Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in continuously specifying moving distance correlation values due to interruptions caused by wireless communication collisions, particularly when acquiring GPS distance data from external devices.
Innovation Solution
A communication device equipped with a wireless communication receiver and a processor that acquires first information on moving distance through GPS data and specifies a moving distance correlation value. In cases where a predetermined condition of communication collision is met, the processor switches to using acceleration sensor data to specify the moving distance correlation value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device continuously acquires moving distance information from external devices via wireless communication, then the moving distance correlation value can be specified in real-time, but the acquisition may be interrupted by communication collisions
Solution Approach 1:
The patent introduces an acceleration sensor as an intermediary device to acquire moving distance information independently of wireless communication. When communication collision interrupts the acquisition of moving distance information from external devices, the acceleration sensor serves as a mediator to continue specifying the moving distance correlation value based on acceleration data, thus maintaining continuous operation without time loss.
2Reliability
If the device uses acceleration sensor data to specify moving distance correlation value during communication interruption, then continuous specification is maintained, but the measurement precision may be affected
Solution Approach 1:
The patent applies parameter changes by switching between different data sources (GPS position data from external devices and acceleration sensor data from the device itself) based on communication status. When communication is normal, high-precision GPS data is used. When communication collision occurs, the system switches to acceleration sensor data, adjusting the measurement parameter to maintain continuity while accepting temporary precision trade-offs.

AI summary
Provided is a communication device that includes a wireless communication receiver that performs, with an external device, a first wireless communication for acquiring first information concerning a moving distance of the communication device and a second wireless communication that possibly has collision with the first wireless communication, and a processor that specifies a moving distance correlation value related to the moving distance. The processor acquires an acceleration of the communication device, specifies the moving distance correlation value based on the first information that the wireless communication receiver acquires from the external device, and specifies the moving distance correlation value based on the acceleration of the communication device in a case determining that a first condition is present. In the first condition, acquisition of the first information from the external device is possibly interrupted by the collision more than predetermined.
