IEEE 1482.1-1999

This standard covers on-board deviceds/systems with crashworthy memory which record data to support accidental incident analysis for rail transit vehciles. this standard is limited to event recorder functions and interrfaces, exclues the data transmission methods and is independent of the hardware and/or software employed for other vehicle systems. this standard identifies functions, parameters, signals, systems and subsystems which shall be captured. Diagnostic features or self-test options are described There is currently no defined, independent standard defining event recorders for rail transit vehicles. Each order of new vehicles or overhaul of old rail transit vehicles requires engineering effort by all parties to determine which signals to capture, how often to sample and how long to preserve the information, requiring a learning curve in this area for every project. Users of this standard will include those who specify, purchase, design and build rail transit vehicles and their subsystems. They will all benefit from a simplified process of integrating diagnostic information from multiple subsystem suppliers. New IEEE Standard - Superseded. On-board devices/systems, with crashworthy memory, that record data to support accident/incident analysis for rail transit vehicles, are covered. The requirements of this standard are limited to event recorder functions and interfaces. Data transmission methods are excluded. The information in this standard is independent of the hardware and/or software employed for other vehicle systems.
