Alert Device with Local Time Storage for Vehicle Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small-sized portable terminals for vehicle notification, such as drones, face accuracy issues in alerts due to deteriorating communication quality with control devices.
Innovation Solution
An alert device equipped with a communication circuit to receive time information related to vehicles, a storage unit to store this information, and alertors to execute alerts based on the stored time information, ensuring accurate alerts even when communication quality decreases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the alert device continuously receives time information from the control device, then the alert accuracy is maintained, but the communication dependency increases and alert accuracy decreases when communication quality deteriorates
Solution Approach 1:
The alert device stores time information received from the control device in advance in its storage unit. This preliminary action ensures that even when communication quality deteriorates and real-time updates are unavailable, the device can continue to execute alerts based on the stored time information, thereby maintaining alert accuracy while reducing communication dependency.
2Measurement precision
If the alert device uses real-time communication to update alert timing, then the alert accuracy is improved, but the alert accuracy decreases when communication quality is lowered
Solution Approach 1:
The alert device creates a local copy of the time information received from the control device and stores it in its storage unit. This copying mechanism allows the device to execute alerts based on the stored copy even when real-time communication is unavailable or of poor quality, ensuring that alert timing accuracy is maintained without being dependent on continuous high-quality communication.
3Reliability
If the alert device stores time information locally, then the alert can be executed independently of communication quality, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential time information from the communication data and stores it locally in a simplified manner. By taking out only the necessary time parameters rather than storing complete communication protocols or large datasets, the device achieves independent alert execution while minimizing the increase in device complexity.
Data Source
AI summary
An alert device includes a data communication circuit configured to receive, from an alert control device, time information representing a vehicle-related time that is a time relating to a vehicle. The alert device also includes a storer that is a memory or a storage device, the storer being configured to store the received time information, and an alertor configured to execute an alert relating to the vehicle, based on the vehicle-related time represented by the stored time information.
