2) initial data to be measured is gathered by data collector, and discrete is one group of data point；
3) queue that length is n is set, using the data type of flow of " first in first out ", specifically, exactly establishes number
Average according to queue, and to the data in queue, obtain one group of long degree and arrange isometric filter result data row with former data
4) by the fluctuation of algorithm examination data result, if exceeding setting value, queue length, repeat step are increased
3) queue length, is instructed to exceed the value of the setting upper limit, or filter result meets data fluctuations requirement, queue length is to weigh at this time
Measure the quantized data of the quality of data；
5) if queue length reaches the value of the setting upper limit, when data do not meet fluctuation requirement still, then fluctuation is carried out
Exceeded alarm；Otherwise export filtered data and reflect the data fluctuations situation of former data with queue length.
Above-mentioned steps 4) in by the fluctuation specific method of algorithm examination data result be：According toInto
Row judges (S is filter result, and a is single gathered data, and i is filter length, and n is current data)；
4.1) it is 10 to set i, and to SnJudged, if fluctuation exceedes setting value, i is carried out plus 1 operates, will be filtered
Ripple queue is changed into 11；Setting value is true by the way of being estimated to the synthesis of the data normal fluctuation of system under test (SUT) and significant figure numerical value
Fixed, specific formula is that y is setting value in y=1.5*M/N formulas, and M is reading numerical value, and N is normal reading undulating value；
4.2) above-mentioned judgement, i.e. S are carried out againnWhether meet output condition after being set as 11, if data wave momentum meets
Setting value, then pole output data backward；
If 4.3) be still unsatisfactory for imposing a condition, further increase queue length, until queue length exceedes setting value, then
To rear pole output alarm signal, instruction data fluctuations are excessive, are unable to reach design requirement；And discard processing is done to existing data.

The data of instrument are read automatically and instrument controlling, can be applied in a variety of computer data acquisition softwares.
2) elongated queuing data filtering algorithm is used, while good digital filtering effect is obtained, additionally it is possible to quantitative
Measurement data fluctuation situation.
The system has been applied to live ramp rate and has measured in work, and after tested, more original measurement means are compared, measurement essence
Degree and measurement result output readability are significantly better than original means of testing.The system may extend to other electrical parameters for a long time
Occasion is recorded, there is broad prospect of application.
Brief description of the drawings
Fig. 1 is the system block diagram of the present invention；
Fig. 2 is the data processing module processing schematic diagram data of the present invention；
Fig. 3 is the filtering algorithm flow chart of the present invention；
Embodiment
The system can complete the automatic collection of data, its software has specially designed multi-interface data acquisition module,
Support USB, the data-interface such as RS -232, GPIB, has many types of instrument driving energy such as Agilent 34401A, Fluke 8846A
Power, can be automatically performed data acquisition and instrument controlling.And the report of multiple format can be exported, referring to Fig. 1.
Wherein data acquisition module can connect a variety of measure of exterior equipment instruments with multiple interfaces, have stronger versatility,
The block code is one of the system core technology point.
Data processing module, is responsible for analyzing and processing the data acquisition system collected, assessing the parameters such as its ramp rate is
It is no to meet the requirements.The block code is another core technology point of the system.
Data processing module is excludes abnormal data interference, using length variable queue filtering mode, according to data by dry
The serious conditions disturbed, automatically adjust queue length, filter result and queue length are detected, specifically quantify the quality of data.
And filter out useless clutter influence.Data processing module processing mode referring to Fig. 2, the partial code for the system core technology it
One.
Curve S1 is initial data to be measured, can be the electrical parameters such as voltage or electric current, be gathered by data collector, from
Dissipate for one group of data point, the queue that setting length is n, using the data type of flow of " first in first out ", and to the number in queue
According to averaging, obtain one group of long degree and arrange isometric filter result data row with former data.Pass through algorithm examination data result
Fluctuation, if exceeding setting value, increases queue length, repeats the above process, and instructs queue length to exceed the value of the setting upper limit,
Or filter result meets data fluctuations requirement, queue length at this time is to weigh the quantized data of the quality of data, referring to Fig. 3；
When queue length reaches the upper limit, when data do not meet fluctuation requirement still, then the exceeded alarm of fluctuation is carried out.It is no
Then export filtered data and reflect the data fluctuations situation of former data with queue length.
Variable queue filtering algorithm is described in detail below：
(S is filter result, and a is single gathered data, and i is filter length, and n is current data)
It is 10 that i is set during beginning, and to SnJudged, if fluctuation exceedes setting value (such as 5%), i is carried out plus 1 grasps
Make, queue will be filtered and be changed into 11, and carry out above-mentioned judgement again, if data wave momentum meets setting value, pole exports backward
Data, if being still unsatisfactory for imposing a condition, further increase queue length, until queue length exceedes setting value (such as 25),
Then to rear pole output alarm signal, instruction data fluctuations are excessive, are unable to reach design requirement.And existing data are done at discarding
Reason.
