Whether exceed percentage error threshold value δ, until the last one moves to n point, and see if fall out percentage error threshold value δ:
|(Vi+1+Vi+2+....+Vi+5)/5-(V′i+1+V′i+2+......+V′i+5)/5|/[(Vi+1+Vi+2+....+Vi+5)/5]≤
δ %i=0,1 ... n-5, δ are preset percentage error threshold value；
The percentage error for the first time with second of each point is calculated, and sees if fall out percentage error threshold value δ:
|Vi-Vi′|/Vi≤ δ %, i=1,2 ... n, δ are preset percentage error threshold value；
Judgment module is judged to verify unqualified for being just judged to verification qualification when three meets as long as being unsatisfactory for as long as one.
3. the accurate check system according to claim 2 for new-energy automobile charging navigation, it is characterised in that also wrap
Prediction module is included, for predicting the variation tendency of detection when verifying qualified, specifically:
The difference for calculating front and back double sampling value is then denoted as 1 if it is greater than 0；If being equal to 0, it is denoted as 0；If it is less than 0, then
It is denoted as -1, carries out constructed fuction:
It calculatesValue, it is clear that maximum value b=n, minimum value a=-n；
Domain transformation is carried out to basic domain x, is transformed to fuzzy domain, formula are as follows:
M is dispersion in formula.
Here m=3 is taken, fuzzy domain is divided into 7 grades:
{ -3, -2, -1,0,1,2,3 }
Corresponding linguistic variable are as follows:
{ negative big, to bear, bear small, zero, just small, center is honest }
If testing result is 3 always, i.e., testing result is " honest " always, although then explanation result does not transfinite, is detected
Value is greatly to the edge to transfinite；If testing result is -3 always, i.e., testing result is " negative big " always, although then explanation knot
Fruit is not transfinited, but detected value is small to the edge to transfinite；If testing result be always " negative in ", " bearing small ", " zero ",
One in " just small ", " center ", then illustrate that testing result does not transfinite, and detected value deviation is also little；Although if inspection
Surveying result does not transfinite, but jump is larger, then illustrates that testing result is unstable.
