Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical settings, portable radiation image capturing devices face data communication challenges due to interference from other wireless terminals, which can disrupt wireless LAN communication, limiting the availability of usable channels and affecting communication speed and signal quality.
Innovation Solution
A data communication system that includes a channel determination section which calculates an influence score for each channel based on interfering radio wave strength, classifying it into zones and assigning higher scores for more difficult transmission conditions, allowing the selection of the channel with the smallest score for wireless communication between the radiation image capturing device and the access point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless LAN communication is used for data transmission between the radiation image capturing device and external devices, then ease of operation and configuration simplicity are improved, but communication reliability deteriorates due to interference from other wireless terminals
Solution Approach 1:
The system performs preliminary channel quality assessment and interference detection before establishing data transmission. The channel determination section evaluates multiple channels in advance, calculates influence rates from interfering radio waves, and pre-selects the optimal channel with the least interference, ensuring reliable communication from the start
Solution Approach 2:
The system continuously monitors wireless communication environments and adjusts channel selection based on real-time feedback. The channel determination section receives information about interfering radio waves, calculates their influence rates, and dynamically determines the best channel for data transmission, creating a closed-loop control system that adapts to changing conditions
2Reliability
If channel selection is performed to avoid interfering radio waves, then communication reliability is improved, but device complexity increases due to the need for channel determination and interference analysis
Solution Approach 1:
The channel determination section is integrated directly into the wireless communication section, allowing the system to autonomously perform channel quality assessment and interference analysis without requiring external control systems. The system self-determines the optimal channel based on its own reception of interfering radio wave information, reducing overall device complexity
Solution Approach 2:
The channel determination section combines multiple functions including interference detection, influence rate calculation, and optimal channel selection into a single integrated component. By merging these previously separate functions, the system reduces complexity while maintaining reliable communication through intelligent channel selection

AI summary
A data communication system and a radiation image capturing system are described. According to one implementation, a data communication system includes a wireless terminal; an access point; and a channel determination section. The channel determination section carries out calculation processing for calculating an influence rate as a score for each of a plurality of channels, and determines a channel having the smallest calculated score to be a channel used, and classifies the influence rate by the interfering radio wave into a plurality of zones, sets the score in each of the zones so that the value of the score is higher as transmission/receiving of the data between the wireless terminal and the access point of the system becomes more difficult when the interfering radio wave having the strength of the zone exists, adds the scores of each zone, and calculates the score.
