If so , is it possible to make it a redundancy double ( dual ) ring network to ensure the high reliability of the automation system 如果能,是否可以构成冗余的双环形网络来保证自动化系统的可靠性?
In this paper the communication and collecting data and the design of software and hardware are elaborated . in the construction of network , this system adopt both direction circle redundancy network . making use of its advantage can transfer data by both direction , so without reference to anyone node has error that can not affect natural working 在网络拓扑结构上本系统采用双向环形冗余网络(双环形以太网) ,利用双向环形冗余网的特点可以双向传输数据,因此不论任何一个节点出现问题都不会影响正常的工作状态,假设在某一方向出现了问题可以通过另一方向传输数据,这样就更增加系统的实时性、稳定性。
