Abstract

The invention discloses a cross-network clock synchronization communication device and method between different networks. The device comprises a gateway node, wherein the gateway node comprises a master network protocol control unit, the master network protocol control unit, a cross-network clock synchronization unit and a sub-network protocol control unit are in one-way communication connection; the master network protocol control unit, a cross-network communication scheduling unit and the sub-network protocol control unit are in two-way communication connection; the master network protocol control unit and a master network are in two-way communication connection; and the sub-network protocol control unit and a sub-network are in two-way communication connection. The gateway nodes of different networks are coupled through design, the cross-network clock synchronization and cross-network time triggered communication between the different networks are realized, specifically, according to the communication device, the gateway nodes of TTE and FlexRay can be coupled, and the cross-network clock synchronization and cross-network time triggered communication between the TTE and FlexRay can be realized.

Description

Technical field [0001] The present invention belongs to the technical field of communication between different networks, and relates to cross-network clock synchronization technology for different types of time-triggered networks; specifically relates to a cross-network clock synchronization communication device between different networks, and also relates to a cross-network clock synchronization between different networks. Network clock synchronization communication method. Background technique [0002] Both TTE and FlexRay have sub-microsecond clock synchronization and time-triggered communication capabilities. TTE and FlexRay both use distributed clock synchronization in the network clock synchronization mechanism. For TTE network clock synchronization, please refer to the SAE AS6802 protocol. For FlexRay network clock synchronization, refer to the FlexRay Communication System Protocol Specification Version 2.1 protocol. TTE and FlexRay network node cycle The sexual interacti...
