避障模塊設(shè)計(jì)是通過把左右紅外線反射式傳感器模塊的輸出端分別接到單片機(jī)的P20和P21管腳上,然后通過單片機(jī)編程,產(chǎn)生PWM控制信號,通過L298控制電機(jī)的轉(zhuǎn)速,讓小車達(dá)到前進(jìn)、左轉(zhuǎn)、右轉(zhuǎn)及停止行駛的目的。本模塊發(fā)射端采用高靈敏的HL5000型萬能電視遙控器,接收端采用接收頻率為38KHZ的萬能接收頭182,該模塊與單片機(jī)接口非常方便。迅即模塊主要由廣電反射式傳感器組成。在系統(tǒng)的設(shè)計(jì)過程中,用兩個(gè)L9110芯片來分別連接單片機(jī)和直流電機(jī)。該智能小車在貼有黑線的白紙“路面”上行駛,因此本模塊設(shè)計(jì)需要檢測鋪在行駛區(qū)的黑膠帶,包括直線行駛區(qū)和沿弧線行駛區(qū)兩個(gè)區(qū)域。通過角度傳感器[1]檢測蹺蹺板角度的變化,利用增量式pi算法[2]控制電動車尋找平衡點(diǎn),同時(shí)運(yùn)用光電傳感器檢測黑線,使電動車在行駛過程保持之先切不會脫離蹺蹺。南京航空航天大學(xué)金城學(xué)院畢業(yè)設(shè)計(jì)(論文)外文文獻(xiàn)翻譯系 部機(jī)電工程系專 業(yè)車輛工程學(xué)生姓名顧偉學(xué)號200901223指導(dǎo)教師卞利云職稱講師2013年2 月Electric intelligent car based on SCMThrough research and to realize a photoelectric sensor for sensitive ponents ,with AT89C51 as control core electric tracing of intelligent control carbonylationthe car ,the system is also including dc motor ,L9110 chips and LM324 parator etc. The design USES AT89C51 as intelligent car core controller.The system takes microcontroller as control core and realization of electric before Enter ,back ,turn left and right turn function .Through the Angle sensor detection the seesaw Angle change ,use incremental pl algorithm to control the electric car for balance ,and using photoelectric sensor detection black line ,make the electricity Actuation vehicle in the course of driving keep linear motion and don’t skip from atrium .1. Project Design Light buy a sensor ,the reality of the electric car is moving quickly degrees ,bit ,buy, transportation line shape when measured quantity of real condition ,and will be measured quantity number according to preach sent to monolithic machine into line processing, but buy single chip machine according to the measured buy root different forms of several inspection according to real now to electric actuation vehicle wisdom can control system .This kind of square case real now to electric actuation vehicle dynamic shape state into the shipment do real possession in system ,control system spirit alive ,can depend ,pure degree is high ,can full foot of each item of the stockings to bed .(1)straight epidemiological speed is tasseled straight epidemiological speed department with pulse width modulation experience .meanwhile gather speed is experience .meanwhile ,its main electrical pulse width modulation by road system type variable change device ,Jane says PWM variable change device .Adjustable speed by in the department of PWM experience .Meanwhile open shut frequency rate is high ,only on electricity barnado electricity sense of filter wave can be use to get to move very small straight pulse electric flow ,electricity flow barnado electric capacity easily even tantras, department of low speed operation flat experience .meanwhile ,adjustable speed stability van is surrounded relatively wide ,can reach 1000 left light .By on electrical flow wave shape than VM system .be in phase with flat to all electrical flow dynamic machine ,electric heat consumption and hair loss than a small
