The car attendant privatization tide, causing a traffic load increased, thus worsening traffic problems. Traffic congestion, resulting in a variety of frequent traffic accidents. Vehicle exhaust emissions, but also pollutes the environment. The existing transportation system is not suitable to solve the existing traffic problems, this intelligent transportation system came into being. In order to achieve the Intelligent Transport System, mitigation of local street traffic jams and other problems, and improve the existing traffic light control system, design a new traffic signal control system. The control system consists of traffic control systems, vehicle monitoring system, alarm system, and other ponents. Control system using fuzzy control technology, selfadaptive regulation of traffic. The monitoring system uses traffic control and identification technology, which can effectively detect passing vehicles. The alarm system uses a finite state machine, automatic alarm on the part of vehicles violating traffic rules and can be manually forced into the incident handling state to suspend road traffic. Altera Corporation Cyclone V the series 28nmFPGA chip, and Ti lowpower MSP430F5XX Series 16 MCU chip used in the desi gn due to the traffic signal controller in the power control performance. In addition to ease of installation, little damage on the road unattended, selfadaptive to ease traffic, monitoring, accurate judgment, etc., in line with the requirements of the 21st century intelligent transportation. Key words： intelligent transportation。 由于該交通信號(hào)燈控制器在設(shè)計(jì)中采用 Altera公司 Cyclone V系列 28nmFPGA芯片，及 Ti公司低功耗 MSP430F5XX系列 16位 MCU芯片，因此在功耗控制方面性能優(yōu)異。監(jiān)控系統(tǒng)采用車流量自動(dòng)監(jiān)控及識(shí)別技術(shù)，可有效檢測(cè)過往車輛。該控制系統(tǒng)由交通控制系統(tǒng)，車輛監(jiān)控系統(tǒng)，自動(dòng)報(bào)警系統(tǒng)，等部分組成。此時(shí)原有的交通體系已不適合解決現(xiàn)有的交通問題，至此智能交通體系應(yīng)運(yùn)而生。交通的擁堵，導(dǎo)致各種交通事故頻發(fā)。 佳木斯大學(xué)畢業(yè)論文 交通信號(hào)燈控制器設(shè)計(jì) 學(xué) 院 信息電子技術(shù) 專 業(yè) 通信工程 佳 木 斯 大 學(xué) 2020 年 6 月 8 日 佳木斯大學(xué)學(xué)士學(xué)位論文 i 佳木斯大學(xué)信息電子技術(shù)學(xué)院 摘 要 隨著汽車工業(yè)的發(fā)展，汽車的產(chǎn)量逐年提高，汽車的造價(jià)也越來越低，因此擁有一輛汽車不再是夢(mèng)想。隨之而來的汽車私有化大潮，引起了交通負(fù)荷加重，交通問題也因此日趨嚴(yán)重。汽車尾氣的排放，也污染了環(huán)境。 為了實(shí)現(xiàn)交通系統(tǒng)的智能 化，緩解局部街道車輛擁堵等問題，對(duì)原有交通燈控制系統(tǒng)進(jìn)行改進(jìn)，設(shè)計(jì)了一種新型交通信號(hào)燈控制系統(tǒng)?？刂葡到y(tǒng)采用模糊控制技術(shù)，可對(duì)交通進(jìn)行自適應(yīng)性調(diào)節(jié)。報(bào)警系統(tǒng)采用有限狀態(tài)機(jī)技術(shù)，對(duì)一部分違反交通規(guī)則的車輛進(jìn)行自動(dòng)報(bào)警并可以手動(dòng)強(qiáng)制進(jìn)入突發(fā)事件處理狀態(tài)暫停路面交通。除此之外還具有安裝方便，對(duì)路面破壞小，可實(shí)現(xiàn)無人值守，對(duì)交通進(jìn)行自適應(yīng)性疏導(dǎo)，監(jiān)控判斷精確等優(yōu)點(diǎn)，符合 21世紀(jì)對(duì)交通智能化的要求。 fuzzy control。 V—FPGA......................................................................... 17 IA4432—無線通信 ....................................................................................... 18 佳木斯大學(xué)學(xué)士學(xué)位論文 II 佳木斯大學(xué)信息電子技術(shù)學(xué)院 HMC5843—3 軸數(shù)字羅盤 ........................................................................... 19 TRF7970A— 射頻識(shí)別 ................................................................................. 20 系統(tǒng)各功能模塊硬件設(shè)計(jì) .................................................................................... 21 主控制器電路實(shí)現(xiàn) ....................................................................................... 21 交通信號(hào)燈控制電路實(shí)現(xiàn) .......................................................................... 22 傳感器控制電路實(shí)現(xiàn) ................................................................................... 24 第 5 章 交通信號(hào)燈控制器軟件實(shí)現(xiàn) ................................................................................. 28 軟件整體設(shè)計(jì)思路 ................................................................................................. 28 算法與程序設(shè)計(jì)流程圖 ......................................................................................... 28 主控制器程序設(shè)計(jì) ....................................................................................... 28 傳感器，交通信號(hào)燈控制程序設(shè)計(jì) ......................................................... 34 第 6 章 總結(jié)與收獲 ............
