Abstract
A method for controlling the tension in a spooled device disposed on a winch, comprises providing an input signal to a controller indicative of a measured tension in the spooled device, providing an input signal to the controller indicative of a desired tension in the spooled device, and providing an output signal from the controller to adjust the speed of the winch based on a difference between the desired tension in the spooled device and the measured tension in the spooled device.
Claims18
A method for controlling the tension in a spooled device disposed on a winch, comprising:
- providing an input signal to a controller indicative of a measured tension in the spooled device, wherein the measured tension is measured by a cable mounted tension device;
- providing an input signal to the controller indicative of a desired tension in the spooled device;
- and
- providing an output signal from the controller to adjust the speed of the winch based on a difference between the desired tension in the spooled device and the measured tension in the spooled device.
A system for monitoring the tension of a spooled conveyance, comprising:
- an assembly for driving a winch;
- a conveyance spooled upon the winch;
- and
- a controller having at least a measured tension input and a desired tension input, the controller operable to output a signal to adjust the speed of the winch based on a difference between the desired tension in the spooled device and the measured tension in the spooled conveyance, wherein the measured tension input is measured by a cable mounted tension device.
