Multi-Channel Detection System for Joint Position Based on Optical and Orthogonal Decoding

Abstract:

The multi-channel joint position detection system of measuring arm is of high precision, multi-channel and other special characteristic. This system uses hardware called DSPic30F microchip as the processing core. The detection system adopts optical encoder as joint angle sensor and orthogonal decoding and reversible chip HCTL-2032 to multi frequency the detected signal, which greatly reduces the system error and enhances the detection precision. Experiments of joint position detection are realized. Thirty times repeated experiments show that the maximum error is 0.009 °and the maximum relative deviation is 40.9 × 10-3 /%.
