Power distribution DTU multi-interval comprehensive wave recording management system and method

The invention provides a power distribution DTU multi-interval comprehensive wave recording management system. The method comprises the following steps: firstly, carrying out thread division design through channel data recording and waveform file storage according to different real-time requirements, and setting intermediate waveform data cache write-disk queues according to intervals to realize fault recording execution among multiple intervals and decoupling of intermediate recording data, and ensuring that normal operation of other functional modules on equipment is not influenced; and secondly, realizing mutual decoupling of storage and retrieval of the multi-interval historical fault information through a sub-queue multi-stage management technology of the multi-interval historical waveform data and the fault information report data, and finally realizing the purpose of completely independently managing the multi-interval fault information of the power distribution DTU. The invention also provides a corre
