An acid value measuring device using a camera to collect colors

Abstract

An acid value measuring device using a camera to collect colors of the present invention relates to an acid value measuring device, which is composed of a body, a peristaltic pump and a titration tank, and the body panel is equipped with an ethanol quantitative peristaltic pump, an alkali quantitative peristaltic pump and an indicator Quantitative peristaltic pump, there is a magnetic stirring device on the left side of the body panel, and a main control unit on the left side of the magnetic stirring device. The rear end of the main control unit is fixed with the rear end of the body. Backflow device, there are cameras and light sources corresponding to each other on both sides of the titration tank. The present invention uses a camera for color collection, and only needs a stable light source in the process of color collection, which has low requirements on the light source; by comparing and analyzing the colors of the pictures, the analyzed electrical signal is then transmitted to the main control machine, and the main control unit The controller controls the ethanol quantitative peristaltic pump, alkali quantitative peristaltic pump and indicator quantitative peristaltic pump according to the analysis results until the titration is completed and the acid value is calculated.

Description

technical field [0001] The invention relates to an acid value measuring device, in particular to an acid value measuring device which uses a camera to collect colors. Background technique [0002] The existing acid value measurement device uses a color sensor to collect the color, and then judge the color change. This device needs a strong white light source, so that the light can pass through the liquid in the titration tank and irradiate the color sensor. The color value of the sample in the titration tank can be judged by the absorption of the three primary colors of white light by the sample in the titration tank; but if the color of the sample in the titration tank is too dark, the color transmitted to the color sensor will be weak or even black, making the sensor The color change cannot be detected; if the color of the sample in the titration cell is too light, the color transmitted to the color sensor will be strong, or even become white, which will also make the sens...
