Abstract

A serial train communication system employs a pair of ultrasonic transceivers oppositely mounted at each end of a railway car. Each ultrasonic transceiver is coupled to a controller and to an independent power source. The controller is further coupled to various apparatuses installed on the railway car and is capable of controlling operation thereof. A command signal sent from a locomotive cab travels between railway cars enabling control of various apparatuses of such railway cars and status signals from such apparatuses may be sent back to a locomotive cab event recorder. The controller and the power source may be attached to the railway car or to any such apparatus. In another embodiment, a single ultrasonic transceiver is installed within an air brake pipe enabling communication within a mixed railway car configuration.

Claims

1. A serial train communication system for a railway train, said serial train communication system comprising:

(a) a power source;

(b) a controller coupled to said power source;

(c) a first means for transmitting a sound wave associated with a command signal provided from at least one locomotive, said sound wave having a predetermined frequency, said first means engageable with one end of one of said at least one locomotive, a railway car and a combination thereof and coupled to said power source and said controller, said controller enabling said first means to transmit said sound wave in a first direction;

(d) a second means coupled to said power source and said controller for receiving said sound wave and for providing an output signal to said controller upon receiving said sound wave, said second means engageable with an opposed end of said one of said at least one locomotive, said railway car and said combination thereof and in alignment with said first means.

2. A serial train communication system according to claim 1, wherein said predetermined frequency is greater than an upper limit of human hearing.

3. A serial train communication system according to claim 1, wherein said power source is a battery.

4. A serial train communication system according to claim 1, wherein said controller executes a predetermined software algorithm.

5. A serial train communication system according to claim 1, wherein said first means is rigidly attached in a first predetermined location at a first end pocket and said second means is rigidly attached in a second predetermined location at an opposed second end pocket.

6. A serial train communication system according to claim 1, wherein said serial train communication system controls a brake system disposed within a wheel set, said brake system having at least a control means thereof coupled to said controller, whereby a command signal received by said controller via said receiving means activates said control means and engages said brake system with said wheel set.

7. A serial train communication system according to claim 1, wherein said serial train communication system includes an automatic set and release hand brake having a chain connection with a brake system disposed within a wheel set and having at least a brake applied valve coupled to said controller, whereby a command signal received by said controller via said second receiving means enables activation of said apply valve causing said chain to wind up and engage said brake system with said wheel set.

8. A serial train communication system according to claim 7, wherein said serial train communication system further includes a release valve coupled to said controller for releasing said chain and for disengaging said brake system from said wheel set.

9. A serial train communication system for a railway train having at least one locomotive and a predetermined plurality of railway cars serially coupled to said at least one locomotive, said serial train communication system comprising a plurality of communication assemblies, each of which is installed on said at least one locomotive and on a respective railway car, said communication assembly including:

(a) a power source;

(b) a controller coupled to said power source;

(c) a first sound transmission means associated with a sound wave having a predetermined frequency, said first sound transmission means attached at one end of said railway car and said locomotive and coupled to said power source and said controller; and

(d) a second sound transmission means associated with said sound wave, said second sound transmission means attached at an opposed end of said railway car and said locomotive in alignment with said first sound transmission means, said second sound transmission means coupled to said power source and said controller.

10. A serial train communication system according to claim 9, wherein said first sound transmission means is a transmitter.

11. A serial train communication system according to claim 9, wherein said second sound transmission means is a receiver.

12. A serial train communication system according to claim 9, wherein each of said first sound transmission means and said second sound transmission means is a transceiver including in combination a transmitter and a receiver and enabling a transmission of said sound wave in a first direction from said at least one locomotive to each of said plurality of said railway cars and enabling said transmission of said sound wave in a second direction from each of said plurality of said railway cars to said at least one locomotive, said first direction is associated with a command signal initiated within said at least one locomotive and said second direction is associated with a status feedback signal.

13. A serial train communication system according to claim 9, wherein said serial train communication system further includes a housing for encasing said first sound transmission means and said second sound transmission means, said housing having means for attachment.

14. A serial train communication system for a railway train having at least one locomotive and a predetermined plurality of railway cars serially coupled to said at least one locomotive, said serial train communication system comprising:

(a) a first sound transmission means associated with a sound wave having a predetermined frequency, said first sound transmission means installed within one of a first brake pipe and a first brake hose of said at least one locomotive;

(b) a first power source disposed within said locomotive and coupled to said first sound transmission means;

(c) a first controller coupled to said first power source, to said first sound transmission means and to a control means disposed within a cab of said at least one locomotive;

(d) at least one second sound transmission means associated with said sound wave, said at least one second sound transmission means installed within one of a second brake pipe and a second brake hose of at least one of said predetermined plurality of said railway cars;

(e) at least one second power source coupled to said at least one second sound transmission means; and

(f) at least one second controller coupled to said at least one second power source and to said at least one second sound transmission means, whereby a command signal initiated by said control means and received by said first controller enables said first sound transmission means to transmit said sound wave in a first direction, said sound wave is received by said at least one second sound transmission means enabling thereof to provide at least one output signal to said at least one second controller.

15. A serial train communication system according to claim 14, wherein said controller enables said at least one second sound transmission means to transmit said sound wave in a second direction, said second direction being opposite to said first direction.
