In the two cases, because the current directions of the power terminal and the ground terminal of the hall element are changed, i.e. the voltage directions of the power terminal and the ground terminal of the hall element are changed, and a diode characteristic exists between the power terminal and the ground terminal inside the hall element, when the voltage directions of the power terminal and the ground terminal of the hall element are changed, the magnitude of the current is changed accordingly, and the potential of the power terminal and the ground terminal of the hall element is finally caused to change, the voltage between the power end and the grounding end of the Hall assembly can be obtained by detecting the potential difference between the power end and the grounding end of the Hall assembly, and when the voltage is zero, the short circuit condition of the power end and the grounding end of the Hall assembly can be judged, namely, the terminal wire welded with the power end and the grounding end of the Hall assembly is in short circuit; when the voltage is the voltage of an external power supply, the condition that the power end and the grounding end of the Hall assembly are in an open circuit state can be judged, namely the poor contact of the terminal wire welded at the power end or the grounding end of the Hall assembly is realized; by combining the diode characteristic existing between the power supply end and the grounding end in the Hall assembly, when the voltage between the power supply end and the grounding end of the Hall assembly is detected and the voltage between the grounding end and the power supply end is opposite to the actual condition, the wiring of the wiring terminal of the power supply end of the Hall assembly and the wiring terminal of the grounding end can be judged to be wrong, and the line sequence is disordered. The process of judging whether the grounding end and the signal end of the Hall assembly have welding errors or not is similar to the process.
