一种高效的双通道冗余电子控制器通道间信息交互方案研究
Research on an efficient information exchange scheme between dual channel redundant controllers
摘要
Abstract
For the hot backup working mode of dual-channel redundant electronic controllers,a design scheme of a multi-functional chan-nel management module based on CPLD is proposed to achieve efficient data exchange and synchronization between primary and backup channels.Serial Peripheral Interface(SPI)is used for communication and synchronization,with the management module serving as the SPI communication host to implement data broadcasting to both primary and backup channels and direct bridging between them,while also possessing the capability to monitor communication data.Based on simulation verification,the serial communication management functions normally,with the delay caused by timing logic in SPI bridging and broadcasting being 30 ns,indicating good system real-time performance.Tests on the SPI data transmission function of the designed dual-channel redundant electronic controller show that data in-tegrity is good in both serial loopback and SPI data exchange tests,meeting the design requirements.关键词
