Patent number: 11870659Abstract: Systems, methods, and apparatuses for industrial equipment diagnostics are disclosed. Specifically, a bus controller operatively connected to a processor is physically connected to two or more controller area network (CAN) buses, wherein each CAN bus operates according to a different protocol. The bus controller is configured to control the rate at which messages are received on certain buses by adjusting parameters such as a baud rate and sample rate. The bus controller is further configured to filter or mask certain CAN bus messages based on identifiers within the messages. The bus controller is operatively connected to a remote processing system for processing the CAN bus messages from their raw data format into a useable format. The remote processing system performs diagnostic analysis on the processed CAN bus messages, and furthermore performs predictive analytics on the processed CAN bus messages to identify patterns or discrete events indicative of future system failures.Type: GrantFiled: June 24, 2022Date of Patent: January 9, 2024Assignee: Norfolk Southern CorporationInventors: Ingrid Crafford, Nhut Doan, Dennis Quinn, Jeremy Laskos

Patent number: 11859350Abstract: Systems, devices, media, and methods are presented for controlling remote equipment in a network. A switch heater control system includes a weather modeling function. The system periodically obtains weather data according to a predetermined time interval. Based on the closest weather data set, the weather modeling function generates a hyperlocal forecast associated with each switch heater location. The system includes an active snowfall mode and a maintenance mode that controls heating based on an estimate of local snow depth, adjusted for wind conditions and passing trains. When the hyperlocal forecast indicates heating is required, the system calculates a melt duration, starts a timer, and transmits a start signal to the switch heater.Type: GrantFiled: March 10, 2023Date of Patent: January 2, 2024Assignee: Norfolk Southern CorporationInventors: Daniel W.

Patent number: 11507779Abstract: Systems, devices, media, and methods are presented for training a predictive model to detect objects in digital images, such as detecting whether a cotter key is present or absent in a digital photograph of a rail car coupler. The training system includes curating a plurality of training datasets, each including a number of raw images, together with a number of adjusted, augmented, and duplicate images. The predictive model includes a localization algorithm and an ensemble of models for classification. The localization algorithm is a deep convolutional neural network (CNN) which identifies a region of interest. One of more of the deep CNN classification models generates a plurality of candidate regions associated with each region of interest, thereby generating a large number of additional regions useful for training.

Patent number: 11384491Abstract: Systems, devices, and methods are presented for securing a railroad tie atop a support. In one implementation, a unitary length of metal rod is made into a clip that includes a vertical leg, a horizontal leg, and a resilient hook-shaped portion having a hook point. The hook-shaped portion is made so that the clip is biased toward a seated position, with the hook point positioned beneath part of the support. During installation, the vertical leg is placed through a hole in the railroad tie, driven downward until the resilient hook-shaped portion collapses into a compressed position, and driven further until the hook point moves beyond a free edge of the support and expands into the seated position. The clip secures the railroad tie without any additional parts and without requiring a worker to labor beneath the support.Type: GrantFiled: October 9, 2019Date of Patent: July 12, 2022Assignee: Norfolk Southern CorporationInventors: Dustin Lange, Robert Gannon

Patent number: 9171345Abstract: A system and method for determining rail terminal capacity needs. In one embodiment, terminal railcar inventory is determined periodically throughout a specific time interval based on terminal traffic data. Train traffic data is accessed and indexed into discrete time periods, such as daily and hourly intervals. Dwell occupancy indexes are created with periodic intervals, and assigned dwell occupancy values based on said dwell occupancy definitions and traffic data. The railcar inventory of the train terminal at any particular time may then be determined by cross-tabulating the occupancy dwell values, and applying business rules. The number and size of tracks needed to accommodate a rail terminal may be determined by assigning blocks of railcars to terminal tracks. Using the railcar inventory, a list of railcar blocks, railcar block sizes, railcar block classifications, and track classifications is created.Type: GrantFiled: February 15, 2013Date of Patent: October 27, 2015Assignee: Norfolk Southern CorporationInventor: Stefano Rieppi
