Mevcut telsiz sistemini kullanarak haberleşme tabanlı tren konum kontrol sistemi

In all railway communication system, radio device is commenly used. In open area data communication is achieved by RF transmitters/receivers and in closed enviroments like tunnel through a leaky feeder cable. Signalling systems are designed for vehicles with specific technology on the railway. Not every vehicle on railway can be monitored and this causes accidents. In addition, high-cost infrastructure is required for instant vehicle tracking in buildings such as tunnels. In this study, a railway vehicle tracking system is introduced and designed which enhances system security and minimizes data loss, using the existing radio infrastructure for communication in railway systems. In this thesis, location information was obtained with the axle counter sensors on the vehicle and the rfid transmitter circuits on the line. All railway systems have radio infrastructure and communication is provided in tunnels using 433 MHz transceiver circuits suitable for this infrastructure. 2.4 GHz transceiver circuits were used to back up this location information. All these systems are practical, cost-appropriate and designed to be installed on every vehicle. Consequently, instant tracking of every vehicle on the railway will be possible. As a result of this study, the location information of the vehicle cruising on the line is displayed instantly in the mapping interface located in the control center. When any of the transceiver circuits operating at 433 MHz and 2.4 GHz frequency band is off, data can be obtained from the other frequency band without data loss. In this way, vehicles can be tracked instantaneously and the system can operate as a redundant system itself.
