A kind of method temporally managing recording, as shown in Figure 1, it is characterised in that, specific as follows:
When there being recording, the recording task of a length of T0 is when moment t triggers, by event title and the triggering moment of its correspondence
Record in incident file, the total duration T=T0 that records of order, generate a data file simultaneously and combine motion detecting and start record
System.Recording task is divided into long task and short task, and long task is long-time recording of task, short task typically by event-driven,
Only recording comparatively short time or the recording task of the end time of being known a priori by, such as warning video etc., any one task can be touched
Send out recording to start.
In recording process, when when being carved with new recording when ti, the i-th recording task of a length of Ti triggers, do not interrupt working as
Front recording task, only records the event title corresponding to this recording task in this triggering moment and triggers the moment, when showing this
There occurs recording task together quarter, judge simultaneously: if T-(ti-t) > Ti, the most always record duration T constant, if T-(ti-t)≤Ti,
Then total duration T=(the ti-t)+Ti, wherein, i=1 of recording of order, 2 ... n, n are positive integer.So operation increase only total recording
Time, and do not produce new recorded file, it is possible to recording multiple recording task in same data file, it is unnecessary to reduce simultaneously
The taking of memory headroom.
Whenever having recording task to complete, record the task end mark corresponding to this recording task and complete in this moment
Become the moment, show that this recording task terminates；
When all recording tasks complete, if triggering without new recording task, stop recording.
