In the current production and manufacturing process of locomotive cables, conventional PID control algorithms are used to achieve intensive automatic processing. The control parameters used are fixed, and there is a large deviation in the thickness of the insulation sheath of the processed cables in dynamic scenarios. Therefore, a locomotive cable intensive automatic processing system based on fuzzy PID control is proposed. In terms of hardware, design for fully automatic cable processing machines and scanning detectors. In terms of software, a mathematical model for intensive machining process planning is constructed with the goal of minimizing machining, and the optimal process is solved through genetic algorithm. When processing according to the given process, it is necessary to inspect the cross-section of the wire core and insulation sheath, and calculate the eccentricity of the cable processing. Input the eccentricity detection value and the given value into the fuzzy PID control architecture, automatically adjust the control quantity based on real-time processing error, and achieve high-quality intensive automatic processing of cables. The test results show that the insulation sheath thickness deviation of the cables processed by the system is less than 0.5 mm, which meets the production requirements of locomotive cables.
