微機(jī)原理課程設(shè)計(jì)--交通燈控制系統(tǒng)設(shè)計(jì)-全文預(yù)覽
【正文】 紅、黃、綠三色信號(hào)燈即以一個(gè)完整的指揮信號(hào)家族，遍及全世界陸、海、空交通領(lǐng)域了。s concern more and more. The coordination of the person ,car , the road threes relation, have bee one of the important problems that the transportation management section demand resolve. The city transportation control system is the calculator that used for the city transportation data monitor. The transportation signal beacon control and transportation to appease prehensive management system, it is in the modern city transportation supervision conductor system to constitute part most importantly. Carry out the control method of the street corner transportation light system a lot of, can carry out with the standard logic spare part. 2Programmable preface controller PLC, single slice machine etc. Carries out the influence that the electric circuit wants to be subjected to the logic spare part, such as door, electric circuit to a large extent etc. with the standard logic spare part among them, adjust to try a work extremely not easy, and writer to single slice the luck use is not very either to acquaint with to the design development of carry on the system, therefore, the end writer chooses to use programmable controller PLC to carry out the design of the system function, pletion originally time the lesson establish of topic.Keywords: The PLC transportation light procedure report design.3目 錄前言 ......................................................................11 交通信號(hào)燈的設(shè)計(jì)目的以及要求 ...........................................12 交通信號(hào)燈基本原理及設(shè)計(jì)方法 ...........................................23 主控制器 ...............................................................4 74LS90引腳排列圖與邏輯圖 .............................................4 74LS90的功能表及引腳功能 .............................................54 計(jì)數(shù)器 .................................................................6 計(jì)數(shù)器的作用 ........................................................6 計(jì)數(shù)器的工作情況 ....................................................6 控制信號(hào)燈的譯碼電路的真值表 ........................................7 狀態(tài)譯碼電路 ........................................................95 譯碼顯示電路 ...........................................................9 共陽極LED七段數(shù)碼管 .................................................9 74LS247譯碼器 ......................................................11 以下介紹各引腳的功能： .........................................11 數(shù)碼連接譯碼電路 ...............................................11 真值表 .........................................................126 555振蕩器構(gòu)成的秒脈沖電路 ...
