The Design And Realization Of Wireless Bar Code Management System Based On Manufacturing

With the rapid development of enterprise informationization, the usual system, ERP is not able to meet the managing requirements for each producting node and business process. On the background of manufacturing informationization, this paper analyzes a series of problems that enterprises face with, and puts forward the solution of wireless bar code management system, which is based on WLAN and bar code technology and integrates with the information resources of enterprises.The author has studied kinds of WLAN and bar code technologies, analyzing their merits and shortcomings, and puts forward the principles and strategies of management and implement. Wireless bar code management system is mainly composed of Manufacturing Excution sub-System (MES), Warehouse Management sub- System (WMS), and Data Synchronization and Integration Module. The system is developed in .NET platform, and has two developping environments: PC and RF terminal. RF termini is a kind of intelligence equipment, like PDA, in which software is coded with the .NET Compact Framework. SQL Server series are chosen as database platform, and the database archtechture is based on the targets and the functional requirements. The replication mechanism of SQL Server is applied to realize the distributed database system. Advice about the management and optimization of database is given since the author has experience during his daily job.The design in this paper comes from the wireless bar code project of Double Coin Holdings LTD in 2006, which is widely praised and becomes the first successful case of wireless bar code management in tyre industry in China.
