Example Embodiment

[0027] The present invention will be further described in detail below in conjunction with the drawings.

[0028] Such as figure 1 As shown, the grating-type near-infrared detector based on the cloud platform of the present invention is composed of a light source, a beam splitter, a sample box, a motor, an optical fiber group, a monochromator, an amplifier, an A / D converter, a controller, a host computer, and a cloud platform composition. The light source adopts a halogen lamp. The light source, beam splitter, sample box, optical fiber group, and monochromator are arranged in sequence, and the monochromator is set close to the optical fiber group. The beam splitter is used to receive light from the light source and collimate the received light into parallel light. On the sample box, the sample box contains the sample to be tested. The light passing through the sample box carries rich sample information into the optical fiber group, and the light carrying the sample information en...

Abstract

The invention relates to a cloud platform-based optical grating near-infrared detector, relating to the field of grain, cereal constituent and content analysis and solving the problems that the existing detector has small storage capacity and data cannot be found out at any time at any place. Light of a light source is collimated into parallel light by a spectroscope to irradiate a sample box, light carried with sample information is converged into an optical fiber group and transmitted to a monochromator, light is collimated by a first spectroscope and split into light with different wavelengths by the light grating so as to be irradiated to a second reflecting mirror and converged into the detector, the light spectrum signal is converted into a weak current signal by the detector to be transmitted to an amplifier, the amplifier is used for calculating and amplifying and transmitting the weak current signal to an A/D converter, the A/D converter is used for converting the calculated and amplified weak current signal into a digital signal to a controller, and an upper computer is used for reading and analyzing the spectrum data; and the upper computer sends the spectrum data to a cloud storage or sends the spectrum data into cloud calculation for processing and then sends the processed spectrum data into the cloud storage, and terminal equipment logs in a server through a query terminal to find out original or processed spectrum data. The data storage capacity is expanded, and the random and any-place search can be realized.

Description

technical field [0001] The invention relates to the technical field of food and grain composition and content analysis, in particular to a cloud platform-based grating near-infrared detector. Background technique [0002] With the improvement of people's living conditions, people's health is threatened by more and more aspects. The most important thing is food, grains and other food that people need for life. Therefore, it is particularly important to detect the composition and content of food and grains. . At present, many detection instruments for detecting the composition and content of grains and grains have been developed at home and abroad, such as far-infrared, mid-infrared, and near-infrared spectrometers, etc., by detecting the vibration spectrum generated by sample particles under infrared light irradiation, The analysis of grain and grain composition and content has the characteristics of no damage to samples, no reagents, no pollution to the environment, and eas...
