Usage mode of crosswalk safety beam generator

The usage mode of the crosswalk safety beam generator 10 having the above-described configuration will be described in more detail with reference to the drawings as follows.

Figure 5 is a perspective view showing the usage mode of the crosswalk safety beam generator according to the present invention according to the vehicle progress signal, and Figure 6 is a perspective view showing the usage mode of the crosswalk safety beam generator according to the present invention according to the pedestrian walking signal. am.

First, the crosswalk safety beam generator 10 according to the present invention is installed in consideration of the environment such as roads and crosswalks. In the present invention, it will be explained as an example that the system is installed around a crosswalk in order to deliver a warning according to the signal system to pedestrians walking on the crosswalk and vehicles entering the crosswalk. That is, four crosswalk safety beam generators 11 according to the present invention can be mainly installed at positions corresponding to the corners of the crosswalk. In addition, if there is no fence around the crosswalk, pedestrians may cross the roadway outside the crosswalk. To prevent this, an additional auxiliary crosswalk safety beam generator 12 may be installed along the direction of the road.

As shown, the main crosswalk safety beam generator 11 is equipped with a light irradiation unit 200 to emit light in three directions, and the auxiliary crosswalk safety beam generator 12 emits light in one direction. A light irradiation unit 200 may be provided to irradiate the light. Of course, depending on the usage, all crosswalk safety beam generators 11 and 12 are provided with a light irradiation unit 200 so that they can irradiate light in four directions, and the operation of the light irradiation unit 200 is controlled by the control unit. It is obvious that it is possible to selectively control whether or not.

Since the crosswalk safety beam generators 11 and 12 according to the present invention can be controlled to interwork with the traffic lights provided at the crosswalk, as shown in FIG. 5, when the traffic light at the crosswalk is displayed in red, By irradiating light from the light irradiation unit 200 along the direction of the road, pedestrians can visually see the light that prevents them from entering the roadway, thereby preventing them from entering the roadway.

At this time, not only is light emitted from the light irradiation unit 200, but the display unit 400 may visually display a vehicle shape shade to indicate the vehicle's progress or various signs to prevent pedestrians from entering the roadway. Additionally, a voice signal can be provided through the speaker to prevent entry into the roadway and to request waiting.

And, as shown in FIG. 5, when the light irradiation unit 200 is emitting light to prevent pedestrians from entering the roadway, the pedestrian enters the roadway or is excessively close to the roadway and blocks the light emitted from the light irradiation unit 200. If it interferes with reception by the light receiving unit 300 provided on the bollard 100 on the other side, it can be determined that the pedestrian is entering the roadway. In this case, a warning signal may be generated to pedestrians through the speaker and display unit 400.

At the same time, the light irradiation unit 200, which irradiates light in the direction of the roadway, may also emit a flashing signal or light of another color to generate a warning signal about the possibility that a pedestrian may enter the roadway.

Thereafter, as shown in FIG. 6, when the crosswalk traffic signal is changed to a pedestrian signal, the light irradiation unit 200, which irradiates along the road direction to prevent pedestrians from entering the roadway, stops emitting light and moves along the roadway. The light irradiation unit 200 radiates light across, that is, in a direction corresponding to the crossing direction of the pedestrian.

Depending on the usage, light is radiated in the direction corresponding to the crossing direction a few seconds before a yellow signal or walking signal is generated at a traffic light, and if light is not received by the bollard 100 on the other side, the vehicle is sent through a voice signal, etc. In order to prevent pedestrians from crossing the stop line of the crosswalk, various signals can be generated through the sound generator or display unit 400 to assist pedestrians in crossing more safely. At this time, the light emitted from the light irradiation unit 200 may emit light of a different color so that drivers can feel the difference from the stop sign, or the light emitted from the light irradiation unit 200 may be emitted to blink.

In this way, as the light emitting unit 200 continuously irradiates light along the pedestrian crossing direction while the walk signal continues, vehicles can be prevented from entering the crosswalk.

Afterwards, when the walking time of the crosswalk is completed and the traffic light changes to red, as shown in FIG. 5, the light irradiation unit 200 in the direction corresponding to the crosswalk ends irradiation of light and returns to the direction corresponding to the road direction. The light irradiation unit 200 resumes irradiation of light.

However, people who walk slowly, such as the elderly or the disabled, may not be able to complete the crossing even if the crosswalk signal changes. At this time, the sensor unit 500 and the photographing unit 600 measure whether pedestrians remain on the crosswalk when the signal changes, and the control unit determines whether pedestrians remain on the crosswalk based on the measured information.

In this way, when pedestrians remain at the crosswalk, the light irradiation unit 200 in the direction corresponding to the road resumes irradiation of light, and the light irradiation unit 200 corresponding to the crossing direction resumes irradiation of light, as shown in FIG. 5. Irradiation of light can be maintained without stopping. Depending on the usage, the light may flash or emit light of a different color to convey to the driver of the vehicle that there are pedestrians remaining on the crosswalk.

Afterwards, when the control unit determines that there are no pedestrians remaining on the crosswalk according to the information measured by the sensor unit 500 and the photographing unit 600, the control unit irradiates light from the light irradiation unit 200 in the crosswalk direction. Complete.

In addition, when installed at a crosswalk without a traffic light depending on the usage, the light irradiation unit 200 operates to prevent pedestrians from entering the roadway, as shown in FIG. 5, and pedestrians When a crossing request is input through a switch, the photographing unit 600 and the sensor unit 500 measure the surrounding traffic situation, and the control unit makes a decision based on this to allow pedestrians to safely cross the roadway as shown in FIG. 6. can do.

In addition, in the present invention, the crosswalk safety beam generators 11 and 12 according to the present invention are explained with a focus on crosswalks, but they are installed at intersections without crosswalks to prevent vehicles from violating signals or tailgating. It is clear that this can lead to safety among vehicles.

The crosswalk safety beam generators 11 and 12 according to the present invention are provided with a light receiver 300 that receives the light irradiated from the adjacent bollards 100 from the other bollard 100, so the control unit detects the light from the other side more than a reference time. If the light emitted from the bollard 100 is not received, it may be recognized that an abnormality has occurred in the light irradiation unit 200 of the other bollard 100 or that an obstacle has been left unattended for a long time and this can be conveyed to the manager. Through this, it is possible to quickly maintain the area where an abnormality occurred. During such maintenance, maintenance is performed through the openings and closings on one side that require maintenance through the openings and closings provided on each side of the bollard (100), and the other side can be operated normally, thereby continuing to prevent safety accidents for drivers or pedestrians. can do.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the above-described embodiments should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the claims described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and the equivalent concept should be construed as being included in the scope of the present invention.
