摘要
CAN总线是一种主要用于各种过程检测和控制的现场总线网络。由于可靠性高．实时性好,成本较低．近年来已经广泛应用于各种工程控制领域．特别是汽车自动化领域。本文简要介绍了CAN总线的技术特点和工作原理．同时将CAN总线应用于直流电源在线检测,设计了系统结构并介绍了系统的工作过程。
CAN （Controller Area Network） bus is a kind of fieldbus network which is mainly applied to process detection and control. Due to high reliability, real-time and low cost, CAN bus has had a wide application in engineering control in recent years,especially in the field of automobile automation. The technical features and operating principal of CAN bus were presented in this paper briefly. At the same time. we used CAN bus to monitor DC power on-line and design the systematic structure. The operating process of the system was also introduced.
