Problems solved by technology

[0003] With the continuous promotion and application of object-oriented communication protocol and HPLC technology in the field, the existing detection methods have been difficult to fully adapt to the actual needs of the field
In daily testing work, it often happens that the functions of the electric energy meter and the collection equipment in the laboratory are intact and reliable, but when the equipment is deployed on site, the collection success rate and integrity rate are not good.
[0004] The reason is that the current power carrier communication test system cannot fully study the factors affecting the on-site power line carrier environment and channel conditions, and cannot realize the laboratory reproduction of the complex power line carrier environment on site, so that the above problems occur

Abstract

The invention discloses a power line carrier communication test simulation system and method, and relates to the technical field of power line carrier communication. Through the steps of on-site load waveform acquisition, fundamental waveform reduction curve, noise influence factor injection, waveform simulation reduction, waveform physical output and the like, electric energy meter carrier communication test is realized, and a feature library is established. The beneficial effects of the invention lie in that a carrier module communication field test environment is established; wherein, the influence factors influencing the on-site communication quality are obtained, the on-site environmental factors can be adjusted to obtain the required test waveform, and the on-site feature library of the carrier module communication is perfected.

Description

technical field [0001] The invention relates to the technical field of power carrier communication, in particular to a power carrier communication test simulation system and method. Background technique [0002] At present, the provincial company has more than 20 million smart energy meters in operation, and more than 500,000 collection terminals, all of which adopt the communication method of power line carrier (HPLC). There are a large number of built-in carrier modules in electric energy meters and acquisition terminals, and a large amount of money is invested every year to purchase HPLC modules for on-site fault maintenance. [0003] With the continuous promotion and application of object-oriented communication protocol and HPLC technology in the field, the existing detection methods have been difficult to fully adapt to the actual needs of the field. In daily inspection work, it often happens that the functions of the electric energy meter and the collection equipment ...
