【摘要】 随着经济全球化和贸易自由化的不断深入和发展,货物的集装箱运输已经成为-种先进的、高效的、快速的现代化运输方式。集装箱堆场,作为集装箱运输的枢纽,衔接着内陆和沿海的集装箱港口和码头,在集装箱运输中发挥着极其重要的作用。提高集装箱堆场的管理水平和设备的自动化程度是提升装卸作业效率的重要手段。组态软件作为自动化技术、网络技术、计算机技术发展的产物,被广泛应用于工业自动化控制领域的过程通信和过程可视化,为构筑满足用户要求的管理信息系统提供了强大的技术支撑。本论文主要对基于WinCC的堆场管理与自动化系统的设计与开发进行了比较详尽的描述,最终实现了基于WinCC的堆场管理与自动化系统。堆场管理与自动化系统是以组态软件WinCC作为系统开发的核心,辅以VB开发的数据采集处理程序共同构成了整个系统。系统通过集装箱起重吊装平台模型提供的PLC编程接口访问和处理PLC中的数据。WinCC负责过程画面显示、设备控制、过程数据归档与显示、报警记录归档与显示等模块的设计与开发。VB开发的数据采集处理程序模块主要包括集装箱自动化入场、场内集装箱查询、箱位使用情况查询、集装箱自动化出场。同时专门设计了后台数据库。论文也详细介绍了组态软件WinCC与集装箱起重吊装平台模型PLC的通信方法以及VB数据采集处理程序访问数据库的方法。WinCC与PLC的通信,采用OPC技术实现WinCC和PLC编程接口的通信连接。而VB数据采集处理程序则采用ADO对象模型实现与后台数据库服务器的数据交互。本系统在实验室环境下进行了多次测试。测试结果表明,本系统具备数据采集与处理功能、具备过程操控和报警功能。系统运行稳定。更多还原

【Abstract】 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.更多还原
