This invention relates to the field of agricultural product sorting technology, specifically a fully automatic near-infrared spectroscopy online detection and sorting system. It includes a conveying mechanism and an air pump located on the side of the conveying mechanism. An image acquisition device is installed at the upper end of the conveying mechanism, and a sampling detection mechanism is installed on the side of the image acquisition device. A flipping mechanism is installed inside the conveying mechanism and below the image acquisition device. By designing a continuously operating conveying mechanism, walnut products can quickly reach the detection area. Simultaneously, the image acquisition device and the sampling detection mechanism are integrated into the system, allowing both to simultaneously detect the product, shortening the detection time and achieving efficient detection. Considering that acquiring images from a single angle may not fully capture product information, a flipping mechanism is designed to acquire product images from different angles. The sampling detection mechanism performs sampling detection on the product, and combined with near-infrared spectroscopy technology, more parameter information of the product is obtained, thereby improving the accuracy of the detection.

This disclosure provides transabdominal fetal oximetry (TFO) that uses frequency-modulated continuous-wave (FMCW) time-domain near-infrared spectroscopy to measure time-resolved reflectance values of light signals collected from a maternal-fetal multilayer tissue structure. In various embodiments, the disclosed FMCW time-domain near-infrared spectroscopy is configured to function as an optical interferometer that uses two frequency-swept laser sources of different center wavelengths λ1 and λ2 as probe lights to detect optical property in vascular tissues of the maternal-fetal multilayer tissue structure. The FMCW near-infrared spectroscopy is configured to collect light signals returned from the multilayer structure and generate a time-resolved reflectance curve based on the collected light signals.

This invention discloses a data analysis-based method for maintaining VIGS activity in chili pepper fruits, belonging to the technical field of VIGS activity maintenance in chili pepper fruits. The method includes the following steps: Multimodal data acquisition: After VIGS inoculation of chili pepper fruits, a multimodal sensor array is deployed to continuously collect environmental factor data of the microenvironment where the fruit is located at a preset first frequency. This invention, by deploying a multimodal sensor array, achieves real-time and continuous acquisition of microenvironmental factors and physiological state data of chili pepper fruits. Combined with near-infrared spectroscopy and a self-calibration mechanism, it significantly improves the estimation accuracy of the target gene silencing efficiency index and the robustness of data acquisition. Based on a nonlinear mixed-effects model and Bayesian parameter inference method, this invention constructs an individualized dynamic decay model of VIGS silencing activity, which can update the silencing efficiency decay curve of individual fruits in real time, accurately predict the remaining maintenance time, and improve the targeting and effectiveness of regulation.
