Mesh Network Withdrawal Control via Secondary Wireless Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identifying and causing communication devices to withdraw from a mesh network is time-consuming and inefficient in existing systems.
Innovation Solution
A communication system and control terminal that utilize a second wireless communication mode to transmit withdrawal request signals via a mesh network, allowing devices to withdraw without direct connection, and store identification information of failed devices for subsequent direct connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control terminal directly connects to each communication device to transmit withdrawal request signals, then the withdrawal process is reliable, but the time and effort required increases significantly
Solution Approach 1:
The patent introduces a mesh network as an intermediary communication channel. Instead of direct connection between control terminal and each device, the withdrawal request signal is transmitted through the mesh network infrastructure, which relays the signal to multiple devices simultaneously. This mediator approach maintains reliable delivery while eliminating the time-consuming one-by-one connection process.
Solution Approach 2:
The patent combines multiple withdrawal request transmissions into a single mesh network broadcast. By merging the communication path and using the mesh network's inherent routing capabilities, the system can initiate withdrawal for multiple devices through one control action, rather than requiring separate direct connections for each device.
2Ease of operation
If the control terminal connects to each device individually in the second wireless communication mode, then precise control is achieved, but the operational complexity increases
Solution Approach 1:
The mesh network acts as an intermediary that simplifies the control terminal's operation. The control terminal only needs to send a single withdrawal request through the mesh network, rather than managing multiple individual connections. This mediator reduces the operational steps required while the mesh network's routing protocols ensure the signal reaches all intended devices.
Solution Approach 2:
The mesh network performs self-service by automatically routing and delivering the withdrawal request signal to the appropriate devices. The network's existing routing infrastructure handles the complex task of identifying and reaching multiple devices without requiring the control terminal to manage each connection individually, thus reducing operational complexity.

AI summary
A communication system and the like which can cause a communication device to more easily withdraw from a mesh network are provided. The communication system includes: a plurality of devices that form a mesh network, and perform wireless communication in a first wireless communication mode in the mesh network; and a control terminal, the control terminal: connects to a first device among the plurality of devices by wireless communication in a second wireless communication mode different from the first wireless communication mode; and transmits, to the first device, a withdrawal request signal for causing a second device different from the first device among the plurality of devices to withdraw from the mesh network, and when the second device receives the withdrawal request signal from the first device via the mesh network, the second device withdraws from the mesh network.
