Patent ID: 7902995

Claim:
A remote meter-reading method using duplicate transmission via packet data transmission and circuit data transmission, the remote meter-reading method comprising: (a) a wireless remote meter-reading modem reading meter-reading data from an electronic watt-hour meter when a predetermined meter-reading time is encountered; (b) the wireless remote meter-reading modem packetizing the meter-reading data and unique ID information of the electronic watt-hour meter into a predetermined format and transmitting them to a remote meter-reading server through a mobile communication network; (c) the remote meter-reading server receiving and managing the meter-reading data from the electronic watt-hour meter and checking whether there is any data that has not been received; (d) when there is data that has not been received within a predetermined time, the remote meter-reading server managing a front end processor (FEP) to set a line to the wireless remote meter-reading modem corresponding to the data that has not been received according to the circuit data transmission; (e) if the setting of the line succeeds, the wireless remote meter-reading modem reading necessary meter-reading data from electronic watt-hour meter in response to a command of the remote meter-reading server; and (f) if the reading of the data succeeds, the wireless remote meter-reading modem transmitting the necessary meter-reading data to the remote meter-reading server through the previously set line, wherein the FEP is connected with the wireless remote meter-reading modem through a wireless FEP modem according to the circuit data transmission and automatically initializes the wireless FEP modem after meter-reading to prevent the wireless FEP modem from being hung up, and generates and sends a warning message to the remote meter-reading server when meter-reading data according to the circuit data transmission is corrupted.
