The illuminating lamp includes a first light-emitting lamp that provides different lighting to the driver according to the movement of the pedestrian near the pedestrian crossing, and a second light-emitting device that illuminates the pedestrian crossing so that the pedestrian can be identified according to whether or not the pedestrian can cross. .

  The alarm device may include a variable control unit that variably controls the blinking time, color, or brightness of the first light-emitting lamp and the second light-emitting lamp as the vehicle approaches the pedestrian crossing.

  When there is no pedestrian approaching the pedestrian crossing, the first luminous lamp is lit at the first level of brightness and the first color, and when the pedestrian approaches the pedestrian crossing, it is lit at the second level. When the person crosses the pedestrian crossing without permission, the second color may be flashed.

  When the pedestrian crosses the pedestrian crossing, the second light-emitting lamp illuminates the area within the outer line of the pedestrian crossing, and when there is no pedestrian crossing the pedestrian crossing, the area within the outer line of the pedestrian crossing is simply displayed. It can also be configured to illuminate.

  The pedestrian sensing unit may include a plurality of sensors so as to distinguish and control whether or not a pedestrian can approach the pedestrian crossing and whether or not the pedestrian crosses.

  Hereinafter, the pedestrian protection apparatus according to the present invention will be described in detail according to the embodiments illustrated in the accompanying drawings, and detailed descriptions of related known functions and components will be omitted.

  FIG. 1 is an installation diagram showing an example in which a pedestrian protection lighting device related to the present invention is installed at an intersection.

  As shown in FIG. 1, a large number of pedestrian crossings 2 are generally installed at an intersection 1. An alarm 10 is installed at the entrance of each pedestrian crossing 2 to detect pedestrians and call attention to pedestrians and vehicles.

  The alarm device 10 can be installed at two left and right positions corresponding to positions on the sidewalk most on both sides of the pedestrian crossing 2. In this case, whether or not the pedestrian can enter the pedestrian crossing 2 can be more accurately sensed, and an alarm signal can be transmitted from the opposite side to the approaching vehicle 3.

  A vehicle sensing unit 20 that senses whether or not the vehicle is approaching can be installed in front of the alarm device 10 by a certain distance from the traveling direction of the vehicle 3.

  The vehicle sensing unit 20 can include various sensor devices, which use an optical sensor type that detects whether light such as infrared rays is blocked by a passing vehicle, or uses sound waves or ultrasonic waves. A sensing type is possible. In particular, when an ultrasonic sensor is used, there is a merit that there is little problem of performance degradation due to dust and the like, and reliability is excellent. In the case of using an ultrasonic sensor, the control signal can be made different for each movement of the vehicle, such as a stopped vehicle, a parked vehicle, or a vehicle approaching a pedestrian crossing due to a speed violation. Control is possible. In a place where the width of the roadway is wide and the vehicle sensor is difficult to be installed, the approach of the vehicle can be detected more accurately by using a loop detector.

  The installation position of the vehicle sensing unit 20 may be on a pillar such as a street lamp along the road or various road accessories. It is also possible to embed in the ground and expose only the sensing part to the ground.

  The distance of the vehicle detection unit 20 to the pedestrian crossing is preferably arranged sufficiently far from the minimum distance that the driver can be alerted by the warning signal of the alarm 10, and the average speed of the vehicle traveling on the road, the pedestrian crossing It can be decided in consideration of the situation such as whether the road is curved in front of 2.

  Signal transmission of the vehicle sensing unit 20 to the alarm device 10 is performed by a wired or wireless method. That is, when wired, the cable can be buried in the ground or installed along a power pole, and when wireless, the alarm device 10 of the vehicle sensing unit 20 includes an antenna device for wireless transmission.

  FIG. 2 is an installation diagram showing an example in which a pedestrian protection lighting device related to the present invention is installed in the vicinity of a pedestrian crossing.

  Referring to FIG. 2, the vehicle sensing unit 20 is provided for each direction of vehicle travel. Each vehicle sensing unit 20 transmits a control signal to the alarm device when the vehicle passes a certain distance from the pedestrian crossing 2.

  When a control signal is transmitted from the vehicle sensing unit 20 to the alarm device 10, the alarm device 10 knows whether there is a pedestrian crossing in that situation, and if there is a pedestrian crossing, it drives a caution signal To provide

  The caution signal can be set so as to be generated from all alarm devices 10 placed around the entrance of the pedestrian crossing 2 or only to some alarm devices 10.

  3 is a front view of an alarm device related to the present invention, and FIG. 4 is an operational state diagram of the alarm device of FIG.

  As shown in FIG. 3, each alarm device 10 includes a support column 11 installed so as to be able to stand from the ground. The lower part of the support | pillar 11 is supported by the base 12 fixed to the ground. The alarm device 10 can use a material that absorbs an impact and is folded inward. Such an alarm device 10 has an advantage in place of a vehicle entry prevention structure (for example, a bollard ballard) that can be additionally installed in a human road by being set at a position that can prevent the vehicle from entering.

  The alarm device 10 is configured to be separately replaceable for each part, and it is desirable that the corresponding part or part can be easily replaced when damage occurs.

  The column 11 is provided with an illuminating lamp 30 that calls attention to the driver or pedestrian, that is, illuminates the pedestrian. A plurality of illumination lamps 30 can be installed depending on the function.

  As an example, a first light-emitting lamp 31 configured to be able to provide different lighting to the driver according to the movement of a pedestrian near the pedestrian crossing 2 is installed at the upper part of the support post 11, and the walk at the lower part of the support post 11 The 2nd light emission lamp 32 comprised so that the illumination which can identify a pedestrian by the possibility of a person's crossing is provided is installed.

  The first light-emitting lamp 31 is configured to operate as follows.

  First, when there is no pedestrian approaching the pedestrian crossing 2, the first light-emitting lamp 31 is lit in the first color (for example, white) at the brightness of one level (for example, the maximum brightness of 30%). Can be maintained.

  If the pedestrian approaches the pedestrian crossing 2, the output can be increased so that the first light-emitting lamp 31 is lit at the second stage level (for example, maximum brightness 100%). By increasing the brightness level in this way, it is possible to preliminarily strengthen attention to the driver who passes the pedestrian crossing 2.

  When the pedestrian crosses the pedestrian crossing 2 without permission, that is, when the pedestrian crosses the pedestrian crossing 20 in spite of the pedestrian signal being red, the first light-emitting lamp 31 second color (for example, By flashing (red), the driver is informed of a dangerous situation. In this case, a speaker can be installed in the alarm device 10 so as to provide an audio alarm signal, so that the pedestrian can be further noticed.

  The second light-emitting lamp 32 is configured to operate as follows.

  When a pedestrian crosses the pedestrian crossing 2, the second light-emitting lamp 32 guides the pedestrian to correctly cross within the range of the pedestrian crossing 2 so as to illuminate a range inside the outline of the pedestrian crossing 2. At this time, the second light-emitting lamp 32 can be flashed at a constant time interval to increase the attention of the pedestrian and the driver. The emission color of the second light-emitting lamp 32 can also be embodied in a plurality of forms.

  If there is no pedestrian crossing the pedestrian crossing 2 even though the pedestrian traffic light is green, the second light-emitting lamp 32 illuminates the pedestrian crossing 2 and calls the driver for preliminary attention. You can guide where to pass.

  Furthermore, such a second light-emitting lamp 32 is effective in allowing the driver to easily identify whether or not a pedestrian can cross when the periphery of the pedestrian crossing 2 is dark.

  A pedestrian sensing unit 40 for sensing a pedestrian is installed on the support 11. Various types of sensors constituting the pedestrian sensing unit 40 can be applied, and an optical sensor or an ultrasonic sensor using infrared rays or the like is used. As an example, it is possible to identify whether a pedestrian is crossing a pedestrian crossing by placing an infrared light emitting unit and a light receiving unit at the entrance of a pedestrian crossing, that is, both alarms standing at the boundary between the sidewalk and the roadway. In addition, the sensor which senses a speed | rate can be provided so that a pedestrian's approach speed can be distinguished and controlled. In particular, such a sensor is composed of a plurality of sensors, and has an advantage that one or more of the sensors can operate normally when one or more fail.

  In addition, the pedestrian sensing unit 40 includes a camera, so that sensing by photographing is also possible.

  FIG. 5 is an operational state diagram for detecting the approach of a pedestrian around the alarm device. Each alarm device is provided with a pedestrian sensing unit 40 for sensing a pedestrian, and these are combined with each other to determine whether or not the pedestrian can approach the pedestrian crossing 2, that is, whether or not they are approaching. And whether or not the pedestrian crossing 2 can be crossed, that is, whether or not the pedestrian crossing 2 is crossed.

  FIG. 6 is a perspective view illustrating an operating state of the first light emitting unit and the second light emitting unit. As shown in FIG. 6, the alarms are respectively disposed at the entrances of the pedestrian crossing, and provide a warning signal to the vehicle passing through the pedestrian crossing by the first light emitting unit 31 and the second light emitting unit 32. .

  FIG. 7 is a block diagram of a pedestrian protection lighting device related to the present invention. As disclosed in FIG. 7, the pedestrian protection device receives signals from the pedestrian sensing unit 40 and the vehicle sensing unit 2 and controls the lighting signals of the first light-emitting lamp 31 and the second light-emitting lamp 32. It comprises.

  The control unit 50 is approved for the control signal of the vehicle sensing unit 20, that is, whether or not the vehicle is accessible or the vehicle speed. When there is a vehicle approach signal from the vehicle sensing unit 20, the pedestrian sensing unit 40 transmits whether or not the pedestrian is approaching the pedestrian crossing 2 or crossing the pedestrian crossing 2 next. However, the reception of the control signal of the vehicle sensing unit 20 and the reception of the control signal of the pedestrian sensing unit 40 can be performed in the reverse order.

  Accordingly, when there is a vehicle approach signal from the vehicle sensing unit 20 and a pedestrian approaches or crosses a pedestrian crossing, the first light emitting unit 31 is turned on to call the driver approaching. .

  Furthermore, the control unit 50 can variably adjust the blinking time or brightness of the first light-emitting lamp 31 as the vehicle approaches the pedestrian crossing. For example, as the vehicle 3 approaches the pedestrian crossing, it is possible to shorten the blinking cycle or gradually increase the brightness. Therefore, the driver's attention approaching the pedestrian crossing can be concentrated.

  The alarm device 10 further includes a wireless alarm signal providing unit 52 that wirelessly provides an alarm signal to a vehicle approaching a pedestrian crossing, thereby alerting the driver through a speaker mounted on the vehicle. The wireless alarm signal providing unit 52 may include an antenna device for short-range wireless communication. In this case, the wireless alarm signal providing unit 52 can be configured to operate together with the first light emitting unit 31 or independently of the first light emitting unit 31 according to the control signal of the control unit 50.

  The second light emitting unit 32 can be controlled by the illuminance sensor 51 according to the day and night surrounding conditions so that the pedestrian crossing 3 becomes dark and helps the pedestrian to cross the pedestrian so that the driver can easily identify the pedestrian.

  The brightness of the second light emitting unit 32 can be adjusted separately when the pedestrian crossing 3 has a pedestrian and when there is no pedestrian. For example, when there are no pedestrians on the pedestrian crossing 3, it can be operated at a brightness of 20 to 40% to save power, and when there are pedestrians on the pedestrian crossing 3, it can operate at a brightness of 80 to 100%. .

  According to the pedestrian protection device in the present invention as described above, as an example, whether or not a vehicle to turn right is crossing a pedestrian at a pedestrian crossing before entering the pedestrian crossing. Can help prevent accidents.

  Moreover, according to the pedestrian protection device of the present invention, as another embodiment, it can be used as a substitute signal such as a pedestrian signal at a pedestrian crossing where no signal is installed.

  Furthermore, as another example, driving in a careless crossing of a pedestrian before and after a special safety zone such as a school zone or a vehicle parked around a road (especially a large vehicle such as a truck or a bus). The accident can be prevented by informing the person of the situation of crossing with a warning such as a light.

  As described above, the present invention provides a warning device installed at the entrance of a pedestrian crossing on a road, a pedestrian sensing unit that senses the movement of a pedestrian, and a driver or pedestrian that is installed in the warning device and calls attention. A pedestrian protection device is provided that includes an illumination light. The illuminating lamp includes a first light-emitting lamp that provides different lighting to the driver according to the movement of the pedestrian near the pedestrian crossing, and a second light-emitting device that illuminates the pedestrian crossing so that the pedestrian can be identified according to whether or not the pedestrian can cross. . Thereby, in each situation where a pedestrian crosses, attention can be drawn toward the vehicle approaching the pedestrian crossing to prevent an accident, and it can function as a comprehensive road safety device.

  As an example of an application example of the present invention, the alarm device includes a variable control unit that variably controls the blinking time, color, or brightness of the first light-emitting lamp and the second light-emitting lamp as the vehicle approaches the pedestrian crossing. Therefore, it is desirable to increase the driver's attention.

  As an example of an application of the present invention, the first luminous lamp is lit with the first level of brightness and the first color when there is no pedestrian approaching the pedestrian crossing, and the second light is emitted when the pedestrian approaches the pedestrian crossing. It can be configured to light up at a step level and to flash the second color when the pedestrian crosses the pedestrian crossing without permission.

  As an example of application of the present invention, the second light-emitting lamp illuminates a blinking area within the outline of the pedestrian crossing when the pedestrian crosses the pedestrian crossing, and when there is no pedestrian crossing the pedestrian crossing, the outline of the pedestrian crossing It can be configured to simply illuminate the area within the line.

  As an example of an application example of the present invention, the pedestrian sensing unit may include a plurality of sensors so as to be able to distinguish and control whether or not a pedestrian approaches the pedestrian crossing and whether or not the pedestrian crosses.
