By the prompt development of textile industry, the design of the equipment of textile industry is developing towards high precision, multifunction and low cost. ISM is one of the key equipment in textile industry. It is composed of motor servo system and the traditional sewing machine, so it has some additional functions besides all of the functions provided by traditional sewing machine, for which the efficiency of product line can be improved greatly by its high automation, as well as the product quality. The precision of ISM is mainly determined by the control precision of the motor servo system. Therefore, it is essential of the research on the motor servo system to developing an ISM system. Presently, classic PID control theory is mainly adopted in the research on speed control of the motor servo system of ISM. Based on the classic PID control theory, increment-PI control algorithm or fuzzy PID control theory are also adopted in this research field .brother professional multi needleembroidery machine

Considering speediness, stabilization precision and overshoot of the ISM’s motor servo system which is a characterization of non-linear and strong coupled system, a comparison result among classic PID, increment-PI and fuzzy-PID shows that the effect of control by Fuzzy PID control algorithm is the best, increment-PI algorithm takes second place and the classic PID control algorithm is the worst .

The precise mathematical model of the object will be not required if fuzzy PID control algorithm is adopted. Instead, the fuzzy control rules, which would be used to determine the control volume, are built mainly based on the experience of the developers and experts. However, if the developer is not enough familiar with ISM, the application of fuzzy control will cost huge time on making the fuzzy control rules for ISM’s motor servo system, and the fuzzy control rules may be half-baked or even incorrect. Consequently, the effect of fuzzy control will be much worse than classic PID control [9]. An algorithm is needed when the developers just have a few knowledge of the ISM, which will spend much less time to realize the motor control. brother sewing and embroiderymachine

The differentiator in classic PID control improves the system’s fast response characteristic, but it amplifies the external disturbance, which has a bad impact on the reliability of the system. Hence, the differentiator is deleted in the application of increment-PI control considering the complex industry environment for the ISM’s well working. This method is simple and practical, but the dynamic response, speed smooth and reliability of the system needs improving if this method is applied in ISM.

Based on stitch filling of patterns of embroidery machines, we divide images into blocks according to colours, i.e. quantify the three components of H, S and I under the HIS coloured model. There are two sorts of quantification methods at present: uniformly-spaced quantification and non-uniformly-spaced quantification. Uniformly-spaced quantification makes uniformly- spaced partition of each component in its own domain. For example, tone H (0-360) can be divided equally into 6 portions and every 60 consist of one portion which can be divided into 6 categories, i.e. six-dimensional characteristic quantity. Because people have uneven perception of tone when seeing them, capturing characteristic quantity by non-uniformly-spaced quantification is a common method. Non-uniformly -spaced quantification can divide tone’s H space into 8 portions and saturation S and brightness I space into 3 portions according to people’s ability of visual recognition and determine accuracy of non-uniformly-spaced quantification of tones according to different ranges of the three components, people’s perception and wave length and frequency range of different colours.

wear of the sewing needles of embroidery machines defects can appear on the embroidery surface of the product. Therefore, it is necessary to schedule the moments of replacing the sewing needles of the embroidery machines based on the anticipation of their failure moments. Within this framework, the purpose of this study is to develop a fuzzy decision system for determining the moment of replacing of the sewing needles of embroidery machines, considering their amplitude of vibrations measured on the three axes of the Cartezian coordinate system.

Within this context, it is necessary to schedule the moments of replacing the sewing needles of the embroidery machines based on the anticipation of their failure moments. In the past years, through the development of different types of sensors, the scheduling of the replacement of components has been moved from a statistical approach to a condition-based maintenance. Modern diagnostic techniques use sensors that determine the state of the equipment by comparing the signals received from the sensors at a given moment with signals corresponding to their good functioning status

The software with the user graphic interface has been developed for the sewing path design in the embroidery industry. This new version of software is an advanced version of the last one and is incorporated many advanced new functions. The main purpose of the software is to create an easy and painless environment for the designer to create their own artistic sewing pattern with suitable sewing path. The resulting sawing path will be automatically transformed into a file with the absolutely or relatively coordinate value of each stitch point on the sewing path. The coordinate file will feed into the embroidery machine for the recreation of the design pattern on the surface of the product. Commercial graphic software does not provide the suitable function to transform each stitch point into their respective coordinate values. This drawback is resulted in the transformation process to be done by hand and by means of measuring each stitch point by designer - one point by one point. Most of the designed sewing pattern will involve more than hundreds of stitch points. It is a tedious and error-prone process for the designer and will deprive most of the design time away from the designer. This software will provide an immediately help for the designer to do the painful work of the process of the coordinate transformation. This will leave the designer to focus only on the artistic pattern design.

With the improvement of mechanization, both large-scale computerized embroidery machines and small-sized home embroidery machines have gained rapid development, which demonstrates development of computerized embroidery technology. Currently, it’s convenient to capture images while it’s hard to convert images into embroidery files. The latter job needs to be finished by professional software and expert pattern makers. Current home embroidery machines don’t have matched pattern and making software and converting images into embroidery files automatically still need to be explored. This thesis makes outline capturing in order to set a good foundation for making of pattern files by stitching filling based on the outline that can be recognized by embroidery machines. Click Here

Border detection plays a very important role in image processing. At present, border detection of gray images has gained remarkable achievement while that of coloured images still needs improvement. Gray images can be seen as two-dimensional and plane while coloured images can be seen as three-dimensional and stereo. When detecting border of coloured images, we can divide them into three two-dimensional gray images and thus apply border detection method of gray images into coloured images.

The wear of sewing needles is characterized by the changing of the size and shape of the needle, and the displacement of the needle axis relative to the vertical direction. Due to the wear of sewing needles, at high vibrations during the operation of the embroidery machines, there is wrinkling of the material on which the embroidery pattern is applied and breaking of the sewing thread can occur so that the embroidery machine has to be stopped. It is necessary to reposition the sewing needle with 6-10 stitch steps behind the trajectory to follow and the embroidery machine should be restarted. When the embroidering process restart, an overlap of the sewing thread occurs. Therefore, because of the wear of sewing needles defects appear on the embroidery surface of the product, the availability and thus the productivity of embroidery machines decrease, while the manufacturing costs are rising second hand stitching machine
