Abstract

There is disclosed a system, method, and apparatus for a truck or like vehicle wherein a power source is split and/or divided into a plurality of branch power lines and wherein there is data and power transmitted over the power lines to selected systems and/or subsystems. An intelligent isolation module is provided for selectively transmitting, blocking, and/or altering data and/or power on any branch, sub-branch, and/or selected segment of a branch.

Claims

1. In an electrical system for a truck or like vehicle comprising one or more power lines containing one or more power line data receivers and transmitters, the improvement wherein a power line data filter is incorporated in at least one power line carrying data, such that data is blocked from passing through the data filter at all times, said data filter isolating data on one segment of the power line from data on the other segment of the same power line, such that each isolated data segment has the ability to transmit and receive unique data independently from the other isolated data segment of the same power line.

2. The invention of claim 1 wherein said data filter isolates or connects power on both sides of said filter.

3. The invention of claim 1 wherein one or more power line data transmitters and receivers are connected to both segments on each side of said data filter.

4. The invention of claim 3 wherein data control circuitry is connected to the power line data transmitters and receivers on the isolated data segments on each side of said filter.

5. The invention of claim 4 wherein said data control circuitry is connected to said data filter for the control of power flow through the filter.

6. The invention of claim 4 wherein said data control circuitry includes a microprocessor.

7. The invention of claim 3 wherein the data control circuitry is connected to data control circuitry on another power line.

8. In an electrical system for a truck or like vehicle comprising one or more power lines containing one or more power line data transmitters and receivers, the improvement wherein an intelligent isolation module is incorporated into a power line that is carrying data, said intelligent isolation module containing a data filter that isolates data on one segment of the power line from the data on another segment on the same power line, said intelligent isolation module containing two or more power line data transmitters and receivers connected to the isolated data segments on the power line, said intelligent isolation module further containing data control circuitry connected to the power line data transmitters and receivers so as to allow data to be passed from one segment to another segment.

9. The invention of claim 8 wherein the data received by a power line data transmitter and receiver on one isolated data segment is passed to the data control circuitry and said data control circuitry passes the data unaltered to the power line data transmitter and receiver on the other isolated data segment.

10. The invention of claim 8 wherein the data received by a power line data transmitter and receiver on one isolated data segment is passed to the data control circuitry and said data control circuitry alters and passes the data to the power line data transmitter and receiver on the other isolated data segment.

11. The invention of claim 8 wherein the data received on one isolated data segment is passed to the data control circuitry and said data control circuitry blocks the data so the data is not transmitted on the other isolated data segment.

12. The invention of claim 8 wherein the data received on one isolated data segment is passed to the data control circuitry and said data control circuitry passes the data unaltered to the data control circuitry of a different intelligent isolation module on a different power line.

13. The invention of claim 8 wherein the data received on one isolated data segment is passed to the data control circuitry and said data control circuitry alters and passes the data to the data control circuitry of a different intelligent isolation module on a different power line.

14. The invention of claim 8 wherein two or more intelligent isolation modules are connected together so that data can be transmitted between said intelligent isolation modules.

15. The invention of claim 8 wherein the data received on one isolated data segment is passed to the data control circuitry and said data control circuitry disconnects the power passing through the data filter connecting the two isolated data segment.

16. The invention of claim 8 wherein the data received on one isolated data segment is passed to the data control circuitry, said received data containing embedded commands to direct the transmission of power and/or data.

17. The invention of claim 8 wherein independent data is transmitted over both isolated data segments at the same time.

18. The invention of claim 8 wherein the data control circuitry acts as a bi-directional gate to allow data to be passed back and forth between the two isolated data segments on either side of the data filter.

19. In an electrical system for a truck or like vehicle containing one or more power lines wherein data is being transmitted over one or more power lines of said vehicle, the improvement wherein one or more data filters are incorporated into said power line to isolate data on one segment of the power line from another segment of the same power line, wherein each filter has power line data transmitter and receiver on each side of the filter and data control circuitry, where said data control circuitry acts as a bi-directional data gate between the isolated power line segments on either side of said filter.

20. The invention of claim 19 wherein the data received by a power line data transmitter and receiver on one isolated data segment is passed to the data control circuitry and said data control circuitry, acting as a bi-directional gate, passes unaltered data to the power line data transmitter and receiver on the other isolated data segment.

21. The invention of claim 19 wherein the data received by a power line data transmitter and receiver on one isolated data segment is passed to the data control circuitry and the data control circuitry, acting as a bi-directional gate, passes altered data to the power line data transmitter and receiver on the other isolated data segment.

22. The invention of claim 19 wherein the data received on one isolated data segment is blocked and not transmitted on the other isolated data segment.

23. The invention of claim 19 wherein the data received on one isolated data segment is transmitted to a different intelligent isolation module on a different power line.

24. The invention of claim 19 wherein two or more intelligent isolation modules are connected together so that data can be transmitted between said intelligent isolation modules.

25. The invention of claim 19 wherein independent data is transmitted over both segments at the same time.
