Abstract

A system and methods of impact avoidance for a load transport system are provided. The method includes coupling an elongated load to a transport vehicle, wherein the load includes a supported portion and a cantilevered portion such that the cantilevered portion exceeds a support dimension of the transport vehicle. The method further includes coupling at least one proximity sensor to the load, determining a distance from either the proximity sensor or the load to an object in the field of view of the sensor, transmitting the signal corresponding to the determined distance to a control unit, comparing the determined distance to a predetermined allowable clearance distance and generating a signal based on the comparison.

Claims

at least one proximity sensor coupled to a load, said at least one sensor comprising a field of view;

at least one control unit configured to receive a signal from said at least one proximity sensor; and

coupling at least one proximity sensor to the load, said sensor comprising a field of view;

determining a distance from at least one of the proximity sensor and the load to an object in the field of view of the sensor;

transmitting the signal corresponding to the determined distance to a control unit;

comparing the determined distance to a predetermined allowable clearance distance; and

generating a signal based on the comparison.

7. A method in accordance with claim 6, wherein transmitting a signal further comprises transmitting the determined signal to at least one of the control unit over a wireless network, the control unit over hard-wire, a cell phone and an email account.

8. A method in accordance with claim 6, wherein determining a distance to the object further comprises:

determining a position of at least one point on the load using the at least one proximity sensor;

determining a position of an approaching object relative to the determined point on the load; and

determining a distance therebetween.

9. A method in accordance with claim 6, wherein the load comprises a supported end and an opposing distal end and wherein coupling the at least one proximity sensor to a load further comprises coupling the at least one proximity sensor to the distal end of the load.
