Automatic meter reading system and method for underground distribution line using wired/wireless communication
First Claim
1. An automatic meter reading system for an underground distribution line using wired/wireless communication, the system comprising:
- at least one Data Concentration Unit (DCU) installed in a ground transformer, and configured to send meter reading data, obtained from an electronic meter of each consumer, to an underground high-voltage distribution line (DL) using a Frequency Division Duplex (FDD) power line communication repeating method;
at least one Wireless Gathering Unit (WGU) installed on a ground rising pipe or at a multi-consumer lead-in wire, and configured to set up a higher wireless mesh network along with the DCU and to set up a lower wireless mesh network along with wireless communication modems mounted on electronic meters of neighboring consumers; and
at least one wireless communication modem configured to set up the lower wireless mesh network along with the WGU and the wireless communication modems mounted on the electronic meters of the neighboring consumers, to gather the meter reading data while periodically communicating with the electronic meters of the neighboring consumers, to store the gathered meter reading data, and to transfer the stored meter reading data to the DCU through the WGU when the DCU requests the meter reading data.

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.

14. An automatic meter reading method for an underground distribution line using wired/wireless communication, the method comprising:
-
gathering meter reading data while periodically communicating with an electronic meter of a consumer, and storing the gathered meter reading data by a wireless communication modem; sending the stored meter reading data to a Wireless Gathering Unit (WGU), installed on a ground rising pipe or at a multi-consumer lead-in wire, over a lower wireless mesh network by the wireless communication modem when a Data Concentration Unit (DCU) requests the meter reading data; sending the meter reading data, received from a plurality of wireless communication modems, to the DCU installed in a ground transformer over a higher wireless mesh network by the WGU; and sending the meter reading data, received from the WGU, to an underground high-voltage Distribution Line (DL) according to an FDD power line communication repeating method by the DCU. - View Dependent Claims (15, 16, 17, 18, 19)
