The invention provides a non-contact life signal processing method in a strong clutter environment, and belongs to the field of data processing.The method comprises the steps that extreme points in a signal data sequence of a user and first and last signal data are recorded as to-be-corrected data; obtaining an amplitude adjustment parameter and a slope adjustment parameter of each piece of to-be-corrected data according to a numerical value difference and an acquisition time difference between each piece of to-be-corrected data and the to-be-corrected data on the left side and the right side of the to-be-corrected data; and combining the numerical value of the to-be-corrected data to obtain a corrected value of the to-be-corrected data, thereby obtaining upper and lower envelope lines. The invention aims to solve the problem that the signal data of a user is processed by an EMD (empirical mode decomposition) algorithm due to the fact that an upper envelope line and a lower envelope line which are obtained through extreme points in a signal data sequence are greatly influenced by noise because the noise in an environment where the user is located has a great influence on the signal data of the user. And the accuracy of the obtained heart rate signal and respiration signal is low.

This utility model discloses a quick-installation high-purity pressure reducing valve, including a pressure reducing valve body. Three docking seats are integrally formed on the surface of the pressure reducing valve body. Two docking seats have docking pipes inserted into their outer sides. Insertion holes are provided on the outer sides of the docking seats, and the docking pipes are inserted into the corresponding insertion holes. Locking grooves are provided on both sides of the inner cavity of each insertion hole. A groove is provided at the top of the inner cavity of each locking groove. A movable cavity is provided on one side of the inner cavity of each locking groove. The insertion holes, locking grooves, and grooves are interconnected. A fixing rod is fixedly connected to one side of the inner cavity of the movable cavity. A locking block is slidably installed on the surface of the fixing rod. This utility model adopts a structural design that enables quick installation and disassembly. The entire quick-installation docking assembly allows for rapid installation and disassembly of the pipes and valve body, improving installation and disassembly speed, increasing maintenance efficiency, reducing maintenance costs, and featuring a simple structure and low manufacturing cost.

The present application belongs to the technical field of hot-rolled section steel finishing, and discloses a section steel unqualified product classification and removal collection production line capable of improving production rhythm. The production line comprises a length detection device, a first inspection rack, a second inspection rack, a short-length product removal collection rack, a quality defect product removal collection rack and a stacking rack. When a rolled piece is detected as a short-length product by the length detection device before entering the first inspection rack, the rolled piece enters the second inspection rack through the first inspection rack, the short-length product is removed and collected through the short-length product removal collection rack, the remaining rolled pieces are removed and collected for quality defect products through the quality defect product removal collection rack, and the qualified products enter the stacking rack. When the rolled piece is not detected as a short-length product by the length detection device before entering the first inspection rack, the rolled piece enters the first inspection rack or the second inspection rack, the quality defect products in the rolled piece are removed and collected through the quality defect product removal collection rack, and the qualified products enter the stacking rack.
