Dual-Link Status Reporting for Communication Link Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices rely on single-mode communication links for detecting and reporting status, which can fail to transmit abnormal status to the backend server if the link becomes abnormal, preventing immediate recovery commands.
Innovation Solution
Implementing a dual-mode communication system with LPWAN and LR-WPAN links to ensure continuous status reporting, allowing automatic switching to a secondary communication link when the primary link fails, enabling recovery through a backup control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-mode communication link is used for detecting and status reporting, then the device complexity is reduced, but the reliability of status reporting deteriorates when the communication link becomes abnormal
Solution Approach 1:
The system changes the communication mode parameter from single-mode to dual-mode, allowing switching between LPWAN and LR-WPANs communication specifications. When the primary LPWAN link becomes abnormal, the system transitions to using the secondary LR-WPAN link for status reporting, thereby maintaining reliability without significantly increasing overall system complexity
Solution Approach 2:
A gateway device serves as an intermediary between the electronic device and the backend server. The gateway receives status reports from the electronic device via LPWAN or LR-WPANs, forwards them to the backend server, and can also issue recovery commands back to the electronic device, ensuring continuous communication even when direct links fail
2Ease of operation
If a single-mode communication link is used, then the ease of operation is improved, but the loss of time for recovery commands increases when communication fails
Solution Approach 1:
The system establishes a dual-mode communication link in advance, with both LPWAN and LR-WPANs links configured and ready. When the primary communication link fails, the system can immediately switch to the pre-configured secondary link without delay, reducing the time loss for transmitting recovery commands

AI summary
A detecting and status reporting system, includes a first control device and at least one second control device. The first control device sends a first message to a remote device through a first communication link. The first communication specification of the first communication link is LPWAN (Low-Power Wide-Area Network). The at least one second control device communicates with the remote device through the first communication link, and communicates with the first control device through a second communication link. The second communication specification of the second communication link is LR-WPANs (Low-Rate Wireless Personal Area Networks). When the first communication link of the first control device is abnormal, the first control device sends the first message to the at least one second control device through the second communication link, and sends the first message to the remote device through the first communication link of the at least one second control device.
