摘要
近年来,智能车辆已经成为各国车辆工程领域研究的热点和汽车行业增长的新动力。本文就是介绍以STC89C52为核心控制芯片,以E18-D80N为红外传感器的红外避障智能车系统。主要目的就是探究智能车辆在遇到障碍物时所应该采取的自动正确反应,从而避免事故,保证人生安全。系统通过红外传感器探测智能车周边障碍物,传感器将探测信号传送给控制芯片,控制芯片通过程序判断,向智能车驱动模块传送准确驱动型号,控制智能车运动方向与速度。同时,编码器采集智能车速度信号并传输给主控芯片,通过相应算法计算出转速后通过LED显示程序显示,给出直观数据。该系统随智能车启动同时进行,当遇到障碍物自动正确给出处理信号,保证智能车行驶安全。
In recent years, the intelligent vehicle has become the new hot spot of research in the field of power and the automotive industry countries in the growth of vehicle engineering. This paper is to introduce STC89C52 as the core control chip, the E18-D80 N infrared sensors for obstacle avoidance of intelligent car system. The main purpose is to explore the correct reaction of automatic intelligent vehicle should take in the face of obstacles, so as to avoid accidents, ensure the life safety. The smart car system through the infrared sensor to detect the surrounding obstacles, the sensor will detect the signals to control chip, control chip through a program to determine, to the smart car driving module to send accurate driver model, motion direction and speed of the smart car control. At the same time, the encoder data acquisition intelligent vehicle speed signal and transmitted to the main control chip, calculated by the corresponding algorithm to speed through the LED display program, given the visual data. The system with intelligent car starts at the same time, the obstacle automatically given signal processing, ensure the running safety of the smart car.
