【文章內(nèi)容簡介】 rtain technological means to achieve them. Based on the current traffic control based on indepth analysis to, using the sensor detection technology, wireless transmission technology, realtime adjustment of the realization of the intelligent control technology, the sensor detection, realtime adjustment of traffic time algorithm bined with single chip microputer, is proposed based on single chip microputer intelligent traffic control system design.8051 single chip wireless intelligent traffic light control system controlled by 8051, traffic light display, LED countdown. Traffic detection and adjustment, such as wireless transmission module. In addition to the basic function of traffic light also has the traffic detection system, wireless transmission in order to achieve the purpose of the intelligent traffic control. System by the number of the test vehicle, by wireless transmission module NRF24L01 sent to the host, the host through the intelligent control algorithm lane in the direction of the change of green light time to realize intelligent control. Theory to prove the system is simple, economic and effective traffic, improve the traffic capacity of the traffic intersection.This design mainly do the following several aspects work: one part, display, sensors, wireless transmission welding part of the hardware. Second, traffic lights of conventional control method and the realization of the sensor count. Third, the realization of the wireless data transmission.【Keywords】The traffic light 8051Single chip microputer Wireless transmission Intelligent control sensors 一、緒論 概述信號燈的出現(xiàn)使得交通得以有效管制，對于疏導(dǎo)交通流量、提高交通道路通行能力減少交通事故有明顯效果。但是，隨著城市機(jī)動車增長速度加快，我國的城市道路密度和面積率偏低。交通管理水平還欠發(fā)展。本設(shè)計(jì)就這一現(xiàn)象就行分析設(shè)計(jì)出基于51單片機(jī)的無線智能交通燈控制系統(tǒng)。在這個系統(tǒng)中，我們將采用車流量來控制紅綠燈的時間并以此來達(dá)到舒緩交通壓力的目的。本設(shè)計(jì)主要做了如下幾個方面的工作：確定系統(tǒng)交通的總體設(shè)計(jì)，包括，十字路口具體的進(jìn)行方案設(shè)計(jì)以及系統(tǒng)應(yīng)用有的各項(xiàng)功能。在這里，本設(shè)計(jì)除了有信號燈狀態(tài)孔子能實(shí)現(xiàn)基本的交通功能，還增加了倒計(jì)時顯示提示?；趯?shí)際情況又增加了對車流量進(jìn)行檢測的功能，無線通信的功能。進(jìn)行顯示電路，各個無線結(jié)點(diǎn)的硬件電路等的設(shè)計(jì)，對各器件的選擇，大體分配各個期間及模塊的基本功能要求。進(jìn)行軟件系統(tǒng)的設(shè)計(jì)，對于本系統(tǒng)，我們采用c語言編寫。對于無線模塊的通信的軟件的編寫我們做了充分研究，總體上完成了軟件的編寫。設(shè)計(jì)任務(wù)運(yùn)用所學(xué)傳感器技術(shù)、計(jì)算機(jī)網(wǎng)絡(luò)和單片機(jī)原理等方面的知識，設(shè)計(jì)于無線傳感器網(wǎng)絡(luò)的智能交通紅綠燈控制系統(tǒng)，完成無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)設(shè)計(jì)以及基于單片機(jī)的交通紅綠燈系統(tǒng)軟硬件設(shè)計(jì)等工作。具體任務(wù)如下：設(shè)計(jì)要求（1）繪出無線傳感器網(wǎng)絡(luò)紅綠燈控制的原理圖（節(jié)點(diǎn)布設(shè)及系統(tǒng)搭建方案）。（2）設(shè)計(jì)無線傳感器網(wǎng)絡(luò)節(jié)點(diǎn)，實(shí)現(xiàn)對車輛的計(jì)數(shù)功能。（3）設(shè)計(jì)基于單片機(jī)的紅綠燈控制方案，實(shí)現(xiàn)依賴于車流量的智能交通控
