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 交通信號燈的設計目的以及要求 ...........................................12 交通信號燈基本原理及設計方法 ...........................................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 計數(shù)器 ....................................
