A rapid and automated testing system design for angular sensors

This paper addresses the issues of low automation level, slow testing speed, low testing accuracy, and significant influence of human factors on the measurement results in the original angle sensor testing system. A new design approach for an angle sensor rapid automatic testing system is proposed, which uses the 8098 microcontroller as the control core of the testing system. It utilizes a stepper motor, a fixed system, an angle sensor wind vane rotation driving system, and an automatic inclination meter to set and measure the rotation angle of the angle sensor wind vane. The system automatically measures the heating current of the angle sensor through a high-precision current measurement circuit and automatically measures the output parameters of the angle sensor through a high-precision resistance measurement circuit. It also automatically displays the measurement results and judges whether the results are qualified. The practical application has verified that the angle sensor rapid automatic testing system proposed in this paper has a fast testing speed and high testing accuracy, which meets the testing speed and accuracy requirements for the regular inspection of angle sensors by the aviation troops.
