GROUND DEVICE FOR TRAIN CONTROL SYSTEM

摘要

Provided is an on-ground device with which it is possible to ascertain the position of each train and transmit train control signals to the trains, even if trains equipped with on-vehicle devices compatible with different train control systems are travelling on the same rail line (region). An on-ground device (1) receives a train detection signal (TD signal) from a train equipped with an ATC/TD on-vehicle device by means of loop coils (21 to 2m), and receives a train position signal from a train equipped with a CBTC on-vehicle device by means of railroad radios (6 to 6n). The on-ground device (1) ascertains the position of each train traveling along a route (R) on the basis of the inputted train detection signal and the train position signal, generates a set of control information for each train on the basis of the ascertained train positions, and converts the control information into ATC and CBTC signals. The ATC signal is transmitted to the loop coils (21 to 2m) by means of an information transmission unit (4), and the CBTC signal is transmitted by means of the railroad radios (6 to 6n).
