摘　　要：介绍了一种基于LonWorks电力线通信模式的HOST-BASE结构控制器,通过PLT-22的双频载波传输特性配合MC143150实现了在电力线上的可靠通信。控制器内部主机AT89S51与从机MC143150之间采用Slave_B并行传输模式,数据通信通过传递虚拟令牌得以实现,解决了数据总线冲突问题。应用表明:控制器在主干式网络上通信可靠,无需重新布线,即插即用,具有很大的推广价值。LonWork controller based on power line communication mode achieves reliable communication using PLT-22 featured dual-band transmission and MC143150.Host-based LonWorks controller utilizes Slave_B parallel transmission mode between master processor AT89S51 and slave processor MC143150,which realizes data communication by virtual token transmission,and solves problem of data bus preemption.Practical application in electric power system shows LonWorks controllers applied on backbone network keep reliable communication without wiring again,and can plug and play.So it will have great promotional value.
