摘要
以太网的通信不确定性是其应用于实时性要求较高的工业控制系统中的障碍。交换式以太网的出现使这一问题得到了改善。研究了传统以太网和交换式以太网的网络时延问题,根据网络中央节点设备的不同,通过构建工业以太网模型,研究不同负载下网络的性能仿真结果表明了交换式以太网良好的实时性能。
The application of Ethernet in industrial control systems with high specification in requirement of real-time performance is limited because of its indeterminacy in real time communication,This demerit has been overcome due to the appearance of switched Ethernet,This paper studied the ethernet delay of Ethernet and switched Ethernet,When using different central devices,the platform can simulate the real-time performance of Ethernets with these structures under different loads.
