【正文】 xx 大學(xué)學(xué)士學(xué)位論文 I 基于 DSP 的交通燈控制系統(tǒng)的 設(shè) 計(jì) 摘要 當(dāng)今時(shí)代是一個(gè)自動(dòng)化時(shí)代，隨著汽車業(yè)與交通運(yùn)輸事業(yè)的快速發(fā)展，大中城市的道路交通的控制也問(wèn)題日益突出，然而增加道路以及對(duì)車輛運(yùn)行的限制已不是解決該問(wèn)題最經(jīng)濟(jì)有效的辦法。如何在現(xiàn)有道路交通設(shè)施的條件下更好的解決交通問(wèn)題才是我們目前需要考慮的。 道路交通燈的控制和很多行業(yè)的設(shè)備都與計(jì)算機(jī)密切相關(guān)。因此，一個(gè)好的交道路通燈控制系統(tǒng)，將會(huì)給道路擁擠、車輛違章控制等方面給予技術(shù)革新。隨著大規(guī)模集成電路及計(jì)算機(jī)技術(shù)的迅速發(fā)展，以及人工智能在控制技術(shù)方面的廣泛深入運(yùn)用，智能交通燈控 制設(shè)備有了很大的發(fā)展，是目前交通燈控制系統(tǒng)發(fā)展的主流方向。 本文介紹了一個(gè)智能交通燈控制系統(tǒng)的設(shè)計(jì)。該智能交通燈控制系統(tǒng)可以實(shí)現(xiàn)的功能 主要 有：對(duì)某市區(qū)的主要交通路口進(jìn)行控制；使各路口有固定的工作周期，并且在道路擁擠時(shí)中控中心能夠改變交通燈的變換周期。 該設(shè)計(jì)以 DSP TMS320VC5509 為路口控制核心 ，以單個(gè)路口控制為研究對(duì)象，與 PC 機(jī)之間的的通信采用 MAX232 進(jìn)行轉(zhuǎn)換。 作為整個(gè)交通網(wǎng)絡(luò)最小研究單元的單個(gè)交叉路口，對(duì) 于單個(gè)路口 的控制方法的研究是整個(gè)交通 燈 控制網(wǎng)路的 研究 基礎(chǔ)， 具有非常重要的意義。 關(guān)鍵 詞 交通燈 ； DSP； CPLD xx 大學(xué)學(xué)士學(xué)位論文 II Design of Integrated Control System of Lights Based on DSP Abstract The age is an automatic age nowadays and With the rapid development of automobile and traffic management, the heavy traffic problem in the big sities bees more and more serious, and the solution by increasing new road and constraining the vehicle is not the most economical and effective measures. How to solve traffic problems in existing condition is worth considering. Transportation light control and the devices in many professions is closely related with , a good transportation light control system, will give technique innovation hustle for the road, the illegal control with the technical quick development of the large scale integration,the puter techknowledge, and the wide use of the artificial intelligence in the control system, the intelligence control equipment have a very big development, which is the essential direction in the modern science and technology development. This article introduces a design of an intelligence transportation light intelligence39。s transportation light control system can carry out of these functions:Carry on the main transportation street corners of some downtown。Each street corner contain a fixed work period, and control centercan change its period when the traffic is heavy. The design uses the intersection control TMS320VC5509 by DSP core, with a single intersection control as the research object, and the munications between PCs by using MAX232 conversion. As the minimum single intersection in the traffic work research unit， a single intersection control method is the traffic control work research foundation,which has the extremely vital significance.
