| 中文摘要: |
| 文章提出了一种室内低压电力线载波通信传输效率的模型，可获得多枝节、多阻抗负载的室内电力线通信系统频带为1~300 MHz的传输特性。传输效率模型由电力线材料本身固有物理量及其所处环境的参数推导而来，模型基于对电力线每个枝节连接截面的传输效率分析，得到系统总的传输效率。同时利用实测的幅频特性，对双线传输线分析得到的模型进行了修订，使模型计算结果与出其他不同模型拓扑的传输效率测试结果相吻合，对实际的电力线载波通信系统中频带的预选有指导意义。 |
| 英文摘要: |
| An indoor low voltage power line carrier communication transmission model is proposed, which is suitable for multi branch topology, multi load impedance in the frequency band of 1~300 MHz. The transfer function is derived from the parameters of the wire material itself and its environment. The model is based on the transmission efficiency of each connection section, than the total transmission efficiency of the system is obtained. According to the measured amplitude frequency characteristics, the theoretical model is modified to make it possible to simulate the transmission characteristics of different model topologies. The proposed model is helpful in frequency bands pre selection for actual power line systems. |
