Description

  In the present invention, in the event of a disaster such as an earthquake, a large-scale fire, or a tsunami, a powerful guide beam projected from a high place is optically scanned along an evacuation route set only on a road that can be safely passed without damage. Thus, the present invention relates to an evacuation guidance system using a light beam for guiding a evacuation route so that the user can quickly and surely reach a predetermined evacuation place by moving the evacuation route while viewing the guidance light beam.

  In the event of a sudden disaster such as an earthquake, large-scale fire, or tsunami, it is necessary to evacuate to a safe evacuation site immediately. Therefore, in each region, evacuation drills are usually conducted by setting in advance a safe evacuation site and an evacuation route that can reach the evacuation site through a safe road in the shortest distance. However, when a large-scale disaster occurs, some of the roads on the evacuation route that residents are familiar with may be inaccessible due to collapsed buildings or severe large-scale fires. Even inhabitants who have undergone evacuation drills, it is possible that they will lose normality and panic. In addition, it is expected that there are various unexpected difficulties in evacuating people and travelers who do not participate in regular evacuation drills even if they are residents of the area.

  Therefore, conventionally, various evacuation guidance systems have been proposed in which the above-described problems are solved. The first evacuation guidance system installs an evacuation guidance device in many places where many residents come and go, such as urban areas and parks, and this evacuation guidance device is a map displayed on a map information display section. The fire occurrence position is displayed by turning on or blinking the LED provided above, and the LED provided on the evacuation route in the map information display section is displayed for the evacuation route from the fire occurrence location to the specified evacuation location Or, it is displayed by blinking, and when the current position exists on the evacuation route, the light irradiation direction of the evacuation direction indicator is controlled to be directed to the evacuation direction and guided to the evacuation place (for example, , See Patent Document 1).

  In addition, the second evacuation guidance system installs lighting fixtures on a plurality of routes that can be evacuation routes, detects the number of people around each lighting fixture, and transmits them to the control device. And a function of transmitting an optical signal indicating the evacuated route. Then, the control device designates the route with the smaller number of detected persons as the evacuation route with respect to the luminaire provided at the branch point of the two routes that can be selected as the evacuation route. The control which performs is performed (for example, refer patent document 2).

  Further, the third evacuation guidance system is to install a guidance guide plate at a place where a large number of residents come and go, and displays a disaster occurrence location using a plurality of light emitting elements of each guidance guide plate. In the evacuation route from the installation location of the guide plate to the evacuation site, a plurality of route guidance devices having light emitters indicating the traveling direction of the evacuation route are arranged along the evacuation route, and the plurality of route guidance devices Are lit in order from the first stage near the guidance guide plate toward the last stage near the evacuation place to display the evacuation route (see, for example, Patent Document 3).

JP 2008-234250 A JP 2009-26148 A JP 2010-2111648 A

  In the first evacuation guidance system, based on the position of the LED that is lit or blinking on the display map of the map information display unit in many evacuation guidance devices installed at all of the branch point positions of the plurality of passages. The fire occurrence position and the route from the fire occurrence place to the evacuation place are displayed, and the evacuation direction from the current position to the evacuation place is displayed according to the light irradiation direction of the evacuation direction indicator. However, for those who are rushing to the evacuation site in a psychological situation where they have lost their normal feelings due to a disaster, they must stop at each installation location of each evacuation guidance device and fully understand the evacuation route of the displayed contents. The evacuation route set and displayed cannot be fully understood by a person who is expected to have no room, and especially a person such as a traveler who hardly knows the geography around the disaster occurrence area. In addition, even if the person who intends to fully understand the displayed contents, whether or not the road that is actually moving is the evacuation route displayed on the evacuation guidance device when he / she is away from the installation location of the evacuation guidance device It may be possible to follow up if the evacuation behavior causes anxiety because the user cannot confirm the situation, and the evacuation behavior goes back, or if someone along the evacuation behavior travels on the wrong road together. As described above, in this evacuation guidance system, the evacuation route set excluding the inaccessible road due to the occurrence of a disaster is displayed by the map information display unit in many evacuation guidance devices. It seems difficult to guide to the evacuation site quickly and smoothly.

  Moreover, in the first evacuation guidance system, the number of evacuation guidance devices increases as it is necessary to install evacuation guidance devices at all the branch point positions of the plurality of passages included in the evacuation route. However, when evacuation routes are set in a wide area, there is a problem that the number of evacuation guidance devices is increased and the installation cost becomes too high even though smooth and quick evacuation guidance cannot be performed as described above. . Further, in the first evacuation guidance system, the disaster countermeasure center transmits disaster location identification information for identifying the location of the disaster occurrence location to each evacuation guidance device, and each evacuation guidance device receives the received disaster. The optimum evacuation site was identified based on the occurrence location identification information, the map information, the location information of the evacuation site, and the current location information on the guidance map, and the evacuation route to the identified evacuation site was retrieved based on the map information. Later, since this very complicated control for displaying the evacuation route on the guidance map is performed, this also increases the cost.

  The second evacuation guidance system has a function in which each luminaire installed on each of a plurality of routes that can serve as an evacuation route detects the number of people around and transmits it to the control device, and an evacuation route designated by the control device. A portable communication terminal having a function of transmitting an optical signal indicating that the portable communication terminal carried by the evacuee receives the optical signal transmitted from the lighting equipment and indicates the position indicated by the optical signal and the evacuation route. It has the function to notify to. Therefore, this second evacuation guidance system is designed to prevent the evacuation route from being crowded in order to avoid a large number of evacuees rushing to a specific evacuation route among a plurality of evacuation routes leading to each emergency exit in the building. It is intended to select a suitable evacuation route according to the degree, and in the event of a large-scale disaster, select only a safe outdoor road and guide it to the evacuation site through the set evacuation route Cannot be adopted.

Further, the third evacuation guidance system displays a disaster occurrence location using a plurality of light emitting elements provided on each guidance guide plate installed in a place where a large number of residents come and go. Compared to the first evacuation guidance system, the light emitters of the plurality of route guidance slave units are moved from the first stage near the guidance guide plate to the final stage near the evacuation site. There is only an advantage that the evacuation route is somewhat easy to confirm in that the evacuation route is displayed in turn and displayed. Therefore, in the third evacuation guidance system, as in the first evacuation guidance system, even if an evacuation route set excluding an inaccessible road due to the occurrence of a disaster is displayed, the third evacuation guidance system is safe through the evacuation route. It is difficult to guide the evacuation site quickly and smoothly, and there is a problem that the installation cost becomes too high due to the necessity to install many guide plates.

  Furthermore, the first and second evacuation guidance systems have significant problems in common with each other. In other words, a large number of evacuation guidance devices or guidance plates are inevitably installed in places where a large number of residents come and go, that is, where there is a possibility of being damaged in the event of a large-scale disaster. Therefore, when a large-scale disaster occurs, some of them are damaged and become non-functional, and there is a possibility that evacuation guidance cannot be performed. In addition, in a disaster countermeasure system such as an evacuation guidance system, there is a possibility of a power failure when a disaster occurs, so a power failure response device such as a generator or a backup battery is generally attached. However, in the first and second evacuation guidance systems, it is necessary to provide a power failure response device for each of a large number of evacuation guidance devices or guidance guide plates, so that the installation cost is further increased.

  The present invention has been made in view of the above-mentioned problems, and is a safe structure selected according to the damage situation even in a wide target area, while being inexpensive enough to perform simple control over a simple structure. It is an object of the present invention to provide an evacuation guidance system using a light beam that can be guided quickly and smoothly to a safe evacuation place through an evacuation route set by connecting only roads.

  In order to achieve the above object, an evacuation guidance system using light beams according to the invention of claim 1 includes a light radiation device installed at a high place overlooking almost the entire target area to be evacuated. A light source for emitting radiation consisting of a linear light beam that can be seen day and night, and the light source for light emission is arranged so as to emit the light beam for guidance from a light radiation port that is open at one end of the cylindrical body. An exterior cylinder body that is rotatably supported so as to be able to project a guide light beam radiated from the light beam emission opening in an arbitrary direction, and the exterior cylinder body is rotated so that the guide light beam is directed in a predetermined direction. Evacuates guide beam projected on each road of the evacuation route set by connecting the necessary roads to reach the evacuation place set in advance in the target area and the beam radiation direction variable mechanism to drive For the place Is characterized in that the light radiation direction changing mechanism is configured to include a controller for controlling drive to the optical scanning while along the evacuation route direction.

  The evacuation guidance system according to the invention of claim 2 is the evacuation guidance system according to claim 1, wherein the light source for light emission is a xenon lamp, and the light of the discharge lamp with respect to the discharge lamp. A reflecting mirror that is provided in a relative arrangement in which the diverging part and the focal point of the light source coincide with each other and reflects light emitted from the discharge lamp by a bowl-shaped reflecting surface to change the light into a parallel light beam toward the light emitting port; The outer cylindrical body is supported by a support base so as to be rotatable about a vertical direction with a pivotal support as a fulcrum, and the support base is fixed on a rotary plate that rotates about a horizontal direction and is rotated about a horizontal direction. A vertically rotating motor that is rotatably provided and that rotates the exterior cylinder body around the vertical direction via the rotation support shaft, and the exterior cylinder body via the rotation plate and the support base. Around the horizontal direction A horizontal rotation motor for rotationally driving is provided, and the controller derives the rotation direction and rotation angle of each of the vertical rotation motor and the horizontal rotation motor corresponding to the set evacuation route. It is characterized in that the guide light beam is scanned along the evacuation route by controlling the rotation based on the light emission direction control data.

The evacuation guidance system by the light beam of the invention according to claim 3 is the evacuation guidance system according to claim 1 or 2, wherein an evacuation guidance command device for remotely controlling the radiation direction of the guide beam of the light radiation device is installed. The evacuation guidance command device has a data input unit for manually entering data such as a start command and road damage information accompanying the occurrence of a disaster when a disaster occurs, In the city area topographical information, which is information on the topography of all roads with a road width greater than or equal to the predetermined value existing in the road, connecting the required roads to reach the evacuation site in the shortest distance, By connecting each desired road so that the evacuation route and some roads of this regular evacuation route can be changed to various other roads to reach the evacuation site The evacuation route information including the type of changed evacuation route and the evacuation route information are stored in association with each evacuation route individually, and light beams are directed toward the evacuation site for a plurality of roads constituting each evacuation route. The rotation direction and the rotation angle of each of the vertical direction rotation motor and the horizontal direction rotation motor for variably controlling the radiation direction of the light beam so as to be sequentially projected and scanned can be synchronized with each other. Based on the storage unit in which the light radiation direction control data arranged in series is stored in advance and the road damage information and the urban area terrain information read from the storage unit when the road damage information is input from the data input unit After specifying the evacuation route, the light emission direction control data corresponding to the evacuation route is read from the storage unit and transmitted to the light emission device. It is constituted by a control unit for.

  According to the evacuation guidance system using light rays according to claim 1, a guide light beam that is a linear light beam that can be visually recognized regardless of day or night is radiated from a light radiation device installed at a high place overlooking the entire target area to be evacuated. Since this light beam is projected on each road of the evacuation route and scanned along the evacuation route in the direction toward the evacuation route, a person in any location in the target area can The guide beam projected toward the evacuation route is always visually recognized without losing sight, and is moved while being guided in the scanning direction of the guide beam. It can be guided quickly and smoothly. Therefore, in this evacuation guidance system using light, unlike the conventional evacuation guidance system, it is different from the one that has to understand the evacuation route by stopping and confirming the display contents of many display devices for guided evacuation each time. Because the guiding beam is projected from a high place, it is guided by the guiding beam that can always be seen by simply looking up at any place in the target area, so it loses normality and panics due to the occurrence of a disaster. Even a person who has little knowledge of the geography around the disaster occurrence area, such as a person who has become a traveler or a traveler, can be surely guided to a safe evacuation site.

  In addition, unlike the conventional system where a large number of evacuation guidance devices or individual guidance guide plates need to be provided with a power failure response device, a high place overlooking the entire target area where the light radiation device should be evacuated. By installing it in a relatively wide target area, guidance along the evacuation route set in a relatively large target area can be handled with a very simple configuration that only installs a single light emitting device. Since the device only needs to be attached to a single light emitting device, the installation cost is significantly reduced. In addition, an external cylindrical body in which the light emitting light source in the single light emitting device is arranged so as to emit the guiding light from the light emitting port is rotatably provided so that the guiding light is directed in an arbitrary direction. In addition, there is provided a light radiation direction variable mechanism that rotates the outer cylindrical body so that the guide light beam is directed in a predetermined direction. The light beam radiation direction variable mechanism is scanned along the evacuation route by control of the controller. Therefore, it is only necessary to perform simple control to control the individual evacuation systems, so that each display device is individually controlled based on the information transmitted from the disaster countermeasure center to each evacuation guidance display device as in the conventional guided evacuation system. The control is much simpler than that in which complicated control for displaying the evacuation route on the guidance map is performed, and the running cost can be further reduced accordingly.

According to the evacuation guidance system using light rays according to claim 2, the light source for light emission is provided in a relative arrangement in which the discharge lamp composed of a xenon lamp and the light divergence portion thereof and the focal point of the discharge lamp coincide with each other. Because it is composed of a reflecting mirror that reflects the light emitted from the discharge lamp by a bowl-shaped reflecting surface and changes it to a parallel light beam that goes to the light emission port, it can be visually recognized regardless of day and night, In addition, it is possible to easily radiate a guide light beam that is a linear light beam that can be projected to a distance of about 10 km with the light beams in parallel. In addition, as a beam radiation direction variable mechanism, a vertical rotation motor that rotates a support base that rotates the outer cylindrical body so as to rotate freely in the vertical direction, and a support base that rotates in the horizontal direction. Since there is a rotating plate that freely supports and a horizontal rotation motor that rotates the outer cylinder around the horizontal direction via a support base, the outer cylinder is directed to the guide beam in any direction. It can be pivotably supported so that it can project. Furthermore, the controller controls the rotation and rotation angle of each of the vertical rotation motor and the horizontal rotation motor based on the light emission direction control data. It is possible to change the guide light beam so as to be directed in a predetermined direction only by performing the operation, and the guide light beam can be accurately scanned along the evacuation route.

  According to the evacuation guidance system using light rays according to claim 3, since the local disaster countermeasure center that reads the light radiation direction control data corresponding to the evacuation route from the storage unit and transmits it to the light radiation device is provided, the damage caused by the disaster If some of the roads that make up the evacuation route become inaccessible due to changes in the situation and it becomes necessary to change the evacuation route, the regional disaster countermeasure center will provide information on urban topography and road damage information about the inaccessible road. The modified evacuation route having the shortest distance is derived based on the data, and the light radiation direction control data stored in advance in the storage unit in association with the changed evacuation route is read from the storage unit and transmitted to a single light emitting device. By doing so, the beam radiation direction control data can be updated and set, so the disaster countermeasure center like the conventional evacuation guidance system. Each evacuation guidance device that received the received disaster occurrence location identification information determines the optimum evacuation location based on the received disaster occurrence location identification information, map information, location information of the evacuation location, and current location information on the guidance map. Control data that accompanies changes in disaster information compared to those that perform complex control to identify and search the evacuation route to the identified evacuation site based on map information and then display this evacuation route on the guide map The renewal setting can be performed remarkably quickly and accurately.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an overall configuration of a light beam emitting device 1 in a light beam evacuation guidance system according to an embodiment of the present invention. The light beam radiating device 1 and a regional disaster countermeasure center described later use a light beam evacuation guidance system. Is configured. The configuration of the light emitting device 1 is broadly divided into a light emitting device main body 2 that emits light, an operation control mechanism 3 of the light emitting device main body 2, and a light emitting direction to be described later transmitted from the regional disaster countermeasure center. A receiving device 4 that receives control data, a light emitting device main body 2, an operation control mechanism 3, and a power supply device 7 that supplies driving power to the receiving device 4 are configured.

2 which is a cut side view of the light emitting device main body 2 and FIG. 3 which is a front view thereof, the light emitting device main body 2 includes a discharge lamp 9 and a reflecting mirror 10 inside a cylindrical outer cylindrical body 8. One end of the outer cylinder 8 is opened to provide a light emission port 11. More specifically, a discharge lamp 9 that emits a strong light beam is provided in the interior central portion of the exterior cylindrical body 8 in an arrangement along the cylindrical center of the exterior cylindrical body 8, and the reflecting mirror 10. However, it is provided in such an arrangement that the emitted light from the discharge lamp 9 is reflected by the reflecting surface 10a made of a bowl-shaped inner peripheral surface and radiated from the light emitting port 11 of the outer cylindrical body 8. The reflecting surface 10a of the reflecting mirror 10 is formed in a parabolic shape, and a relatively large-diameter through-hole 10b that serves also for introducing cooling air is opened at the center.

  As the discharge lamp 9, in this embodiment, a xenon lamp using light by arc discharge in xenon gas is used. The discharge lamp 9 is disposed so as to penetrate the through-hole 10b of the reflecting mirror 10, and one end portion near the light emitting port 11 is fixed to the inner surface of the outer cylindrical body 8 via three support rods 12. The other end is fixed to the inner surface of the outer cylindrical body 8 via the mounting arm 13, the insulating plate 14 made of bakelite, and the support arm 17. As shown in FIG. 2, the discharge lamp 9 and the reflecting mirror 10 are positioned and arranged in a relative relationship in which the light divergence portion of the discharge lamp 9 matches the focal point of the reflecting mirror 10. Are reflected by the reflecting surface 10a of the reflecting mirror 10 and are changed to parallel rays directed toward the light emission port 11. As a result, the light emission port 11 generates a guiding light beam that is a strong straight ray that can be easily recognized. As it spreads less, it radiates far. According to the measurement results, in the case of the discharge lamp 9 composed of a xenon lamp with an output of 2 kW, the light spread in front of 1 km is only 35 m, and if the discharge lamp 9 with a higher output is used, the guide light beam can reach 10 km ahead. It has been confirmed that projection is possible. Further, a control box 18 having a built-in lamp driving circuit for lighting the discharge lamp 9 is fixed to the lower portion of the outer surface of the outer cylinder 8.

  The outer cylindrical body 8 in which the discharge lamp 9 and the reflecting mirror 10 are installed as described above has a substantially U-shaped support in which a pair of support legs 19b and 19c positioned on the left and right on the base plate portion 19a are erected. Supported by the base 19. Specifically, as shown in FIG. 3, a pair of rotational support shafts 20 projecting radially outward at two positions opposite to each other on the radial direction passing through the horizontal plane on the outer surface of the exterior cylinder 8, 20 is provided integrally with the outer cylindrical body 8, and the pivot shafts 20 and 20 are rotatably supported by bearings 21 and 21 provided at the upper ends of the support legs 19b and 19c. Thus, the outer cylinder 8 is supported so as to be rotatable in the vertical direction with the pivotal support shafts 20 and 20 as fulcrums, and the vertical direction of the guiding light beam emitted from the discharge lamp 9 and radiated from the light radiation port 11 is supported. The radiation angle around the direction can be varied.

  Further, one of the pair (left side in FIG. 3) of the support leg portion 19b is bent at a right angle as clearly shown in FIG. 1, and has a mounting plate portion 22a and a support plate portion 22b on both sides of the bending line. A mounting plate portion 22a of the integrally formed motor mounting plate 22 is fixed by a plurality of screw bodies 24 shown in FIG. 3, and a vertical rotation motor 27 of the outer cylinder 8 is provided on the support plate portion 22b. The one rotation support shaft 20 inserted through the insertion hole 22aa of the attachment plate portion 22a is attached in a state of being connected to its own motor shaft. As a result, the exterior cylinder 8 is rotated in the vertical direction about the rotation support shafts 20, 20 by the rotation of the vertical rotation motor 27, and is radiated from the discharge lamp 9 through the light emission port 11. The radiation angle around the vertical direction of the guide beam is variably adjusted.

As shown in FIG. 1, the light emitting device main body 2 has a base plate portion 19 a in a support base 19 provided rotatably on the upper surface of a mounting plate 29 fixed on the mounting base 28 of the operation control mechanism 3. By being fixed on the driven pulley 30 in a state of being placed on the upper surface thereof, the driven pulley 30 is attached to the driven pulley 30 so as to be rotatable around the horizontal direction via the driven pulley 30. Further, a horizontal rotation motor 31 of the light emitting device main body 2 is fixed on the mounting base 28 in such a manner that its motor shaft (not shown) is oriented in the vertical direction. On the motor 31, a driving pulley 32 is provided in a state where the pulley shaft 32 a is coupled to the motor shaft of the horizontal rotation motor 31. A timing belt 33 is wound around the driving pulley 32 and the driven pulley 30.

  As a result, when the horizontal rotation motor 31 is rotationally driven, the rotation of the driving pulley 32 that rotates integrally with the horizontal rotation motor 31 is transmitted to the driven pulley 30 via the driving of the timing belt 33. The outer cylindrical body 8 is rotated in the horizontal direction through the support base 19 that is rotated integrally with the driven pulley 30, and the guide light beam emitted from the discharge lamp 9 through the light beam emission port 11. The radiation angle around the horizontal direction can be variably adjusted. As the vertical rotation motor 27 and the horizontal rotation motor 31, step motors that rotate so as to advance the step by the number of input pulses are adopted, and thereby the rotation angles of both the rotation motors 27 and 31 are changed. It can be controlled accurately according to the control data.

  The controller 34 installed on the mounting base 28 in the operation control mechanism 3 includes a vertical direction rotation motor 27 and a horizontal direction rotation based on the beam radiation direction control data received by the receiving device 4 from a regional disaster countermeasure center described later. Drive control is performed while synchronizing the rotation angle and rotation direction of each motor 31. Therefore, the controller 34 has built-in motor drivers for both the rotating motors 27 and 31. As a result, the guiding light beam emitted from the discharge lamp 9 and emitted from the light beam emission port 11 is scanned along the evacuation route accurately while projecting the set evacuation route. Further, the controller 34 drives and controls the lighting of the discharge lamp 9 via a later-described lamp driving circuit built in the control box 18. On the other hand, the receiving device 4 includes a receiving antenna 37 and a receiving circuit unit 38 that supplies control data received by the receiving antenna 37 to the controller 34.

  A power supply device 7 for supplying driving power to each part of the light emitting device 1 has a built-in DC generator (not shown) having a self-generating function. Via the controller 34, the receiving circuit unit 38, the control box 18 and the like in the light emitting device 1. Therefore, the light emitting device 1 can follow the evacuation route in which the guide light is set by receiving the driving power from the power supply device 7 without any trouble even in the case of a power failure that easily occurs in a large-scale disaster. Can continue scanning. In addition, this power supply device 7 can also use a commercial alternating current power supply instead of the direct current generator of the embodiment.

  FIG. 5 is an explanatory diagram conceptually showing a state in which the evacuation guidance system using light rays according to the present invention is installed and actually operated. The light emitting device 1 of FIG. 1 is a high place that can overlook almost the entire target area designated in advance as an area where a local inhabitant should be guided to a safe evacuation site 50 in the event of a disaster, that is, the light emitted from the light emitting device 1. Is installed in a place where it can be projected over the entire target area. In this embodiment, the case where the light emitting device 1 is installed on the top of a small high mountain is illustrated, but the installation location may be a location that can overlook almost the entire target area, for example, a rooftop of a high building. . The guiding beam emitted from the beam emitting device 1 is a strong linear beam that can be easily seen even in the daytime, and can be projected up to 10 km as described above by using parallel light. Are sequentially scanned in the direction of evacuation for each road constituting the evacuation route set. Therefore, a person in the target area can safely and quickly reach the evacuation site 50 by moving in accordance with the scanning direction of the guide beam. The evacuation place 50 is set in advance to a safe high place even when a tsunami hits, and the evacuation route is set to a route from a lowland such as the seaside 51 to the evacuation place 50.

In this evacuation guidance system using light rays, as described above, the light emitting device 1 is installed at a high place overlooking almost the entire target area to be evacuated, so that the evacuation set within a relatively wide target area. When performing guidance along the route, it is sufficient to install only a single light emitting device 1, but a plurality of the same light emitting devices 1 are provided, and the plurality of light emitting devices 1 are There is an evacuation route in which each of these guiding light beams can be interlocked so as to continuously perform optical scanning at a short predetermined time interval along the same evacuation route, or an evacuation route that can reach the predetermined evacuation site 50 safely and quickly. In the case where a plurality of cases are conceived, the reliability of the evacuation guidance can be remarkably improved if the individual light emitting devices 1 are assigned to the respective light scannings for the respective evacuation routes.

  In FIG. 4 which shows the block diagram of the whole structure of the evacuation guidance system by the light beam of embodiment, in this evacuation guidance system by a light beam, the people in the said area at the time of the disaster occurrence in the said target area are set as safe evacuation beforehand. For example, a regional disaster countermeasure center 40 installed in a public facility for the purpose of conducting work for guiding to the place 50 (FIG. 5) and a high place overlooking the entire target area as described in FIG. The light emitting device 1 is configured.

  The regional disaster countermeasure center 40 is provided with an evacuation guidance command device. This evacuation guidance command device is a data input for manually inputting information such as a start command and road damage information accompanying the occurrence of a disaster when a disaster occurs. Unit 41, a storage unit 43 in which urban landform information, evacuation route information and light radiation direction control data are stored in advance, and a microcomputer, and when a start command is input from data input unit 41, transmission circuit unit 44 is The activation command signal is transmitted from the transmission antenna 47 via the data input unit 41 and the evacuation route is specified based on the road damage information input from the data input unit 41 and the urban area terrain information read from the storage unit 43. The light emission direction control data stored in the storage unit 43 in association with each other is read from the storage unit 43, and this light emission is performed. It is constituted by a control unit 42 for controlling to transmit toward the light emitting device 1 from the transmission antenna 47 of the direction control data by the drive control of the transmission circuit unit 44.

  The urban area terrain information is information relating to terrain mainly composed of all roads having a road width equal to or greater than a predetermined value existing in the target area. The evacuation route information includes a regular evacuation route set by connecting necessary roads so that the evacuation site 50 can be reached in the shortest distance, and a part of the roads of the regular evacuation route as other various roads. And a plurality of types of modified evacuation routes formed by connecting desired roads so that the evacuation site 50 can be reached. The light radiation direction control data is stored in association with each evacuation route in the evacuation route information, and is directed to the direction toward the evacuation site 50 with respect to a plurality of roads constituting the corresponding evacuation route. The rotation direction and the rotation angle of each of the vertical rotation motor 27 and the horizontal rotation motor 31 for variably controlling the radiation direction of the guide light beam from the light projection port 11 so that the guide light beam can be scanned. They are arranged in time series while synchronizing with each other. The light emission direction control data is obtained by following the evacuation route in a state in which the guide light emitted from the light emission port 11 of the light emission device 1 fixed at a predetermined position is actually projected on each evacuation route. The experiment was performed by scanning each direction toward the evacuation site 50 and recording the rotation direction and rotation angle of each of the vertical rotation motor 27 and the horizontal rotation motor 31 that change with the passage of time. Was obtained.

  On the other hand, the light beam emitting device 1 receives the activation command signal and the light radiation direction control data transmitted from the regional disaster countermeasure center 40 via the reception antenna 37, and the activation command signal from the reception circuit unit 38. After the power is supplied from the power supply device 7 to each part of the light emitting device 1, the discharge lamp 9 is driven to turn on via the lamp driving circuit 49, and the light emission direction control input from the receiving circuit unit 38 is controlled. After the data is temporarily stored in the buffer memory 48 and set, the rotation direction and the rotation angle of each of the vertical rotation motor 27 and the horizontal rotation motor 31 are controlled based on the set light emission direction control data. The controller 34 is provided.

  Next, the operation of the evacuation guidance system using light rays will be described in detail with reference to FIGS. First, in FIG. 6, which is a flowchart showing operation control by the control unit 42 of the regional disaster countermeasure center 40, a disaster such as a large-scale fire or earthquake and a tsunami accompanying this earthquake occurs in the regional disaster prevention center 40. When it is determined that it is necessary to guide people in the area to evacuate to the safe evacuation site 50 (FIG. 5), the data input unit 41 is manually operated and an activation command is input to the control unit 42. As a result, the control unit 42 determines that the activation command has been input (step S1), and transmits the activation command signal read from the storage unit 43 from the transmission antenna 47 by driving the transmission circuit unit 44 (step S2). After that, it is determined whether road damage information has been input (step S3).

  The road damage information will be described. At the regional disaster countermeasure center 40, for example, when the state of damage caused by the occurrence of a disaster is reported from a fire department or a police station, etc., based on the reported fire occurrence place or the collapse place such as a road or a building. After identifying a road that is considered to be incapable of safe passage, road damage information related to the identified road is input to the control unit 42 by manual operation of the data input unit 41.

  When it is determined that the road damage information has not been input (step S3), the control unit 42 temporarily stores the regular evacuation route that can reach the evacuation site 50 with the shortest distance in the built-in memory. (Step S4), the light radiation direction control data stored in association with the set regular evacuation route is read from the storage unit 43 and temporarily stored in the built-in memory (step S5). Subsequently, the control unit 42 transmits the light radiation direction control data temporarily stored from the transmission antenna 47 by driving the transmission circuit unit 44 (step S6), and determines whether or not the road damage information being input has changed. (Step S7). The change in this case is when the road damage information is newly input because it is determined in step S3 that no road damage information has been input.

  In the evacuation guidance system of this embodiment, as shown in FIG. 5, the regional disaster countermeasure center 40 is installed in a public facility in a lowland, and the light emitting device 1 can overlook the entire target area to be evacuated. Therefore, the regional disaster countermeasure center 40 transmits the radiation direction control data derived based on the presence or absence of input of road damage information to the transmitting antenna 47. To the reception antenna 37 of the regional disaster countermeasure center 40. However, in the case where the regional disaster countermeasure center 40 is installed in a building built at a high place such as on a mountain and the light emitting device 1 is installed on the roof of this building, the light beam derived from the regional disaster countermeasure center 40 is used. The radiation direction control data may be directly input to the light emitting device 1 by manual operation.

  When it is determined that the road damage information is not newly input (step S7), the control unit 42 determines whether or not an operation stop command is input from the data input unit 41 (step S8), and there is no command input. If it is discriminated, the process returns to step S6 to continue the transmission of the radiation direction control data temporarily stored in the built-in memory (step S6), and until it is discriminated that the operation stop command has been inputted, step S6 to step S8. The operation control of the routine is repeated, and the transmission of the radiation direction control data temporarily stored in the built-in memory (step S6) is continued. When it is determined that the operation stop command is input from the data input unit 41 (step S8), the control unit 42 shuts off the power supply to each unit and stops the operation (step S9).

On the other hand, when it is determined that road damage information has been input (step S3), the control unit 42 reads out the urban area terrain information from the storage unit 43, temporarily stores it in the internal memory, and then inputs this urban area terrain information. Based on the road damage information, a modified evacuation route having the shortest distance is derived, and this modified evacuation route is temporarily stored in the built-in memory and set (step S10). More specifically, as described above, the microcomputer built in the control unit 42 detects the remaining roads other than the inaccessible roads indicated in the road damage information from the roads included in the urban landform information. A control process for deriving a modified evacuation route that can reach the evacuation site 50 with the shortest distance by connecting a required road is performed, and the derived modified evacuation route is temporarily stored in the built-in memory and set. Subsequently, the control unit 42 reads the light radiation direction control data stored in the storage unit 43 in association with the set changed evacuation route from the storage unit 43 (step S11), and transmits the light radiation direction control data to the transmission circuit. Transmission is performed from the transmission antenna 47 toward the light emitting device 1 by the drive control of the unit 44 (step S6).

  Subsequently, the control unit determines whether or not the content of the road damage information input from the data input unit 41 has changed (step S7), and an operation stop command is input when the determination result is unchanged. Whether or not (step S8). At this time, the control unit 42 determines whether either the content of the road damage information being input has changed or an operation stop command has been input (steps S7 and S8). The transmission control of the radiation direction control data temporarily stored in the built-in memory is continued (step S6).

  On the other hand, when the damage content of the road damage information input from the data input unit 41 changes in accordance with the change of the road damage state, the control unit 42 determines that the road damage information being input has changed ( In step S7), the process returns to step S10, and the microcomputer built in the control unit 42 is indicated in the road damage information newly input from each road included in the urban area terrain information temporarily stored in its own internal memory. After the control process for newly deriving a modified evacuation route that can reach the evacuation site 50 in the shortest distance by connecting the required roads among the remaining roads except for the inaccessible road, the derived change By temporarily storing the evacuation route in the built-in memory, the changed evacuation route being stored is updated and set.

  Subsequently, the control unit 42 reads the light radiation direction control data stored in the storage unit 43 in association with the updated changed evacuation route from the storage unit 43 (step S11), and transmits this light radiation direction control data. Transmission is performed from the transmitting antenna 47 to the light emitting device 1 by drive control of the circuit unit 44 (step S6). Thereafter, the control unit 42 repeats the same control process as described above until the operation is stopped by inputting an operation stop command from the data input unit 41.

  Next, in FIG. 7 which is a flowchart showing the operation control by the controller 34 of the light emitting device 1, the controller 34 waits for the activation command signal to be input from the reception circuit unit 38 (step S21), and then the activation command signal. Is determined to have been input (step S21), driving power is supplied from the power supply device 7 to each part of the light emitting device 1, and then the discharge lamp 9 is driven to light through the lamp driving circuit 49 (step S22). . Next, the controller 34 temporarily stores in the buffer memory 48 and sets the light radiation direction control data input following the start command signal from the receiving circuit unit 38 (step S23). After that, the controller 34 controls the rotation direction and the rotation angle of the vertical direction rotation motor 27 and the horizontal direction rotation motor 31 in synchronization with each other based on the set light radiation direction control data (step S24). .

As described above, the light radiation direction control data is transmitted to the evacuation route in a state where the light emitted from the light radiation port 11 of the light radiation device 1 fixed at a predetermined position is actually projected on each evacuation route. Scan along the direction toward the evacuation site 50 along the way, and record the rotation direction and rotation angle of each of the vertical direction rotation motor 27 and the horizontal direction rotation motor 31 that change with the passage of time at that time. The rotation direction and the rotation angle of each of the vertical direction rotation motor 27 and the horizontal direction rotation motor 31 are arranged in time series while being synchronized with each other. Accordingly, by controlling the rotation direction and the rotation angle of the vertical direction rotation motor 27 and the horizontal direction rotation motor 31 based on the light emission direction control data stored and set in the buffer memory 48, the light is emitted from the light emission port 11. The emitted light is scanned toward the evacuation site 50 while accurately projecting the evacuation route set by the regional disaster countermeasure center 40.

  Subsequently, the controller 34 determines whether or not the content of the light radiation direction control data being input from the receiving circuit unit 38 has changed (step S25), and if the determination result shows no change, the receiving circuit unit 38 has. It is determined whether or not an operation stop command signal has been input (step S26). At this time, the controller 34 determines whether either the content of the light radiation direction control data being input has changed or the operation stop command signal has been input (steps S25 to S26). The control of the rotation direction and the rotation angle of each of the vertical direction rotation motor 27 and the horizontal direction rotation motor 31 based on the beam radiation direction control data being temporarily stored in the buffer memory 48 and being set is repeated. (Step S24) is continued. Thereby, the scanning of the guide beam along the evacuation route set in the regional disaster countermeasure center 40 is repeated. Then, when the controller 34 determines that the operation stop signal is input from the receiving circuit unit 38 (step S26), the controller 34 cuts off the power supply from the power supply device 7 to each part of the light emitting device 1 and Stop operation.

  On the other hand, when the control content of the received light radiation direction control data has changed, the controller 34 determines that the light radiation direction control data being input has changed (step S25), and uses the changed light radiation direction control data. After temporarily storing in the buffer memory 48 and updating the setting of the light radiation direction control data (step S28), the process returns to step S24, and the vertical rotation motor 27 is returned based on the updated light radiation direction control data. The rotation direction and the rotation angle of each of the horizontal rotation motors 31 are controlled in synchronization with each other. As a result, the guiding light beam emitted from the light beam emission port 11 is scanned toward the evacuation site 50 while accurately projecting the newly set evacuation route in accordance with the change of the damage situation in the regional disaster countermeasure center 40. The Thereafter, the controller 34 repeats the same control process as described above until it determines that the operation stop command signal has been input (step S26) and stops the operation (step S27).

  In the above-described evacuation guidance system using light beams, the light radiation device 1 is installed at a high place where the entire target area to be evacuated can be looked at. The light radiation device 1 can be viewed day and night, and the light beams are parallel. Each of the evacuation routes connecting the necessary roads so as to reach the preset evacuation site 50 is radiated as a guide beam composed of a linear beam that can be projected as far as 10 km. Because the light is projected on the road and scanned along the evacuation route in the direction toward the evacuation site 50, even for people in any location in the target area, it is projected for the evacuation route from a high place. By visually confirming without losing sight of the light beam and moving in the scanning direction of the guide light beam, the light beam is quickly and smoothly guided to the safe evacuation site 50 through the evacuation route. Door can be.

  Therefore, in this evacuation guidance system using light rays, the evacuation route is determined by stopping and confirming the display contents of many display devices for guidance evacuation installed at branch points of a plurality of roads as in the conventional guidance system. Unlike what must be understood, the guide beam is projected from a high place, so it can be guided to the evacuation site with the guide beam that can always be seen by simply looking up at any location in the target area. , Even those who have lost their normal feelings due to a disaster and who have become panic mentally conscious and those who have little knowledge of the geography of the area around the disaster are surely guided to a safe evacuation site 50 be able to.

In addition, since the evacuation guidance system using light rays scans the guidance light beam emitted from the light radiation device 1 installed at a high place along the evacuation route, it follows the evacuation route set in a relatively wide target area. When guiding, it is possible to cope with an extremely simple configuration by simply installing a single light emitting device 1, and a display device for evacuation guidance is provided at each branch point of a plurality of roads as in a conventional evacuation guidance system. Installation costs are much cheaper than those.

  In addition, the outer cylindrical body 8 is arranged around the vertical direction and the horizontal direction around the outer cylindrical body 8 in which the light source (discharge lamp 9) for guiding light in the single light emitting device 1 radiates the guiding light from the light emitting port 11. Each of the motors 27 and 31 is provided with a vertical rotation motor 27 and a horizontal rotation motor 31 for rotating the outer cylindrical body 8 about the vertical direction and the horizontal direction. And the rotation angle is controlled based on the light emission direction control data provided corresponding to the set evacuation route, so that the guide beam is scanned along the evacuation route. The evacuation route is displayed on the guidance map individually for each display device based on the information transmitted from the disaster countermeasure center to each evacuation guidance display device. To a control than those performing complex control is much easier, it still costs and running costs also from this point.

  Furthermore, when a part of the road that constitutes the evacuation route becomes inaccessible due to a change in the damage situation due to the disaster, and it becomes necessary to change the evacuation route, the regional disaster countermeasure center 40 cannot pass with the urban landform information. A modified evacuation route that is the shortest distance is derived based on the road damage information related to the road, and the light radiation direction control data stored in the storage unit 43 in advance in association with the changed evacuation route is read from the storage unit 43 and is simply read. Since the beam radiation direction control data is immediately updated and set by transmitting to one beam emitting device 1, the disaster occurrence location identification information transmitted from the disaster countermeasure center is received as in the conventional evacuation guidance system. Each evacuation guidance device receives the disaster location identification information, map information, evacuation site location information, and current location information on the guidance map. Compared to the one that identifies the most suitable evacuation site based on the map, searches the evacuation route to the identified evacuation site based on the map information, and then performs complex control to display this evacuation route on the guide map In addition, it is possible to perform control data update setting accompanying changes in disaster information much more quickly and accurately.

  Note that the present invention is not limited to the above-described embodiment, and various additions, modifications, or deletions are possible within the scope not departing from the gist of the present invention, and such modifications are also included in the scope of the present invention. For example, the guide light is not limited to the light emitted from the discharge lamp 9 composed of the xenon lamp of the embodiment reflected by the reflecting mirror 10 and changed to a parallel light, but is a light source having strong directivity and close to a parallel light, for example, It is also possible to use a laser beam designed to reduce interference so as not to cause damage to the eyes. When the regional disaster countermeasure center 40 is provided in the vicinity of the place where the light emitting device 1 is installed, instead of transmitting the information by wireless communication, the direction of the light radiation newly obtained in the regional disaster countermeasure center 40 The control data may be directly input and updated by manual operation of the data input unit of the light emitting device.
