One of the big problems of today's manufacturing companies is the risks of the assembly line unexpected cessation. Although planned and well-performed maintenance will significantly reduce many of these risks, there are still anomalies that cannot be resolved within standard maintenance approaches. In our paper, we aim to solve the problem of accidental carrier bearings damage on an assembly conveyor. Sometimes the bearing of one of the carrier wheels is seized, causing the conveyor, and of course the whole assembly process, to halt. Applying standard approaches in this case does not bring any visible improvement. Therefore, it is necessary to propose and implement a unique approach that incorporates Industrial Internet of Things (IIoT) devices, neural networks, and sound analysis, for the purpose of predicting anomalies. This proposal uses the mentioned approaches in such a way that the gradual integration eliminates the disadvantages of individual approaches while highlighting and preserving the benefits of our solution. As a result, we have created and deployed a smart system that is able to detect and predict arising anomalies and achieve significant reduction in unexpected production cessation.
当今制造企业面临的一个大问题是装配线意外停止的风险。尽管计划周密、执行良好的维护将显著降低许多此类风险,但仍有一些异常情况无法通过标准维护方法解决。在本文中,我们旨在解决装配传送带上意外的承载轴承损坏问题。有时,其中一个承载轮的轴承被卡住,导致传送带,当然还有整个装配过程停止。在这种情况下,应用标准方法并没有带来任何明显的改进。因此,有必要提出并实施一种独特的方法,该方法结合了工业物联网 (IIoT) 设备、神经网络和声音分析,以预测异常。该提案以这样一种方式使用所述方法,即逐渐集成消除了个别方法的缺点,同时突出并保留了我们解决方案的优势。因此,我们创建并部署了一个智能系统,能够检测和预测出现的异常,并显著减少意外停产。
