Description

SMART ROAD REFLECTION MIRROR}

The present invention is coupled to the reflector unit and includes a main sensor unit that detects objects entering from one passage direction and the other passage direction according to a measurement control signal, and measures and provides at least one of the distance, speed, and position of the detected object. It is installed inside the enclosure coupled to the support, and detects and measures objects entering from one passage direction and the other passage direction at the point where the road reflector is installed through the main sensor unit. If the measured value is within the preset standard value range, By emitting light from the light emitting unit provided around the reflector, storing and supplying generated power through solar power generation from the power supply unit provided at the top of the reflector or other street lights, or supplying commercial power, the road reflector is easily operated while operating at low power. This is about a smart road reflector that can not only recognize objects, but also effectively provide warnings in situations where objects enter from both sides, preventing accidents in advance.

As is well known, the supply of vehicles is increasing day by day, and they are used as an indispensable tool in modern life.

However, in a country like Korea with a small land area, the reality is that road conditions are quite poor compared to the rapidly increasing number of vehicles. In other words, there are many difficulties in terms of securing the budget and available land area to expand various road networks, including highways, in line with the speed of vehicle penetration, and the number of regulated traffic safety facilities that can be installed in intersections such as alleys is limited. am.

Traffic accidents due to poor road conditions occur every year, especially in curved sections of mountain areas, non-signalized intersections, alleys without lanes, tunnel areas, construction sites, parking lots, etc., due to the driver's lack of visibility on the road. By installing convex mirrors at blind spots on roads and passageways where accidents occur frequently, road reflectors are installed in accordance with the road safety facility installation and management guidelines so that drivers or pedestrians traveling on the opposite side can identify vehicles or pedestrians entering the blind spot. there is.

In places where these road reflectors are installed, it is possible to prevent accidents in advance by not only checking the road conditions on the side you are turning in advance, but also making drivers on the other side aware of your presence.

However, these road reflectors are difficult to see at night, and even during the day, when the weather is bad, such as cloudy or heavy rain, it is difficult for drivers to check the road conditions. If road reflectors are used for a long time, frost and condensation may occur. There is a problem that occurs frequently.

In addition, there is a demand for the development of technology to prevent accidents in advance by installing object detection sensors on road reflectors to inform the vehicle of entry when an object is entering from the opposite side when entering or approaching the reflector.

The communication network 400 may include, for example, a mobile communication network, a wired Internet communication network, a wireless Internet communication network, a broadcasting network, an administrative network (closed network), and specifically a personal area network (PAN), a local area network (LAN), It may include one or more of the following networks: CAN (campus area network), MAN (metropolitan area network), WAN (wide area network), BBN (broadband network), Internet, LoRaWAN, bus network, star network, ring network, etc. It may include one or more of network topologies including networks, mesh networks, star-bus networks, tree networks, hierarchical networks, etc.

Through this communication network 400, a communication environment for wired and wireless data transmission and reception between the smart road reflector 100, traffic monitoring server 200, and manager terminal 300 can be provided.

Therefore, according to an embodiment of the present invention, it is coupled to the reflector unit to detect an object entering from one passage direction and the other passage direction according to a measurement control signal, and measure at least one of the distance, speed, and position of the detected object. and a main sensor unit provided, and is provided inside the enclosure coupled to the support unit to detect and measure objects entering from one passage direction and the other passage direction at the point where the road reflector is installed through the main sensor unit, and the measured value. If it is within this preset standard value range, the light emitting part provided in the periphery of the reflector part emits light, and generated power is stored and supplied through solar power generation in the power supply part provided in the upper part of the reflector part or in other street lights, or supply commercial power, thereby reducing low power. It not only allows easy recognition of road reflectors, but also effectively provides warnings in situations where objects enter from both sides, preventing accidents in advance.

In the above description, various embodiments of the present invention have been presented and explained, but the present invention is not necessarily limited thereto, and those skilled in the art will understand various embodiments without departing from the technical spirit of the present invention. It will be easy to see that branch substitutions, transformations, and changes are possible.
