Title: Design and implementation of dual-redundant communication mechanism based on CAN bus under DSP
Abstract: To meet the high reliable demand of the communication among subsystems of the main-controlling equipment,a dualredundant communication mechanism based on CAN bus under DSP was proposed.Then,the dual-redundant communication system of the main-controlling computer combined with the practical application of the system of the main-controlling equipment was designed and implemented.After that,the designing and implementing process of the software and hardware of the mechanism was expounded in details,the key and difficult points in realizing the design of the dual-redundant protocol,the frame structure,the use of timer,and the interrupt communication were analyzed particularly.Finally,the reliability of the dual-redundant system of the main-controlling computer was analyzed,and the testing experiment was done.The analyzed results and experimental results show that the mechanism can improve the reliability of the communication between systems obviously.
