Extended hand-pulling type transposing zither

The invention relates to an extended hand-pulling type transposing zither which comprises a hand-pulling type transposing zither main architecture and part analysis equipment, wherein the hand-pullingtype transposing zither main architecture comprises a transposer, a left non-tuning region, a left main playing region, a center code, a right main playing region, a right non-tuning region, an S-shaped Yueshan part, a straight inclined Yueshan part, a left zither frame leg and a right zither frame leg; the left main playing region and the right main playing region are respectively formed at bothleft and right sides of the center code; the left non-tuning region is formed at the left side of the left main playing region; the right non-tuning region is formed at the right side of the right main playing region; the S-shaped Yueshan part is arranged at the left side of the left non-tuning region; and the part analysis equipment is used for identifying various part targets in a foreground image on the basis of image features of various parts of the transposing zither and judging whether part type missing exists on the basis of an identification result. According to the invention, electronic auxiliary functions of the transposing zither can be effectively extended.
