【摘要】：本文以提高起重机安全运行,提高装卸效率,加强对电气故障的监测和诊断为目标,采用监控管理技术,开展垃圾液压桥式起重机监控管理系统的研究。应用西门子S7-300系列PLC和组态软件WinCC设计监控管理系统,实现由一台监控主机同时监控三套起重机PLC系统,不仅可以减少操作人员工作强度,提高生产率,而且可以实时监视设备运行状况和故障报警,提高起重机系统和操作人员的安全性能,并能提供历史数据查询,为维护和修理带来极大的方便。 本文先分析系统的特点及功能,结合监控系统的发展,提出系统的网络结构、硬件配置及关键技术,确定下位机与现场设备间采用现场总线进行通讯,上位机与下位机通过工业以太网进行数据通讯。 接着对系统进行设计,其中监控管理系统分为两部分,第一部分为PLC控制系统,第二部分为控制管理系统。PLC控制系统应用西门子S7-300系列PLC控制现场设备,运用STEP 7编程软件进行程序设计,根据起重机的工作原理,完成起重机起升、大车、小车等机构的PLC控制程序,并用PLCSIM进行了模拟仿真。控制管理系统运用西门子组态软件WinCC设计上位机监控画面,采用以太网中的TCP/IP通讯协议作为外部通道,由于在一台上位机中同时监控三台起重机,加上对直接变量和结构变量的分析,确定采用监控画面采取结构变量和画面窗口相结合的方法进行设计,并分别对各机构的监控界面、趋势界面、报警界面、用户管理界面等进行了详细叙述。 最后根据系统报表的需求分析,结合目前组态软件的报表功能特点,对系统中重要的作业报表和设备维护报表,采用VB脚本和SQL Server 2005数据库相结合的方法进行设计。
[Abstract]:In order to improve the safe operation of crane, improve the efficiency of loading and unloading, and strengthen the monitoring and diagnosis of electrical faults, the monitoring and management technology is adopted to carry out the research on the monitoring and management system of the garbage hydraulic bridge crane. Siemens S7-300 series PLC and configuration software WinCC are used to design the monitoring and management system, which can monitor three sets of crane PLC system simultaneously by one monitor host. It can not only reduce the working intensity of operator, but also increase productivity. Moreover, it can monitor the running condition and fault alarm of the equipment in real time, improve the safety performance of crane system and operator, and provide historical data query, which brings great convenience for maintenance and repair. In this paper, the characteristics and functions of the system are analyzed, and the network structure, hardware configuration and key technology of the system are put forward in combination with the development of the monitoring system, and the communication between the lower computer and the field equipment is determined by the field bus. The upper computer and the lower computer communicate with each other through industrial Ethernet. Then the system is designed, in which the monitoring and management system is divided into two parts, the first part is the PLC control system, the second part is the control management system. The PLC control system uses Siemens S7-300 series PLC to control the field equipment. According to the working principle of crane, the PLC control program of crane hoisting, trolley and trolley is completed by using STEP 7 programming software, and the simulation is carried out with PLCSIM. In the control management system, Siemens configuration software WinCC is used to design the monitor screen of the upper computer, and the TCP/IP communication protocol in Ethernet is used as the external channel, because three cranes are monitored simultaneously in one upper computer. In addition to the analysis of direct variables and structural variables, it is determined that the method of combining structural variables and screen windows is adopted to design the monitoring screen, and the monitoring interface, trend interface and alarm interface of each mechanism are respectively designed. User management interface is described in detail. Finally, according to the demand analysis of the system report, combining the function characteristic of the present configuration software, the important job report and the equipment maintenance report in the system are designed, and the method of combining VB script and SQL Server 2005 database is adopted to design the important job report and equipment maintenance report in the system.
