Description

  The present invention relates to a guidance lighting system, and more particularly, to a guidance lighting system that guides people in an appropriate direction using lighting installed in a building.

  In buildings such as accommodation facilities and commercial facilities, it is very important to guide people in the building safely and promptly outside the building in the event of a fire. Conventionally, when a fire breaks out, an emergency bell rings and then the situation is communicated by broadcasting in the building. The people in the hall listen to the in-house broadcast and evacuate to the evacuation exit according to the guide light indicating the evacuation exit and the guidance of the staff.

  During emergency evacuation, the earlier the initial evacuation, the less damage can be expected and the higher safety can be secured. However, it takes some time for the situation to be communicated by in-house broadcasting after the fire breaks out. In addition, an audio broadcast that informs about each part may flow throughout the hall. In this case, there is a problem that it is difficult to understand a route that is appropriate for the user. For example, in a multi-storey building, when the situation of each floor is voice-guided to all the floors, it may be difficult to quickly determine what information is on the floor where the person is. That said, if you switch broadcasts for each floor or for each area and only flow information for that floor or that area, there will be a time error, and there will be a time when broadcast will not flow in one place. It will be long and will be very uneasy for people in the hall. Furthermore, with voice guidance, it may be difficult to hear the voice due to confusion, and it may be difficult for a person who does not know the structure of the hall to evacuate in an appropriate direction with only voice guidance.

  In response to such a problem, there has been proposed a system that displays an evacuation direction by installing a lighting device for evacuation guidance on the floor and sequentially flashing in the direction to evacuate. For example, Patent Document 1 includes an N-ary counter and a light source, and lamps that turn on the light source when the count number of the N-ary counter matches a preset count number are arranged along an evacuation route. In addition, it is described that the evacuation direction is displayed by sequentially lighting the lamps by up-counting or down-counting with the intersection or branching part of the corridor as the center point.

  In Patent Document 2, guidance devices (lighting fixtures) in which visible super-bright LEDs are arranged on both left and right sides are installed on the wall and floor of a building, and irradiation from the guidance device is performed selectively on the left and right. The evacuation guidance is always performed by irradiating the evacuating person from the direction of the evacuation exit.

Japanese Patent Laid-Open No. 5-120575 JP 2006-99710 A

  In this way, by arranging lighting for evacuation guidance on the floor or wall and lighting it so as to guide it to the evacuation exit, people in the building can evacuate properly faster than guidance by only the guide light and audio broadcasting. The direction can be determined. However, in the above-described prior art, it is necessary to install evacuation guidance lighting in the entire building separately from normal lighting, which increases costs. In addition, a large-scale renovation work is required to newly install lighting for evacuation guidance in an existing building, which requires a lot of time and cost. Furthermore, depending on the structure of the floor or the like, it may be difficult to install such illumination.

  On the other hand, in a building having a plurality of event venues such as movie theaters and public facilities, people who leave the venue after the event etc. go to the exit looking at the guidance display in the hall. Here, if the guidance is difficult to understand or the information is overlooked, the exit person may get lost in other event venues or restricted areas, etc. Sometimes. However, a system that appropriately guides the residents in such a case has not been proposed.

  The present invention has been made in view of such a situation, and an in-house person can intuitively determine a route to be taken such as an optimum evacuation route or a leaving route, and can be used in an existing building. Even if it exists, let it be a main subject to provide the induction | guidance | derivation lighting system which can be deployed at low cost irrespective of the structure.

  In order to solve the above problems, the present invention provides a plurality of detectors installed in a building, a plurality of lighting devices that illuminate the inside of the building, and a detection signal from the detector to identify the position of the leaving origin A determination unit that receives a determination result from the specification unit and determines a guide route from the inside of the building to the outside, and gradually toward a direction to be guided according to the guide route determined by the determination unit And a control unit that controls the illumination device so as to be bright.

  Further, the detector is a fire detector, the specifying unit receives a detection signal from the fire detector, specifies a fire occurrence place as the retreat origin, and the determining unit receives from the specifying unit. It is good also as receiving the specific result and determining the evacuation guidance route from the inside of the building to the outside.

  Further, the control unit turns off the illumination of the exit origin and the passage and lifting means inappropriate for use of the exit, and the direction from the departure origin and the passage inappropriate for use of the exit and the lifting means to the outside exit. It is good also as controlling the illumination intensity of the said several illuminating device so that it may become bright gradually.

  Further, the control unit turns off the illumination of the exit origin and the passage and lifting means inappropriate for use of the exit, and the direction from the departure origin and the passage inappropriate for use of the exit and the lifting means to the outside exit. The lighting and extinguishing of the plurality of lighting devices may be controlled so as to gradually increase the number of the lighting devices that are turned on as proceeding to.

  According to the induction lighting system of the present invention, the residents can intuitively determine the optimum evacuation route and exit route, and even if it is an existing building, the cost is low regardless of its structure. Can be deployed.

  Hereinafter, an induction lighting system according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a first embodiment of the induction lighting system of the present invention. A guided lighting system 10 shown in FIG. 1 guides people in a building to an evacuation exit by using a normal lighting device when a fire occurs in a building such as an accommodation facility or a commercial facility. System. The induction lighting system 10 includes a plurality of fire alarms (fire detectors) 12 installed at various locations in a building, a control device 14, and a plurality of lighting devices 16 installed throughout the building.

  The fire alarm 12 has one or a plurality of functions such as a conventionally used push button type, heat detector, and smoke detector. Each of the plurality of fire alarms 12 is connected to the control device 14. When a fire is detected, an emergency bell is sounded to alert the surroundings and a fire detection signal is sent to the control device 14. The fire alarm 12 may have a function of directly reporting to the fire engine.

  The control device 14 includes a fire source identification unit 18, a guidance route determination unit 20, a hall route DB (database) 22, and a lighting control unit 24. Upon receiving a fire detection signal from the fire alarm 12, the fire source identification unit 18 identifies the fire source (fire occurrence location) that is the departure origin based on the identifier of the fire alarm 12, and identifies the fire source Information is sent to the guide route determination unit 20.

  In the hall route DB 22, evacuation route data corresponding to the location of the fire in the hall is stored in advance. The guide route determination unit 20 searches the hall route DB 22 based on the fire source specifying information received from the fire source specifying unit 18, reads out the data of the evacuation route corresponding to the fire source specifying information, and determines it as the guide route. Then, information on the guidance route is sent to the lighting control unit 24. The lighting control unit 24 controls the lighting devices 16 at various locations in the hall so as to gradually become brighter in the direction to be guided according to the guidance route determined by the guidance route determination unit 20.

  In the hall route DB 22, routine route data such as halls, stairs, and evacuation exits in the hall are stored, and the guidance route determination unit 20 receives the fire source identification information from the fire source identification unit 18 and the hall route. The guidance route may be determined by calculating the evacuation route from the route data in the DB 22.

  The lighting device 16 can be a normal lighting device such as an incandescent lamp or a fluorescent lamp.

  FIG. 2 is a flowchart showing processing in the control device 14. As shown in FIG. 2, during normal times, the guidance route determination unit 20 of the control device 14 sets each evacuation route assuming that each place in the hall is a fire source, and accumulates the data in the hall route DB 22 (steps). S1), the lighting control unit 24 controls the lighting in the hall to a normal lighting state (step S4).

  On the other hand, in the event of a fire, when the control device 14 receives an alarm signal (fire detection signal) from the fire alarm 12 (step S2), the guide route determination unit 20 calculates or selects an evacuation route according to the location of the fire ( In step S3), lighting in the hall is controlled according to the determined guide route (step S4).

  Here, the control method of the illuminating device 16 by the illumination control part 24 is demonstrated concretely. FIG. 3 is a plan view showing an example of a building using the induction lighting system 10. The floor 30 shown in the figure is a floor of one floor (N floor) in a multi-story building, and the rooms 32 and 38 that continue on both sides in the longitudinal direction of the floor 30 and the rooms provided in the center portion of the floor 30. 34, 36, steps 40, 42, 44 provided at the left end, the center and the right end in the figure, passages 46, 48 between the living rooms, and lighting arranged at predetermined intervals on the ceiling of the passages 46, 48 Illumination devices 50 (50a, 50b, 50c...) And 52 (52a, 52b, 52c...) Constituting the device 16 are included. Although the lighting device is actually arranged also in the living room or the staircase portion, only the lights 50 and 52 provided in the passages 46 and 48 will be described here for the sake of clarity.

  For example, all lighting devices in the living room may be turned on during normal times and turned off when a fire occurs, and all lighting devices in the staircase are normally turned on during use and are dangerous to use in the event of a fire. The staircase portion (for example, the staircase 42) that is safe may be turned off, and the staircase portions that are safe to use (for example, the staircases 40 and 44) may be turned on.

  During normal times, the illumination control unit 24 of the guidance lighting system 10 turns on all the lighting devices 50 and 52 and illuminates all the passages of the floor 30. On the other hand, in the event of a fire, for example, when the fire source 54 is the living room 34, the area around the living room 34 and the area of the staircase 42 near the living room 34 darken, and the staircases 40 at both ends that serve as safe evacuations from the fire source 54 The lighting devices 50 and 52 are controlled so as to become brighter toward the heads 44 and 44.

  FIGS. 4A and 4B are schematic views for explaining a specific example of lighting control in the event of a fire on the floor 30 of FIG. In FIG. 4, of the floor 30, the stairs 40, 42, 44, the lighting devices 50 (50 a, 50 b, 50 c...) And 52 (52 a, 52 b, 52 c. It is shown.

  If the illumination devices 50 and 52 can change the illuminance by using a dimmer or the like, such as an incandescent lamp, the illumination control unit 24, as shown in FIG. Illumination devices 50 and 52 in the area of 54 and its nearest staircase 42 are turned off, and the illuminance is increased so as to gradually increase the illuminance of the illumination devices 50 and 52 from the fire source 54 and the stairs 42 to the left stairs 40. Control. Similarly, on the right side, the illuminance is controlled so as to gradually increase the illuminance of the lighting devices 50 and 52 from the fire source 54 and the stairs 42 toward the stairs 44.

  Further, as shown in FIG. 4B, the lighting control unit 24 turns off the lighting devices 50 and 52 in the area of the fire source 54 and the nearest staircase 42, and the stair 40 or the staircase from the fire source 54 and the staircase 42. As it goes to 44, the number of lighting devices 50 and 52 to be lit is increased gradually, such as every third, every second, every other, and the stairs 40 and the vicinity of the stairs 44 are all lit to light up. By controlling the number of lighting devices present, it may be gradually brightened from the fire source 54 and the stairs 42 toward the safe stairs 40 or stairs 44. The form of FIG. 4 (B) can also be employed when the illumination devices 50 and 52 are illumination devices that are difficult to change illuminance, such as fluorescent lamps.

  In this way, people in the building can make dangerous areas and safe by dimming the lighting in the vicinity of the source of fire and in the areas of elevators and passages that are not suitable for use, and by increasing the lighting in a direction that allows safe evacuation. It is possible to intuitively determine the area and evacuate quickly in a safer direction. That is, the guidance lighting system 10 can safely evacuate people by controlling the lighting device as described above.

  Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram showing a schematic configuration of the second embodiment of the induction lighting system of the present invention. The guided lighting system 60 shown in the figure is usually used when an event at one venue ends in a building having a plurality of venues on one floor, such as an event venue (for example, a movie theater or a public facility). This is a system for guiding people leaving the venue to the exit from the building or the floor using the lighting device for lighting. The induction lighting system 60 includes a door opening detector 62 attached to a door of each venue, a control device 64, and a plurality of lighting devices 66 installed in the entire area of the building.

  The control device 64 includes a door specifying unit 68, a guidance route determination unit 70, a hall route DB 72, and a lighting control unit 74. Upon receiving a signal from the door opening detector 62, the door specifying unit 68 specifies the opened door based on the identifier of the door opening detector 62 and sends the door information to the guidance route determination unit 70.

  In the hall route DB 72, routes from each venue in the hall to the exit are stored in advance. The guidance route determination unit 70 searches the hall route DB 72 based on the door identification information received from the door identification unit 68, reads the route data from the venue where the door is opened to the floor exit, and determines it as the guidance route. Then, information on the guidance route is sent to the illumination control unit 74. The lighting control unit 74 controls the lighting devices 66 in various places in the hall so that the light gradually becomes brighter in the direction to be guided according to the guidance route determined by the guidance route determination unit 70.

  It should be noted that regular route data such as passages, stairs and exits in the hall are stored in the hall route DB 72, and the guidance route determination unit 70 receives the door identification information from the door identification unit 68 and the route data in the hall route DB 72. The guide route may be calculated and determined based on the same as in the first embodiment.

  As the lighting device 66, a normal lighting device such as an incandescent lamp or a fluorescent lamp can be used.

FIG. 6 is a plan view showing an example of a building using the induction lighting system 60. The floor 80 shown in the figure has six event venues 82, 84, 86, 88, 90, 92, door opening detectors 62 (62a to 62f) provided near the doors of the respective venues, and event venues 82 to 82. A passage 94 provided in the center of 92, an outlet 96 of the floor 80, and a lighting device 66 arranged at a predetermined interval on the ceiling of the passage 94 are provided.
In FIG. 6, lighting in the event venue, lighting in the lobby near the exit 96, and the like are omitted for the sake of clarity.

  When an event at each event venue 82 to 92 is in progress or there is no event, and all the venue doors are closed, the illumination control unit 74 of the guidance illumination system 60 turns on or turns off all the illumination devices 66. When the event at one of the event venues ends and the door is opened, the lighting control unit 74 causes the passage 74 from the event venue to the exit 96 of the floor 80 to gradually become brighter toward the exit. The lighting device 66 is controlled.

  For example, as shown in FIG. 6, when the event at the venue 84 ends and the door of the venue 84 is opened, it is detected by the door open detector 62b. Next, the door specifying unit 68 of the control device 64 specifies that the door of the venue 84 is opened, that is, the exit origin is the venue 84, and then the guidance route determining unit 70 A guide route from the event venue 84 to the exit 96 is determined. The illumination control unit 74 turns off the illumination in the direction opposite to the exit 96 from the venue 84 in the illumination device 66 according to the determined guidance route information, and gradually increases the illumination from the venue 84 toward the exit 96. For the control of the lighting device 66, the same method as in the first embodiment can be used.

  In this way, when the audience leaves from one event venue, by turning off the lighting in the area opposite to the exit from the venue or in the area where entry is prohibited, The direction of the exit can be determined intuitively, and you can quickly proceed to the exit without getting lost in the hall. That is, by controlling the illumination as described above, the guidance lighting system 60 can promptly guide people to the exit without entering another venue or a prohibited area.

  Although the induction lighting system of the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various improvements and modifications may be made without departing from the gist of the present invention. For example, in the above description, an example in which people exiting from an event venue are guided to an exit has been described. However, the guided lighting system of the present invention is applied to a form in which people are guided by a predetermined route according to the progress of the event. You can also
