Title:
METER READING METHOD, DEVICE, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/082214
Kind Code:
A1
Abstract:
A meter reading method, a device, and a system, pertaining to the technical field of electric power. The system comprises: a broadband carrier concentrator sending to a dual-mode communication module and to respective broadband carrier electricity meters a first broadband carrier signal carrying a meter reading instruction (S601), receiving a second broadband carrier signal sent by the dual-mode communication module and a third broadband carrier signal sent by each broadband carrier electricity meter and carrying electrical measurement information of the broadband carrier electricity meter (S602), and storing electrical measurement information carried in the second broadband carrier signal and storing the electrical measurement information carried in the third broadband carrier signal (S603); and the dual-mode communication module modulating and demodulating the received first broadband carrier signal to obtain a first narrowband carrier signal (S402), sending the first narrowband carrier signal to at least one narrowband carrier electricity meter connected to the dual-mode communication module (S403), receiving a second narrowband carrier signal sent by each narrowband carrier electricity meter and carrying electrical measurement information of the narrowband carrier electricity meter (S404), modulating and demodulating the second narrowband carrier signal to obtain the second broadband carrier signal (S405), and sending the second broadband carrier signal to the broadband carrier concentrator.
