Industrial chemical intelligent titration method and industrial chemical intelligent titration system based on image color information extraction

Abstract

The invention provides an industrial chemical intelligent titration method and an industrial chemical intelligent titration system based on image color information extraction, which can intelligentlyjudge a titration end-point and improve the titration efficiency. The method comprises the methods of establishing a rule database, detecting online and updating the rule database. Related parameterssuch as a slow dropping point S are acquired, fitting is performed on the slow dropping point to acquire a slow dropping point curve f(V), and then a slow dropping point prediction titration amount isacquired, thereby accurately judging the titration end-point. The system comprises a chemical titration intelligent processing unit, a titration mechanism and an image acquisition unit. The titrationmechanism comprises a monitoring device, a light blocking plate, an embedded controller, a feeding device, a titration device and a stirring device. the industrial chemical intelligent titration system and the industrial chemical intelligent titration method are higher in the detection efficiency and higher in the detection precision compared with detecting the concentration of a sample with a manual titration method when detecting the sample, improve the titration efficiency and the detection precision, and objectively and accurately reflect the chemical titration result.

Description

technical field [0001] The invention relates to the technical field of chemical concentration detection in industry, in particular to an industrial chemical intelligent titration method and system based on image color information extraction. Background technique [0002] In the process of sample concentration detection in the metallurgical and chemical industry, it is generally necessary to add a buffer, masking agent or indicator to the chemical reaction solution in order to observe the color change in the chemical reaction, thereby judging the titration end point of the chemical reaction . The subjective factors of the laboratory technician and the proficiency of "hand" and "eye" coordination will affect the accuracy of chemical titration end point detection. The potentiometric titration method can make accurate judgments under normal circumstances, but the analysis time is long, the sensitivity is limited, and the residual current affects the detection effect at low conc...
