[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables or cables. During the reproduction process of wires and cables, it is necessary to conduct tensile spot checks on the produced cables. During the spot check, the tensile test data is recorded, the test data curve is superimposed and analyzed, stored, printed, and the curve is drawn. A complete report is printed to control quality and make timely adjustments. During the production and processing process, the cable production is processed in an assembly line manner. The usual detection methods include testing the ends of the cables, testing the entire reel, or intercepting the cables. However, this detection method has a single sampling data and is time-consuming, labor-intensive, and material-intensive.
