The angular position sensor is internally composed of a mechanical rotating structure and four sine and cosine transformers, the mechanical rotating structure is coaxial with each sine and cosine transformer, and the sine and cosine rotary transformers are used for converting mechanical angle signals into electrical signals to be output. At present, an angular position sensor detection device used in the field of aviation repair mainly comprises an industrial personal computer, an adapter, a numerical multimeter, a driving servo motor, a power supply and the like. The power supply supplies power for each rotary transformer in the sensor, the drive servo motor is used for ensuring that the sensor to be detected can rotate to any angle, the digital multimeter is used for detecting output signals of the sensor, the adapter is used for conditioning drive motor control signals output by the industrial personal computer and controlling power supply signals, other parts are shelf products except the adapter in the detection device composition, the adapter needs to be designed and developed autonomously, and the development period and the cost of the detection device are increased.
For example, the detection and correction system of the magnetic resistance type angle sensor, which is disclosed in chinese patent No. 205037863, comprises a PLC, a stepping motor, a transmission shaft, an MCU, a rotary magnet, etc., wherein the stepping motor is controlled by the PLC to drive the rotary magnet to rotate to a predetermined angle, and the MCU is used to collect a rotation angle and feed the rotation angle back to the PLC.

The equipment utilizes serial port communication to realize turntable control, and adopts a PCIE acquisition board card to realize data acquisition. The method has the advantages that firstly, an adapter turntable control module needs to be manufactured, so that the development period and the development cost are increased; secondly, the PCIE board card used for collecting data can only detect voltage signals, and cannot complete signal tests such as current consumption and resistance of a product to be tested.
