IoT Emergency Device Network Reliability via Periodic Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Personal emergency response systems (PERS) and mobile PERS (mPERS) face challenges in maintaining reliable network connections due to the intermittent nature of IoT tracking and emergency response devices, which often conserve battery power by not connecting to networks unless during emergencies, leading to potential failures in communication.
Innovation Solution
A method for testing network connections between remote devices and central stations, involving the remote device sending a test signal and receiving an acknowledgment, with alerts triggered if no response is received, ensuring reliable communication through periodic testing initiated by user instruction or automatic events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the IoT tracking and emergency response device does not connect to the network all the time to save battery power, then energy consumption is reduced, but network connection reliability deteriorates
Solution Approach 1:
The system implements periodic network connection testing at predetermined intervals while the device remains in idle mode. This periodic action allows the device to maintain network connectivity intermittently rather than continuously, reducing power consumption while still verifying connection reliability when needed
Solution Approach 2:
The system performs preliminary network connection tests before actual emergency communication is needed. By proactively testing the network connection in advance during idle periods, the system ensures connectivity reliability is verified before critical communication is required, while maintaining the device in a low-power state
2Reliability
If network connection testing is performed periodically, then network connection reliability is improved, but energy consumption increases
Solution Approach 1:
The testing mechanism is designed to operate periodically at predetermined intervals rather than continuously. This periodic operation maintains network connection reliability through regular verification while significantly reducing energy consumption compared to continuous testing, as the device can return to idle low-power state between test cycles
3Reliability
If the device maintains continuous network connection, then communication reliability is improved, but battery life deteriorates
Solution Approach 1:
Instead of maintaining continuous network connection, the system employs periodic connection tests at predetermined intervals. This approach verifies communication reliability when needed while allowing the device to remain in idle mode with reduced power consumption between tests, thereby extending battery life
Solution Approach 2:
The system autonomously performs network connection tests without requiring continuous user interaction or manual intervention. The automatic testing mechanism operates based on predetermined criteria and intervals, enabling the device to self-verify its communication status while minimizing power consumption by remaining in idle state between tests

AI summary
A method for testing a network connection of an emergency response system at least including a remote device and a central station includes: receiving, by the remote device, a user's instruction or an automatically triggered event for initiating a test of the network connection between the remote device and the central station; in response to the user's instruction or the automatically triggered event, sending, by the remote device, a first test signal to the central station; receiving, by the remote device, a first response signal sent from the central station for acknowledging the first test signal; and in response to receiving no first response signal from the central station for acknowledging the first test signal, alerting, by the remote device, a user of the remote device about a failure of the network connection.
