摘要

An automated profiling system has been developed for obtaining water quality data in the upper 100 m of the water column. Design for unattended operation from remote battery-powered platforms such as telemetering buoys, the system requires as little as 1.5 Ah of energy for a 15-minute deploy-retrieve cycle. System hardware includes a sensor package, electromechanical cable, winch, winch controller, sensor readout unit, and data processing/control electronics. In order to minimize energy requirements for battery operation, a computer simulation was derived for defining system component performance characteristics. Variables in the simulation included sensor size and weight, cable diameter and specific gravity, winch drum width and diameter, winch motor speed-torque characteristic and drive train reduction ratio. Using a winch concept developed at Scripps Institution of Oceanography, the simulation was employed to iteratively size the winch components for a minimum energy configuration.
