基于CANopen协议的全电子联锁系统从站设计

CAN总线由于抗干扰能力强、传输距离较远、实时性高、成本低等优点,被广泛应用于工业控制自动化领域。本文将CANopen协议应用于全电子计算机联锁系统,详细介绍了基于CANopen协议的全电子计算机联锁从站的软硬件设计方案,现场实验表明基于CANopen协议的从站设计能很好地满足全电子计算机联锁系统的需求。

Can bus is widely used in the field of industrial control automation because of its strong anti-interference ability,long transmission distance,high real-time performance and low cost.In this paper,CANopen protocol is applied to all electronic computer interlocking system,and the software and hardware design scheme of all electronic computer interlocking slave station based on CANopen protocol is introduced in detail.Field experiments show that the design of slave station based on CANopen protocol can meet the requirements of all electronic computer interlocking system.
