Problems solved by technology

The disadvantage of this system is that it only considers the transmission of user data and does not consider the transmission of management data, so it cannot be used in the network scenario of time-triggered Ethernet; it does not consider the redundant transmission of data, and cannot guarantee the reliability of network data transmission sex
The disadvantage of this method is that the AS SAE6802 protocol used to achieve time synchronization is complex and less reliable in hardware, and the stability and accuracy of time synchronization are also lower.

Abstract

The invention discloses a device and method for implementing a time-triggered Ethernet end system. Based on the Ethernet technology, the time-triggered Ethernet end system capable of transmitting time-triggered data and event-triggered data is implemented by increasing the functions of time synchronization and time trigger. A special protocol processing module of the device can process managementdata more conveniently; and a transmission processing module of the device can guarantee the reliability and the robustness of a network in the data transmission process. By adopting a precise clock synchronization protocol IEEE 1588, the method provided by the invention reduces the difficulty of implementing time synchronization on hardware, and has higher time synchronization stability and synchronization accuracy.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a device and a method for realizing a time-triggered Ethernet end system in the technical field of Ethernet. The present invention is based on the Ethernet technology and introduces the time synchronization technology and the time trigger technology to realize an end system device and method capable of processing time trigger data and event trigger data with a time synchronization function. Background technique [0002] The time-triggered Ethernet end system is based on time-triggered Ethernet. It is based on the Ethernet communication network. The idea is to add clock synchronization technology and time-triggered technology to standard Ethernet to make Ethernet a time-deterministic network. Make the end system meet the needs of real-time and non-real-time applications at the same time. At the same time, the precise clock synchronization IEEE 1588 protocol has high-p...
