The present invention relates to a road safety display device on a curve road, and more particularly, a road safety display device automatically operates when a driving vehicle enters or an opposite vehicle enters a steep curve road where forward observation is impossible. A road safety indicator is used to indicate a situation and call attention to a driver.

Automobiles are becoming an essential household item in modern life, and traffic accidents are increasing with the increase of automobiles. The main cause of traffic accidents is often caused by the driver's inadequate knowledge of the terrain, and especially when the driver is driving in an unfamiliar area, the driver may not be aware of the sharp curve ahead and may leave the road due to speeding. Happens a lot. Many road safety indicators are installed to prevent the accident by notifying the driver of the road condition on such a sharp curve in advance.

In general, the road safety display device installed along one side of the road to display the curve of the road is attached to the rectangular metal flat plate 1 as shown in Fig. (3) It is fixed to the upper side, and reflects the light of the vehicle to call the driver to be careful about the curve road, so that the driver prepares for the sharp curve ahead and prevents the vehicle from leaving the road. have.

The sign using the conventional reflector 2 is exposed to the outside, so that the oxidized or dust generated from the vehicle over time is accumulated on the surface of the reflector 2 as it is exposed to the outside, so it does not effectively reflect the light of the driving vehicle. It is impossible to properly perform the function of road safety signs, and the reflective paper 2 is cracked or easily damaged by the ultraviolet rays, which causes the problem of periodically repairing and replacing the reflective paper 2. In addition, road safety signs fixed to curves are installed so that the headlights are reflected to the driver when the vehicle is driving at night, and the reflection of the light is clearly recognized only when the vehicle is approaching the sign. This leads to a problem.

 In order to solve this problem, recently, safety signs using LEDs having excellent light emission have been developed to allow road drivers to recognize night signs clearly from a long distance. Signs using LED are superior in light emission compared to signs using reflective paper, so they can be recognized from a long distance and have a long service life.

However, LED signs require a separate power supply from the outside to emit LEDs, so it is difficult to supply power in mountainous areas with many curves. Regardless of whether the light continues to shine, there is a problem in that power consumption increases.

In addition, since the driver cannot observe in front of the vehicle at the sharp curve, it is embarrassing when another vehicle enters from the other side, and there are many accidents that even collide with the other vehicle. These conventional safety signs only provide information on the curve road for the vehicle in which the driver operates, and do not provide information on whether the vehicle enters the other side of the road on the curve road that is difficult to observe.

To this end, in addition to the safety sign indicating the direction of the road on the sharp curve road, a reflector 4 using a convex mirror is attached to the support 5 as shown in FIG. It is installed separately. The driver who enters in both directions of the curve road can recognize whether the vehicle on the opposite side is entering through the reflector 4, but the reflector also does not clearly display the information on the opposite side when dust or smoke on the vehicle accumulates on the surface. In particular, when the view is blurred or at night, it is more difficult for the driver to recognize the information on the opposite situation.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a safety display device for installation on a curve road in a mountainous region that is not easy to manage, and separate power from the outside using a solar cell. It is not required, and it is providing the road safety indicator on the curve road which is excellent in recognition with a driver using LED or an EL sheet.

It is another object of the present invention to provide a road safety indicator on a curved road that can reduce power consumption by installing a vehicle driving sensor at the bottom of the road so that the road safety indicator operates only when the vehicle passes. .

It is still another object of the present invention to provide a road safety indicator on a curve road that can recognize whether the vehicle enters on the opposite road together with the vehicle traveling direction on the curve road.

Still another object of the present invention is to provide a road safety sign apparatus on a curved road that prevents freezing of the road and prevents an accident on the curved road.

In order to achieve the above object, the road safety display device according to the present invention includes a sensor composed of first and second detection sensors for detecting a traffic of a vehicle in order to inform a driver of a situation about a sudden curve when driving on a curved road. And a power supply unit for supplying power to the road safety display device, and when the vehicle traffic is detected by the first detection sensor, and when the vehicle traffic is detected by the second detection sensor, the lamp is turned off while the vehicle passes. The first light source that is only turned on, the control unit for performing a series of processes of flashing the light source by the signal of the vehicle detection sensor, the case in which the first light source and the control unit is built, attached to the front of the case to protect the inside of the case And a display panel for guiding a traveling direction of the vehicle by transmitting light of the first light source to the first display unit displaying the traveling direction of the vehicle. Along the periphery of the device is characterized in that comprises a guide portion composed of a flange for attachment to connect the case and the panel.

In addition, the road safety indicator of the present invention, the third and fourth detection sensors for detecting whether the sensor enters the vehicle on the opposite side in order to inform the driver whether the opposite vehicle enters the curve road, and the guide portion is the first A second light source that is turned on when a vehicle traffic is detected by a three-sensor sensor, and is turned off when a vehicle traffic is detected by a fourth detection sensor, and is turned on only while the vehicle passes, and light of the second light source is transmitted to the display panel And a second display unit which displays whether the opposite vehicle has entered.

That is, in FIG. 6, the chevron-shaped display unit 37 flashes sequentially from right to left with respect to the traveling vehicle, and the vehicle-shaped display unit 38 sequentially moves from left to right when the opposite vehicle enters. It can be configured to flash.

7 to 9 are views illustrating a state in which a road safety display device is installed according to an embodiment of the present invention. FIG. 7 illustrates a state in which a road safety display device is installed on a curved road to guide a driving direction of a vehicle. 8 shows a state in which a road safety indicator is installed on a curved road that guides whether the vehicle enters the vehicle opposite to the traveling direction, and FIG. 9 shows whether the vehicle enters the vehicle opposite to the traveling direction in both directions. The road safety indicators on the guiding curve are shown.

Referring to FIG. 7, several guides 30 are installed at the edge of the road, and coil-type loop sensors 11 and 12 are embedded at the bottom of the traveling lane road to detect whether the vehicle 100 is traveling. do. The sensors 11 and 12 are preferably at least 50 meters away from where the first guide 30 is installed before the vehicle 100 enters the curve, ie in the direction in which the vehicle 100 travels ( d) buried in the first detection sensor 11 which is embedded in d) and detects the entry of the vehicle 100 in progress, and after the vehicle 100 passes through the curve, that is, where the last guide unit 30 is preferably installed. It consists of a second detection sensor 12 for detecting the passage of the vehicle 100.

In this configuration, when the vehicle 100 passes through the first detection sensor 11, the first light source 31 of the guide unit 30 is turned on and emits the chevron-shaped first display unit 37 to transmit the vehicle 100. ) Will indicate the direction in which it should rotate. In this case, when there are several light sources 31 (when there are several display units), the light sources 31 may blink alternately in the rotational direction to increase the recognition of the guide unit 30 to the driver. When the vehicle 100 passes through the second detection sensor 12, the first light source 31 of the guide unit 30 is turned off, and the road safety display device of the present invention stops the operation.
On the other hand, when two or more waves pass through the preceding vehicle passes through the first detection sensor 11 before passing through the preceding vehicle second detection sensor 12, the preceding vehicle is the second detection sensor 12 Even if it passes, the lighting state is maintained and turned off when the following vehicle passes through the second detection sensor 12.

When the opposite vehicle 200 passes through the fourth detection sensor, the second light source 32 of the guide unit 30 is turned off, and the road safety display device of the present invention stops the operation.

Accordingly, the driver of the vehicle 100 which is in progress on the curve road may know the direction of travel on the curve road by the first and second detection sensors 11 and 12, and the third and fourth detection sensors 13 and 14 may be used. As a result, it is possible to know whether the vehicle 200 enters the other side.

Referring to FIG. 9, the guide parts 30a and 30b according to the exemplary embodiment of the present invention simultaneously determine whether the vehicles 100a and 100b traveling in both directions enter the opposite direction and whether the vehicles opposite to each other enter the curved road. As you can see, it was constructed integrally at an appropriate angle according to the curvature of the road. In such a configuration, the first and second detection sensors 11 and 12 may include a first light source (see 31 in FIG. 4) of one side guide part 30a and a second light source of the opposite guide part 30b (FIG. 4).

It is connected to a light source (see 32 in Fig. 4). Accordingly, the vehicle 100a which is in progress on one side of the road is hit by the first and second detection sensors 11 and 12 on the curve along the traveling direction by the third and fourth detection sensors 13 and 14. It is possible to know whether or not the vehicle 100b enters on the side, and the vehicle 100b in progress on the opposite side uses the third and fourth detection sensors 13 and 14 to determine the traveling direction on the curve. The two detection sensors 11 and 12 may determine whether the vehicle 100a enters from one side.

However, the guides 30a and 30b may be separately installed at the edges of the road in the traveling direction to facilitate the driver's recognition of both vehicles 100a and 100b.

FIG. 11 is a view illustrating a state in which a road safety indicator further includes a heating coil for preventing freezing of a road according to an exemplary embodiment of the present invention.

Many accidents are caused by the freezing of winter roads, especially on curb roads. For this purpose, the road sign indicates that the freezing section of the curve road is frequent during the winter, but the driver notices that the road is frozen on the curve road or the slope road. There are many cases that cannot be prevented.

Referring to FIG. 11, in the road safety indicator of the present invention, a heating coil 19 is embedded in the floor of the road. As the power supplied to the heating coil 19, a solar cell is used. In this case, the heating coil 19 uses a heating coil for low power consumption for efficient power consumption.

As described above, according to the present invention, it is possible to install on a road where power supply is difficult because no separate power source is required from the outside by using a solar cell, and a driver driving at night using LED or EL sheet as a light source. Awareness of road safety indicators can be raised.

In addition, according to the present invention it is possible to reduce the power consumption by installing a vehicle driving sensor at the bottom of the road to operate the road safety indicator only when the vehicle passes, the driver on the road opposite the direction of travel on the curve road Can see at the same time whether or not to enter the vehicle, defensive driving can prevent accidents on the curve.

In addition, heating coils using solar cells can be buried at the bottom of the road to prevent accidents caused by freezing of the road in winter.
