This paper describes a novel wavelet-based approach to the abrupt fault detection and diagnosis of sensors. By use wavelet transforms that accurately localize characteristics signal both in time frequency domains, occurring instants abnormal status sensor output can be identified by multiscale representation signal. Once are detected, distribution differences energy on all decomposed scales before after used claim classify faults. Synthetic data simulated means computer using real-word from...
Wear debris generated in a pitting process of planetary gearboxes carries valuable information about health status. However, RGB images online wear are often affected by image blur caused Gaussian noise, high-frequency and other random noises besides including bubbles lubricating oil, dark oil contamination, the temperature rise electronic components. To address these issues, this work, an denoising model WVBOD was proposed based on fusion wavelet, variational mode decomposition non-local...
The maps used for the path planning of mobile robots are mostly grid maps, which generated through independent design or sensor measurement to obtain relevant information and then modeling. To robot motion more quickly, this paper proposes a method ant colony algorithm under non-standard environment map. map is standard design, optimized by no safety distance added obstacle box selected selected, carried out algorithm. In addition, mutual correspondence between real was solved adding...
Wear debris image processing techniques are increasingly employed in health monitoring and fault diagnosis for mechanical equipment. However, during the acquisition storage of wear images, substantial noise is often introduced, leading to significant errors subsequent feature extraction status assessment. Moreover, denoising process frequently encounters algorithmic shortcomings, resulting blurred boundary information, artifacts, incomplete boundaries, greatly hindering further research on...
Health state monitoring is important to many large machines. Which can real-time monitor the equipment operation condition, give early warning of possible failures, and evaluate remaining use life equipment. Planetary gear transmission system widely used in various fields works under harsh environment for a long time, resulting wear tear key parts, further affect normal In this paper, planetary gearbox condition experiments were conducted varying conditions by using oil system, data was...
Based on the planetary gearbox condition monitoring experimental platform, this paper proposes an organic algorithm for wavelet algorithm, two-dimensional variational mode decomposition and median filtering image information of abrasive particles collected during on-line oil wear debris monitoring. Combined denoising Through experiment comparison with other algorithms, it is proved that can have a good effect image, ensure edge detail to obtain better visual effect.
Corporate social responsibility (hereinafter referred to as “CSR”) sometimes does not directly affect enterprise performance but through some mediator variable. reputation and brand value have chain-mediating effects in the influence mechanism of CSR on performance. Theoretically, this paper broadens scope study performance, deeply explores internal between them, opens “black box” process transforming into Practically, it can encourage Chinese enterprises actively undertake CSR, strengthen...
