摘要
交换技术和全双工技术在以太网中的应用使得工业以太网的通信实时性和确定性大大提高 ,底层智能节点是基于Rabbit 2 0 0 0的嵌入式系统 ,它具有实时性好和可靠性高等优点 ,基于交换式以太网的嵌入式测控系统将两者进行了有机的结合。首先介绍了控制系统的结构 ,然后分析了通信系统的流程 。
Now the performance of industrial Ethernet has been improved dramatically by introducing switching technology and full duplex technology.The intelligent nodes of embedded system, based on the Rabbit 2000,have an excellent performance of real time and high reliable characteristics.The system discussed integrate the two technologies organically.The components of control system are introduced in brief,and the flowchart of communication system is analyzed.The simulation result proves that the system is feasible and reliable.
