Dual-Mode Communication Device Startup Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication systems, differences in startup timing between communication devices can lead to false detection of optical communication errors, as a device that has not fully started may not receive an optical signal from another device that has already begun, causing misinterpretation of signal loss.
Innovation Solution
A communication device with both optical and electro-communication capabilities, including a control circuit that transmits error information only after confirming the status of the other device through electric signals, uses a detection stop setting to prevent false alarms during startup and enables optical communication once both devices are synchronized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If optical communication is initiated at startup, then communication speed is improved, but false detection of communication errors occurs due to timing differences
Solution Approach 1:
The patent applies preliminary action by performing electro-communication before optical communication during the startup phase. The control circuit first establishes electrical connection and confirms the other communication device is ready, then initiates optical communication. This preliminary electro-communication handshake prevents false error detections by ensuring both devices are synchronized and ready before optical signals are exchanged.
2Adaptability or versatility
If startup timing is unsynchronized, then device independence is maintained, but optical signal reception fails due to timing mismatch
Solution Approach 1:
The patent implements feedback through a two-way electro-communication handshake protocol. Each device sends a startup notification signal and waits for confirmation from the other device before initiating optical communication. This feedback mechanism allows devices to maintain independence in their startup timing while ensuring synchronization when optical communication begins, preventing signal reception failures.

AI summary
A communication device includes: an optical-communication circuit that is capable of performing optical communication with a different communication device and transmits a first electric signal to the different communication device at a startup time of the communication device; an electro-communication circuit that is capable of performing electro communication with the different communication device and receives a second electric signal transmitted from the different communication device in response to the first electric signal; and a control circuit that transmits error information indicating an error in the optical communication to a device after the second electric signal is received by the electro-communication circuit.
