| 摘要 |
<p>The invention relates to a method of monitoring a moving linear textile formation (4) in which the monitored linear textile formation (4) moves across a radiation flux emitted by a radiation source (3) in the direction towards an optical sensor (1) comprising a raw of radiation-sensitive measuring elements (10) and thus producing on the optical sensor (1) a shadow of the moving linear textile formation (4) to be evaluated for determining the required parameters of the monitored moving linear textile formation (4). The invention consists in that the monitoring of the moving linear textile formation (4) by the optical sensor (1) is carried out with a radiation intensity at which the radiation-sensitive measuring elements (4) of the optical sensor (1) are irradiated at least at the level of their saturation, thus permitting for the evaluation of the function of the optical sensor (1) a more exact division of the radiation-sensitive measuring elements (10) into those completely shadowed, those partly shadowed and partly irradiated, and those completely irradiated, with the ensuing more exact definition of the position of the delimitation lines of the moving linear textile formation (4) projected on the optical sensor (1), these delimitation lines being in more exact coincidence with the real state of the moving linear textile formation (4) which leads to a simpler and more exact determination of the parameters of the moving linear textile formation (4). The invention relates also to a device for carrying out the method. &lt;IMAGE&gt;</p> |
