针对窄带电力线载波通信逐渐成为辅助通信方式过程中空置设备的拆除问题,研究出一种闲置线路上空置阻波器的拆除方法;同时对于仍在使用的电力线载波通道,找到符合现状的频率分配方式。首先,分析了频率分配及空置阻波器拆除方法的理论依据;其次,通过对比几种典型的电力线载波通信技术频率分配方法,并结合现场需求,设计了频率分配与空置阻波器拆除方法及相应流程;最后,采用Visual Basic实现软件设计。测试结果表明,该频率分配与空置阻波器拆除方法可以快速准确的实现频率的分配及空置阻波器的拆除判断,软件功能满足应用要求。

The narrow band power line carrier communication has gradually become the auxiliary communication mode. In this process, aiming at the problem of dismantling the vacant equipment, a method of removing the vacant trap on the idle line is studied. At the same time, for the power line carrier channel which is still in use, the frequency allocation mode which is in line with the current situation is studied. First, the theory of frequency allocation and vacant line traps demolition methods is analyzed. Secondly, through the comparison of several typical power line carrier communication technology frequency assignment method, and combined with the field requirement, the suitable frequency allocation and vacant line traps removal method and the corresponding flow are designed. Finally, Visual Basic is used to design the software. Test results show that this method can quickly and accurately realize the frequency allocation and the removal of the vacant line traps, and the software function meets the application requirements.
