GB/T 28808-2012 Railway applications—Communication,signaling and processing systems—Software for railway control and protection systems
Abstract
1.1 This standard specifies the procedures and technical requirements necessary for the development of programmable electronic systems used in rail transit control and protection equipment applications, and is applicable to any field with implied safety requirements. The scope of these application systems ranges from safety-critical systems (such as safety signal systems) to non-safety-critical systems (such as management information systems). These systems may be implemented using dedicated microprocessors, programmable logic controllers, distributed multiprocessor systems, large-scale centralized processor systems, or other structures.
1.2 This standard is only applicable to software and the interaction between software and systems.
1.3 Software safety integrity levels above Level 0 are used for systems where failures can lead to fatal consequences for humans. However, higher safety integrity levels can also be adopted based on economic or environmental factors.
