An intelligent
system for collecting readings from electric meters, comprising the following components: several electric meters, a data
concentrator connected to the electric meters, and a
system main
station connected to the
concentrator wirelessly, in which: the electric meter for recording the consumed quantity of
electricity by user, metering the quantity of
electricity, measuring demand and making a fault recording, and supporting a time-sharing measurement and communication with the data
concentrator by
electric power carrier; a concentrator for providing intelligent
relay management, implementing the communication with the electric meters and the
system main
station, the management of communication
route of electric meters and the storage function of data; the system main
station for realizing a stable bi-directional communication with the concentrator and several electric meters, reading data in the concentrator, collecting information on
electric energy,
synchronizing the time of the concentrator and the electric meters associated therewith, renewing
time step tariff rate and meter parameters of the electric meters. Bi-directional stable communication between the main station and the intelligent electric meters and collection of electrical
energy information and the adjustment of parameters of electric meters can be realized by
transmission medium in the present invention. The system of the present invention features complete functions, stable user-friendly operation interface, and has good expansion potential. Therefore this system is an important technical means for user-side management. The present invention greatly improves
management efficiency and
economic benefits in the electrical power department.
