基于现场总线的三模冗余计算机联锁控制系统的研究

Study of TMR Computer based Interlocking System Based on Field Bus

控制器局域网是主要用于各种过程检测和控制的一种现场总线网络，它具有优先权和仲裁功能．多个单片机可通过ＣＡＮ控制器连接到ＣＡＮ总线上，形成多主机的局部控制网．本文主要介绍ＣＡＮ控制器８２Ｃ２００在三模冗余计算机联锁系统中的应用．

CAN is the acronym of Controller Area Net, which is said as the Controller LAN. CAN is a kind of field bus network which is mainly used in the process detection and control. CAN has bus access priority and arbitration function. Several one chip micro computers can be connected with CAN bus through CAN controller to configure a multi master Area Control Net. In this paper, we mainly introduce the application of CAN controller 82C200 in Computer based interlocking system.
