Wireless Relay Device Data Transmission Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless data transmission systems in home appliance control systems lack reliability, particularly in determining whether data is lost during Internet transmission, leading to confusion and inefficiency.
Innovation Solution
A method involving a relay device that connects to a first server through a network, determines if state information from appliances is stored, and sends this information or interactive commands to ensure data integrity, allowing the first server to assess data transmission reliability and enabling individual communication with the relay device and data processing by a second server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the relay device sends state information to the first server through the Internet, then the system can collect appliance data remotely, but the first server cannot determine whether the relay device sends the state information or not when data is lost in transmission
Solution Approach 1:
The patent implements a feedback mechanism where the relay device sends interactive commands to the first server to confirm data transmission status. The server responds with acknowledgments, creating a closed-loop communication system that allows verification of whether state information was successfully received, thereby resolving the inability to determine transmission success in conventional systems.
Solution Approach 2:
The patent introduces an intermediary verification process where the first server acts as a mediator to confirm receipt of state information from the relay device. This intermediary layer provides a reliable confirmation mechanism that bridges the gap between data sending and data reception verification, solving the problem of uncertain transmission status.
2Reliability
If the relay device continuously connects to the first server to ensure data transmission reliability, then transmission status can be verified, but system complexity and communication overhead increase
Solution Approach 1:
The patent employs periodic interactive commands where the relay device sends verification requests at specific intervals rather than continuously maintaining a connection. This periodic action allows the system to verify data transmission reliability while reducing communication overhead and system complexity compared to continuous connection mechanisms.

AI summary
A method for transmitting data in a wireless system, wherein the wireless system includes a first server, a second server, a relay device, and at least one appliance. The method includes that the relay device is connected to the first server through a network; determine whether the relay device stores a state information sent from the appliance; if so, send the state information to the first server; otherwise, send a first interactive command to the first server; receive a data sent from the relay device by the first server, and transmit it to the second server for subsequent process; the relay device sends a second interactive command to the first server, and then interrupt a connection with the first server. Whereby, the first server could determine whether the relay device transmits data normally or not by individually communicating with the relay device, ensuring the reliability of data transmission.
