Local Network Power-Cutoff Detection for Reliable Status Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In local communication networks, especially those used for outdoor lighting systems, communication devices often lose connection due to power supply cutoffs, leading to outdated status information at remote management servers.
Innovation Solution
The integration of power cutoff detection modules and energy storage modules in communication devices allows them to continue operating and sending status updates to remote servers even after power supply cutoffs, ensuring the accuracy of information stored at the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication devices operate without power cutoff detection and energy storage modules, then device complexity is reduced, but reliability of status information at the remote server deteriorates due to power supply cutoffs causing communication loss
Solution Approach 1:
The power cutoff detection module continuously monitors the power supply status before complete power loss occurs. When a power cutoff is detected, the system proactively stores the current status information in the energy storage module and transmits it to the remote server, ensuring that status information is preserved even when power is subsequently restored or lost completely.
Solution Approach 2:
The energy storage module acts as an intermediary between the communication device and the remote server during power cutoff events. It temporarily holds status information and enables the communication module to transmit this data to the server using stored energy, bridging the gap when direct power supply is unavailable.
2Loss of information
If communication devices continuously transmit status updates, then information freshness at the remote server is improved, but energy consumption increases leading to more frequent power cutoffs
Solution Approach 1:
Instead of continuous transmission, the system implements periodic status updates triggered by specific events such as power cutoff detection, status changes, or at scheduled intervals. This event-driven approach ensures that the remote server receives timely status information while minimizing unnecessary energy consumption during normal operation.
Solution Approach 2:
The system implements a feedback mechanism where the remote server acknowledges receipt of status updates. The communication device monitors these acknowledgments and adjusts its transmission behavior accordingly, sending updates only when necessary to maintain information freshness without excessive energy consumption.

AI summary
Example embodiments relate to managing a network that includes multiple communication devices. One example set of devices adapted to form a local network includes at least one first communication device and at least one second communication device. Both the first and the second communication devices include a first communication module to communicate in the local network. The first communication device includes a second communication module. Both the first communication device and the second communication device are adapted to be operationally connected to a power cutoff detection module. The first communication device includes a first energy storage module and is configured to operate in a first power cutoff mode when the power cutoff detection module detects a power cutoff. The second communication device includes a second energy storage module and is configured to operate in a second power cutoff mode when the power cutoff detection module detects a power cutoff.
