摘　　要：在现代智能楼宇范围内,选择具有良好传输性能的合适低压电力线路或供电网格作为通信路径,构建电力线通信网络成为至关重要的问题。本文在对不同的供电功能、电压、相序以及不同场所的实际电力线路进行实测的基础上,采用最小二乘法拟合曲线,按照电力线通信的信道特征、传输性能,对测试数据进行详细地分类比较,分辨出了有效通信路径;并介绍了电力线通信主控网络拓扑、传输矩阵路由算法模型和通信路径的优化建议。结论表明,构建该网络时,通信路径选择的必要性。为电力线通信网络的规划与设计提供依据和参考。In the modem intelligent building, the problem is vitally important to select appropriate low-volt （LV） power lines or power supplying grids with good transmission performance for communication paths. Based on the test of the function and voltage of the power lines in many different cases, the paper compares the test data in detail with the transmission performance and channel characteristic by least-squares method, and from which distinguishes the appropriate communication paths. Meanwhile, the paper introduces the design of the master network topology and the model of routing policies based on transporting matrix, and presents some optimization advices for communication path. The results show that the selection of communication paths is indispensable for construction of this network. It also provides references for the planning and design of PLC network.
