Wireless Relay Data Transmission Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission in wireless systems, particularly in remote control systems for home appliances, lacks reliability due to the inability of servers to determine if state information is lost during internet transmission.
Innovation Solution
A method where the relay device connects to a server, determines if state information is stored, and sends it if available, or sends interactive commands to notify the server of data issues, allowing the server to interrupt the connection and ensuring reliable data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the relay device only sends state information to the server when data is available, then data transmission efficiency is improved, but the server cannot determine whether data loss occurred during transmission
Solution Approach 1:
The patent implements a feedback mechanism where the relay device sends interactive commands to the server to confirm data reception status. The server responds with acknowledgment messages, creating a closed-loop feedback system that enables the relay device to determine whether state information was successfully received, thereby resolving the reliability issue while maintaining transmission efficiency
Solution Approach 2:
The patent employs preliminary action by having the relay device send interactive commands before actually transmitting state information. This preliminary interaction establishes communication channels and confirms server readiness, allowing the system to efficiently determine data loss occurrence without compromising overall transmission efficiency
2Reliability
If the relay device sends interactive commands to the server, then the server can determine data transmission status, but additional communication overhead is introduced
Solution Approach 1:
The patent implements periodic action by having the relay device send interactive commands at regular intervals or at specific trigger points in the communication process. This periodic interaction ensures reliable data transmission status determination while minimizing unnecessary communication overhead by spacing out the interactive commands appropriately

AI summary
A method for transmitting data in a wireless system, wherein the wireless system includes a server, a relay device, and at least one appliance. The method includes that the relay device is connected to the server through an internet; determine whether there is a state information sent from the appliance being stored in the relay device; if so, send the state information to the server; otherwise, send a first interactive command to the server, wherein the first interactive command corresponds to a situation that there is no state information being stored in the relay device; send a second interactive command to the server, and then interrupt a connection with the server, wherein the second interactive command requests the server to interrupt a connection with the relay device. Whereby, the server could determine whether the relay device transmits data normally or not, ensuring the reliability of data transmission.
