摘要
基于工业控制网络系统对冗余功能的需求,结合工程实例从系统的冗余结构、硬件冗余和软件冗余几方面论证了工业控制网络系统冗余的实现方法,尤其对软件冗余的实现及在线检测手段等进行了重点阐述,指出冗余功能是一个工业控制网络系统成功的关键环节,是保证系统稳定、安全、可靠的重要手段。
Based on the requirements of the redundancy function in industrial control network system, the realization method of redundancy was discussed combined with an engineering example from several sides in redundancy construction of system, hardware redundancy, software redundancy,etc. It focused on the method of software redundancy and test means online. It is pointed out the redundancy function is a key link to succeed of control network system in industry. It is importance means to ensure system stable, system safe and system reliable.
