Power line broadband carrier communication module networking test system of built-in programmable attenuator

Abstract

A power line broadband carrier communication module networking test system of a built-in programmable attenuator comprises a power module, a broadband power-line carrier route module, a processing unit and networking units; the processing unit is connected with the broadband power-line carrier route module, the broadband power-line carrier route module is connected with one networking unit through a shielding radio frequency line, the rest networking units are in cascade connection with other networking units for networking through other shielding radio frequency lines, and the power module is connected with the networking units; the networking units are provided with multiple carrier modules, each carrier module is connected with a single chip microcomputer, and programmable attenuators which can conduct controlling through the carrier communication method of the programmable attenuators are arranged in the networking units, so that the replacement of the carrier module can be convenient, the system setting is not affected, the sizes of attenuation values and carrier signal route directions of communication nodes can be controlled, computer adaptive networking is achieved, client programs such as an ammeter or street lamp control or smart home can be written in the single chip microcomputer, and network tests used for various applications are achieved.

Description

technical field [0001] The invention belongs to the technical field of power line broadband carrier communication, and in particular relates to a power line 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] Th...
