Electronic interlocking system
SSI System(Interlocking logic S/W) is a core train controlling system that allows train service to be safe by
collecting information around railroad and relevant operating control order.
SSI is designed with 2 out of 3 architecture for safety of signal controlling, and it always works with fail-safe.
Over decades, SSI system has been selected by all over EU and was also selected by Gyeongbu(Seoul~Busan) railroad as an electronic interlocking system
and this proves SSI's stabilities & reliability.
TFM system - TFM is a system that gets controlling order from electronic interlocking system to control the site facilities and then sends back the condition
of the site facilities to the interlocking device.
Main function modules in TFM are UM and PM.
UM(Universal Module) is an in/output interface module between electronic interlocking device and signaling device
(signal flag, interface relay, line circuit, turnout, heating device, LP, PSC etcs)
PM(Point Machine Module) is an in/output interface module between electronic interlocking device and point machine.
FEPOL(Front End Processing Operation Level) is a subsystem of IXL that does interface between devices.
Local data transmission system processes the controlling messages from CTC and LCP of railroad control center then it transmits those messages to SSI and ATC.
It also transmits collected information in SSI and ATC to CTC,
LCP and overall monitoring system.
Main controlling and Monitoring points Path Set-up/Removal, PM switching, monitoring track occupation, monitoring marker,
ZEP Set-up/Removal, ZCP Set-up/Removal, CPT Set- up/Removal,
Direction locking, speed limit Set-up/Removal etc
MJ81 electric switch machine
MJ81 is a stationary electric switch machine with high performance.
it has been used in France, Korea, and worldwide railroad.
It can be remotely controlled and installed on a sleeper or concrete track which supports switch blade.
MJ81 electric switch machine prevents switch blade from moving by locking at both sides of the machine.
It can be manually operated and operated effectively in various temperatures.
