The Research Of Fault Recorder Based On Embedded System

Fault recorder is a kind of device recording and analysis power systems faults, it has experienced photoelectric fault recorder and computerized fault recorder development stage. Computerized fault recorder plays an important role in modern power systems on fault disposal and power restoration. However, computerized fault recorder has exposed some problems due to its split structure.This paper focuses on using UML (Unified Modeling Language) to establish the model of fault recorder device and how to realize the UML model on embedded system. Firstly, using Case diagram, Sequence diagram, Class diagram and Activity diagram to finish the static modeling and dynamic modeling, then propose an embedded, integrative power systems fault recorder scheme based on the UML model, lastly, established the embedded system platform based on ARM (advanced RISC machines) microprocessor, 10M/100M Ethernet and embedded uClinux operation system, using diagram and programs to show how to carried out this fault recorder model on the embedded platform. This new kind of fault recorder's main functions are data collection, fault judging, fault information storage and network communication. The embedded system solution for fault recorder can also be used to realize other informational smart network devices.
