Abstract

A control system for monitoring a work train for performing track maintenance operations has a computer connected to receive information from a multitude of work vehicles constituting the work train. A respective vehicle identifying device is associated with each work vehicle, the vehicle identifying device being connected communicate with the computer (e.g., via a control line) and configured for storing vehicle characteristics defining the respective work vehicle. The computer connected to the control line includes a display for visually indicating, in the case of a malfunction report concerning a particular work vehicle, the respective vehicle characteristics in connection with the position of the respective vehicle within the work train.

Claims

1. A work train for performing track maintenance operations, the work train being mobile on a track and comprising:

a plurality of work vehicles, disposed one after another on the track and releasably connected to one another;

working devices respectively associated with individual said work vehicles, said working devices cooperating for achieving a common work result for the work train;

a control system for monitoring the work train, the control system including;

a communication device connecting said work vehicles to one another;

vehicle identifying devices respectively associated with said work vehicles, each of said vehicle identifying devices being connected to said communication device and configured for storing vehicle characteristics defining the respective said work vehicle; and

a computer connected to said communication device and including a display, said computer being configured for visually displaying a malfunction report generated as a result of a detected difference between actual and desired values of parameters essential for disturbance-free operation of a particular working device, wherein the malfunction report is combined with the vehicle characteristics of the work vehicle associated with the said working device.

2. The control system according to claim 1, wherein said communication device includes a control line extending between the work vehicles and connecting said computer to each of the work vehicles.

3. The control system according to claim 1, wherein said display is configured for displaying visual indicator units associated respectively with said work vehicles and corresponding in number to a number of work vehicles in the work train, said indicator units being activatable in case of a corresponding malfunction report.

4. The control system according to claim 3, wherein said visual indicator units are arranged on said display in a sequence corresponding to a sequence of the work vehicles in the work train.

5. The control system according to claim 1, wherein each vehicle identifying device is further associated with a maintenance counter for tracking maintenance intervals prescribed for the respective said working device, and a time keeper activatable automatically after actuation of the respective said working device.

6. A method of monitoring a work train for performing track maintenance operations, the work train being mobile on a track and being composed of a plurality of work vehicles disposed one after another on the track, the work vehicles having working devices, which comprises:

transmitting vehicle characteristics identifying a respective work vehicle to a computer;

displaying the vehicle characteristics on a display of the computer in a sequence corresponding to a sequence of the work vehicles in the work train; and

displaying malfunction information concerning a given work vehicle resulting from a difference between actual and desired values of parameters essential for a disturbance-free operation of the respective working devices on the display of the computer in connection with the respective vehicle characteristics and the position of the work vehicle within the work train.

7. The method according to claim 6, which comprises evaluating the malfunction information, by comparing the information to stored reference values, with regard to an influence thereof on continued unhindered working operation by the work train, and displaying a malfunction report on the display of the computer in different ways visually in dependence on the evaluation.

8. The method according to claim 7, which comprises shutting off all drives of working devices of the work vehicles in the work train if a malfunction report is evaluated as being significant.

9. In combination with a work train for performing track maintenance operations, the work train including a plurality of work vehicles disposed one after another on a track in a given sequence order and releasably connected to one another, and a plurality of working devices respectively associated with individual said work vehicles, said working devices cooperating for achieving a common work result for the work train, a control system for monitoring the work train, the control system comprising:

vehicle identifying devices respectively associated with individual work vehicles of the work train and each being configured for storing vehicle characteristics defining the respective said work vehicle;

a computer with a display; and

a communication system connecting said computer with each of the vehicle identifying devices and for receiving from the individual work vehicles information concerning an operational status of the respective working device;

said computer being configured for visually displaying a malfunction report generated as a result of a detected difference between actual and desired values of parameters essential for disturbance-free operation of a particular working device, wherein the display combines the malfunction report with the vehicle characteristics of the work vehicle associated with the respective working device.

10. The control system according to claim 9, wherein said communication system includes a control line extending between the work vehicles and connecting said computer to each of the work vehicles.

11. The control system according to claim 9, wherein said display is configured for displaying visual indicator units associated respectively with said work vehicles and corresponding in number to a number of work vehicles in the work train, said indicator units being activatable in case of a corresponding malfunction report.

12. The control system according to claim 11, wherein said visual indicator units are arranged on said display in a sequence corresponding to a sequence of the work vehicles in the work train.

13. The control system according to claim 9, wherein each vehicle identifying device is further associated with a maintenance counter for tracking maintenance intervals prescribed for the respective said working device, and a time keeper activatable automatically after actuation of the respective said working device.
