【摘要】 目前，监控与数据采集系统(SCADA)正逐渐应用到各行各业中。近年来，随着我国把天然气作为重点发展的能源，燃气行业也成为了SCADA系统重点发展的领域。 成都市煤气总公司作为国内最早供应天然气的专业公司之一，供气规模已列全国第五。面对其供气任务重、输配管理情况日益繁杂的局面，迫切需要建设一套现代、高效的计算机自动监控系统来适应天然气输配系统不断增长的生产调度、运行管理的需求。SCADA系统不仅能成为燃气安全生产运营的工具，也能为管网输配优化调度、故障分析、辅助决策提供科学的手段。它的应用将使成都市燃气输配管网系统的生产调度、输配管理更科学合理、更加现代化。 为了使SCADA系统在成都市燃气输配管网系统中发挥更完善的功能，本文就计算机硬件、网络通信、软件领域的新技术在SCADA系统中的引入及应用入手进行有益的探索。首先分析了国内外燃气行业SCADA系统应用的发展与现状，然后对成都市煤气总公司SCADA系统的项目建设背景、项目建设目标提出了总体设计方案及设计原则。接着按照总体设计方案把SCADA系统结构分成远程终端站(RTU)、通信系统、调度控制中心(MCC)三个部分，分别设计，并对设计方案实施提出了行之有效的解决方法。本文最后对SCADA系统的远期发展进行了展望。更多还原

【Abstract】 Nowadays, Supervisory Control And Data Acquisition (SCADA) system is penetrating into every kinds of fields. Recently, with the government putting more notice on developing natural gas as a kind of supplementary energy, gas industries become an important field for SCADA’s developing.Chengdu Gas Corporation (CGC), as one of oldest companies in this field to provide natural gas, it’s gas scale ranks fifths in our country. In face of its heavy task and complex management in transporting and distributing gas, and in order to meet the need of the growth of the Gas Transportation-Distribution Systems’(GTDS) dispatchment and manager, a sort of modern and effective computer system-automatic supervising and controlling system-is needed. SCADA not only can be a tool to produce and transport safely, but also can provide scientific methods to optimize network transportation-distributing dispatchment, analysis, and assistant decision-making. It’s application will make the work of Chengdu GTDS more sound and morden.In order to make SCADA system exert more perfect function in Chengdu GTDS, the research did some beneficial work on introduction and application of the new technique in the fields of computer hardware, network communications and software. Firstly, the author analyzed the present condition and development of SCADA system’s application inland and overseas, secondly, according to the background and aim of CGC SCADA system’s item construction, he put forwardcollectivity design and the design principle .In succession, in term of the design scheme, the author divided SCADA system into three parts (Remote Terminal Unit, Communication System, Main Control Center), and designed them separately, at the same time, he offered an effective resolution to the related problems. In the end, the author set forth his views on SCADA systems’ development in the future.更多还原
