The invention discloses a bucket wheel machine positioning system. The system comprises a walking detection system, a rotation detection system and a big arm detection unit; the walking detection system comprises a walking antenna control box, a walking position detection box and a walking coding cable, and the rotation detection system comprises a rotation antenna control box, a rotation positiondetection box and a rotation coding cable. The positioning method comprises the steps of (1) acquiring and calculating walking position signals; (2) acquiring and calculating rotation position signals; and (3) acquiring pitch angle signals. The walking coding cable and the rotation coding cable adopt the form of transmission reference lines and multi-strand transmission alignment lines, so that the measurement precision is effectively improved, signals are collected in an electromagnetic coupling mode, and the anti-interference capability of the system is improved by processing the walking position signals, the rotat
