摘　　要：本文从Controller Area Network(CAN)总线的特点出发,通过将CAN总线与机载领域应用最成熟的1553B总线进行对比,分析了在航空领域,尤其是在航空机电系统中,局部采用CAN总线的可行性。然后从可靠性和实时性两个方面指出了CAN总线需要在机载适应性上进行的改进。最后结合国外已经发布的CANaerospace和ARINC825协议,指出了在高层协议方面改进的要点,并简要介绍了在国外飞机上CANaero-space和ARINC825的应用实例。At first the characteristics of controller area network（CAN） bus are described,and contrastive analysis with the 1553B bus,which has been used most maturely,is given in this paper.In the aviation domain,especially in the airborne electromechanical system,the partial use of CAN bus is of feasibility.Then it is pointed out that CAN bus should be improved on the reliability and real-time for the on-board requirements.Finally,combining with CANaerospace and ARINC825,some key points for improving on CAN bus application protocol are given,and the CANaerospace and ARINC825 application examples in foreign countries are briefly introduced.
