- the signals may be correlated to a status of the associated component. For example, when the value of a particular signal exceeds or falls below a corresponding threshold value, the associated components may be determined to be malfunctioning.
- the signals generated by sensors 38 may be directed to controller 46 for further processing.
- Locating device 40 may be configured to generate signals indicative of a geographical position and/or orientation of train 10 relative to a local reference point, a coordinate system associated with a region, a coordinate system associated with Earth, or any other type of 2-D or 3-D coordinate system.

Locating device 40 may receive and analyze high-frequency, low-power radio or laser signals from multiple locations to triangulate a relative 3-D geographical position and orientation. Signals generated by locating device 40 may be directed to controller 46 for further processing.
- Communicating device 42 may be configured to facilitate data communication between different components (e.g., between sensors 38 and controller 46, between controller 46 and display 44, and/or between controller 46 and another controller offboard train 10 at a back office) of system 36.

- Communicating device 42 may include hardware and/or software that enable the sending and/or receiving of data messages through a communications link.
- the communications link may include satellite, cellular, infrared, radio, and any other type of wireless communications.
- the communications link may include electrical, optical, or any other type of wired communications, if desired.
- display 44 and/or controller 46 may be located offboard train 10 (e.g., at the back office), and may communicate directly with the other onboard components of system 36 via communicating device 42, if desired. Other means of communication may also be possible.
- Display 44 may include one or more monitors (e.g., a liquid crystal display (LCD), a cathode ray tube (CRT), a personal digital assistant (PDA), a plasma display, a touch-screen, a portable hand-held device, or any such display device known in the art) configured to actively and responsively show trip simulation results to the user of system 36.
- Display 44 is typically disposed in close proximity to the cabin of train 10 and within the view of the operator of train 10. However, as described above, display 44 could be located offboard train 10, in one embodiment.
- Display 44 may be connected to controller 46, and controller 46 may execute instructions to render graphics and images on display 44 that are associated with a simulated trip.
- Controller 46 may embody a single microprocessor or multiple microprocessors that include a means for controlling an operation of system 36 based on information obtained from any number of train components via sensors 38, from locating device 40, and/or from communications received via communicating device 42. Numerous commercially available microprocessors can be configured to perform the functions of controller 46. Controller 46 can include a memory, a secondary storage device, a processor, and any other components for running an application. Various other circuits may be associated with controller 46 such as power supply circuitry, signal conditioning circuitry, solenoid driver circuitry, and other types of circuitry.
- controller 46 may be configured to perform simulations of trips to be completed by train 10. More specifically, controller 46 may be configured to perform simulations of a remainder of a trip assigned to train 10, following malfunction of a component of train 10 during the trip. The simulations may be performed based on a known profile of track 22 (e.g., horizontal track changes, vertical track changes, track quality and/or friction, speed limits, road crossings, and other trip-related data) yet to be traversed by train 10, based on known train information (e.g., length, weight, pulling capacity, available power, a fuel consumption, a thermal characteristic, a cargo type and value, a delay cost, a locomotive configuration and performances, a braking capacity, a rolling resistance, and other train-related data.),
- train information e.g., length, weight, pulling capacity, available power, a fuel consumption, a thermal characteristic, a cargo type and value, a delay cost, a locomotive configuration and performances, a braking capacity, a rolling resistance, and other train-related data.
- the simulations may be performed using maps, equations, graphs, tables, scales, and other preprogrammed algorithms stored in the memory or otherwise communicated to controller 46.
- the results of the simulation may include static results and dynamic results.
- the static results may consist of either a positive response or a negative response regarding the desired goals. For example, if the desired goal is to reach a destination, the static results of the simulation performed by controller 46 may simply indicate that train 10 will or will not reach the destination. Similarly, if the desired goal is a time of arrival, the static results of the simulation may simply indicate that train 10 will or will not reach the destination on time.
- Dynamic results may consist of an anticipated performance value associated with a particular operation of train 10, indexed to any given time, location, or distance along the remainder of the trip. For example, the dynamic result could include an anticipated location, speed, fuel consumption, temperature, pressure, etc., for given intervals of time, location, or distance.
- the results of the simulation may be used by the back office, by controller 46, and/or by the onboard operator of train 10 in making decisions regarding the given malfunction. For example, based on the simulation results, a decision may be made to shut down train 10 at its current location, to continue to a better location for repairs before shutdown, to complete the assigned trip, to dispatch a repair vehicle, to modify train operation and continue, to dispatch replacement equipment (e.g., replacement locomotive 12) etc.
- a decision may be made to shut down train 10 at its current location, to continue to a better location for repairs before shutdown, to complete the assigned trip, to dispatch a repair vehicle, to modify train operation and continue, to dispatch replacement equipment (e.g., replacement locomotive 12) etc.
- controller 46 in addition to performing trip simulations following a component malfunction, controller 46 can also be configured to automatically affect operation of train 10 based on results of the simulated trip and/or in response to commands received from the operator of train 10 or from the back office. For example, controller 46 may be configured to command adjustments be made to the different components of train 10. These adjustments may include, among other things, a throttle setting of engine 26, isolation of the malfunctioning component (e.g., of a particular traction motor 25), overriding of an existing operational limit (e.g., of a temperature, pressure, or speed limit) associated with the malfunctioning component, changing a blend ratio of different fuels, etc. In some situations, controller 46 may first simulate operation of train 10 using an anticipated adjustment, before actually implementing the adjustment. In this way, confidence in the adjustment may be increased.
- a throttle setting of engine 26 isolation of the malfunctioning component (e.g., of a particular traction motor 25), overriding of an existing operational limit (e.g., of a temperature, pressure, or speed limit) associated with the malfunction
- Fig. 2 illustrates an exemplary Graphics User Interface (GUI) 48 that may be shown on display 44 by controller 46 during and/or following simulation of a trip assigned to be undertaken by train 10.
- GUI 48 may include several areas where information can be input, commands may be generated, and simulation results can be displayed.
- a first area 50 of GUI 48 may illustrate a map showing the current location of train 10 relative to a known track profile of the assigned trip.
- Area 50 may illustrate geographical features surrounding track 22 (e.g., mountains, streams, road crossings, etc.), a horizontal and/or vertical shape of track 22, and an orientation and length of train 10 at the known location.
- the location of train 10 may be received by controller 46 from locating device 40, and the track profile may be manually entered and/or automatically downloaded after assignment of the particular trip.
- a second area 52 of GUI 48 may provide a summary associated with train 10 and/or the assigned trip.
- area 52 may show an identification of train 10, an identification of locomotives 12 in train 10, a number of cars (a.k.a., wagons) connected to locomotives 12, a weight of train 10, a length of train 10, a type of payload carried by train 10, a travel direction, a payload source, a destination, a scheduled time of arrival (STA), an expected time of arrival (ETA), an earliest possible time of arrival, and a crew
- This information may be manually entered into system 36 prior to a start of the assigned trip, and/or automatically looked up and/or collected from any number of different sources and databases, as desired.
- a third area 54 of GUI 48 may be an alert area.
- controller 46 may generate an error flag corresponding to the deviation.
- controller 46 may provide a visual alert within area 54, making the user of system 36 aware of a corresponding component malfunction.
- the depicted alert indicates that a locomotive 12 identified as #1 is experiencing low-fuel pressure, and has been shut down.
- a fourth area 56 may provide an illustration of the offending component and/or part of train 10 that is experiencing the malfunction.
- a fifth area 58 of GUI 48 may be configured to illustrate the static results of a trip simulation run by controller 46.
- the static results may include the simple positive/negative answer regarding train 10 being able to achieve the desired goal, given the current malfunction.
- the static results may also show some calculated values corresponding to the anticipated performance of train 10. These values may include, for example, a maximum amount of tractive force that can be applied by the remaining locomotives 12 after locomotive #1 is shut down, a maximum wheel adhesion, an amount of fuel anticipated to be consumed, and a time required to complete the assigned trip given the derated performance of train 10.
- Controller 46 may determine the simple answer displayed in area 58 by comparing the performance goal with the simulated results. For example, if the goal is only for train 10 to reach a particular destination, controller 46 may simply compare an amount of tractive effort required to pull train 10 over the known track profile ahead of train 10 with an amount of tractive effort still available after locomotive #1 is shut down (or otherwise given the current malfunction or failure). Additional comparisons, for example regarding an amount of required fuel relative to available fuel or thermal characteristics of engines 26 and/or traction motors 25 relative to known limits, may also or alternatively be made. Other goals can include a time to reach the destination, a fuel consumption amount, or something else. The performance goal may be input to system 36 by way of GUI 48.
- a final area 60 of GUI 48 may be configured to illustrate the dynamic results of a trip simulation run by controller 46.
- the dynamic results shown in area 60 may include results of the simulation indexed to time, distance, and/or location.
- area 60 of Fig. 2 shows a speed of train 10 at incremental locations along the remainder of the trip.
- GUI 48 may include only area 58, only area 60, or both areas 58 and 60. It is further contemplated that the user of GUI 48 may select which of these areas to show.
- controller 46 may be configured to first simulate operation of train 10 using an anticipated adjustment, before actually implementing the adjustment. Specifically, when the static result of an initial simulation is negative or only marginally acceptable, controller 46 and/or the user of GUI 48 may cause the static simulation to be rerun under different conditions or cause a more accurate dynamic simulation to be run. That is, virtual adjustments may be made to the different components of train 10 in the corresponding simulation model, and controller 46 may rerun the simulation to see what effect the virtual adjustments could have on the results.
- controller 46 could rerun the simulation after virtually isolating (e.g., turning off) the problematic traction motor 25.
- the known thermal limit may be ignored or the malfunction otherwise overridden, and controller 46 may rerun the simulation to determine the results (e.g., the collateral damage and associated operational cost) of doing so.
- the collateral damage caused by ignoring a pre-set limit or overriding the malfunction may be less than the cost of not reaching a destination or of arriving late.
- exemplary adjustments could include adjusting a throttle setting on an engine experiencing a malfunction, reassigning a lead locomotive as a trail locomotive and vice-versa, resetting a component, etc. Based on the results of the rerun simulation, adjustments could be commanded by the operator via GUI 48 or automatically implemented by controller 46.
- Fig. 3 illustrates a flowchart depicting an exemplary simulation operation performed by controller 46. Fig. 3 will be discussed in more detail below to further illustrate the disclosed concepts.
- the disclosed system can be applicable to any train that includes components, which could malfunction during completion of a trip.
- the disclosed system may provide a way to determine if the train is able to successfully complete the trip, given the malfunction.
- the disclosed system may simulate a remainder of the trip while accounting for the effects of the malfunction. This simulation may aid in making decisions regarding the status of the train and the malfunctioning component. Operation of system 36 will now be explained in detail, with respect to Fig. 3.
- the process of Fig. 3 may begin with controller 46 monitoring operational conditions of the different components of train 10 (Step 300). As described above, the condition of these components may be monitored by way of sensors 38. Specifically values of the signals generated by sensors 38 may be continuously compared to operational thresholds and/or ranges. Based on the comparison of these values, controller 46 may determine if an abnormal (e.g., malfunction) condition has been detected (Step 310), and then determine if the abnormal condition could affect success in train 10 achieving the desired goal (e.g., reaching its destination within a desired window of time) (Step 320).
- an abnormal condition e.g., malfunction
- controller 46 may make the determination of step 320 based on the type and/or identification of the component determined to be malfunctioning, based on the results of the values comparison, and based on one or more maps, equations, tables, and/or algorithms stored in memory.
- controller 46 may log a fault and allow train 10 to complete the trip without intervention (Step 330). However, when controller 46 determines at step 320 that the detected malfunction of the offending component could have a significant impact on completion of the trip, controller 46 may be automatically triggered to simulate the remainder of the trip, taking into account the detected abnormal condition and based on preloaded track profile and train information (Step 340). The results may thereafter be shown on display 44.
- controller 46 may be triggered to run trip simulations based on the malfunction detection or based on the shutdown of train 10, as desired. Accordingly, controller 46 may run the simulations while train 10 is stationary, in some instances, and while train 10 is underway, in other instances.
- additional simulations may be run to see if adjustments to the components of train 10 may improve the likelihood of train 10 successfully completing its assigned trip.
- the additional simulations may be triggered manually or automatically, as desired. In the example of Fig. 3, the simulations are triggered automatically.
- controller 46 may determine if the results of the initial simulation were successful (Step 350). When the results of the simulation indicate the assigned trip can be completed successfully (e.g., that the desired goals can be achieved), control may move to step 330. However, if the results of the initial simulation indicate the assigned trip cannot be completed successfully, control may instead move to step 360.
- controller 46 may determine if adjustments can be made to the malfunctioning component of train 10 to positively affect the results of the simulation. For example, if the initial simulation shows that completely shutting down locomotive # 1 (from the above GUI 48 example), makes it impossible for train 10 to complete its assigned trip within the desired window of time, controller 46 may try to determine if the engine of locomotive # 1 could instead be run at 1 ⁇ 2 throttle (e.g., at notch setting 3 or 4) to complete the trip in a timely manner without causing excessive collateral damage (e.g., without destroying engine 26). If adjustment options are available, controller 46 may be configured to implement corresponding virtual adjustments to the simulation model (Step 370), and then return to step 340.
- step 350 when control moves from step 350 to step 330, the virtual adjustments used during the subsequent simulations may become real and implemented in step 330. If controller 46 determines that no adjustment options exist that are likely to improve the results of the simulation, control may instead move from step 360 to step 380, wherein a separate trip failure protocol is implemented.
