  14. 14. 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. Central control room Local maintenance office (Platform) Station Office Equipment Driver Control panel Platform Control Panel
  15. 15. 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
