The invention provides a concentrator based on wideband carrier communication, and belongs to the field of circuits. The concentrator comprises a system control module and a power module, wherein thesystem control module comprises a MCU main control module and a real time clock module; the real time clock module is connected with the MCU main control module through an IIC bus; a 4G remote uplinkcommunication module, a wideband carrier downlink communication module and a storage module are further connected to the MCU main control module. In downlink communication, electric energy informationof a wideband carrier electric energy meter is acquired by a wideband carrier communication technology, and in uplink communication, acquired electric energy meter information is returned in real time to a power main station for analysis and adoption by a remote 4G communication technology. Signal interference during power line acquisition can be effectively avoided, so that carrier acquisition success rate is increased. By virtue of the 4G remote communication technology, the concentrator can communicate with the main station in real time and efficiently, so that signals and the communication capability are strong and the one-time acquisition success rate of the main station is guaranteed.
