Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for updating and configuring wayside devices in railroad systems are inefficient and time-consuming, requiring manual intervention by technicians to ensure safety, which is costly and labor-intensive due to the need for physical presence at each device along thousands of miles of tracks.
Innovation Solution
A system and method that utilize a movement planner to establish a communication link with wayside devices, assess safety parameters such as vehicle location and device status, and remotely update or configure the devices when it is safe to do so, eliminating the need for physical presence by technicians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual updating and configuring of wayside devices is performed by technicians, then safety can be ensured by direct inspection, but the process becomes inefficient and time-consuming
Solution Approach 1:
The wayside device performs self-updating and self-configuring through automated software updates transmitted via communication systems. The device autonomously receives, validates, and installs updates without requiring manual intervention, thereby ensuring safety through programmed protocols while dramatically improving efficiency by eliminating technician travel and manual operations across thousands of miles of track.
Solution Approach 2:
The patent replaces the mechanical system of manual updates (technicians physically traveling to devices, manually inspecting tracks, and hand-uploading software) with an electronic/communication-based system. Software updates are transmitted digitally through communication links between central offices and wayside devices, substituting physical presence with electronic data transmission, thus maintaining safety through automated checks while achieving high efficiency.
2Ease of operation
If technicians physically travel to wayside devices for updates, then direct control and verification is possible, but substantial manpower and time are required
Solution Approach 1:
The patent introduces a communication system as an intermediary between the central office and wayside devices. This intermediary enables direct control and verification of update operations without requiring physical presence. The communication link transmits software updates, configuration data, and status information, allowing central operators to control remote devices directly while eliminating the time loss associated with technician travel.
Solution Approach 2:
The communication system serves multiple functions: transmitting software updates, verifying device status, confirming safety parameters, and enabling bidirectional communication between central offices and wayside devices. This multi-functional approach consolidates what would otherwise require multiple separate manual operations into a single integrated automated process, maintaining direct control capabilities while dramatically reducing time requirements.
3Productivity
If remote updating is implemented, then efficiency and cost-effectiveness improve, but safety verification becomes more complex
Solution Approach 1:
The patent implements preliminary safety verification through automated checks performed before software updates are applied. The system checks multiple parameters including track occupancy, device operational state, and update integrity prior to initiating the update process. This preliminary action ensures safety is verified through programmed protocols rather than manual inspection, maintaining high efficiency while managing verification complexity through systematic automated checks.
Solution Approach 2:
The system employs feedback mechanisms where the wayside device continuously reports its status, location, and operational parameters back to the central office. During the update process, real-time feedback confirms whether safety conditions are met, whether the update is proceeding correctly, and whether the device is ready to resume operation. This feedback loop manages verification complexity by providing automated, continuous monitoring rather than requiring complex manual verification procedures.
