Definitions
- FIG. 1 shows a schematic of a locomotive 10, that may be either an AC or DC locomotive.
- the locomotive 10 is comprised of several relatively complex subsystems, each performing separate functions. By way of background some of the subsystems and their functions are listed below.
- An air and air brake subsystem 12 provides compressed air to the locomotive, which uses the compressed air to actuate the air brakes on the locomotive and cars behind it.
- a battery supplies power to a cranker subsystem 16 to start a diesel engine for operation of a DC bus and a HVAC system.
- the DC bus in turn provides voltage to maintain the battery at an optimum charge.
- An engine cooling subsystem 20 provides the means by which the engine and other components reject heat to the cooling water. In addition, it minimizes engine thermal cycling by maintaining an optimal engine temperature throughout the load range and prevents overheating in tunnels.
- An equipment ventilation subsystem 22 provides the means to cool the locomotive equipment.
- An event recorder subsystem records FRA required data and limited defined data for operator evaluation and accident investigation. For example, such recorder may store about 72 hours or more of data.
- a fuel monitoring subsystem provides means for monitoring the fuel level and relaying the information to the crew.
- a propulsion subsystem 24 provides the means to move the locomotive. It also includes the traction motors and dynamic braking capability. In particular, the propulsion subsystem 24 receives electric power from the traction alternator and through the traction motors, converts that power to locomotive movement.
- the propulsion subsystem may include speed sensors that measure wheel speed that may be used in combination with other signals for controlling wheel slip or creep either during motoring or braking modes of operation using control technique well-understood by those skilled in the art.
- a shared resources subsystem includes the I/O communication devices, which are shared by multiple subsystems.
- the collected expert data and or the identified target failure modes may be used by an identifier module 294 to identify one or more signals to be monitored for measuring performance of the respective subsystem.
- a processor 301 made up of a signal monitor module 302 receives the signal to be monitored, i.e., the PPG signal, and used for calculating the predicted fuel value (PFV) from Eq. 1.
- the adjusting factors may be empirically or experimentally derived by collecting actual data and/or simulation data that takes into account multiple scenarios of locomotive operation, and should preferably include a sufficiently large sample of locomotives and/or fuel delivery subsystems so as to statistically demonstrate the validity and accuracy of the correcting factors and/or transfer function of Eq. 1.
- a submodule 306 in module 304 allows for retrieving and/or generating the respective adjusting factors.
- a detection module 308 is electrically coupled to adjust module 304 to receive the adjusted fuel value, i.e., the value of the adjusted predicting signal. Detection module 308 includes a respective submodule 310 that allows for comparing the value of the adjusted fuel value against a nominal fuel value to determine the performance of the fuel delivery subsystem.
- a performance assessment module 314 may be readily used for generating and issuing a signal indicative of a degraded fuel delivery subsystem performance when the adjusted fuel value is beyond the first range of fuel values and within the second range of fuel values, that is, a cautionary signal that could be analogized to a yellow light in a traffic light.
- module 314 may be used for generating and issuing a signal indicative of unacceptable fuel delivery subsystem performance when the adjusted fuel value is beyond an upper limit of the second range of fuel values, that is, a warning signal that could be analogized to a red light in a traffic light that requires immediate action by the user, for example, the person evaluating a respective subsystem performance at a remote diagnostic service center or anyone and/or anything else that initiates diagnostic recommendations or actions.
