The invention relates to the technical field of railway neutral section passing systems, in particular to an anti-interference vehicle-mounted inductor which comprises a shell and a magnetic sensor, a cover plate is clamped to the top of the shell, a fixing base for bearing the magnetic sensor is arranged in the shell, and the magnetic sensor is installed at the top of the fixing base. One end of the top of the cover plate is in threaded connection with an elbow convenient for leading out a cable; a signal output end of the magnetic sensor is provided with a leading-out cable connected with the signal processor, and the leading-out cable penetrates through the inside of the elbow; the constraint of application conditions of an existing vehicle-mounted sensor is broken through, the size of a magnetic field where the vehicle-mounted sensor is located is accurately recognized, effective signals of an automatic neutral section passing system are picked up, interference of small magnetic field signals around the vehicle-mounted sensor is filtered out, misoperation of the automatic neutral section passing system is prevented, and the state of the vehicle-mounted sensor can be output in real time.
