本标准涵盖了具有耐碰撞存储器的车载设备/系统，这些设备/系统记录数据以支持轨道交通车辆的事故/事件分析。本标准的要求仅限于事件记录器功能和接口，不包括数据传输方法，且独立于用于其他车辆系统的硬件和/或软件。识别应捕获的功能、参数、信号、系统和子系统。描述了诊断功能和自检选项。

This standard covers on-board devices/systems, with crashworthy memory, that record data to support accident/incident analysis for rail transit vehicles. The requirements of this standard are limited to event recorder functions and interfaces, exclude the data transmission method(s), and are independent of the hardware and/or software employed for other vehicle systems. Functions, parameters, signals, systems, and subsystems that shall be captured are identified. Diagnostic features and self-test options are described.
