摘　　要：在工业现场中 ,现场总线获得了越来越多的应用。但在解决工业环境及过程控制环境下的许多移动对象 ,旋转对象 ,危险环境对象的监测与控制问题仍有局限 ,为此设计了由无线局域网IEEE 80 2 .11和现场总线CAN相结合的一种全新的无线现场总线控制方案。文章介绍了无线现场总线的具体的方案设计 ,分析了其数据传输的实时性 ,并着重于网络结合的关键技术进行了探讨。In the production field of industry environment, fieldbus are widely used. But facing the measurement and control of some mobile, rotated or the dangerous objects, fieldbus still raised several issues that the solutions have not been able to solve satisfactorily. So we designed a grand new wireless fieldbus system which bases on the wireless LAN IEEE802.11 and the fieldbus CAN. In this article, we introduce the project of the wireless fieldbus, analyse the real-time character of the data, and discussed some key technological problems of the net integration.
