Abstract
Disclosed herein is an automatic meter reading system for an underground distribution line using wired/wireless communication. The system includes at least one Data Concentration Unit (DCU), at least one Wireless Gathering Unit (WGU), and at least one wireless communication modem. The DCU is installed in a ground transformer, and sends meter reading data to an underground high-voltage distribution line (DL) using a Frequency Division Duplex (FDD) power line communication repeating method. The WGU is installed on a ground rising pipe or at a multi-consumer lead-in wire, and sets up a higher wireless mesh network and a lower wireless mesh network. The wireless communication modem sets up the lower wireless mesh network along with the WGU and the wireless communication modems, gathers the meter reading data, stores the gathered meter reading data, and transfers the stored meter reading data to the DCU through the WGU.
