Angle detection device and detection method thereof

The invention relates to the technical field of angle detection, and particularly relates to an angle detection device and a detection method thereof. According to the angle detection device, four Hall elements are fixedly arranged on a circuit board; the four Hall elements are arranged around a magnetic ring, and are located on quartering points of a same virtual circle respectively, and the circle center of the virtual circle is located on the center line of the magnetic ring, so that mechanical assembly errors existing in a signal generation part, and signal errors, caused by the fact thatthe magnetic ring and the outer circles of the Hall elements are not concentric, of the sensor can be avoided. According to the angle detection device designed by the invention scheme, a novel magnetic angle sensor which is high in resolution and high in precision and is suitable for severe working conditions can be invented. 本发明涉及角度检测技术领域，特别涉及一种角度检测装置及其检测方法，通过在电路板上固定设置四个霍尔元件，四个霍尔元件环绕磁环周围设置，四个霍尔元件分别位于同一个虚拟圆的四等分点上且虚拟圆的圆心位于
