Description
Technical field
The present invention relates to a kind of digital display calliper automated detection system.
Background technology
21 century is the information age, and the fusion of infotech and manufacturing technology is the Main way of 21 century Manufacturing Technology Development.The fast development of modern science and technology is that the progress of detection technique and development create condition, meanwhile, constantly proposes the requirement of more Gao Gengxin to detection technique.Current most domestic manufacturer is all the method-metal gauge block sectional detecting method adopting manual detection, and traditional manual detection method working strength is large, efficiency is low, there is larger personal error, so current manual detection method more and more can not meet the requirement of modern production, digital display calliper automated detection system is needed to replace manual detection method, not only can carry out verification according to existing national metrological verification regulations to slide calliper rule to measure, can also measure the arbitrary dimension position of slide calliper rule.While employing microcomputer carries out error correction automatically, realize numerical monitor, make surveying work intuitive and convenient more.
Summary of the invention
The object of the invention is to reduce larger human error, enhance productivity, there is provided the data feedback of digital display calliper check point on computing machine, contrast with the standard value of check point, accurately can detect a kind of digital display calliper automated detection system of each check point deviation.Should solve existing for existing manual detection based on the digital display calliper automated detection system of high precision Grating Detecting System: the defects such as working strength is large, efficiency is low, error is larger.
For achieving the above object, a kind of digital display calliper automated detection system of the present invention comprises computing machine, digital display calliper measuring system, Grating Detecting System, driving governor, computing machine is connected with Grating Detecting System by RS232, is connected respectively with digital display calliper detection system, driving governor by USB.
Described driving governor comprises control panel and stepper motor, the direction of the displacement commands control step motor that control panel receiving computer sends and displacement.
Described computing machine has manual detection and automatically detects two patterns.
Described manual detection pattern refers to the shift length inputting check point artificially, detects one by one all check points.
The testing process of described autosensing mode is as follows: 1. digital display calliper chi head closes, and is loaded on instrument, and computing machine reads grating currency, as absolute initial point ABS0; 2. input needs the frequency n of detection on computers, and the displacement command sending first check point positions; 3. control panel receive displacement command reply receives successfully give computing machine, and send Pulse Width Control stepper motor move; 4., after movement completes, control panel sends and has moved order to computing machine; 5., after computing machine receives and moved order, reading currency and ABS0 subtract each other delivery, calculate actual displacement S0; 6. the verification carrying out next check point is prepared, until all check points have detected; 7. repeatedly detect n time, obtain n group displacement data, carry out mean filter, replace measured value with mean value, finally adopt least square method to carry out linear fit to this cell mean, obtain parameters input in slide calliper rule.
Described mean value is that n group data acquisition mean filter method calculates, and n data of each point is calculated mean value to replace measured value, finally obtains a cell mean.
The invention has the beneficial effects as follows: the speed that the invention solves Traditional Man detection is slow, and the difficult problem that human error is larger, especially introduces Grating Detecting System, substantially increase accuracy in detection.Therefore there is accuracy of detection high, the advantages such as speed is fast, simple to operation.The detection demand of digital display calliper industry that what the advantage that the present invention has was very large meet, has very large development potentiality and application prospect.

Embodiment
Fig. 1 is the structural representation of digital display calliper automated detection system of the present invention.The present invention is a kind of digital display calliper automated detection system, mainly comprise computing machine, digital display calliper measuring system, Grating Detecting System, driving governor, computing machine is connected with Grating Detecting System by RS232, digital display calliper measuring system reserves communication expansion interface, be connected with computing machine, meanwhile, computing machine is responsible for carrying out Communication Control to driving governor.
The human interface of computing machine has two kinds of patterns: manual detection and automatically detection.Manual detection needs, by the input one by one of the displacement of check point, to detect under this detecting pattern to arbitrfary point.That check point set in digital display calliper measuring system is detected one by one under autosensing mode.
The testing process of autosensing mode is as follows: 1. digital display calliper chi head closes, and is loaded on instrument, and computing machine reads grating currency, as absolute initial point ABS0; 2. input needs the frequency n of detection on computers, and the displacement command sending first check point positions; 3. control panel receive displacement command reply receives successfully give computing machine, and send Pulse Width Control stepper motor move; 4., after movement completes, control panel sends and has moved order to computing machine; 5., after computing machine receives and moved order, wait for that grating is stablized, reading currency and ABS0 make delivery, calculate actual displacement S0; 6. the verification carrying out next check point is prepared; 7. repeatedly detect n time, obtain n group displacement data, carry out mean filter, replace measured value with mean value, finally adopt least square method to carry out linear fit to this cell mean, obtain parameters input in slide calliper rule.
Mean value is that n group data acquisition mean filter method calculates.Making n group measured value form n array is X
1, X
2, X
3x
n, the value of correspondence each in these arrays is averaged, that is:
Obtain a cell mean X.What the standard value Y that this group numerical value X and grating export is adopted least square carries out linear fit, and can obtain fit equation: Y=aX+b, in formula, a, b represent Monomial coefficient and constant term respectively, be input in slide calliper rule, complete detection by a obtained, b.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
