Unified Address Generation for Remote Smart Meters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing remote smart meter reading systems face complexity and increased resource consumption due to the need for complex procedures to map and manage individual IP addresses, MAC addresses, and meter IDs across different layers for communication, which complicates system operations and resource management.
Innovation Solution
An address generating device and method that generate EUI-48 bit and EUI-64 bit MAC addresses, as well as IPv6 addresses based on a meter ID, using hexadecimal conversions and bit manipulations to simplify address generation and mapping, thereby reducing system complexity and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual IP addresses, MAC addresses, and meter IDs are operated with respective systems in respective layers, then communication management is achieved, but system complexity and resource consumption increase
Solution Approach 1:
The patent merges the management of meter ID, MAC address, and IP address into a unified address generation system. The server generates all three address types based on a single meter ID using consistent bit manipulation rules, eliminating the need for separate management systems and reducing overall system complexity while maintaining communication reliability.
Solution Approach 2:
The meter ID serves multiple functions simultaneously: it acts as the base for generating MAC addresses, IP addresses, and serves as the unique identifier itself. This multi-functionality reduces the number of separate address systems needed and simplifies the overall address management architecture.
2Reliability
If IP-MAC matching tables are managed by using ARP protocol, then MAC address resolution is achieved, but resource consumption increases
Solution Approach 1:
The server performs preliminary generation of MAC addresses and IP addresses based on the meter ID before communication occurs. By pre-establishing the address mappings through deterministic bit manipulation rather than requiring runtime ARP resolution, the system reduces resource consumption during actual communication operations.
Solution Approach 2:
The address generation system is self-sufficient, deriving MAC and IP addresses directly from the meter ID through built-in bit manipulation logic. This eliminates the need for external ARP protocol interactions and associated resource consumption for address resolution.

AI summary
The present invention relates to an address generating device of a remote smart meter reading system, and a method therefor, the device including: a first MAC address generation unit expressing, in four bits, respective numbers of a meter ID of a watt-hour meter, and then converting the numbers into hexadecimal numbers so as to generate a first MAC address of 48 bits; a second MAC address generation unit generating a second MAC address of 64 bits by adding bits to the first MAC address; a first IP address generation unit expressing, in four bits, the respective numbers, and then converting the numbers into the hexadecimal numbers and adding bits thereto so as to generate a first IP address of 64 bits being used as an interface ID of IPv6; and a second IP address generation unit generating a second IP address using the second MAC address as the interface ID.
