Claims

1. A system for measuring the color saturation of a plastic test piece, wherein the plastic test piece is a light-transmitting plastic test piece, comprising: a test object detection module, comprising: a middle box for placing the plastic test piece to be tested; a light-emitting diode installed at one end of the middle box to provide test light illuminating the plastic test piece; a color sensor installed at the other end of the middle box for measuring the color saturation parameters of the plastic test piece; an outer cover covering the entire middle box to block external light; the middle box and the outer cover are opaque; a microcomputer module, comprising: a housing including a base cover and a base; a microprocessor disposed on the base, controlling various electronic components according to preset program instructions; and a liquid crystal display screen installed on the base cover and connected to the microprocessor, displaying the color saturation parameters measured by the color sensor. The microprocessor executes the program instructions to cause the light-emitting diode to illuminate the plastic sample. The color sensor receives the light passing through the plastic sample and measures the colorimetric parameters of the plastic sample. The colorimetric parameters are then sent back to the microprocessor and displayed on the liquid crystal display screen. The microcomputer module is connected to the test object detection module via the light-emitting diode and the color sensor.

4. The system for measuring the color of plastic test pieces as described in claim 3, wherein, It further includes an artificial intelligence grading module, which is set in the server and connected to the reading and recording module. It receives the text file and uses a machine learning model to group the quality grades of the plastic sample based on the color parameters contained in the text file.

5. The system for measuring the color of plastic test pieces as described in claim 4, wherein the machine learning model is an unsupervised learning algorithm; the unsupervised learning algorithm is selected from at least one of aggregate hierarchical clustering, k-means algorithm and Gaussian mixture model.
