IoT Electronic Apparatus Server Access Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT systems, electronic apparatuses face inefficiencies in power consumption and channel contention due to continuous attempts to access a non-responsive server, leading to communication congestion and unnecessary power usage.
Innovation Solution
The electronic apparatuses implement multiple operation modes, where if the server does not respond, a signal is transmitted to restrict access, reducing the frequency of attempts and conserving power by switching to a second mode that limits server access until the server becomes responsive again.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic apparatuses continuously attempt to access the server, then communication reliability is maintained, but power consumption increases and channel contention occurs
Solution Approach 1:
The system dynamically switches between first operation mode (normal access) and second operation mode (restricted access) based on server responsiveness. When the server fails to respond, the apparatus transitions to the second mode to reduce power consumption while maintaining the ability to resume normal operation when the server becomes responsive again.
Solution Approach 2:
The system changes the access parameter (access frequency/restriction level) based on server response status. In the first mode, normal access parameters are used, while in the second mode, access parameters are modified to restrict attempts, thereby reducing power consumption during server unavailability.
2Reliability
If electronic apparatuses continuously attempt to access the server, then communication reliability is maintained, but channel contention increases
Solution Approach 1:
The system dynamically adjusts channel access behavior based on server responsiveness. When the server is unresponsive, the apparatus switches to the second operation mode that restricts access attempts, thereby reducing channel contention and improving overall channel occupation efficiency while maintaining the capability to restore normal access when the server recovers.
3Use of energy by moving object
If access restriction is implemented when server is unresponsive, then power consumption is reduced, but communication responsiveness may be delayed
Solution Approach 1:
The system implements periodic access attempts in the second operation mode rather than continuous attempts. This allows the apparatus to conserve power by restricting access during server unavailability while still periodically checking for server recovery, thus balancing power consumption with the need to resume communication when the server becomes responsive.

AI summary
An example electronic apparatus includes an information generator configured to generate information used to one function of a user terminal, a communicator configured to communicate with the user terminal, the server and a plurality of external apparatuses having a plurality of operation modes, and a controller configured to control the communicator: to attempt an access to the server at a first operation mode; in response to determining that the server is in a normal communication state based on the access attempt, to provide information generated by the information generator to the user terminal via the server; and in response to determining that the server is in a communication pending state based on the access attempt, to transmit a first mode changing signal for operating in a second operation mode, which restricts the access to the server, to at least one of the plurality of external apparatuses.
