High-speed spectrometer safety monitoring device and method based on image processing

Abstract

The invention provides a high-speed spectrometer safety monitoring device based on image processing, which can automatically and accurately identify a fine gap between an excitation hole and a sample,and is simple in structure and suitable for popularization and application. Meanwhile, the invention discloses a high-speed spectrometer safety monitoring method based on image processing. The devicecomprises an image acquisition device, a light source and an image processor, cameras of the image acquisition device are symmetrically mounted on two sides of an excitation table of the spectrum analyzer through mounting brackets respectively; wherein the light source is arranged right above an excitation hole of the spectrograph, and the projection of the central point of the light source is the excitation hole; the image processor is in communication connection with the image acquisition device; image data acquired by the image acquisition device are transmitted to the image processor, theimage processor analyzes and recognizes the image data, and once it is recognized that the excitation hole is not completely covered by a workpiece, it is judged that a safety problem exists, and real-time alarming is performed.

Description

technical field [0001] The invention relates to the technical field of spectral analysis industry, in particular to an image processing-based high-speed spectrometer safety monitoring device and monitoring method. Background technique [0002] Spectrum analyzers are widely used in electric power, metallurgy, steel and other industries because of their advantages such as fast analysis speed, low detection limit, good accuracy, simultaneous detection of multiple elements and low sample consumption. The working process of the spectrum analyzer is: put the sample on the excitation hole, the excitation light source emits reflected light through the excitation hole and emits light to hit the sample; the sample is evaporated and atomized (transformed into gaseous atoms) under the action of energy , and excite the outer electrons of gaseous atoms to a high energy state; when transitioning from a higher energy level to a lower energy level, the atom will release excess energy and emi...
