Research on Antenna Parameter Optimization Scheme for Vehicle-Ground Induction Communication System in High-Speed Train Control Systems

This paper analyzes the design requirements of the vehicle-ground induction communication subsystem in highspeed train control systems. In response to the issue of weak communication signal strength between the vehicle and ground equipment due to the long distance between the vehicle transmitting antenna and the ground induction loop, which leads to high error rates and communication failures, the S-S type circuit topology model used in this system is first analyzed. Based on the constructed circuit model, the antenna part is isolated to build an antenna simulation electromagnetic model. A solution to improve the parameters of the vehicle-ground induction system antenna is proposed. The feasibility of the antenna improvement method is verified through physical testing, and the research results can provide reference for the design of various types of vehicle-ground induction communication system schemes.
