Supervisory Monitoring of Railway Signalling Devices by Spying Technique

스파잉 기법에 의한 철도신호제어설비 집중감시기법

This paper presents a method to construct a supervisory monitoring system for railway signaling devices which can provide the real-time operation information of signalling devices to several maintenance depots. Spying technique has been applied to acquire the real-time data transmitted among railway signaling devices without interfering the railway signalling system function.
