9 is a circuit block diagram of the present invention;

The component of the present invention includes a first support (10) largely embedded in the ground, a second support (20) for impact relief attached to the front surface of the first support, and a guide rail (30) coupled to the second support. ), A shock absorbing panel 40 installed to cover the front surface of the guide rail, a fluorescent fiber 50 installed on the front surface of the synthetic resin, and a shock sensor 60 installed on one side of the guide rail. ), The flare 70 is operated in conjunction with the impact sensor, the illumination sensor 80 installed on the first pillar, the control unit 90 and the power supply means (100).

The first support 10 may be manufactured in the form of a cylindrical or polygonal cylinder, but in the embodiment of the present invention, the first support 10 may be manufactured in a rectangular parallelepiped type for bonding with the second support. In addition, the first support 10 is embedded in the ground and is usually fixed by concrete pouring so that it does not fall easily to external impact.

The second support 20 is formed in a cylindrical or elliptic cylindrical shape of one side is open, coupled to the side of the first support 10 by bolts 22, respectively, made of the cylindrical or oval cylinder for shock mitigation The space portion 20a is formed to serve to absorb shocks due to the space portion 20a during a vehicle crash.

The guide rail 30 is bolted to the front surface of the second support 20, and the concave portion 30a and the convex portion 30b are repeatedly made, and the concave portion 30a is bolted to the second support 20 It is configured to be coupled to (31). In other words, the bolt 31 does not enter the outside and is not in direct contact with the vehicle.

The shock absorbing panel 40 is made of synthetic resin and is designed in a honeycomb structure to provide a primary shock protection function when the vehicle collides with the guide rail. When delivered, it is broken so that the shock applied to the vehicle can be absorbed first.

The fluorescent fiber 50 is installed on the front of the shock absorbing panel 40, it is preferable to form a concave channel in the convex portion (30b) for easy coupling of the fluorescent fiber (50).

Accordingly, the fluorescent fiber 50 is embedded in the concave channel to have a cleaner appearance, and the external vehicle can more clearly recognize the presence of the guide rail due to the light emission of the fluorescent fiber.

The impact sensor 60 is installed on the front surface of the convex portion 30b of the guide rail 30 or inside the second support and senses the impact when the vehicle comes to the guide rail 30.

The flare 70 is connected to the impact sensor 60, and provides an illumination in the event of a shock above the standard to prevent secondary accidents caused by not following the vehicle to observe the accident vehicle. .

The flare 70 is guided to ensure the ambient light of the accident vehicle, for this purpose, in the present invention, if a shock occurs more than a predetermined time by firing the flare 70 to allow a predetermined time to shine around.

The flare 70 also includes a housing 72 having a vent hole in the cartridge container 71. One end of the flares is sealed by the front closure 73. The opposite end of the front closure is provided with a rear closure 74, an ignition system 75 with an ignition agent, a protective cap 76 and a piston 77. In a preferred embodiment, the solidified (extruded) ignition stick 78, which may be hollow or empty, extends longitudinally (in whole or in part) through the propellant particles. The ignition stick is surrounded by propellant composition 79. Accordingly, when the ignition is started by the ignition system, the propellant composition 79 and the ignition medicine stick 78 are ignited, and then the housing 72 is triggered by the propellant composition 79 and at the same time, the ignition medicine stick 78 is released from the ground. Bright light is irradiated at a certain height. Of course, it is possible to add a parachute-like structure inside the flare 70, and the configuration of the flare with the ignition system 75, the propellant composition 79 and the ignition stick 78 as described above is no longer a general technical configuration The description is omitted. That is, the present invention is not in the flare 70 itself, but is a concept of firing the flare 70 by the control unit 90 according to the degree of the impact sensor 60, and is not an invention of the flare 70 itself. Known flares are used.
For reference, the ignition system is to output an ignition signal by inducing an electrical spark by an electrical control signal, and also consisting of a primary coil and a secondary coil, to produce an electrical spark by inducing a high voltage from the secondary coil The spark ignites the propellant composition and the ignition stick. As described above, inducing and igniting an electric spark according to a high voltage is only a very general technical idea. In addition, such an ignition system is widely used in an ammunition projectile that emits ammunition by electrical control, a firecracker projectile that fires firecrackers by electrical control, or an airbag system that inflates an airbag by electrical control.
That is, by applying an electrical signal to the ignition system by the control action of the control unit to be described later to induce an electrical spark in the ignition system, the propellant composition is ignited while the housing is launched, and at the same time the ignition stick stick is ignited from the bottom to a certain height The light is output to the outside, and the ignition system itself is a concept known as an electronic control trigger, so the description thereof is omitted.

The illuminance sensor 80 transmits data to the controller 90 by checking the current amount of light so that the flares can be ignited only in the dark night.

The controller 90 is connected to an impact sensor to calculate an impact amount generated when the vehicle collides with the guide rail, and when an impact above a reference level is detected, the control unit ignites the flares to fire.

The power supply unit 100 transmits electrical energy to the flare 70, the control unit 90, the impact sensor 60, and the illuminance sensor 80.

Looking at the assembly method of the present invention configured as described above are as follows.

First, the present invention embeds the first post 10 in the ground. The first support 10 may be manufactured in a cylindrical or polygonal cylinder, but in the present invention, the first support 10 may be manufactured in a rectangular parallelepiped cylinder for maximization of bonding with the second support 20.

The first support 10 is usually embedded in the ground by concrete pouring, and in the present invention, the first pillar 10 is embedded in the ground by concrete pouring.

When the first support 10 is embedded as described above, the second support 20 is attached to the front surface of the first support. One side of the second support 20 is open and has a flan surface 21 on both sides, and the flan surface 21 is padded on both sides of the first support 10 and then bolted to 22. Secure it.

At this time, the lower portion of the second support 20 is padded with a rectangular facet 23 and fixed to the ground with bolts 24.

As described above, since the second support 20 is fastened to the first support 10 by the bolts 22, the second support 20 may be assembled with the first support 10 very conveniently. When the support 20 is crushed, the bolt 22 may be dismantled so that the second support 20 can be easily disassembled from the first support 10 to couple the new second support to the first support.

When the first support 10 and the second support 20 are installed as described above, the guide rail 30 is installed, and the guide rail 30 has the concave portion 30a and the convex portion 30b continuous. It is a form, and the said recessed part 30a and the 2nd support | pillar 20 are fixed by bolting.

In addition, the convex portion 30b is installed to surround the shock absorbing panel 40, and the shock absorbing panel 40 has a honeycomb structure on its front surface, so that the vehicle easily collides from the outside. As it is broken, it can easily absorb the impact of the vehicle crash.

In addition, the fluorescent fiber 50 is attached to the front surface of the shock absorbing panel 40, and the fluorescent fiber 50 is preferably attached in advance when the shock absorbing panel 40 is manufactured. Of course, the fluorescent fiber 50 may be embedded after the impact absorbing panel 40 is installed.

In addition, the impact sensor 60 is installed on the inside of the second support 20 or the guide rail 30, and guides the electric line to the first support 10, and supplies power to the inside of the first support 10. It is provided with the means 100 and the control part 90, and is equipped with the flare which operates by the control of the said control part 90.

In addition, an illumination sensor 70 is further installed on the first pillar 10 to induce the flare 70 to operate only at dark night.

Hereinafter will be described in more detail with respect to the operation of the present invention.

The guide rail device of the present invention, the first support 10 and the second support 20, the guide rail 30, the shock absorbing panel 40, the fluorescent fiber 50, the impact sensor 60 ), The illuminance sensor 80, the control unit 90, and the flare 70 are basically configured. According to the present invention, when the vehicle collides with the guide rail 30, the secondary shock may be alleviated at the guide rail 30, and the third pillar may be alleviated at the second support 20. ) Is designed to mitigate the impact of a four-car collision.

In the present invention, when the vehicle collides, the impact absorbing panel 40 is first contacted, and the shock absorbing panel 40 is designed to have a honeycomb structure to easily absorb the impact of the vehicle while being easily damaged. It was.

In the present invention, since the guide rail 30 is formed in a concave-convex shape in which the concave portion 30a and the convex portion 30b are continuous, when the vehicle collides with the guide rail 30, the convex portion 30b is retracted. Secondly it will absorb the impact of the vehicle.

In particular, in the present invention, since the second support 20 is formed in an elliptical cylindrical shape, if the impact applied to the guide rail 30 is greater than or equal to the predetermined length, the second support 20 is crushed and the impact caused by the collision of the vehicle is once again. Therefore, since the vehicle can absorb the maximum impact over the third car, the impact on the inside of the vehicle is reduced by that much, and the impact on the occupants in the vehicle is reduced by that much.

That is, in the related art, since the guide rail is in the form of a waveform, the vehicle cannot absorb the shock properly, so that the vehicle is often bounced off after receiving the guide rail, which causes the vehicle to collide with another vehicle without steering properly. In the present invention, the shock absorbing panel 40 is installed on the front surface of the guide rail 30 so that the shock absorbing panel 40 is damaged and absorbs the vehicle shock primarily. And, because the guide rail 30 is made of a concave-convex shape, the convex portion 30b is retracted as it is retracted, and further buffered at a third time by the second support 20, thereby maximizing the effect of the buffer. It is.

In addition, the present invention is to ensure that the flare 70 is fired at a certain height when the impact is more than a predetermined time to light the fire at a certain height so that the vehicle occupants can rectify the accident without embarrassment, and also the vehicle ahead of the following vehicle Be aware of the situation to prevent secondary accidents.

In more detail, when the vehicle collides with the guide rail 30, the impact amount applied to the guide rail by the impact sensor 60 may be measured.

When the amount of impact generated while colliding the guide rail 30 is less than the reference, it is recognized that the guide rail 30 is slightly impacted, and no special measures are taken.

That is, for example, when the vehicle collides with the guide rail 30 at 30 Km or less, the airbag inside the vehicle does not burst and the guide rail is lightly in contact with the vehicle. Because there is no.

Then, if the amount of impact generated while colliding the guide rail 30 is higher than the reference, it is determined that the vehicle is no longer difficult to operate, and the flare 70 is operated to inform that there is an accident vehicle outside.

Of course, the present invention is equipped with an illuminance sensor 80, so that the flare 70 in the dark night at a height up to a certain height to fall while illuminating the fire so that the following vehicle can sufficiently grasp the situation of the front car.

In addition, it is a matter of course that the flares can be fired at a predetermined interval by communication with the control unit 80 mounted on the guide rails 30 around.

That is, the control unit 90 further includes a communication transmission / reception means to enable communication with a nearby control unit by wireless or wired. Accordingly, one control unit 90 is confirmed that the vehicle shock is higher than the reference, and thus flares 70 When firing, the flare of the first pillar that exists next to a certain time after firing, and in this way can be designed to fire a certain number of flares sequentially.

As a result, the present invention effectively minimizes the impact applied to the inside of the vehicle by effectively buffering the guide rail when the vehicle collides with the guide rail, and fires flares only at night when a certain amount of impact is applied, thereby easily recognizing the accidental vehicle in the vicinity. We can prevent secondary accident enough.
