Vehicle back up alarm design

Qi Zhou, University of Wyoming

Oral and Poster Presentation

Description

In recent years roads become more crowded, and back up a car becomes particularly inconvenient. Also there will be blind spots when people are backing up cars, sometimes people hit the car somewhere accidentally, and there would be a lot of cost for repair cars. This is the reason I wanted to design this vehicle back up alarm. This design uses ultrasonic ranging, safety assist device can be used as car backing up, inform the driver to show obstacle around the car with the sound and LED will display how far to the obstacle, also it can record personal voice to play the distance. It not only alleviated the hassle of having to repeatedly looking around, but also helps to eliminate the issue of blind spots and limited vision, improving the driver's safety when backing up. The design of hardware mainly by single-chip microcomputer control circuit, ultrasound circuit, ultrasonic receiving circuit, record voice circuit, digital distance display, the temperature display circuit and alarm circuit composition, and the software of mainly by the main program, ultrasound receiving interruption program, distance subroutines and display subroutines components, display temperature and distance, record voice.
