基于单片机的自动车库门设计

An Automatic Garage Door Design Based on the Single Chip Microcomputer

本文介绍了运用ATMEL公司生产的51内核单片机与对射式红外传感器,通过红外传感以及MATLAB程序实现车辆识别,自动开启车库门以及自动报警等功能。该系统主要由AT89C52单片机主控系统、对射式光电开关和车牌识别系统构成,通过传感器实现车库门开关的自动化。首先扫描是否有车辆停在车库门口准备在车库内停车,是否为系统内预存的车牌号相符的车辆,是则自动开启车库门,开启后自动延时关闭,如果是陌生车辆号牌,则自动启动警报,实现车库门开启与关闭的自动化。

This paper introduced using the 51 kernel single-chip computer produced by ATMEL company and correlation type infrared sensor,automatically recognizing the vehicle identification and opening the garage door automatically and alarm automatically through the infrared sensor and MATLAB. The system was mainly composed by AT89C52 single chip microcomputer control system, correlation photoelectric switch and the license plate recognition system. It realized the opening and closing of the garage door automatically through the sensor. Firstly it scanned whether there was a vehicle parked in the garage door, and ready to park the garage, whether the images of vehicles was stored in the system, if it was, then opened the garage door automatically and shut down after delay. If it was the strange plate, then began to alarm. The system realized the opening and closing of the garage door automatically.
