摘　　要：在Profibus-DP的无线应用中,一般采用网关法实现Profibus协议与无线通信协议之间的转换。为了解决网关转换延时较长的缺陷,提出采用无线中继法实现Profibus-DP主、从站之间的无线通信。实验结果证实了该方法既能满足Profibus-DP总线的时序要求,又能满足从站实时反应的要求。In Profibus-DP＇s wireless application,the gateway method can be generally used to implement the conversion between Profibus protocol and wireless communication protocol.In order to solve the long delay of the gateway switching,the radio-relay method was proposed to realize wireless communication between Profibus-DP＇s master and slave stations.The experimental results show that this method can meet the timing sequence of Profibus-DP and the real-time reaction of slave stations.
