【摘要】：摘要：隨著國(guó)民經(jīng)濟(jì)的快速發(fā)展,城市基礎(chǔ)設(shè)施建設(shè)越來(lái)越多,我國(guó)機(jī)動(dòng)車保有量飛速增長(zhǎng),城市交通擁堵問題越來(lái)越嚴(yán)重。因此研究適合我國(guó)國(guó)情的安全、快捷、高效、現(xiàn)代化的交通信號(hào)控制系統(tǒng)是解決交通問題的有效方案之一。另外,隨著可編程邏輯技術(shù)的不斷進(jìn)步和創(chuàng)新,FPGA (Field Programmable Gate Array)已被廣泛應(yīng)用于數(shù)字系統(tǒng)的設(shè)計(jì)中。論文對(duì)基于FPGA的交通信號(hào)控制器進(jìn)行研究。 論文以交通信號(hào)控制理論為出發(fā)點(diǎn),研究了一個(gè)周期內(nèi)的多種信號(hào)相位變換模式,在傳統(tǒng)的定時(shí)控制、分時(shí)段控制和智能控制這三種控制方案的基礎(chǔ)上進(jìn)行優(yōu)化處理,并設(shè)計(jì)了多模式選擇、時(shí)間可調(diào)、多時(shí)段劃分、不定相序的信號(hào)控制方案；然后以CycloneⅡ FPGA芯片為核心,以EPCS16作為配置芯片,通過(guò)擴(kuò)展存儲(chǔ)器電路、LED和七段數(shù)碼管顯示電路等,完成了基于FPGA的交通信號(hào)控制器的專用芯片設(shè)計(jì)；最后利用Verilog HDL (HDL:Hardware Discription Language)硬件描述語(yǔ)言對(duì)交通信號(hào)各種控制方案進(jìn)行分模塊設(shè)計(jì),并在Quartus Ⅱ開發(fā)平臺(tái)上進(jìn)行編譯、仿真,最后下載到FPGA芯片上,結(jié)果表明控制系統(tǒng)能夠自動(dòng)實(shí)現(xiàn)交通信號(hào)控制器的燈色變換及倒計(jì)時(shí)顯示。 基于FPGA的交通信號(hào)控制器具有電路簡(jiǎn)單、實(shí)時(shí)快速擦寫、運(yùn)算速度快、故障率低、可靠性高,而且體積小等特點(diǎn)。系統(tǒng)通過(guò)功能擴(kuò)展、接口擴(kuò)展可同時(shí)控制多個(gè)路口的紅綠燈變換,可根據(jù)需要實(shí)現(xiàn)實(shí)時(shí)、快速擦寫應(yīng)用程序的功能。
[Abstract]:Abstract: with the rapid development of the national economy, more and more urban infrastructure construction, the number of motor vehicles in China has increased rapidly, urban traffic congestion is becoming more and more serious.Therefore, it is one of the effective solutions to solve the traffic problem to study the safe, fast, efficient and modern traffic signal control system which is suitable for the situation of our country.In this paper, the traffic signal controller based on FPGA is studied.Based on the theory of traffic signal control, this paper studies a variety of signal phase transformation modes in a single cycle, and optimizes processing on the basis of three control schemes: traditional timing control, time-divided control and intelligent control.The signal control scheme of multi-mode selection, time adjustable, multi-time division and unsteady phase sequence is designed, and then Cyclone 鈪，
