Engineering Contradiction Analysis
1Reliability
If the time-out period is set based on fixed device layout and initial communication configuration, then the communication control is simple, but the communication fails when device layout changes or CPU load varies
Solution Approach 1:
The system dynamically adjusts the time-out period based on real-time detection of device layout and CPU processing load. The control apparatus changes communication parameters adaptively rather than using fixed settings, allowing the time-out period to respond to varying system conditions and maintain reliable communication.
Solution Approach 2:
The control apparatus detects device layout and CPU load conditions, then uses this feedback information to adjust the time-out period. This closed-loop control ensures that communication parameters are optimized based on actual system state, preventing communication failures while adapting to changes.
2Adaptability or versatility
If communication converters are added to extend transmission distance and capacity, then the system flexibility and layout options increase, but the communication delay increases and time-out control becomes more difficult
Solution Approach 1:
The system dynamically determines the time-out period based on the actual number and type of communication converters in the transmission path. When converters are added to extend layout flexibility, the system automatically adjusts the time-out period to account for the increased communication delay, maintaining reliable communication.
Solution Approach 2:
The control apparatus preliminarily identifies the types and numbers of communication converters in the transmission pathway before establishing communication. This advance knowledge allows the system to pre-calculate the appropriate time-out period, preventing communication timeouts caused by excessive delay from multiple converters.

AI summary
A system controller has a layered structure including an application layer, an intermediate layer, and a physical layer. The application layer includes a GUI display section and an operation input processing section for controlling the user interface unit used by the user. The application layer further includes a data control section for controlling an entire system and a communication processing section for executing the communication with the intermediate layer. The communication processing section executes communications with the intermediate layer and the physical layer based on the TO value stored in the TO value storage section. Even if a plurality of the communication transmission pathways are employed, a plurality of medical devices may be controlled in the optimum and stable manner.
