SMRT PSD Obstacle Detection methods
1. Optical Detection method
2. Driving motor(BLDC; Brushless Direct Current) surge current detection method
SMRT PSD Monitoring & Control Network
1. NOT USE the “Total surveillance control equipment” at each station office2. BUT, TCP/IP(ethernet protocol) network must be connected to platform or driver control panel to be centrally con-
trolled 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 equip-
ment is possible.

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
Man-Hour Reducing PSD Retrofitting Method
SMRT can do and is constantly Evolving for the future!!!
