As shown in Figure 1, a kind of fragmentation measurement data uninterrupted sampling memory technology of the present invention, includes the following steps：
Step 100 opens trigger, and trigger can be with detecting real-time external world trigger signal, when trigger detects triggering
When signal, triggering information can be exported in time, notify fragmentation acquisition system.
Fragmentation acquisition system is opened, so that acquisition system is in state to be triggered, acquisition system can real-time detection triggers
State, and react in time to flip-flop states change.
Step 101, system receive first trigger signal in state to be triggered, and system becomes acquisition state, start
Gathered data.
Acquisition time length can be arranged in step 102, system before acquisition, when this complete time span data of system acquisition
Afterwards, it is automatically stopped acquisition.
System can continue through the trigger signal outside trigger detecting in acquisition state.If not having in acquisition time
Detect trigger signal, then total acquisition time is preset acquisition time.
Step 103, when acquisition system detects trigger signal, fragmentation acquisition system is become acquiring shape from state to be collected
State after system starts acquisition, judges that trigger either with or without triggering again in acquisition：
If nothing, step 105 is executed, system starts to cross target signal progress to fragmentation according to pre-set acquisition time length
Record and preservation, after reaching pre-set time span, acquisition system is automatically stopped acquisition；
If so, executing step 104；
Step 104, after triggering starts acquisition to system for the first time, and detect a trigger signal (trigger signal 2), then
It also hold that this trigger signal is effective, and from 2 arrival time of trigger signal, acquisition time reclocking, if without detecting again
To trigger signal, after reaching pre-set time span, acquisition system is automatically stopped acquisition.Trigger signal 2 is adopted before reaching
The data of collection still preserve, and total acquisition time is that the total time that system is triggered to for the first time between acquisition system stopping acquisition is long
Degree.
Step 105, in primary acquisition, if being consecutively detected multiple trigger signals, these trigger signals are considered
Effective trigger signal.When new trigger signal arrives every time, the equal reclocking of acquisition time, until in a complete acquisition time
In length, trigger signal is not detected, then system is automatically stopped acquisition.
It arrives from first trigger signal, stops acquisition to system, all data informations preserve in a collection period
For a data file, the acquisition time length of data is that the total time between being triggered to acquisition system stopping acquisition for the first time is long
Degree.
The data of acquisition are shown according to time spectrum, in the data time axis information acquired in a collection period, mark
