随着以太网通信的兴起与迅速发展，TCP／lP协议作为计算机网络的最主要的传输协议被广泛应用于工业以太网控制领域。为了实现生产现场智能称重仪表与管理层直接的数据交换，使用Visual Basic提供的Winsock控件开发了FTP服务端的通信应用程序，实现现场生产数据在管理层的SQL数据库中的存储和查询。基于TCP／lP通信的称重数据管理系统投入实际运行后，可记录和保存生产现场全部称重数据。“,”ln order to achieve the data exchange between the production field intel igent weighing instrument and manage-ment directly,using the Winsock control provided by Visual Basic develop the FTP server communication application,this paper realizes the scene production data in the management of storage and query of SQL database.After the weighing data manage-ment system based on TCP/lP communication into actual running,al production site weighing data can be recorded and saved.
