The multi-channel space servo control system has a high dependence on the accurate and timely receiving of the position instruction, which requires the communication bus to have the characteristics of high speed, reliability and flexibility.In order to further improve the reliability of position instruction, a non-similar three-redundancy communication system is designed based on Flexray communication. Based on three different hardware platforms, multiple nodes receive the three-way instruction data synchronously within 1ms cycle, and a redundancy management strategy is designed to ensure the correctness of receiving instructions at each execution node.
