The Design of Ultrasonic Range Finder Based on MCU
Abstract: For wireless location problem, put forward the ultrasonic and single-chip integrated scheme, presents a design of ultrasonic range finder based on the control part, system, emission part, receiving part and shows the presence of some of the problems are analyzed and treated. This paper designs the ultrasonic ranging system, it is simple, specific analysis of the design principle of the ultrasonic range finder and each part of components, with the relevant parts of the hardware circuit diagram and schematic diagram. Proved by the experiment, the system hardware and software design is reasonable, strong anti-interference ability, good real-time. After the system expansion and upgrade, it can effectively solve the car parking, building construction site and some industrial field position monitoring.
