Telecontrol Technique Of Electric Systems Based On Embedded IP

Telecontrol technique of electric systems has developed decades from 1940s to now, appeared several generations telecontrol system. It has become the Essential important guarantee of economical operation of power systems. But the traditional telecontrol system, which adopted the CDT or Polling protocol has a lot of drawbacks. This paper proposed a telecontrol technique of electric systems based on the embedded IP technique, aimed at the traditional telecontrol system's drawbacks.In this paper, it has made a study of the several issues of the telecontrol technique based on the embedded IP technique. First, it introduced the develop of the telecontrol technique of electric systems. Second, it expatiated the telecontrol protocol of the embedded IP technique. And then studied the network access of the remote terminal equipment. Finally, analyzed the structure of the main station and the system's security. In them, I emphatically studied the telecontrol protocol and the network access. Include the study of the structure of IEC60870-5-104 protocol, the mechanism of prevention to the message's losing and conveying repeatedly, porting of the embedded operation system-uC/OS-II and TCP/IP protocol stack-LWIP, and the circuit design of the network access. Then, I had a experiment on the ARM board-S3C4510B.
