Fault Classification by Intelligent Systems to Ensure Electromagnetic Compatibility of Vehicles

Abstract: The problem of electromagnetic compatibility is relevant to many systems, for example, an automotive ignition. The ignition system is a complex technical intelligent control system constituting the car's electrical equipment. It is known that the more complex the system, the more vulnerable it is to electromagnetic interference, so more costs are required to ensure the stability of its operation in the conditions of electromagnetic interference (EMI). Accordingly, our goal is to meet the requirements of the maximum permissible level for radiated interference by solving the problem of classification of faults from EMI by intelligent sensors. In this work, intelligent sensors were selected and tested by performing data analysis that detects the excess of an EMI level with a classification error of 5-10%.

Design and evaluation of a wireless sensor system for remote mechanical parts monitoring

Abstract: Newly developed techniques for intelligent sensor systems make it possible to register the mechanical wear-out of parts, such as band saws, ball screws and gearbox reducers, by collecting working signals from them, such as vibrations and preload pressure and temperature changes. To build an accurate wear model, we need to log as many real signals as possible from numerous parts in machine tools. This raises a substantial problem: How can we collect a large number of real signals from the parts installed in many machine tools — which could be located anywhere in the world — and aggregate data to use in constructing a wearing model, as well as enabling remote systems analysis and send warnings if the parts are worn? In this study, based on our previous work, we design a special embedded system to realize a cloud-based service that logs mechanical wear-out of parts. Both short and long range wireless communications are tested to evaluate its performance. The proposed system can be used to collect operating signals regarding mechanical wear-out of parts and can allow manufacturers to track state of wear and send warnings to tool owners before wear-out.

Superconductor digital electronics technology for sensor interfacing at the FLUXONICS Foundry

Abstract: The integration of superconductor digital electronics together with superconducting sensors can enable smart multi-channel sensor arrays. Applications of such sensors range from basic astrophysical research to advanced security screening devices. The main advantage of superconducting sensor interfaces is the very low power consumption in combination with a very low noise level; both are required in order to keep the excellent superconducting sensor performance without distortions. The FLUXONICS Foundry technology has been optimized with respect to electronic interfaces circuits for analogue sensor readout and signal multiplexing. In this work, we describe this new interface technology and present a comparison with our standard RSFQ technology.

Human-Tracking Behavior of Mobile Robot Using Multi-Camera System in a Networked ISpace

Abstract: The paper proposes a human-following behavior of mobile robot and an intelligent space (ISpace) is used in order to achieve these goals. An ISpace is a 3-D environment in which many sensors and intelligent devices are distributed. Mobile robots exist in this space as physical agents providing humans with services. A mobile robot is controlled to track a walking human using distributed intelligent sensors as stably and precisely as possible. The moving objects is assumed to be a point-object and projected onto an image plane to form a geometrical constraint equation that provides position data of the object based on the kinematics of the intelligent space. Uncertainties in the position estimation caused by the point-object assumption are compensated using the Kalman filter. To generate the shortest time trajectory to track the walking human, the linear and angular velocities are estimated and utilized. The computer simulation and experimental results of estimating and trackinging of the walking human with the mobile robot are presented.
