and an electromagnetic field intensity model construction module 350, configured to construct an electromagnetic field intensity model by taking the electromagnetic field data and the shape design parameters as input and the electromagnetic field intensity at each position as output.
The form design parameters generally include length, width, thickness maximum, curve radius, etc. In order to reduce the resistance caused by air, the top of the high-speed railway vehicle is generally arched, and the curve radius is the radius of a circle corresponding to the inclined plane curve of the cross section of the top of the high-speed railway vehicle. Appearance design parameters of the top of the high-speed railway vehicle can be obtained by checking design drawings of the top of the high-speed railway vehicle. Optionally, the three-dimensional image of the top of the high-speed railway vehicle can be drawn according to the design drawing of the top of the high-speed railway vehicle, so that the distance between each position of the top of the high-speed railway vehicle and the pantograph and the shell thickness of the top of the high-speed railway vehicle between each position and the pantograph are more visual and are easier to obtain.
The electromagnetic field intensity model can be a calculation model based on the structure and the function of biological neurons, the data processing and analysis are realized through the connection and the information transmission among a plurality of nodes, and specific nodes can comprise electromagnetic field data, appearance design parameters, electromagnetic field intensity of each position and the like.
The method for constructing the electromagnetic field intensity model can adopt a mode of selecting a proper neural network structure, determining the number of layers of the network, the number of neurons of each layer, an activation function and the like, initializing parameters of the model, calculating input data layer by layer through weights of all layers and the activation function according to the network structure, transmitting the input data to a preset output layer, and repeating the steps of forward propagation, calculation loss, reverse propagation, parameter updating and the like until preset stop conditions are reached. The input parameters may be sample electromagnetic field data and sample appearance design parameters, the preset output layer may be sample electromagnetic field intensity, and the sample electromagnetic field data, the sample appearance design parameters and the sample electromagnetic field intensity may be obtained by using a sample at the top of the high-speed railway vehicle to record electromagnetic interference experiments, or may be historical data obtained by measuring the top of the high-speed railway vehicle which is already put into use.
Optionally, the apparatus further includes:
the electromagnetic field strength estimation module is used for obtaining appearance design parameters of the top of the target railway vehicle and working parameters of the power supply cable in the running direction of the target railway vehicle; and calculating electromagnetic field data according to the working parameters, and determining the electromagnetic field intensity estimated results of all positions on the top of the target high-speed railway vehicle according to the electromagnetic field data and the appearance design parameters of the top of the target high-speed railway vehicle.

Furthermore, the calculation of the electromagnetic field data requires the conductor diameter and the insulation layer thickness of the power supply cable, the geometry and shape of the pantograph and the spacing between the pantograph and the cable.
The electromagnetic field data may be calculated by using a finite element method. This approach models the power cable and pantograph as geometric structures and then uses an electromagnetic field equation solver to calculate the electromagnetic field distribution. Common electromagnetic field equation solvers include, for example, COMSOL Multiphysics, ANSYS, CST Studio Suite, MATLAB, and the like. Specifically, the electromagnetic field equation may be a basic physical equation set describing the behavior of the electromagnetic field, and is composed of maxwell's equations and lorentz force law, which describe the generation, propagation and interaction of the electromagnetic field, and may be used to solve electromagnetic field problems, such as calculating electromagnetic field distribution, electromagnetic wave propagation, electromagnetic radiation, and the like.

The electromagnetic shielding film is coated around the communication cable, so that external electromagnetic waves can be absorbed or reflected, and interference to the communication cable is reduced. An electromagnetic shield is installed around the communication cable to provide a physical barrier against the intrusion of external electromagnetic waves. The top shell of the high-speed railway vehicle can be made of wave-absorbing materials, and the electromagnetic field strength can be weakened.
