北京理工大学珠海学院 2020 届本科生毕业设计汽车后视镜报警器汽车后视镜报警器摘 要 汽车作为工业产品在我国得到了高速的发展，人们的汽车使用量也在升高，人们把越来越多的注意力放在汽车行驶的舒适性与安全性上。汽车的总量增加，那么道路就会变得拥挤，因此驾驶员需要获取汽车后方、下方及侧方的路况信息，汽车盲区而引发的事故日益增多，汽车盲区凸显的问题也越来越严重。汽车后视镜报警器是一种采用传感器探测汽车盲区的设备，对汽车运行的安全性以及驾驶员的生命财产安全保障有着重大意义。汽车行驶过程中存在着很多盲区，A 柱盲区、B 柱盲区、后视镜盲区以及车底盲区。本设计针对汽车 A 柱、后视镜形成的视野盲区，对驾驶员对路况做出判断的难题。对盲区报警装置的组成、工作原理、电路进行设计。该装置基于 51 单片机，采用超声波模块和红外线感应模块对 A 柱、后视镜盲区范围内探测的信号进行处理，对盲区内的人或物的间隔距离进行测量，并对车内驾驶员通过 LED 灯条进行预警。关键词：汽车盲区，盲区报警，后视镜报警器1北京理工大学珠海学院 2020 届本科生毕业设计Car rearview mirror alarmAbstrsctAs an industrial product, automobiles have developed rapidly in China. The popularity of cars is increasing. People's requirements for comfort and safety have also increased. The number of cars is increasing, then the road will become congested, so drivers need to obtain information on the road conditions behind, below, and to the side of the car. Accidents caused by blind spots in cars are increasing, and the problems highlighted by blind spots in cars are becoming more and more serious. The car rearview mirror alarm is a device that uses sensors to detect blind spots in the car, which is of great significance to the safety of the car's operation and the safety of the driver's life and property.There are many blind spots in the process of car driving, A-pillar blind spot, B-pillar blind spot, rearview mirror blind spot and bottom blind spot. This design aims at the blind spo...
