基于单片机的货车“死亡弯月”警示装置设计研究

Design and Research of the Warning Device of"Dead CrescentMoon"in Design and Research of the Warning Device of"Dead Moon"in Freight Car Based on Single Chip Microcomputer

本文阐述了一款由摄像头、激光发射器、语音播报装置及车载装置组成的货车“死亡弯月”警示装置的设计。该装置能在货车转弯时实时监测车辆右侧的状态变化,并且能通过语音播报装置与激光发射器对车外行人、车辆以及车内驾驶员报警。利用这种车内警示和车外警示双向提示功能,让驾驶员可以及时发现车外状况,及时做出避让,同时让行人和其他车辆快速清楚自身是否身处“死亡弯月”区域以便及时逃离危险地带。

This paper designed a warning device of"death crescent moon"for freight cars,which is composed of camera,laser transmitter,voice broadcast device and vehicle mounted device.It can monitor the status change of the right side of the vehicle in real time when the truck turns left and right,and can alarm pedestrians outside the vehicle,vehicles and drivers inside the vehicle through voice broadcast device and laser transmitter.It can also have the function of warning inside and outside the vehicle,two-way prompt,so that the driver can find out the situation outside the vehicle in time,so that pedestrians and other vehicles can quickly know whether they are in the"dead crescent",and make timely avoidance and escape from the danger zone.
