摘　　要：为解决PROFIBUS-DP(Process Field Bus-Decentralized Periphery)总线设备接入Wi-Fi(Wireless Fidelity)的问题,给出了基于Wi-Fi的PROFIBUS-DP的无线Web接入方法。在分析PROFIBUS-DP现场总线和Wi-Fi两种异构网络结构和网络协议的基础上,采用嵌入式网关方法,使两种异构网络互联通信,并设计了基于B/S结构的Web无线客户端,使设计的无线客户端能借助Wi-Fi网络对PROFIBUS-DP现场总线的设备进行监控。对系统数据的测试结果表明,采用该方法数据传输准确,接入可靠。In order to solve the problem of PROFIBUS-DP（ Process Field Bus-Decentralized Periphery） bus device access to Wi-Fi,this topic discusses the wireless Web client based on Wi-Fi for PROFIBUS-DP. At first,we get a further research and analysis about the network structures and network protocols of both PROFIBUS-DP and Wi-Fi. Then we use the method of embedded gateway to finish the interconnection communication of the two kinds of heterogeneous networks. At last,we design the wireless web client based on the structure of B / S that the wireless client can monitor the devices of PROFIBUS-DP with the help of Wi-Fi. Finally,the result data is tested and the data is transmitted correctly. So the access method is reliable.
