Remote meter-reading system and method using duplicated data transmission of packet data transmission and circuit data transmission

A remote meter-reading system for measuring data including an amount of used resource provided to a consuming place and an operating state of a meter in a remote place and transmitting the data to a remote meter-reading server using a duplicate data transmission via packet data transmission and circuit data transmission, the remote meter-reading system comprising:

• an electronic meter which measures an amount of resource used in a consuming place, stores the amount of the used resource in an internal memory, and transmits meter-reading data stored in the internal memory in response to a meter-reading data transmission command;
• a wireless remote meter-reading modem which receives meter-reading data acquired at predetermined intervals in a predetermined duration starting from a reference time from the electronic meter if a predetermined meter-reading time is encountered, packetizes the meter-reading data and unique ID information of the electronic meter, transmits the packetized meter-reading data and unique ID information to the remote meter-reading server through a mobile communication network, sets a channel in response to a request to set a call through the mobile communication network, reads necessary data from the electronic meter in response to a command received from the remote meter-reading server through the channel, and transmits the necessary data to the remote meter-reading server through the channel;
• the mobile communication network comprising a plurality of base stations, a switching unit, and a network inter-working unit for connection with Internet to support the packet data transmission and comprising a plurality of base stations and the switching unit to support the circuit data transmission;
• Internet which is connected with the network inter-working unit and relays the meter-reading data from the mobile communication network to the remote meter-reading server;
• a wireless front end processor (FEP) modem which is connected with an FEP and sets a line to the wireless remote meter-reading modem through the mobile communication network for the circuit data transmission;
• the FEP which is connected with the wireless remote meter-reading modem through the mobile communication network and the Internet according to the packet data transmission, is connected with the wireless remote meter-reading modem through the wireless FEP modem according to the circuit data transmission, 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 an administrator when meter-reading data is corrupted due to noise or distortion in the wireless FEP modem or a line used to acquire the meter-reading data;
• and
• a remote meter-reading server which is connected with the FEP through a local area network (LAN), manages the meter-reading data transmitted using the packet data transmission, checks whether there is any data that has not been received, sets a line to the wireless remote meter-reading modem corresponding to the data that has not been received, requests and receives the data that has not been received through the set line.
