全文約3000字 論述翔實(shí)

摘要
目前國內(nèi)十字路口的交通燈控制一般是定時(shí)切換控制的。在當(dāng)今高速發(fā)展的社會里，交通問題成為大家關(guān)注的社會問題，汽車數(shù)量的直線上升及現(xiàn)有的定時(shí)切換控制交通方式的局限性都使得我們有必要尋求一種智能的交通控制系統(tǒng)，基于此本論文的思路是:通過探測器(即電磁感應(yīng)線圈)探測出汽車的流量后自動調(diào)節(jié)紅綠燈的時(shí)長。控制器采用可編程控制器(PLC)來實(shí)現(xiàn)。

Abstract
At present ,our country traffic lights control generally is timing.In now high speed develop of society, the traffic problem becomes the social problem that everybody pay attention to, the car quantity runs high straightly and the timing control of the traffic lights exist the bug to all make that us have necessity to look for a kind of intellective transportation control system . According to the way of thinking of this thesis is: the hours of the traffic lights are automatically regulated after the locators(namely electromagnetic induction coil) have explored a discharge of the vehicle .The discharge of the vehicle records the number and the long control in hour of the traffic light can be come by PLC to realize.
Keywords
intelligence traffic，Detection，Number cars，PLC
