【正文】 ，對交通控制方法的研究也就自然成為該領(lǐng)域的熱點。 1914 年以及稍晚一些時間，美國的一些城市也出現(xiàn)了交通信號燈。這些問題都是交通運(yùn)輸系統(tǒng)規(guī)劃和交通管理及控制所要解決的難題。 關(guān)鍵詞 PLC； 組態(tài)王； 交通燈五邑大學(xué)本科畢業(yè)設(shè)計 II Abstract Traffic Signal Control System is an important part of the urban traffic control mand system. The reliable operation of the traffic signals is an important guarantee for the fluency of traffic flow. Programmable logic Controller (PLC) with strong antiinterference capability, high reliability, small size, simple programming and other features， it has the widespread application in the automatic control system. This paper is based on the CQM1Omron PLC to control the traffic lights, and take full advantage of the timing / counting, control the order, logical operators, and other functions. This paper also introduces the control procedure’s design method for the realization of PLC control system in traffic signal, as well as its imitation in King View. Between the designs, focused study basic principles and application of the PLC and King View. To research use the traffic light control procedure with the PLC trapezoidal chart and in King View provides visualization monitoring picture simulation traffic light.
