Description

[Technical Field]

[0001] The present invention relates to a crosswalk safety beam generating device, and more particularly to a crosswalk safety beam generating device that can ensure the safety of drivers driving their vehicles and pedestrians walking on crosswalks by emitting a visually recognizable light in a direction along or perpendicular to the roadway so as to correspond to a crosswalk or intersection signal, thereby assisting smooth vehicle movement. [Background technology]

[0002] Normally, crosswalks are intended to allow pedestrians to cross the road safely from passing vehicles, and drivers are required to stop when pedestrians cross the road to ensure their safety. However, there is a problem in that some drivers violate this rule or injure pedestrians due to momentary inattention.

[0003] For this reason, most crosswalks are equipped with traffic lights to control vehicle traffic, but some drivers may not be able to fully check the traffic lights' signals or may recognize the signals too late and fail to temporarily stop their vehicles at designated locations such as safety lines.

[0004] Furthermore, even if vehicles stop in accordance with the traffic light signal, there is a problem that when the signal changes to a running signal, vehicles may start moving without checking for elderly or infirm people who have not been able to cross the pedestrian crossing within the allotted time, which can lead to accidents.

[0005] [Patent Document 1] Korean Published Utility Model Patent No. 20-2022-0000314 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been created to solve the problems of the related art, and its object is to provide a crosswalk safety beam generator that can ensure the safety of drivers driving their vehicles and pedestrians walking on crosswalks by emitting a visually recognizable light that corresponds to the traffic lights of a crosswalk or intersection along the direction of the roadway or perpendicular to the roadway, thereby assisting smooth vehicle movement.

[0007] The objects of the present invention are not limited to the above-mentioned objects, and other objects not mentioned will be apparent to those skilled in the art from the following description. [Means for solving the problem]

[0008] To achieve the above-described object of the present invention, a crosswalk safety beam generating device includes a bollard arranged on one side of a road; a light emitting unit arranged on one side of the bollard to emit light in at least one direction; a display unit arranged on one exterior side of the bollard to visually indicate whether a vehicle or pedestrian is approaching, waiting, or walking; and a control unit arranged on one interior side of the bollard to control the light emitting unit.

[0009] In this case, the light emitting unit may be configured to be adjustable in at least one of an emitting angle, brightness, and emitting distance of light.

[0010] In addition, a plurality of the bollards may be provided, and the crosswalk safety beam generating device may further include a light receiving unit that receives light emitted from the light emitting unit of the bollard provided on the other side to confirm the presence or absence of a pedestrian or vehicle or to confirm whether the light emitting unit is operating normally.

[0011] Furthermore, the control unit may be connected by wire or wirelessly to a signal light arranged adjacent to the bollard to control the light emitting unit or the display unit.

[0012] Furthermore, the crosswalk safety beam generating device may further include a sensor unit on one side of the bollard that recognizes vehicles or pedestrians and reports the recognition to the control unit, and the control unit may control the light irradiation unit or the display unit based on a signal from the sensor unit.

[0013] Furthermore, the crosswalk safety beam generating device may further include a photographing unit on one side of the bollard that photographs vehicles, pedestrians or the surrounding environment, and the control unit may control the light emitting unit or the display unit based on a signal from the photographing unit.

[0014] Furthermore, the pedestrian crossing safety beam generating device may further include an audio generating unit disposed on one side of the bollard so as to be connected to a control unit and generating an audio signal corresponding to the signals of the light emitting unit and the display unit.

[0015] Furthermore, the lower part of a signal post may be used as the bollard. [Effects of the Invention]

[0016] The crosswalk safety beam generating device according to the present invention has the following effects.

[0017] First, when the traffic signal is on for vehicles, the bollards arranged along the roadway emit beams at each other, making it easy for pedestrians to visually recognize this along with the traffic lights and preventing them from entering the roadway, thereby preventing accidents.

[0018] Secondly, when the pedestrian crossing signal is on, a beam is projected across the roadway from bollards located on both sides of the roadway, making it easier for vehicle drivers to visually recognize the stop signal, preventing vehicles from entering the crosswalk and thus preventing accidents.

[0019] Thirdly, there is an advantage that the control unit installed inside the bollard can be linked to the signal light, and the light emitting unit installed in the bollard can be automatically activated in response to the signal from the signal light.

[0020] Fourth, if there are pedestrians remaining on the crosswalk when the pedestrian crossing signal is completed, the sensor unit or the camera unit will recognize this and emit light to prevent vehicles from entering the crosswalk, thereby enabling the elderly, the physically disabled and the like to cross the crosswalk safely.

[0021] Fifth, since the bollards are equipped with a light-receiving unit that receives light emitted from adjacent bollards, if a vehicle or pedestrian attempts to enter when entry is prohibited, no light will be received by the light-receiving unit, which has the effect of instilling a sense of caution in the driver or pedestrian by using a corresponding visual or auditory signal.

[0022] Sixth, if light is not received by the light receiving unit for a certain period of time or longer, it can be determined that there is a malfunction in the light emitting unit of the bollard or that an obstacle has been left in that position for a long period of time, and measures can be taken promptly to address this.

[0023] Seventh, the light emitting unit has the effect of being able to generate a wide variety of highly visually recognizable signals by adjusting the intensity, distance, angle, etc. of the light emitting unit.

[0024] The effects of the present invention are not limited to those described above, and other effects not mentioned will be clearly understood by those skilled in the art from the claims.

[0025] The following drawings attached to this specification illustrate preferred embodiments of the present invention and, together with the detailed description of the invention, serve to further understand the technical concepts of the present invention.

[0030] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] Configuration of the crosswalk safety beam generator FIG. 1 is a perspective view of a generating device for a pedestrian crossing safety beam according to the present invention, FIG. 2 is a side view of a generating device for a pedestrian crossing safety beam according to the present invention, FIG. 3 is a side view of a generating device for a pedestrian crossing safety beam according to the present invention from another direction, and FIG. 4 is a perspective view showing the emission and reception of light by a generating device for a pedestrian crossing safety beam according to the present invention.

[0032] The pedestrian crossing safety beam generating device 10 according to the present invention is a device that is installed on one side of a road, preferably on one side of an intersection or a crosswalk, and is linked to the signals at the intersection or crosswalk to enable drivers or pedestrians to more easily visually and audibly confirm such signals in order to prevent accidents caused by vehicles and pedestrians violating the signals. As shown in Figures 1 to 4, the pedestrian crossing safety beam generating device 10 may broadly include a bollard 100, a light emitting unit, a light receiving unit 300, a display unit 400, a control unit, a sensor unit 500, an imaging unit 600, and a sound generating unit.

[0033] The bollard 100 forms the exterior of the pedestrian crossing safety beam generator 10 of the present invention and provides a space inside and outside where a wide variety of devices constituting the present invention can be installed. Such a bollard 100 is preferably columnar, preferably hollow, and its cross section is preferably circular or polygonal. The height of the bollard 100 is preferably a height that allows easy recognition by pedestrians and drivers. In particular, since the light emitted from the light-emitting unit 200 installed on the bollard 100 is preferably installed at a position relatively higher than the vehicle hood, the bollard 100 is preferably manufactured taking these conditions into consideration. The bollard 100 preferably has a height of 1.5 m to 2 m. Furthermore, stainless steel is preferably used as the material. Furthermore, the bollard 100 may be provided with a partially openable / closable opening / closing unit so that the light-emitting unit 200 or display unit 400 on one side can remain operational while the light-emitting unit 200 and display unit 400 on the other side are maintained during maintenance.

[0034] Depending on the usage, the bollard 100 may not be provided as a separate component, but may be used as the bollard 100 on one side of the lower part of a signal light pole installed around the road, preferably on one side of a crosswalk.

[0035] Although only one bollard 100 may be installed on one side of a road, it is preferable to install multiple bollards 100 to limit the illumination length of the light emitted from the light emitting unit 200 and to ensure smooth visibility for drivers and pedestrians. Since the present invention is described and illustrated with an emphasis on installation at a pedestrian crossing, the disclosure focuses on four bollards 100 being installed to completely surround the pedestrian crossing. However, this is merely one embodiment, and there is no limit to the number of bollards 100 that can be installed. The installation locations and number of bollards 100 can be selectively determined taking into account a wide variety of surrounding conditions, such as traffic volume, number of pedestrians, and road shape.

[0036] The light emitting unit 200 is a device disposed on one side of the bollard 100 and emits visible light that is visually visible to drivers or pedestrians. While any light emitting device capable of emitting visually recognizable light may be used as the light emitting unit 200, it is preferable to use an emitting device that emits an LED beam, and more preferably to use an emitting device that is capable of adjusting the emitting angle, intensity, brightness, color, and emitting distance of the LED beam. A plurality of such light emitting units 200 are preferably disposed in the longitudinal direction of the bollard 100, i.e., in the vertical direction, and it is preferable that the light emitting units 200 are disposed in multiple directions so that a single bollard 100 can emit light in a variety of directions. In one embodiment, a single bollard 100 is preferably disposed so that light is emitted toward the road to warn vehicles not to enter the crosswalk, and light is emitted in the same direction as the road to prevent pedestrians from entering the roadway. Needless to say, the direction in which light is emitted from one bollard 100 may be configured to emit light not only in one direction or both directions, but also in more directions, and each direction may be provided with multiple light emitting units 200 in the upper and lower directions. The direction and number of such light emission may be selectively determined taking into account the installation environment, etc.

[0037] When multiple bollards 100 are installed, the light receiving unit 300 receives light emitted from adjacent bollards 100 to determine whether the light emitting unit 200 on the other side is operating normally and to determine whether there are obstacles, such as pedestrians or vehicles, between the bollards 100. Any device may be used for this light receiving unit 300 as long as it can smoothly receive light emitted from the bollard 100 on the other side and quickly transfer the light reception signal to the control unit. The number of light receiving units 300 corresponds to the number of light emitting units 200 to check not only the presence or absence of obstacles but also the presence or absence of normal operation. For smooth light reception, it is preferable to install the light receiving units 300 adjacent to the light emitting units 200 or in a position corresponding to the light emitting units 200, taking into account the illumination angle of the light emitting units 200. In this way, by arranging multiple bollards 100 so that they can absorb the light irradiated by each other, it is possible to prevent the light irradiated from the light emitting units 200 from being irradiated in any direction, causing inconvenience.

[0038] In the present invention, the illustrations and explanations have focused on the light receiving unit 300 being arranged on the side of the light emitting unit 200, but depending on the mode of use, the light emitting unit 200 and the light receiving unit 300 may be arranged so that they are alternately arranged in the vertical direction. In such a case, the light emitting unit 200 may be arranged so that the light emitting angle is adjusted so that the light is received by the light receiving unit arranged on the bollard 100 on the other side. In other modes of use, the light emitting unit 200 and the light receiving unit 300 may be arranged in a variety of ways, such as arranging the light emitting unit 200 at the top end of one bollard 100 and arranging the light receiving units 300 in sequence, and arranging the light receiving unit 300 at the top end of the other bollard 100 and arranging the light emitting units 200 in sequence.

[0039] The display unit 400 is a device disposed on one side of the bollard 100 and capable of conveying various visual signals to pedestrians or drivers by providing other visual displays in addition to the light emitted from the light-emitting unit 200. In one embodiment, the display unit 400 may be at least one shadow display device disposed on one side of the upper portion of the bollard 100. More specifically, a shadow display device in the shape of a pedestrian is disposed on one side of the upper portion of the bollard 100 corresponding to the field of view of the vehicle driver and can be activated based on a signal from the control unit, and a shadow display device in the shape of a vehicle is disposed on one side of the upper portion of the bollard 100 corresponding to the field of view of the pedestrian and can be activated based on a signal from the control unit. In another embodiment, the display unit 400 may be a display device that displays a variety of phrases, symbols, numbers, etc. The display unit 400 may be any device that, together with the light-emitting unit 200, can visually and clearly convey an enter or stop signal to the driver or pedestrian.

[0040] The control unit is disposed on one side of the interior of the bollard 100 and controls the light emitting unit 200 and the display unit 400 based on information received from the outside. This control unit is configured to be able to link with external information, such as a traffic light, and can receive signal processing information from the traffic light and control the light emitting unit 200 and the display unit 400 accordingly. That is, when a vehicle traffic signal is turned on, the light emitting unit 200 and the display unit 400 are displayed facing the road to prevent pedestrians from entering the crosswalk. When a pedestrian crossing signal is turned on, the light emitting unit and the display unit 400 are operated facing the road to prevent vehicles from entering. In addition to being operated in conjunction with the traffic light, this control unit is also configured to be connected to the sensor unit 500 and the photographing unit 600, which can be further installed to take into account more diverse and complex situations, and can operate based on information linked to the sensor unit 500 and the photographing unit 600. It goes without saying that, depending on the usage, it is also possible to operate the control unit by wired connection with an administrator. For this purpose, the device may be provided with a communication unit that is connected to the administrator's terminal, control center, management server, etc. by wire or wireless.

[0041] Depending on the mode of use, the control unit may further include a sensor unit 500 and an image capturing unit 600 so that the control unit can more stably control the light irradiation unit 200 and the display unit 400. The sensor unit 500 and the image capturing unit 600 may be any device as long as they can smoothly confirm whether a vehicle is entering an intersection or a crosswalk, whether a pedestrian is entering a crosswalk or crossing, and transmit the information to the control unit.

[0042] In one embodiment, the sensor unit 500 may be a sensor capable of measuring the distance and speed of a vehicle approaching the side where the bollard 100 is installed, a sensor capable of measuring the approach of a pedestrian, or a variety of other sensors capable of detecting motion, speed, movement, etc.

[0043] In addition, the photographing unit 600 can use a camera or the like to photograph the surrounding conditions of the bollard 100, such as whether there are vehicles or pedestrians approaching the bollard 100, and whether there are vehicles or pedestrians not complying with the signal system of the traffic light, and transmit the obtained image or video information to the control unit so that it can be used as control information for the control unit.

[0044] The sound generating unit is a device such as a speaker that generates a buzzer or various audio signals to drivers or pedestrians who are unable to see the light emitting unit 200 and the display unit 400, which are provided on one side of the bollard 100 and connected to the control unit, and provide visual information. Such a sound generating unit may be any device that can operate simultaneously with the light emitting unit or the display unit 400 under the control of the control unit, or operate separately depending on the usage mode, and generate a variety of audio signals to prevent accidents from occurring.

[0045] Depending on the usage, an auxiliary battery unit may be further provided inside the bollard 100. Such an auxiliary battery unit can keep the pedestrian crossing safety beam generating device 10 according to the present invention operational for a certain period of time even if the external power supply is cut off due to various factors.

[0046] In addition, when the bollard 100 is installed in a place where there is no signal light, a switch may be further provided on one side of the bollard 100 to control whether or not the pedestrian crossing safety beam generating device 10 according to the present invention is activated so that pedestrians can cross the road safely.

[0047] Usage of the crosswalk safety beam generator The use of the crosswalk safety beam generating device 10 having the above-described configuration will be described in more detail below with reference to the accompanying drawings.

[0048] FIG. 5 is a perspective view showing a usage mode of the crosswalk safety beam generating device of the present invention based on a vehicle advance signal, and FIG. 6 is a perspective view showing a usage mode of the crosswalk safety beam generating device of the present invention based on a pedestrian walking signal.

[0049] First, the pedestrian crossing safety beam generator 10 of the present invention is installed taking into consideration the environment, such as the road and crosswalk. In one embodiment of the present invention, the pedestrian crossing safety beam generator 10 is installed around the crosswalk to alert pedestrians walking on the crosswalk and vehicles entering the crosswalk based on the signal system. That is, four pedestrian crossing safety beam generators 11 of the present invention can be mainly installed at positions corresponding to the corners of the crosswalk. Furthermore, if there is no fence around the crosswalk, there is a risk that pedestrians will cross the roadway outside the crosswalk. To prevent this, additional auxiliary pedestrian crossing safety beam generators 12 can be installed along the direction of the road.

[0050] As shown in the figure, the generator 11 for the main pedestrian crossing safety beam may be provided with a light emitting unit 200 so as to emit light in three directions, and the generator 12 for the auxiliary pedestrian crossing safety beam may be provided with a light emitting unit 200 so as to emit light in a single direction. Needless to say, it is obvious to those skilled in the art that, depending on the mode of use, all of the generators 11 and 12 for the pedestrian crossing safety beam may be provided with light emitting units 200 so as to emit light in four directions, and the operation of the light emitting units 200 may be selectively controlled by controlling the control unit.

[0051] The crosswalk safety beam generating devices 11, 12 according to the present invention can be controlled to be linked to the traffic lights installed at the crosswalk. Therefore, as shown in FIG. 5, when the traffic lights at the crosswalk are displayed in red, the light emitting unit 200 emits light along the direction of the road, allowing pedestrians to visually confirm the light that prevents them from entering the roadway, thereby preventing them from entering the roadway.

[0052] At this time, not only is light emitted from the light emitting unit 200, but the display unit 400 can visually display a shadow of the shape of a vehicle to indicate the progress of the vehicle or various marks to prevent pedestrians from entering the roadway. Also, a sound signal to prevent entry into the roadway and request waiting can be provided using a speaker.

[0053] 5, when the light emitting unit 200 is emitting light to prevent pedestrians from entering the roadway, if a pedestrian enters the roadway or gets too close to the roadway and blocks the light emitted from the light emitting unit 200, preventing the light from being received by the light receiving unit 300 installed in the bollard 100 on the other side, it can be determined that a pedestrian has entered the roadway. In such a case, a warning signal can be issued to the pedestrian using the speaker and display unit 400.

[0054] At the same time, the light emitting unit 200 that emits light in the direction of the roadway can emit a flashing signal or light of other colors to issue a warning signal against the possibility that a pedestrian may enter the roadway.

[0055] After that, as shown in FIG. 6, when the crosswalk signal light changes to a pedestrian signal, the light emitting unit 200 that emits light along the direction of the road to prevent the pedestrian from entering the roadway stops emitting light, and the pedestrian crosses the roadway, that is, the light emitting unit 200 in the direction corresponding to the pedestrian's crossing direction emits light.

[0056] Depending on the usage mode, the signal lamp may emit light in the direction corresponding to the crossing direction a few seconds before a yellow signal or a walking signal is generated, and if the light is not received by the bollard 100 on the other side, various signals may be generated using the sound generating unit or display unit 400 to prevent vehicles from crossing the stop line of the crosswalk using audio signals, thereby helping pedestrians to cross more safely. In this case, the light emitted from the light emitting unit 200 may be of a different color or may be flashing so that drivers can distinguish it from the stop signal.

[0057] In this way, the light emitting unit 200 continues to emit light in the crossing direction of the pedestrian while the pedestrian signal continues, thereby preventing vehicles from entering the crosswalk.

[0058] After that, when the crosswalk walking time ends and the traffic light turns red, as shown in FIG. 5 again, the light emitting unit 200 in the direction corresponding to the crossing direction stops emitting light, and the light emitting unit 200 in the direction corresponding to the road direction resumes emitting light.

[0059] However, in the case of people who walk slowly, such as the elderly, the physically disabled, and others, there is a possibility that they may not be able to cross the crosswalk even when the crosswalk signal changes. In this case, the sensor unit 500 and the photographing unit 600 measure whether or not pedestrians remain at the crosswalk when the signal changes, and the control unit determines whether or not pedestrians remain based on the measured information.

[0060] In this way, when a pedestrian remains at the crosswalk, the light emitting unit 200 in the direction corresponding to the road basically resumes emitting light, and the light emitting unit 200 in the crossing direction can continue emitting light without terminating light emission, as shown in Fig. 5. Depending on the mode of use, the light emission can be flashed or light of a different color can be emitted to notify the driver of the vehicle that a pedestrian remains at the crosswalk.

[0061] After this, if the control unit determines that there are no pedestrians remaining on the crosswalk based on the information measured by the sensor unit 500 and the photographing unit 600, the control unit stops emitting light from the light emitting unit 200 in the crossing direction.

[0062] Furthermore, depending on the usage, when the device is installed at a crosswalk without traffic lights, the light emitting unit 200 and the like are basically activated to prevent pedestrians from entering the roadway, as shown in FIG. 5, and when a pedestrian uses a switch to input a request to cross, the photographing unit 600 and sensor unit 500 measure the surrounding traffic conditions, and the control unit makes a decision based on this, allowing the pedestrian to cross the roadway safely, as shown in FIG. 6.

[0063] Furthermore, in the present invention, emphasis has been placed on crosswalks and the description has been given with an emphasis on the crosswalk safety beam generating devices 11, 12 according to the present invention, but it is obvious to those skilled in the art that the crosswalk safety beam generating devices can be installed at intersections without crosswalks to prevent vehicles from violating traffic signals or no-entry signs at intersections, etc., thereby guiding vehicles to safety.

[0064] The pedestrian crossing safety beam generators 11, 12 according to the present invention are provided with a light-receiving unit 300 that receives light emitted from an adjacent bollard 100 at the other bollard 100. If the control unit does not receive light emitted from the other bollard 100 for a reference time or longer, it recognizes that an abnormality has occurred in the light-emitting unit 200 of the other bollard 100 or that an obstacle has been left unattended for a long period of time, and notifies the administrator of this fact. This allows for prompt maintenance of the abnormality. During such maintenance, the opening / closing units provided on each side of the bollard 100 are used to perform maintenance on the one side that requires maintenance, while the remaining part on the other side remains operational, allowing for continued prevention of accidents involving drivers or pedestrians.

[0065] As described above, those skilled in the art to which the present invention pertains should understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments should be understood to be merely illustrative in all respects and not limiting. The scope of the present invention is defined by the claims set forth below, rather than the detailed description, and all modifications and variations derived from the meaning and scope of the claims and their equivalents should be construed as being within the scope of the present invention.
