摘要
控制器局域网(CAN)是一种主要用于各种过程检测和控制的现场总线网络。CAN总线采用双线串行通讯方式,具有很强的检错和抗干扰能力,最高通讯速率可达1Mbit/s,最大通讯距离为5000m,CAN还具有优先权和仲裁功能。本文主要介绍CAN总线的技术特点、工作原理及应用。
CAN is the acronym of Controller Area Network, which is called Controller LAN. CAN is a kind of field-bus network mainly used in process detection and control. CAN bus has some special properties, such as serial communication by dual line, powerful capability of error detection and anti-interferring, 1 Mbit/s highest communication speed and 5000 m longest communication distance. CAN also has functions of bus access priority and arbitration. This paper mainly presents its technical features, working principle and applications.
