基于CAN总线的铝电解计算机控制系统

CAN-based Bus for the Computer Control System of Aluminum Reduction Cells YUAN Ding

介绍了CAN总线在铝电解槽控制系统中的应用。叙述了基于CAN总线的系统结构、组成及特点。根据铝电解生产的特点详细讨论了传输的数据约定协议 ,给出了CAN总线通信接口软件设计方案。用CAN总线解决了过去BITBUS控制系统中存在的问题。

The application of CAN bus in the control system of aluminum reduction cells,its systematic structure,composition and characteristics are described in this paper.To be more specific,the detailed data transfer agreement and the interface software plan for CAN bus communication are discussed on the basis of aluminum reduction requirements.Due to its adoption,the problems in BITBUS system have been successfully overcome.
