Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical-technical systems, such as CT systems, face challenges in transmitting both hardware signals and data efficiently due to the use of separate protocols and networks, which complicates system improvements and expansions, and requires a solution for achieving high Quality of Service (QoS) in real-time data transmission.
Innovation Solution
A method and network that merge data and digitized signals into cells with a header containing connection information, allowing synchronous transfer via switching stations, enabling independent and high-speed transmission of both hardware signals and data, with the ability to adjust cell length and insert fill characters for synchronization, ensuring precise predictability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate transmission technologies are used for hardware signals and data, then high QoS can be achieved for signal transmission, but the system complexity increases and future expansion becomes difficult
Solution Approach 1:
The patent combines separate hardware signal transmission and data transmission into a unified cell-based transmission system. Both signals and data are packaged into cells with appropriate priorities, allowing them to share the same transmission medium while maintaining distinct QoS requirements. This merging eliminates the need for separate transmission technologies and reduces system complexity.
Solution Approach 2:
The transmission system is designed to handle multiple types of traffic (hardware signals and data) through a universal cell structure. The cell format can accommodate different payload types, and the switching stations can route different cell types through appropriate paths, providing multi-functional capability within a single transmission infrastructure.
2Reliability
If separate connection lines are used for control signals and data, then high QoS is achieved, but the number of connections increases and cost expenditure rises
Solution Approach 1:
The patent merges control signals and data into the same physical transmission medium by packaging both into cells. The switching stations use priority mechanisms to ensure control signals receive appropriate QoS treatment while sharing the transmission infrastructure with data, thereby reducing the total number of physical connections required.
Solution Approach 2:
The transmission medium is segmented into time slots or priority queues within the cell structure, allowing control signals and data to be multiplexed on the same physical connection. This segmentation enables multiple logical channels to coexist on a single physical medium, reducing the quantity of physical connections needed.
3Reliability
If synchronous transmission is used for cells, then high QoS and real-time requirements are met, but the transmission infrastructure becomes more complex
Solution Approach 1:
The patent implements synchronous transmission by organizing cell transmission into periodic frames with fixed time slots. Each cell type is assigned specific time slots within the periodic frame structure, ensuring deterministic transmission timing and meeting real-time requirements while using standard synchronous transmission mechanisms.

AI summary
In a method and network for transferring data and signals between terminal equipment via one or more switching stations, the data and digitized signals are combined in cells, with each cell having a header in which connection information is contained that designates a transmission or routing target. The terminal equipment and switching stations are synchronized so that the cells are transferred in a synchronized manner via one or more switching stations. Signals and high quality of service (QoS) data thus can be transferred through the same network.
