System and method for railway vehicle detection
First Claim
1. A method of detecting specific railway vehicle directional movement on a track section of a railway system, wherein a plurality of RFID readers are mounted on track and active RFID tags are mounted on the railway vehicles, and at least one central computing units for monitoring the network of readers, said method comprising:
- analyzing the link quality indicator (signal strength) received in the said reader determining the reception of tag identification signal;
reporting the arrival or departure nature of the said reader with the railway vehicle detection results to the central computing unit;
distinguishing the correct tag signal received from a couple of readers on a couple of tracks in proximity to identify specific railway vehicle.

Abstract
A system and method for detecting the railway vehicle with a plurality of RFID readers and tags are disclosed. Railway vehicle directional movement on specific track can be detected and updated by the RF communication of the readers and tags. The railway system also includes a computer which monitors a couple of RFID readers for the real-time railway vehicle position. Intelligent detection algorithm is implemented in the reader to identify specific railway vehicle, on a particular track for at least one track in bidirectional or parallel direction. For encoding the data, each RF tag is of unique ID and the RF signal is encrypted.
