Automation Techniques for Physical Hydraulic Models.
Abstract
Automated Data Acquisition and Control Systems (ADACS) have been designed and built at the Waterways Experiment Station for the purpose of collecting data and controlling operations of physical hydraulic models. The computer hardware configuration for each system consists of a minicomputer; various peripheral devices such as magnetic tape, disc, card readers, etc.; interval timers; analog to digital converters and multiplexer or Serdex system with interfacing equipment; teletype; model control interfacing; and a printer/plotter. The ADACS are capable of automatically calibrating model sensors, controlling model operation, acquiring data from the sensors at a high sampling rate, and analyzing test data. Data are taken and recorded on disc or magnetic tape for direct analyses by the minicomputer system or on magnetic tape in a format compatible with larger computing facilities for backup analyses. Such automation techniques for hydraulic modeling has greatly reduced the time and cost of physical model testing, has improved the quality and quantity of model data, and has allowed more sophisticated procedures for data analyses and model tests than could be performed in the past.
