摘要
为提高LonWorks系统在电力线信道上进行多进程、多任务并行处理时的实时性,介绍了一种在主机AT89S51与从机MC143150之间采用Slave_B并行传输模式的LonWorks电力线节点。数据通信通过传递虚拟令牌得以实现,解决了数据总线传输冲突问题;节点配以路由器和iLON100构建的主干式网络,保证了数据在电力线信道上的及时处理。实际应用表明,相对于传统基于神经元芯片类型的LonWorks节点,基于Slave_B并行传输模式的电力线节点控制能力得到增强。
In order to improve the real-time performance for LonWorks system parallel processing multi-process and multi-task on information channel of power line, the LonWorks node adopting Slave B parallel transmission mode between master processor AT89S51 and slave processor MC143150 operating on power line is introduced. The data communication is implemented via virtual token transmission to solve the conflict on data bus. The node is equipped with router and the backbone network structured by iLONI00, to ensure prompt data processing on information channel of power line. The practical application shows that comparing with the LonWorks node based on neuron chip, the node based on Slave_B parallel transmission mode intensifies the control capability.
