基于单片机的车载智能防撞系统设计

Design of Vehicle Intelligent Collision Avoidance System Based on Microcontroller

近年来,随着我国汽车保有量的增加,道路交通安全愈发受到社会关注。目前,在交通事故中,不乏因后车紧急超车而引起的事故;在倒车过程中,驾驶员无法及时发现后方车辆或障碍物,可能导致车辆损坏和其他经济损失。为了应对这些潜在的交通安全风险,以51单片机作为主控芯片,设计了一款车载智能防撞系统。使用低成本的HC-SR04超声波模块,实现了精准且高效的距离测量。当距离达到阈值时,蜂鸣器报警,以提醒驾驶员及时作出反应。该设计方案旨在提供全方位的防范提醒,有效保障驾乘人员的人身和财产安全。

In recent years,with the increase in vehicle ownership in our country,road traffic safety has attracted more and more attention from society.Currently,traffic accidents often occur due to rear-end collisions caused by sudden tailgating.During the reversing process,the driver cannot detect the vehicles or obstacles behind in time,which may cause vehicle damage and other economic losses.To solve this problem,a car-mounted intelligent anti-collision system is designed using the 51 microcomputer as the main control chip.Using the low-cost HC-SR04 ultrasonic ranging module for distance measurement,efficient and accurate distance measurement is achieved.The design scheme aims to provide com-prehensive prevention reminders to effectively protect the personal and property safety of drivers and passengers.
