摘要:當(dāng)今社會(huì)，信息技術(shù)的迅猛發(fā)展己經(jīng)深入到各個(gè)領(lǐng)域，對(duì)傳統(tǒng)的監(jiān)控模式產(chǎn)生了極大的影響。現(xiàn)場總線技術(shù)以其結(jié)構(gòu)簡單、便于遠(yuǎn)程控制、遠(yuǎn)程診斷、可靠性高、開放性等多種優(yōu)勢日漸成為自動(dòng)化領(lǐng)域的熱點(diǎn)。基于現(xiàn)場總線的控制系統(tǒng)（ FCS）以其諸多優(yōu)點(diǎn)在工業(yè)監(jiān)控領(lǐng)域引起了一場劃時(shí)代的變革。交通信號(hào)控制是管理運(yùn)輸網(wǎng)絡(luò)的一種基本手段，人們普遍意識(shí)到交通信號(hào)控制系統(tǒng)的作用還未得到完全發(fā)揮。隨著智能運(yùn)輸系統(tǒng)（Intelligent Transportation System，簡記為ITS）的發(fā)展，城市交通控制的研究遠(yuǎn)未完善，交通實(shí)時(shí)控制依然是最重要的研究和發(fā)展項(xiàng)目之一。本文首先介紹了現(xiàn)場總線的現(xiàn)狀、研究意義以及發(fā)展現(xiàn)狀，給出了PROFIBUS網(wǎng)絡(luò)配置方案，分析了系統(tǒng)的硬件配置，給出了元件明細(xì)表以及硬件結(jié)構(gòu)圖。然后分析了PROFIBUS協(xié)議結(jié)構(gòu)以及總線存取協(xié)議，介紹了系統(tǒng)各控制對(duì)象，分析了PLC模塊安裝排布順序及地址分配、西門子PLC變量表以及存儲(chǔ)器的分布，在此基礎(chǔ)上進(jìn)行了程序設(shè)計(jì)，并且作了簡要說明。

Design of Urban Traffic Control System Based On Profibus
 
Abstract: Nowadays，as the development of information technology, the traditional way of monitor and control has been influenced deeply．Fieldbus technology is becoming more and more popular because of its simpleness in structure and control in distane and diagnose in distance and high reliability and openness. Control system based on Fieldbus（FCS） has caused an epoch－making change in Industry control realm. Traffic signal is an essential element to manage the transportation network. Nevertheless，it is widely accepted that the benefits of traffic control systems are not being fully realized．Along with the movement of intelligent transportation system（ITS），traffic control remains one of the most heavily funded research and development items. First, this paper introduced the present condition of Fieldbus and the Profibus technology, and then a traffic control system based on PROPIBUS-DP was designed．The hardware arrangement of system was analyzed , the definite and detailed table of components and the texture figure of hardware were introduced. The agreement structure of PROFIBUS and the memory agreement were given. Every objection controlled by the system was also introduced; The installment sequence of PLC module, arrangement of address , the table of Siemens variable and the arrangement of RAM were analyzed,too. And programs and the explanation in concise were designed.
