Communication Device Reset Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems with multiple communication modes face inefficiencies in quickly resuming communication after a reset, particularly due to the need to confirm compatible communication formats, leading to time-consuming re-establishment of connections.
Innovation Solution
A communication device that includes means to automatically switch between first and second communication modes based on reset causes, using a communication control mechanism to resume communication using the second mode if acceptable, and switching to the first mode if the second mode is not supported, thereby minimizing downtime.

Engineering Contradiction Analysis
1Reliability
If communication format confirmation processing is executed upon system start-up to ensure compatible communication, then communication reliability is improved, but communication establishment time increases
Solution Approach 1:
The communication format confirmation processing is executed in advance during system start-up before actual communication begins. This preliminary action ensures that the communication format is confirmed to be compatible between devices, so that when communication is subsequently reset, the devices can quickly resume using the pre-confirmed format without time-consuming reconfirmation, thus resolving the contradiction between reliability and time loss.
2Adaptability or versatility
If multiple communication lines with differing capabilities are used to transmit data, then communication flexibility is improved, but transmission performance deteriorates due to data passing-over
Solution Approach 1:
The communication system segments data transmission by communication line capability. Transmission data is divided into a first series for high-speed lines and a second series for normal-speed lines, with each series transmitted through appropriate communication lines. This segmentation prevents data passing-over between lines with differing capabilities, maintaining transmission performance while preserving the flexibility to use multiple communication lines simultaneously.

AI summary
In a communication device, a communicator communicates with a communication counterpart using a first communication mode or a second communication mode. When a communication by the communicator with the communication counterpart using the second communication mode is reset due to a first cause, if the communication with the communication counterpart using the second communication mode is acceptable, a communication controller causes the communicator to resume communication with the communication counterpart using the second communication mode, and if the communication with the communication counterpart using the second communication mode is unacceptable, the communication controller causes the communicator to start a communication with the communication counterpart using the first communication mode. When the communication by the communicator with the communication counterpart using the second communication mode is reset due to a second cause, the communication controller causes the communicator to resume communication with the communication counterpart using the second communication mode.
