Description

technical field [0001] The invention relates to the technical field of icing detection experiments, in particular to an indoor experimental device for detecting icing on road surfaces. Background technique [0002] If the ground temperature is lower than 0°C, snow or ice will appear on the road, and road icing tends to occur during a period of time from November to April of the next year (that is, winter and early spring). In northern China, especially in the Northeast and northern Inner Mongolia, roads often freeze. Generally speaking, in the twelfth lunar month of winter, when there is a large-scale strong cold air activity that causes the temperature to drop (called a cold wave in meteorology), if it is accompanied by rain and snow, road icing is most likely to occur. [0003] The icing situation can be detected by the icing sensor, which is a sensor that detects the thickness of icing on the surface of aircraft, power lines, buildings and other objects. The icing signal...

Problems solved by technology

[0005] When the above-mentioned patents are in use, first, the above-mentioned patents use the precipitation system to simulate rainfall, and do not take into account that when there is a large-scale strong cold air activity that causes the temperature to drop, if it is accompanied by rain and snow, road icing is most likely to occur; Second, although there will be icing on urban roads, there are vehicles rolling over the roads from time to time, which will affect the icing of the roads. It is necessary to simulate the roads according to this situation and obtain detection data; third, Pedestrian roads and roads rolled by vehicles have different rolling conditions. Under the influence of cold air, the icing conditions are also different. situation analysis
