Abstract

Official abstract text for this publication.

A system and method for automating railroad maintenance by a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables collision avoidance between members of the tie gang performing maintenance on railway assets (e.g., Rails, Ties, Ballasts, Turnouts, Crossings, etc.). The system can generate production numbers for the railway assets and evaluate an asset queue for the tie gang to perform maintenance. The system can utilize real-time updates from the tie gang to optimize work output. The system can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset. The system also provides for a heads-up-display (HUD) to notify an operator of relevant information, such as maintenance information, travel indicators, and updated asset queue. The system can identify a next location and calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics.

First claim

Opening claim text (preview).

What is claimed is: 1 . A system for master production scheduling using machine generated production numbers, comprising: a memory for storing a queue of railway assets to receive maintenance based on maintenance information for the railway assets and a geographic region; a processor configured to generate work production numbers for the queue of railway assets and manage a production output for a tie gang proximate to the geographic region by performing the steps of: identifying the railway assets to maintain in the geographic region; generating the queue of railway assets to maintain within the geographic region; identifying the tie gang proximate to the geographic region based on a work schedule of the tie gang or a location determination of the tie gang; generating production numbers for each railway asset in the queue of railway assets, wherein the production numbers for a railway asset are unique for the railway asset, and wherein the production numbers are one of: randomly generated, pseudo-randomly generated, and sequentially generated; updating inventory with the unique production numbers associated with each of the railway assets; correlating the production numbers of the railway assets with the geographic region via a geographic identifier; scheduling the tie gang to perform maintenance on the railway assets by transmitting the production numbers to the tie gang; receiving updates from the tie gang as the tie gang performs the maintenance on the railway assets; and updating the queue of railway assets in real-time to organize remaining railway assets to receive maintenance; and a cloud environment for organizing workflow production and updating the queue of railway assets to receive maintenance in real-time. 2 . The system of claim 1 , wherein the processor is further configured to perform the steps of determining whether the railway asset already exists in the queue of railway assets. 3 . The system of claim 1 , wherein the processor is further configured to perform the steps of comparing an efficiency of the tie gang with the queue of railway assets in the geographic region to estimate a completion time for performing maintenance on the railway assets. 4 . The system of claim 1 , wherein identifying the railway assets to maintain is based on an inventory. 5 . The system of claim 1 , wherein identifying the location of the tie gang is based on a received signal. 6 . The system of claim 5 , wherein the signal is received from the tie gang. 7 . The system of claim 6 , wherein the signal includes location information for the tie gang. 8 . The system of claim 1 , wherein the processor is further configured to perform the steps of estimating a completion time for performing maintenance on the railway assets. 9 . The system of claim 1 , wherein the processor is further configured to perform the steps of identifying the efficiency of the tie gang in terms of a railway asset completion rate. 10 . The system of claim 9 , wherein the production numbers in the queue are based on the efficiency of the tie gang. 11 . A method of master production scheduling using machine generated production numbers, comprising: identifying, via a processor, one or more railway assets to maintain in a geographic region; generating a queue, stored in a memory, of railway assets to maintain within the geographic region; identifying the tie gang proximate to the geographic region based on a work schedule of the tie gang or a location determination of the tie gang; generating production numbers for each railway asset in the queue of railway assets, wherein the production numbers for a railway asset are unique for the railway asset, and wherein the production numbers are one of: randomly generated, pseudo-randomly generated, and sequentially generated; updating inventory with the unique production numbers associated with each of the railway assets; correlating the production numbers of the railway assets with the geographic region via a geographic identifier; scheduling the tie gang to perform maintenance on the railway assets by transmitting the production numbers to the tie gang; receiving updates from the tie gang as the tie gang performs the maintenance on the railway assets; updating the queue of railway assets in real-time to organize remaining railway assets to receive maintenance; and organizing workflow production and updating the queue of railway assets to receive maintenance in real-time, via a cloud environment. 12 . The method of claim 11 , further comprising determining whether the railway asset already exists in the queue of railway assets. 13 . The method of claim 11 , further comprising comparing an efficiency of the tie gang with the queue of railway assets in the geographic region to estimate a completion time for performing maintenance on the railway assets. 14 . The method of claim 11 , wherein identifying the railway assets to maintain is based on an inventory. 15 . The method of claim 11 , wherein identifying the location of the tie gang is based on a received signal. 16 . The method of claim 15 , wherein the signal is received from the tie gang. 17 . The method of claim 16 , wherein the signal includes location information for the tie gang. 18 . The method of claim 11 , further comprising estimating a completion time for performing maintenance on the railway assets. 19 . The method of claim 11 , further comprising identifying the efficiency of the tie gang in terms of a railway asset completion rate. 20 . The method of claim 19 , wherein the production numbers in the queue are based on the efficiency of the tie gang.
