超聲波測(cè)距原理超聲波發(fā)射器向某一方向發(fā)射超聲波，在發(fā)射時(shí)刻的同時(shí)開始計(jì)時(shí)，超聲波在空氣中傳播，途中碰到障礙物就立即返回來，超聲波接收器收到反射波就立即停止計(jì)時(shí)。當(dāng)它的兩極外加脈沖信號(hào)，其頻率等于壓電晶片的固有振蕩頻率時(shí)，壓電晶片將會(huì)發(fā)生共振，并帶動(dòng)共振板振動(dòng)，便產(chǎn)生超聲波。本設(shè)計(jì)屬于近距離測(cè)量，可以采用常用的壓電式超聲波換能器來實(shí)現(xiàn)觸發(fā)單元。超聲波傳感器是利用壓電效應(yīng)的原理將電能和超聲波相互轉(zhuǎn)化，即在發(fā)射超聲波的時(shí)候，將電能轉(zhuǎn)換，發(fā)射超聲波；而在收到回波的時(shí)候，則將超聲振動(dòng)轉(zhuǎn)換成電信號(hào)。其實(shí)超聲測(cè)距原理簡(jiǎn)單: 它發(fā)射超聲波并接收反射回波, 通過單片機(jī)計(jì)數(shù)器獲得兩者時(shí)間差t, 利用公式S=Ct/2計(jì)算距離, 其中S為汽車與障礙物之間的距離, C為聲波在介質(zhì)中的傳播速度。顯然，此類產(chǎn)品的研究開發(fā)具有極大的實(shí)現(xiàn)意義和廣闊的應(yīng)用前景。從經(jīng)濟(jì)性和安全性兩方面來說，中原工學(xué)院畢業(yè)設(shè)計(jì)（論文）譯文這些被動(dòng)安全措施是在事故發(fā)生時(shí)刻對(duì)車輛和人員進(jìn)行保護(hù)，有很大的局限性，因而車輛的主動(dòng)安全研究尤為重要，引出了本文研究的基于單片機(jī)的超聲波測(cè)距系統(tǒng)。同時(shí)，隨著汽車工業(yè)的飛速發(fā)展，汽車的產(chǎn)量和保有量都在急劇增加?？冃гu(píng)估機(jī)制，可以支持這種說法。雖然所有的信息，尤其是交通燈控制規(guī)則已提取國際標(biāo)準(zhǔn)和科學(xué)交通文學(xué)，專家的知識(shí)優(yōu)勢(shì)是他們最后的正確性驗(yàn)證標(biāo)準(zhǔn)。例如，假期期間的周期時(shí)間是較平日少。本次評(píng)選有助于智能系統(tǒng)，以確定下一步的階段測(cè)序。第五節(jié)從路口提取的圖像信息解釋。一些努力已制成這個(gè)通過展示和使用本體檢測(cè)交通領(lǐng)域擁塞，管理非城市道路氣象事件，駕駛阿德?！骼锵到y(tǒng)，共享和整合一個(gè)智能交通系統(tǒng)。這個(gè)領(lǐng)域的建模知識(shí)幫助交通代理和應(yīng)用有效地管理關(guān)于實(shí)時(shí)條件下的交通。本文最重要的目的之一是提出一個(gè)獨(dú)立的可重復(fù)使用的交通燈控制模塊。綠燈模擬器是一個(gè)交通模擬器，監(jiān)控交通流量統(tǒng)計(jì)，如平均等待時(shí)間，并測(cè)試不同的交通燈控制器。交通仿真有幾個(gè)不同的模型。該智能交通燈控制系統(tǒng)可以實(shí)現(xiàn)的功能有：對(duì)某市區(qū)的四個(gè)主要交通路口進(jìn)行控制：個(gè)路口有固定的工作周期，并且在道路擁擠時(shí)中控制中心能改變其周期：對(duì)路口違章的機(jī)動(dòng)車能夠即時(shí)拍照，并提取車牌號(hào)。本文介紹了一個(gè)智能交通的系統(tǒng)的設(shè)計(jì)。例如避免交通擁堵被認(rèn)為是對(duì)環(huán)境和經(jīng)濟(jì)都有利的，但改善交通流也可能導(dǎo)致需求增加。我們對(duì)自己的聚類算法模型和其它使用綠燈模擬器的系統(tǒng)做了比較。The

machine’s only realizing intellectualized administration of crossroads traffic light,use operation in controlling the vehicular traffic research has the goal to optimize transportation flow of people and the number of road users constantly increases, and resources provided by current infrastructures are limited, intelligent control of traffic will bee a very important issue in , some limitations to the usage of intelligent tra?c control jams for example is thought to be beneficial to both environment and economy, butimproved trafficflow may also lead to an increase in demand [Levinson, 2003].There are several models for traffic our research we focus on microscopicmodels that model the behavior of individual vehicles, and thereby can simulate dynamics of groups of has shown that such models yield realistic behavior[Nagel and Schreckenberg, 1992, Wahle and Schreckenberg, 2001].Cars in urban traffic can experience long travel times due to inefficient traffic light control of traffic lights using sophisticated sensors and intelligent optimizationalgorithms might therefore bevery of traffic light switching increasesroad capacity and traffic flow, and can prevent tra?c light control is aplex optimization problem and several intelligent algorithms, such as fuzzy logic, evolutionary algorithms, and reinforcement learning(RL)have already been used in attemptsto solve this paper we describe a modelbased, multiagent reinforcement learningalgorithm for controlling traffic our approach, reinforcement learning [Sutton and Barto, 1998, Kaelbling et al., 1996]with roaduserbased value functions [Wiering, 2000] is used to determine optimal decisionsfor each traffic decision is based on a cumulative vote of all road users standingfor a traffic junction, where each car votes using its estimated advantage(or gain)of settingits light to gainvalue is the difference between the total time it expects to waitduring the rest of its trip if the light for which it is currently standing is red, and if it is waiting time until cars arrive at their destination is estimated by monitoring cars flowingthrough the infrastructure and using reinforcement learning(RL) pare the performance of our modelbased RL method to that of other controllersusing the Green Light District simulator(GLD).GLD is a traffic simulator that allows usto design arbitrary infrastructures and traffic patterns, monitor traffic flow statistics such asaverage waiting times, and test different traffic light experimental resultsshow that in crowded traffic, the RL controllers outperform all other tested also test the use of the learned average waiting times for choosing routes of cars through the city(colearning), and show that by using colearning road users can avoidbottlenecks.第二篇：外文翻譯設(shè)計(jì)一個(gè)位于十字路口的智能交通燈控制系統(tǒng)摘要：本文模型使用模糊本體的交通燈控制域，并把它應(yīng)用到控制孤立十字路口。關(guān)鍵詞:模糊本體,智能代理,智能交通系統(tǒng)(ITS),交通信號(hào)燈控制(TLC),孤立的十字路口,圖像處理,人工神經(jīng)網(wǎng)絡(luò)作為城市交通增加的結(jié)果,道路網(wǎng)絡(luò)的能力有限和發(fā)展交通工具和方法的技術(shù)方面，許多實(shí)體，關(guān)系，情況和規(guī)則已經(jīng)進(jìn)入交通燈控制域和轉(zhuǎn)化成為一個(gè)知識(shí)領(lǐng)域。這些領(lǐng)域之一是智能交通系統(tǒng)。第4節(jié)介紹交通燈控制的模糊本體的建設(shè)。在此類別中的所有規(guī)則如表1所示。當(dāng)天的參數(shù)是在日歷基礎(chǔ)上基于假期和正常的一天與周期時(shí)間量的關(guān)系預(yù)定義的。評(píng)價(jià)過程的主要目的是顯示發(fā)展的本體和其相關(guān)的軟件環(huán)境的用處。邏輯交通控制滿足所有的交通燈控制的需求，并能回答的能力問題。隨著經(jīng)濟(jì)的發(fā)展與汽車科學(xué)技術(shù)的進(jìn)步，公路交通呈現(xiàn)出行駛高速化、車流密集化和駕駛員非職業(yè)化的趨勢(shì)。目前汽車安全領(lǐng)域被動(dòng)安全研究較多，主要從安全氣囊、ABS(防抱死系統(tǒng))和懸架等方面著手，以保證駕乘人員的安全。因此，大力研究開發(fā)如汽車防撞裝置等主動(dòng)式汽車輔助安全裝置，減少駕駛員的負(fù)擔(dān)和判斷錯(cuò)誤，對(duì)于提高交通安全將起到重要的作用。汽車防撞雷達(dá)之所以能實(shí)現(xiàn)防撞報(bào)警功能，主要有超聲波這把無形尺子, 它測(cè)量最近障礙物的距離, 并告訴給車主。超聲波傳感器有發(fā)送器和接收器，但一個(gè)超聲波傳感器也可具有發(fā)送和接收聲波的雙重作用。超聲波發(fā)生器可以分為兩類：一類是用電氣方式產(chǎn)生超聲波，一類是用機(jī)械方式產(chǎn)生超聲波。超聲波發(fā)生器內(nèi)部結(jié)構(gòu)，它有兩個(gè)壓電晶片和一個(gè)共振板。強(qiáng)度較強(qiáng)的脈沖會(huì)比強(qiáng)度較弱的脈沖超過界限的時(shí)間早點(diǎn)，因此我們會(huì)認(rèn)為強(qiáng)度較強(qiáng)的脈沖屬于較近的物體。IC2是帶有鎖定環(huán)的音頻譯碼集成塊LM567，內(nèi)部壓控振蕩器的中心頻率f0=1/，電容C4決定其帶寬。關(guān)外部中斷0 讀取時(shí)間值MOV R7,TH0。通過脈沖的周期設(shè)置下一個(gè)脈沖。定時(shí)中斷服務(wù)子程序完成三方向超聲波的輪流發(fā)射，外部中斷服務(wù)子程序主要完成時(shí)間值的讀取、距離計(jì)算、結(jié)果的輸出等工作。ultrasonic firing continued 200ms here:cpl 。open external interrupt
