Railway Control Interface Segmentation for Operator Focus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling railway systems are complex and cumbersome for operators, requiring manual effort to manage safety-relevant state changes, which can lead to errors and inefficiencies.
Innovation Solution
A control device that automatically displays a special image for safety-relevant state changes, allowing operators to perform predetermined actions more easily and safely, with fewer field elements shown, and featuring unique control elements not present in the overview image, ensuring focused attention and preventing incorrect operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the overview image displays all field elements, then the operator gets a complete overview of the railway system, but the operator's attention is分散 and the interface becomes complex
Solution Approach 1:
The interface is segmented into two distinct views: an overview image showing all field elements and a special image showing only relevant field elements for the current operation. This segmentation allows the operator to switch between comprehensive monitoring and focused operation modes, resolving the contradiction between having complete information and maintaining focus.
Solution Approach 2:
The system dynamically switches between the overview image and special image based on the operational context. When a safety-relevant state change is required, the system automatically transitions to the special image view, making the interface adaptive to the operator's needs and reducing cognitive load.
2Ease of operation
If the operator must manually call up the special image for predetermined operations, then the operator has control over when to focus on specific elements, but the operator effort and time required increase
Solution Approach 1:
The system performs preliminary action by automatically displaying the special image when a safety-relevant state change is required, eliminating the need for the operator to manually navigate to the correct view. This automation saves time and reduces operational steps while maintaining safety through the predetermined action requirement.
Solution Approach 2:
The control device serves itself by automatically managing the display transitions between overview and special images based on the operational state, reducing the burden on the operator and allowing them to focus on the critical safety-relevant actions rather than interface management.
3Ease of operation
If the special image shows fewer field elements, then the operator can focus better on the specific operation, but the operator loses context of the overall system
Solution Approach 1:
The system dynamically allows the operator to switch between the focused special image view and the comprehensive overview image view. This dynamic switching capability ensures that the operator can access detailed operational context when needed while maintaining awareness of the overall system state, resolving the information loss issue.
4Reliability
If control elements are only present in the special image, then safety is increased by preventing incorrect operations, but the interface becomes less consistent
Solution Approach 1:
The interface is segmented into different functional zones: the overview image for monitoring and the special image for execution of safety-relevant operations. Each zone has appropriately placed control elements for its purpose, with control elements for safety-critical actions only appearing in the special image where they are needed, improving safety without compromising overall interface consistency.

AI summary
In order to provide a method for controlling a railway installation (1) which has a plurality of field elements (4), in which current state information of the field elements (4) is displayed in an overview image (5) recognizably for an operator and in which a safety-relevant predetermined state change of at least one field element (4) is only carried out if a predetermined operating action has been carried out by the operator, it is proposed that when the safety-relevant predetermined state change is requested, at least one special image (6) assigned to the field element (4) is automatically displayed recognizably for the operator and the predetermined operating action is carried out by the operator with the help of the special image (6), wherein the special image (6) displays the state information of fewer field elements (4) than in the overview image (5).The invention also relates to a control device (2) for a railway technical system (1).
