CCD image sensor 1-4 in the sensing unit 1 is a kind of capacitive coupling N-type semiconductor N image device, it is that unit cell arrangement by some forms, the physical dimension of each unit (being also referred to as photosensitive unit or pixel) all is identical definite value, and it can store the signal charge that is produced by light or electric excitation.When it is applied the pulse of specific time sequence, the signal charge of its storage just can be done directional transmissions and realize self-scanning in CCD, therefore, with optical means measurand is imaged in the photosensitive unit of CCD, the CCD image sensor just converts the optical information in the photosensitive unit and the proportional quantity of electric charge of light intensity to, time clock with certain frequency drives CCD, can obtain the vision signal of measurand at the output terminal of CCD, in the vision signal size of each discrete voltage corresponding the power of this photosensitive first institute receiving light power, and the order of the photosensitive first position of sequential correspondence CCD of signal output.The utility model utilizes this principle of CCD to carry out the measurement of yarn physical dimension.
The CCD image sensor has two kinds of linear array and face arrays usually, and the utility model adopts linear array CCD image sensor, and yarn is vertical with the orientation of the photosensitive unit of CCD, and is parallel with the sensitive surface of CCD image sensor.Fig. 2 has described the situation of certain yarn imaging on CCD in a flash, optical devices are imaged on yarn on the photosurface of CCD, the picture of the normal yarn of thickness accounts for b on CCD, c, d, e, f, the photosensitive unit of g, the filoplume on right side accounts for h on CCD, I, j, k, l, m, the photosensitive unit of n, this moment is at the corresponding b of output terminal of CCD, c, d, e, f, the voltage that the photosensitive unit of g is exported, corresponding h, I, j, k, l, m, between the voltage three that photosensitive unit exported that the voltage that the photosensitive unit of n is exported and other are not blocked tangible difference is arranged, just can judge several photosensitive units according to the voltage of CCD output is blocked by yarn, there are several photosensitive units to be blocked by filoplume, because the separate unit of CCD device is that the physical dimension of photosensitive unit is a definite value, therefore, can calculate the length of the diameter and the filoplume of yarn.
Because yarn is moving, when a certain, to be carved with the yarn of slubbing or to have the yarn of details to be imaged on the CCD, the photosensitive unit that is blocked just increases or reduces, and what that increase or reduce just can calculate the size of slubbing or details according to.
Selecting the main basis of CCD is test speed and measuring accuracy, present embodiment adopts the TCD1501 line array CCD, its photosensitive unit is 5000, photosensitive first size is 7 μ m * 7 μ m, and centre distance is 7 μ m, works under the TTL pulse, power supply is 12V, clock is two-phase (5V), and inside comprises sampling hold circuit, adopts 22 pin DIP encapsulation.
Because the spectral response range of CCD device is 0.4-1.5 μ m, the light source of imaging system must satisfy this condition, and the light source 1-1 of present embodiment adopts an iodine-tungsten lamp, and light modulation power supply 1-2 adopts the constant-current source that 0～5A is adjustable, and light intensity is adjustable.Optical devices 1-3 adopts a common amplifying lens, and its focal length is 168mm, and iodine-tungsten lamp is placed on the focus of lens, and light source is through being parallel light emergence behind the lens, and yarn is placed on the centre of lens and CCD, and the shade of yarn is imaged on the CCD surface.Just export the vision signal that is comprising yarn diameter, thickness joint, filoplume information at the output terminal of CCD.

Two groups of numbers of represent pulse width that computing machine takes out, one group of correspondence the picture size size that yarn diameter contains the thickness joint, another group correspondence the picture size size of Yarn filoplume.These two groups of numbers multiply by the size that pulse equivalency obtains picture respectively, and the enlargement ratio that multiply by optical devices more just obtains the physical size of measurand, that is: yarn diameter contains the size of thickness joint and the length dimension of Yarn filoplume.But these two groups of results that number only is the CCD single pass, it also is the size of a photosensitive first length (being 7 μ m in the present embodiment) on the length of yarn direction, because yarn is to move with certain speed, CCD scanning is also constantly carried out with certain frequency, therefore, computing machine just can obtain various such arrays, use these arrays, computing machine on the one hand simulates with pixel (photosensitive unit) on screen to be horizontal ordinate, to be of a size of two dynamic images of ordinate with yarn diameter size and Yarn filoplume.On the other hand, obtain the test index of various needs by calculating, as mean diameter, CV% value, slubbing number (according to the percentage statistic of classification thicker), details number (according to the percentage statistic of classification thinner) filoplume number (according to the statistic of classification of filoplume length) than mean diameter than mean diameter, with the form printout of test report, also can use form deposits such as test report, text for future reference again.Present embodiment calculates following index: mean diameter, mean square deviation, CV% value, slubbing :+25%+45%+50%+70%+100%, details :-25%-35%-45%-50%-60%, cotton knot :+100%+150%+250%+300%+400%, filoplume number (every 1mm divides one grade among the 1-25mm) is drawn the filoplume distribution curve.
The photosensitive elemental size of CCD directly affects testing precision, and photosensitive elemental size is more little, and measuring accuracy is high more, and the sweep velocity of CCD directly affects testing efficiency, and the fast more testing efficiency of sweep velocity is high more, and correspondingly the cost of test macro is also high more.The travelling speed of yarn need cooperate with the sweep velocity of CCD,
The utility model has designed yarn speed and has regulated display 3, as shown in Figure 5, initiatively roller 2-8 connects with the rotating shaft of motor 2-9, motor 2-9 is connected with speed regulator 8, photoelectric encoder 6 is installed in the rotating shaft of motor 2-9, the pulse of photoelectric encoder 6 output is connected to velocity survey display 7, and velocity survey display 7 has the RS232 interface that can communicate with computing machine.Present embodiment adopts small-sized variable-frequence governor 8 to regulate yarn speed, what the lower-cost photoelectric tube of photoelectric encoder 6 employings was joined forms in code-disc, velocity survey display 7 becomes linear velocity with the pulses switch of photoelectric encoder output, show with the rice per minute, simultaneously, send computing machine to by the RS232 interface, so that the length of COMPUTER CALCULATION test yarn and every index.Motor 2-9 of the present utility model also can adopt stepping motor, carry out speed by computing machine output driving pulse and regulate, but this method need take executive program, often influences the execution of main test procedure.
The test of adopting the CCD image sensor to carry out the yarn physical index is a kind of direct measuring method, because the pixel very little (normally micron order) of CCD, measurement can be very accurate, yarn trunk and filoplume are easy to distinguish, and undesired signal also differentiates and separates that this is that capacitance measurement commonly used at present can't be accomplished than being easier to.The utility model has been realized once walking the purpose that yarn is tested multiple yarn index on an instrument, therefore, has reduced total testing cost.
