17. SMRT PSD Monitoring & Control Network
1. NOT USE the “Total surveillance control equipment” at each station office
2. BUT, TCP/IP(ethernet protocol) network must be connected to platform or driver control panel to be
centrally controlled by adding a new DATA COMMUNICATION MODEM(compact size).
3. Also, regional grouping(4~5 stations) control by one representative station office’s Total surveillance
control equipment is possible.

18. Newly developed modular method
UNIT assembly at the factory
- Homogeneous quality
- Cost reduction by line production
Conveyance by motor car &
construction on the same day
- No piling up of materials
- No inconvenience to passengers
- No hindrance to train operation
**per 1 station

19. SMRT can do and is constantly
Evolving for the future!!!
