Bus Node Signal Processing System for Protocol Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal processing systems in bus nodes require complex signal conditioning modules to adapt incoming signals from external components to both internal and external bus protocols, leading to increased hardware and software complexity and the need for multiple configurations for different external components.
Innovation Solution
The signal processing system transfers raw data processing from signal conditioning modules to the bus node, simplifying the modules' role to only condition signals for internal bus transmission, allowing for reduced hardware capacity and potentially eliminating the need for different software configurations, as the bus node processes the signals and generates output signals directly for internal or external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If signal conditioning modules adapt incoming signals to both internal and external bus protocols, then signal compatibility is improved, but device complexity increases
Solution Approach 1:
The patent divides the signal processing function into two separate components: the signal conditioning module that only conditions signals for internal bus transmission, and the bus node that handles protocol conversion to both internal and external bus protocols. This segmentation resolves the contradiction by eliminating the need for the signal conditioning module to handle multiple protocol adaptations, thereby reducing its complexity while maintaining signal compatibility through the bus node's dedicated protocol handling capability.
2Adaptability or versatility
If multiple software configurations are provided for different external components, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The bus node is designed with universal protocol conversion capability that can handle multiple external bus protocols (such as Profibus, Fieldbus, Ethernet) through a single integrated unit. This multi-functional design eliminates the need for multiple software configurations in signal conditioning modules for different external components, as the bus node universally manages all protocol adaptations, thereby improving ease of operation while maintaining broad component compatibility.
3Productivity
If raw data processing is performed in signal conditioning modules, then processing capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the raw data processing function from the signal conditioning module and relocates it to the bus node. The signal conditioning module is simplified to perform only signal conditioning and analog-to-digital conversion, while the bus node handles the computationally intensive raw data processing, protocol conversion, and signal generation. This extraction resolves the contradiction by maintaining signal processing capability at the bus node level while significantly reducing the hardware capacity and complexity requirements of the signal conditioning modules.

AI summary
A signal processing system having a bus node, which is designed for signal conversion between signals of an internal and an external bus system and in each case includes at least one interface to be coupled to the external bus system and to the internal bus system, and having at least one signal conditioning module, which is designed for physical conditioning and/or analog/digital conversion for signals from an external component and includes an interface for an internal bus system and at least one connection for the external component and is connected to the bus note via the internal bus system. The bus node is designed for internal raw data processing of the signals provided by the signal conditioning module and to output at least one output signal dependent on the processed signals to the internal and/or to the external bus system.
