Design and implementation of labview-based upper computer for car collision avoidance system

Abstract

The driver has to face many uncontrollable factors in the process of driving, which can lead to traffic accidents if he is not careful. LabVIEW, a graphical programming software, is used to design a distance monitoring system that monitors the distance travelled by an intelligent vehicle in real time, displays it dynamically and enables human-machine interaction. The serial communication part of the system is designed through the VISA toolkit in LabVIEW. It receives the distance measurement information from the lower computer system through the serial port, so that the upper computer system can judge the vehicles, pedestrians and obstacles around the driver in real time, monitor the traffic condition around the road in real time, display it dynamically and give safety tips when it is lower than the safe distance, thus helping the driver to make a safe distance judgment in time. This helps the driver to make timely judgements on the safe distance so that he can be prepared to brake and avoid traffci accidents.
