【摘要】 当今社会，信息技术的迅猛发展已经深入到各个领域，对传统的监控模式产生了极大的影响。现场总线技术以其结构简单、费用低、易于维护、可靠性高、开放性等多种优势日渐成为自动化领域的热点。基于现场总线的控制系统以其诸多优点在工业监控领域引起了一场划时代的变革。铁路信号联锁系统是铁路运输的“神经中枢”。在进入信息时代的今天，逐步与通信、计算机技术走向一体化。随着信息技术和网络技术的发展，铁路信号的传统理念正在改变，信号的功能逐步扩大统。因此，新建铁路信号系统以及系统的改造需要一种更安全、更可靠、更高效的解决方案，融合现场总线技术的铁路信号控制系统方案，是一种很好的途径。本次设计以宝钢梅山矿业公司采矿厂的井下铁路信号系统为研究对象，采用具有PROFIBUS组网功能的西门子可编程控制器S7-300系列模块为核心，设计了井下铁路信号控制系统。本文首先结合井下铁路信号的特点介绍了系统的总体设计方案及其特点，然后分为两部分详细介绍了基于STEP 7编程软件的PLC底层控制软件的设计与基于WINCC监控组态软件的上层监控画面的设计，最后结合系统采用的PROFIBUS－DP 网络介绍了控制网络通讯的特点即其实现过程。更多还原

【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 easiness in maintain and high reliability and openness Control system based on Fieldbus has caused an epoch-making change in industry control realm. The interlock system of railways signal is the center of the railway transit. In the information term, the railway signal system will makes one part with the communication and computer technology. With the development of the information technology and network technology, the tradition concept of the railway signal is changing and the function of signal is extending. So constructing a new system or rebuilding a system needs a more safe, reliable and efficient solve method. It is a real good solve way with the fieldbus technology in the railway signal system.The research object of this project is the mine railway signal system of the stope of Mei Shan Mine Corporation of Bao Gang. The SIMENIC programmable controller S7-300 with the PROFIBUS technology designs the mine railway signal control system. First, the article introduces the chief design scheme and peculiarity with the characteristic of the mine railway signal system. Secondly, in two parts, the article specifies the controlling software of PLC with SIMENIC STEP 7 and the monitoring software with the WINCC, which is configured in the top layer. Finally, the article introduces the characteristic and the implement process of the communication network with the PROFIBUS－DP protocol in the system.更多还原
