Abstract

An integrated type ATC (Automatic Train Control) system has been developed. An automatic train-protection function and interlocking function are executed on unified hardware of the ATC logic unit on the ground. Integration of hardware: makes the interface between conventional ground side ATC logic unit and interlocking device unnecessary; simplifies the input/output connection among the safety related facilities; and gives a space margin of a signalling cabin. Fully digitalized two-channel hardware architecture realizes a decrease in the number of electro-magnetic relays and of analog circuits being the bottleneck of reliability and availability of conventional train protection and interlocking facilities. The transmitter/receiver unit is mounted DSP (Digital Signal
