AI Technical Summary
Existing gear sensors have excessively long initialization and adjustment times at high speeds, while existing methods are suitable for low-speed scenarios, which makes it easy for operational amplifier offset and gain adjustments to be erroneous.
By acquiring the real-time ADC value output from the ADC in the gear sensor, and combining it with the preset ADC extreme value threshold, the ADC extreme value is captured, and at least the last two ADC extreme values are captured continuously. The waveform edge, peak-to-peak value and midpoint value are obtained, and it is determined whether they are within the preset range. The gain and offset are adjusted in conjunction with the waveform edge to shorten the initialization time.
In high-speed scenarios, it can quickly obtain reliable initial adjustment results, reduce initialization time, and improve the adjustment efficiency of gear sensors at high speeds.
