Ship loader operation method and system based on encoder and RFID

The invention discloses a ship loader operation method and system based on an encoder and RFID, and the method comprises the steps: determining a corresponding linear transformation relation during the movement displacement of a cart, a rotation cantilever and a chute cylinder mechanism based on the data collected by the encoder; establishing a three-dimensional coordinate system; according to factory data of the ship loader, the distance between the center of a chute tube and the rotation center of a cantilever in the three-dimensional coordinate system, the distance between the rotation center of the cantilever and a seaside track on the Y axis and the maximum vertical distance between a discharge port of the chute tube and an XOY plane are obtained; angle parameters of a rotary cantilever are obtained, and real-time blanking point coordinates in actual operation are obtained through calculation; real-time blanking point coordinates are verified through data collected by the RFID module; and according to th
