1results about How to "Improve experiment safety" patented technology

This invention belongs to the fields of mechanical automation and machine vision recognition technology. It discloses a stability heating test system and method for automated test tube extraction and boundary recognition. The system includes a mechanical motion and gripping unit, a heating and temperature control unit, a machine vision recognition unit, and a central control unit. It enables automatic placement and retrieval of test tubes between the placement and heating positions, precise control of the test temperature and over-temperature protection, and automatic recognition of the endpoint of test paper color change based on machine vision. The method achieves intelligent determination and alarm of the color change endpoint through image acquisition and processing, multi-test tube positioning, test paper area extraction, and color similarity analysis based on HSV color space and Mahalanobis distance. This invention solves the problems of low efficiency, large subjective error, and high safety risks in traditional manual operation, realizing full automation, digitalization, and unmanned operation of the stability heating test process, and improving the accuracy and repeatability of test results.
