Abstract
Official abstract text for this publication.
The present invention includes a telegraph controller and an FSK modulator that serve as a signal transmission unit that creates a checking telegraph that is different from a controlling telegraph and transmits the checking telegraph to a pickup coil, an FSK demodulator and a telegraph controller that serve as a signal reception unit that restores telegraph information from the checking telegraph received via the pickup coil, and a communication controller that compares transmission telegraph information included in a checking telegraph transmitted from the signal transmission unit with reception telegraph information restored from a received checking telegraph that includes the transmission telegraph information to verify a telegraph reception function on an on-board side.
First claim
Opening claim text (preview).
The invention claimed is: 1. An on-board transponder device that is applied to a train safety system, and transmits and receives a controlling telegraph used for train running control to and from a ground device via a ground coil coupled with a pickup coil, the on-board transponder device comprising: a signal transmission unit that creates a checking telegraph that is different from the controlling telegraph and transmits the created checking telegraph to the pickup coil; a sign…
