Rail Solutions
Integrated Rail Communication, Passenger Information and Video Surveillance System
DTI offers a comprehensive, integrated rail data recording and train systems management unit that delivers the core operating functions of multi-camera CCTV recording, train audio communications recording, train operational data recording and external device control, GPS based rail locating, intelligent audio message announcements, multiple electronic signage control and route or stopping pattern management.
Video Surveillance Recording
DTI’s Data Recorder Unit incorporates a multi-camera CCTV recording sub-system. The DRU is equipped as standard with 8 video input channels. The camera frame rate can be remotely configured and customised for each camera channel.
Security information including train and camera identification details, train location (GPS), speed and heading are stored with each recorded image for the purpose of image authenticity testing.
Train Data Recorder (TDR)
A comprehensive range of configurable auxiliary inputs are available for the acquisition and recording of continuous train operating data including RS-232/RS-485 (2 x ports), USB 1.1 (2 x ports), analogue (8 x 0-5/10/30 volt range, over voltage protected inputs) and contact closure type device interfaces (16 x optically isolated inputs).
All I/O input channels (contact closure) to the TDR can be configured as security event triggers. Reactions to detected input event conditions are user configured and may be set to trigger or control other external devices or to archive a segment of train and CCTV data. A typical reaction to an input event may also include the playing of a message announcement or triggering of an output relay (i.e. warning light or alarm).
Passenger Emergency Intercom
The Passenger Emergency Intercom (PEI) operates with the passenger PEI activation button being monitored through the TDR and initiating an alarm recording event once pressed.
On detection of a PEI activation, a user configured segment of train data (normally 5 minutes pre and 5 minutes post PEI press) is quarantined, protected and then automatically downloaded on return of the train to base. The downloaded PEI alarm recording can be configured to include any or all of the parameters of CCTV, audio and TDR data inputs.
Driver Display Unit
The Driver Display Unit is a colour TFT LCD flat panel display with integral touch screen for easy use by train operators. The screen offers a resolution of 800 x 600 pixels and an active display area of 10.4 inches.
The screen housing can be specially fabricated to ensure optimum location in the train cowling area and for access by the driver.
Destination Indicator
The Destination Indicator uses a very wide viewing angle, high contrast and low power consumption LED’s. These Route and Destination signs are currently being used on many of the Australian and European Trains, Trams and Buses.
The DI utlises ultra-bright daylight viewable Amber LED’s which have a wide viewing angle of 160 degrees. The DI has a Built in Ambient Light Sensor, which guarantees excellent visibility in all lighting conditions, both day and night.
Passenger Information Display
The Passenger Information Display is a Multicolour sign capable of displaying text and graphics. It receives messages via a RS485 link.
The PID is a 96 x 16 pixel Matrix with 3 basic colours and contains 9 available fonts.
