Summary of the invention
Content of the present invention is to overcome all deficiencies in the above production run of weaving cotton cloth, and a kind of online quality monitoring method of textile weaving machine that carries out the cloth on-line monitoring based on computer pattern recognition principle is provided.
The object of the present invention is achieved like this: the online quality monitoring method of a kind of textile weaving machine 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 textile weaving machine cloth beam top, 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 cloth beam front end, digital image acquisition device camera lens is apart from 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 on the sliding bar and the batching speed of cloth beam.
Described standard cloth specimen storehouse and blemishes storehouse are in advance at the sampling of taking pictures of standard cloth specimen and cloth blemishes, and are organized into the storehouse later on through digitized processing, and storage is advanced 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 Weaving device 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.
