| Summary: | With the information and intelligence development of rail transit equipment, a safe, reliable, unified and efficient data exchange protocol is needed for vehicle equipment access. This paper proposes a universal information exchange protocol (UXP) made up with a series of basic services. Privilege management mechanism is defined in the UXP and data transmission is dynamically encrypted. The protocol provides efficient data transmission modes, such as break-point continuously transmission, compression transmission, and sliding window transmission and dynamic retransmission mechanism are introduced to improve the transmission efficiency of the protocol. Through various verification such as communication performance comparison between UXP and FTP, UXP communication performance before and after optimization, the results show that the UXP can maintain efficient data transmission in different network environments and guarantee the security of data transmission. |
