Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require relicensing and time-consuming software updates to change process data transmitted between rail vehicles and static control points, leading to inefficiencies and high costs.
Innovation Solution
A configurable arrangement with a rail vehicle and static control point that allows process data transmission through a control unit and diagnosis server, utilizing configurable bus-oriented and function-based processing, enabling changes without software relicensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If process data are changed on the rail vehicle, then the system becomes more adaptable to new requirements, but software relicensing and reinstallation are required which increases time and cost
Solution Approach 1:
The system separates the process data configuration from the core software licensing. The control unit contains a configurable data processing section that can be independently configured without requiring software changes or relicensing. This segmentation allows process data to be modified while the licensed software remains unchanged.
Solution Approach 2:
The invention enables changing parameters and properties of process data through configuration settings rather than software modification. The configurable data processing section allows parameters such as data formats, transmission intervals, and processing rules to be adjusted without requiring software relicensing or reinstallation.
2Adaptability or versatility
If process data are changed on the rail vehicle, then the system becomes more adaptable to new requirements, but software relicensing and reinstallation are required which increases cost
Solution Approach 1:
The system divides the software architecture into licensed core functions and configurable data processing functions. The configurable data processing section can be modified independently without affecting the licensed software, eliminating relicensing costs for data changes.
Solution Approach 2:
The control unit is designed with universal configurability to handle multiple types of process data and transmission protocols. This multi-functionality is achieved through configuration rather than requiring different licensed software versions, reducing costs.
3Adaptability or versatility
If configurable data processing is implemented, then flexibility in process data transmission is improved, but device complexity increases
Solution Approach 1:
The invention introduces a diagnosis server as an intermediary between the control unit and the external system. The diagnosis server with its configurable data management section handles the complexity of configuration and data processing, while the control unit maintains relatively simple configurable connection interfaces.
Data Source
AI summary
An arrangement for transmitting process data between a rail vehicle and a track-side control entity. The rail vehicle has sensors, a controller, and a diagnostics server. Sensor measured values determined on the rail vehicle are transmitted to the controller as process data. The controller has a configurable data processing system to prepare process data of a selected sensor for transmission to the diagnostics server. The controller is connected to the diagnostics server via a configurable connection for the purpose of process data transmission. This connection has bus-linked transmission options, one of which can be selected depending on the configuration. The diagnostics server has a configurable data management section and a configurable data processing system. Read-in process data is processed on the basis of functions by these configurations. The process data processed in this way then reaches the trackside. The rail vehicle configurations can be adjusted from the trackside.
