- Abstract
In order to solve the problem of unsafe internal communication bus of CTCS-3 safety computer platform, this paper designs a kind of bus that can meet the security network requirements in EN 50159. The bus has hardware structure of dual two out of two to group and package application layer data, add CRC encoding and validation to application layer data, and detect a number of communication functions and security assurance functions such as the full-duplex data communication between the master and the slave of point-to-point link connection status. The bus can solve the problem of internal security communication of onboard platform and have great significance to the research of safety computer onboard platform.
