- FIGs. 10-12 illustrate pages from a web site containing information related to the management of a fleet of locomotives.
- Such information may include design information, real time operating data, historical performance data including failure probabilities, parts inventories, and geographic information related to the assets, cargo being transported with the assets, parts, personnel and repair facilities, etc.
- Key to achieving efficient operation is the ability to communicate such information to people and places where it is needed, and to present the information in a format that makes it useful to accomplish the desired result. Accordingly, the inventors have envisioned the system 10 of Figure 1 for use in managing a fleet of mobile assets.
- the communication system 10 allows a variety of different types of users to obtain detailed and timely information regarding each of the mobile assets 12.
- Such users may include the transportation company 14 who owns and operates the locomotives 12, a customer 24 of the transportation company, personnel in a locomotive service center 22, personnel in a data center 18, and the engineer on-board each individual locomotive 12.
- the locomotives 12 may be equipped with a plurality of sensors for monitoring a plurality of operating parameters representative of the condition of the locomotive 12 and of the efficiency of its operation.
- the locomotive 12 may also be equipped with a GPS receiver 16 or other satellite based or local instrument for determining the geographic location of the locomotive 12. Data regarding the location of the locomotive 12 and its operating parameters may be transferred periodically or in real time to a data base 18 by a data link 20, such as a satellite system, cell phone, optical or infrared system, hard-wired phone line, etc.
- a data link 20 such as a satellite system, cell phone, optical or infrared system, hard-wired phone line, etc.
- MDSC Monitoring and Diagnostics Service Center
- affiliated with such a data center 18 may be one or more service centers 22 where the locomotives 12 are taken for repair and maintenance services.
- the data center 18 and service center 22 may both be linked to a global information network, such as the Internet 15, by known types of data connections.
- a global information network such as the Internet 15, by known types of data connections.
- Such links may typically be a computer interface through an internet service provider.
- the Internet and World Wide Web provide a means for communicating between the data center 18 and service center 22.
- these facilities may also be in communication with the transportation company user 14 via an Internet connection.
- Customers 24 of the transportation company or other members of the public may further be in communication with these facilities through Internet links. Because the Internet 15 and known web page formats provide a means for communicating data and information in a multi-media format, such a global information network is a useful communication tool for displaying and communicating the large amount of data that may be associated with the operation of a fleet of mobile assets 12.
- FIG 2 illustrates a method 28 for managing a fleet of mobile assets that may be implemented by using a communications system 10 as illustrated in Figure 1.
- Each mobile asset may be uniquely identified, such as by an identification number, as in step number 30 of Figure 2.
- One or more identifiers may also be associated with the cargo being transported with the mobile assets 12.
- the, operating parameters of each of the locomotives 12 may be monitored 32 by the on-board sensors. Preferably, such operating parameters are monitored in real time, and data related to these operating parameters is available for communication to a data center 18 wherever appropriate.
- the location of each asset is also determined 34, such as by using a GPS system or by otherwise identifying the locomotive to a particular location on the rail line.
- Data regarding both the location and the operating parameters for each locomotive 12 may be periodically downloaded 36 from an on-board data file to a centralized data base 39. In the event that a critical fault is identified 38 in one of the systems of a locomotive, it may be preferred to download data from the locomotive immediately
- the timing of the download may also be determined based upon the availability and quality of the data link 20 between the locomotive 12 and the data center 18.
- the database 39 located at the data center 18 may also include data representing inspection reports 42, maintenance records 44, and design information 46 related to the specific vehicles included in the plurality of mobile assets. For example, if a locomotive engine 12 is returned to a service center 22 for a periodic inspection and maintenance visit, information regarding the results of the inspection and maintenance activities may be used to update the database 39 for that particular locomotive 12.
- the database may also be updated 39 if the designer of the locomotive 12 provides any revised design parameters 46, such as a new part number for an upgraded component.
- the quantity of data in such a data base may be immense when considering the number of vehicles in some fleets, and when considering the amount of data that may be collected on a periodic basis regarding the performance of each of the vehicles.
- An Internet web page may be updated 56 to reflect the performance reports 50, operating statistics 52, and/or current location map 54 for the fleet of mobile assets.
- One or more such web pages may be utilized with appropriate hyperlinks to additional web pages.
- the level of detail presented to the user 14 may be controlled by that user.
- a location map 190 of FIG. 8 illustrating the current geographic location of each of the locomotives 12 owned by a transportation company may include a hyperlink 192 at the indication of the location of each of the locomotives 12.
- Such a map may also illustrate the location of service facilities.
- a road map may be generated showing the location of each truck along with its route.
- a hyperlink 192 may be provided on the map for each mobile asset to connect the user to an interconnected nested web page containing additional information regarding that particular vehicle.
- the location of the mobile asset may be seen on map 190, by double clicking a cursor on the symbol for a single locomotive 12, the speed, destination, route, cargo information, fuel level, crew information, and other operating information for that locomotive may be viewed on nested web pages.
- One user such as a customer 24 of the transportation company, may only be interested in the location of the train.
- Another user 14, such as a service engineer employed by the railroad may be interested not only in the location of the locomotive but also in the amount of fuel on board or other operating parameter. Both such users 14,24 can quickly obtain the information they need by a simple point and click operation using known Internet browser technology.
- Known search engine software technology may be provided 70 to allow a user to identify desired information related to the mobile assets 12 via the global information network 15. Access to an appropriate web page containing the desired information may then be provided via hyperlink directly from the search engine.
- An Internet web page display used with the present invention may incorporate the full power of the multi -media capabilities of a global information network 15.
- the location map 54 may include the use of color to indicate a readiness status for each locomotive, for example, green for a properly functioning locomotive, yellow for a locomotive exhibiting an anomaly in one of its operating parameters, and red for a locomotive having a critical fault.
- the user 14 of such information would be able to quickly assimilate a large volume of data and to have his/her attention directed to important portions of the data.
- Such a web page may also include links to additional pages containing drawings of component parts, specifications, or operating and repair manuals or other design parameters 46.
- Such video information may be accompanied by live audio information, including speech from the operator, thereby allowing the user 14, the operator located on the locomotive 12, and personnel at a service center 22 to conference regarding a developing anomaly.
- Communication over the global information network 15 using Internet Protocol allows packets of data to be communicated between different kinds of networks.
- the packets may consist of voice, text, video, audio or other types of data.
- the system 10 of Figure 1 is adaptable to make use of future platforms as they become available.
- a service recommendation may be developed 60.
- Information regarding the anomaly 58, critical fault 38, and/or service recommendation 60 may also be uploaded 56 to an Internet web page.
- a user may be notified 62 that new or urgent information has been displayed on the Internet web page.
- the user may be notified 62 by an electronic mail message, telephone call, fax or other simple form of communication.
- the user may then actively interact 68 with the web pages that present data regarding the mobile asset of interest. Such interaction may include a request by the user for additional information. Such a request would be transmitted to the locomotive operator or other appropriate person via the global information network connection, and the response would be communicated in return.
- the information available to the user on the Internet web page may also include information regarding services that are available 64 and/or a parts inventory 66 that may be important to any decision regarding a maintenance recommendation 60.
- Personnel located at a service center 22 may not only provide data for the user 14, but may also receive a communication from the user 14 regarding a planned maintenance activity, thereby facilitating the scheduling of maintenance activities at the service center 22.
- the operator of the locomotives who may be physically sitting in the front locomotive may not be aware that a degraded condition has developed in the third locomotive.
- a degraded cooling system may cause the third locomotive to throttle back to a reduced power output.
- the first and second locomotives are able to provide the necessary power, the progress of the train is unimpeded. Should this degraded condition continue to go unnoticed, the train would be unable to negotiate the mountainous terrain that it is approaching later in the journey.
- on-board sensors on the third locomotive identify the degraded cooling condition and data related to the degraded condition is immediately downloaded 40 to the data center 18 to update the data center database 38.
- Computers and/or personnel located at the data center 18 may analyze the data 48 and identify that the anomaly exists 58 and determine that a maintenance action 60 is recommended. For example, if a fan motor controller has developed a malfunction, a maintenance recommendation 60 to replace the control panel may be generated. A web page display showing the location of the locomotive would then be promptly updated 56 to show the degraded condition, and the railroad maintenance personnel are notified 62 by an electronic mail message that is automatically generated at the data center 18. The e-mail will include a Universal Resource Locator (URL) directing the maintenance personnel to an Internet web page containing information regarding the degraded condition and the recommended maintenance activity.
- URL Universal Resource Locator
- the maintenance personnel then view the available parts inventory 66 illustrated on another web page to verify the availability of the required control panel in a service center 22 located along the route of the locomotive 12.
- a user 14 is able to utilize the power of a global information network 15 web page presentation to quickly assess the importance of anomaly affecting one of a fleet of mobile assets and to assess various options for addressing such anomaly.
- the degraded locomotive may be repaired prior to the train becoming stalled on a mountainous section of the track, thereby avoiding a large out-of-pocket expense and a costly schedule delay for the transportation company.
- the speed of communication via the Internet and the breath of information that may be effectively communicated via an Internet web page make the communication system 10 of Figure 1 and the method of managing assets 28 of Figure 2 beneficial for a large fleet of mobile assets distributed over a large geographic area.
- Access to an Internet web page containing important information regarding a fleet of mobile assets may be restricted to only those users having appropriate authorization to access such data.
- information derived from the analysis 48 of the data base may be displayed on a password protected Internet web page. Only authorized users 14,24 would then be provided with the password necessary to gain access to the web page.
- information received from a user and used to update the web page 56 may only be accepted as authentic if the user enters an appropriate password to confirm his/her identity. Other protection measures such as encrypting data may also be used.
- the location of passenger trains may be information that can be made available on a public Internet web page, whereas the location of freight trains may be limited to only specific industrial customers of the railroad company.
- the present invention may further include a capability for predicting vehicle failure and for using such predictions to plan repair and maintenance work for each individual asset.
- One data is collected from the mobile assets, it may be used to develop a variety of types of information regarding the mobile assets.
- Such a capability includes monitoring on-board systems parameter data transmitted from each vehicle as it is operating; determining whether any of the monitored data is out of a predetermined range; calculating trends for monitored data determined to be out of range; identifying any system fault; predicting when such system is likely to fail unless corrected; and predicting which, if any, system must be corrected to avoid vehicle failure, developing a service recommendation, and communicating the service recommendation via a global information network.
- An apparatus to accomplish such steps is generally identified by numeral 110 of Figure 3, and it comprises a communication element(s) 112 and a monitoring station 114.
- Communication element(s) 112 are carried by the remote vehicle, for example locomotive 12.
- the communication element(s) may comprise a cellular modem, a satellite transmitter or similar well-known means or methods for conveying wireless signals over long distances.
- Signals transmitted by communication element 112 are received by monitoring station 114 that, for example, may be the maintenance facility 22 or data center 18 of Figure 1.
- Monitoring station 114 includes appropriate hardware and software for receiving and processing vehicle system parameter data signals generated by locomotive 12 from a remote location.
- Such equipment as illustrated in block diagram form in FIG. 4, comprises receiving element 116, processing element 118, and man-machine interface element 120.
- Suitable receiving element 116 include a satellite communications receiver or cellular communications receiver.
- Processing element 116 includes a satellite communications receiver or cellular communications receiver.
- Suitable processing element 118 may comprise a processor, memory and modem or Integrated Services Digital Network (ISDN) adapter of a conventional personal computer or workstation coupled with software capable of executing the functions represented in FIG. 4.
- Suitable processing element 118 may include a locomotive failure diagnostic system as described in U.S. Patent No. 5,845,272.
- Man-machine interface element 120 may include a monitor, keyboard, mouse, printer and/or other related I/O devices for enabling interaction between a human operator and processing means 118. Monitored vehicle parameter data received by receiving means 116 is communicated to processing element 118 wherein it is processed in the manner shown in FIG. 5. Many vehicle system operating parameters are monitored, and trends are calculated on a subset of those parameters, or on all of the parameters.
- monitored parameters may further include vacuum, fuel injection pressure, intake boost pressure, throttle position, etc.
- the monitored parameters may also include measurements of data important to the cargo 25 being transported by the mobile asset, for example the temperature in a refrigerated railcar or highway trailer. Referring to FIG. 5, there is shown a block diagram of the operations performed by processing element 118 upon receipt of vehicle systems parameter data transmitted by communication element 112.
- communication element 112 Upon issuance of a transmission request from monitoring station 114, communication element 112 preferably continuously transmits the data and receiving element 116 preferably continuously receives the data.
- processing element 118 monitors the data as indicated at 122.
- a first determination 124 made by processing element 118 is whether any of the data is outside of an acceptable range for any of the vehicle systems being monitored. If the processing element identifies out-of-range data, it executes a routine 126 to calculate whether the data suggests one or more trends suggestive of possible or actual impairment or failure of the vehicle systems being monitored.
- the trends are calculated by comparing values for a given parameter over a period of time and comparing those values with historical data for identical vehicle systems. This enables rapid and accurate correlation of trending data with a dedicated fault occurrence experience database.
- the trends are preferably calculated based in part on prior downloads collected in the database.
- the database is preferably continually updated and may be stored in the memory of processing element 118, elsewhere at the monitoring station 114, or off-site whereby it may be accessed on- line.
- Processing element 118 is preferably capable of linking the results of several observed trends to more precisely diagnose a problem. For instance, the aforementioned crankcase overpressure trend may be coupled by processing element 118 with an observed trend in electronic fuel injection parameters to more clearly determine the cause of the problem. Once an unfavorable trend is detected, it is identified by processing element 118 with a stored fault code as indicated at 128. Fault codes corresponding to a wide variety of faults may be stored, and trends may be calculated for some or all of them.
- faults examples include, without limitation, overcurrents, flashovers, crankcase overtemperatures, crankcase overpressures, communication failures, electrical ground failures, air conditioner converter failures, propulsion system faults, auxiliary system faults, propulsion motor faults, auxiliary motor faults, auxiliary system charging faults, engine cooling system faults, oil system faults, control wiring faults, and microelectronics faults.
- processing element 118 then prioritizes the fault.
- the fault prioritization process involves comparing the identified fault code with a historical fault database whereby the fault may be classified as critical, restrictive, or both critical and restrictive.
- a critical fault is one that will cause imminent vehicle shutdown if not immediately corrected.
- restrictive fault is one that, although not likely to cause imminent vehicle shutdown, impedes vehicle performance.
- a restrictive fault is likely to become progressively worse and may degenerate into a critical fault if not timely addressed.
- restrictive faults include, without limitation, an overheated engine or the loss of one or more traction motors, each of which deplete horsepower and may cause other strain on the engine or other systems of the vehicle.
- processing element 118 After a fault has been prioritized, processing element 118, as indicated at 132, predicts which vehicle system is likely to fail. Additionally, processing element also predicts the estimated time of failure, preferably expressed as an approximation of the distance (in miles or kilometers, for example) the vehicle can be safely operated before it must be shopped prior to failure or the amount of operating time prior to failure. The optimum time the vehicle should be shopped is determined by resorting to the relevant trend data for the identified fault and comparing that data with a projected time-of-failure knowledge base which has been inputted into the database for the calculation.
- processing element 118 is also preferably programmed to instruct a human operator at monitoring station 114: (1) whether to correct the fault prior to scheduled maintenance of the vehicle, (2) when to correct the fault, (3) what fault to correct (preferably including what parts or components of the vehicle to repair), and (4) the optimal facility at which to correct the fault.
- the optimal repair facility is dependent upon the proximity of the vehicle to a facility and whether the facility has the capability, including parts, service equipment and personnel expertise necessary to repair the fault.
