Solution Overview
Problem
In bus-connected communication systems, the sharing of communication lines between host and client sides leads to deteriorated communication quality when multiple sensor units are connected in sequence.
Innovation Solution
A sensor unit with a control unit that includes separate host and client communication control units, along with a circuit power supply generation part, to manage communication and power independently for each sensor unit, connected via communication cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple sensor units are connected in sequence via bus connection, then the quantity of connected devices increases, but communication quality deteriorates
Solution Approach 1:
The communication control unit is divided into separate host communication control unit and client communication control unit. This segmentation allows independent communication channels for host-device and client-device interactions, preventing signal interference and quality degradation that occurs in shared bus connections when multiple sensor units are connected in sequence.
2Reliability
If separate host and client communication control units are implemented, then communication quality is maintained, but device complexity increases
Solution Approach 1:
The control unit is designed with multi-functional capability, integrating both host communication control unit and client communication control unit within a single control unit structure. This allows the same control unit to handle multiple communication roles (host and client) depending on the operational context, maintaining communication quality while avoiding the need for completely separate control units for each function.
