Description
Technical Field
The invention relates to a road active ice and snow removing sensing and heating start-stop control method, in particular to a road conductive ethylene propylene diene monomer composite material active ice and snow removing sensing and heating start-stop control method.
Background
In winter, the climate environment is severe in many places, the problem of snow and ice on roads is inevitable, the friction force between wheels and the ground is reduced, the braking distance is lengthened, particularly, the ice phenomenon is serious on road sections with certain longitudinal slopes, and the automobile is extremely dangerous when going up and down the slope. The common road snow and ice removing method comprises a man method, a mechanical method and a chemical method, which all belong to 'passive' snow and ice removing methods, and the method needs to be applied after snow on the road is frozen and has hysteresis. The application often occupies a traffic lane, and normal traffic operation is influenced. The manual and mechanical methods have the characteristics of long operation time, incomplete clearing and the like, the ice and snow melting effect of the chemical method is greatly influenced by the environmental temperature and the snow falling amount, and the long-term use causes serious pollution to the surrounding ecological environment.
In recent years, in order to achieve "active" ice and snow removal on roads, an electric heating deicing method is often adopted.
The conductive ethylene propylene diene monomer composite material is a novel composite material integrating heat production, heat transfer and heat insulation, is prefabricated and molded in a high-temperature and high-pressure environment, has the characteristics of super-strong bearing, high and low temperature resistance, corrosion resistance, good durability, low manufacturing cost, super lightness, easy construction and the like, and can be used for a long time in an environment with the lowest temperature of-60 ℃ and the highest temperature of 130 ℃. The heat insulating layer and the heat transfer layer enable heat generated by the heat generating layer to be transferred upwards in a directional mode, and loss of heat energy in downward diffusion is reduced. The heat-generating layer of the composite material has good resistance stability, does not change along with the increase of the service time, and ensures continuous and stable heat generation.
Conductive ethylene propylene diene monomer composite materials are often applied between a road surface layer and a base layer, conductive electrodes at two ends are connected with a power supply through leads, and under the action of an external voltage, a heat-generating layer generates heat through an electric heating effect, so that ice and snow on the road are melted by transferring the heat to the surface layer. Because the heat generated by the composite material needs a certain time to be transferred upwards to the road surface, the ice and snow can be quickly melted by starting in advance. When the road surface temperature reaches a certain value, the input power is often required to be stopped or reduced, and the loss of energy diffusion is reduced. The technical problem of how to control the start and stop of the heating system and adjust the input power is not solved.

③ the humidity is more than or equal to 90 percent or snowfall;
if the above three conditions are satisfied simultaneously, the heating circuit is turned on. The condition of starting the heating circuit considers two conditions of pre-heating (the humidity is more than or equal to 90 percent) before the snowfall of the road surface and the snowfall, and the air temperature T and the average temperature T of the road surface are used1The common judgment shows that the temperature of the road surface is low at the moment and the road surface is likely to freeze, so that the heating circuit needs to be started to improve the temperature of the road surface, and the real-time snow melting and the ice prevention of the road surface are realized.
