Conformance test system and method for low voltage power line broadband carrier communication protocol

Abstract

The invention relates to a conformance test system and method for a low voltage power line broadband carrier communication protocol. The system comprises a software platform used for managing a test case, selecting a use case to run, recording a system operation log, and calculating the conformance of a broadband carrier communication equipment behavior to be measured and a standard protocol; a transparent physical access unit, which is responsible for sending a test command to a carrier channel and reporting a communication message of the carrier channel to the software platform; a carrier bus channel access unit, which is used for simulating the spot carrier communication scene, and providing a test environment for the broadband carrier communication equipment to be measured; and an equipment application interface monitoring unit to be measured, which is used for simulating an upper application service of the broadband carrier communication equipment to be measured, and monitoring the communication behavior and business behavior of the broadband carrier communication equipment to be measured.

Description

Technical field [0001] The invention relates to the field of electricity consumption information collection, and more specifically, to a low-voltage power line broadband carrier communication protocol conformance test system and method. Background technique [0002] At present, the commonly used local communication methods in the electricity information collection system mainly include low-voltage power line carrier communication, RS-485 communication, micro-power wireless communication and other communication technologies. Low-voltage power line carrier communication technology refers to a communication technology that uses 220V power frequency distribution network to transmit high-frequency and weak electrical signals. Due to the widespread distribution of power line networks, using power lines as communication media does not require hole-punching and wiring indoors to rebuild the communication network. It has the advantages of low cost and convenient connection. It has attract...

AI Technical Summary

Problems solved by technology

The low-voltage power grid is not designed to transmit high-speed data. The components that make up the power grid are designed to minimize the loss of power transmission and ensure reliable transmission of low-frequency current. Therefore, many problems will be faced when transmitting signals on low-voltage lines. For example: complex interference noise, small line impedance, strong signal attenuation, etc.
