In order to determine the correlation between the thickness of the ice layer, the movement speed of the heating body and the heating energy of the heating body in some embodiments of the present invention, as shown in fig. 2, fig. 2 is a schematic structural diagram of another embodiment of the road ice layer hot melt control system provided by the present invention, where the mapping module 100 includes a relationship building module 101, a model building module 102, a simulation module 103 and a data fitting module 104;
the relation construction module 101 is used for constructing the thickness grade of the road surface ice layer, determining the thickness range of the ice layer of different road surface ice layer thickness grades, and constructing an initial association relation function of the thickness of the ice layer, the movement speed of the heating body and the heating energy of the heating body under the different road surface ice layer thickness grades;

the data fitting module 104 is configured to perform fitting on the multiple sets of associated data to determine association relations between the thickness of the ice layer, the movement speed of the heating body and heating energy of the heating body under the ice layer thickness grades of the different road surfaces.
The road ice melting simulation comprises the following steps: and placing the heating body on the simulated frozen road surface to move at various fixed speeds, and adjusting the heating energy, and recording the thickness of the ice layer, the movement speed of the heating body and the heating energy when the interface adhesion disappears.
In a specific embodiment of the present invention, the relationship construction module 101 determines three ice layer thickness grades and an ice layer thickness grade range according to engineering practical conditions, and uses heating body heating energy P as a dependent variable, ice layer thickness h and heating body movement speed v as independent variables, to establish a binary primary piecewise function.
When the thickness h of the ice layer is less than or equal to h1, the thickness grade of the ice layer is h1, and the function is as follows:
P 1 ＝a 1 v+b 1 h+c 1 wherein a is 1 、b 1 、c 1 Is a coefficient to be determined;

the model building module 102 builds ice layers with different thicknesses and pavement structure layers, and enables the ice layers with different thicknesses to be placed on the pavement structure layers and to generate interface bonding, so that a plurality of groups of simulated frozen pavement models are built.
In a specific embodiment, in combination with the actual situation of road icing, taking an example that the thickest part of the ice layer of the road surface is 60mm, when the ice layer thickness is divided, the thickness range of the ice layer under each ice layer thickness grade is as follows:
the corresponding ice layer thickness range for thickness class h1 is (0 mm,20 mm);
the corresponding ice layer thickness range for thickness class h2 is (20 mm,40 mm);
