Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Utility meter interface units (MIUs) face challenges in accessing and using multiple wireless networks due to non-existent or unconfigured third-party networks at installation, requiring costly reconfiguration and potential errors, which affects resource utilization and communication efficiency.
Innovation Solution
The MIU is equipped with a network selection service that allows access to and use of multiple wireless networks, including mobile, fixed, and third-party networks, even if they were not present at installation, using preference information and back-off periods to optimize resource utilization and communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MIUs are configured with multiple wireless networks at installation, then network access flexibility is improved, but configuration complexity and cost increase
Solution Approach 1:
The MIU is pre-configured with a database of multiple wireless networks including third-party networks during manufacturing, before deployment. This preliminary configuration eliminates the need for complex field reconfiguration when networks become available, as the MIU already contains network credentials and parameters that can be activated when the networks are deployed.
Solution Approach 2:
The MIU is designed with universal multi-functionality to support multiple types of wireless networks (mobile, fixed, and third-party networks) through a single device. The network selection service enables the MIU to automatically detect, evaluate, and switch between different network types, making the device adaptable to various network environments without requiring separate configurations for each network type.
2Reliability
If MIUs use multiple wireless networks, then communication reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The network selection service implements dynamic network selection and switching capabilities. The MIU continuously monitors network availability and performance metrics, automatically selecting the most appropriate network for data transmission. This dynamic approach ensures communication reliability by switching to alternative networks when primary networks fail, while optimizing resource utilization by selecting networks based on current conditions rather than static configurations.
Solution Approach 2:
The system incorporates feedback mechanisms where the MIU evaluates network performance and availability, then adjusts its network selection decisions accordingly. The network selection service uses feedback from network status monitoring to determine which networks to access and when to switch between networks, balancing communication reliability with efficient resource utilization.
3Ease of operation
If MIUs automatically detect and join third-party networks, then ease of operation is improved, but risk of errors and security issues increases
Solution Approach 1:
Third-party network credentials and security parameters are pre-configured in the MIU's network database during manufacturing, before the MIU is deployed to the field. This preliminary configuration ensures that when third-party networks become available, the MIU can automatically detect and join them using pre-validat ed credentials, reducing errors from manual configuration while maintaining security through pre-established authentication mechanisms.
Data Source
AI summary
A method, a device, and a non-transitory storage medium are described in which a meter interface device may attempt to join a third party wireless network, in addition to a mobile transceiver network, in response to a power-up procedure or a reset procedure. Additionally, the meter interface device may simultaneously operate in multiple modes of communications. The meter interface device may select the third party wireless network based on preference information and back-off information. The meter interface device may wait a back-off period, after an unsuccessful attempt to join the third party wireless network, before re-attempting to join the third party wireless network. The meter interface device may also attach to one or multiple other networks including a fixed network.
