This invention relates to the technical field of substance detection, and discloses an intelligent detection method and system for seabuckthorn vinegar flavor substances based on gas chromatography-mass spectrometry. By dynamically acquiring chromatographic and mass spectrometric combination images of seabuckthorn vinegar flavor substance detection points in the fermentation tank based on the coordinate information of the detection points, combined with sampling equipment, a gas chromatography system, and a mass spectrometry system, the system adaptively acquires chromatographic and mass spectrometric combination images of seabuckthorn vinegar flavor substances at different spatial locations within the fermentation tank. Based on the chromatographic and mass spectrometric combination image information of the seabuckthorn vinegar flavor substance detection points in the fermentation tank, and combined with intelligent image recognition algorithms and chromatographic and mass spectrometric combination information of different substance characteristic standards based on big data storage, the system intelligently detects the types and concentrations of flavor substances at the detection points in the fermentation tank, achieving intelligent, comprehensive, and scientific detection of seabuckthorn vinegar flavor substances based on chromatographic and mass spectrometry.

This invention discloses a cable production identification and monitoring system and method based on cable images, belonging to the field of image recognition technology. The system includes: acquiring a sequence of cable surface depth images to construct a grayscale surface map along the cable surface depth direction; using the central ridge of the grayscale surface map as a dynamic axis of symmetry, detecting candidate pixels through multi-scale morphological top-hat transformation to form a symmetrical residual distribution map; combining the eight-neighbor gradient direction field and Hessian matrix curvature to remove false defect points, obtaining an effective image, and inputting it into a pre-trained multi-task neural network to simultaneously output a defect segmentation mask and category label; generating a three-dimensional mesh model with dimensional accuracy through Poisson surface reconstruction; and finally, using the physical coordinates of the defect center to drive a laser marking machine to mark a QR code containing key information, which is then associated and stored in a blockchain database. This application improves the accuracy and efficiency of defect identification, realizing the quantitative characterization and full lifecycle management of defects.

This invention relates to the field of road construction technology, specifically disclosing a road construction surveying device and method, comprising: a surveying frame; a sleeve mounted on the surveying frame, the bottom of the sleeve being in contact with the surveyed ground, and an end cap on the top of the sleeve; a drilling mechanism, including a power component mounted on the surveying frame, a main shaft driven by the power component to rotate and slide vertically along the end cap, and a drill rod located at one end of the main shaft inside the sleeve; and a sampling pipe mounted on the end cap and communicating with the inside of the sleeve. This invention solves the problem in traditional rock and soil surveying processes where dust generated during drilling directly disperses into the air, causing pollution to the surrounding environment.
