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, a main reservoir tank containing pressurized fluid, and an independent brake containing pressurized fluid, the remote control system comprising:

a remote control device for transmitting signals;

a first controller module connected to the railway vehicle and in communication with the remote control device, the first controller module having a sensor for monitoring the pressure of the fluid contained in the main tank reservoir and providing an output from the sensor of the first controller module to the remote control device indicative of the pressure of the fluid contained in the main tank reservoir;

a second controller module connected to the railway vehicle and in communication with the remote control device, the second controller module having a sensor”

for monitoring the pressure of the fluid contained in the independent brake and providing an output from the sensor of the second controller module to the remote control device indicative of the pressure of the fluid contained in the independent brake, the first and second controller modules initiating the throttle to provide tractive power to the railway vehicle when the pressure of the fluid contained in the main tank reservoir”

is above a predetermined main tank reservoir level and the pressure of the fluid contained in the independent brake is below a predetermined independent brake level;

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;

an impact detection device to provide the warning signal to the remote control device when the remote control device is impacted above a predetermined impact level;

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; and

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.

2. The remote control system of claim 1 wherein the remote control system has a video display.

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

4. The remote control system of claim 2 wherein the video display has a touchscreen;

the touchscreen providing executable command options for the railway vehicle.

5. The remote control system of claim 4 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 remote control system is provided with a plurality of frequencies at which the remote control system is operable.

7. The remote control system of claim 6 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 device based upon permitted frequencies in a preselected area.

8. The remote control system of claim 6 wherein the remote control system is further provided with 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.

9. The remote control system of claim 8 wherein the warning signal provided to the remote control device comprises an audio warning or a visual warning.

10. The remote control system of claim 1 wherein the second controller module monitors a set of predetermined functions and receiving commands from the remote control device to control the set of predetermined functions of the railway vehicle.

11. The remote control system of claim 10 wherein the 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.
