With new technology developing, subways and railways have been adopting more and more smart devices to enhance safety and to improve management level.
The functions include:
to monitor the train driver's fatigue status, distraction, and yawning.
to check the driver's semaphore before the train starts to move.
Abnormal conditions trigger alerts, visible and audible to remind the drivers, while reports with video footage are sent to the management center through subway intranet. This system has been certificated according to railway electronic OEM standards.
The system is installed on maintenance cart, to detect:
Abrasion of over-head power lines, at ±1.0mm.
obstacles infringing train track.
dropped screw/small stone on runway
ring power net overheat
The system consist of.
Host
thread Laser
multi-plane LiDAR
high-speed matrix camera + laser lights
infrared camera + wireless temperature sensor
RFID
the brain of Driverless-Train or Train-Driving-Assistance-System, is to
detect the obstacles that may threaten the train's approaching, including another train on the same track
and track-side items infringing the train's borderlines.
Interface with ATP (Automatic Train Protection system) to brake (option)
Electronic map from ATP to adjust to slopes and crosses (option)
Multi-plane LiDARs
Stand-alone system. Can work without trackside facility like radars
To ensure its security and reliability, this system is being designed, tested, and certificated at SIL2
standards (under certificating)
The system consist of.
other trains up to 200 meters
rail track up to 150 meters
box (30 x 30 cm) at 60 meters
people up to 80 meterss
