Description

  The present invention relates to a road visual recognition device with a guidance function that is installed on a structure on or around a road and normally performs the function of a light, and can exhibit a guidance function in an emergency or disaster.

  Roads and sidewalks are being developed as transportation infrastructure in Japan and around the world. Vehicles traveling on such roads and pedestrians walking on sidewalks are less likely to experience difficulties in traveling and walking during the day due to their feet and surrounding environment illuminated by natural light.

  However, natural light naturally decreases at night, which may cause difficulties and difficulties in running and walking. If it is a vehicle, it can maintain a safe driving | running | working even at the night when it became dark by illuminating a road with the illuminating device with which the vehicle itself is equipped. In addition, an outdoor light is installed on the road, or a reflective or light-emitting guide plate is installed, so that the vehicle can travel safely while visually checking the traveling direction and the road.

  On the other hand, when a pedestrian walks on a sidewalk or a road used by both a vehicle and a pedestrian, there is a problem that it becomes difficult to see the sidewalk and the road at night. Outside lights may be installed on roads and sidewalks where pedestrians walk, but in areas and roads where infrastructure is not well maintained, outside lights are often not installed or insufficient. In general, when a pedestrian walks, it is rare to have a flashlight or the like, and it is difficult to illuminate a sidewalk or a road with his / her own means.

  As described above, when a pedestrian travels on a sidewalk or road at night, the safety and security of walking are often not ensured. In recent years, crimes frequently occur on the sidewalks and roads at night, and it is desired that the sidewalks and roads on which the pedestrians walk are sufficiently visible at night.

  In the suburbs and areas with a small population, infrastructure development is difficult to achieve and the necessity is not high. In such areas, there are often no outdoor lights on roads and sidewalks. Also, in the city center and densely populated areas, the installation of outdoor lights may be insufficient on back streets, narrow roads and sidewalks that are not main streets. Under such circumstances, it is difficult to say that the safety and security of pedestrian walking at night are ensured.

  On the road, there are a case where the sidewalk on which the pedestrian walks and a roadway on which the vehicle travels are separated, and a case where the sidewalk and the roadway are not separated. In the former case, since the vehicle does not enter the sidewalk, the pedestrian is less likely to receive danger from the vehicle. However, since the roadway and the sidewalk are separated, there is a problem that it is difficult for the light from the outside lights installed for vehicles on the roadway to illuminate the sidewalk. Conversely, lighting by the vehicle may cause halation, which may make it difficult for pedestrians to see the feet of the sidewalk and the boundaries of the sidewalk. That is, there is a problem that the safety and security of walking of a pedestrian walking on the sidewalk is low.

  On the other hand, in the latter case, since the boundary between the roadway and the sidewalk is ambiguous, the pedestrian must always walk while feeling the danger from the vehicle. This is the same not only for pedestrians but also for those with weak traffic traveling on light vehicles (such as bicycles). In addition, roads where the roadway and the sidewalk are not clearly separated are often narrow streets and back streets, and of course there is no installation of outdoor lights, and no light from neighboring buildings can be expected. For pedestrians, there are situations where it is difficult to visually recognize the feet and surroundings. Conversely, for vehicles, the pedestrians think that they are walking on the edge of the road, but the pedestrian who lost sight of the road boundary jumps out in the middle of the road, taking into account the safety of pedestrians, etc. There is also a problem that it is difficult to guarantee proper driving.

  Under such circumstances, it is considered necessary to install many outdoor lights on various roads in order to realize safety and security for pedestrians and vehicles.

  However, roads are in various places and their total length is very large. Since there is a demand for reducing power consumption from the viewpoint of global environmental protection in recent years, increasing the number of outdoor lamps that consume power also has a problem that it is difficult to obtain social understanding. Furthermore, if there are too many outdoor lights, extra lighting will increase in spite of the nighttime, which may have an adverse effect on the ecosystem and the living environment.

  For this reason, there is a demand for ensuring safe and secure walking of pedestrians and the like on the road without increasing power consumption. As an example of realizing such a purpose, a line is drawn with a luminous paint at the boundary between the roadway and the sidewalk, or a reflector is installed at the boundary between the sidewalk. However, these measures are not sufficiently visible from pedestrians and vehicles at night, and are far from ensuring safe and secure walking.

  Under such circumstances, it is desired to realize roads and sidewalks that can ensure the safety and security of pedestrians and vehicles.

  In addition, not only can pedestrians walk safely in normal conditions on sidewalks and roadways (hereinafter collectively referred to as “roads”), but they can also walk safely to destinations and evacuation areas during emergencies and disasters. There is also a need for a guidance function that can be used.

  That is, in modern society, (1) ensuring safety and security during normal walking (normal state) on the road, and (2) prompt and reliable guidance in the event of an emergency or disaster (emergency state). However, it is demanded on the road. In such a situation, various techniques have been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

JP 2005-163274 A JP 2003-268732 A JP 2005-31846 A

  Japanese Patent Laid-Open No. 2004-260688 reliably performs evacuation guidance at the time of an earthquake at night with a small amount of light by causing the light emitting section 1 to emit light and introducing light into the light guide plate 2 to cause the large area guiding display section 3 to emit light. In addition, a self-luminous guidance device capable of holding the guidance function for a long time while suppressing the amount of power consumed when the guidance light emitter 1 emits light is disclosed.

  Patent document 1 is provided with a solar cell, a guide light, and a seismic intensity sensor, and aims at guiding a pedestrian or the like when an earthquake occurs by causing the seismic intensity sensor to emit a guide light when an earthquake occurs.

  However, the guidance device disclosed in Patent Document 1 is a pillar-type guidance device that is installed on a road by a pillar so that a guide light is visually recognized at a certain height. There is an advantage that the guide light can easily enter the pedestrian's eyes because the guide light has a certain height by the support.

  However, since it is a pillar type, there is a high possibility that it will collapse or break down at the time of a disaster such as an actual earthquake, and there is a risk that guidance cannot be realized in an emergency or disaster. Moreover, since it is a support | pillar type, naturally installation cost also starts, and there also exists a problem which cannot be installed in many roads. As with outdoor lights, the guidance device needs to be installed on various roads, but if the installation cost is high, this need cannot be met.

  In addition, it is necessary to obtain a construction permit for installation on the road because it is a column type. There are various public institutions that manage roads, and it is extremely difficult to obtain a construction permit for installation. In addition to this, the guidance device of Patent Document 1 has a problem that it is difficult to realize guidance with a wide range and high versatility.

  In addition, there is a problem of not having a function for realizing safety and security of pedestrians and the like in a normal state other than in an emergency or disaster. This is because the function of assisting the visual recognition of the sidewalk and the roadway is insufficient.

  Patent Document 2 discloses a road light-emitting device including a case, a light-emitting element attached to the case, a blinking control circuit for blinking the light-emitting element, and a power source battery. A road light-emitting device is disclosed that is electrically connected to a blinking control circuit and receives a radio wave instructing matching blinking so that blinking of the light-emitting elements is matched.

  Patent Document 2 is intended to make it easier to visually recognize the boundary of a sidewalk on a road, etc. by performing flashing light emission while being installed on a curb of a road as a kind of unit, unlike the column type of Patent Document 1. It is said.

  However, the light-emitting device for roads of Patent Document 2 is intended to be installed on a curbstone or the like, and all is exposed on the surface at the boundary between the roadway and the sidewalk. For this reason, there is also a problem of failure or damage due to a collision with a pedestrian or a vehicle. It also has problems such as mischief and theft.

  Further, since the boundary between the roadway and the sidewalk can be visually recognized by matching the flashing light emission, it is useful for visual recognition for the vehicle, but is insufficient for visual recognition for the pedestrian. In addition, when a failure or the like occurs in some of the plurality of light emitting devices installed, the flashing light emission cannot be matched, and an unnatural flashing light emission occurs. If such an unnatural flashing light emission occurs on the road, there is a possibility that a vehicle or a pedestrian will be misled and cause an accident.

  In addition, Patent Document 2 has a problem that it can cope with visual recognition in a normal state but cannot cope with appropriate guidance of a pedestrian or the like in an emergency state.

  Patent Document 3 discloses a plurality of guide members in which a special pattern indicating position information is arranged, an imaging function for capturing a special pattern each time a pedestrian passes through each guide member, and a position of the special pattern from the captured image. A first walking assistance member having a communication function for reading and transmitting information, and detecting the current position of the pedestrian based on the position information transmitted from the first walking assistance member, and guidance information relating to the vicinity thereof And a second walking assisting member having a communication function for receiving guidance information sent from the server, and an output function for outputting the guidance information. A pedestrian guidance system is disclosed.

  Patent Document 3 aims at a system that detects the position of a pedestrian based on a captured image or the like and reliably guides the pedestrian to a destination.

  However, the system of Patent Literature 3 requires a special guide member, an imaging device, a server, and various other devices and devices. For this reason, it becomes a very large-sized apparatus, installation cost and manufacturing cost become large, and it is not realistic. In addition, when a certain pedestrian is targeted, it can be accurately and reliably guided to the destination, but the safety and security of walking in the normal state of an unspecified number of pedestrians cannot be ensured. Naturally, it is difficult to realize guidance in an emergency state for an unspecified number of pedestrians.

  Patent document 3 can only perform special guidance only for specific pedestrians.

  As described above, the conventional techniques including Patent Documents 1 to 3 have the following problems.

  (Problem 1) A simple and low-cost device cannot realize the safety and security of walking of a pedestrian or the like in a normal state.

  (Problem 2) In Problem 1, the safety and security of pedestrians and the like cannot be ensured by easily visually recognizing the road particularly at night when there is no outdoor light.

  (Problem 3) In an emergency, it is not possible to properly guide a large number of unspecified pedestrians in the evacuation direction with safety and security in a normal state.

  (Problem 4) Installation is not possible without the hassle of permission and permission such as installation permission.

  (Problem 5) When a plurality of guidance devices are used, even if a problematic guidance device occurs, it cannot be handled.

  (Problem 6) A simple system that does not require extra power or equipment cannot be assembled.

  In view of these problems, the present invention allows a pedestrian or the like to easily see a road in a normal state while being simple and low-cost, and in an emergency state, allows an unspecified number of pedestrians or the like to be evacuated. An object is to provide a road visual device with a guidance function that can be guided.

  In view of the above problems, a road visual device with a guidance function according to the present invention manages a plurality of light emitting units embedded in and installed on at least one surface of a road, an outdoor public space and an outdoor structure, and a plurality of light emitting units. Each of the plurality of light emitting units emits light based on the power of the solar battery, the storage battery that stores the power generated by the solar power generator, and the power of the storage battery. The light emitting unit, an induction light emitting unit that emits light in a shape pointing in a predetermined direction based on the power of the storage battery, and a wireless communication unit that performs wireless communication with other light emitting units among the plurality of light emitting units.

  The road visual device with a guidance function of the present invention can be realized simply and at low cost. Further, since the light emitting units constituting the apparatus are simply installed or embedded on the road surface, the installation is easy, and there is less time and effort for permission and approval. In addition, there is an advantage that it is easy to avoid failure and damage after installation.

  In addition, the road viewing device with a guidance function according to the present invention can easily make a pedestrian or the like visually recognize a road boundary or the like by emitting light by using solar power as electric power in a normal state. At the same time, in an emergency state, it can be guided in the direction of evacuation.

  Furthermore, the road visual device with a guidance function of the present invention detects a case where a defective light-emitting unit is present among a plurality of light-emitting units installed continuously, and does not leave the problem of the entire device unattended.

  (Embodiment 1)

(Overview)
FIG. 1 is a schematic diagram showing a state in which a road viewing device with a guidance function according to Embodiment 1 of the present invention is installed. The road 100 is divided into a roadway 101 and a sidewalk 102. Thus, the road 100 divided into the roadway 101 and the sidewalk 102 is in many places. FIG. 1 shows a case where the roadway 101 and the sidewalk 102 are clearly separated (for example, the roadway 101 and the sidewalk 102 are separated by a step), but the roadway 101 and the sidewalk 102 are clearly shown. The same applies to the case where the roadway 101 and the sidewalk 102 are not separated from each other (when the roadway 101 and the sidewalk 102 are separated from each other only by lines or when the roadway 101 and the sidewalk 102 are not clearly distinguished).

  A plurality of light emitting units 3 </ b> A to 3 </ b> E are installed at the boundary portion 103 of the sidewalk 102. In FIG. 1, five light emitting units 3 </ b> A to 3 </ b> E are shown for convenience of illustration, but the number of the light emitting units 3 may be any number (it is not necessary to distinguish each of the plurality of hako units). In this case, the light emitting unit 3 will be described as a reference). Further, not only the boundary portion 103 of the sidewalk 102 but also a plurality of light emitting units 3 may be installed on the roadway 101 or the shoulder of the sidewalk 102.

  In addition to the road 100, a plurality of light emitting units 3 may be installed in at least one of an outdoor public space and an outdoor structure. At this time, as shown in FIG. 2A, each of the plurality of light emitting units 3 may be installed on at least one surface of the road 100, the outdoor public space, and the outdoor structure. ), Each of the plurality of light emitting units 3 may be installed so as to be embedded in at least one of the road 100, the outdoor public space, and the outdoor structure. There are various places such as roads, signs, and existing buildings. These may be private or public land.

  FIG. 2 is a side view showing an installation state of the light emitting unit in Embodiment 1 of the present invention. FIG. 2 shows a state where the state of being installed at the boundary portion 103 of the sidewalk 102 as viewed from the side as shown in FIG.

  FIG. 2A shows a state in which a plurality of light emitting units 3 </ b> A to 3 </ b> E are installed on the surface of the boundary portion 103 of the sidewalk 102. FIG. 2B shows a state in which a plurality of light emitting units 3 </ b> A to 3 </ b> E are installed so as to be embedded inside the boundary portion 103 of the sidewalk 102. Although not shown in FIG. 2, as shown in FIG. 2B, it may not be completely embedded but may be embedded by a certain amount.

  As described above, the light emitting unit 3 is easily seen by a pedestrian or a driver by being installed on the boundary portion 103 of the sidewalk 102 or the road shoulder. Further, as will be described later, also in emergency evacuation, the induced light emission by the light emitting unit 3 is easily seen by pedestrians and drivers.

  The road viewing device 1 with a guidance function further includes a base station 2 that manages a plurality of light emitting units 3. The base station 2 manages the whole of the plurality of light emitting units 3 and controls the visual recognition of the road by the light emitting units 3 and the emergency guidance. By comprehensive management of the plurality of light emitting units 3 by the base station 2, in the normal state, the plurality of light emitting units 3 ensure that the sidewalk 102 (or the roadway 101) is visually recognized by pedestrians and drivers, and the emergency state. In this case, it is possible to reliably show the evacuation destination to pedestrians and drivers.

  As described above, the combination of the base station 2 and the plurality of light emitting units 3 and the plurality of light emitting units 3 are installed at appropriate locations, so that a walking area is provided on at least one of the road 100, an outdoor public institution, and an outdoor building. Can be clearly indicated to pedestrians and drivers, and in addition, evacuation can be performed smoothly and reliably by showing evacuation destinations to pedestrians and drivers in emergency situations (such as when a disaster occurs).

  FIG. 3 is a block diagram of the light emitting unit according to Embodiment 1 of the present invention. FIG. 3 shows a state in which the light emitting unit 3 is viewed from above. The shape of the light emitting unit 3 and the arrangement of each element shown in FIG. 3 are examples, and other shapes and arrangements of elements may be provided as long as the same function can be exhibited.

  The light emitting unit 3 includes a solar power generation unit 4, a storage battery 5, a light emitting unit 6, an induction light emitting unit 7, and a wireless communication unit 8.

  The photovoltaic power generation unit 4 generates electric power by generating sunlight. The storage battery 5 stores the electric power generated by the solar power generation unit 4. Thus, by providing the solar power generation unit 4 and the storage battery 5, the light emitting unit 3 can perform self-power generation. That is, it is not necessary to provide a battery that needs to be replaced or charged, or to supply power through the power path. Since the road visual recognition device 1 with a guidance function is required to emit light constantly at night, the self-power generation can eliminate the worry of turning off due to power outage.

  In addition, self power generation can be used to cover the necessary power in the light emitting unit 6 and the induction light emitting unit 7, thereby eliminating the need to connect a power supply path to the light emitting unit 3. For this reason, the several light emission unit 3 can be easily installed in various places. In particular, as shown in FIG. 1 and the like, it is desirable that a plurality of light emitting units 3 be installed on a sidewalk 102 or the like in order to show a walking area.

  Also in this case, since no connection such as a power supply path is required for the light emitting unit 3, many light emitting units 3 can be installed in various places with a high degree of freedom. As a result, it is possible to reliably realize the purpose of the road visual recognition device 1 with a guidance function, such as clearly indicating a walking area or clearly indicating an evacuation destination.

  The light emitting unit 6 emits light using the power of the storage battery 5. By this light emission, even in a dark place at night, a pedestrian or driver can easily and reliably visually recognize the sidewalk 102 or the roadway 101 (or its boundary). As a result, accidents on the road 100 can be prevented.

  The induced light emitting unit 7 emits light in a shape indicating a predetermined direction using the power of the storage battery 5. In FIG. 3, the guide light emitting unit 7 includes a first light emitting member 71 having a bent portion 73 directed in the right direction in FIG. 3 and a second light emitting member 72 having a bent portion 74 directed in the left direction in FIG. 3. doing. When the first light emitting member 71 or the second light emitting member 72 emits light in an emergency state, the evacuation destination can be clearly indicated as indicated by an arrow.

  The wireless communication unit 8 performs wireless communication with other light emitting units 3 among the plurality of light emitting units 3. For example, as shown in FIG. 1, the wireless communication unit 8 included in the light emitting unit 3A performs wireless communication with the adjacent light emitting unit 3B. The wireless communication unit 8 included in the light emitting unit 3B performs wireless communication with the adjacent light emitting unit 3C. The wireless communication unit 8 included in the light emitting unit 3C performs wireless communication with the adjacent light emitting unit 3D. Thus, using the wireless communication unit 8, the plurality of light emitting units 3 perform wireless communication in a daisy chain.

  The wireless communication unit 8 transmits the command signal transmitted from the base station 2 (light emission of the light emitting unit 6, light emission of the induced light emitting unit 7, etc.) to the adjacent light emitting unit 3 when the light emitting unit 3 first receives the command signal. It plays the role of transmitting command signals by connecting the beads.

  One assumption is that the plurality of light emitting units 3 are installed on the road 100. In this case, a plurality of light emitting units 3 are installed over a long distance and a wide range. The base station 2 can transmit a command signal for controlling the light emission of the light emitting unit 6 and the light emission of the induced light emitting unit 7. However, when a plurality of light emitting units 3 are installed over a long distance and over a wide range as described above, it may be difficult to transmit command signals to all the light emitting units 3 only by the base station 2.

  In such a case, the wireless communication unit 8 wirelessly communicates with the wireless communication unit 8 of the adjacent light emitting unit 3 to transmit a command signal, thereby controlling the entire road viewing device 1 with a guidance function within a certain range. It becomes possible.

  Since each of the plurality of light emitting units 3 has the above-described configuration, the road viewing device with a guidance function 1 clearly indicates the walking area by the light emission of the light emitting unit 6 in the normal state, and the guide light emitting unit 7 in the emergency state. The evacuation destination can be clearly indicated by the light emission.

  Next, the details of each part will be described together with the description of the operation.

(base station)
The base station 2 can wirelessly communicate with the light emitting unit 3. The base station 2 transmits a command signal to the light emitting unit 3 by wireless communication. The base station 2 transmits a command signal for causing the light emitting unit 6 of the light emitting unit 3 to emit light in a normal state (a state in which no disaster occurs). Upon receiving this command signal, the light emitting unit 3 causes the light emitting unit 6 to emit light.

  In addition, the base station 2 causes the guide light emitting unit 7 included in the light emitting unit 3 to emit light in an emergency state. At this time, the guide light emitting unit 7 emits light so that the bent portions 73 and 74 directed in the respective directions become a fixed route, like the first light emitting member 71 and the second light emitting member 72. As a result, stimulated light emission is performed along a certain route.

  The base station 2 transmits a command signal instructing the light emitting operation of the plurality of light emitting units 3 in this way.

(Light emitting part)
The light emitting unit 6 emits light based on a command signal from the base station 2. Alternatively, light is emitted based on a command signal from the wireless communication unit 8 of the adjacent light emitting unit 3. FIG. 4 is a schematic diagram of a light emitting unit in which the light emitting unit is illuminated in the first embodiment of the present invention. In FIG. 4, four light emitting units 6 are provided at the four corners of the light emitting unit 3. When the four light emitting units 6 emit light, the four corners of the light emitting unit 3 emit light.

  A plurality of light emitting units 3 that emit light at the four corners are arranged on the road 100, so that a pedestrian or a driver can surely see the walking area. FIG. 5 is a schematic diagram showing a state in which the light emitting units emitting light from the light emitting units in Embodiment 1 of the present invention are arranged.

  As shown in FIG. 5, the light emitting sections 6 at the four corners of the plurality of light emitting units 3 emit light. By arranging such light emitting units 3 continuously, a pedestrian or driver can easily and reliably visually recognize the boundary between the sidewalk 102 and the roadway 101. If a plurality of light emitting units 3 are arranged as shown in FIG. 5, a pedestrian or driver can safely move according to the light train of the light emitting unit 6 of the light emitting unit 3. .

  4 and 5, the mode in which the light emitting unit 3 includes the four light emitting units 6 at the four corners has been described. However, the number of the light emitting units 6, the arrangement positions, and the like may be other modes.

  It is preferable that the light emitting unit 6 emits light when the surroundings have a predetermined brightness or less. For example, it is appropriate to detect light at night or in the evening and emit light. For this reason, it is also preferable that the light emitting unit 3 or the base station 2 is provided with a brightness sensor. At this time, the light emitting unit 6 may emit light based on a command signal from the base station 2 or may autonomously emit light based on detection of lightness by a lightness sensor included in itself.

  The light emitting unit 6 is for clearly grasping the area where pedestrians and vehicles pass, such as the walking area of the road such as the roadway 101 and the sidewalk 102 (in other words, the roadway area). It is preferable to emit light with luminance and chromaticity that are easily visible. For example, it is appropriate that the luminescent color has a bright chromaticity such as yellow or white and high luminance.

  For the same reason, it is also preferable that the light emitting unit 6 blinks at a constant interval or blinks in a predetermined pattern. In addition, when a plurality of light emitting units 6 are provided in one light emitting unit 3 (as shown in FIGS. 4 and 5), the light emitting units 6 may emit light with different chromaticity and luminance. Also in this case, a pedestrian or driver can more easily visually recognize.

  FIG. 6 is a front view of the light emitting unit according to Embodiment 1 of the present invention. FIG. 6 is a drawing corresponding to FIG. 4 but three-dimensionally shown. FIG. 6 also shows that the light emitting unit 3 includes the solar power generation unit 4, the storage battery 5, the light emitting unit 6, and the induced light emitting unit 7 as in FIG. 4.

  FIG. 7 is a side view of the light emitting unit of FIG. 6 as viewed from the side. Similar elements are shown in FIG.

  As can be seen from the light emitting unit 3 shown in FIGS. 6 and 7, the light emitting unit 6 emits light and makes a pedestrian or driver visually recognize a predetermined area of the road 100. Such visual recognition can provide safety and security even on the road 100 at night and without outdoor lights.

(Guide light emitting part)
In the same way as the light emitting unit 6, the induced light emitting unit 7 emits light when the surroundings are below a predetermined brightness. However, the guide light emitting unit 7 is a light emitting element for indicating an evacuation direction on a road where the light emitting unit 3 is installed in an emergency state such as a disaster or an accident. For this reason, it emits light when it receives not only the surrounding lightness but also a command signal including an instruction from the base station 2 to stimulated light emission.

  As shown in FIG. 4 and the like, the guide light emitting unit 7 has a predetermined shape indicating a predetermined direction. In FIG. 4, the 1st light emission member 71 in which the bending part 73 has faced the right direction (it is set as 1st direction), and the 2nd light emitting member 72 in which the bending part 74 has faced in the left direction (it is set as 2nd service). The induction light emitting unit 7 has a shape having a combination of In FIG. 4, the guide light-emitting unit 7 includes a first issuance member 71 having a U-shape and a second light-emitting member 72 having a reverse U-shape.

  When the first light emitting member 71 emits light, the first light emitting member 71 emits light that guides a pedestrian or vehicle in the first direction by the bent portion 73. Conversely, when the second light emitting member 72 emits light, the bent portion 74 indicates light emission that guides a pedestrian or driver in the second direction. Thus, the light emitting unit 3 includes the first light emitting member 71 and the second light emitting member 72 in combination, and the guided light emitting unit 7 includes a walking in both the first direction and the second direction. It can emit light to guide the person.

  Here, the first direction or the second direction serving as the guide direction is an evacuation direction in an emergency state. For example, when a tsunami occurs, the guide light emitting unit 7 emits light indicating the direction away from the tsunami. Alternatively, when an accident or fire occurs, the induced light emitting unit 7 emits light indicating the direction away from the accident or fire.

  FIG. 8 is a front view of the light emitting unit according to Embodiment 11 of the present invention. In FIG. 8, the first light emitting member 71 having the bent portion 73 in the first direction (that is, the shape pointing to the first direction) is shining. In FIG. 8, since the light emitting unit 3 includes two induction light emitting units 7, the first light emitting member 71 also includes two. For this reason, in the light emitting unit 3, the two first light emitting members 71 pointing in the first direction are shining.

  Thus, since the two 1st light emission members 71 are shining so that the 1st direction may be pointed, the some light emission unit 3 will be in the state which is shining, pointing to the 1st direction in a daisy chain.

  As a result, when the first direction is an evacuation destination in an emergency state, the road viewing device with a guidance function 1 can indicate the first direction to the pedestrian or driver as the evacuation destination. A pedestrian or driver who sees light emitted in the first direction can smoothly head for the evacuation destination.

  In order to cause the first light emitting member 71 to emit light so that the first direction is the evacuation destination, the base station 2 outputs a command signal suitable for this. At this time, the command signal transmitted by the base station 2 may be transmitted to the next light emitting unit 3 by the wireless communication unit 8 of the light emitting unit 3.

  FIG. 9 is a front view of the light emitting unit according to Embodiment 1 of the present invention. In FIG. 9, the second light emitting member 72 having the bent portion 74 in the second direction (that is, the shape pointing to the second direction) is shining. In FIG. 9, since the light emitting unit 3 includes two induction light emitting units 7, two second light emitting members 72 are also provided. For this reason, in the light emitting unit 3, the two 2nd light emitting members 72 which point to a 2nd direction are shining.

  Thus, since the two 2nd light emission members 72 are shining so that the 2nd direction may be pointed out, the several light emission unit 3 will be in the state which is shining, pointing to the 2nd direction in a daisy chain.

  As a result, when the second direction is an evacuation destination in an emergency state, the road viewing device with a guidance function 1 can indicate the second direction to the pedestrian or driver as the evacuation destination. A pedestrian or driver who sees light emitted in the second direction can smoothly head for the evacuation destination.

  By having the combination of the 1st light emission member 71 and the 2nd light emission member 72, the guidance light emission part 7 is one light emission unit 3, even if an evacuation direction is a 1st direction or a 2nd direction, The direction of evacuation can be indicated.

  In order to cause the second light emitting member 72 to emit light in order to set the second direction as an evacuation destination, the base station 2 outputs a command signal suitable for this. At this time, the command signal transmitted by the base station 2 may be transmitted to the next light emitting unit 3 by the wireless communication unit 8 of the light emitting unit 3.

(Wireless communication part)
The wireless communication unit 8 can perform transmission / reception of signals with the base station 2 and transmission / reception of signals with the wireless communication unit 8 provided in the adjacent light emitting unit 3. Since the wireless communication with the base station 2 can be performed, the command signal from the base station 2 can be received. Further, since the wireless communication with the adjacent light emitting units 3 can be performed, the command signals can be transmitted in a daisy chain.

  FIG. 10 is a schematic diagram showing a state in which the road viewing device with a guidance function in Embodiment 1 of the present invention is installed. On the road 100, a plurality of light emitting units 3 are installed. At this time, each of the plurality of light emitting units 3 preferably has an identifier. In FIG. 10, the light emitting unit 3A has the identifier [01], the light emitting unit 3B has the identifier [02], the light emitting unit 3C has the identifier [03], and the light emitting unit 3D has the identifier [04] and the light emitting unit 3E has an identifier [05].

  This identifier indicates the order of the light emitting units 3 that are adjacent to each other and gradually move away from the light emitting unit 3 (light emitting unit 3A in FIG. 10) that is closest to the base station 2 (in FIG. 10, light emitting units 3B to 3E). )ing. That is, the order of the plurality of light emitting units 3 with the base station 2 as a reference can be known by the identifier.

  The command signal from the base station 2 is sequentially transmitted to the light emitting unit 3 in the next stage (having the identifier in the next order) by the wireless communication unit 8 in accordance with the order of the identifiers. By sequentially transmitting command signals according to this identifier, all the light emitting units 3 can perform a predetermined operation (light emission of the light emitting unit 6, light emission of the guide light emitting unit 7, etc.).

  As described above, the road visual recognition device 1 with the guidance function according to the first embodiment can make the pedestrian and the driver easily visually recognize the road in a dark time zone such as nighttime, and can provide traffic safety and security. . In addition, in the emergency state, the road viewing device with a guidance function 1 can point either the first direction or the second direction as the evacuation direction and smoothly guide the pedestrian or the like in the evacuation direction.

  The base station 2 may be provided in an organization that performs disaster monitoring, or may be provided at a position that receives an instruction from the organization that performs disaster monitoring. As a result, the base station 2 can transmit a command signal for evacuation immediately in response to the disaster detection at the disaster monitoring organization.

  (Embodiment 2)

  Next, a second embodiment will be described. In the second embodiment, various additional devices of the road visual recognition device with a guidance function 1 described in the first embodiment will be described.

(Relay station)
It is also preferable to have a relay station between a certain light emitting unit 3 and another light emitting unit 3 in a plurality of light emitting units 3 arranged in series. The road viewing device 1 with a guidance function includes a plurality of light emitting units 3. The plurality of light emitting units 3 are installed in various modes and numbers at the place where they are installed. At this time, depending on the case, the distance between a certain light emitting unit 3 and the adjacent light emitting unit 3 may be separated, or communication by the wireless communication unit 8 may be difficult.

  In such a case, by providing a relay station between a certain light emitting unit 3 and the next light emitting unit 3, transmission of command signals between the light emitting units 3 is ensured. In addition, a part of the command signal is not only sequentially transmitted by the wireless communication unit 8, but may be transmitted from the base station 2 to the plurality of light emitting units 3 collectively. Also in this case, when the number of the light emitting units 3 is large or the total extension of the light emitting units 3 is very long, the command signal cannot be transmitted to all the light emitting units 3 only by the base station 2. There is also.

  Even in such a case, the relay station can retransmit the command signal from the base station 2. By this retransmission, the same command signal as the command signal from the base station 2 can be reliably transmitted to the light emitting unit 3 installed before the relay station.

(Display section)
FIG. 11: is a block diagram of the road visual recognition apparatus with a guidance function in Embodiment 2 of this invention. 11 shows a mode in which the base station 2 is further provided with a display unit 21. The display unit 21 may be a part of a personal computer, for example.

  The display unit 21 can display at least one of the position, light emission state, and abnormal state of the plurality of light emitting units 3 to which the identifier is assigned. Each of the plurality of light emitting units 3A to 3E has identifiers [01] to [05]. The base station 2 can confirm and grasp the plurality of light emitting units 3A to 3E with the assigned identifiers. Of course, a command signal can be transmitted according to this identifier.

  The display unit 21 is used, for example, for an administrator who controls the base station 2 to grasp the status of the plurality of light emitting units 3 installed. Since the status of the light emitting unit 3 corresponding to the identifier is displayed on the display unit 21, the administrator can grasp at least one of the positions, light emitting states, and abnormal states of the plurality of light emitting units 3 while viewing this.

  By grasping through the display unit 21, the administrator can grasp the normality / abnormality of the light emitting unit 3 and can immediately take action when there is a problem.

(Monitoring multiple light emitting units)
The road viewing device 1 with a guidance function includes a plurality of light emitting units 3. At this time, the plurality of light emitting units 3 emits light continuously to make a pedestrian or the like visually recognize the road, or continuously cause the light emitting unit 7 to emit light, thereby ensuring that the pedestrian or the like is in the evacuation direction. To induce.

  However, if a failure or malfunction occurs in any one of the plurality of light emitting units 3 installed, there is a problem in that the road cannot be visually recognized and evacuated as described above. For example, there is a case where the wireless communication unit 8 of a certain light emitting unit 3 is out of order and cannot receive a command signal from an adjacent light emitting unit 3, so that the light emitting unit 6 or the guide light emitting unit 7 cannot appropriately emit light. Alternatively, the command signal cannot be transmitted to the next light emitting unit 3 due to a failure of the wireless communication unit 8 of a certain light emitting unit 3.

  If there is a light emitting unit 3 in which such a failure or malfunction has occurred, there is a possibility that it will not be able to perform a sufficient role in either viewing of the road to a pedestrian or the like or guiding in a condemned direction.

  FIG. 12 is a schematic diagram showing monitoring of the light emitting unit in the road viewing device with a guidance function in the second embodiment of the present invention.

  12 includes a base station 2 and a plurality of light emitting units 3 that receive command signals from the base station 2. Each of the plurality of light emitting units 3 has identifiers [001], [002], [003], and [004]. In FIG. 12, an identifier for each light emitting unit 3 is shown as ID: 001.

  The base station 2 transmits a monitoring signal to the light emitting unit 3. At this time, a monitoring signal is transmitted to the light emitting unit 3 having the identifier [001] adjacent to the base station 2. The light emitting unit 3 having the identifier [001] that has received this monitoring signal transmits the monitoring signal to the light emitting unit 3 having the next adjacent identifier [002] via the wireless communication unit 8. Similarly, the light emitting unit 3 having the identifier [003] transmits a monitoring signal to the light emitting unit 3 having the next adjacent identifier [004].

  In this way, the monitoring signal transmitted from the base station 2 is transmitted to the plurality of light emitting units 3 in a daisy chain. This monitoring signal is transmitted at an appropriate frequency such as once every 10 minutes as described in FIG. 12, for example.

  At this time, for example, communication may be interrupted by the light emitting unit 3 having the identifier [003]. That is, the light emitting unit 3 cannot receive the monitoring signal. In this case, the base station 2 determines the light emitting unit 3 having this identifier [003] as a defective light emitting unit. This result is displayed on the display unit 21. By displaying on the display unit 21, the administrator can know the malfunction of the light emitting unit 3 having the identifier [003]. As a result, it is possible to consider measures such as repair.

  Here, not only the light emitting unit 3 having the identifier [003] but also the light emitting units 3 before and after the light emitting unit 3 may be determined as defective light emitting units. At this time, the front and rear light emitting units 3 are also displayed on the display unit 21. Based on these displays, the administrator can confirm the malfunction of the light emitting unit 3. As a result of these, the road visual recognition device with a guidance function 1 can always maintain an accurate operation.

  In addition, the road visual recognition apparatus with a guidance function described in Embodiments 2 and 2 is an example for explaining the gist of the present invention, and includes modifications and alterations without departing from the gist of the present invention.
