Abstract

The invention relates to a dual-mode electric energy meter communication system and a method. The system comprises a main station, a concentrator, a dual-mode routing module, a carrier communication unit, a micro-power wireless communication unit, a dual-mode communication module, and a smart meter. An output end of the main station is connected to an input end of the concentrator, an output end of the concentrator is connected to an input end of the dual-mode routing module, an output end of the dual-mode routing module is respectively connected to the carrier communication unit and the micro-power wireless communication unit, an output end of the carrier communication unit and an output end of the micro-power wireless communication unit are connected to the dual-mode communication module, and the dual-mode communication module is connected to the smart meter. The dual-mode electric energy meter communication system and the method improve communication efficiency and reliability and achieve simultaneous transmission of a large amount of data. Therefore the dual-mode communication mode not only inherits the advantages of the power line carrier, but also compensates for the insufficient of environmental requirements.

Description

technical field [0001] The invention relates to an electric energy meter communication system, in particular to a dual-mode electric energy meter communication system and method. Background technique [0002] In recent years, the State Grid Corporation of China has put forward the strategic goal of developing a "strong and smart grid", which needs to be based on a high-speed, two-way, real-time, and integrated communication system. At present, the low-voltage power line carrier technology plays a major role in the electricity information collection system. The power carrier is affected by signal interference, weather conditions, environmental factors, etc., which will cause the station area to gather data. The success rate is not high. With the decline of the collection success rate, and The percentage of complaints related to the total number of complaints has increased. The single micro-power wireless solution is easily affected by the geographical environment, air humidi...
