【摘要】：随着物流产业近几年在国内外的迅猛发展,对物流产业生产过程的工业信息化要求也越来越高。包件分拣机作为物流处理中心及中转站的高度自动化设备,承担着包件在国内及国际顺利流通的重要任务,在物流行业内占据着极其重要的地位。因此其在生产中的运转正常与否直接影响着生产效率及物流包件的流通。为了应对包件分拣机生产作业过程的突发性问题,本文主要对其一些故障进行了诊断分析,并在此基础上对其上位监控系统进行了研究,实时监控管理设备的运行数据状态,使生产过程实现了信息化管理。本文采用模块化方法将包件分拣系统主机、上包机、格口、电源等模块的硬件结构、运行状态、可能出现的故障进行分析,得到需要采集的各类监控信号；接着分析了PLC作为下位机采集监控信号时的通信方式,通过对PROFIBUS-DP,以太网及串口通信的比较,给出一套经济适用的包件分拣机现场通信方式组合；对于难于发现与分析的通信故障问题,如PROFIBUS通信故障,功能块编程FB125等诊断方式；最后对包件分拣机的上位监控系统进行了研究,其主要利用西门子组态软件WINCC,采用图形化显示界面完成上位监控的开发与仿真。本课题对于包件分拣机的故障诊断与监控系统的研究,可以有效的提高目前国内物流中心分拣作业的信息化管理水平,具有重要的指导意义与实用价值。
[Abstract]:With the rapid development of logistics industry at home and abroad in recent years , the demand for industrial informatization in the process of logistics industry is becoming more and more high . As the logistics processing center and the high automation equipment of the transfer station , it takes the most important role in the logistics industry . In order to deal with the sudden problem of the production operation process of the package sorting machine , this paper mainly makes a diagnosis analysis on some faults and makes a research on its upper monitoring system . In order to monitor the running data state of the management equipment in real time , the production process is managed . This paper analyzes the hardware structure , operation state and possible faults of the package sorting system host , the upper packer , the grid and the power supply module by using the modularization method , and then analyzes the communication mode when the PLC is used as the lower computer to acquire the monitoring signal , and then analyzes the communication failure problem such as PROFIBUS communication failure , function block programming FB125 and so on which is difficult to find and analyze . The research on the fault diagnosis and monitoring system of the bag sorting machine can effectively improve the information management level of the present domestic logistics center sorting operation , and has important guiding significance and practical value .
