The invention relates to an incremental photoelectric shaft encoder data processing device and method and belongs to the technical field of the photoelectric shaft encoders. The incremental photoelectric shaft encoder data processing device comprises an amplifier, a comparator, an exclusive OR gate and a single-chip microcomputer (SCM). The photoelectric shaft encoder outputs two orthogonal sine and cosine signals SIN and COS. The COS is divided into two parts one of which is directly input into the SCM to be subjected to analog-to-digital conversion and the other one of which is converted into a square signal by the amplification of the amplifier and the comparison of the comparator, and the square signal is input into the SCM as a count signal. The SIN is divided into two parts one of which is directly input into the SCM to be subjected to analog-to-digital conversion and the other one of which is converted into a square signal by the amplification of the amplifier and the comparison of the comparator, and
