Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in automation face challenges in efficiently transmitting signals over varying distances without the need for complex and costly adaptation measures, particularly in plug-in and cable-connected configurations, which can lead to signal interference and unreliable communication.
Innovation Solution
The communication participant features two identically designed communication interfaces with receiving and transmitting modules that can adapt signal levels and operate effectively over both short and long distances, using electromechanical plug-in connectors and multicore connecting cables, along with a communication processor and computing unit to manage and process signals, ensuring reliable and interference-free communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication interfaces are designed differently for plug-in and cable connections, then communication reliability for each connection type is optimized, but device complexity increases
Solution Approach 1:
The communication interface is designed with universal functionality to handle both plug-in connected and cable connected communication participants using the same hardware structure. The receiving module and transmitting module are configured to automatically adapt to different connection types without requiring physically different interfaces, thereby maintaining communication reliability while reducing device complexity.
Solution Approach 2:
The communication interface dynamically adjusts communication parameters such as signal level and transmission characteristics based on the detected connection type (plug-in or cable). This parameter adaptation allows the same hardware interface to optimize performance for different connection scenarios without increasing structural complexity.
2Reliability
If additional components are added to adapt signal levels for different connection types, then communication integrity is maintained, but device complexity and cost increase
Solution Approach 1:
The communication interface performs self-adaptation by automatically detecting the connection type and adjusting its signal transmission characteristics without requiring external adaptation components. The receiving module and transmitting module work together to self-regulate signal levels, eliminating the need for additional adaptors or converters.
Solution Approach 2:
The communication interface employs dynamic signal level adjustment based on the detected connection type. The transmitting module modifies its output signal characteristics in real-time according to whether it is connected via plug-in or cable, allowing the system to maintain communication integrity through software-controlled adaptation rather than hardware additions.
3Length of stationary object
If signal level is increased for long-distance cable connections, then transmission range is extended, but signal interference increases
Solution Approach 1:
The transmitting module dynamically adjusts the signal level parameter based on the detected connection type and distance. For cable-connected remote participants, the signal level is increased appropriately to extend transmission range, while for plug-in connected participants, the signal level is reduced to minimize interference. This selective parameter adjustment resolves the contradiction between transmission distance and signal interference.
