Description

Flexible resistance rejection device for highway early warning Technical Field The invention relates to the technical field of highway early warning, in particular to a highway early warning flexible refusing device. Background In recent years, road engineering accidents and natural disasters are frequent under the influence of extreme weather and human factors. To cope with such dangerous situations, intelligent monitoring systems are commonly used today to monitor infrastructure structures in real time. However, after the monitoring system gives out the early warning, how to effectively warn the high-speed running vehicle in the upstream direction of the hidden trouble point and enable the high-speed running vehicle to slow down or safely stop, which becomes a difficulty. The traditional warning mode mainly sets up audible and visual alarm and LED display screen in infrastructure structure upstream direction, but because the noise that natural light is stronger in daytime, high-speed driving produced and the influence of vehicle sound insulation effect, the warning effect of sound and light discounts greatly, and secondly, the driver mainly still focuses on the road surface condition when driving, ignores the LED display screen on roadside easily.
