提出了一种绝对式多磁极磁电编码器的实现方案，采用线性霍尔和开关霍尔组合使用的方式去测量2组极对数互质的多磁极永磁体之间的位置关系和绝对角度。结合现有的磁电编码器成果，确定了磁电编码器的绝对角度计算方案。通过理论分析、作图分析以及与理论推导结合的方式确定了永磁体磁极的数量关系、霍尔元件的布置方式以及具体的磁极识别过程。并利用MATLAB软件模拟磁电编码器的工作过程，证明了绝对角度计算方案的可行性。

A scheme of absolute multi-pole magneto-electric encoder is proposed. The linear Hall and switch Hall sensors are used to measure the position relationship and absolute angle between the two groups of multi-pole permanent magnets with coprime number of pole-pairs. The absolute angle calculation scheme of the magneto-electric encoder is determined based on the existing achievements of the magneto-electric encoder. Then through the combination of theoretical analysis, drawing analysis and theoretical derivation, the number relationship of permanent magnet poles, the layout of Hall elements and the specific pole recognition process are determined. The MATLAB software is used to simulate the working process of the magneto electric encoder, which proves the feasibility of the absolute angle calculation scheme.
