Railroad Interlocking Remote Control Panel Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Custom Local Control Panels (CLCPs) in railway management systems are inflexible, preventing easy expansion of monitoring and user input control throughout railway facilities, limiting the ability of operators and maintenance personnel to access and manage railway operations effectively.
Innovation Solution
A system that provides primary and remote control panels capable of duplicating the functionality of the primary panel, allowing for expanded monitoring and control of railway interlocking systems without modifying the existing interlocking system, using a dedicated or shared network, where the primary panel communicates with the interlocking system and remote panels display and manage status messages and user inputs, enabling transparent and cost-effective expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom local control panels are designed with site-specific track layouts and hardwired connections, then the system provides localized control capability, but the system becomes inflexible and difficult to expand to additional locations
Solution Approach 1:
The patent implements remote control panels that are identical copies of the primary panel, allowing multiple locations to have the same functionality without customizing each location. The remote panels replicate the primary panel's display and control capabilities, enabling easy expansion throughout the facility while maintaining consistency and reducing configuration complexity.
Solution Approach 2:
The primary control panel is designed to serve multiple functions: it acts as both a standalone control interface and a central communication hub that manages multiple remote panels. This universal design allows the same hardware to function differently based on its role in the network, reducing the need for location-specific customizations.
2Ease of operation
If multiple custom control panels are deployed throughout the facility, then localized access and control are improved, but the cost and complexity of customization increase
Solution Approach 1:
Instead of customizing each control panel for specific locations, the patent uses identical remote panel copies distributed throughout the facility. Each remote panel provides localized access with the same functionality as the primary panel, eliminating customization costs while maintaining ease of operation at multiple locations.
Solution Approach 2:
The remote panels are designed to be self-configuring through software installation rather than requiring physical customization. The panels automatically integrate into the network and receive their configuration through communication with the primary panel, reducing manufacturing and installation costs.
3Adaptability or versatility
If remote control panels are added to expand monitoring coverage, then operator accessibility is improved, but the interlocking system complexity increases
Solution Approach 1:
The primary control panel serves as an intermediary between the interlocking system and multiple remote panels. It receives status messages from the interlocking system and distributes them to remote panels, while also collecting control requests from remote panels and forwarding them to the interlocking system. This mediator architecture allows monitoring coverage to expand without increasing the complexity of the core interlocking system.
Solution Approach 2:
Remote panels are implemented as software-based copies rather than hardware modifications to the interlocking system. This allows multiple instances to be deployed without changing the interlocking system's internal complexity, as each remote panel is an independent copy that communicates through the primary panel interface.

AI summary
A system and method provides for expanded monitoring and control of a railroad wayside interlocking system that monitors a plurality of track side and train systems and controls a plurality of train and track control devices with a primary control panel system communicating with the interlocking system over a first communication interface and with a remote control panel over a second communication interface, receiving interlocking status messages for visually displaying a current status state of the monitored systems, replicating the received interlocking status messages, determining a current status state for the control devices, communicating replicated interlocking status messages or the determined current status state over the second communication interface to one or more remote control panel systems, and receiving requests from the one or more remote control panel systems, which are then transmitted to the wayside interlocking system by the primary control panel system.
