Abstract

The invention relates to a power line broadband carrier communication module networking test system. The system comprises a three phase power supply, an A phase networking unit connected with the A phase of the three phase power supply, a B phase networking unit connected with the B phase of the three phase power supply, a C phase networking unit connected with the C phase of the three phase power supply, a concentrator connected with the three phase power supply by three lines, and a processing unit connected with the concentrator, wherein the networking units on each phase are mutually connected through shielded cables. The networking units are provided with a plurality of carrier modules, and one carrier module is connected with a single-chip microcomputer, so that the carrier modules are convenient to replace, and replacement of any carrier module does not affect system setting; and client programs about control of electric meters and street lamps or smart home can be written in the single-chip microcomputer, so that the networking test system can be used for networking tests of multiple applications.

Description

technical field [0001] The invention belongs to the technical field of power line carrier communication, in particular to a power line broadband carrier communication module networking test system. Background technique [0002] In recent years, as Qualcomm Atheros and Huawei HiSilicon have successively launched power line broadband carrier chips for energy management and home automation, power line broadband carrier technology has gradually replaced narrowband power line carrier technology with the advantages of more stability and higher speed, and entered the energy meter Automatic meter reading system, street light control and smart home. However, the networking test platform for power line broadband carrier communication modules does not have a mature solution that can simulate various complex on-site environments and realize flexible routing methods to test the routing algorithms and networking capability limits of different carrier solutions. . [0003] The closest so...
