  However, when a pedestrian crosses a pedestrian crossing, a sensor detects a pedestrian trying to cross when the pedestrian crosses a pedestrian crossing. It operates so as to illuminate the sidewalk and illuminate the side of the pedestrian crossing. A so-called human sensor is used as the sensor to detect pedestrians etc. in front of the pedestrian crossing and cause the self-luminous roadway to emit light. Therefore, for example, not only pedestrians who are about to cross a pedestrian crossing but also pedestrians who have finished crossing are detected, as well as pedestrians who walk on the sidewalk without crossing the pedestrian crossing. To light up the self-luminous road fence. For this reason, there is a problem in that the road fence may be emitted when it is unnecessary, or the road fence may not be emitted when necessary.

  The present invention solves the above-mentioned problems, accurately detects pedestrians entering a pedestrian crossing, etc., and properly emits light on the roadside, ensuring the pedestrians on the pedestrian crossing to the driver of the car. It is an object of the present invention to provide a self-luminous roadway device for pedestrian crossings that can be recognized by the safety of pedestrians.

A pedestrian detector that detects a pedestrian crossing the pedestrian crossing and the like entering and exiting the pedestrian crossing and outputs a detection signal;
A control means for inputting a detection signal from the pedestrian detector and controlling lighting / flashing of the self-luminous roadway based on the detection signal;
When the pedestrian detector detects that a pedestrian or the like has entered the pedestrian crossing, the control means turns on / flashes the self-luminous road fence and lights up until the pedestrian, etc. exits the pedestrian crossing. Control is performed so as to continue blinking.

  Here, a pedestrian or the like is a concept including a person who uses a pedestrian crossing space, such as a pedestrian, a bicycle, and a wheelchair.

  According to the present invention, when a pedestrian or the like enters a pedestrian crossing, the pedestrian detector detects the pedestrian or the like, and a detection signal is output to the control means. The lighting and blinking continues until the pedestrians cross the pedestrian crossing. As a result, when pedestrians enter the pedestrian crossing, the self-luminous road fence lights up and blinks. Stop and pedestrians can safely cross the pedestrian crossing.

  In addition, the pedestrian detector detects the entry and exit of the pedestrian crossing by pedestrians crossing the pedestrian crossing, so the control means is self-luminous only while the pedestrian crosses the pedestrian crossing. After the road fence is illuminated and pedestrians and the like have crossed the pedestrian crossing, the light can be turned off reliably.

  Here, the self-luminous roadway is provided with a light emitting part for an automobile toward the roadway side, and a light emitting part for a pedestrian is provided toward a pedestrian crossing side. A light emitter that can emit light with different emission colors is provided, and the control means controls lighting and blinking of the automobile light emitting unit and the pedestrian light emitting unit with different emission colors based on the detection signal of the pedestrian detector. It is preferable to configure as described above.

  The pedestrian detector includes a light beam detector that projects a plurality of light beams in front of a pedestrian crossing and detects the entrance and exit of pedestrians by detecting transmission or reflection of the light beams. Can be used.

  The plurality of self-luminous road fences are preferably connected in series to the control means through a single signal line. According to this, a plurality of self-luminous road fences arranged in parallel along the pedestrian crossing can be blinked in synchronization.

  According to the self-luminous roadway device of the present invention, a pedestrian who enters a pedestrian crossing is accurately detected to cause the roadway to emit light appropriately, and the driver of the car is reliably pedestrians on the pedestrian crossing. It can be recognized and the safety of pedestrians and the like can be ensured.

FIG. 1 shows a front view of a self-luminous road fence 1 used in the self-luminous road fence apparatus, FIG. 2 shows a plan view thereof, and FIG. 3 shows a sectional view thereof. The self-luminous road fence 1 has a rectangular box-shaped main body case 10, and the main body case 10 is formed by opening an upper portion by casting of an aluminum alloy or the like, and a transparent synthetic resin or the like is formed on the opened upper portion. A plate 11 is applied and closed.

  On the other hand, a substrate (circuit board) 13 on which the light emitters 12 of the automobile light emitting unit 5 and the pedestrian light emitting unit 6 are mounted is mounted directly below the transparent plate 11 in the main body case 10. As shown in FIG. 2, the substrate 13 is formed to have a substantially square plane, and the mounting portions of the light emitters 12 are formed to protrude from the respective edges of the four sides of the substrate 13. The plurality of light emitters 12 are mounted at intervals so that light is emitted obliquely upward. The plurality of light emitters 12 mounted on the edge of each side of the substrate 13 constitute an automobile light emitting part 5 and a pedestrian light emitting part 6.

  For example, full-color LEDs are used for the light emitters 12 of the car light-emitting unit 5 and the pedestrian light-emitting unit 6, and the controller 20 uses different light emission colors, or detects a pedestrian or the like, a road surface frozen state, or the like. Depending on the situation, the emission color of the light emitter 12 of the car light emitter 5 and the light emitter 12 of the pedestrian light emitter 6 can be controlled to switch to, for example, blue light, red light, yellow light, green light, etc. It has become.

  As shown in FIG. 7, the light emitting section of the self-light-emitting road fence 1 includes a plurality of 12 light emitters 12 arranged at the edge on the side that emits light to the roadway side, and serves as an automobile light emitting section 5. As described above, the plurality of light emitters 12 arranged at the edge on the side of emitting light toward the pedestrian crossing 4 constitute the pedestrian light emitting section 6.

  On the other hand, as shown in FIG. 9, in the control mode in which the light emitting unit of the self-luminous road fence 1 emits light for pedestrians parallel to the pedestrian crossing 4, A plurality of light emitters 12 arranged on both side edges constitute the pedestrian light emitter 6.

  As shown in FIG. 3, the transparent plate 11 at the top of the self-luminous roadway 1 is fitted to the upper part of the main body case 10 so as to cover the light emitting bodies 12 of the light emitting part 5 for automobiles and the light emitting part 6 for pedestrians from above. Worn and fixed. On the lower surface of the transparent plate 11, an incident portion for entering light emitted from the light emitter 12 is formed as a substantially V-shaped groove, and the light of the light emitter 12 irradiated obliquely from below is efficiently used. The light enters the transparent plate 11 well. Furthermore, a light diffusing surface that diffuses and emits the introduced light is formed on a part or top surface of the bottom surface of the transparent plate 11, and the light of the light emitter 12 is efficiently emitted obliquely upward through the transparent plate 11. Structure.

  Further, as shown in FIG. 3, a solar cell (solar cell panel) 14 is disposed on the central portion of the substrate 13, receives sunlight incident through the transparent plate 11 in the daytime, and the solar cell 14 It is configured to generate electromotive force. Note that the solar cell 14 can be installed outside the case such as in the vicinity of the road, instead of inside the main body case 10 of the self-luminous road fence 1.

  A power storage device 15 is housed in the main body case 10 below the substrate 13. The power storage device 15 includes a power storage unit such as an electric double layer capacitor, and further, a constant voltage charging circuit for charging the power storage unit with an electromotive force generated by the solar cell 14 in the daytime, and light emission of the power storage unit at night A switching circuit that switches between a discharging circuit and a charging circuit of the power storage body between day and night is provided in the power storage device 15 so as to be supplied to the body 12. Further, in the main body case 10, based on a control signal from the controller 20, the emission colors of the light emitters 12 of the car light emitting unit 5 and the pedestrian light emitting unit 6 are blue light, red light, yellow light, and green light. A control circuit for switching to light blue light or the like is incorporated.

  As described above, the self-light-emitting road fence 1 includes the solar battery 14 that receives sunlight and generates an electromotive force, and the power storage device 15 that stores the electric power of the solar battery 14. The light emitter 12 can be blinked using the power of the power storage device 15.

  The self-luminous road fence 1 having the above configuration is installed at an appropriate interval along the pedestrian crossing 4 as shown in FIG. 4 at an intersection (one lane on one side) with an opposite lane, for example. Is done. That is, as shown in FIG. 4, the self-luminous road fence 1 is disposed in the vicinity of the end of each white belt of the pedestrian crossing 4 and the side of the automobile on the pedestrian crossing 4 (the side on which the automobile enters the pedestrian crossing). It is arranged along. Thus, for pedestrians on the pedestrian crossing 4, as shown in FIG. 8, the illuminant 12 of the pedestrian light emitting section 6 of the self-luminous roadway 1 that illuminates the side of the pedestrian crossing varies depending on the situation. The light can be irradiated. If the light emitter 12 of the light emitting unit 6 for pedestrians emits white light or yellow light, the white belt of the pedestrian crossing 4 can be illuminated brightly and the feet of pedestrians can be illuminated brightly.

  In addition, as shown in FIG. 9, the pedestrian light emitting section 6 of the self-luminous roadway 1 can be set to a control mode in which light is emitted in parallel with the length direction of the pedestrian crossing. The light emitter 12 of the light emitting unit 6 emits blue light or yellow light in parallel with the length direction of the pedestrian crossing 4 to clearly display the position of the pedestrian crossing and a crossable state to a pedestrian or the like. it can.

  On the other hand, as shown in FIG. 7, for a car traveling on the roadway side, the light emitting body 12 of the car light emitting unit 5 of the self-light-emitting road fence 1 that irradiates the car side entering the pedestrian crossing, The driver can be irradiated with light of a color according to the situation.

  A pedestrian detector 2 is installed in the vicinity of the pedestrian crossing 4 in order to detect pedestrians entering the pedestrian crossing 4 and pedestrians exiting from the pedestrian crossing 4 as shown in FIG. As shown in FIG. 10, the pedestrian detector 2 is configured by installing light transmissive beam sensors that project two parallel light beams at both ends of the pedestrian crossing 4. When a pedestrian or the like enters the pedestrian crossing 4 from the left, the pedestrian detector 2 detects the entry of the pedestrian or the like when the pedestrian or the like blocks the light beam B2 following the light beam B1. When the pedestrian or the like exits the pedestrian crossing 4, the pedestrian or the like blocks the light beam B3 following the light beam B4, so that the pedestrian detector 2 detects the exit of the pedestrian or the like.

  On the other hand, the pedestrian detector 2 detects the entrance of a pedestrian or the like by blocking the light beam B4 following the light beam B3 when the pedestrian or the like tries to cross from the right in FIG. After that, the pedestrian and the like block the light beam B1 following the light beam B2, thereby detecting the exit of the pedestrian and the like from the pedestrian crossing, and the detection signals of the entrance and exit of the pedestrian and the like, respectively. It is supposed to be sent to 20.

  In addition, although the said pedestrian detector 2 used the light transmission type sensor which detects a pedestrian etc. according to interruption | blocking of a light beam, it replaces with a light transmission type sensor, and reflects the light beam which hits the pedestrian etc. A light reflection type sensor that receives light and detects a pedestrian or the like can also be used.

  When the controller 20 as the control means inputs a detection signal indicating entry of a pedestrian or the like into a pedestrian crossing, for example, the pedestrian light-emitting unit 6 of each self-luminous roadway 1 is blinked or lit with blue light, On the other hand, the automobile light emitting section 5 of each self-luminous roadway 1 operates to blink with red light.

  Further, when the pedestrian detector 2 detects that a pedestrian or the like crossing the pedestrian crossing 4 enters the pedestrian crossing 4, the controller 20 controls lighting of the light emitter 12 of the pedestrian light emitting unit 6, and Control is performed so that light or yellow light is emitted parallel to the length direction of the pedestrian crossing 4. On the other hand, the automobile light emitting unit 5 is controlled to blink with red light. The lighting operation of the blue light or yellow light of the light emitting unit 6 for pedestrians and the blinking operation of the red light of the light emitting unit 5 for automobiles are performed until the pedestrian or the like enters after entering the pedestrian crossing 4, that is, walking. This is performed while the person crosses the pedestrian crossing 4 and after the pedestrian has crossed the pedestrian crossing 4, the pedestrian light emitting unit 6 is turned off and the vehicle light emitting unit 5 is turned off.

  In principle, the controller 20 detects that the pedestrian detector 2 detects the entry of the pedestrian or the like after the pedestrian detector 2 detects that the pedestrian or the like has entered the pedestrian crossing and outputs the detection signal. Until the detection signal is output, the lighting and flashing of the pedestrian light-emitting unit 6 and the flashing of the automotive light-emitting unit 5 are continued, but the position where the pedestrian and the like are out of the pedestrian detector 2 from the middle of the pedestrian crossing. Assuming the case of leaving the vehicle, the controller 20 is preset with a maximum lighting flashing time, and even after detecting the entry to the pedestrian crossing, such as a pedestrian, When the maximum lighting / flashing time elapses, the light emitting operations of the pedestrian light emitting unit 6 and the car light emitting unit 5 disappear.

  The controller 20 that performs such operation processing includes, for example, a single-chip CPU that executes the above-described operation processing based on control program data stored in advance. A pedestrian detector 2 is connected to the input / output circuit. The signal line 9 led out from the controller 20 can be easily connected in series to each self-luminous roadway 1 as shown in FIG. 4 as one signal line (an electric wire having a pair of conducting wire portions).

  Note that a commercial power source can be used as the power source of the controller 20, but as with the self-light-emitting road fence 1, a solar cell, a power storage unit that stores an electromotive force of the solar cell, a constant voltage charging circuit, a discharging circuit, A power supply unit including a charge / discharge switching circuit can also be provided. If the power supply unit provided with a solar cell or the like is used as the power supply of the controller 20, it can be operated even when the commercial power supply is interrupted, and the self-light-emitting road fence 1 can be used as a road signal device during a power failure.

  On the other hand, the temperature sensor 7 is installed on the road surface in the vicinity of the pedestrian crossing 4 in order to detect freezing of the road surface, and the temperature sensor 7 is connected to the controller 20 as shown in FIG. When the temperature sensor 7 detects the freezing temperature of the road surface and outputs the detection signal, the controller 20 displays the car light emitting unit 5 and the pedestrian light emitting unit 6 of the self-luminous roadway 1 with a chromatic color indicating freezing of the road surface. When the road surface is frozen by light (for example, light of a color different from the signal color, such as green light or light blue light), when the road surface freezes, the self-light-emitting road fence 1 blinks to freeze the road surface to the driver, pedestrian, etc. It is designed to notify with the color of

  The pedestrian crossing 4 described above is provided on a road having a single lane center line as shown in FIG. 4, but as shown in FIG. Even a lane road can be applied. In this case, the plurality of self-luminous road fences 1 are arranged in a straight line only along one side of the pedestrian crossing 4.

  Moreover, as shown in FIG. 11, the self-light-emitting road fence 1 can also be arrange | positioned at each pedestrian crossing 4 provided in the intersection of a roundabout (rotary intersection). At the roundabout intersection, there is no traffic light, but when a pedestrian or the like enters a pedestrian crossing, the car light emitting part 5 and the pedestrian light emitting part 6 of the self-light-emitting road fence 1 are lit and blinking. Thus, since the presence of a crossing pedestrian or the like can be notified, the driver of the car can easily recognize the pedestrian and travel more safely.

  In addition, as a power source for the self-light-emitting road fence 1 and the controller 20, when a solar cell and a power storage body that stores the electromotive force of the solar cell are used, a large solar cell is placed on the central island (rotary island) in the center of the roundabout. A power source unit such as a power storage unit that stores the electromotive force of the solar battery, a charge / discharge switching circuit, or the like can be installed.

  Next, the operation of the self-luminous roadway device having the above configuration will be described. For example, when a pedestrian or the like enters the pedestrian crossing 4 on the road in FIG. 4, the pedestrian detector 2 detects the entry of the pedestrian or the like, and the detection signal is output to the controller 20. 20 performs lighting / flashing control of the self-light-emitting road fence 1.

  When the pedestrian detector 2 detects that a pedestrian or the like has entered the pedestrian crossing, the controller 20 causes each light-emitting road fence 1 to place its pedestrian light-emitting unit 6 on the pedestrian crossing side as shown in FIG. Aim and blink with blue or yellow light. Thereby, even if the pedestrian is an elderly person or a person with low vision, for example, the pedestrian light-emitting unit 6 of the pedestrian light-emitting unit 6 can safely cross while safely watching the blinking blue light or yellow light. You can cross the sidewalk 4.

  On the other hand, the automobile light emitting section 5 of each self-light-emitting road fence 1 blinks with red light toward the roadway as shown in FIG. Accordingly, when the driver of the automobile traveling on the roadway approaches the pedestrian crossing 4, the light emitter 12 of the automobile light emitting unit 5 of the self-luminous roadway 1 arranged along the pedestrian crossing 4 blinks in red light. The state can be clearly seen, and the automobile can be surely stopped before the pedestrian crossing 4 to ensure the safety of pedestrians and the like.

  Since the pedestrian detector 2 detects the entry and exit of a pedestrian or the like from a pedestrian crossing and outputs the detection signal to the controller 20, the controller 20 detects the blue light or yellow light of the pedestrian light-emitting unit 6. The lighting / flashing operation and the flashing operation of the red light of the car light emitting unit 5 can be carried out until the pedestrians enter the pedestrian crossing 4 and exit, that is, while the pedestrians cross the pedestrian crossing 4, After a pedestrian or the like has finished crossing the pedestrian crossing 4, the pedestrian light emitting unit 6 is turned off and the red flashing of the automobile light emitting unit 5 disappears.

  As described above, when a pedestrian or the like enters the pedestrian crossing 4, the pedestrian detector 2 detects the pedestrian or the like and a detection signal is output to the controller 20, and the controller 20 lights / flashes the self-light-emitting road fence 1. The lighting and blinking continues until the pedestrian or the like finishes crossing the pedestrian crossing 4. As a result, when a pedestrian or the like enters the pedestrian crossing 4, the self-luminous road fence 1 is lit and blinking. The pedestrians can cross the pedestrian crossing 4 safely.

  Moreover, since the pedestrian detector 2 detects the entrance to the pedestrian crossing 4 and the exit from the pedestrian crossing 4 of the pedestrian crossing the pedestrian crossing 4, the controller 20 causes the pedestrian or the like to cross the pedestrian crossing 4. Only during this time, the self-luminous road fence 1 is allowed to emit light, and after the pedestrian or the like has finished crossing the pedestrian crossing 4, the light emission can be surely turned off.

  In addition, for the driver of the car, the car light emitting section 5 of each self-luminous road fence 1 blinks in red light toward the roadway side, so the driver clearly sees it and passes the car to the pedestrian crossing. 4 can be surely stopped before 4 to ensure the safety of pedestrians and the like.

  On the other hand, when the road surface of the pedestrian crossing 4 freezes during cold weather such as winter, the temperature sensor 7 detects the freezing temperature and outputs a detection signal. At this time, the controller 20 inputs the freezing detection signal output from the temperature sensor 7 and indicates the freezing of the road surface of the light emitting body 5 of the automobile light emitting unit 5 and the light emitting unit 12 of the pedestrian 6 of each self-luminous roadway 1. For example, blinking operation is performed with green light or light blue light.

  The flashing operation of the light emitter 12 at the time of detecting freezing can be performed in preference to the flashing operation at the time of detecting a pedestrian or the like, but can also be performed together with the lighting / flashing operation at the time of detecting a pedestrian or the like. . When the road surface is frozen, the light-emitting body 12 of the self-luminous road fence 1 is blinked with green light or light blue light so that when the road surface is frozen, the road surface is frozen to the driver or pedestrian of the car. It is possible to display clearly and to prevent traffic accidents due to slip.
