Wireless Device Identification Switching via Cable Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the unstable connection between mobile devices and wireless access points due to environmental factors like movement leads to interruptions in data transmission, as existing solutions require several seconds to switch between devices, causing data interruptions.
Innovation Solution
A wireless communication system that automatically switches device identifications by using a cable network interface to connect multiple devices, a protocol processing module to swap messages and select main and backup devices based on connection time, and an activity processing module to record and transmit IP and MAC addresses, ensuring rapid reconnection when the main device fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple work devices are disposed on the carrier to provide redundancy, then the wireless network stability is improved, but the data transmission interruption time increases to several seconds
Solution Approach 1:
The patent applies preliminary action by having the main device continuously transmit survival messages through the cable network before actual failure occurs. Backup devices monitor these messages in advance, so when the main device fails, the backup devices are already prepared and can immediately take over without several seconds of interruption. This pre-positioning of monitoring and preparedness resolves the contradiction between reliability and time loss.
Solution Approach 2:
The patent introduces the cable network as an intermediary communication channel between main and backup devices. Instead of relying solely on wireless communication which is unstable on mobile carriers, the cable network provides a stable intermediate path for transmitting survival messages and coordination data. This intermediary enables rapid detection and switching, reducing data interruption time while maintaining network stability.
2Speed
If the main device continuously transmits survival messages through the cable network, then the switching speed is improved to less than 250 microseconds, but the system complexity increases
Solution Approach 1:
The patent applies universality by making the cable network serve multiple functions: it is used for both data transmission and for transmitting survival messages for monitoring. The same cable infrastructure that carries work data also carries the survival messages, eliminating the need for separate dedicated monitoring channels. This multi-functionality achieves rapid switching speed without proportionally increasing system complexity.
Solution Approach 2:
The system applies self-service by having backup devices automatically monitor survival messages and automatically switch to main device functionality when failure is detected. The protocol processing modules autonomously determine failure conditions and execute switching without requiring external intervention or complex centralized control systems. This self-service approach enables fast switching while keeping the control architecture relatively simple.

AI summary
A wireless communication system and methods for automatically switching device identifications are disclosed, where the device identifications are automatically determined by a plurality of work devices connected to a cable network after a connection time, respectively, and the one among the plurality of work devices becomes a main device may transmit a survive message to the work devices becoming a backup device, and the main device is determined as failing to work normally and a new main device is automatically determined again when the backup device fails to receive the survive message transmitted by the main device or a switch notification transmitted by the main device, so that the wireless communication on a carrier may have an improved stability and the technical efficacy may be achieved that the work device may automatically and rapidly determine the main device when no main device existing in the wireless network environment.
