摘　　要：霍尔元件是一种对磁场敏感的传感器件,具有防烟尘干扰、抗振动和成本相对低廉等优点;利用线性霍尔元件作为检测,采用微机细分方式,设计了一种可从0°到大于360°范围内角度进行非接触测量的系统,给出了角度测量的原理、电路的构成及设计方法,实验表明,该系统测量精度达到设计要求,可广泛应用于工程测量领域。The hall component is sensitive to any magnetic field. It has advantages such as defending smoke, dust interference,anti-vibration and using of its linearity in measure. Its cost is relatively cheap. With the manner of single-chip microprocessor interpolation, we designed a non-contacted system that can measure angle from 0 to more than 360. We also give the principle of angle measure, constitute of electric circuit and a design method. The diagrams from experiments express that the system accuracy attains to the design request. This non-contacted system can he applied to engineering for angle measurement.
