【正文】 秒,以便讓停車線以外的車輛停止運行,因為主干道車流量較多,所以主干道放行時間長。之后就是緊張的電路連接以及在連接的過程中進行電路的調(diào)試,期間還進行了部分方案的改動及改進,實現(xiàn)了本次交通燈設(shè)計的主要任務(wù)和具體要求。然后通過各種途徑的查閱資料,并已學(xué)過的數(shù)字電路的知識從所給的元件中選擇出符合我們構(gòu)思的電路原理的元件,最后考慮到電路的穩(wěn)定性,可控性以及電路簡單與否等因素,在交通燈基本功實現(xiàn)的基礎(chǔ)上考慮實現(xiàn)其擴展功能,即夜間模式。本次實訓(xùn)設(shè)計是根據(jù)對邏輯功能的要求及對所學(xué)的電子技術(shù)基本理論知識的綜合運用進行電路的獨立設(shè)計,仿真,實驗,調(diào)試以及寫出實訓(xùn)論文。 自從交通燈誕生以來,其內(nèi)部的電路控制系統(tǒng)就不斷的被改進,設(shè)計方法也開始多種多樣,從而使交通燈顯得更加智能化、科學(xué)化、簡便化。交通信號燈常用與交叉路口,其中紅燈亮表示道路禁止通行;黃燈亮具有警示交通燈將要轉(zhuǎn)變顏色的警示作用;綠燈亮表示該道路允許通行。 關(guān)鍵詞:交通燈,秒脈沖發(fā)生器,主控器,計數(shù)器,譯碼電路 The design of trafficlight Author:qinwurina Tutor:Baodujiya AbstractTraffic lights and intersection, used to control the flow of cars, improving the intersection vehicle traffic capacity, reduce the number of traffic accidents. With traffic lights safety travel has a great deal of security of people. This design through the use of traffic light control circuit design of digital circuits, make digital signal control intersection traffic light control circuit of two groups of red, yellow, and green traffic lights state transition method, manding various vehicles and pedestrians safe passage, implementation of traffic management automation. Mainly by the second pulse generator, timers, controllers, display decoding circuit and night consisting of yellow lights flashing mode. Second pulse generator by NE555 pulse, timer is implemented by 74LS160, the controller is posed of 74LS153 and 74LS74, decoding circuit using 74LS48 and sevensegment digital tube display. This experiment is designed to develop the capacity of digital circuits, design method of mastering traffic light control circuit.
