In the case of multiple combinations in breath, purposes information, product type information and steel information, the attribute information of highest priority is obtained
Corresponding preset rules, wherein the sequence of the priority of attribute information from high to low is customized user information, purposes information, produces
Product type information and steel information.
Specifically, in the present embodiment, attribute information may include customized user information, purposes information, product type information
And steel information, the priority for needing to carry out different attribute information divide.In the present embodiment, it is set from high to low according to priority
It is set to customized user information, purposes information, product type information and steel information totally four ranks, in no special instruction
Be defaulted as only to product type information design preset rules, i.e., for hot-rolled product, acid-washed product, continuous annealing product, galvanizing production,
Tin-plated product etc. carries out different preset rules settings.
Such as: the rule of the corresponding severity level of different customized user informations is different, such as: being linearly mingled with this and lacks
It falls into, corresponding 1 grade of customized user A is mingled with decision condition linearly for L≤20mm or B≤2mm, and L indicates defect length (mm), B table
Show defect width (mm).Corresponding 1 grade of customized user B is mingled with decision condition linearly for L≤18mm or B≤3mm.So different
The corresponding preset rules of customized user information it is different.Similarly, the different corresponding preset rules of purposes information are also different, different
The corresponding preset rules of product type information it is also different, the corresponding preset rules of different steel information are also different.These rule
It then can be set according to actual needs, the application is with no restrictions herein.
If it include a variety of in the attribute information of coil of strip to be detected, such as: it include customized user information and steel information,
It, can be according to the corresponding default rule of customized user information since the priority of customized user information is higher than the priority of steel information
The severity for then carrying out defect is graded.
In turn, when grading to surface defect having detected that, having determined that title, defect severity level, than
Such as: set 5 grades altogether, be 1,2,3,4,5 grade respectively, severity from light to heavy, i.e., 1 grade be mired, 2 grades be it is slight, 3 grades be
Moderate, 4 grades be severe, 5 grades be serious.Assuming that L indicates defect length (mm) for being linearly mingled with this defect, B indicates to lack
It falls into width (mm), in the preset rules for being hot-rolled product with product type, 1 grade is defined as L≤20mm or B≤2mm, and 2 grades fixed
Justice is 20 < L≤100mm or 2 < B≤3mm, and 3 grades are defined as 100 < L≤200mm or 3 < B≤4mm, 4 grades be defined as 200 < L≤
300mm or 4<B≤5mm, 5 grades are defined as L>300mm or B>5mm.In turn, in this way, each list can be determined
Grade defect existing for member, such as: the 1st unit is linearly mingled with there are 1 grade, and 2 grades are linearly mingled with.There are 1 grade of lines for 2nd unit
Property is mingled with, and 3 grades are linearly mingled with.3rd unit is linearly mingled with there are 2 grades, and 4 grades are linearly mingled with etc..
In turn, after determining grade defect existing for each unit, step S104: all units based on acquisition is executed
Existing grade defect determines the corresponding coil of strip grade of each grade defect.The step can be accomplished in that
For each grade defect, the number based on the grade defect that each unit occurs determines that each unit is directed to
The evaluation grade of the grade defect and the corresponding weight of the evaluation grade；
It is directed to the evaluation grade and the corresponding weight of the evaluation grade of each grade defect based on each unit, determines every
The corresponding coil of strip grade of a grade defect.
Specifically, in the present embodiment, the corresponding weighted value of different level of evaluation is preset, weight setting method is intended to
Influence of the major defect to product quality intuitively is embodied, is the algorithm basis of quantitatively evaluating, and it is more serious to embody defect

It is fixed, here, the application is with no restrictions.
In turn, when calculating the corresponding coil of strip grade of different brackets defect, it is thus necessary to determine that each unit is directed to the grade defect
Evaluation grade.Following table shows the number that different grade surface defects occurs in a unit, and different numbers are corresponding
Each unit is directed to the evaluation grade of the grade defect.The unit evaluation of matrix form is established according to defect title and evaluation grade
Table, specific example such as the following table 1:
Table 1
It should be noted that number described in table 1 represents defect number in a unit, for 3 iron scale of grade,
Occurs 1 to 5 in one unit, the evaluation grade for showing that the unit is directed to 3 iron scale of grade is 1, is shown if >=6
The unit is 2 for the evaluation grade of 3 iron scale of grade.And major defect this for hole, as long as occurring one, table
The bright unit is 5 for the evaluation grade of hole.
In turn, the evaluation grade and the corresponding weight of the evaluation grade of each grade defect are directed to based on each unit,
Using average weighted mode, the corresponding coil of strip grade of each grade defect is determined.Specifically, being directed to A grade defect B, unit 1
Evaluation grade to A grade defect B is C1, and the corresponding weight of evaluation grade C1 is D1.Assessment etc. of the unit 2 to A grade defect B
Grade is C2, and the corresponding weight of evaluation grade C2 is D2.And so on, unit N is CN, assessment to the evaluation grade of A grade defect B
The corresponding weight of grade CN is DN, then the coil of strip grade of A grade defect B=(C1 × D1+C2 × D2+ ...+CN × DN)/(D1+
D2+……+DN).If calculated coil of strip grade includes decimal, can Figure correction according to national standards " rounding up "
Rule arrives integer value into house.
It includes 10 units that coil of strip to be detected is illustrated in the following table 2, each unit to the evaluation grade of each grade defect,
The corresponding coil of strip grade (being rounded to integer value) of each grade defect obtained with this.
Table 2
Further, in the present embodiment, it for each grade defect, exports corresponding with the coil of strip grade of the grade defect
