【摘要】：隨著城市建設(shè)步伐的不斷加快，地鐵以及一些路政建設(shè)造成了許許多多個(gè)臨時(shí)路口，這催生了一個(gè)亟待解決的需求：無線智能交通燈。本文主要對(duì)此進(jìn)行了設(shè)計(jì)和研究。 本文首先對(duì)智能交通燈的研究現(xiàn)狀進(jìn)行綜述，由此闡明其在現(xiàn)代交通控制領(lǐng)域的重要地位，進(jìn)而提出了以單片機(jī)作為控制器的光伏無線智能交通燈的設(shè)計(jì)思想。為了更好的闡釋本設(shè)計(jì)，本文對(duì)交通信號(hào)燈相關(guān)的研究背景和基礎(chǔ)知識(shí)進(jìn)行了相應(yīng)的介紹。在此基礎(chǔ)上設(shè)計(jì)的智能交通燈包括以下功能： 1、GPRS通信功能；使用AT指令控制GPRS模塊與上位機(jī)建立數(shù)據(jù)連接并完成數(shù)據(jù)傳輸。 2、車流量預(yù)測(cè)和動(dòng)態(tài)時(shí)間調(diào)整功能；在比較分析幾種車流量預(yù)測(cè)方法的基礎(chǔ)上對(duì)其中一種方法進(jìn)行了改進(jìn)，使其對(duì)車流量的預(yù)測(cè)具有更強(qiáng)的針對(duì)性。 3、人機(jī)交互功能；給系統(tǒng)制定了更人性化的應(yīng)用平臺(tái)，使人們能夠更直觀，更方便的了解交通燈運(yùn)行的狀態(tài)及路口狀況。 另外，本文還對(duì)系統(tǒng)包含的一些配套硬件設(shè)備進(jìn)行了介紹和設(shè)計(jì)，包括溫度傳感器、LED交通燈驅(qū)動(dòng)電路、車流量檢測(cè)電路、光伏電池等。 在本文的最后，完成了對(duì)系統(tǒng)的測(cè)試，結(jié)果證明系統(tǒng)可以完成穩(wěn)定的數(shù)據(jù)傳輸，，預(yù)測(cè)結(jié)果準(zhǔn)確，控制合理。
[Abstract]:As the pace of urban construction continues to accelerate, subway and some road construction have created many temporary intersections, which has given birth to an urgent need: wireless intelligent traffic lights.This article mainly carries on the design and the research to this.In this paper, the research status of intelligent traffic lights is summarized, and the important position of intelligent traffic lights in the field of modern traffic control is expounded, and then the design idea of photovoltaic wireless intelligent traffic lights with single chip microcomputer as controller is put forward.In order to better explain the design, this paper introduces the background and basic knowledge of traffic lights.The intelligent traffic lights designed on this basis include the following functions:Using AT command to control GPRS module to establish data connection and complete data transmission.2. The function of traffic flow prediction and dynamic time adjustment, one of which is improved on the basis of comparing and analyzing several methods of traffic flow prediction, which makes the forecast of traffic flow more pertinence.3. The human-computer interaction function, to make the system more humanized application platform, so that people can be more intuitive, more convenient to understand the state of traffic lights and intersection status.In addition, this paper also introduces and designs some supporting hardware devices, including temperature sensor LED traffic light driving circuit, traffic flow detection circuit, photovoltaic cells and so on.At the end of this paper, the system is tested, and the results show that the system can achieve stable data transmission, accurate prediction results and reasonable control.
