Abstract

The present invention is directed to a remote control system for controlling a railway vehicle. The remote control system including a remote control device for transmitting signals to a first controller module. The first controller is mounted to the railway vehicle and controls and monitors the functions of the railway vehicle. The first controller module also relays information to the remote control device. The remote control system can also include a portable safety switch allowing any individual in proximity to the railway vehicle to send a stop signal to the first controller module to stop the railway vehicle if any unsafe conditions exist.

Claims

1. A remote control system for controlling a railway vehicle, the railway vehicle having a throttle for providing tractive power to the railway vehicle to propel the railway vehicle and a brake system for providing braking power to the railway vehicle, the remote control system comprising:

a remote control device for transmitting signals, the remote control device having a video display to display real time information of the railway vehicle, the video display having a touchscreen the touchscreen providing executable command options for the railway vehicle;

a first controller module connected to the railway vehicle and in communication with the remote control device, the first controller module monitoring a set of predetermined functions of the railway vehicle and receiving commands from the remote control device to control the set of predetermined functions of the railway vehicle, the first controller module providing the real time information to the remote control device;

a tilt recognition device to provide a warning signal to the remote control device when the remote control device is tilted a predetermined amount from a substantially level position;

the tilt recognition device provides the warning signal for a predetermined amount of time before the remote control system enters into a fault condition;

the fault condition avoidable by a cancellation of the warning signal by a user of the remote control device or repositioning the remote control device in the substantially level position; and

the warning signal provided to the remote control device comprises an audio warning or a visual warning.

2. The remote control system of claim 1 wherein the video display has a diagonal length that is greater than about 2.5 inches.

3. The remote control system of claim 1 wherein the large video display has a diagonal length that is greater than about 5 inches.

4. The remote control system of claim 1 wherein the touchscreen is selected from the group consisting of a resistive touchscreen, an infrared touchscreen, a surface acoustic wave touchscreen, a capacitive touchscreen, a strain gauge touchscreen, an optical imaging touchscreen, a dispersive signal touchscreen, an acoustic pulse recognition touchscreen, and a frustrated total internal reflection touchscreen.

5. The remote control system of claim 1 wherein the video display is provided with backlighting to improve visibility of the displayed information.

6. The remote control system of claim 1 wherein the information displayed on the video display can be changed by an operator of the remote control device so as to provide a different set of information and command options actionable via the touchscreen.

7. The remote control system of claim 1 wherein the remote control system is provided with a plurality of frequencies at which the remote control system is operable.

8. The remote control system of claim 7 wherein the remote control system operates at two different frequencies selected from the plurality of frequencies at which the remote control system is operable, the two different frequencies are manually selected by the user of the remote control system or automatically by the remote control system based upon permitted frequencies in a preselected area.

9. The remote control system of claim 1 wherein the remote control system is further provided with a vibration detection device to provide the warning signal to the remote control device when the remote control device is vibrated a predetermined amount from a substantially stable position;

the vibration detection device provides the warning signal for a predetermined amount of time before the remote control system enters into a fault condition;

the fault condition avoidable by a cancellation of the warning signal by a user of the remote control device or repositioning the remote control device in the substantially stable position.

10. The remote control system of claim 1 wherein the remote control system is further provided with an impact detection device to prove the warning signal to the remote control device when the remote control device is impacted above a predetermined impact level.

11. The remote control system of claim 10 wherein the impact detection device further provides a second warning signal to the remote control device when the remote control device is impacted above a second predetermined impact level;

the impact detection device providing the second warning signal to the remote control device for a predetermined amount of time before the remote control system enters into a default condition, the fault condition avoidable by a cancellation of the warning signal by a user of the remote control device.

12. The remote control system of claim 1 wherein the remote control system further comprises a second controller module connected to the railway vehicle, the second controller module monitoring a second set of predetermined functions and receiving commands from the remote control device to control the second set of predetermined functions of the railway vehicle.

13. The remote control system of claim 12 wherein the set of predetermined functions and the second set of predetermined functions are selected from the group consisting of pressure of the fluid in a main reservoir, pressure of a fluid in an independent brake, pressure of a fluid in a train brake, the throttle, the braking system, and combinations thereof.
