AI Technical Summary

Technical Problem

Existing technologies for testing the performance of petroleum products suffer from lag and inaccuracy, and the cooling process is time-consuming, making it impossible to accurately determine the pour point and freezing point.

Method used

A small, portable testing instrument is used to acquire the spectral characteristics of the test sample in real time through a spectral detection module. Based on the detection command, a rapid cooling signal is output, and the spectral characteristics are used to determine whether the test sample has solidified. The cooling rate is dynamically adjusted, and the liquid surface movement is analyzed by a camera module. By integrating multiple detection methods, accurate pour point and freezing point can be obtained.

Benefits of technology

It improves the accuracy and efficiency of test results, reduces cooling time, avoids skipping the pour point or freezing point due to excessive cooling speed, and achieves the accuracy of automation and multiple detection.

Abstract

The application relates to the technical field of oil product performance testing, in particular to a small portable detection tester control method, device and equipment and a storage medium, which comprises the following steps: obtaining a detection instruction; acquiring the spectral characteristics of a test product in real time; outputting a rapid cooling signal based on the detection instruction; judging whether the test product appears to be solidified based on the spectral characteristics in real time; if the test product appears to be solidified, stopping the output of the rapid cooling signal and outputting a first slow cooling signal. The application has the effects of improving the automation degree, improving the accuracy of test results and reducing the waste of time.
