Description

IOT-based snow melting system {IOT-based snow melting system}

The present invention relates to a road ice detection and prediction system using IoT. More specifically, based on IoT technology, actual road conditions such as road surface temperature, air temperature, humidity, and atmospheric pressure are measured and created into a database, and actual data and weather conditions are collected. This is about an IoT-based road ice detection and prediction system that prevents traffic accidents by identifying the correlation between data and providing road surface ice conditions in vulnerable areas to drivers.

With the development of science and technology, weather forecasting techniques are also steadily improving and fairly accurate weather forecasts are being made. However, the provision of information and forecasts about the road surface conditions on which cars actually drive are very weak.

In particular, in the case of Korea, which has a lot of mountainous terrain, there are dams, rivers, valleys, etc. around the roads that pass through, and there are many cases where roads pass through bridges or mountain ranges, so there are many vulnerable weather forecast areas where there are many differences from the general weather forecast. It exists.

In other words, the weather forecast vulnerable section often differs from the weather forecast of the Korea Meteorological Administration, and traffic accidents frequently occur for vehicles passing through this area due to insufficient road condition information for the weather forecast vulnerable section.

In particular, when the road surface freezes in winter, it causes a large number of traffic accidents, resulting in many casualties. Therefore, there is a need to quickly and accurately provide road surface condition information to vehicle drivers in vulnerable weather forecast areas.

As shown in Table 1 below, when the road is frozen, the friction between tires and the road surface is reduced, and the traffic accident rate is approximately four times higher on the frozen road surface than on the dry road surface. In addition, the traffic accident rate on the entire highway It was found that the proportion of accidents caused by road surface icing exceeded 14% of the number of accidents.

Likewise, not only is the traffic accident rate high depending on the road surface condition, but the fatality rate is also high, so it is most important for vehicle drivers to drive while accurately recognizing the icy condition of the road surface in winter. However, with the current weather forecast and road information, It is difficult to provide accurate information and forecasts for vulnerable sections of weather forecast, raising the need for countermeasures to be taken.

Of course, there are some examples of road icing warning systems that have been developed and installed in specific locations in the past, but the error range of road surface temperature is large, it is difficult to obtain accurate data on rainfall (snow, rain) and timing of rainfall, and solar power generation is difficult. The situation was that power supply was not being carried out smoothly due to the influence of weather, etc.

The present invention is intended to improve the conventional problems described above. It supplies permanent power using a hybrid power supply method and provides information about the road surface by obtaining accurate environmental information about the road surface in sections vulnerable to weather forecasting. The purpose is to provide an IoT-based road ice detection and prediction system that enables
