Drawer type power line broadband carrier communication module networking test system

Abstract

Provided is a drawer type power line broadband carrier communication module networking test system including a power supply module, a broadband power line carrier routing module, a processing unit, and networking units, the processing unit is connected with the broadband power line carrier routing module, the broadband power line carrier routing module is connected with one networking unit, the networking unit is in the cascaded networking with other networking units through shielding radio frequency lines, the networking unit includes a circuit substrate, and a programmable attenuator, a signal coupler, a plurality of carrier modules, an electronic switch and a radio frequency connection port arranged on the circuit substrate, the networking units are arranged in a metal-made drawer type installing box, the drawer type installing box includes an installing box body and a drawer, the circuit substrates of the networking units are arranged in the drawer, and the drawer is arranged in the installing box body through guide rails and moves along the guide rails. In the networking test process, the observation and replacement of a communication module can be realized in real time, and the test operation convenience is improved.

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 broadband carrier communication module networking test system. Background technique [0002] As the State Grid Corporation of China and China Southern Power Grid Corporation vigorously promote the broadband power line carrier technology to replace the narrowband power line carrier technology into the automatic meter reading system of electric energy meters, and officially released the low-voltage power line broadband carrier communication technical specifications in July 2017, broadband power line carrier in the electric energy meter The application in the field of automatic meter reading has begun to enter a white-hot state. For this reason, each provincial network company and each meter manufacturer needs to build a set of networking test platforms for power line broadband carrier communication modules, and test the ef...

Problems solved by technology

However, the biggest disadvantage of this test system is that the networking unit is placed in a fully enclosed metal shielding shell, and it is not convenient to observe and replace the communication module in real time during the networking test process. No matter the installation, debugging or test operation, it will bring great harm to the operator. Inconvenience, poor user experience
