  • Patent number: 12282070
    Abstract: An insulation monitoring method and system for a traction battery and an apparatus are proposed to solve the problem of how to accurately predict a risk of insulation deterioration of the traction battery before the insulation deterioration occurs on the traction battery, so as to provide an early warning about failures in the traction battery. In this method, data statistics on a large amount of insulation resistance values within a long period of time are collected, and whether the traction battery has the risk of insulation deterioration is determined by analysis based on a data statistical result; and if the traction battery has the risk of insulation deterioration, alarm information is output. In this method, based on data statistical analysis performed on the large amount of insulation resistance values within a long period of time, insulation deterioration can be predicted before the insulation deterioration occurs on the traction battery.

  • Publication number: 20240383169
    Abstract: A transparent wood surface imprinting optical device is provided. A preparation method for the device includes cleaning and drying surfaces of transparent wood, spin-coating polymethyl methacrylate (PMMA) on a substrate of the transparent wood to obtain a PMMA layer, and spin-coating an ultraviolet (UV) glue on the PMMA layer to obtain a UV glue layer; placing the transparent wood on a silicon wafer, attaching a transparent grating array imprinting template on the UV glue layer, exposing the UV glue layer, and removing the transparent grating array imprinting after the exposing, thereby to obtain a grating-structure-based transparent wood; and replacing the grating structure imprinting template by a lattice structure imprinting template to prepare lattice-structure-based transparent wood. The diffraction efficiency of the grating structure and the lattice structure on the transparent wood are greater and more stable than those of PMMA substrates.

  • Patent number: 11946799
    Abstract: A distributed fiber-optic acoustic sensing system and a signal processing method. The distributed fiber-optic acoustic sensing system is based on a high spatial resolution distributed fiber-optic acoustic sensor. The interval between adjacent sensing units is centimeter or millimeter level. Through specific digital signal processing, signal enhancement can be realized, noise in the system and environment are suppressed, at the same time, problems such as interference fading is solved, and the sensor signal-to-noise ratio of subunits can be increased by two to three orders of magnitude. Each subunit can serve as an independent high-sensitivity sensor for sensing. The multiple subunits can form one or more new sensor arrays. The azimuth estimation and spatial orientation of signal sources can be realized by the array signal processing method.
