Abstract

The invention discloses a method for testing the broadband carrier communication performance of a low-voltage power line. The method includes: sending test messages in batches through a carrier bus channel access unit; controlling the attenuation of a carrier communication channel of the carrier bus channel access unit; injecting interference noise to the carrier communication channel; measuring a signal characteristic of the carrier bus channel access unit; and monitoring a communication behavior and a business behavior of to-be-tested communication equipment by employing an application interface message of the to-be-tested communication equipment. According to the technical scheme for testing the broadband carrier communication performance of the low-voltage power line, the communication performance test initiates various communication behavior tests on the carrier channel of interference quantification simulation, the response condition of the to-be-tested equipment on the carrier and application channels is intercepted and recorded, a statistical analysis of the response condition is conducted, quantification parameters of the simulation channel are recorded according to the test equipment, and communication performance assessments of the to-be-tested communication equipment in various interference quantification channels are formed.

Description

technical field [0001] The invention relates to the field of electrical information collection, and more specifically, to a method and system for testing the performance of low-voltage power line broadband carrier communication. Background technique [0002] At present, the local communication methods commonly used 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 the communication technology that uses 220V power frequency distribution network to transmit high-frequency and weak current signals. Because the power line network is widely distributed, using power lines as the communication medium does not require perforated wiring in the room to rebuild the communication network. It has the advantages of low cost and convenient connection. It has attracted more...
