Abstract: A platform named EMECS based on embedded Ethernet control system is implemented. A PC running Fedora 6 (Linux 2.6) works as a central controller. A kit running Linux 2.4 based on Samsung 2410A (ARM920 t core) works as a remote controller and a DC motor (ESCAP 28HSL18-219/204) made by Portescap Company works as a plant. Firstly, system modeling is presented by analyzing the characteristics of Ethernet and the plant, based on a method of delay measurement proposed. Secondly, implementation of the system including program and hardware is described in detail, respectively. And then delay is measured and control results of the system are tested in three cases with different network load as well. The platform is proved to have flexibility to run different control algorithms and extensibility to add nodes. The results of experiment demonstrate the validity of the system.
