Wuhan University of Technology Signal Detection

Overview

This system uses the STC89C52 microcontroller as the control core and combines the voltage boost module, motor drive module,
current detection module, AB phase encoder, ultrasonic ranging module and wireless transmission module to design and implement
a current feedback DC motor control system and complete it. Corresponding test equipment is provided. This system uses a boost circuit and
a motor drive circuit to supply power to the DC motor. Parallel resistor current measurement is used to convert the current signal into a voltage
signal and achieve current measurement through AD sampling. Use AB phase encoder to realize real-time rotation speed measurement, and use
ultrasonic wave to realize distance and speed measurement. Each measurement result is finally transmitted to the PC for display through the wireless module.
Through debugging and cascading, the basic requirements of the question are achieved. It can achieve low ripple and high efficiency of the boost module; the drive
circuit meets the power supply requirements; the monitoring current bandwidth is higher than 1KHZ, and the error is no more than 1%; it realizes the rotation speed detection,
speed and distance measurement system.
