Signal System materializes Full-Automatic Control System adopting Micro-Processor Computer that promotes safety and convenience of passenger and makes rolling stock fast and accurate high speed transportation.
ATP[Automatic Train Protection] System materializes function associated train safety.
All defects should be found and conduce to constrained situation.
ATO[Automatic Train Operation] System automates general function done by driver and
enables automatic & unmanned driving.
RF-CBTC[Radio-Frequency Communication Based Train Control] System controls train with real time
wireless LAN communication and realizes Distance To Go & Moving Block System.
We carry out not only research to secure and develop independent signal system but also interface design between signal device and vehicle.
