Escopo e aplicabilidade

This standard specifies the technical conditions for crossing signal equipment located within railway stations. It applies to various types of level crossings, including those in the station throat area and receiving-departure tracks. It is mandatory for all manufacturers and operators involved in station crossing safety systems.

Requisitos técnicos

The standard outlines the environmental conditions for equipment operation, including temperature, humidity, and vibration limits for both indoor and outdoor installations. Equipment must withstand harsh outdoor environments, with specific requirements for atmospheric pressure and vibration resistance. It defines the technical requirements for crossing signals, ensuring that road and railway signals cannot be activated simultaneously during train approach. Manufacturers must implement fail-safe principles for sensing and logic control. The standard also details the calculation methods for train approach warning times and approach section lengths, referencing Appendix A for specific formulas. Requirements for power supply reliability dictate that equipment must have uninterrupted power, with specific voltage tolerances. The standard specifies the visual and audible signaling parameters, including flash frequencies and sound levels compliant with GB 3096-2008. Additionally, it covers the setup of automatic barriers, control panels, and dedicated mechanical rooms. The standard introduces modern safety protocols, requiring compliance with RAMS specifications (Reliability, Availability, Maintainability, and Safety) according to GB/T 21562-2008, achieving a SIL4 level. Systems must also meet strict requirements for software safety, electronic systems, and electromagnetic compatibility.

Métodos de ensaio

The standard references several testing and evaluation procedures, including environmental condition testing (temperature, humidity, vibration), electromagnetic compatibility (EMC) testing per GB/T 24338.5-2009, and RAMS assessment for safety-related electronic systems. It also requires verification of fail-safe logic and signal timing calculations.
