Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 2 of GB/T 32588.GB/T 32588 has been published in the following parts.

--- Automation of rail transit - Safety requirements for urban rail transit (AUGT) - Part 1: General;

--- Automated guided transport for rail transit (AUGT) Safety requirements Part 2: System level hazard analysis.

This document is modified to adopt IEC TR62267-2:2011 "Safety Requirements for Automated Guided Transport (AUGT) in Rail Transit Part 2 Part. System Level Hazard Analysis.

This document has many technical differences compared with IEC TR62267-2:2011.

A single vertical line (|) is used to indicate these technical differences. A list of these technical differences and their reasons is given in Appendix A.

Introduction

GB/T 32588 "Safety requirements for automated guided transport (AUGT) in rail transit" is intended to provide a common the security requirements for applicability are to help relevant organizations define appropriate security requirements for the AUGT they manage, and are composed of two parts.

--- Part 1: General. Aims to provide basic safety requirements based on existing AUGT operating experience.

--- Part 2: System level hazard analysis. Aims to support hazard identification, selection and combination of safety measures as a specific risk analysis basis.

In the AUGT system, automatic functions or other measures replace the functions that are performed by drivers and passengers in traditional rail transit systems.

GB/T 32588.1 lists the foreseeable risks, but does not provide detailed instructions on how to formulate safety measures for each identified hazard.

This hazard analysis and corresponding safety measures are essential for the design and implementation of the AUGT system.

It is particularly necessary to compile GB/T 32588.2, the system-level hazard analysis and response specification of AUGT.

This document conducts hazard analysis based on the basic functional requirements for train operation listed in Table 1 of GB/T 32588.1-2016.

Find out the relevant causes and triggering conditions of the hazards, provide corresponding safety measures and make a table.

Whether to implement the safety measure or assess the remaining acceptable risk. Use a safety measure or a combination of safety measures, or no safety measure at all the specific risks in train operation are dealt with according to the risk tolerance. This risk tolerance is assessed through specific risk analysis.

Therefore, this document does not judge whether it is necessary to use a safety measure or combination of safety measures.

The generic hazard analysis and the safety requirements obtained in this document support the system life cycle specified in GB/T 21562-2008 activities, applied to rail transit including AUGT systems. In order to facilitate specific risk analysis and determine system requirements, the identified Hazards, corresponding safety measures and methods are used as a guide to verify the environmental conditions for a specific system.
