[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.
