AUTOMATIC METER READING SYSTEM BASED ON WIRED AND WIRELESS COMMUNICATION FOR UNDERGROUND DISTRIBUTION LINE AND METHOD THEREOF

摘要

PURPOSE: An underground remote metering system using wired/wireless communication is provided to improve accuracy of a metered data collection procedure and minimize collection time. CONSTITUTION: An underground remote metering system comprises data concentration devices(100a,100b,100c), a wireless collector(200), and a wireless communications modem(220). The data concentration device is installed in a ground transformer and transmits metered data collected from a watt-hour meter of a consumer to an underground high-voltage line section using an FDD(Frequency Division Duplex) power line communication repeating method. The wireless collector comprises the data concentration device and a wireless mesh network. The wireless collector comprises a low rank wireless mesh network with the wireless communication modems mounted on the watt-hour meter of a nearby consumer. The wireless communications modem collects and stores the metered data by periodically communicating with the watt-hour meter of the corresponding consumer. The wireless communications modem transmits the stored metered data to the data concentration device through the wireless collector.
