The Design And Implementation Of Yard Mangement And Atuomation System On Wincc

With the deepening of economic globalization and trade liberalization, container transport of goods has been an advanced, efficient and rapid modern mode of transportation. Container yard, as the hub of container transport, is connecting the inland and coastal container ports and terminals. It plays an extremely important role in container transportation. Improving the management level of container yard and equipment automation degree is an important means to improve operation efficiency. Configuration software is a product of the development of automation technology, computer technology and network technology. It is widely used in processing communication and visualization in the field of industrial automation control. It provides a powerful technical support to meet the users’requirements of the management information system.In this thesis, the design and implementation of yard management and automation system based on WinCC have been described in detail. In the end, the system has been achieved. About them, on the one hand the software that is named WinCC has been taken as the core of system development, on the other hand data acquisition and processing procedures that developed by VB have been supplemented. And through the PLC programming interface which is provided by the model of container lifting platform, the data in PLC has been accessed and processed. WinCC is responsible for design and development of many modules which contain the display of process picture, equipment control, archive and display of data, and the archive and display of alarm records. The module of data acquisition and processing procedures that developed by VB includes containers entry automated, containers query, query of space usage, containers out automated. In addition to that, the back-end database has been designed.Besides that, communication method between WinCC and PLC has been described in detail, and the method of data acquisition and processing procedures by VB to access database has also been described. Using OPC technology, WinCC can communicate with PLC, besides that, the OPC can complete the communication by connecting WinCC and PLC programming interface. Using ADO object model, Data acquisition and processing procedures of VB has achieved data exchange with the back-end database server.This system has been tested for many times in laboratory environment. Test results have showed that this system has completed the function of field data acquisition and processing, besides that it also has completed the functions of process control and alarm. The system runs stably.
