FPGA-based ultrasonic distance measurement experiment design

Aiming at the current problem of monolithic modular teaching in the experimental teaching of electronics, this study systematically reconstructs the original experimental course system, taking the circuit comprehensive design experiment as the carrier, and upgrading the traditional discrete modular experiments into system-level experimental projects for engineering practice. The experimental design takes the ultrasonic distance measuring system as a typical application scenario, integrates the cutting-edge technologies in the field of electronics, and guides students to complete the complete engineering closed loop from theoretical analysis, program design to system realization through the integration of multidisciplinary knowledge (e.g., analog circuits, digital signal processing, and sensor technology) and teamwork practice. The reform program breaks through the fragmented teaching mode of traditional experiments, significantly improves students' independent inquiry ability, innovative thinking and teamwork consciousness, while strengthening their core knowledge of modular system design methodology, and constructs a perfect indicator-based evaluation system, which provides an effective path to cultivate composite talents adapted to the needs of the new generation of electronic system design.
