摘要

As rail transit technology advances, the demands for interoperability and compatibility in balise transmission systems continue to grow. The reduced size balise and standard size balise can no longer meet the positioning and wake-up requirements of automatic train supervision in urban rail. In this article, a generalized interconnection measurement model compatible with reduced size balise, standard size balise and expanded size balise are presented, and up-link signal characteristics of the air gap interface is analyzed. The feasibility of the model is validated by comparing calculating values for existing sizes against theoretical reference values in published standards. Subsequently, it’s applied to calculate reference values for the expanded size balise in the main lobe zone, which are validated through simulations and experiments with good consistency. Combined with experimental data and theoretical analysis, the model’s effectiveness is further proven in magnetic flux, loop current, uplink frequency, and amplitude properties of expanded size balise. The results indicate that this model not only provides reliable theoretical support for interoperability measurement of expanded size balise, but also offers critical references for system integration.
