A Microprocessor Based Underwater Data Acquisition System

摘要

A self-contained, underwater, microprocessor controlled data acquisition system is described. The system was designed, constructed, programmed, and then successfully operated in the ocean off the coast of Florida. The design includes very low power consumption allowing operation from internal rechargeable batteries, control of system functions by firmware, internal digital cassette storage, and the ability to perform two-way communications with a shore based computer terminal or remotely located computer via telephone data communications. The system was programmed to operate in two modes: a field station mode in which the data are collected by a remote computer and a storm mode in which data are automatically recorded internally.
