摘要
随着海洋控制技术的不断发展,舰船电子武器装备的不断增多,舰船通信系统逐渐趋于复杂,需采用更为精细的通信机制以降低系统的复杂性。CAN总线是一种支持双向串行多节点通信的现场总线,对舰船复杂的通信网络具有很好的适用性。然而由于CAN总线的带宽有限、通信过程中难免受到干扰等问题的存在,对通信的可靠性产生影响。论文对舰船CAN总线通信可靠性进行研究,对基于CAN总线的可靠性定义、可靠性影响因素进行论述,并从软硬件角度提出了提高CAN通信可靠性的方法,对舰船CAN总线设计、提高通信的可靠性具有重要意义。
With the continuous development of ocean control technology and the increasing number of electronic warfare equipment,the ship communication system is becoming more and more complex,and more sophisticated communication mecha⁃nism is needed to reduce the complexity of the system.CAN bus is a kind of field bus supporting bidirectional serial multi-node com⁃munication,which has good applicability to complex communication network of warships.However,due to the limited bandwidth of CAN bus and the unavoidable interference in the communication process,the reliability of communication is affected.In this paper,the reliability of ship CAN bus communication is studied.The definition of reliability based on CAN bus and the influencing factors of reliability are discussed.The method of improving the reliability of CAN communication is proposed from the point of view of soft⁃ware and hardware.It is of great significance to the design of ship CAN bus and the improvement of the reliability of communication.
