[0108] Where V isolated is the output voltage after isolation; N primary and N secondary are the turns of the primary and secondary windings respectively; V input is the input voltage; this solution covers the electromagnetic, thermal field and isolation design of the device.

[0109] It should be further explained that the electromagnetic heating flat sensor system is designed for removing thick deck coatings. It uses a high-frequency electromagnetic field to produce precise and uniform heating of the coating to accelerate the softening and stripping process of the coating. The core structure of the system includes high-frequency resonant capacitors, high-frequency transformers, induction coils and front-end sensors. These components work together to ensure efficient and stable heating performance. The high-frequency transformer is not only responsible for voltage regulation in the system, but also achieves electrical isolation through electromagnetic induction, ensuring that the input and output parts of the circuit are not physically directly electrically connected, thereby effectively preventing safety hazards caused by electrical faults. The secondary side of the high-frequency transformer adopts low-voltage and high-current output, so that the induction head can maintain high-frequency and stable current conditions during operation, and the cooling system further controls the temperature of the induction coil to ensure the stability of the system under continuous high-load conditions.

[0110] In order to achieve the maximum power factor of electromagnetic heating, the system is designed with a parallel resonant circuit, which is composed of a high-frequency resonant capacitor and a load inductor mapped to the primary of a high-frequency transformer through equivalent transformation; the function of the inverter unit is to capture and stabilize the resonant frequency so that the inverter frequency matches the resonant frequency, thereby maximizing the power transfer efficiency; by adjusting the parameters of the resonant capacitor and the load inductor, the system can automatically adjust the resonant state under different load conditions to adapt to different coating thicknesses and material properties; this resonant frequency control mechanism not only improves the heating efficiency, but also ensures that the electromagnetic energy of the system can fully act on the target area during the coating removal process, achieving the optimal power factor; in this way, the energy loss is minimized and the power transfer efficiency is maximized when the system is working, providing stable power support for subsequent precise heating;

[0111] The finite element analysis auxiliary design module is used to simulate and optimize the distribution of electromagnetic fields and temperature fields to ensure the uniformity and control accuracy of the heating effect. In the system design stage, the finite element analysis module provides the best heating parameter configuration for the equipment under different operating conditions by accurately modeling the electromagnetic field and temperature field. Through finite element meshing and node calculation, the module can calculate the magnetic field strength, temperature distribution and current density around the induction head, so as to determine the optimal power density distribution under different load and environmental conditions. By real-time monitoring of the heat transfer in the heating area, the finite element analysis module provides an accurate feedback adjustment scheme for the temperature field, avoiding local overheating or insufficient cooling caused by uneven distribution of the thermal field, and ensuring that the induction head can evenly heat the coating surface. This module greatly improves the temperature control accuracy of the system, so that the coating can achieve a stable and efficient heating effect during the removal process.

[0112] In order to adapt to the complex surface structures in different areas, a movement and position adjustment mechanism of the induction head is designed at the front end of the system; the mechanism consists of horizontal and vertical guide rails, a drive motor and a positioning sensor, and realizes the precise positioning of the induction head through a two-dimensional moving path, so as to perform heating operations on the surface of complex steel structures; the horizontal guide rail is responsible for the left and right plane movement of the induction head, while the vertical guide rail is used to control the adjustment of its up and down height; through the drive motor, the induction head can achieve smooth two-dimensional movement in the horizontal and vertical directions, and the positioning sensor monitors the specific position of the induction head in real time, and feeds back the position information to the control system, so that the system can accurately fine-tune the position of the induction head according to needs; in this way, the system can accurately and evenly heat the coating areas of different thicknesses or shapes during the actual heating process, ensuring that each area can reach the required temperature level for removal;

[0113] In terms of material selection, the induction coil and the induction head are both made of copper to improve electrical and thermal conductivity. The high electrical conductivity of copper ensures the transmission efficiency of the high-frequency electromagnetic field around the induction head and reduces the loss of electromagnetic energy during the conduction process. At the same time, the system is designed with a composite cooling system to cool the induction coil through the cooling water circuit to control the temperature of the high-frequency current when it is working. The composite cable integrates the temperature sensor, speed sensor, main output cable and cooling water circuit, which not only simplifies the wiring, but also improves the system's integration and ease of operation. The water cooling system provides continuous temperature control during the high-frequency heating process of the induction head, avoiding the degradation of material performance due to excessive heating, while ensuring the safety of the system and the stability of operation.

[0114] In order to meet the needs of electrical isolation and high-power safe transmission, the system is designed with an electrical isolation structure; energy is transferred between the primary coil and the secondary coil of the high-frequency transformer through electromagnetic induction, avoiding direct electrical connection and ensuring complete isolation of the input circuit and the output circuit; when the system operates under high frequency and high current conditions, the secondary coil of the transformer can safely transmit large currents and stabilize its temperature through a water cooling system; when an electrical fault occurs in the system, the isolation design can effectively cut off the fault current and prevent the main circuit from being affected, thereby protecting the stability and safety of the entire system.
