河南科技学院 本科毕业论文( 设计) 论文题目: 客车超载控制系统设计学生姓名: 张冠华所在院系: 机电学院所学专业: 机械设计制造及其自动化导师姓名: 孔晓红 张素君完成时间: 5 月 20 日摘 要针对当前客车超载不断引发重大事故, 设计了一种客车超载监控系统。本设计以AT89c51单片机为核心。经过红外线发射接收装置对客车的载客人数进行检测, 然后由单片机对检测到的数据进行分析处理, 同时检测到的结果会由LED显示出来, 假如客车超载, 扬声器先进行报警, 而后由继电器切断汽车的打火装置, 从而最终实现对超载情况进行相关控制。关键词: 客车超载控制系统; 红外线传感器; 单片机AbsractAccording to the overloading of the current bus causing the major accident,the paper designs a kind of monitoring system about the bus overloading.The designing is at the core of AT8951 single-chip.This designing detects the number of passengers on bus by Fired infra-red receiver,and then it analyses detected data through the single-chip,as the same time LED will displayed detected results.If the bus overloads,the speaker will alarms,and then the relay will cuts off the brand devices on bus,finally it achieves the related control of overloading.Key words : Carriage overload monitor system ; Inf rared sensor ; MCU目 录1 绪论..............................................................22 系统的整体结构....................................................22.1 系统的组成..................................................22.2 系统的原理..................................................33 系统硬件的设计....................................................33.1 系统硬件总体的组成..........................................33.2 检测模块电路................................................43.3 单片机模块电路..............................................73.4 控制模块电路...............................................103.4.1 数码管显示电路设计...................................103.4.2 报警电路设计...........................
