【摘要】：随着带式输送机单机使用数量的不断增加,有关其控制领域的研究也在不断拓展。本文主要研究的课题就是针对远距离、大功率的带式输送机系统的特点,如何建立一个具备完整功能的监控系统,实现对运输全线的设备控制、实时状态监测以及故障的预警和诊断。文章首先对国内外大型带式输送机监控系统的发展过程进行了调查和比对,分析和总结出有关电控领域和故障诊断领域的技术差距和不足。以山东比纳尼石灰石运输生产线为背景,详细介绍了带式输送机系统的设备组成和控制要求,着重阐述了监测点的配置、网络搭建和软硬件设计。利用西门子S7-300PLC、ET-200、工控计算机、触摸屏以及相关配套通讯设备构建出了大型带式输送机全线集控系统,能够有效实现设备的多方位控制、数据的远距离传输以及人工交互功能。针对故障预警和诊断功能的实现,本文首先从理论的角度介绍了信息融合技术在该领域内的应用背景,相关数学模型和算法实现,并根据带式输送机系统的故障特性设提出了基于信息融合技术的故障诊断策略。利用山东比纳尼带式输送机现场设备所采集到的数据信息,基于MATLAB软件平台对提出的故障诊断策略进行了实例测试。经试验数据分析表明,该策略能够实现大型带式输送机这类复杂系统的故障识别和诊断功能,具有较高的准确性和可信度,能够为全线设备管理和监控提供有效保障。
[Abstract]:With the increasing use of single belt conveyor, the research on its control field is also expanding. The main research topic of this paper is aimed at the characteristics of long-distance and high-power belt conveyor system. How to establish a monitoring system with complete function to realize the equipment control of the whole transportation line, Real time state monitoring, early warning and diagnosis of faults. Firstly, the development process of large belt conveyor monitoring system at home and abroad is investigated and compared. This paper analyzes and summarizes the technical gaps and shortcomings in the field of electrical control and fault diagnosis. Taking the Linanite transportation line in Shandong Province as the background, the equipment composition and control requirements of the belt conveyor system are introduced in detail. The configuration of monitoring points, network construction and hardware and software design are described emphatically. The whole line centralized control system of large belt conveyor is constructed by using Siemens S7-300 PLCU ET-200, industrial control computer, touch screen and related communication equipment. This paper introduces the application background of information fusion technology in this field from the perspective of theory, aiming at the realization of fault warning and diagnosis function. According to the fault characteristics of belt conveyor system, the fault diagnosis strategy based on information fusion technology is put forward. The proposed fault diagnosis strategy is tested based on MATLAB software platform. The analysis of test data shows that the strategy can realize the function of fault identification and diagnosis for complex systems such as large belt conveyors. Has high accuracy and credibility, can provide effective guarantee for the whole line equipment management and monitoring.
