T/SHJX 050-2022 TACS System Scenario Specification

Scope

Main technical content: The purpose of preparing this specification is to standardize the train autonomous operation system (hereinafter referred to as "TACS") as a new generation of train operation control system, which has the characteristics of safety, high efficiency, flexibility, economy, and easy deployment. The system has better functions and performance and a simpler architecture, which is different from the traditional CBTC system. At present, there are no relevant standards in China. In order to provide strong support for the construction and operation of fully automatic operation lines based on TACS, it is necessary to conduct in-depth research on the line operation scenarios and clarify the operational requirements of fully automatic operation based on TACS. This specification, as one of the main contents of the planning of fully automatic operation based on TACS, plays an important guiding role in system function allocation, system design, operation process, and the preparation of operational rules. At the same time, it can also provide guidance for the subsequent standardization of research, construction, acceptance, operation, and maintenance of fully automatic operation lines based on TACS. This specification includes: scope; normative reference documents; terms and definitions; abbreviations; normal scenarios; fault scenarios; emergency scenarios; and clause explanations. During the preparation of this specification, extensive investigation and research were carried out. Based on the current relevant national and industry standards and norms, opinions and suggestions from relevant units such as urban rail transit engineering construction, design, operation, management, and scientific research were actively adopted, and closely combined with the system characteristics of TACS and the characteristics of urban rail transit engineering in Shanghai, which is innovative and forward-looking.
