Directional Station Selection for Faster Sound Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems require users to manually search through a list of stations to find a target station for sound communication, consuming time and effort.
Innovation Solution
A communication apparatus that includes an acquisition unit for position and direction information, a storage unit for further station data, and a search unit to automatically identify and set the sound communication frequency of a target station based on direction and responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual search through station list is used to find target station, then user can find target station in specific direction, but much time and effort are consumed
Solution Approach 1:
The system pre-acquires and stores direction information for each station in the station list before the user needs to search. This preliminary preparation allows the search unit to quickly match the user's current direction with pre-stored station directions, eliminating the need for manual searching and significantly reducing the time to find a target station while maintaining directional accuracy
2Reliability
If manual search through station list is used to find target station, then user can identify responsive stations, but much time and effort are consumed
Solution Approach 1:
The system automatically verifies station responsiveness by having stations transmit their own direction and status information. The search unit then automatically matches this information with the user's current direction and responsiveness requirements, enabling the system to self-identify suitable target stations without manual intervention, thus maintaining reliability while reducing time consumption
3Loss of time
If automatic target station determination is implemented, then time and effort are reduced, but system complexity increases
Solution Approach 1:
The search unit is designed as a multi-functional component that performs multiple tasks: acquiring station information, filtering responsive stations, matching directional information, and determining target stations. By consolidating these functions into a single versatile unit, the system achieves automatic target station determination that reduces time and effort while minimizing the increase in overall system complexity

AI summary
In a wireless communication apparatus, an acquisition unit acquires user's station position information, user's station direction information, further station position information, and further station information. A storage unit stores the further station information and reception time information in association with each other in a further station information list. A search unit searches the further station information list for candidates of a target station located in a direction of the user's station and capable of responding, based on the user's station position information and the user's station direction information, and determines a target station to communicate with by sound from among the candidates of a target station based on at least one of a distance from the user's station to a candidate of a target station retrieved by a search or a time of reception from the candidate of a target station.
