Abstract

The invention provides a system and a method for oil color detection. The system comprises an optical processing unit and a computing device. The optical processing unit comprises a light source, a first collimating lens, sample slots, a cuvette, a cylinder lens, a grating and a linear array CCD sensor. According to the system and the method, a light path is built on the basis of respective property of the optical elements, the linear array CCD sensor is used for acquiring spectroscopic data and sending the same to the computing device through a USB data line; curve of spectrum of oil to be detected is measured by means of mercury lamp marking; spectral analysis is carried out by a logarithmic method, so that color value of chromatic value of the oil to be detected is computed. Compared with the existing lovibond colorimetry test, the method has the advantage that automatic measurement of oil color is achieved, influence from personal error and environmental factor during the visual measurement is avoided, and measurement precision and measurement speed are increased. By the measurement method of averaging measured results based on multiple measurements, reliability of measurement results is improved.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, and more particularly, to a system and method for detecting the color of grease. Background technique [0002] The quality of oil is related to people's health and the sales of oil in my country, and its quality has become a key factor affecting the competitiveness of the oil and oil industry. As an important appearance basis for oil grading, pricing and consumer purchase of oil, color is one of the important indicators of oil quality testing. The determination of oil color can improve oil processing technology and conditions, provide security for food industry and enhance my country's import and export trade. [0003] At present, the Lovibond color device is an international unified standard for measuring the color of oils and fats. The Lovipon colorimetric method uses the visual method to match the color of the oil sample with the synthetic color of the Lovipon standard colori...
