网络化控制系统的可靠性设计与实现

Design and Implementation of Network Control Systems Reliability

为了使网络控制系统能够长期稳定的运行,设计了几种可靠性保障措施。首先,运用DES加解密算法保证了数据在公共网络中传输的安全性;然后设计了PTP deamon精准时钟同步软件,保证了时钟的同步性;最后运用多控制器切换方案,使得当控制器发生障碍时实验能够继续进行。通过搭建网络实验平台验证了方案的可行性。

This paper designs some reliable safeguards to make the network control system operates stably in a long-term.First, the paper uses DES encryption and decryption algorithm to ensure the data transporting security in the public networks.It designs the accurate clock synchronization software which named PTP deamon to ensure the synchronization of the clock. Finally,this paper uses a multi-controller switching scheme to ensure that the experiment can continue when the controller has some obstacles.The feasibility of the program has been verified by building a network experimental platform.
