To ensure the effective safety traffic, except for a series of traffic rules, still must through certain technological means to achieve. Based on analysis of traffic control, based on realtime detection sensor, adjust the implementation technology of intelligent control, realtime monitoring, sensor adjust vehicles time algorithm and singlechip microputer control function is proposed, which bines the traffic control system based on single chip design scheme. The 8051 microcontroller control system consists of the traffic lights display, 8051 monolithic integrated circuits, and LED the countdown, violate passes detection, emergency treatment, the blind prompt, the watchdog as modules. In addition to the basic traffic function outside, still have the blind tone, can pass the countdown display,car that forced through traffic, transportation and processing abnormal discriminant functions. Theory shows that the system can simple, economic and effective relieves traffic,improve the crossroads capacity. This design mainly do the following aspects: one is the work of the traffic control system design, including the crossroads, specific design and system should be restricted with each function, two is that the sensor, the hardware circuit design of the circuit and the basic function and requirement: Three is software system design, this system for monolithic assembly language, overall finished on the writing of the Software. Keywords: an illegal detection, countdown,blind tone 3 東 華 理 工 大 學(xué) 畢 業(yè) 設(shè) 計(jì) （ 論 文 ） 目錄 目錄 緒論 .................................................................................................................................................. 5 選 題 背 景 與 意義 ....................................................................................................................... 5 國 內(nèi) 外 交 通 燈 系 統(tǒng) 研 究 現(xiàn)狀 ................................................................................................... 6 本 次 設(shè) 計(jì) 的 優(yōu) 缺點(diǎn) ................................................................................................................... 7 第一章 系 統(tǒng) 總 體 設(shè)計(jì) ..................................................................................................................... 8 系 統(tǒng) 總 體 設(shè) 計(jì) 思路 ............................................................................................................ 8 系 統(tǒng) 設(shè) 計(jì) 方 案 論證 ........................................................................................................... 8 顯示界面方案 ........................................................................................................ 8 輸入方案 ................................................................................................................ 9 看 門 狗 保 護(hù) 方案 .................................................................................................... 9 系統(tǒng)方案設(shè)計(jì) ....................................................................................................... 9 第二章 系 統(tǒng) 硬 件 電 路 的 設(shè)計(jì) ....................................................................................................... 11 系 統(tǒng) 硬 件 總 電 路 構(gòu) 成 及 原理 .......................................................................................... 11 系 統(tǒng) 硬 件 電 路 構(gòu)成 ................................................................
