Automated Distributed Power Linking for Locomotive Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing distributed power operations in trains require manual intervention, which is time-consuming and labor-intensive, especially for long trains or those with multiple remote locomotives, and lacks efficiency in handling lead locomotive changes or faults.
Innovation Solution
A system and method for remotely establishing and managing distributed power operations using a communication network with a distributed power setup unit, allowing for automated linking and de-linking of propulsion units through identity-based signals, enabling a single operator to control multiple locomotives from a central location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual setup and linking of locomotives is performed at the rail yard, then distributed power operations can be established, but significant time and manpower are consumed
Solution Approach 1:
The patent replaces manual mechanical operations (operators physically entering locomotives to enter data and initiate linking) with an automated communication-based system. The setup unit transmits setup data and linking signals automatically through a communication network, eliminating the need for operators to manually access each locomotive and significantly reducing setup time while maintaining reliable distributed power operation establishment.
2Reliability
If manual entry of locomotive data and linking is performed, then distributed power operations can be established, but labor intensity increases
Solution Approach 1:
The system enables self-service operation where the automated setup unit independently performs data entry and linking operations without requiring operator intervention. The unit automatically transmits setup data to remote locomotives and manages linking based on pre-configured parameters, eliminating manual labor while ensuring reliable establishment of distributed power operations.
3Adaptability or versatility
If lead locomotive replacement is performed manually, then control can be transferred to a new lead locomotive, but the process consumes significant time for long trains
Solution Approach 1:
The system performs preliminary action by pre-configuring the setup unit with replacement lead locomotive data before the actual replacement occurs. When a lead locomotive needs replacement, the setup unit automatically transmits the new lead locomotive's data to all remote locomotives and manages the linking process, enabling rapid control transfer without manual intervention and significantly reducing replacement time for long trains.
4Productivity
If automated remote setup is implemented, then manpower requirements are reduced, but system complexity increases
Solution Approach 1:
The setup unit serves multiple functions: it stores setup data for multiple locomotives, transmits setup data automatically, manages linking and de-linking operations, and handles lead locomotive replacements. This multi-functionality consolidates what would otherwise require multiple separate systems or manual operations into a single automated unit, reducing manpower requirements while managing system complexity through integration.

AI summary
A method for controllably linking propulsion units in a vehicle consist includes transmitting a linking signal having an identity of a lead propulsion unit. A remote propulsion unit is remotely controlled by the lead unit when the identity matches a designated identity stored onboard the remote unit. A de-linking signal is transmitted from the lead unit when the lead unit is to be decoupled from the vehicle consist. The de-linking signal includes a replacement identity of a replacement propulsion unit. A replacement linking signal is transmitted from a second lead unit. The remote propulsion unit allows the second lead propulsion unit to remotely control the operations of the remote propulsion unit when replacement identity stored onboard the remote propulsion unit matches an identity that is communicated in the replacement linking signal.
