摘要
设计了一种基于WLAN技术的手持终端系统。该系统通过信息采集、终端软件处理、无线信息发送及数据库交互实现了对库区物料的管理。手持终端平台包括条形码识别模块、无线网络模块以及其他基本功能模块,采用Windows CE操作系统,增强了系统可扩展性。针对工业环境下的无线局域网络应用,设计了一种基于心跳电文的通信状态监测机制。系统使用嵌入式平台下的ADOCE技术进行数据库接口的设计,最终根据现场功能需求设计了终端处理软件。
A handheld terminal system based on WLAN is presented.The material management of reservoir area is realized by information collection,terminal software process,wireless information-sending,database interaction.The handheld terminal platform includes bar code recognition module,wireless network module and other basic function module.The Windows CE operating system enhanced the expansibility of this system.Considered the application of wireless local area network in the industrial environment,a communication status monitoring mechanisms based on heartbeat message is designed.The ADOCE technology in the embedded operating system is used to realize the database interface,at last,the terminal software process is designed according to the functional requirement in the steel factory.
