Description

{Active monitoring and control type safety lighting device}

The present invention relates to an active monitoring operation type safety lighting device for an icy road section, and more particularly, it is installed on the roadside to detect and determine whether there is icing and automatically turn on or blink the lamp to enable a driver to safely drive in an icy road section Therefore, it relates to an active monitoring control type safety lighting device that can prevent the risk of an accident caused by icing in advance.

In general, vehicle accidents due to road icing, called bla ice, occur frequently in winter. was investigated as

Most of the accidents caused by icing on the road lead to a series of multiple collisions, which is because, even after finding a stopped vehicle, the following vehicles slide on the icy road and collide with each other even if the brake is applied.

Therefore, when snow accumulates or the road surface is icy on roads such as bridges, tunnel entrances, curves or slopes, as well as roads icy in winter, it not only impedes vehicle traffic, but also increases the risk of collision accidents due to slipping accidents. Therefore, rapid snow removal and thawing must be carried out. As a method to remove snow from the road or thaw the road surface, a snow removal agent such as calcium chloride, a thawing agent, or a friction agent such as sand is sprayed on the road or snow removal equipped with a snow shovel. Another method is to use a vehicle to clear the snow to the side of the road.

However, such snow removal and thawing work must use a vehicle, and when manually spraying snow removal or thawing agent, a lot of manpower and equipment are required, so workability and economic feasibility are greatly reduced. There was a disadvantage that the thawing operation could not be dealt with quickly.

In particular, when the road surface is frozen like black ice, the road management company cannot confirm it in advance, so there is a problem in that it is not possible to perform the thawing work quickly and appropriately in reality.

To compensate for this problem, conventionally, there is a road management system that comprehensively calculates data for each section of the road using weather data, various sensors, image sensors, and geographic information systems, and transmits it to an electric sign installed on the side of the road to guide the driver. Although it has been introduced and operated, it is necessary to transmit the information detected from the sensors and image detectors to the server through the wired/wireless network, so the economic burden of introduction and operation is high, and in reality, sensors, image detectors and information for all sections of the road are transmitted. There was a disadvantage that it was not possible to install and operate the electric signboards that displayed it.

In addition, in the case of a road with infrequent traffic, there is a phenomenon that not only does the road surface freeze easily, but the duration of freezing is prolonged. This high problem remains.

The main body 10 forms an outer body and has a cylindrical shape with front and rear open sides, and a lamp housing 11 having a circuit board (not shown) and a battery (not shown) for charging and discharging therein, and the lamp housing A plurality of LEDs 15 provided on the front and rear surfaces of (11) to receive power and perform any one or two or more of lighting, blinking, and flashing operations, and provided at a position not to interfere with the location of the LEDs 15 It is composed of an optical module 13 composed of a light detection sensor 17 that detects the light of a headlamp irradiated from a passing vehicle at night.

The lamp housing 11 has a cylindrical shape with open front and rear surfaces, and in the present invention, it is exemplified that it is molded from a synthetic resin injection product. The lamp housing 11 is provided to reflect light by applying a chrome coating on the outer surface, and both sides of the open front and rear surfaces are shielded with a transparent lens cover (not shown) for diffusing light. And, a circuit board (not shown) and a battery for charging and discharging (not shown) are accommodated inside the lamp housing 11, and the optical module 13 is provided inside the lens cover.
