摘　　要：为了提高低压电力线载波通信的实用性,需要配合使用合适的高层通信协议。因此,有必要对低压电力线载波通信网络的拓扑结构和特性进行分析。文中通过对低压电力线载波的特殊性的研究,提出了总线分裂的概念,并指出该网络的拓扑结构是一个复杂的具有强时变性的有向图,传统的总线监听方案在该网络中也将失效。因此,必须采用一个全新的具有很强自适应能力的网络协议才能满足低压电力线载波通信网络的需要。In order to improve the practicability of the low voltage power line carrier communication (PLCC) some high level communication protocols should be applied. It isnecessary to analyze the topological structure of low voltage power line carrier communication networks and theircharacteristics. Through the research on the particularity of low voltage power line carrier, a concept of bus splitting ispresented and it is pointed out that the topological structure of PLCC network is a complicated digraph with strongtime-varying feature and the traditional bus listening schemes will not be effective in such network. Therefore, to meet the requirement of low voltage PLCC network a brand-new network protocol possessing good adaptive capability should be applied.
