摘　　要：RFieldbus是在现场总线PROFIBUS基础上研制的一种具有传送IP数据包能力的无线实时通讯系统,又称无线现场总线。本文在介绍了其基本结构后,对该系统的实时性能和差错特性做了理论的分析,随后在实验中对数据交换周期、TCP/IP的吞吐量及丢包率等参数做了详细的测试。评测结果表明,RFieldbus可以在并发TCP/IP流量的情况下满足大多数工业控制环境的实时性能要求。RFieldbus is a modified kind of PROFIBUS fieldbus system featuring th e extended wireless physical layer and the IP transmission capability. This pape r describes the results of a number of tests which were made to assess the RFiel dbus behavior. PROFIBUS-DP cyclic data exchange time, TCP/IP traffic throughput as well as error performance of the transmission mechanisms were evaluated in di fferent scenarios. The results shows that in the industrial environment RFieldbu s system can fully meet the real-time requirement even companied with the TCP/IP traffic.
