Abstract

The invention provides a black ice early warning device and a black ice early warning method, which relate to the field of traffic and transportation. According to the device and the method of the invention, the surface resistance and the road surface temperature of a to-be-detected road surface area and the atmospheric temperature above the to-be-detected road surface area are detected; if the surface resistance is in a preset threshold range, the change rate of the road surface temperature along with time and the change rate of the atmospheric temperature along with time in a preset time period are both smaller than 0, and the road surface temperature is larger than 0, the black ice forming future time is calculated according to the absolute value of the difference between the road surface temperature and the atmospheric temperature, the change rate of the road surface temperature along with time at the current time and the road surface temperature at the current time. The black ice early warning device and the black ice early warning method can calculate the black ice forming future time, a working staff is reminded to remove accumulated water or an ice water mixture before the black ice forming time or to provide a safety driving hint for drivers after the black ice forming time.

Description

Technical field [0001] The invention relates to the field of transportation, in particular to a black ice early warning device and method. Background technique [0002] Black ice is a visual expression describing the critical icing state or thin ice of the shallow layer of water on the road surface. It is characterized by the ice crystals of the thin layer of water accumulated on the road surface or the ice-water mixture of critical icing . The main reason and process of black ice formation is that the road surface forms a thin liquid layer on the road surface due to shallow accumulation of water or ground evaporating water mist and condensed water. These liquid layers in critical icing state usually just dent the rough surface of the road surface. Fill up or slightly higher than the road surface, when the road surface temperature is close to zero degrees or below zero, these liquid layers are in a critical state of condensation or ice or ice crystals. Because the black ice is ...
