| Abstract: |
| There are many elements of MICAPS historical data,which take up a large space and are not easy to keep for a long time. This paper introduces an idea and method of cutting appropriate range area, deleting uncommon elements and rewriting data storage format to compress data files and save important data. The application in the last two years shows that this method is stable, practical and easy to operate, which can solve the problem of massive historical data backup in basic stations. |
