基于CAN总线的机载机电综合管理平台设计

摘要

鉴于CAN总线的诸多优点,设计了一种基于CAN总线的机载机电综合管理半物理仿真平台,详细说明了该仿真平台中的各个组成部分和功能,利用该仿真平台可以对机电系统进行数字仿真和半物理仿真,并引入远程接口单元(RIU)和CAN热冗余结构来保证系统的可靠性和容错性,将优先级和时间片轮转调度算法结合,实现了对系统的综合管理.%In view of many advantages of CAN, a simulation platform for aircraft utility management system based on CAN is designed and the description of the various components and their functions are given in details. It can fulfill digital and semi-physical simulation for the system. Simultaneously, the platform introduces remote interface unit (RIU) and thermal redundancy of CAN to ensure the reliability and fault tolerance of the system. This management system combines the priority algorithm and rotation scheduling algorithm for time slice.
