Solution Overview
Problem
Existing wireless communication systems for vehicles face challenges in efficiently transmitting big data without interfering with real-time user data communications, particularly in managing communication quality and load distribution across varying positions and times.
Innovation Solution
A wireless communication apparatus that transmits position information to a server, which provides communication quality information, allowing the apparatus to specify optimal communication positions and switch between different communication services based on data priority and congestion, ensuring efficient data transmission for big data without disrupting user data communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If big data is transmitted using wireless communication apparatus, then data collection for big data is achieved, but communication quality deteriorates due to increased communication load
Solution Approach 1:
The system performs preliminary actions by transmitting position information in advance and receiving communication quality information before actual data transmission. This allows the mobile body to pre-select optimal communication positions and times, ensuring big data transmission does not degrade real-time communication quality
Solution Approach 2:
The communication system is segmented into different service types: real-time user data communication and non-real-time big data transmission. By separating these services and applying different transmission strategies (immediate transmission vs. scheduled transmission at optimal positions), the system prevents big data from interfering with real-time communication quality
2Adaptability or versatility
If data transmission is performed at any position, then transmission flexibility is maintained, but communication load concentrates causing quality degradation
Solution Approach 1:
The system implements feedback by having the server apparatus transmit communication quality information back to the mobile body based on received position information. This feedback loop enables the mobile body to adapt its transmission strategy, selecting positions with lower communication load and better quality, thus distributing load across the network
Solution Approach 2:
The transmission position and timing are made dynamic rather than fixed. The mobile body continuously receives communication quality information for different positions and dynamically selects optimal transmission points, allowing the system to adapt to changing network conditions and distribute communication load effectively
3Reliability
If communication quality information is used to specify transmission position, then communication quality improves, but system complexity increases
Solution Approach 1:
The transmitter and receiver units serve multiple functions: they handle both real-time user data communication and non-real-time big data transmission scheduling. By making these components multi-functional, the system improves communication quality without requiring entirely separate dedicated systems, thus limiting complexity increase

AI summary
A wireless communication apparatus mounted on a mobile body includes a transmitter and a receiver. The transmitter is configured to transmit position information indicating a position to which the mobile body is scheduled to move, to a server apparatus. The receiver is configured to receive communication quality information indicating a communication quality corresponding to the position, from the server apparatus. The transmitter is configured to transmit the date at a communication position specified based on the communication quality information.
