AI Technical Summary

Technical Problem

The prior art is difficult to effectively detect and locate abnormal electromagnetic interference around the transponder, resulting in difficulty in troubleshooting.

Method used

A detection system including a first electromagnetic signal detection unit, a second electromagnetic signal detection unit, a switch unit and a processor unit is designed. Through the 27MHz electromagnetic signal receiving coil and the 4.2MHz electromagnetic signal receiving coil, combined with the self-restoring fuse and the processor unit, the detection and alarm of electromagnetic interference around the transponder are realized.

Benefits of technology

It can effectively detect abnormal electromagnetic interference in the frequency band near 4.2MHz around the transponder, and send out an alarm signal when an abnormality is detected, simplifying the troubleshooting process. At the same time, the detection is suspended when the train passes to reduce the impact on communications.
