“…Hence, if it is possible and economically justified, in condition monitoring, it is recommended to use different signals at the same time, e.g., vibration, electrical and acoustic signals. More detailed information about such an approach can be found in [22,29,30].…”

Bucket elevators generally operate on a 24/7 basis, and for this reason, one of the main requirements is their high reliability. This reliability can be ensured, among other things, by assessing the technical condition of drive assemblies and working assemblies and taking appropriate measures. Carrying out diagnostic measurements enables periodical monitoring of those mechanisms. Vibroacoustic methods are usually employed in operating conditions to measure vibration velocity and acceleration at specific points, and are used as diagnostic signals. This paper presents the results of tests of the intensity of vibrations generated in the drive unit of a large industrial bucket elevator. The analysis of the results in the time domain and frequency domain served as the basis for evaluating the suitability of the drive, and thus the elevator, for long-term operation.

“…On the other hand, a combination of signals used in such analyses can be more beneficial for the diagnosis than when selected signals are used separately. An experimental study of the fusion of electrical, acoustic and vibration analysis is presented, among others, in [14]. In addition, the operating gears can produce disturbances in the vibroacoustic signal, e.g., because of a lower quality of their surfaces [15], while the most common failures within gear transmissions involve the teeth, which are usually damaged by fractures occurring at their base or by pitting [16].…”

Bucket elevators are applied in many industries for bulk material handling. One of the main requirements for these devices is their high operational reliability. This applies in particular to power units that must operate continuously without failure. This article presents a comparative assessment of the drive units of two bucket elevators. The vibration intensity of their bearing units was used as the basis for the comparison. The evaluation was carried out using three independent methods based on the vibration velocity analysis: in the time domain, in the frequency domain and using the probabilistic approach.

“…In (Zhou and Peng (2020)), the authors apply multi sensor fuzzy information fusion for monitoring of a chemical plant. In (He et al (2019)), new methods to monitor performance of wind turbine gearbox and bearing are presented by using Gaussian model based information fusion on acoustic, vibrational and electrical data. In (Zhang et al (2020)), an information fusion framework is proposed to fuse multiple heterogeneous data to access control room operator performance.…”

Information fusion for decision making

Making intelligent decisions in autonomous systems often requires the use of all available information. This information generally comes from multiple sources and may be expressed through multiple modalities. This thesis presents a collection of different approaches for processing and fusing sensor data that have been developed for systems that enjoy multiple sensors and/or sensing modalities. Within these approaches we focus on information fusion in the form of emerged communication for team tasks in multi-agent systems in the first part. After that we investigate information fusion in the context of active sensing by treatment of an agent as a hybrid switched system. Then we look at information fusion in a probabilistic graphical modeling framework. Here information from multiple sensors can be fused through joint probability distributions borrowing notions of causality. These notions of causality are used for deriving intelligent fusion rules that can either help in performance monitoring/anomaly detection or data abstraction by hierarchically combining information across multiple sensors. Finally we propose a novel modular approach for fusion of information from vision (RGB images) and language modalities (user input text) in order for a robot to follow and execute natural language instructions in a household environment. Our proposed technique achieves state of the art accuracy in the popular, realistic Ai2Thor environment based on a Unity based simulator.
