【摘要】 活塞式空气压缩机以其损失小、效率高、压力范围广、适应性较强等优点，广泛应用于工业生产领域。随着矿井生产的现代化和大型化的发展，用风量不断增加，因此对空气压缩机运行的安全性和可靠性要求也越来越高。自动化技术和计算机技术的发展，使得空气压缩机运行更加安全可靠，控制更加简单方便，空气压缩机集中监控系统正是这两种技术结合的产物。本文在了解国内外工业监控技术发展现状的前提下，以某能源股份有限公司下属矿压风机房改造项目为背景，研究了空气压缩机集中监控系统的设计和开发。论文介绍了空气压缩机的工艺特性，并根据现场要求确定了本集中监控系统的任务。通过对三种系统控制方案的比较和选择，最终决定采用基于PLC的分布式监控系统。本课题对控制系统进行了PLC和外部设备的选型，开发了PLC的监控软件和基于WinCC的空气压缩机上位机监控软件，并完成了现场的安装调试。系统运行结果显示本系统具有较高的可靠性和实用性，提高了整个空压机控制系统的自动化、智能化和人性化的水平。在该系统中，可编程控制器(PLC)作为下位机，较好地解决了工业控制领域中普遍关心的可靠性、安全性等问题；而在上位机中利用组态软件开发出友好的用户监控界面，是一种低成本、开发周期短的最佳方案。论文总结了整个研究过程所取得的主要成果，并提出如何进一步提高空气压缩机监控的自动化水平，最终能够实现压风机房的无人值守。更多还原

【Abstract】 Piston compressors are widely applied in the industrial field because of manyof their characteristics such as little expense, high work efficiency, widepressure range, better adaptability and so on. With the development ofmodernization and greatness of mine, the need of compressed wind is increasing.So the demand of security and reliability of the running of air compressors isgetting higher and higher. The development of automation technology and computertechnology has made the running of air compressors more reliable and safer andthe controlling simpler and easier. The centralized monitoring system of aircompressors is a product of these technologies.The thesis starts with the current development situation of domestic andoverseas industrial monitoring technique, takes air compressors reconstructionitem of a branch mine of some energy group Co., Ltd as background, and does someresearch on the design and development of air compressors centralized monitoringsystem.The article introduces the characteristics of arts and crafts of the aircompressors and sets the task for the centralized monitoring system accordingto the spot needs. Through the choosing and comparison of three control schemesof system, it finally decides to adopt the plan of air compressors distributedmonitoring system. The thesis chooses PLC and peripheral equipments for thecontrol system, and develops the PLC monitoring software of the air compressorsmonitoring system based on WinCC. Then it finishes the installation and debuggingof the system. The running result shows that the system has good reliability,stability and practicability and it also has improved the level of automatization,intelligence and humanness of all control system. In the monitoring system ofair compressors, the PLC solves the problems of reliability and safety that manyexperts care for in industrial field, so it is widely applied as the lower level controller. Meanwhile the friendly real time displaying windows which is designedby using configuration software in the super computer is a scheme of low costand snort period.As a conclusion, the article summarizes the main achievements in the wholeresearch course and points out how to improve the level of automation for thecontrol system to realize the final aim of nobody monitoring system of aircompressors.更多还原
