2results about How to "Judgment stability" patented technology

The application discloses a kind of chromaticity instrument measurement display product chromaticity coordinate area determination method, including (1) chromaticity coordinate stability determination;(2) chromaticity target area optimization;(3) chromaticity target area attribution determination optimization;Traditional stability determination mode is single dimension, CIE1931 original chromaticity coordinate is provided in the form of discrete data with 1nm as wavelength interval, sampling interval is larger, precision is limited, traditional attribution determination is large in amount of calculation for chromaticity diagram of data point dense, according to covariance matrix construction minimum chromaticity ellipse, the spatial distribution characteristics of point set is determined by analysis chromaticity coordinate stability;Original chromaticity point is fitted using piecewise polynomial interpolation, and the coordinate precision is optimized to 0.01nm, two-stage rapid determination strategy is used, first based on polar angle realizes candidate sector preliminary screening, then in the local candidate sector obtained by preliminary screening, accurate determination is carried out using local ray method, and target area positioning of chromaticity coordinate is completed.

The utility model relates to the technical field of stratum monitoring, and discloses a stratum monitoring device for burying heat exchange tubes in middle and shallow layers, which comprises a ground inserting rod, a supporting circular plate, a protective frame and a protective cover, a supporting circular plate is welded to the top of the ground inserting rod, a protection frame is installed on the top of the supporting circular plate through screws, a first display screen and a second display screen are installed on the two sides of the bottom in the protection frame through bolts respectively, a timer is installed on one side of the inner wall of the protection frame through screws, and a protection cover is installed on the back side of the protection frame through connecting pieces and positioning screws. A horizontal displacement sensor and a longitudinal displacement sensor are mounted on the two sides of the inner wall of the protective cover through screws respectively, and an electric power storage box is mounted at the lower ends of the horizontal displacement sensor and the longitudinal displacement sensor through screws; according to the stratum monitoring device for burying the middle-shallow layer heat exchange tube, the stability of a soil body at a hole for burying the middle-shallow layer heat exchange tube is conveniently and accurately monitored, and the risk of hole collapse is effectively prevented.
