Automatic zero setting system and method for 2D reversing valve based on machine learning algorithm

The invention provides an automatic zero setting system and method for a 2D reversing valve based on a machine learning algorithm. The automatic zero setting system and method for the 2D reversing valve are used for solving the technical problems of long elapsed time and low accuracy of a manual zero setting method. The method comprises the following steps: fixing a reversing valve to be subjected to zero setting on a test bed and conducting a hydraulic pipeline; pushing the automatic zero setting mechanism through a guide rail to align and fix a coupling and a reversing valve element; shifting a transmission shaft to adjust the reversing valve into a working range; setting a passing flow value through an operation interface, starting a zero setting device, clicking a zero setting button, turning on a motor state indicator lamp, and carrying out automatic zero setting on the reversing vale through the zero setting system; inputting multiple parameters of a hydraulic system at the moment into a trained BP neur
