Bimodulus system of checking meter based on OFDM power line carrier and wireless

The utility model discloses a bimodulus system of checking meter based on OFDM power line carrier and wireless, including 485 electric energy meters, bimodulus collector, bimodulus electric energy meter, bimodulus concentrator and main website, the bimodulus collector links to each other through 485 buses and 485 electric energy meters for gather 485 electric energy meter data, the bimodulus concentrator passes through dual -mode communication with the bimodulus collector and realizes data transmission, and the bimodulus concentrator passes through dual -mode communication and links to each other with the bimodulus electric energy meter, and personnel analysis is used with data upload to confession system of backstage main website through long -range radio communication link with gathering the data of coming up to the bimodulus concentrator. Wherein, bimodulus collector, bimodulus electric energy meter, bimodulus concentrator, dual -mode communication indicate respectively based on OFDM power line carrier and wireless bimodulus collector, bimodulus electric energy meter, bimodulus concentrator, the dual -mode communication of GFSK micropower. The utility model discloses avoided the drawback that adopts simple power line communication or micropower radio communication, had the real advantages such as rate height, communication is effectual, the operation conditions is stable of copying, made the system of checking meter really move towards practical.
