AI Technical Summary
The existing gas meter sampling component has a cumbersome and error-prone process for detecting the engagement angle, resulting in low efficiency and an inability to guarantee uniform rotation, which leads to inaccurate measurements.
The gas meter sampling component uses a Hall element to sense the magnetic field strength, combined with a stepper motor to drive a reluctance wheel to rotate at a constant speed, and the processor automatically calculates the engagement angle to eliminate errors caused by changes in rotation speed.
It improves the calibration efficiency of the sampling components and the accuracy of the suction angle measurement, reduces human calculation and oscilloscope sampling errors, and realizes automated testing.
