The Research And Application Of The Harbor Mobile Crane Monitoring System Based On WinCC

Along with the expansion of the industrial enterprise scale, the supervisory system has also experienced five stages development. Because of the good development of harbor container shipping industry in our country, a wharf must guarantee to understand the scene situation real-time and solution the problem, so it is necessary to have the more reasonable and the perfect real-time monitoring system . Because the productivity of the container crane is the important factors to the production efficiency of the harbor, therefore must promptly discover and forecast the breakdown of container crane. At present, the research of the remote monitoring for the container crane has just started in our country, only some big harbors can remote monitor the container crane equipment, but because of the differend type of PLC, the monitoring system often unable centralized management. This paper union the actual situation and design request of the harbor, based on the WinCC configuration software, utilized the OPC technology and the C/S, B/ S motion, gathers the data of all the kinds of container crane, and designs the supervisory system, realizes the remote motion browsing.This article first introduces the survey and the development of container crane supervisory system, according to the analysis the hoist crane organization, union the actual situation particularity of the harbor, proposes the system structure which gathering the field data based on the ethernet and the OPC technology, uses the OPC server to gather the field data by the drive type, and WinCC communication to the server by the OPC client way.According to the actual request of the MCMS system, proposes the structure and the design style of the supervisory system. Aims at the variable addressing essential technology in the design process to carry on the analysis, proposes the method of creating the middle tag, compare the three kinds of actual method, like the variable evaluation, the variable indirect addressing and the structure tag ,which can solve the question with variable addressing. Because this MCMS system gathering thousand ofvariables, also realizing the remote browsing function, therefore finally decides to use the method with uniting the structure variable and objects of "Picture Window".The analysis of the report and printing function for the configuration software at the present, according to the actual request of the MCMS system which should have alarm reports and the production process quantity report, based on the WinCC configuration software integrating the ODBC/ SQL database, having the standard interface of ActiveX, this paper proposes the method with independently designing the production process quantity report form using the SQL database and VB-Script.Finally has carried on the comparison to the good and bad points of the C/S, B/ S motion, and according to the actual situation analysis of the MCMS system, proposed C/S, B/S unifies the structure way realization remote migration monitoring, and passes in the establishment method of the WinCC C/S, B/S pattern has carried on the detailed explanation to it.
