Safety - related communications in closed transmission systems; Part 2. Safety-related communications in open transmission systems. This part is part 2 of GB/T 24339. This part is equivalent to the use of IEC 62280-2..2002 "Rail Transit Communications, Signaling and Processing Systems Part 2. Open Systems Safety related communications "(English version). The main differences between this section and IEC 62280-2..2002 are as follows. a) the word "international standard" is replaced by the words "this part"; b) Replace the comma as a decimal point with a decimal point "." c) prerequisites for the removal of international standards; d) Referenced documents ENV50129..1998 to EN50129..2003. Appendix A, Appendix B, Appendix C, Appendix D of this section are informative. This part is made by the Ministry of Railways.

GB/T 24339.2-2009/IEC 62280-2..2002IntroductionThe open transmission system consists of systems that are unknown or partially unknown, and this part is dedicated to safety related information in open transmission systems Interest transmission should be considered. If the safety-related electronic system involves the transmission of information between different locations, then the communication system becomes a safety-related system Components, and should be based on EN50129 end-to-end transmission is safe. The security requirements of the data communication system depend on their known or unknown characteristics. To simplify the complexity of proving system security methods, Consider two types of transmission systems. The first is a closed transmission system, its composition can be controlled by the safety system designer to a certain extent System, its safety requirements in GB/T 24339.1 requirements. The second is the open transmission system, GB/T 24339 of this part of the provisions Safety requirements for open transmission systems. This section considers the transmission system, and generally there is no specific prerequisite to be met. From the security point of view, the system is non-confidence Or not completely confident, is considered "black box". For crossacceptance for routine certification, not for special applications, the requirements shall be in accordance with EN50129 Requires the same. GB/T 24339.2-2009/IEC 62280-2..2002 Rail transit communications, signaling and processing systems Part 2. in the open transmission system Safety - related communication1 ScopeThis part of GB/T 24339 specifies the safety-related communications between safety-related equipment connected to an open transmission system. This requirement. Applicable to safety-related electronic systems for the purpose of communicating with the open transmission system and its safety requirements in order to The specified safety integrity level (SIL). The safety requirements specification is a prerequisite for the safety of safety-related electronic systems, and the evidence required for safety arguments (including quality Management and safety management, etc.) in EN50129..2003. The subject matter of this section is communication-related functional and technical safety arguments Claim. The nature and behavior of an open transmission system is used only to define features, not for security, and thus from an security perspective, The input system can be any potential, such as a variety of transmission methods, message storage, illegal access, security process can only rely on a variety of features, These must be stated in the security argument. This part does not apply to existing systems that have been adopted prior to the promulgation of this section. This section does not provide that. --- open transmission system; --- the equipment to which the open transmission system is connected; --- solutions (eg interoperability); Definition of safety-related data.2 normative reference documentsThe terms of this document are the terms of this part by reference to this part of GB/T 24339.
