Research on Modeling of Radio Propagation in Vacuum Pipeline Scene

The low air resistance and low friction characteristics of vacuum piping make it a new type of transportation system. Due to the influence of the train body, the radio propagation in the vacuum pipe needs to consider the multipath loss of the train body reflection and the diffraction loss of the obstacle. According to the Huygens-Fresnel principle, this paper studies the application criteria of basic models such as vehicle reflection multipath interference and obstacle diffraction by using standard interference and diffraction algorithms for the propagation mechanism of radio waves in a limited space. A radio propagation model along the surface of the vehicle body based on the above algorithm is established, which can provide design references for engineering applications.
