Summary of the invention
Content of the present invention is to overcome all deficiencies in the above printing and dyeing production run, provides a kind of and carries out printing and dyeing industry semi-manufacture and the online quality monitoring method of finished product based on computer pattern recognition principle.
The object of the present invention is achieved like this: the online quality monitoring method of a kind of dyeing and printing products based on computer pattern recognition principle, it is characterized in that: described method is to adopt a kind of digital image acquisition device, this digital image acquisition device adopts line array CCD or cmos sensor, or employing area array CCD or cmos sensor, described digital image acquisition device is fixed on the sliding bar of printing and dyeing related running roller or cloth beam top in the middle of each technological process, this digital image acquisition device is done back and forth on sliding bar and is reciprocatingly slided, described digital image acquisition device camera lens is towards the cloth cover of running roller or cloth beam front end, digital image acquisition device camera lens is apart from running roller or the cloth beam cloth cover certain distance (distance of concrete distance, adjust to a position the most effective according to the focal length of the camera lens on the digital image acquisition device), this digital image acquisition device is according to the frequency of taking pictures in the unit interval of setting, on the one hand reciprocal back and forth again motion on sliding bar, carry out continual taking pictures at the cloth cover in the motion simultaneously, linear array of being gathered or face battle array digital pictures pass to the site disposal main frame in real time
Be provided with standard cloth specimen storehouse and blemishes storehouse in the described site disposal main frame, according to the computer picture recognition principle, carrying out the identification of cloth cover blemishes image comparison handles, thereby carrying out the textile blemishes judges, in case judge blemishes, send alerting signal even allow board shut down, and, report out the type of the blemishes on the cloth according to the blemishes type of coincideing in the site disposal main frame blemishes storehouse; And, calculate and point out the particular location that blemishes take place according to the position of taking pictures of nearest digital image acquisition device, the speed that reciprocatingly slides and board travelling speed on sliding bar.
Described standard cloth specimen storehouse and blemishes storehouse are the standard cloth specimens that produced at each road technology of printing and dyeing in advance and the sampling of taking pictures of cloth blemishes, and pass through digitized processing and be organized into the storehouse later on, store in the site disposal main frame,
Described site disposal main frame band LCDs and keyboard, and possess external communication interface and external memory interface.
Adopt the inventive method; can be in equipment running process; the quality of the inspection product that does not stop all the time; judge the blemishes of product; produce in case find blemishes, send all kinds of suitable alerting signal notifying operation personnel immediately, can pass through the shutdown bus interface of dyeing apparatus simultaneously as required automatically; allow equipment downtime, and point out blemishes type and blemishes occurrence positions.Thereby substitute the tour observation that people-to-people contacts a large amount of in this production run are hurried back and forth and carried out with this.Greatly improve labor productivity, reduce the generation of substandard products, reduce labour's use amount.

Embodiment
The online quality monitoring method of the dyeing and printing products based on computer pattern recognition principle that the present invention relates to, be to adopt a kind of digital image acquisition device, this digital image acquisition device adopts line array CCD or cmos sensor, or employing area array CCD or cmos sensor, described digital image acquisition device is fixed on the running roller or a sliding bar above the cloth beam of each technological process of printing and dyeing, this digital image acquisition device can be according to the setting of program, by motor-driven, on sliding bar, do back and forth and reciprocatingly slide, described digital image acquisition device camera lens is towards the cloth cover of running roller or cloth beam front end, digital image acquisition device camera lens is apart from running roller or the cloth beam cloth cover certain distance (distance of concrete distance, adjust to a position the most effective according to the focal length of the camera lens on the digital image acquisition device), as Fig. 1,2.According to the continuous scrolling of producing middle roll or cloth beam, this digital image acquisition device is according to the frequency of taking pictures in the unit interval of setting (be set at per second such as the linear array digital image acquisition device of 2000 pixels and take pictures 500), this digital image acquisition device is according to the reciprocating speed of setting (at the uniform velocity sliding 1 meter such as setting per second), carry out continual taking pictures at the cloth cover in the motion, linear array of being gathered or face battle array digital pictures pass to the site disposal main frame in real time, be provided with standard cloth specimen storehouse and blemishes storehouse in the described site disposal main frame, according to the computer picture recognition principle, carry out the identification of cloth cover blemishes image comparison and handle, judge (the cloth specimen picture and the blemishes storehouse in the on-the-spot main frame that photograph do not stop to compare processing all the time) thereby carry out the textile blemishes.In case judge blemishes, then can send alerting signal immediately even allow board shut down, and, report out the type of the blemishes on the cloth according to the blemishes type of coincideing in the site disposal main frame blemishes storehouse; According to the position of taking pictures of nearest digital image acquisition device, the speed that reciprocatingly slides and board travelling speed on sliding bar, calculate and point out the particular location that blemishes take place.Described standard cloth specimen storehouse and blemishes storehouse are in advance at the sampling of taking pictures of printing and dyeing each road technological standards cloth specimen and cloth blemishes, and pass through digitized processing and be organized into the storehouse later on, store in the site disposal main frame.
