The automobile wheel speed sensor is one of the key components of anti-lock braking system (ABS), and its performance directly determines the level of ABS performance. The output of the magnetoelectric ABS speed sensor is approximately a sinusoidal signal, and the performance of the sensor can be obtained by analyzing the amplitude, frequency and effective value of the sinusoidal signal. This work takes STM32F407 as the main control board and uses fast Fourier transform as the main tool to design a digitally controlled sinusoidal signal measurement device to measure various parameters. It has been verified by experiments that the device can accurately measure the frequency, effective value, peak value and distortion of the input signal within 5% error and restore the signal waveform. At the same time, in order to facilitate observation, this design uses the bluetooth communication module to synchronously upload the measurement data to the mobile phone.
