Intermediation Device for Collision-Free Data Transfer in Cyclic Telecommunication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cyclic data transfer systems face collisions when integrating with general-purpose networks that have non-cyclic message communication, especially under high load conditions, as external messages may not align with the predetermined time slots of the cyclic communication, leading to frequent disturbances in internal data transfer.
Innovation Solution
An intermediation device monitors cyclic communication patterns to determine expected occurrence time slots, allowing external messages to be transmitted without colliding with cyclic messages by buffering and synchronizing them with the cyclic communication, thereby minimizing disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external messages are transferred directly to the cyclic telecommunication system, then the system can accept messages from general-purpose networks, but message collisions occur frequently disturbing internal data transfer
Solution Approach 1:
The intermediation device performs preliminary actions by monitoring cyclic communication patterns in advance and determining expected occurrence time slots before external messages are transmitted. This allows the system to prepare time slot allocations for external messages that avoid collision with internal cyclic messages, thereby maintaining reliability while accepting external communication.
Solution Approach 2:
An intermediation device is introduced between general-purpose networks and the cyclic telecommunication system. This intermediary monitors cyclic communication patterns, determines safe transmission time slots for external messages, and coordinates transmission to avoid collisions. The intermediary enables external message acceptance without disturbing internal data transfer reliability.
2Productivity
If the number of external messages is increased, then the system can handle more communication load, but the average number of collisions increases disturbing internal data transfer
Solution Approach 1:
The system dynamically determines expected occurrence time slots based on monitored cyclic communication patterns. The intermediation device adjusts time slot allocations dynamically according to the actual cyclic message timing, allowing the system to accommodate varying numbers of external messages without causing collisions that would disturb internal data transfer integrity.
3Device complexity
If external messages are transmitted without time slot reservation, then the system remains simple, but collisions occur when cycle times are short and load is high
Solution Approach 1:
The intermediation device continuously monitors cyclic communication patterns and uses this feedback to determine expected occurrence time slots for external messages. This feedback mechanism allows the system to automatically adjust time slot allocations to avoid collisions, managing complexity while eliminating harmful collision disturbances even under high load conditions.
