Application of Ethernet in Embedded-system Electric Power Remote Terminals for Automatic Meter Reading

Based on the Ethernet transmission principle,this paper is an attempt to apply embedded-system replantation as well as network programme technology,telenet automatic reading meter system based on ARM and TCP/IP is realized.Embedded collection controllers via Ethernet communicate with the reading meter center and accept various control command signals from the reading meter center.Besides,this collection controller has already replanted UC/OS-II real time operating system,which can deal with the multitask,so it enhances system management competence to a large degree.
