the large room R2 is dark and it is difficult to see the evacuation route or evacuation site. The situation can be avoided. Further, the difference in brightness between the small room R1 and the large room R2 can be used to show the evacuation direction more clearly and effectively to the people in the room R1, and the inside of the large room R2 becomes brighter. It becomes easy to check the environment in the room, and it is also possible to quickly evacuate from the large room R2 in a safer direction.

(Second Embodiment)
Next, a second embodiment will be described. The second embodiment is different from the first embodiment described above in that the light alarm device 40 controls the luminous intensity of the light alarm. Therefore, this point will be described in detail below. In addition, the same code | symbol is attached | subjected to the structure same as 1st Embodiment demonstrated previously, and detailed description about the same structure is abbreviate | omitted.

  FIG. 11 is a diagram showing a configuration of the light alarm device 40 in the second embodiment. As shown in FIG. 11, the light alarm device 40 of this embodiment has an illuminance measuring unit 45 and a light emission pattern recording unit 46, which are connected to the control unit 42 in the light in FIG. 4. Different from the alarm device 40. The illuminance measuring unit 45 corresponds to the illuminance measuring device in the claims, and measures the illuminance of the area where the light alarm of the light alarm device 40 is performed. The light emission pattern recording unit 46 stores a plurality of light emission patterns having different light intensity (light emission intensity of the light emission unit) for performing a light alarm. The control unit 42 selects one of the light emission patterns stored in the light emission pattern recording unit 46 based on the illuminance measured by the illuminance measurement unit 45, and performs a light alarm based on the selected light emission pattern. The light emission pattern selection method of the control unit 42 is, for example, a method of selecting a light emission pattern on a one-to-one basis such as a light emission pattern of a certain luminous intensity for a certain illuminance, or a certain luminous intensity or more A method of arbitrarily selecting one light emission pattern from the light emission patterns is conceivable, but is not limited thereto.

  As described above, the light alarm device 40 according to the second embodiment includes the illuminance measurement unit 45 that measures the illuminance of the light alarm emission region, and the control unit 42 measures the illuminance measurement unit 45. Since the luminous intensity of the light emitted from the light emitting unit 43 can be changed based on the illuminance, the visibility of the light alarm can be ensured more finely. For example, when the light intensity is changed before the start of the light alarm, or when the lighting of the lighting equipment 70 is controlled to be brightly dimmed, the illuminance before the light alarm (hereinafter referred to as “the first light alarm”) is added. 1 illuminance ”) and illuminance every predetermined time (hereinafter referred to as“ second illuminance ”), and when the illuminance difference obtained by subtracting the first illuminance from the second illuminance is not equal to or greater than a predetermined value, To do. For example, when comparing the illuminance every predetermined time, if there is a possibility that smoke or the like may be generated and the light alarm becomes invisible, the light intensity of the light alarm is increased regardless of the state of the dimming control of the lighting of the light equipment 70 Visibility can be ensured.

  In each of the above embodiments, the light warning control device 30 is connected to the terminal of the bell line BL drawn from the receiving device 50, that is, the light warning line KL is indirectly connected to the receiving device 50. However, the present invention is not limited to this, and the optical alarm line KL may be directly drawn out from the receiving device 50.

  Moreover, in each said embodiment, although the interlocking transmission signal input into the lighting installation management part 60 demonstrated the case where it was output from the light alarm control apparatus 30 or the light alarm apparatus 40, it is not restricted to this, For example, You may comprise so that it may output from the external transmission circuit 55 of the receiver 50. FIG. That is, the interlocking transfer signal may be configured to be input to the lighting equipment management unit 60 from at least one of the light alarm control device 30, the light alarm device 40, and the reception device 50.

(Modification)
Next, modifications of the above embodiments will be described. This modification is a case where it is constituted so that the interlocking transmission signal is output from each of the light alarm devices 40 to the lighting equipment management unit 60. Moreover, as shown in FIGS. 12 to 14, the light alarm area of each light alarm device 40 and the illumination area of the lighting equipment 70 are configured to partially or completely overlap each other, and light in each management area The alarm device 40 is configured to perform an optical alarm in conjunction with it. FIGS. 12 to 14 show three patterns in which the light alarm device 40 controls the lighting equipment 70 in conjunction with each other. In the three patterns, one light alarm device 40 controls the lighting equipment 70 in conjunction with each other. Pattern (see FIG. 12), a pattern in which one light alarm device 40 controls a plurality of lighting equipments 70 (see FIG. 13), and a plurality of light alarm devices 40 controls one lighting equipment 70 in conjunction. Pattern (see FIG. 14). As shown in FIGS. 12 to 14, the light alarm device 40 (40 a to 40 c) performs a light alarm synchronously, and the lighting equipment management unit 60 uses the interlocking transfer signal from the light alarm device 40 to make the lighting equipment 70 (70 a And 70b) can be controlled in conjunction with all the light alarm devices 40 and the lighting equipment 70 in the management area.

  Here, an example of the interlock control by the light alarm device 40 will be described. For example, as shown in FIG. 15, among the lighting facilities 70a to 70e, for example, the lighting facilities 70a to 70c are installed in the management area M1, and the lighting facilities 70d and 70e are installed in the adjacent management area M2 adjacent to the management area M1. And In FIG. 15, “white circle” indicates a state where the illumination of the lighting equipment 70 is controlled brighter than usual, and “black circle” indicates a state where the lighting equipment 70 is controlled darker than usual.

  FIG. 15A shows that when the management area M1 is an alarm area (a management area where a disaster has occurred), the lighting facilities 70a to 70c in the management area M1 are interlocked and controlled based on the interlocking transfer signals S1 to S3. Shows the case. When each of the interlocking transfer signals S1 to S3 is input to the corresponding transfer input unit 63, the control unit 62 dimmes the lighting facilities 70a and 70b and brightens the lighting facility 70c. Thereby, interlocking control of the lighting equipment 70a-70c of the management area | region M1 can be performed. The reason why the lighting equipment 70c is dimmed brightly is, for example, to indicate the vicinity of the entrance (or the evacuation direction) to people in the management area M1 when a disaster occurs.

  FIG. 15B shows a case where when the management area is M1, the lighting equipments 70a to 70e in the management area M1 and the adjacent management area M2 are interlocked and controlled based on the input interlocking message S4. ing. When the interlocking transfer signal S4 is input to the corresponding transfer input unit, the control unit 62 dimmes the illumination facilities 70a and 70b darkly, dimmes the illumination of the illumination facility 70c, and further controls the illumination facility 70d. , 70e are brightly dimmed.

  Even when configured as in this modification, the same effects as those of the first and second embodiments can be obtained. Note that the correspondence between the interlocking transfer signal and the illumination of each lighting facility 70 and the setting of the light control are not limited to the example of FIG. 15 and can be arbitrarily set.
