| 摘 要： | 以住宅小区载波抄表信道为测试对象,构建了低压电力线载波阻抗自动测试系统并开发了相应的系统主站管理软件。该系统长期稳定运行,可实现远程多载波频率阻抗自动连续测试及现场USB连接自动扫频阻抗测试等功能。本文根据长期采集的阻抗测试结果,着重分析了阻抗模值、相位在冬季受供暖设备影响下的变化规律,为低压电力线载波通信信道阻抗特性研究和阻抗匹配提供了参考。

| Abstract: | In order to test the residential meter-reading channel,an automatic impedance test system for low-voltage power line carrier communication network was set up and management software was developed.This system can be used for remote automatic continuous impedance testing in the condition of multi-carrier frequency,and for automatic sweep impedance testing by local USB connection,and also capable of operate stably in long term,The variation of impedance modulus and phase under the influence of heating equipment in the winter was analyzed based on long-term test results of the system,and the impedance for low-voltage power line carrier communication channel was provided for impedance matching and characteristics analysis. |
