Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of positional relationship is described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 2-5, operation scale body accuracy judges verifying logic, the calculating of proof rule method, judgement, filing journey
Sequence is realized as follows：
1, scale body accuracy judges verifying logic
More scale body consecutive weighings equipment in, by process flow sequencing appoint take a scale body illustrate verify principle, " appoint
The weighing weight data and " pooled error of one scale body " and " adjacent with any scale body, by the upper scale body of process flow opposite direction "
Range " calculating meets following logic inequality：
" weight data before the variation of any scale body material " subtract " it is adjacent with any scale body, by upper the one of process flow opposite direction
Scale body material variation before weight data " with " and it is adjacent with any scale body, by process flow opposite direction a upper scale body variation material
Weight data " the sum of the difference that obtains, the difference be less than or equal to " the weight section of the corresponding scale body of three above weighing data
The pooled error range of the limits of error ".
Any adjacent scale body two-by-two that more scale body equipment are examined by the above verifying logic, guarantees each scale body of equipment
Work is in accurately and effectively operation interval；To guarantee the accuracy of weight of equipment weighing.
2, " the pooled error ranges of the corresponding weight section limits of error of three weighing datas " described in above-mentioned 1,
" error range " calculates as follows：
" the weight data section limits of error absolute value before any scale body material variation " adds " upper scale body material variation
Preceding weight data section limits of error absolute value " adds " weight data and increase before upper scale body material increasing variation
Twice of data obtained of the sum of section limits of error absolute value where the sum of weight data of material ", i.e. " three weighings
The pooled error range of the corresponding weight section limits of error of data "；
The absolute value of this scale body weight section limits of error of " error range " equal to twice.The expression of the limits of error
For " ± e ", error range is " 2 | e | ".
3, scale body accuracy judges proof rule
Above-mentioned 1 verifying logic inequality is set up, then " any scale body " with " it is adjacent with any scale body, by process flow opposite direction
Scale body Accuracy Verification between upper scale body " passes through.
If verifying logic inequality described in above-mentioned 1 is invalid, " any scale body " with " it is adjacent with any scale body, by work
Scale body Accuracy Verification between the upper scale body of skill process opposite direction " is abnormal, need to point following two situation be further processed：
（1）Scale body between " any scale body " and " adjacent with any scale body, next scale body " along process flow direction is accurate
Property verifying logic situation；
（2）" adjacent with any scale body, by the upper scale body of process flow opposite direction " with " it is adjacent with upper scale body, by technique stream
A upper scale body for journey opposite direction " between weighing data Accuracy Verification " between scale body Accuracy Verification logical situations；
More than if（1）It sets up,（2）It is invalid, then export " adjacent with any scale body, by the upper scale body of process flow opposite direction "
Inaccurate early warning；
More than if（1）It is invalid,（2）It sets up, then exports " any scale body " inaccurate early warning；
More than if（1）,（2）All invalid, then the above scale body weighing is all inaccurate, need to be by proof rule more than（1）,（2）Interior institute
The scale body stated is verified with scale body adjacent thereto.
In Fig. 3, Fig. 6, proof rule is judged according to scale body accuracy, by between each adjacent scale body in more scale bodies
Accuracy Verification verifies abnormal scale body and issues abnormity early warning.
The design requirement of scale body calibrating standard, in scale body weighing data Accuracy Verification method, self-adapting estimation Weighing Area
Between and the section error range, automatically switch across the surveying range corresponding weighting error range of matching.
In Fig. 2, following instance figure does the above rule schematically illustrate so that No. III scale body is " any scale body " as an example；
In more scale body consecutive weighings equipment, there is material support container above scale body, container is mobile by process flow direction, and
Each scale body station can have material to increase in support container.By process flow, No. I to No. VI scale body is in operation
In, each scale body is increasing this component materials（" weight data before the body material increase of this scale "）It is preceding all can be to adjacent upper one
The material total weight of scale body carries out second weighing, which is " weight data before the body material increase of this scale " operational process data
Following table, as shown in Figure 4, Figure 5.
It is above to meet inequality with No. II scale volume data with No. III according to proof rule：
2×| c + b + b'| ≧ | C -（B + B'）|,
If meeting equation, the weighing data Accuracy Verification between No. III and No. II scale body passes through, and otherwise verifying is abnormal, need to be according to
The invalid processing rule of the inequality of 3 dot of second point described above carries out verification processing.
The main feature of this method：
This method passes through multi-component masses and with the one-to-one scale body of component before weighing present component, to the total of previous material
Weight carries out secondary weighing detection, runs testing process to realize self detection between continuous scale body and check and approve, finds in time different
Normal weighing data and abnormal weighing process, guarantee scale body accuracy, material proportion abnormal risk are effectively reduced；
In scale body Accuracy Verification method, the error range in self-adapting estimation weighing section and the section automatically switches across measurement
Section matches corresponding measurement error range, and scale body Accuracy Verification principle complies fully with the design requirement of scale body calibrating standard；
The proof rule of this method design is equally applicable to have continuous more scale bodies as framework using process flow but Weighing control is answered
Miscellaneous technique weighing process, guarantees the weighing weight data accuracy of scale body in error range.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
Protection scope within.
