Abstract

A sensor system for road construction equipment. The system includes a first conveyor for transporting material to a first auger that is positioned to receive the material. A first feeder sensor associated with the first conveyor is in over-the-air communication with a receiver to communicate the height of a material on the conveyor such that a master controller that is electrically connected to the receiver can regulate the amount of flow of material to the first conveyor.

Claims

1. A sensor system for construction equipment comprising:

a first feeder for transporting material;

a first auger positioned to receive the material from the first feeder;

a first feeder sensor associated with the first feeder and having a transceiver;

a receiver having a first transceiver in over-the-air communication with the first feeder sensor to receive information from the transceiver of the first feeder sensor; and

a master controller electrically connected to the receiver to receive communication from the receiver to control the flow of material onto the first feeder.

2. The sensor system of claim 1 further comprising:

a first auger sensor associated with the first auger and having a transceiver that communicates information to the receiver.

3. The sensor system of claim 2 further comprising:

a second feeder for transporting the material adjacent the first feeder and having a second feeder sensor associated therewith wherein the second feeder sensor communicates with the receiver.

4. The sensor system of claim 3 further comprising:

a second auger positioned to receive the material from the second feeder and having a second auger sensor associated therewith for communicating information to the receiver.

5. The sensor system of claim 1 wherein the first transceiver of the receiver is a wireless radio link.

6. The sensor system of claim 1 wherein the receiver has a second transceiver that scans radio channels.

7. The sensor system of claim 6 wherein based on the radio channels scanned the receiver communicates with the first feeder sensor to change a radio channel of the first feeder sensors.

8. The sensor system of claim 1 wherein the receiver transmits a time triggered beacon to the first feeder sensor.

9. The sensor system of claim 8 wherein the first feeder sensor communicates information in response to receiving the time triggered beacon to the receiver.

10. The sensor system of claim 9 wherein the receiver communicates the information communicated from the first feeder sensor to the master controller.

11. The sensor system of claim 10 wherein the master controller controls the flow of material to the first feeder based on the information communicated to the master controller.
