Multi-circle absolute angular sensor is one of the electronic core parts of robots and automobiles.TLE5012 B angular sensor
based on integrated giant magneto-resistive( i GMR) technology
can detect 360°variation of encapsulated magnetic field surface and accordingly realize non-contact angle measurement. A piecewise function algorithm integrating three-gear mechanical structure and TLE5012 B angular sensor is proposed to realize the high-precision and large-range non-contact measurement of the rotation position of the rotating shaft
accordingly decouple the detection range and the detection precision of the angular sensor. The experiment proves the proposed algorithm
based on piecewise function algorithm integrating three-gear mechanical structure
