本发明涉及物流系统的运行状态监测与故障诊断领域，具体涉及一种烟草物流系统运行状态监测及故障诊断方法。The invention relates to the field of operating state monitoring and fault diagnosis of a logistics system, in particular to a method for operating state monitoring and fault diagnosis of a tobacco logistics system.
背景技术Background technique
烟草物流系统是一种复杂的综合性生产物流系统，具有一定的特殊性。由于卷烟厂利税相对较高，尤其卷烟年产量在50万箱以上的大型卷烟工厂技术改造起点和目标定位都很高，加之资金充足，其物流系统引领了工业先进水平，一些技术含量高的物流设备在烟草行业得到率先应用，如穿梭车、立体高架仓库、工业机器人、自动导引车(AGV)等在烟厂物流系统中都得到了广泛应用。目前应用于烟草行业的现代物流控制系统更多的偏重于对所管理的物品进行跟踪、统计和分析，对设备运行情况却缺乏卓有成效的故障监控、及预警功能，缺乏对设备可靠的运行统计，无法提供完善的运行分析数据，无法为维护人员提供必要的故障诊断辅助功能，从而导致维护人员在进行设备维护保养时常处于被动，维修及保养效率低下。Tobacco logistics system is a complex and comprehensive production logistics system with certain particularities. Due to the relatively high profits and taxes of cigarette factories, especially large-scale cigarette factories with an annual output of more than 500,000 boxes of cigarettes, the starting point and target positioning of technological transformation are very high, coupled with sufficient funds, their logistics system leads the industry. The equipment has been first applied in the tobacco industry, such as shuttle vehicles, three-dimensional high-bay warehouses, industrial robots, and automatic guided vehicles (AGV), etc. have been widely used in the tobacco factory logistics system. The modern logistics control system currently used in the tobacco industry is more focused on tracking, counting and analyzing the managed items, but lacks effective fault monitoring and early warning functions for equipment operation, and lacks reliable operation statistics for equipment. It is unable to provide complete operation analysis data, and cannot provide maintenance personnel with necessary auxiliary functions for fault diagnosis, resulting in maintenance personnel being often passive when performing equipment maintenance, and repair and maintenance efficiency is low.
随着烟草企业生产规模的扩大、产品品种的增加、先进设备的引入，自动化程度不断提高，这也势必对烟草物流系统设备本身的维护保养和安全管理提出了更高的要求。日益激烈的市场竞争也使众多烟草企业更加重视设备维护管理，以降低企业生产成本，提高产品竞争力。为保证物流系统安全、经济、稳定运行，物流设备的故障监测诊断将从以时间为基准的方式转变到以状态为基准的方式，其内容包括状态监测与故障诊断两个方面：前者通过提取故障的特征信号为状态维修提供检修依据，后者则分析、处理所采集的状态信息。现阶段由于三维监控技术尚未成熟而且成本偏高，国内面向烟草物流系统的状态监测仍多采用Intouch、wincc、iFIX等二维组态软件，Intouch一种工业自动化组态软件,Wonderware公司产品。相关系统如基于Intouch软件的烟草物流自动化监控系统、基于Intouch9.0组态软件的制丝生产线监控系统、青岛烟卷烟厂的iFIX制丝线监控系统、济南将军烟草集团的基于wincc的链条炉监测系统等。这些系统功能齐全，性能稳定，在实际生产中发挥了具体作用；但是界面粗糙、直观性差、可视化程度低，极大地降低了系统的实用性。随着故障诊断技术的不断成熟以及在我国航空、化工、冶金、电力等行业的成功应用，面向烟草行业的设备故障诊断系统也正如雨后春笋般的萌芽产生，相关系统如基于Web的烟草机械远程故障诊断服务系统、云南昆船设计研究院开发的烟草设备状态监测和预测维护系统、青岛市局开发的仓储分拣设备故障监测系统、兰州交通大学机电技术研究所研究的有轨巷道堆垛机故障诊断系统等，这些系统具有简易的故障监测、诊断或预测功能，在一定程度上提高了设备故障维修效率和降低了设备故障率；但是对于突发故障、复杂故障无法进行深入分析和精确诊断，不能给维修人员提供有效的故障处理帮助。With the expansion of the production scale of tobacco companies, the increase of product varieties, the introduction of advanced equipment, and the continuous improvement of automation, this will inevitably put forward higher requirements for the maintenance and safety management of the tobacco logistics system equipment itself. The increasingly fierce market competition has also made many tobacco companies pay more attention to equipment maintenance and management in order to reduce production costs and improve product competitiveness. In order to ensure the safe, economical and stable operation of the logistics system, the fault monitoring and diagnosis of logistics equipment will change from a time-based approach to a state-based approach, which includes two aspects: status monitoring and fault diagnosis: the former extracts faults The characteristic signal of the condition-based maintenance provides the maintenance basis, and the latter analyzes and processes the collected condition information. At this stage, due to immature 3D monitoring technology and high cost, the state monitoring of domestic tobacco logistics systems still mostly uses 2D configuration software such as Intouch, wincc, and ifix, Intouch is an industrial automation configuration software, and Wonderware products. Related systems such as the tobacco logistics automation monitoring system based on Intouch software, the silk production line monitoring system based on Intouch9.0 configuration software, the iFIX silk production line monitoring system of Qingdao Cigarette Factory, and the wincc-based chain furnace monitoring system of Jinan General Tobacco Group Wait. These systems have complete functions and stable performance, and have played a specific role in actual production; however, the rough interface, poor intuition, and low degree of visualization greatly reduce the practicability of the system. With the continuous maturity of fault diagnosis technology and its successful application in my country's aviation, chemical industry, metallurgy, electric power and other industries, equipment fault diagnosis systems for the tobacco industry are also sprouting like mushrooms after rain. Related systems such as web-based remote fault diagnosis of tobacco machinery Diagnosis service system, tobacco equipment condition monitoring and predictive maintenance system developed by Kunming Shipbuilding Design and Research Institute in Yunnan, storage and sorting equipment fault monitoring system developed by Qingdao Municipal Bureau, rail roadway stacker failure researched by Lanzhou Jiaotong University Electromechanical Technology Research Institute Diagnostic systems, etc. These systems have simple fault monitoring, diagnosis or prediction functions, which to a certain extent improve the efficiency of equipment fault maintenance and reduce the equipment failure rate; however, in-depth analysis and accurate diagnosis of sudden faults and complex faults cannot be performed. Can not provide maintenance personnel with effective troubleshooting help.
