Abstract:

At present,most of the hardware platforms in distribution network are of low main frequency and small memory, and are mainly used on single loop device in feeder terminal units(FTU).As for the multiloop scenario in data transmission unit (DTU), only the fundamental functions can be implemented.Realizing multiloop sampling and recording requires large data file storage and high realtime application functions,which has high requirements for the main frequency and memory.Aiming at this situation,a method based on Freescale MK64 platform and external SDRAM is designed.It can be used in DTU multiloop recording storage scheme to support fast trigger recording and correct file storage under 4 fault sequences.Feasibility of the scheme has been verified by sampling data and waveform files of the actual device.
