Description

Information notification system of jaywalking pedestrians

The present invention relates to a system for providing information on pedestrians trespassing, and more particularly, when there is a pedestrian crossing the road at night, a warning light installed on the road center line is emitted to make the driver aware that there is a pedestrian crossing the road, so that defensive driving is possible. It is related to a system for providing information on pedestrians trespassing that can prevent vehicle accidents with pedestrians trespassing.

In general, today's society is undergoing rapid development of road transportation, and as automobiles are used as a popular means of transportation, traffic accidents cause hundreds of thousands of casualties and property damage every year. Traffic accidents are also significantly changing traffic patterns as human and material exchanges between regions increase due to frequent movement due to urban concentration of population and increase in economically active population, and a rapid increase in leisure population due to working five days a week.

The advent of automobiles, which are indispensable in modern life, is beneficial to us, but since automobiles occupy a significant portion of the road that both drivers and pedestrians should share, pedestrians' right to walk, which is a basic human right, is restricted. leading to disastrous results.

According to statistics, the total number of traffic accidents in the first half of this year was about 100,000, down 0.9% from the same period last year. As a result, pedestrian traffic accidents increased by 1.1% from 24,183 to 24,453. Pedestrian traffic fatalities accounted for 940 people, or 37.4% of all deaths, and 24.1% (227 people) of them were found to have been involved in an accident while jaywalking. Among them, it was found that the highest number of pedestrian crossing accidents occurred during the night time (18:00 to 24:00).

Most of pedestrian traffic accidents occur while crossing a crosswalk or road, so the coexistence of vehicles and pedestrians in a specific road section is very serious. If we look at the types of pedestrian traffic accidents in detail, they often occur due to driver's negligence, careless driving, and driver's self-centered driving behavior. Accidents occur due to the production of walking culture, etc.

Especially at night, most of the traffic lights are switched to flashing lights on arterial roads except for major roads. In addition, even if the driver pays attention to forward gaze, the night vision is shorter than during the daytime, so it takes a considerable amount of time for the driver to recognize the pedestrian, so accidents between the vehicle and the pedestrian occur frequently.

Accordingly, some methods have been proposed to induce defensive driving by illuminating a lamp to provide information on whether or not a pedestrian is present to the driver.

Korean Patent No. 10-1130225 (registration on March 19, 2012; hereinafter referred to as 'Prior Document 1') suggests a trespassing warning system for drivers on national roads. The prior document 1 installs a panel that emits light at the edge of the road, and installs a pressure sensor on the panel to detect when a pedestrian steps on and applies a load, and also installs a motion sensor to detect whether a pedestrian is crossing, and in the control unit Judgment is made to emit light.

However, since the prior document 1 is installed on the bottom surface of the road edge, a large amount of light generated is irradiated to the upper side, and direct light irradiation is weak to a driver approaching from the side. There is a disadvantage in that the installation cost increases as a large amount is installed in the form of a belt.

Korean Patent Registration No. 10-1475453 (registered on December 16, 2014; hereinafter referred to as 'Prior Document 2') suggests a trespassing detection system. The prior document 2 installs cameras on streetlights installed on both sides of the road to capture the road situation as an image, analyze it, detect trespassing, and provide information to vehicles approaching the trespassing point so that deceleration or recognition is achieved. there is.

In the preceding document 2, various information is provided by wireless communication between road facilities and vehicles, but the cost is excessively consumed to build the system even on a local road, and thus the reality is low.

Therefore, there is a need for a device that can be installed in a necessary place while minimizing the installation cost to induce a defensive driving by allowing the driver to recognize that there is a pedestrian crossing the road.

1 is a plan view showing a road to which the jaywalking information providing system according to the present invention is applied, and FIG. 2 is a configuration diagram of the jaywalking pedestrian information providing system according to the present invention.

As described above, the system 10 for providing information on pedestrians trespassing according to the present invention includes a detection sensor device 20 installed on a sidewalk adjacent to a road boundary stone, and a light emitting display device 60 installed at the center line of the road width to emit light. ) is included.

The detection sensor device 20 and the light emitting display device 60 may be installed over the entire road, but preferably a school zone area, a crosswalk area where traffic lights change to flashing lights at night, and nighttime trespassing. Can be installed in places where traffic accidents are frequent

The detection sensor device 20 is separated into a light emission sensor 30 for irradiating laser light for detection accuracy, and a light reception sensor 40 for detecting a change in the irradiated light. The distance between the light emitting sensor 30 and the light receiving sensor 40 may be varied according to the intensity of the irradiated light, and in order to accurately detect the detection signal, it may be used by disposing the detection in two lines. Therefore, even if one side has a problem in operation, the other side can detect normal and transmit a detection signal. In the drawing, two light emitting sensors 30 and two light receiving sensors 40 are placed on one side of the road on both sides of the starting point of the crosswalk to make double detection. It can be arranged in various forms, such as by arranging the light-receiving sensor to form a narrow gap between the light-emitting sensor and the light-receiving sensor.

In addition, the detection sensor device 20 is formed in a cylindrical shape and installed on the sidewalk close to the road boundary, and preferably, it can be installed at a certain height or higher by applying to a blocking post for preventing vehicle entry frequently used in crosswalks.

The light emitting display device 60 is installed at the center of the road, for example, at a midpoint of the center line or the width of the road. In Fig. 1, when applied to a crosswalk, it is installed at the center and on both sides of the crosswalk among the midpoints of the road width, and emits light at a plurality of points at the same time so that the approaching driver can easily recognize the situation.

In addition, when installing on a general road rather than a crosswalk area, the light emitting display device 60 may be installed on the center line line to irradiate light to vehicles approaching from both sides of the road to provide information on whether or not pedestrians are present.

The light emitting sensor 30 according to an embodiment of the present invention includes a light emitting unit 31 for irradiating light, a light emitting sensor power supply unit 32 for supplying power to the light emitting unit, and a light emitting sensor for controlling a signal in the sensor It is configured to include a control unit 34 and a light emitting sensor case 35 having a light irradiation hole through which the light of the light emitting unit is irradiated.

As described above, the light emitting sensor case 35 may be provided in various forms, and the light irradiation hole is closed with a material that transmits light, such as glass, transparent plastic, etc. It is preferable to provide a structure.

The light emitting unit 31 installed inside the light emitting sensor case may typically be a laser or infrared light, and a known radio wave or sound wave for detecting an object may be used instead. For example, when radio waves are applied, a pair of guide plates are installed so that the irradiated radio waves intensively travel in a desired direction, so that the propagation of the radio waves can be made in the width of the inner space of the pair of guide plates.

The light emitting sensor power supply unit 32 may be connected to a constant power source or supply power through a separate primary or secondary battery. Here, the secondary battery may be charged by sunlight by installing a solar panel near the detection sensor device, or may be charged by piezoelectric electricity by installing a pressure plate using a piezoelectric element on a nearby sidewalk.

The light emission sensor control unit 34 functions to control signal transmission and power transmission to each component in the light emission sensor, and a setting value for driving other devices is stored.

As an example, an illuminance sensor may be further provided in the detection sensor device 20 to determine whether the detection sensor device operates according to an illuminance value for an external environment. That is, in the daytime or in a state in which the street lamp is brightly turned on, the light emission of the light emitting display device does not have a significant effect, so that it does not operate, and in a state in which the street lamp is partially turned off at night, the device may be operated to achieve detection. At this time, the light emitting display device can be activated and operated according to the operation determination of the detection sensor device 20, and the determination of whether such operation is performed is determined by the light emission detection sensor 30 and the light reception sensor of the detection sensor device 20 ( 40) and the light emitting display device 60 may be transmitted to the other devices to be activated, or may be individually operated to perform an operation according to the activation.

However, when installed in a school zone, it is operated in the daytime as well as at night to ensure 24-hour sensing.

Next, the light receiving sensor 40 includes a light receiving unit 41 that receives the light irradiated from the light emission sensor, a light receiving sensor power supply 42 that supplies power to the light receiving unit, and a signal detected by the light receiving unit wirelessly. A light-receiving sensor wireless communication unit 43 for transmitting, a light-receiving sensor control unit 44 for controlling signals within the sensor, and a light-receiving sensor case 45 having a light incident hole through which the light irradiated from the light emission sensor is incident do.

The light-receiving sensor case 45 and the light-receiving sensor power supply 42 are provided in a structure similar to that of the light-emitting sensor case 35 and the light-emitting sensor power supply 32 of the light-emitting sensor 30 . However, the light receiving unit 41 checks whether the light irradiated from the light emission sensor continuously comes, and if a break occurs in the middle, it recognizes that the pedestrian has passed and generates a detection signal.

In addition, the light receiving sensor wireless communication unit 43, when a monitoring signal is generated in the detection process in the light receiving unit, transmits it to the light emitting display device so that the approaching vehicle driver by rapid light emission recognizes that there is a pedestrian crossing the road.

Next, the detection sensor device 20 basically sets the on/off time in the light emitting sensor control unit 34 and the light receiving sensor control unit 44 or a separate device to operate within the set time.

In addition, as shown in FIG. 3, a fog detection sensor 50 is further installed in the detection sensor device 20, so that the light emission sensor 30, the light reception sensor 40, and the light emission display device ( 60) can be turned on and off. Here, the operation by the fog detection sensor is set in advance so that the operation is made when the detection value is within the set value, so that the pedestrian information providing system for jaywalking can be operated even in an environment where visibility is not sufficiently secured by fog. .

4A is a schematic perspective view illustrating a light emitting display device according to the present invention.

As shown, the light emitting display device 60 includes a receiving portion 611 having an accommodation space formed thereunder, four pillar portions 612 extending upward from an upper edge of the accommodation portion, and an upper portion of the pillar portion. a main body 61 including a cover part 613 for covering, and a transparent window 614 that blocks the opening between the pillar parts to block the inflow of foreign substances from the outside while irradiating internal light to the outside; It is configured to include; a warning light 62 that is built into the space between the pillars of the main body to irradiate light to the outside.

The pillar part 612 prevents the internal warning light 62 from being damaged by the load applied when the vehicle steps on it, and provides a through hole between the pillar parts to radiate the internal light to the outside. In addition, it is desirable to prevent the tire from being damaged when the vehicle steps on it by forming all corners to be rounded.

The transparent window 614 is preferably made of transparent glass or transparent plastic that can easily transmit light and block external foreign substances. In addition, by attaching a coating film to the outer surface, it is possible to minimize damage to the outer surface of the transparent window when it collides with other objects.

In addition, the warning light 62 is installed inside the body 61, by installing a plurality of light emitting elements and equiangularly arranged based on the vertical so that light is irradiated to vehicles approaching from various directions, or one light emitting element is vertically arranged. It can be installed to allow light divergence to the side. Preferably, a plurality of light emitting elements are installed to focus and irradiate the light in the installed direction for each light emitting element, so that the light is transmitted to a long distance so that the approaching vehicle driver can sufficiently provide a time required to respond after recognition.

In the main body 61 accommodating part 611 of the light emitting display device, a light emitting display wireless communication unit 63 receiving a detection signal from the light receiving sensor, and a light emitting display power supply unit 64 for supplying power to each part of the light emitting display device and a light emitting display control unit 65 for controlling a signal inside the light emitting display device.

When the light emission display control unit 65 receives a detection signal through the light emission display wireless communication unit 63, the light emission display power supply unit 64 supplies power to the warning light to emit light.

Here, the light emission display control unit 65 cuts off the power supply to the warning light and supplies it, so that the warning light repeatedly flickers so that an approaching vehicle driver can easily recognize it. That is, as shown in FIG. 4B , a warning lamp 62 is disposed on the outer surface in the space between the cover part 613 and the receiving part 611 of the light emitting display device to irradiate light to the entire angle of the side surface, and the power supply is shortened. It can be cut and supplied so that light irradiation can be made in a flashing method.

4c is a vertical cross-sectional view of the light emitting indicator device according to the present invention, in which a vertical column 615 is installed, and warning lights 62 are disposed on both sides of the vertical column so that intensive light irradiation is made in both directions. to be. The warning light can be applied in various forms that can irradiate light to the side, such as a form installed on both sides of one support without a vertical pillar.

4D shows a light emitting display device in which the vertical pillar 615 on which the warning light is installed is rotatably configured. As shown, the vertical column 615 has an upper end rotatably coupled to the lower surface of the cover part 613 , the lower part of the vertical column 615 is rotatably supported on the upper surface of the receiving part 611 and the lower end is the receiving part (611) is formed extending inwardly, the lower part of the vertical column introduced into the receiving portion is installed with a gear, the vertical column 615 is gear-coupled with the operation motor 616 is rotated by receiving the power of the operation motor. As such, when the vertical pillar 615 on which the warning light 62 is installed is rotated, the irradiation direction is changed without blinking the warning light, so that the vehicle driver can be quickly recognized.

As shown in FIG. 5A , in the light emitting display device 60 according to the present invention, the light irradiation direction of the warning light 62 installed therein may be irradiated upward at a certain angle. If the light irradiation direction is formed upward at a certain angle, the range in which the light is emitted can be formed to be wide, so that it can be recognized even from a long distance. However, when excessively upwardly irradiated, the area of the light reflected on the ground is reduced, which may hinder the driver's recognition.

In addition, it is preferable that the main body 61 of the light emitting display device 60 is provided with a structure in which the vehicle wheels can easily ride and pass by forming the sidewall that is exposed to the top of the road as an inclined surface.

In addition, as shown in FIG. 5B , a solar panel 66 may be installed on the upper cover part 613 of the light emitting display device to charge the light emitting display power supply unit. Although the solar panel 66 is limited to only the cover part 613 , it can be separately installed along the central line of the road width on one side where the light emitting display device is installed, so that sufficient power can be supplied with only sunlight.

At this time, the light-emitting display control unit checks the charging efficiency of the light-emitting display power supply unit, and if the efficiency falls below a certain level compared to the time of the initial application, it sends a wireless signal to the facility manager for replacement, or emits light in a specific color at a specific time. It can be displayed externally to indicate that an inspection is required.

The jaywalking pedestrian information providing system 10 according to the present invention configured as described above can be constructed in a wide area such as a school zone even with a low installation cost by simplifying the structure as much as possible, and a vehicle driver approaching from a long distance when entering a pedestrian By sending a signal to the driver, sufficient time for braking is provided to prevent traffic accidents.

That is, in the process of the pedestrian entering the road to cross the road, the pedestrian is detected by the detection sensor device 20 installed on the roadside, and the detection sensor device 20 transmits the detection signal to the light emitting display device installed in the center of the road ( 60), and the light emitting display device 60 receiving the detection signal supplies power to the warning light 62 to emit light. The light emission of the warning light is made in the center of the road, and during the daytime, it is displayed as a twinkle to the driver, and at night, it can attract attention by reflecting light on the main surface. It is possible to provide a useful system for preventing traffic accidents by providing sufficient time to decelerate the speed of a vehicle crossing the road.
