Maglev transportation is a new technology for urban rail transit; and its emitted constant magnetic field aff ects passive balise, which may cause additional risks to the safe operation of trains. This paper first analyzes the electromagnetic environment of balises, performs the disturbance test for the passive balise, and locates the sensitive parts of the device. It then puts forward such protection technologies as magnetic field dredging and angle optimization, according to the coupling characteristics of the constant magnetic field with the inductive parts, and conducts the eff ectiveness verification. This research achieves substantial improvement for the adaptability of the passive balise under constant magnetic field; and provides reference for the immunity of other train control equipment of the maglev system under constant magnetic field.
