Step S110, during open system daily record dynamic memory function, store the history log information of journal file in the FLASH storer, then extract the history log information of journal file in this FLASH storer, time sequencing according to history log information, the history log information stores one is determined in the fixed length buffer zone of size in the default Installed System Memory, wherein the time is gone up the head of up-to-date history log information stores at this fixed length buffer zone, correspondingly on the time the oldest history log information stores away from the space of the buffer zone of head; Certainly, the afterbody of the oldest this fixed length buffer zone of history log information distance is nearest on the time;
The size of this fixed length buffer zone is much larger than the higher limit of the size of journal file, and this size combines definite according to FALSH storage space size and practical application;
Step S120, under the system journal dynamic memory function unlatching situation, whenever producing new log information, log informations all in the fixed length buffer zone is shifted out the space of the log information size of new generation to the afterbody of fixed length buffer zone, and will be somebody's turn to do the new log information that produces and store in the space that the fixed length buffer zone shifts out; The space of wherein shifting out is positioned at the head of this fixed length buffer zone;
In this step, if store before the log information of this new generation, the log information that remaining space can not complete this new generation of storage in the fixed length buffer zone, then one of the tail position of fixed length buffer zone or more than one log information can be deleted;
The storage mode of this step, guaranteed the log information of each new generation, all be stored in the head of this fixed length buffer zone, guaranteed that the log information in the whole fixed length buffer zone is stored in strict accordance with time sequencing, avoided the problem of generation time confusion when storing daily record information;
Step S130 in each daily record write cycle, checks the log information that whether stores new generation in this fixed length buffer zone, is then to change step S140, otherwise changes step S150;
