Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient energy data sampling by multiple electronic devices in close proximity leads to increased power consumption and data collisions, resulting in corrupted data packets and reduced network performance due to simultaneous data transmission.
Innovation Solution
Coordination of energy data sampling among devices through sample timing information, where a server determines and distributes sample times to reduce power consumption and data collisions by ensuring devices take turns in sampling energy data from a smart meter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple electronic devices simultaneously sample energy data from smart meters, then data sampling coverage is improved, but power consumption increases and data collisions occur
Solution Approach 1:
The patent implements periodic sampling action by dividing the sampling process into distinct time periods. Multiple devices are assigned different sampling time windows within a coordination period, allowing them to periodically access smart meters in a structured manner that prevents simultaneous access while maintaining comprehensive data coverage across all devices.
2Speed
If multiple electronic devices simultaneously transmit data in the same channel, then data transmission speed is improved, but data collisions occur causing corrupted packets
Solution Approach 1:
The patent segments the data transmission process by dividing it into separate time slots for different devices. Each electronic device is assigned a specific time window within a coordination period to transmit its sampled data, which prevents simultaneous transmissions that cause collisions while maintaining efficient data transfer rates through structured parallel access.
3Productivity
If electronic devices frequently join and leave wireless communication networks for sampling, then data sampling frequency is improved, but radio resource usage increases
Solution Approach 1:
The patent maintains continuous useful action by keeping electronic devices connected to the wireless communication network throughout the coordination period. Devices remain registered with the network and only activate their sampling and transmission functions during their assigned time windows, eliminating the need to repeatedly join and leave the network while maintaining high sampling frequency capability.

AI summary
Systems and methods for coordinating data sampling among devices include a set of electronic devices that may periodically sample energy data from a smart meter according to sample timing information. The sample timing information may specify a set of times to sample energy data for each electronic device. The set of electronic devices may take turns in sampling energy data from the smart meter so that individual electronic devices may reduce power consumption by sampling less frequently. A server may determine the sample times for the electronic devices and may instruct the electronic devices to sample energy data. Additionally, each individual electronic device may leave and/or join wireless communication networks less frequently than if each individual electronic device performed every sample. Accordingly, the coordinated sampling may decrease the radio resource usage and/or bandwidth usage of any individual electronic device.
