Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway control systems face challenges in achieving compatibility between control centers and sub-centers from different manufacturers, making system expansion and cross-operation difficult due to disparate data formats and interfaces.
Innovation Solution
The implementation of a cloud computing connection secured by security gateways between control centers and sub-centers, using standardized graphics protocols for transmitting and displaying operating status images as graphic packages, allowing for a unified standard operating interface and centralized configuration, with minimal software requirements in control centers and flexible software upgrades in sub-centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control centers and sub-centers from different manufacturers are integrated, then system versatility and adaptability improve, but system complexity and integration difficulty increase due to incompatible data formats and interfaces
Solution Approach 1:
The patent introduces a standardized graphic package transmission interface as an intermediary layer between control centers and sub-centers. This interface uses universal graphic protocols (SVG, X11, VNC) to transmit operating status images, decoupling the specific data formats of different manufacturers' systems. The graphic package serves as a mediator that enables compatibility without requiring deep integration between heterogeneous systems.
Solution Approach 2:
The system separates the display function from the control function by dividing the interface into independent graphic package components. Operating status images are segmented into standardized graphic elements that can be transmitted independently through cloud computing connections. This segmentation allows different manufacturers' systems to interact through universal graphic protocols without requiring full system integration.
2Reliability
If proprietary software and configuration are maintained in each sub-center, then manufacturer-specific functionality is preserved, but system expansion and cross-operation become difficult
Solution Approach 1:
The patent implements a universal graphic package interface that can handle multiple manufacturers' proprietary formats through a single standardized transmission protocol. The control center's display device can universally display graphic packages from any sub-center regardless of the manufacturer, while sub-centers maintain their proprietary software for generating the graphic packages. This universality enables both preservation of manufacturer-specific functionality and system expandability.
3Ease of manufacture
If centralized configuration data storage is implemented, then software maintenance and upgrades are simplified, but system security requirements increase
Solution Approach 1:
The patent extracts configuration data and operating status information from the control center and stores it centrally in the sub-centers. This extraction reduces the software maintenance burden on control centers while maintaining security through distributed storage. The graphic package transmission interface enables the control center to access and display configuration data without storing it centrally, thus maintaining security while simplifying maintenance.

AI summary
The invention relates to a railway control system having at least one control centre (1) which is connected to at least one subsidiary control centre (2), wherein the control centre (1) is designed to monitor operating state images which are produced in an imaging device (5) of the subsidiary control centre (2). In order to make it easier to bring about compatibility between the control centres (1) and subsidiary control centres (2) of a wide variety of designs, there is provision that the imaging device (5) is designed to produce and transmit the operating state images in the form of graphic packets and that the control centre (1) has a display device (7) for displaying the operating state images on the basis of a standardized graphic protocol.
