摘要:交通控制系統(tǒng)是近現(xiàn)代社會隨著物流、出行等交通發(fā)展產(chǎn)生的一套獨特的公共管理系統(tǒng)。要保證高效安全的交通秩序,除了制定一系列的交通規(guī)則,還必須通過一定的科技手段加以實現(xiàn)。隨著社會經(jīng)濟(jì)的發(fā)展,數(shù)字電路交通燈越來越不能滿足日益增長的交通壓力,因此必須尋求一種新的方法來取代這種復(fù)雜而工作不穩(wěn)定的控制系統(tǒng)?,F(xiàn)今PLC技術(shù)飛快發(fā)展,應(yīng)用越來越廣,在工業(yè)自動化中的地位極為重要,廣泛的應(yīng)用于各個行業(yè)。隨著科技的發(fā)展,可編程控制器的功能日益完善,加上小型化、價格低、可靠性高,在現(xiàn)代工業(yè)中的作用更加突出。 本論文就是運(yùn)用PLC技術(shù)來實現(xiàn)對十字路口的交通燈的控制,介紹了可編程序控制器的基本原理,并以標(biāo)準(zhǔn)的十字路口為研究對象,設(shè)計了兩相位交通信號控制系統(tǒng),為了達(dá)到要求,并考慮到節(jié)省電子元件的成本,以達(dá)到最大經(jīng)濟(jì)效益,運(yùn)用三菱系列的PLC來控制交通燈的變化,經(jīng)過對現(xiàn)今交通燈控制系統(tǒng)進(jìn)行實地考察,選擇一種最優(yōu)方案,用以在一定程度上緩解目前交通壓力。 關(guān)鍵詞: 交通燈; PLC;控制系統(tǒng)
Abstract:In modern society traffic control System is served as a unique set of Public management system following the Pace of logistics and transportation. To ensure the traffic efficiency and security,a certain scientific means is required to improve the implementation of a series of traffic rules. The rapid developed social economy makes digital circuit traffic lights fail to meet the increasing traffic pressure. Therefore, new methods must be designed to improve its complexity and instability. Nowadays as the fruit of science and technology, the plc technology has shown its much importance in various industries, and the programmable controller is given much more attention for its miniaturization, low price and high reliability. By designing two phase traffic signal control system on the basic principle of programmable controller, this thesis focuses on the control of traffic intersections through PLC technology with standard crossroads as the research object. In order to achieve maximum economic benefits and save the cost of electronic components, Omron series of PLC is used to control the traffic lights. Also on-the-spot investigation shows an optimal program is taken the current traffic pressure. Keywords: traffic lights;PLC;control system
