Railway transponder radio frequency circuit parameter optimization method and system

The invention provides a railway transponder radio frequency circuit parameter optimization method and system, and belongs to the technical field of rail transit transponder equipment development and testing. Equivalence analysis is carried out on components in a high frequency circuit, key characteristic variables of the circuit are extracted, and a multi-objective optimization model of static power consumption and circuit cost is established; and performing parameter optimization on the multi-objective optimization model by using a genetic optimization algorithm. According to the method, the construction of a multi-objective optimization function is taken as a key starting point, and the whole process from feature vector selection to parameter optimization output is realized; a clear way is provided for reducing the power consumption and the circuit cost of an existing transponder circuit, so that the implementation of parameter optimization can adopt the ideas of multi-objective optimization and data drivi
