[0002] The magnetic ring encoder is a sensing device widely used in industrial automation, machinery manufacturing, aerospace and other fields. It is used to detect the angle and position of rotating objects. Its high precision and high reliability make it indispensable in applications that require precise position control and measurement. However, the magnetic ring encoder needs to be strictly tested before leaving the factory and during use to ensure that its performance meets the requirements. This places high demands on the detection equipment, requiring it to have high precision, stability and ease of operation. When the existing magnetic ring encoder detection equipment detects the magnetic ring encoder, the equipment structure is simple and it is difficult to provide high-precision detection results, resulting in large errors in the encoder detection process, cumbersome manual operation, and easy to be affected by human factors. The detection results are inconsistent and unreliable.
