| () |
| Abstract: |
| To use Ethernet switch in industrial control field,the failure detection and self-healing mechanism are designed.With priority management the network can transfer data fleetly and reliably.Moreover,double power supply system and some kinds of anti-jamming technology are adopted to meet the requirement of industrial environment. |
| Key words: automatic control,industrial ring-ethernet switch,failure detection,self-healing mechanism,real-time transfer |
