Redundancy Technology of CAN-Bus Network
This article classified the CAN bus in accordance with the bus number, and detailedly studied the development status and problems both in single bus redundant system and dual-bus redundant system, moreover analyzed three main issues exist in redundant technique applications with high reliability which are the rapidity and accuracy of network fault detection, and how to improve network efficiency in data transmission and reduce the probability of task conflict, as well as flexible and efficient in design of communication protocol. Finally, the foreground applications of CAN bus in high-reliability field like Aero-Space is summarized.
