The calibration mode of 1 girth or the modification model that abrasion roller 1 is carried out with data correction, including setting measurement original position,
The operation such as convert can be carried out to units of measurement.The measuring principle of roller range unit is as follows:
Round capacitive grating code sensor (hypothesis pitch number is N) based on a constant pitch, can be divided into N*512 a circumference
Decile, coordinates the roller of Zhou Changwei C, then the corresponding arc length of each decile that round capacitive grating code sensor is divided into a circumference is
C/ (N*512), i.e. the straight-line displacement Measurement Resolution of this roller range unit.In actual measurement, roller rolls across measuring route, circle
Capacitive grating code sensor can add up decile value and export to single-chip microcomputer, as long as this value is multiplied by resolution by single-chip microcomputer can get
The length surveyed.
This roller range unit passes through the girth of pair roller 1 or diameter row coefficient of relationship is demarcated and substituted the actual fixation of roller
Diameter measures the conventional art of calculating, because conventional measurement techniques measure calculating with the actual fixed diameter of roller, its
The machining accuracy needing pair roller proposes too high requirement and can be only achieved corresponding certainty of measurement.This roller range unit is with roller
Demarcate girth or diameter measures calculating, the machining accuracy being therefore no longer necessary to pair roller proposes too high requirement, passes through
The certainty of measurement to ensure range unit for the method for pair roller girth or diameter demarcation.The demarcation of diameter or girth does not need synchronization
Carry out, user can select oneself convenient demarcation mode as needed, specific operational approach is as follows：
(1) scaling method of roller 1 girth comprises the steps：
S1：Using tape measure, demarcate wheel or other can directly read measurement length instrument choose length be L demarcation
Distance, wherein demarcates and can select as needed apart from L, and distance is more remote, and stated accuracy is higher；
S2：Roller range unit is set to by calibration mode by control button 8；
S3：Roll the demarcation of selection apart from L by handle 6 pushing rolling wheels 1 along tape measure, justified capacitive grating in the process and pass
Sensor 4 is n with roller 1 synchronous axial system output overall pulse number, single-chip microcomputer according to equation below obtain the measurement distance of roller with defeated
Go out the coefficient of relationship k of pulse：
K=L/n；
S4：Carry out demarcation by control button 8 to confirm.
During demarcating, roller 1 circle grid-capacitance sensor 4 while known distance L outputs altogether n arteries and veins
Punching, then the corresponding distance of each pulse is exactly L/n, i.e. coefficient of relationship k.In follow-up measurement, roller 1 is through any distance
L', circle grid-capacitance sensor 4 is corresponding to output altogether n' pulse, then the distance that the distance that roller 1 passes through measures, and passes through
Single-chip microcomputer can be calculated according to equation below：
L'=k*n'.
(2) scaling method of roller 1 diameter comprises the steps：
S1：Roller range unit is set to by diameter calibration mode by control button；
S2：Measure the diameter value of roller with slide calliper rule；
S3：The roller diameter measuring value is inputed to single-chip microcomputer memory storage；
S4：Carry out demarcation by control button to confirm.
During demarcating, the diameter of direct for the size measuring pair roller 1 is demarcated, then circle grid-capacitance sensor
4 each pulse corresponding coefficient of relationship k=π d/ (512*N).The same with above-mentioned measuring principle, single-chip microcomputer is according to equation below meter
Calculation can obtain any measurement distance L'：
L'=k*n'.
Because the precision of slide calliper rule is substantially within 0.05mm, by C=π D, the calibration deviation of girth is about 0.15mm.
Calibration error is analyzed：
Circle grid-capacitance sensor accuracy error is about 3 pulses, because the umber of pulse that circle grid-capacitance sensor often encloses is fixing,
When sensor multiple rotations, the accuracy error of arbitrfary point is still 3 pulses, for improving the stated accuracy of roller girth, we
Select multi-turn calibration.As the calibration of the roller to girth 1m for the 2 pitch capacitor grid transducers, roller rolling 5m, then girth demarcates essence
Degree deviation is about 0.6mm, and the more remote then stated accuracy of rolling distance is higher.Analyze above is the calibrated error of sensor, demarcates
Error also includes the error (5m tape measure error 2.5mm) of gauge, manual operation error etc., artificial for introduce when reducing and demarcating
Error, this roller range unit also carries nominal data debugging functions.Debugging functions mode of operation is as follows：By control button 8
Enter modification model, under modification model, display panel 7 can show the calibration value of roller 1 girth, now by control button 8 by
One reduces the perimeter value that roller 1 is demarcated, with tolling measurement in full-length again after control button 8 storage, until measurement display
Till being approximately equal in size to full-length.Manual operation error can be eliminated by above method, girth calibrated error can control
In 1mm about (sensor error is combined with gauge error).When roller 1 has abrasion, user can also be by above-mentioned rolling
Wheel nominal data debugging functions carry out data correction, to keep the certainty of measurement of roller.The arteries and veins often being enclosed due to circle grid-capacitance sensor
It is fixing for rushing number, is not in cumulative errors during multiple rotations, and above mode of demarcating is to simulate actual tolling measurement mode
Carry out it has been contemplated that the measurement error of manual operation or the inconsistent introducing of pavement conditions, certainty of measurement of 1000m etc. during measurement
Stated accuracy in girth.Roller range finding product 1000m measurement error best on the market at present is 1.5m, uses this roller instead and surveys
Carry out demarcating to come again after the technical scheme of computation and measurement away from filling by pair roller girth, not only reduce wanting of pair roller machining accuracy
Ask, its certainty of measurement is also substantially improved.The diameter of wherein roller is less, then calibrated error can be less.By this measurement device away from
