基于ATmega128单片机的非机动车电子警示闸设计

Design of Electronic Warning Gate for Non-motor Vehicles Based on ATmega128 Single-Chip Computer

非机动车体积小,自由度高,管理困难,容易引发交通事故;路口处非机动车大量汇集,随意越线乱停,严重危害道路安全。针对非机动车在路口越线的问题,本文设计了一种基于ATmega128单片机的红外检测闸门。这种电子闸门依靠红外线来检测非机动车的位置,能够自动判断非机动车是否越线,管理非机动车。红灯时,若有超线的非机动车,则会给予警示对其提醒,以达到规范行为、保障安全的目的。整个设计由单片机最小系统、红外线发射系统、接收系统、人体检测系统和警示系统组成。设计人员按照电路要求将电子闸门各部分焊接组装起来,然后进行模拟测试,验证了该设计的可行性和准确性。

Non-motor vehicles are small in size,high in freedom,difficult to manage,and easy to cause traffic acci⁃dents;a large number of non-motorized vehicles gather at intersections,crossing the line at will and stopping at will,which seriously endangers road safety.Aiming at the problem of non-motor vehicles crossing lanes at intersections,this paper designed an infrared detection gate based on ATmega128 microcontroller.This kind of electronic gate re⁃lies on infrared to detect the position of non-motorized vehicles,can automatically determine whether non-motorized vehicles have crossed the line,and manage non-motorized vehicles.At the red light,if there is a non-motorized vehi⁃cle over the line,a warning will be given to remind it to achieve the purpose of standardizing behavior and ensuring safety.The whole design consists of the smallest single-chip microcomputer system,infrared emission system,receiv⁃ing system,human body detection system and warning system.The designer welded and assembled each part of the electronic gate in accordance with the circuit requirements,and then conducted a simulation test to verify the feasibil⁃ity and accuracy of the design.
