On-board ATC System Design of Sao Paulo Line 13, Brazil.

This paper introduces the general situation of urban rail transit in Sao Paulo, Brazil, and describes the signal system and system composition of Sao Paulo Metro Line 13. The on-board signal system of this line is analyzed in detail, and the system composition, driving modes and main system functions of on-board ATC are analyzed and discussed. The receiving and processing function of track circuits, the speed monitoring function of release speed and the monitoring function of train braking force are analyzed in detail, and a design scheme is proposed.
