    摘要: A Railway Signal Safety Communication Protocol I (RSSP-I) safety communication method based on dual-system synchronization belongs to the technical field of safety communication, and includes: adopting 0×01 for both main machine and standby machine protocol interaction types in a message header of a Real-time Safety Data (RSD) message, and adopting 0×82 for both message types of a main machine and a standby machine; changing data sent by the main machine and the standby machine into a plurality of copies of completely same data by adopting a redundancy technology; and sending the plurality of copies of completely same data to a receiving end by the main machine and the standby machine. According to the present disclosure, reliability and safety of data transmission are improved.
