The data recovery system and data reconstruction method of FFR host

The present invention provides a kind of data recovery systems of FFR host characterized by comprising mark module is used to be arranged shutdown label；Non-volatile memory module is used at least be stored with shutdown label；Monitoring modular, is used to obtain the real time data of patient, and is written in non-volatile memory module；Correction verification module is used to read shutdown label, and judges that shutdown marks whether as abnormal off-mode；And recovery module, whether real time data is extracted from memory module based on shutdown marker for judgment, when shutdown is labeled as abnormal off-mode, extracts real time data from non-volatile memory module.In accordance with the invention it is possible to the case where preventing loss of data caused by abnormal shutdown caused by burst power-off appearance.
