Abstract
The invention discloses an algorithm for eliminating influence of metal exterior decorations such as metal rings or metal letters on tobacco rod moisture density measurement; a density curve of a part of a tobacco rod tip end which is influenced by metal exterior decorations is calculated by mainly using the front and back density symmetry of the tobacco rod determined by the structure characteristics of a flattening disc of a cigarette making and tipping machine, based on a density curve of a lighting end of the tobacco rod which is not influenced by metal exterior decorations, and by combining with the real situations of the tobacco rod tip end. The algorithm of the invention is simple, is easy to realize with respect to operation, and can eliminate influence of metal exterior decorations on tobacco rod density measuring results during tobacco rod moisture density measurement.
Description
Technical field
The present invention relates to the Measurement Algorithm of a kind of cigarette Zhi Shuifen and density, be mainly used in to measure and receive cigarette Zhi Shuifen and the density of metal exterior trims such as becket or metal word under influencing.
Background technology
This algorithm is mainly used in the measurement of cigarette Zhi Shuifen and Density Distribution; The basis of measuring principle is the microwave resonance method; Its groundwork principle is at first to prop up transfer system through cigarette cigarette to be measured is propped up to be sent to microwave cavity; When cigarette props up through microwave electromagnetic field, because the difference of its density and moisture changes the microwave electromagnetic field energy parameter; RF detection system microwave signal that microwave cavity is coupled out is amplified after through little band detection more then, after the AD conversion, data is offered the calculating that CPU carries out cigarette Zhi Shuifen and density; At last result of calculation being shown through man-machine interface supplies survey crew to check.This measuring method can not receive the surface structure that cigarette props up and the influence of color; But because microwave signal is responsive especially to the influence of metal; Therefore receive to have on the cigarette yew paper influence of becket or metal word etc. big especially; The moisture and the density that propped up by the cigarette under the coverings such as becket or metal word are brought difficulty, be unfavorable for in the production run to the control of cigarette quality.
Summary of the invention
In order to overcome the influence that becket or metal word etc. are arranged on the cigarette yew paper; The invention provides a kind of interference that can eliminate becket or metal word etc. for microwave measurement, extrapolate the cigarette Zhi Shuifen and the density of overlay areas such as becket or metal word accurately.
The present invention adopts following technical scheme to achieve these goals:
Eliminate the metal exterior trim cigarette propped up the algorithm that moisture density is measured influence, it is characterized in that may further comprise the steps:
(1) gather cigarette and prop up sample, under the situation of cigarette Zhi Hanyou metal exterior trim, the sample mean densimetric curve that does not receive the metal exterior trim to influence part can be regarded the ideal density curve that cigarette props up as;
(2) at first obtain cigarette and prop up the sample mean densimetric curve that firing end is not influenced by the metal exterior trim by the method for least square curve fitting; Prop up the characteristic of the smooth dish of rolling up and connecting machine according to cigarette; Utilize the Hao Siheerde method of changing of linear least-squares to calculate that smoke is propped up again and connect the mouth end and receive the metal exterior trim to influence the sample mean densimetric curve of part, the cigarette that obtains props up and connects the average density value that the mouth end receives the metal exterior trim to influence part and be designated as f
DesirableProp up with cigarette then and connect the mouth end and receive the metal exterior trim to influence the average density value f of part actual measurement
ActualDeduct the desirable average density value f that extrapolates
Desirable, draw the poor of the two, as empirical value f
Experience, i.e. f
Experience=f
Actual-f
Desirable
(3) measure tested cigarette at last and prop up, cigarette is propped up connect the measured value that the mouth end receives the metal exterior trim to influence part and deduct the empirical value of sampling, draw actual value.
Beneficial effect of the present invention:
Algorithm of the present invention is simple, operates also than is easier to realize, has eliminated cigarette and has propped up in the moisture density measuring process metal exterior trim to the influence of density of tobacco rod measurement result.
