Predictive maintenance for cyber physical systems using neural network based on deep soft sensor and industrial internet of things

Abstract

Soft sensors are software libraries or techniques that can estimate status as well as predict important performance indicators. MVA (multivariate analysis) and ML methods have been developed in data-driven monitoring as well as fault detection method. Here this research proposes supervisory Just-in-time neural network (SJITNN) based CPS monitoring and predictive maintenance integrated with partial least squares key indicator (PLSKI) in linear systems and large scale complex systems which mitigate noise, complexity and improve the network robustness, accuracy of predictive maintenance, RMSE, recall, F-1 score and precision. Furthermore, by allowing user to design analysis chains themselves, framework presents a user-friendly predictive maintenance method. Aside from this, framework is based on containerization techniques to make platform versatile, durable, and scalable in a variety of production situations. The experimental results shows that the proposed technique obtained accuracy of 91.8%, precision of 87.6%, recall of 88%, F-1 score of 72% and RMSE of 50%.
